Q11. - (Topic 2) 

What can cause two OSPF neighbors to be stuck in the EXSTART state? 

A. There is a low bandwidth connection between neighbors. 

B. The neighbors have different MTU settings. 

C. The OSPF interfaces are in a passive state. 

D. There is only layer one connectivity between neighbors. 

Answer:

Explanation: 

Neighbors Stuck in Exstart/Exchange State The problem occurs most frequently when attempting to run OSPF between a Cisco router and another vendor's router. The problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces don't match. If the router with the higher MTU sends a packet larger that the MTU set on the neighboring router, the neighboring router ignores the packet.0 When this problem occurs, the output of the show ip ospf neighbor command displays output similar that shown below: router-6# show ip ospf neighbor

Q12. - (Topic 2) 

Which two are advantages of static routing when compared to dynamic routing? (Choose two.) 

A. Configuration complexity decreases as network size increases. 

B. Security increases because only the network administrator may change the routing table. 

C. Route summarization is computed automatically by the router. 

D. Routing tables adapt automatically to topology changes. 

E. An efficient algorithm is used to build routing tables, using automatic updates. 

F. Routing updates are automatically sent to neighbors. 

G. Routing traffic load is reduced when used in stub network links. 

Answer: B,G 

Explanation: 

When reading (or being lectured about) all the glorious details of dynamic routing protocols, it's hard not to come away with the impression that dynamic routing is always better than static routing. It's important to keep in mind that the primary duty of a dynamic routing protocol is to automatically detect and adapt to topological changes in the internetwork. The price of this "automation" is paid in bandwidth, security, and maybe queue space, in memory, and in processing time. A frequent objection to static routing is that it is hard to administer. This criticism may be true of medium to large topologies with many alternative routes, but it is certainly not true of small internetworks with few or no alternative routes.

Q13. - (Topic 1) 

Refer to the exhibit. 

Why has this switch not been elected the root bridge for VLAN1? 

A. It has more than one interface that is connected to the root network segment. 

B. It is running RSTP while the elected root bridge is running 802.1d spanning tree. 

C. It has a higher MAC address than the elected root bridge. 

D. It has a higher bridge ID than the elected root bridge. 

Answer:

Explanation: 

http://www.cisco.com/en/US/tech/tk389/tk621/technologies_tech_note09186a008009482f.s html When a switch receives a BPDU, it first compares priority, the lower number wins. If a tie, compare MAC, the smaller one wins. Here Switch has 32769 priority which is greater than 20481 so switch will not elect for root bridge. It says the bridge priority for Switch is 32769, and the root priority is 20481. Which means that some other switch has the lower priority and won the election for VLAN 1. 


Q14. - (Topic 2) 

Refer to the exhibit. 

Which three EIGRP routes will be present in the router R4's routing table? (Choose three.) 

A. 172.16.1.0/24 

B. 10.1.10.0/30 

C. 10.0.0.0/8 

D. 10.1.11.0/30 

E. 172.16.0.0/16 

F. 192.168.1.0/24 

Answer: C,E,F 

Explanation: 

EIGRP performs an auto-summarization each time it crosses a border between two different major networks, so when R2 advertises the routes to R4 it will advertise only the summarized routes of 10.0.0.0/8 and 172.16.0.0/16, along with the 192.168.1.0/24 route coming from R3. 


Q15. - (Topic 2) 

Refer to the exhibit. 

The network associate is configuring OSPF on the Core router. All the connections to the branches should be participating in OSPF. The link to the ISP should NOT participate in OSPF and should only be advertised as the default route. What set of commands will properly configure the Core router? 

A. Core(config-router)# default-information originate Core(config-router)# network 10.0.0.0 0.255.255.255 area 0 Core(config-router)# exit Core(config)# ip route 0.0.0.0 0.0.0.0 10.10.2.14 

B. Core(config-router)# default-information originate Core(config-router)# network 10.10.2.13 0.0.0.242 area 0 Core(config-router)# exit Core(config)# ip route 0.0.0.0 0.0.0.0 10.10.2.14 

C. Core(config-router)# default-information originate Core(config-router)# network 10.10.2.16 0.0.0.15 area 0 Core(config-router)# exit Core(config)# ip route 0.0.0.0 0.0.0.0 10.10.2.14 

D. Core(config-router)# default-information originate Core(config-router)# network 10.10.2.32 0.0.0.31 area 0 Core(config-router)# exit Core(config)# ip route 0.0.0.0 0.0.0.0 10.10.2.14 

