Q1. – (Topic 2) 

Which type of EIGRP route entry describes a feasible successor? 

A. a backup route, stored in the routing table 

B. a primary route, stored in the routing table 

C. a backup route, stored in the topology table 

D. a primary route, stored in the topology table 

Answer:

Explanation: 

http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080093f07.shtml 

Feasible Successors A destination entry is moved from the topology table to the routing table when there is a feasible successor. All minimum cost paths to the destination form a set. From this set, the neighbors that have an advertised metric less than the current routing table metric are considered feasible successors. Feasible successors are viewed by a router as neighbors that are downstream with respect to the destination. These neighbors and the associated metrics are placed in the forwarding table. When a neighbor changes the metric it has been advertising or a topology change occurs in the network, the set of feasible successors may have to be re-evaluated. However, this is not categorized as a route recomputation. Feasible successor is a route whose Advertised Distance (AD) is less than the Feasible Distance (FD) of the current best path. A feasible successor is a backup route, which is not stored in the routing table but, stored in the topology table. 

Q2. – (Topic 2) 

Refer to the exhibit. 

A packet with a source IP address of 192.168.2.4 and a destination IP address of 10.1.1.4 arrives at the AcmeB router. What action does the router take? 

A. forwards the received packet out the Serial0/0 interface 

B. forwards a packet containing an EIGRP advertisement out the Serial0/1 interface 

C. forwards a packet containing an ICMP message out the FastEthemet0/0 interface 

D. forwards a packet containing an ARP request out the FastEthemet0/1 interface 

Answer: C Explanation: 

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

Looking at the output above, there is no IP route for 10.1.1.4 address on AcmeB routing table. If the router can no find a specific path in its routing table to a particular route,( In this case no path is found so AcmeB) the router will inform the source host with an ICMP message that the destination is unreachable and this will be through the same interface it has received the packet (interface Fa0/0 network 192.168.3.0/28 from the exhibit).

Q3. – (Topic 3) 

What can be done to Frame Relay to resolve split-horizon issues?(Choose two.) 

A. Disable Inverse ARP. 

B. Create a full-mesh topology. 

C. Develop multipoint subinterfaces. 

D. Configure point-to-point subinterfaces. 

E. Remove the broadcast keyword from the frame-relay map command. 

Answer: B,D 

Explanation: 

IP split horizon checking is disabled by default for Frame Relay encapsulation to allow routing updates to go in and out of the same interface. An exception is the Enhanced Interior Gateway Routing Protocol (EIGRP) for which split horizon must be explicitly disabled. Certain protocols such as AppleTalk, transparent bridging, and Internetwork Packet Exchange (IPX) cannot be supported on partially meshed networks because they require split horizon to be enabled (a packet received on an interface cannot be transmitted over the same interface, even if the packet is received and transmitted on different virtual circuits). Configuring Frame Relay subinterfaces ensures that a single physical interface is treated as multiple virtual interfaces. This capability allows you to overcome split horizon rules so packets received on one virtual interface can be forwarded to another virtual interface, even if they are configured on the same physical interface. 

Q4. – (Topic 3) 

Which two statements about using the CHAP authentication mechanism in a PPP link are true? (Choose two.) 

A. CHAP uses a two-way handshake. 

B. CHAP uses a three-way handshake. 

C. CHAP authentication periodically occurs after link establishment. 

D. CHAP authentication passwords are sent in plaintext. 

E. CHAP authentication is performed only upon link establishment. 

F. CHAP has no protection from playback attacks. 

Answer: B,C 

Explanation: 

Understanding and Configuring PPP CHAP Authentication http://www.cisco.com/en/US/tech/tk713/tk507/technologies_tech_note09186a00800b4131. shtml 

One-Way and Two-Way Authentication CHAP is defined as a one-way authentication method. However, you use CHAP in both directions to create a two-way authentication. Hence, with two-way CHAP, a separate three-way handshake is initiated by each side. In the Cisco CHAP implementation, by default, the called party must authenticate the calling party (unless authentication is completely turned off). Therefore, a one-way authentication initiated by the called party is the minimum possible authentication. However, the calling party can also verify the identity of the called party, and this results in a two-way authentication. One-way authentication is often required when you connect to non-Cisco devices. 

