1.

What is the role of route preference?

It is used as a tiebreaker when the same prefix is available through multiple protocols. It is used to determine the preferred path to a given destination. It is used to select the best route between multiple equal-cost paths. It is used to select which routing table to use for forwarding.

2.

What is the default route preference value for EBGP?

20 100 170 200

3.

What is the default protocol preference for OSPF internal routes?

10 15 150 160

4.

By default, if equal-cost paths exist for the same destination, which action will the router take?

Drop half the traffic. Make a copy of the traffic and send it to both destinations. Load-balance traffic between the available paths. Randomly select one of the available paths to send traffic.

5.

Which command will display only direct routes?

show route show route inet.0 direct show ip route direct show route protocol direct

6.

When attempting to view the OSPF routes in the routing table, you issue the command show route table inet.3 but no OSPF routes are displayed. What is the problem?

The OSPF routes are located in the inet4.0 routing table. The OSPF routes are located in the inet.0 routing table. The OSPF routes are located in the inet.2 routing table. The OSPF routes are located in the inet4.3 routing table.

9.

Which statement is true about a routing table?

It contains routes learned dynamically only. It finds the best path to each destination by using a modified shortest-path-first calculation. It contains only active BGP routes. It contains all accepted routes to all destinations.
