Questions 5

Your Layer 2 network uses VLAN IDs 100 through 400 and you are required to load-balance these VLANs between two different root bridges. You are currently using the default RSTP settings and notice that all VLANs are using the same root bridge.

How do you ensure the VLANs are load-balanced between two root bridges?

A. Configure MSTP with two MSTI regions and split the VLAN range between them.

B. Configure VSTP with two VLAN groups and split the VLAN range between them.

C. Configure two RSTP instances and split the VLAN range between them.

D. Configure STP and RSTP and split the VLAN range between them.

You are troubleshooting a problem where an EBGP route is not being advertised to your local IBGP peers. You have received a 10.222.1.3/32 route from an EBGP peer as shown in the exhibit, but the route is not being advertised.

What is causing the problem?

A. The route shows as a hidden route and cannot be advertised.

B. The next hop for the route is indirect and prevents the route from being advertised.

C. The community prevents the route from being advertised.

D. The local preference value is too high for the route to be advertised.

On R1, the interface fe-0/0/1 is assigned to the default routing instance and fe-0/0/2 is assigned to a virtual

router instance named VR-1.

Referring to the exhibit, the static route 200.200.200.200/32 is missing from the routing table of the default

routing instance.

What should you do on R1 to resolve this problem?

A. Configure a static ARP entry for address 70.1.1.1.

B. Change the instance type on VR-1 to forwarding.

C. Create a RIB group to import the direct route 70.1.1.0/24 to both the default instance and the VR-1 instance.

D. Configure an import policy to import the route 200.200.200.200/32 to the VR-1 instance.

The exhibit shows the complete BGP configuration for a router. The network operator reports that both

peering sessions are up, but the router is not conducting per-flow load balancing over the connections to

these two peers.

What are two causes for this behavior? (Choose two.)

A. The forwarding-table export policy is not configured to cause per-flow load balancing.

B. The multiple-as parameter causes BGP to only choose multiple paths to different ASs, rather than multiple paths to the same AS.

C. The router has different IGP metrics to these BGP peers.

D. The BGP peers are not sending identical advertisements over the two sessions.

Click the Exhibit button.

The policy shown in the exhibit is deployed on a router and used as the only BGP export policy. The router

is sending only one BGP route to its peers. However, when you run the CLI command test policy accept-

static 0.0.0.0/0, the policy matches thousands of routes.

Which statement explains this discrepancy?

A. All policies have an implicit then accept final term.

B. The default policy for BGP is to reject all routes.

C. The default policy for the test policy command is to accept all routes.

D. The test policy command always shows all routes, regardless of whether they match the policy, when you use the 0.0.0.0/0 argument.