Answer:

Explanation: 

There are two ways to inject a default route into a normal area.1. If the ASBR already has the default route in its routing table, you can advertise theexisting 0.0.0.0/0 into the OSPF domain with the default-information originate router configuration command.2. If the ASBR doesn’t have a default route, you can add the keyword always to the default-information originate command (default-information originate always).This command will advertise a default route into the OSPF domain, regardless of whether it has a route to 0.0.0.0. Another benefit of adding always keyword is that it can add stability to the internetwork. For example, if the ASBR is learning a default route from another routing domain such as RIP and this route is flapping, then without the always keyword, each time the route flaps, the ASBR will send a new Type 5 LSA into the OSPF domain causing some instability inside the OSPF domain. With the always keyword, the ASBR will advertise the default inside the OSPF domain always, In the example shown here, only choice C is correct as the wildcard mask correctly specifies the 10.10.2.16 0.0.0.15 networks, which include all IP addresses in the 10.10.2.16-10.10.2.31 range. In this question we were told that the ISP link should NOT be configured for OSPF, making choice A incorrect. http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a00801 ec9f0.shtml 


Q16. - (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. 


Q17. - (Topic 2) 

Refer to the exhibit. 

What information about the interfaces on the Main_Campus router is true? 

A. The LAN interfaces are configured on different subnets. 

B. Interface FastEthernet 0/0 is configured as a trunk. 

C. The Layer 2 protocol of interface Serial 0/1 is NOT operational. 

D. The router is a modular router with five FastEthernet interfaces. 

E. Interface FastEthernet 0/0 is administratively deactivated. 

Answer:

Explanation: 

Interface fa0/0 breaks into sub-interfaces and Main_Campus router is connected with switch via fa0/0 .Subinterfaces configured with different subnet masks so the same switch has multiple vlans and allows communication between these VLAN's. For routing and inter-vlan we need to configure a trunk port. So B will be the correct answer. 


Q18. - (Topic 3) 

What are two characteristics of Frame Relay point-to-point subinterfaces? (Choose two.) 

A. They create split-horizon issues. 

B. They require a unique subnet within a routing domain. 

C. They emulate leased lines. 

D. They are ideal for full-mesh topologies. 

E. They require the use of NBMA options when using OSPF. 

Answer: B,C 

Explanation: http://www.ciscopress.com/articles/article.asp?p=170741&seqNum=5 

Configuring Frame Relay Subinterfaces On partially meshed Frame Relay networks, the problem of split horizon can be overcome by using Frame Relay subinterfaces. Frame Relay provides a mechanism to allow a physical interface to be partitioned into multiple virtual interfaces. In a similar way, using subinterfaces allows a partially meshed network to be divided into a number of smaller, fully meshed point-to-point networks. Generally, each point-to-point subnetwork is assigned a unique network address. This allows packets received on one physical interface to be sent out from the same physical interface, albeit forwarded on VCs in different subinterfaces. There are two types of subinterfaces supported by Cisco routers: point-to-point and multipoint subinterfaces. 


Q19. - (Topic 3) 

What is the purpose of LCP? 

A. to perform authentication 

B. to negotiate control options 

C. to encapsulate multiple protocols 

D. to specify asynchronous versus synchronous 

Answer:

Explanation: 

In order to be sufficiently versatile to be portable to a wide variety of environments, PPP provides a Link Control Protocol (LCP). The LCP is used to automatically agree upon the encapsulation format options, handle varying limits on sizes of packets, detect a looped-back link and other common misconfiguration errors, and terminate the link. Other optional facilities provided are authentication of the identity of its peer on the link, and determination when a link is functioning properly and when it is failing.

Q20. - (Topic 2) 

Refer to the exhibit. 

Based on the exhibited routing table, how will packets from a host within the 192.168.10.192/26 LAN be forwarded to 192.168.10.1? 

A. The router will forward packets from R3 to R2 to R1. 

B. The router will forward packets from R3 to R1 to R2. 

C. The router will forward packets from R3 to R2 to R1 AND from R3 to R1. 

D. The router will forward packets from R3 to R1. 

Answer:

Explanation: 

From the routing table we learn that network 192.168.10.0/30 is learned via 2 equal- cost paths (192.168.10.9 &192.168.10.5) - traffic to this network will be load-balanced.
