When multiple routing protocols offer a route for the same prefix, what part of the router is in charge of deciding which route to make active?

• A.The routing information base (RIB)
• B.The routing table manager (RTM)
• C.The forwarding information base (FIB)
• D.The equal cost multipath configuration

Which of the following is NOT a required configuration step to successfully run IS-IS on a router?

• A.The router needs to be associated with an IS-IS area ID.
• B.Layer-3 interfaces that will participate in IS-IS need to be identified.
• C.A reference bandwidth needs to be configured to calculate link costs.
• D.The IS-IS context needs to be enabled.

Refer to the exhibit.

In the diagram, all routers are using IS-IS as their routing protocol. The number next to each link is its metric value.
What path will traffic follow from router R6 to router R3, and from router R3 to router R6?

• A.Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3-R4-R2-R5-R6).
• B.Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3-R2-R5-R6).
• C.Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3-R4-R7-R5-R6).
• D.Router R6 to router R3 will follow (R6-R5-R7-R4-R3). Router R3 to router R6 will follow (R3-R4-R7-R5-R6).

Refer to the exhibit.

A static route has been configured on router R1 to reach the PC at 139.120.121.2.
What might be causing the ping to fail?

• A.Router R1 needs a static route to router R2.
• B.The configured next hop does not belong to a subnet adjacent to R1.
• C.The configured static route needs to be a default route.
• D.Router R2 needs a static route to the PC.

Refer to the exhibit.

Routers R1 through R4 in the diagram have established IS-IS adjacencies. Router R1 is L1/L2 and is the DIS of its two broadcast interfaces. How many LSPs will it generate?

• A.2
• B.5
• C.3
• D.4
