Question No: 12

Router A and Router B are configured with IPv6 addressing and basic routing capabilities using OSPFv3. The networks that are advertised from Router A do not show up in Router B's routing table. After debugging IPv6 packets, the message "not a router" is found in the output. Why is the routing information not being learned by Router B?

A. OSPFv3 timers were adjusted for fast convergence.

B. The networks were not advertised properly under the OSPFv3 process.

C. An IPv6 traffic filter is blocking the networks from being learned via the Router B interface that is connected to Router A.

D. IPv6 unicast routing is not enabled on Router A or Router B.

Answer: D

Question No: 18

How is network layer addressing accomplished in the OSI protocol suite?

A. Internet Protocol address

B. Media Access Control address

C. Packet Layer Protocol address

D. Network Service Access Point address

E. Authority and Format Identifier address

Answer: D

Explanation:

OSI network-layer addressing is implemented by using two types of hierarchical addresses: network service access-point addresses and network-entity titles.

A network service-access point (NSAP) is a conceptual point on the boundary between the network and the transport layers. The NSAP is the location at which OSI network services are provided to the transport layer. Each transport-layer entity is assigned a single NSAP, which is individually addressed in an OSI internetwork using NSAP addresses.

Question No: 19

Which cisco Express Forwarding component maintains Layer 2 addressing information?

A. dCEF

B. adjacency table.

C. FIB

D. fast switching

E. RIB

Answer: B

Explanation: Adjacency TablesNodes in the network are said to be adjacent if they can reach each other with a single hop across a link layer. In addition to the FIB, CEF uses adjacency tables to prepend Layer 2 addressing information. The adjacency table maintains Layer 2 next-hop addresses for all FIB entries. http://www.cisco.com/c/en/us/td/docs/ios/12_2/switch/configuration/guide/fswtch_c/xcfcef.ht ml

Question No: 20

Router RTA is configured as follows:

RTA (config)#router rip

RTA(config-router)#network 10.0.0.0

RTA(config-router)#distribute-list 44 in interface BRIO RTA(config-router)#exit

RTA(config)#access-list 44 deny 172.16.1.0 0.0.0.255 RTA(config)#access-list 44 permit any

What are the effects of this RIP configuration on router RTA? (Choose two)

A. no routing updates will be sent from router RTA on interface BRIO to router RTX

B. router RTA will not advertise the 10.0.0.0 network to router RTX

C. the route to network 172.16.1.0 will not be entered into the routing table on router RTA

D. user traffic from the 172.16.1.0 network is denied by access-list 44

E. the routing table on router RTA will be updated with the route to router RTW

Answer: C,E

Explanation:

Distribute list are used to filter routing updates and they are based on access lists. In this case, an access list of 44 was created to deny the route from network 172.16.1.0/24 so this route will not be entered into the routing table of RTA. But the route from RTW can be entered because it is not filtered by the access list A and B are not correct because the distribute list is applied to the inbound direction of interface BRI0 so outgoing routing updated will not be filtered.

Distribute list just filters routing updates so user traffic from network 172.16.1.0 will not be denied.

Question No: 21

Which set of actions does a network engineer perform to set the IPv6 address of a DHCP relay server at the VLAN interface level?

A. Enter the VLAN interface configuration mode and define the IPv6 address of a DHCP relay server

B. Enter the global configuration mode and enable the IPv6 DHCP relay

C. Enter the global configuration mode, enable IPv6 DHCP relay from interface configuration mode and define the IPv6 address of a DHCP relay server

D. Enter the VLAN interface configuration mode, enable IPv6 DHCP relay, and define the IPv6 address of a DHCP relay server

Answer: D

Explanation: You can accept DHCP requests from clients on the associated context or VLAN interface and enable the DHCP relay agent by using the ipv6 dhcp relay enable command (for IPv6) or the ip dhcp relay enable command (for IPv4). The DHCP relay starts forwarding packets to the DHCP server address specified in the ipv6 dhcp relay server command or the ip dhcp relay server command for the associated context or VLAN interface.
