A. A floating static route.

B. A route from OSPF.

C. A route from IS-IS.

D. A static route.

A. The router sends a link-state request to its neighbor.

B. The router updates the information in its LSDB with the information received from its neighbor.

C. The router takes no action.

D. The router sends a link-state acknowledgement to its neighbor.

E. The router sends a link-state update to its neighbor.

A. The route policy should be applied as an import policy.

B. The ASBR configuration should be removed.

C. The interface between routers R1 and R3 must be in OSPF area 0.

D. The route policy should say "from protocol isis" instead of "from protocol direct".

A. ff00::1:2

B. 2001:db8::30a:216:4dff:fe13:5cae

C. fd01:2234:5678::1

D. fe80::216:4dff:fe13:5cae

E. ::ffff:0:0.240.0.0.1

A. A Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area.

B. A Type 4 LSA is originated by an ASBR to describe a route to itself to routers outside the area.

C. A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the backbone area to provide routing information.

D. A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the stub area to provide routing information.

A. OSPF has its own protocol number of 89.

B. OSPF does not use IP.

C. OSPF uses UDP, so the protocol number is 17.

D. OSPF uses TCP, so the protocol number is 6.

A. The system ID

B. The device that first initiated communication becomes the DIS

C. The loopback address

D. The sequence number of the hello packet

A. Backbone Area

B. Standard Area

C. Not So Stubby Area

D. Stub Area

A. The CE routers run only IPv6.

B. IPv6 routes on the PE routers may have an IPv4 address as the next hop.

C. The PE routers must run IPv4 and IPv6.

D. The P routers must run IPv4 and IPv6.

A. Both routes will be installed, regardless of whether ECMP is enabled.

B. The route learned via the OSPF type 5 LSA will be installed.

C. The route learned via IS-IS will be installed.

D. Both routes will be installed, if ECMP is enabled.

A. Convergence will not be triggered because switches cannot run routing protocols between them.

B. Convergence is triggered when the physical interfaces between routers R1 and R2 go down.

C. Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of hello timeouts.

D. Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down.

E. Convergence is triggered when the switches notify the routers about the link-state info.

A. Metric is based on hop count.

B. Link state updates sent using layer 3 multicast.

C. Support for CIDR.

D. Support hierarchy through the use of areas.

E. Slow convergence after link failures.

A. Variable total length, where at least 48 bits are used for the global prefix, 48 bits are used for the subnet and 64 bits are used as an interface identifier.

B. Fixed total of 128 bits, where 32 bits are used for the global prefix, 32 bits are used for the subnet and 64 bits are used as an interface identifier.

C. Fixed total of 128 bits, where 64 bits are used for routing and 64 bits are used as an interface identifier.

D. Variable total length, where at least 64 bits are used for routing and 64 bits are used as an interface identifier

A. Specifying an area address

B. Configuring level capabilities

C. Configuring IS-IS interfaces

D. Enabling IS-IS
