Drag and Drop Questions 1
Here you will find answers to Drag and Drop Questions – Part 1
Question 1
Drag the data center property on the left to the design aspect on the right it is most apt to affect
Answer:
Space: amount of racks, equipment, cabling, people
Weight load: rack servers vs blade servers
Power: variability of computing load, computing power and memory requirements
Cooling: arranging equipment racks face-to-face or back-to-back
Cabling: abundant, variable, well organized and easy to maintain
Security: disasters, fire suppression and alarm systems
Explanation
The data center space includes number of racks for equipment that will be installed. Other factor needs to be considered is the number of employees who will work in that data center.
Rack servers are low cost and provide high performance, unfortunately they take up space and consume a lot of energy to operate. Blade servers provide similar computing power when compared to rack mount servers, but require less space, power, and cabling. The chassis in most blade servers allows for shared power, Ethernet LAN, and Fibre Channel SAN connections, which reduce the number of cables needed.
The power in the data center facility is used to power cooling devices, servers, storage equipment, the network, and some lighting equipment. In server environments, the power usage depends on the computing load place on the server. For example, if the server needs to work harder by processing more data, it has to draw more AC power from the power supply, which in turn creates more heat that needs to be cooled down.
Cooling is used to control the temperature and humidity of the devices. The cabinets and racks should be arranged in the data center with an alternating pattern of “cold” and “hot” aisles. The cold aisle should have equipment arranged face to face, and the hot aisle should have equipment arranged back to back. In the cold aisle, there should be perforated floor tiles drawing cold air from the floor into the face of the equipment. This cold air passes through the equipment and flushes out the back into the hot aisle. The hot aisle does not have any perforated tiles, and this design prevents the hot air from mixing with the cold air.
The cabling in the data center is known as the passive infrastructure. Data center teams rely on a structured and well-organized cabling plant. It is important for cabling to be easy to maintain, abundant and capable of supporting various media types and requirements for proper data center operations.
Fire suppression and alarm systems are considered physical security and should be in place to protect equipment and data from natural disasters and theft.

Question 2
Drag the WAN characteristic on the left to the branch office model where it would most likely be used on the right
Answer:
Small Office:
+ redundant links
+ internet deployment model
Medium Office:
+ redundant devices
+ private WAN deployment
Large Office:
+ MPLS deployment model
+ redundant links and devices
Explanation
Small Office:
The small office is recommended for offices that have up to 50 users. The Layer 3 WAN services are based on the WAN and Internet deployment model. A T1 is used for the primary link, and an ADSL secondary link is used for backup.
Medium Office:
The medium branch design is recommended for branch offices of 50 to 100 users. Medium Offices often use redundancy gateway services like Hot Standby Router Protocol (HSRP) or Gateway Load Balancing Protocol (GLBP).
Private WAN generally consists of Frame Relay, ATM, private lines, and other traditional WAN connections. If security is needed, private WAN connections can be used in conjunction with encryption protocols such as Digital Encryption Standard (DES), Triple DES (3DES), and Advanced Encryption Standard (AES). This technology is best suited for an enterprise with moderate growth outlook where some remote or branch offices will need to be connected in the future.
Dual Frame Relay links in medium office provide the private WAN services, which are used to connect back to the corporate offices via both of the access routers.
Large Office:
The large office supports between 100 and 1000 users. The WAN services use an MPLS deployment model with dual WAN links into the WAN cloud -> MPLS & redundant links.

Question 3
Drag the security provision on the left to the appropriate network module on the right
Answer:
Access:
+ Protect network services including DHCP, ARP, and IP spoofing protection
+ Protect against inadvertent loops
Distribution:
+ Protect the endpoints using network based intrusion prevention
+ Protect the infrastructure using NFP best practices
Core:
+ Does not perform security functions to mitigate transit threats
+ Filter and rate-limit control plane traffic
Explanation
Rate limiting controls the rate of bandwidth that incoming traffic is using, such as ARPs and DHCP requests.
Access layer:
Some security measures used for securing the campus access layer, including the following:
* Securing the endpoints using endpoint security software
* Securing the access infrastructure and protecting network services including DHCP, ARP, IP spoofing protection and protecting against inadvertent loops using Network Foundation Protection (NFP) best practices and Catalyst Integrated Security Features (CISF).
Distribution layer:
Security measures used for securing the campus distribution layer including the following:
* Protecting the endpoints using network-based intrusion prevention
* Protection the infrastructure using NFP best practices
Core layer:
The primary role of security in the enterprise core module is to protect the core itself, not to apply policy to mitigate transit threats traversing through the core.
The following are the key areas of the Network Foundation Protection (NFP) baseline security best practices applicable to securing the enterprise core:
* Infrastructure device access—Implement dedicated management interfaces to the out-of-band (OOB) management network, limit the accessible ports and restrict the permitted communicators and the permitted methods of access, present legal notification, authenticate and authorize access using AAA, log and account for all access, and protect locally stored sensitive data (such as local passwords) from viewing and copying.
