A static route has been configured on router R1 to reach the PC at 139.120.121.2. However, as shown in the exhibit, the ping fails. What is the most likely cause of the problem?

A.

Router R2 does not have a route to the system address of router R1 and therefore cannot respond to the ping.

B.

There is no default route configured on the PC.

C.

Router R2 does not have a route configured to the PC.

D.

Router R1 needs to be configured with a default route.

Which of the statements below best describes the operation of the IPv6 anycast address?

A.

A packet with a destination anycast address is sent to all nodes on the local link.

B.

A packet with a destination anycast address is sent to all nodes on the local network.

C.

A packet with a destination anycast address is sent to all nodes that have joined the anycast group.

D.

A packet with a destination anycast address is sent to the nearest node that is assigned the anycast address

E.

A packet with a destination anycast address is sent to all nodes that are assigned the anycast address.

Refer to the exhibit below. The routers have an established IS-IS L2 adjacency on which IPv4 system addresses are exchanged. An operator successfully configures multi-topology IS-IS routing so that the IPv6 system addresses are also exchanged between routers. Which of the following statements best describes the number of IS-IS adjacencies and the number of LSPs in the LSDB of R1 AFTER IPv6 has been configured?

A.

R1 has one IS-IS adjacency and one LSP.

B.

R1 has one IS-IS adjacency and two LSPs.

C.

R1 has one IS-IS adjacency and four LSPs.

D.

R1 has two IS-IS-adjacencies and two LSPs

E.

R1 has two IS-IS adjacencies and four LSPs

The 192 168 3.0/24 network is learned on router R1 via IS-IS Given the OSPF configuration shown, and assuming that the OSPF adjacency between routers R1 and R3 is up, why is the 192 168.3.0/24 route not in router R3's route table? (Choose two)

A.

The route policy should be applied as in import policy

B.

The no-redistribute-external command is used on router R1

C.

The route policy is incorrect. It should say "from protocol ISIS" rather than "from protocol direct".

D.

It is not possible to be an ASBR and an NSSA. The ASBR configuration should be removed.

E.

The interface between routers R1 and R3 needs to be in OSPF area 0 rather than OSPF area 1 because a backbone area must always exist.

What is another term to describe the default route for a client?

A.

Black hole

B.

Default gateway

C.

Gateway path

D.

Proxy ARP

Which of the following OSPFv3 LSAs have an AS scope?

Router LSA

C.

Network LSA

D.

Inter-Area Router LSA

E.

Intra-Area Prefix LSA

F.

None of the above LSAs have an AS scope.

A router sets the E bit in the flags of its Type 1 LSA. What does this indicate?

A.

The router is an ABR.

B.

The router is an ASBR.

C.

The router is at the end of a virtual link.

D.

The router's interface is in a stub area.

Which of the following are types of routers in an IS-IS topology? Choose three answers

A.

Level 0

B.

Level 1

C.

Level 2

D.

Level 0/1

E.

Level 1/2

A router receives an OSPF database description packet from a neighbor that references an LSA, which is already in the router's LSDB. The sequence number in the DBD packet is lower than the sequence number of the LSA in the LSDB.

What action does the router take?

A.

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

B.

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

C.

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

D.

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

E.

The router takes no action.

Challenge handshake authentication protocol (CHAP)

B.

Two factor authentication

C.

MD5 authentication

D.

Extensible authentication protocol (EAP)
