1. Topic 1, Exam Pool A

What is the maximum number of routers that each OSPF area (including the backbone) should contain?

2. What is the maximum number of neighbors that a router should have in an OSPF area?

3. Which technology allows multiple instances of a routing table to coexist on the same router simultaneously?

4. Which first-hop redundancy protocol that was designed by Cisco allows packet load sharing among groups of redundant routers?

5. Which routing protocol provides the fastest convergence and greatest flexibility within a campus environment?

6. A network manager wants to securely connect a new remote site to the existing headquarters site using a VPN technology that meets security requirements.

Which VPN technology should be used?

7. Which type of connectivity is required for VPLS?

8. Which protocol should be run on the LAN side of two edge routers (that are terminating primary and backup WAN circuits) to provide quick failover in case of primary WAN circuit failure?

9. Which protocol is best when there are circuit connections with two different ISPs in a multihoming scenario?

10. Private lines make use of which connection type based on cell switching?

11. Refer to the exhibit.

Which functionality must be enabled on router A to connect two networks for translating private addresses into "legal" public addresses on a one-for-one basis?

12. Which technology fulfills these requirements?
