R2 has a locally originated prefix 192.168.130.0/24 and has these configurations:

What is the result when the route-map OUT command is applied toward an eBGP neighbor R1 (1.1.1.1) by using the neighbor 1.1.1.1 route-map OUT out command?

 


A.

R1 sees 192.168.130.0/24 as two AS hops away instead of one AS hop away.


B.

R1 does not accept any routes other than 192.168.130.0/24


C.

R1 does not forward traffic that is destined for 192.168.30.0/24


D.

Network 192.168.130.0/24 is not allowed in the R1 table

Refer to the exhibit.

An engineer configures a static route on a router, but when the engineer checks the route to the destination, a different next hop is chosen. What is the reason for this?


A.

Dynamic routing protocols always have priority over static routes.


B.

The metric of the OSPF route is lower than the metric of the static route.


C.

The configured AD for the static route is higher than the AD of OSPF.


D.

The syntax of the static route is not valid, so the route is not considered.





C.
  

The configured AD for the static route is higher than the AD of OSPF.



Refer to the exhibit.

A junior engineer updated a branch router configuration. Immediately after the change, the engineer receives calls from the help desk that branch personnel cannot reach any network destinations. Which configuration restores service and continues to block 10.1.1.100/32?

 


A.

route-map FILTER-IN deny 5


B.

ip prefix-list 102 seq 15 permit 0.0.0.0/32 le 32


C.

ip prefix-list 102 seq 5 permit 0.0.0.0/32 le 32


D.

route-map FILTER-IN permit 20





D.

Refer to the exhibit.

R2 is a route reflector, and R1 and R3 are route reflector clients. The route reflector learns the route to 172.16.25.0/24 from R1, but it does not advertise to R3. What is the reason the route is not advertised?

 


A.

R2 does not have a route to the next hop, so R2 does not advertise the prefix to other clients.


B.

Route reflector setup requires full IBGP mesh between the routers.


C.

In route reflector setup, only classful prefixes are advertised to other clients.


D.

In route reflector setups, prefixes are not advertised from one client to another.





A.
  

R2 does not have a route to the next hop, so R2 does not advertise the prefix to other clients.

B.

Configure the DHCP lease time to a smaller value


C.

Configure the DHCP lease time to a bigger value


D.

Add the network 192.168.2.0 255.255.255.0 command to the DHCP pool