* Routing infrastructure—Authenticate routing neighbors, implement route filtering, use default passive interfaces, and log neighbor changes.
* Device resiliency and survivability—Disable unnecessary services, filter and rate-limit control-plane traffic, and implement redundancy.
* Network telemetry—Implement NTP to synchronize time to the same network clock; maintain device global and interface traffic statistics; maintain system status information (memory, CPU, and process); and log and collect system status, traffic statistics, and device access information.

Question 4
Drag the Campus Layer Design on the left to the appropriate location on the right
Answer:
Access:
+ routing boundary (dynamic, summarization, static)
+ the most feature-rich parts of the campus network
Distribution:
+ enforces policy within the network
+ provide security, QoS, and IP multicast to network
Core:
+ high level of availability, scalability and fast convergence
+ provides a limited set of services
Explanation
Campus Access Layer Network Design
The access layer is the first tier or edge of the campus, where end devices such as PCs, printers, cameras, Cisco TelePresence, etc. attach to the wired portion of the campus network. The wide variety of possible types of devices that can connect and the various services and dynamic configuration mechanisms that are necessary make the access layer one of the most feature-rich parts of the campus network.
Campus Distribution Layer
The campus distribution layer provides connectivity to the enterprise core for clients in the campus access layer. It aggregates the links from the access switches and serves as an integration point for campus security services such as IPS and network policy enforcement.
Distribution layer switches perform network foundation technologies such as routing, quality of service (QoS), and security.
Core Layer
The core layer provides scalability, high availability, and fast convergence to the network. The core layer is the backbone for campus connectivity, and is the aggregation point for the other layers and modules in the Cisco Enterprise Campus Architecture. The core provides a high level of redundancy and can adapt to changes quickly. Core devices are most reliable when they can accommodate failures by rerouting traffic and can respond quickly to changes in the network topology. The core devices implement scalable protocols and technologies, alternate paths, and load balancing. The core layer helps in scalability during future growth.
The campus core is in some ways the simplest yet most critical part of the campus. It provides a very limited set of services and is designed to be highly available and operate in an “always-on” mode. In the modern business world, the core of the network must operate as a non-stop 7x24x365 service.
Note:
It is a difficult question! Some characteristics are present at more than one layer so it is difficult to classify correctly. For example, a Cisco site says:
“The campus distribution layer acts as a services and control boundary between the campus access layer and the enterprise core. It is an aggregation point for all of the access switches providing policy enforcement, access control, route and link aggregation, and the isolation demarcation point between the campus access layer and the rest of the network.”
It means that the “routing boundary” should belong to the Distribution Layer instead of Access Layer. But the Distribution Layer also “enforces policy within the network” & “provide security, QoS, and IP multicast to network”.
After a lot of research, I decide to put the “routing boundary” to the Access Layer because this feature seems to be at the border of Access & Distribution layers so we can choose either. The “provide security, QoS, and IP multicast to network” features mainly belong to the Distribution layer (the Official 640-864 CCDA mentions about QoS, Security filtering & Broadcast or multicast domain definition in the Distribution layer)

Question 5
Drag the WAN technology on the left to the most appropriate category on the right
Answer:
Leased:
+ TDM
+ SONET
Shared:
+ Frame-Relay
+ MPLS
Explanation
TDM & SONET are circuit-based so they are leased-line while Frame-Relay & MPLS are shared-circuit or packet-switched WAN
Question 6
Drag the technology on the left to the type of enterprise virtualization where it is most likely to be found on the right
Answer:
Network Virtualization:
+ VLAN
+ vPC
+ VRF
Device Virtualization:
+ ASA firewall context
+ IPS
+ VDC
Explanation
Network virtualization encompasses logical isolated network segments that share the same physical infrastructure. Each segment operates independently and is logically separate from the other segments. Each network segment appears with its own privacy, security, independent set of policies, QoS levels, and independent routing paths.
Here are some examples of network virtualization technologies:
* VLAN: Virtual local-area network
* VSAN: Virtual storage-area network
* VRF: Virtual routing and forwarding
* VPN: Virtual private network
* vPC: Virtual Port Channel
Device virtualization allows for a single physical device to act like multiple copies of itself. Device virtualization enables many logical devices to run independently of each other on the same physical piece of hardware. The software creates virtual hardware that can function just like the physical network device. Another form of device virtualization entails using multiple physical devices to act as one logical unit.
