Question 141

RTA and RTB run OSPF routing protocol, and both belong to the backbone area.
Which of the following methods can be used to advertise the directly connected route 192.168.1.0/24 of RTA to the OSPF routing domain?

A.RTA]ip route-static 192.168.1.0 24 null0 RTA-ospf-1]import-route static

B.RTA-ospf-1]import-route static

C.RTA-ospf-1]import-route direct

D.RTA-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255

Question 142

Which of the following statements are true about the BGP aggregation function?

A.When applying BGP manual aggregation, you can use the attribute-polic- parameter to change the attributes of the aggregated routes for more flexible control.

B.BGP manual aggregation can advertise aggregated routes and specific routes at the same time, or only select specific routes to generate aggregated routes.

C.There are two types of BGP aggregation: automatic aggregation and manual aggregation.

D.Since BGP supports CIDR, BGP auto-aggregation can automatically aggregate the routes existing in the routing table into routes with natural masks.

Question 143

The PBR configuration of a router is known as follows:
polic-based-route pbr_a permit node 10
if-match acl 3000
if-match packet-length 101 1000
apploutput-interface serial 2/0
Assuming that the strategy has been successfully applied, how will the relevant data flow on the router be forwarded?

A.Messages with a message length of 101~1000 bytes will be forwarded according to policy routing

B.In the data stream matching Alc3000, the message with the message length of 101~1000 bytes will not be forwarded according to the policy routing

C.Data streams matching Alc3000 and packets with a packet length of 1000 bytes or more will not be forwarded according to policy routing

D.Data streams matching Alc3000 will be forwarded according to policy routing
