Q11. - (Topic 3) 

At which layer of the OSI model does PPP perform? 

A. Layer 2 

B. Layer 3 

C. Layer 4 

D. Layer 5 

Answer:

Explanation: 

Point-to-Point Protocol (PPP) is a data link protocol commonly used in establishing a direct connection between two networking nodes. It can provide connection authentication, transmission encryption (using ECP, RFC 1968), and compression. 


Q12. - (Topic 2) 

Which parameter would you tune to affect the selection of a static route as a backup, when a dynamic protocol is also being used? 

A. hop count 

B. administrative distance 

C. link bandwidth 

D. link delay 

E. link cost 

Answer:

Explanation: 

What Is Administrative Distance? 

http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094195.shtml 

Administrative distance is the feature that routers use in order to select the best path. Administrative distance defines the reliability of a routing protocol. Each routing protocol is prioritized in order of most to least reliable (believable) with the help of an administrative distance value. Lowest Administrative distance will be chosen first. 


Q13. - (Topic 1) 

Which three of these statements regarding 802.1Q trunking are correct? (Choose three.) 

A. 802.1Q native VLAN frames are untagged by default. 

B. 802.1Q trunking ports can also be secure ports. 

C. 802.1Q trunks can use 10 Mb/s Ethernet interfaces. 

D. 802.1Q trunks require full-duplex, point-to-point connectivity. 

E. 802.1Q trunks should have native VLANs that are the same at both ends. 

Answer: A,C,E

Q14. - (Topic 3) 

The command frame-relay map ip 10.121.16.8 102 broadcast was entered on the router. Which of the following statements is true concerning this command? 

A. This command should be executed from the global configuration mode. 

B. The IP address 10.121.16.8 is the local router port used to forward data. 

C. 102 is the remote DLCI that will receive the information. 

D. This command is required for all Frame Relay configurations. 

E. The broadcast option allows packets, such as RIP updates, to be forwarded across the PVC. 

Answer:

Explanation: 

The command frame-relay map ip 10.121.16.8 102 broadcast means to map the remote IP 

10.121.16.8 to the local DLCI 102. When the “broadcast” keyword is included, it turns Frame Relay network as a broadcast network, which can forward broadcasts. 


Q15. - (Topic 2) 

Refer to Exhibit: 

The internetwork infrastructure of company XYZ consists of a single OSPF area as shown in the graphic. There is concern that a lack of router resources is impeding internetwork performance. As part of examining the router resources, the OSPF DRs need to be known. All the router OSPF priorities are at the default and the router IDs are shown with each router. Which routers are likely to have been elected as DR? (Choose two.) 

A. Corp-1 

B. Corp-2 

C. Corp-3 

D. Corp-4 

E. Branch-1 

F. Branch-2 

Answer: D,F 

Explanation: There are 2 segments on the topology above which are separated by Corp-3 router. Each segment will have a DR so we have 2 DRs. 

To select which router will become DR they will compare their router-IDs. The router with highest (best) router-ID will become DR. The router-ID is chosen in the order below: 

The highest IP address assigned to a loopback (logical) interface. 

If a loopback interface is not defined, the highest IP address of all active router’s physical interfaces will be chosen. 

In this question, the IP addresses of loopback interfaces are not mentioned so we will consider IP addresses of all active router’s physical interfaces. Router Corp-4 (10.1.40.40) 

& Branch-2 (10.2.20.20) have highest “active” IP addresses so they will become DRs. 


Q16. - (Topic 3) 

Which feature does PPP use to encapsulate multiple protocols? 

A. NCP 

B. LCP 

C. IPCP 

D. IPXP 

Answer:

Explanation: 

PPP permits multiple network layer protocols to operate on the same communication link. For every network layer protocol used, a separate Network Control Protocol (NCP) is provided in order to encapsulate and negotiate options for the multiple network layer protocols. It negotiates network-layer information, e.g. network address or compression options, after the connection has been established 


Q17. - (Topic 3) 

Refer to the exhibit. 