Here are some examples of device virtualization technologies:
* Server virtualization: Virtual machines (VM)
* Cisco Application Control Engine (ACE) context
* Virtual Switching System (VSS)
* Cisco Adaptive Security Appliance (ASA) firewall context
* Virtual device contexts (VDC)
(Reference: CCDA 640-864 Official Cert Guide)
Question 7
Drag the network function on the left to the functional area or module where it is most likely to be performed in the enterprise campus infrastructure on the right
Answer:
Enterprise Campus: enables intelligent route and switch, high availability resilient multilayer design and integrated security
Enterprise Edge: aggregates connectivity to voice, video, and data outside the enterprise with Qos and security
E-Commerce: supports application traffic through the Internet, initiated outside the enterprise network
Internet Connectivity: provides internal users with external HTTP, FTP, SMTP and DNS connectivity
Remote Access and VPN: terminates traffic that is forwarded by the Internet connectivity module
Data Center: enables service-oriented architectures, virtualization and secure computing with load balancing, redundancy
Access:
+ Protect network services including DHCP, ARP, and IP spoofing protection
+ Protect against inadvertent loops
Distribution:
+ Protect the endpoints using network based intrusion prevention
+ Protect the infrastructure using NFP best practices
Core:
+ Does not perform security functions to mitigate transit threats
+ Filter and rate-limit control plane traffic
Q1 answered incorrect: please check down,
Although rack servers are low cost and provide high performance, unfortunately they take up space and consume a lot of energy to operate. Because both rack space and power cost money, efficiency gains need to be considered in these areas.
Blade servers provide similar computing power when compared to rack mount servers, but require less space, power, and cabling. The chassis in most blade servers allows for shared power, Ethernet LAN, and Fibre Channel SAN connections, which reduce the number of cables needed.
———–
so: rack serv.(more power) vs blade serv.(less power) :power difference
weight load is compute power….rack and blade are almost same
For question 6, whatabout IPS? that’s a device virtualization? that should be an intrusion prevention system.
A little help/clarification please…
Clarification if anyone dan help please:
Q3 – all NFP information I can find (even above) is about the core, so is NFP best practices not core and rate limiting control plane traffic not distribution (QoS)?
The rest seems to make sense.
also
Q4 – I am getting conflicting information between here and testking regarding wether core or access is the most feature rich, and which provides limited services?
Thanks in advance
Q1. I am thinking in this way….
Space: rack servers vs blade servers -> it is about the size (Blade servers provide similar computing power when compared to rack mount servers, but require less space, power, and cabling.)
Weight load: amount of racks, equipment, cabling, people -> all added up the weight and the floor/platform can be supported.
10. Which two fauteres are supported at all three levels of the Cisco three-layer hierarchical model? (Choose two.)Needs a second awnser !!! * Quality of Service * link aggregation
Passed today 970/1000. Used lead2pass dump and studied the 640-864 official cert guide.
Almost all of the questions were from the lead2pass dump.
Drag and drop question were from the dump and dstut. But i suggest u can check 2-3 new DDs from the dump.
If u study the dump and dstut, you will pass.
Thanks everybody and good luck for all :)
Vicent – could you please send me the lead2pass dump @ galaco143@gmail.com. THANKS!!!
Vicent – would very much appreciate if you could also help to send me the lead2pass dump @ llaicg@gmail.com. THANKS!!!
@Vicent, like the others, i would like to request for the lead2pass dump if you could, i have my exam in 3 days, have read the 640-864 e-books but would like to back that up with proper dump just for exam. my email is: mymsnacc[at]hotmail.com Thanks mate :-)!
Hi every1, vincent, congratulations on ur scores, I need ur help guys in obtaininng d e book and dumps for this exams. My email is sifo80@yahoo.com. Thank u
Your conclusion of question 4 is wrong, although thats mine conclusion.
‘Provide security’ refers to port security, ‘QoS’ is done on all layers and’ IP multicast to network’ refers to CGMP (or IGMP snooping) at layer 2(so access) in combination with IGMP at layer 3. This again refers to a switched layer campus design in where the layer 3 boundary rest at the distribution layer the “routing boundary” Summarization is also perforemd at the distribution layer and not the access layer.
So the answer should read;
Answer:
Access:
+ provide security, QoS, and IP multicast to network
+ the most feature-rich parts of the campus network
Distribution:
+ enforces policy within the network
+ routing boundary (dynamic, summarization, static)
Core:
+ high level of availability, scalability and fast convergence
+ provides a limited set of services

So Im a little ticked off at the lead2pass 261q and anonymous VCEs. Alot of the questions come straight from the the CCDA exam which, as good as the information is to know, is not needed for the new CCDA exam and should not be in the VCEs to possible cause confusion. Not only this but there are a number of discrepencies between the 2 so as always, you better know and understand the theories instead of just relying on the dumps to pass the exams.
Valuable info. Fortunate me I discovered your website by chance, and I’m stunned why this twist of fate didn’t happened in advance! I bookmarked it.
