NEW QUESTION 29
Which statements are true about EIGRP successor routes? (Choose two.)
- A. Successor routes are stored in the neighbor table following the discovery process.
- B. A successor route may be backed up by a feasible successor route.
- C. Successor routes are saved in the topology table to be used if the primary route fails.
- D. Successor routes are flagged as 'active' in the routing table.
- E. A successor route is used by EIGRP to forward traffic to a destination.
Answer: B,E
Explanation:
Introduction to EIGRP 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.
NEW QUESTION 30
Which command allows you to verify the encapsulation type (CISCO or IETF) for a Frame Relay link?

NEW QUESTION 31 
R1 is configured with the default configuration of OSPF.
From the following list of IP addresses configured on R1, which address will the OSPF process select as the router ID?
- A. 192.168.0.1
- B. 172.16.2.225
- C. 172.16.2.1
- D. 172.16.1.1
Answer: A
Explanation:
Explanation
The Router ID (RID) is an IP address used to identify the router and is chosen using the following sequence:
+
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 router ID can be manually assigned
In this case, because a loopback interface is not configured so the highest active IP address 192.168.0.1 is chosen as the router ID.
NEW QUESTION 32

- B. exstart state > loading state > exchange state > full state
- C. exstart state > full state > loading state > exchange state
- D. loading state > exchange state > full state > exstart state
Answer: A
Explanation:

NEW QUESTION 41
In the Frame Relay network, which IP addresses would be assigned to the interfaces with point-topoint PVCs?
- A. DLCI 16 192.168.10.1 /24 DLCI 17 192.168.11.1/24 DLCI 99 192.168.12.1/24
DLCI 28 192.168.13.1/24 - B. DLCI 16 192.168.10.1/24 DLCI 17 192.168.11.1/24 DLCI 99 192.168.10.2/24 DLCI 28 192.168.11.2/24
- C. DLCI 16 192.168.10.1/24 DLCI 17 192.168.10.1/24 DLCI 99 192.168.10.2/24 DLCI 28 192.168.10.3/24
- D. DLCI 16 192.168.10.1/24 DLCI 17 192.168.10.2/24 DLCI 99 192.168.10.3/24 DLCI 28 192.168.10.4/24
Answer: B
Explanation:
DLCI 16 and DLCI 19 need to act like a point-to-point link and will therefore need to be on the same network as will DLCI 17 and DLCI 28. With this information we can see that option "B" is the only option that has the corresponding DLCI's on the same network based on the ip addresses and subnetmask. Option "D" is incorrect because, this would put the same network on both interfaces of the R2 router. Option "A" is similar.

- F. OSPF routers discover neighbors before exchanging routing information.
Answer: B,D,F
Explanation:
Open Shortest Path First Reference:
http://docwiki.cisco.com/wiki/Open_Shortest_Path_First
Explanation:
Additional OSPF features include equal-cost, multipath routing, and routing based on upper-layer type-ofservice
(TOS) requests. TOS-based routing supports those upper-layer protocols that can specify particular
types of service. An application, for example, might specify that certain data is urgent. If OSPF has high-priority
links at its disposal, these can be used to transport the urgent datagram.
OSPF supports one or more metrics. If only one metric is used, it is considered to be arbitrary, and TOS is not supported. If more than one metric is used, TOS is optionally supported through the use of a separate metric (and, therefore, a separate routing table) for each of the eight combinations created by the three IP TOS bits (the delay, throughput, and reliability bits). For example, if the IP TOS bits specify low delay, low throughput, and high reliability, OSPF calculates routes to all destinations based on this TOS designation. IP subnet masks are included with each advertised destination, enabling variable-length subnet masks. With variable-length subnet masks, an IP network can be broken into many subnets of various sizes. This provides network administrators with extra network-configuration flexibility.
NEW QUESTION 45 
A static map to the S-AMER location is required. Which command should be used to create this map?
- A. frame-relay map ip 172.30.0.3 387 broadcast

- C. frame-relay map ip 172.30.0.3 230 broadcast
- D. frame-relay map ip 172.30.0.3 825 broadcast
Answer: C
Explanation:
Frame-relay map ip 172.30.0.3 230 broadcast
172.30.0.3 is S-AMER router ip address and its configure on 230 dlci value. Check "show frame-relay map " output in the diagram.

NEW QUESTION 48
Which command enables IPv6 forwarding on a Cisco router?
- A. ipv6 host
- B. ipv6 unicast-routing
- C. ipv6 local
- D. ipv6 neighbor
Answer: B
Explanation:
http://www.ciscopress.com/articles/article.asp?p=31948&seqNum=4
The first step of enabling IPv6 on a Cisco router is the activation of IPv6 traffic forwarding to forward unicast IPv6 packets between network interfaces. By default, IPv6 traffic forwarding is disabled on Cisco routers. The ipv6 unicast-routing command is used to enable the forwarding of IPv6 packets between interfaces on the router. The syntax for this command is as follows: Router(config)#ipv6 unicast-routing The ipv6 unicast-routing command is enabled on a global basis.
NEW QUESTION 49
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. Serial0/1.102
- B. FastEthernet0 /1
- C. Serial0/1.103
- D. Serial0/1.104
- E. Serial0/0
- F. FastEthernet0 /0
Answer: A,B,E
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.
