QUESTION 39

Company A and company B have merged and are currently planning to combine their network backbones. All 18 of company A’s routers run OSPF, but company B’s hardware only supports RIPv2. You need to monitor both networks from a single NMS. Which solution in volves the fewest configuration steps to meet these monitoring requirements?

 

A.

move to static routing for all routers

B.

change the routing protocol on company A’s routers to RIP

C.

use router redistribution

D.

configure company A’s routers to run RIP along with OSPF

snmp-server host 192.168.15.4 private

 

access-list 60deny 192.168.12.0 255.255.240.0

 

access-list 60 permit snmp 192.168.15.4

 

The network management system (NMS) IP address is 192.168.15.4, and it is receiving SNMP traps from the router, but it is not able to poll the router.

 

Why is the NMS unable to poll the router?

 

A.

SNMP is not enabled on the router.

B.

No public community string is configured.