A network associate has configured OSPF with the command: City(config-router)# network 192.168.12.64 0.0.0.63 area 0 After completing the configuration, the associate discovers that not all the interfaces are participating in OSPF. Which three of the interfaces shown in the exhibit will participate in OSPF according to this configuration statement? (Choose three.) 

A. FastEthernet0 /0 

B. FastEthernet0 /1 

C. Serial0/0 

D. Serial0/1.102 

E. Serial0/1.103 

F. Serial0/1.104 

Answer: B,C,D 

Explanation: 

The “network 192.168.12.64 0.0.0.63 equals to network 192.168.12.64/26. This network has:Increment: 64 (/26= 1111 1111.1111 1111.1111 1111.1100 0000)Network address: 

192.168.12.64 Broadcast address: 192.168.12.127Therefore all interface in the range of this network will join OSPF - B C D are correct. 


Q18. - (Topic 3) 

What occurs on a Frame Relay network when the CIR is exceeded? 

A. All TCP traffic is marked discard eligible. 

B. All UDP traffic is marked discard eligible and a BECN is sent. 

C. All TCP traffic is marked discard eligible and a BECN is sent. 

D. All traffic exceeding the CIR is marked discard eligible. 

Answer:

Explanation: 

Committed information rate (CIR): The minimum guaranteed data transfer rate agreed to by the Frame Relay switch. Frames that are sent in excess of the CIR are marked as discard eligible (DE) which means they can be dropped if the congestion occurs within the Frame Relay network. Note: In the Frame Relay frame format, there is a bit called Discard eligible (DE) bit that is used to identify frames that are first to be dropped when the CIR is exceeded. 


Q19. - (Topic 3) 

What does the frame-relay interface-dlci command configure? 

A. local DLCI on the subinterface 

B. remote DLCI on the main interface 

C. remote DCLI on the subinterface 

D. local DLCI on the main interface 

Answer:

Explanation: 

Frame Relay for ICND Exam http://www.ciscopress.com/articles/article.asp?p=100603&seqNum=3 

To assign a data-link connection identifier (DLCI) to a specified Frame Relay subinterface on the router or access server, or to assign a specific permanent virtual circuit (PVC) to a DLCI, or to apply a virtual template configuration for a PPP session, use the frame-relay interface-dlci interface configuration command Example 4-23 Example of frame-relay interface-dlci Command and the Output of show frame-relay map R4(config)#interface s1/2.403 point-to-point R4(config-subif)#frame-relay interface-dlci ? <16-1007> Define a switched or locally terminated DLCI R4(config-subif)#frame-relay interface-dlci 403 ? cisco Use CISCO Encapsulation ietf Use RFC1490/RFC2427 Encapsulation

Q20. - (Topic 2) 

Refer to the exhibit. 

From R1, a network administrator is able to ping the serial interface of R2 but, unable to ping any of the subnets attached to RouterB. Based on the partial outputs in the exhibit, what could be the problem? 

A. EIGRP does not support VLSM. 

B. The EIGRP network statements are incorrectly configured. 

C. The IP addressing on the serial interface of RouterA is incorrect. 

D. The routing protocol has summarized on the classful boundary. 

E. EIGRP has been configured with an invalid autonomous system number. 

Answer:

Explanation: 

CCNA - EIGRP Common Question Reference: 

http://www.orbitco-ccna-pastquestions.com/CCNA---EIGRP-Common-Question.php 

Explanation: 

If you look carefully at the R2 ip route, you will discover that the R2 does not learn any network from R1; this is because the routing protocol used here (EIGRP) performs auto summary when advertising routes to peers across a network. So in this case the address 172.17.0.0/16 is a summarized address. If the router was configured with no auto summary command, R2 LAN addresses would have been advertised and reached.
