QUESTION NO:30

Refer to the exhibit. Routing updates for the 192.168.1.0 network are being received from all three neighbors. Which statement is correct regarding the result of the configuration shown?

!

router bgp 65001

neighbor 172.16.1.1 remote-as 65001

neighbor 172.26.1.1 remote-as 65555

neighbor 172.26.1.1 route-map local_pref in

neighbor 172.30.1.1 remote-as 65510

!

route-map local_pref permit 10

match ip address 20

set local-preference 200

!

access-list 20 permit 192.168.1.0 0.0.0.255

!

A. The router will prefer the next hop of 172.16.1.1 for packets destined for the 192.168.1.0 network.

B. The router will prefer the next hop of 172.26.1.1 for packets destined for the 192.168.1.0 network.

C. The router will advertise the 192.168.1.0 network only to 172.30.1.1.

D. The router will advertise the 192.168.1.0 network only to 172.26.1.1.

E. The router will prefer the next hop of 172.26.1.1 for packets except those destined for the

192.168.1.0 network.

Correct Answer: B Explanation

Explanation/Reference:

The local-preference of the next hop 172.26.1.1 is set to 200, which is higher than the default value (100) so this path is preferred for packets destined to the 192.168.1.0 network.

QUESTION NO:21

Refer to the partial configurations in the exhibit. What address is utilized for DR and BDR identification on Router1?

A. the serial 1/1 address

B. the serial 2/0 address

C. a randomly generated internal address

D. the configured router-id address

Correct Answer: D Explanation

Explanation/Reference:

In OSPFv3 and OSPF version 2, the router uses the 32-bit IPv4 address to select the router ID for an OSPF process. The router ID selection process for OSPFv3 is described below (same as OSPF version 2):

1.

The router ID is used if explicitly configured with the router-id command.

2.

Otherwise, the highest IPv4 loopback address is used.

3.

Otherwise, the highest active IPv4 address.

4.

Otherwise, the router ID must be explicitly configured.

In this case the router ID 10.1.1.3 is explicitly configured

QUESTION NO:2

Refer to the exhibit. The DHCP configuration that is shown is configured on a Cisco router. Which statement is true?

ip dhcp pool 1

network 172.16.1.0/24

netbios-name-server 172.16.1.103

default-router 172.16.1.100 172.16.1.101

netbios-name-server 172.16.2.103

default-router 172.16.2.100 172.16.2.101

A. The router will distribute IP addresses from pool 1 until its addresses are exhausted. Then the router will begin distributing addresses from pool 2.

B. The router will choose which pool to use based upon the interface the DHCP request was received on.

C. The configuration is invalid because the DHCP options are global configuration commands.

D. The configuration is incomplete until the DHCP pools are bound to the appropriate interface or interfaces.

QUESTION NO:6

A network administrator is troubleshooting a redistribution of RIP routes into OSPF. Given the exhibited commands, which statement is true?

router rip

network 10.0.0.0

!

router ospf 5

network 172.10.0.0 0.0.255.255 area 0

redistribute rip

A. Redistributed routes will have an external type of 1 and a metric of 1.

B. Redistributed routes will have an external type of 2 and a metric of 20.

C. Redistributed routes will maintain their original OSPF routing metric.

D. Redistributed routes will have a default metric of 0 and will be treated as reachable and advertised.

E. Redistributed routes will have a default metric of 0 but will be treated as unreachable and not advertised.

Correct Answer: B Explanation

Explanation/Reference:

By default, all routes redistributed into OSPF will be tagged as external type 2 (E2) with a metric of 20, except for BGP routes (with a metric of 1).

Note: The cost of a type 2 route is always the external cost, irrespective of the interior cost to reach that route. A type 1 cost is the addition of the external cost and the internal cost used to reach that route.