Q5. – (Topic 3) 

What is the result of issuing the frame-relay map ip 192.168.1.2 202 broadcast command? 

A. defines the destination IP address that is used in all broadcast packets on DCLI 202 

B. defines the source IP address that is used in all broadcast packets on DCLI 202 

C. defines the DLCI on which packets from the 192.168.1.2 IP address are received 

D. defines the DLCI that is used for all packets that are sent to the 192.168.1.2 IP address 

Answer:

Explanation: 

Frame-relay map ip 192.168.1.2 202 command statically defines a mapping between a network layer address and a DLCI. The broadcast option allows multicast and broadcast packets to flow across the link. The command frame-relay map ip 192.168.1.2 202 broadcast means to mapping the distal IP 192.168.1.2 202 to the local DLCI . When the “broadcast” keyword is included, it turns Frame Relay network as a broadcast network, which can forward broadcasts. http://www.cisco.com/en/US/docs/ios/wan/command/reference/wan_f2.html#wp1012264 

Q6. – (Topic 1) 

Refer to the exhibit. 

Given the output shown from this Cisco Catalyst 2950, what is the reason that interface FastEthernet 0/10 is not the root port for VLAN 2? 

A. This switch has more than one interface connected to the root network segment in VLAN 2. 

B. This switch is running RSTP while the elected designated switch is running 802.1d Spanning Tree. 

C. This switch interface has a higher path cost to the root bridge than another in the topology. 

D. This switch has a lower bridge ID for VLAN 2 than the elected designated switch. 

Answer:

Explanation: These four parameters are examined in order to make root bridge , root port , designated port. Other switch has lowest Sending Bridge ID or Sending Port ID so vlan 2 is not the root port. 

1. A lower Root Bridge ID2. A lower path cost to the Root3. A lower Sending Bridge ID4. A lower Sending Port ID 

Q7. – (Topic 2) 

Refer to the exhibit. 

Which two statements are true about the loopback address that is configured on RouterB? (Choose two.) 

A. It ensures that data will be forwarded by RouterB. 

B. It provides stability for the OSPF process on RouterB. 

C. It specifies that the router ID for RouterB should be 10.0.0.1. 

D. It decreases the metric for routes that are advertised from RouterB. 

E. It indicates that RouterB should be elected the DR for the LAN. 

Answer: B,C 

Explanation: A loopback interface never comes down even if the link is broken so it provides stability for the OSPF process (for example we use that loopback interface as the router-id) – B is correct. 

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. 

-The loopback interface will be chosen as the router ID of RouterB – C is correct. 

Q8. DRAG DROP – (Topic 2) 

Answer: 

Explanation: 

+ holddown timer: prevents a router from improperly reinstating a route from a regular routing update 

+ split horizon: prevents information about a route from being sent in the direction from which the route was learned 

+ defining a maximum: prevents invalid updates from looping the internetwork indefinitely 

+ route poisoning: causes a routing protocol to advertise an infinite metric for a failed route 

+ triggered update: decreases convergence time by immediately sending route information in response to a topology change 

Q9. – (Topic 3) 

What is the advantage of using a multipoint interface instead of point-to-point subinterfaces when configuring a Frame Relay hub in a hub-and-spoke topology? 

A. It avoids split-horizon issues with distance vector routing protocols. 

B. IP addresses can be conserved if VLSM is not being used for subnetting. 

C. A multipoint interface offers greater security compared to point-to-point subinterface configurations. 

D. The multiple IP network addresses required for a multipoint interface provide greater addressing flexibility over point-to-point configurations. 

Answer:

Explanation: 

You do not have to assign a separate subnet per sub-interface .if you're using a Class A network (10.x.x.x/8), you blow the whole network on a few connections (if you used VLSM, you could use a better mask, limit the addresses used). if you used 10.0.0.0/8, you would not be assigning the entire /8 to a single network. You would select a subnet mask for the network and then, you would have to use that mask with all subnets of the network. So if you chose a /24 mask, that would mean that you would have to use a /24 mask for even point-to-point links. 

Q10. – (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