Where can I find new Drag and Drops?. I was failed yesterday because I found 50% new drag and Drops in the exam. around 15 DD where there in exam.
Hi, anyone can send me the CCDA 640-864 pdf study Guide…appreciate your help greatly..thank you. (email: samteo25@yahoo.com)

Completing what ben said about Q1: “Blade servers provide similar computing power when compared to rack mount servers, but require less space, power, and cabling. The chassis in most blade servers allows for shared power, Ethernet LAN, and Fibre Channel SAN connections, which reduce the number of cables needed.” – Cisco Press CCDA Official Cert Guide 4th edition
Hi Guys,
For Q1 the answer is correct, when you mention weight load it is refering to the physical weight or load that you can install within a datacenter.. Pls dont confuse this with “computation weight or load”.
“Power” = in this question refers to electricity. Its consumption is determined by “computational load” on the server. Take note this only one factor to be considered. Since, you need to conisder effects on the PACU and UPS.
If you play around with iDRAC or iLO and any sizers when you increase the overal usage of the system, consumed power will increase. “Which increases power consumption”
Thanks.
Hi Everybody,
Can somebody please let me know if there is any labs for the Wireless exam or is there only questions and drag & drops?
How did you practice CCNA Wireless Labs ?
Please help, for more my email is flamur.dinaj@hotmail.com
need help please
is there any lab for the ccda exam ????
q6 answers are correct. see cisco documentation!
Q7 has some items wrong:
Enterprise Edge should be: terminates traffic that is forwarded by the Internet connectivity module
Remote Access and VPN should be: aggregates connectivity to voice, video, and data outside the enterprise with Qos and security
Hello
I’d like to know there is any simulation in CCDA exam.
Please answer…
Can someone confirm that the answer to the first Drag and Drop is correct:
Space: amount of racks, equipment, cabling, people
Weight load: rack servers vs blade servers
Power: variability of computing load, computing power and memory requirements
Cooling: arranging equipment racks face-to-face or back-to-back
Cabling: abundant, variable, well organized and easy to maintain
Security: disasters, fire suppression and alarm systems
also for Q4, is the answer correct:
Access:
+ routing boundary (dynamic, summarization, static)
+ the most feature-rich parts of the campus network
Distribution:
+ enforces policy within the network
+ provide security, QoS, and IP multicast to network
Core:
+ high level of availability, scalability and fast convergence
+ provides a limited set of services
@Anon
In my opinion your D&D answer on the datacenter is correct but this is by deduction. Assuming that on Security and Cabling there is no confusion, the real question is about Cooling, Weight, Power and Space.
arranging equipment racks face-to-face or back-to-back
This must refer to Cooling as changing from face-to-face to back-to-back does not change Weight, Power or anything else
amount of racks, equipment, cabling, people
This could fit Space and Weight but not Power as people don’t use power. I choose for Space as it mentions the amount of racks not the content of these racks. Also, cabling does not really add to the weight when compared to the weight of the racks.
rack servers vs blade servers
This could fit Space, Weight and Power. So last to solve
variability of computing load, computing power and memory requirements
This only fits Power as the space doesn’t change with the memory requirements and the weight change is minimal.
The leaves Weight for ‘rack servers vs blade servers’. This makes sense as there is a real weight difference between rack servers and blade servers as blades share power supplies so for the same amount of servers, a rack with blades weighs less. However, with blades much more servers fit in a rack, so full rack with blades will be much heavier as well. Regardless the point of view, the difference here is Weight.
Can I write the CCDP exams with my CCNA and CCNP? Please send me any comment through paransey4u@yahoo.com
Really difficult question and it’s all up to the interpretation of the individual. For Q1 it could also be argued that rack servers vs blade servers = SPACE while amount of racks, equipment, cabling, people = weight load.
Amount of racks means more racks equals more weight. Equipment would generally be put inside the racks so the space taken would be the same as the volume of space the rack takes for itself but its weight load would be heavier. The amount of cables in a DC also takes space but it can also be significantly heavy when taken in its totality and its weight does need to be taken into consideration when installing suspended cages if run through the ceiling, in tracks under the floor panels, and the weight and pressure of the rack on the floor will also increase when the cables are run inside a fully loaded rack or patch panel. More people in the DC also equal more weight.
10 rack servers take up more space than 10 blades in a chassis. There would also be a huge difference in weight so in the absence of paragraph above weight would also be correct. However since SPACE is the only answer that’s left and it also does affect space, you couldn’t go wrong choosing space as well.
Hi to all! Tomorrow I have the exam and some comments about the Q1 caused me confusion. Is there somebody able to give me the exact answer and the motivation? Thanks in advance
Hi Alberto and all !!! I am planning to take CCDA exam next week, could someone help me to get CCDA dumps. I need them urgently.
Do the lead2pass products actually work? I would hate to spend the money and find out it is junk….
