C. BGP attributes are always optional.

D. The AS path attribute indicates the autonomous systems through which the route has traversed.

Your network connections to the Internet through two different ISPs using EBGP. You must ensure that ISP1 is the primary path used for all traffic entering your network while using ISP2 as a backup path.

In this scenario, which statement is correct?

A. You should use a lower MED value on routes sent to ISP1.

B. You should assign a higher local preference on routes that you are sending to ISP1.

C. You should change the next hop for all routers sent to ISP2.

D. You should prepend your local AS number three times on routes that you are sending to ISP2.

B. Use identical link metrics where possible.

C. Use point-to-point interface types where possible.

D. Use stub areas where possible.

Click the Exhibit button.

You manage the Layer 2 network shown in the exhibit. You experience a failure on the ge-0/0/0 link between Switch-1 and Switch-2.

Which statement is correct about the expected behavior?

A. Switch-2 will remove itself from the RSTP topology

B. Switch-2's ge-0/0/2 port role and state will transition to root and forwarding

C. Switch-2 will become the root bridge for a separate RSTP topology

D. Switch-2's ge-0/0/2 port role and state will remain as designated and forwarding

Which OSPF packet type is sent when an OSPF router detects its database is stale?

A. database description

B. link-state acknowledgment

C. link-state request

D. hello

Click the Exhibit button.

Referring to the exhibit, Router-1 and Router-2 are failing to form an IS-IS adjacency.

What should you do to solve the problem?

A. Remove the overloaded statement from Router-1.

B. Change the IP subnet masks to match on the ge-0/0/2 interfaces of both routers.

C. Change the ISO areas on the lo0 interfaces to match on both routers.

D. Remove the ISO address from ge-0/0/2 on Router-1.

A. 20 bytes

B. 24 bytes

C. 28 bytes

D. 14 bytes

Click the Exhibit button.

Referring to the exhibit, the local router should have an IS-IS adjacency with a neighboring router, but the adjacency never establishes correctly.

What should you do to solve the problem?

A. Disable level 2 for the interfaces.

B. Disable level 1 for the interfaces.

C. Disable wide metrics.

D. Change the local IS-IS area ID to 49.0002.
