JN0-351 Online Practice Questions and Answers

What are three requirements to ensure proper GRE or IP-IP tunnel routing? (Choose three.)

A. Keepalives must be used on stateless tunneling protocols.

B. Tunnel endpoints must have a route that directs traffic into the tunnel.

C. BGP must be used on intermediate devices.

D. Tunnel endpoints must have a valid route to the remote endpoint.

E. All intermediary devices must have a route to the tunnel endpoints.

What are three types of port designation specific to Private VLANs? (Choose three.)

A. Promiscuous ports

B. Transparent ports

C. PVLAN trunk ports

D. Designated ports

E. Isolated ports

You were provided a network diagram that told you to number your network from the 191.255.0.0/16 space. OSPF is enabled and adjacencies are up, but no routers are learning any routes. What can explain this?

A. The default OSPF export policies advertise nothing, so you need to apply export policy

B. The default OSPF import policy rejects all OSPF routes, so you need to apply import policy

C. You need to modify the martian table with a 191.255.0.0/16 accept statement

D. You need to enable OSPF on the lo0 interface to provide a route to the RID of each router in the network

Which protocol supports tunneling of non-IP traffic?

A. GRE

B. SSH

C. IPsec

D. IP-IP

Click the Exhibit button.

Which statement is true about the configuration shown in the exhibit?

A. Only the next-hop-self export policy will be evaluated when routes are sent to neighbor 172.30.1.1.

B. Both the adv-aggregate and adv-custom export policies will be evaluated when routes are sent to neighbor 172.30.2.1.

C. Both the adv-aggregate and next-hop-self export policies will be evaluated when routes are sent to neighbor 172.30.1.1.

D. Only the adv-custom export policy will be evaluated when routes are sent to neighbor 172.30.2.1.

You have two routers unable to form an IS-IS Level 1 adjacency.

Which two statements describe a reason for this problem? (Choose two.)

A. The MTU is set to 1500.

B. Interface lo0 is not included as an IS-IS interface.

C. The area numbers are different.

D. The interfaces are on different subnets.

What are three reasons a router would send out an IS-IS link-state PDU? (Choose three.)

A. A new external route is imported from BGP.

B. The router's link to a neighbor goes down.

C. A new neighbor exists on the link.

D. The cost of a link to an existing neighbor has changed.

E. IS-IS sends link-state PDUs at random intervals.

What is the default keepalive time for BGP?

A. 10 seconds

B. 60 seconds

C. 30 seconds

D. 90 seconds

You are receiving multiple BGP routes from an upstream neighbor and only want to advertise a single summarized prefix to your internal OSPF neighbors. This route should only be advertised when you are receiving these BGP routes from this neighbor.

In this scenario, which type of route should you create?

A. aggregate route

B. static route using the resolve feature

C. generate route

D. static route using qualified next hops

Exhibit.

You are using OSPF to advertise the subnets that are used by the Denver and Dallas offices. The routers that are directly connected to the Dallas and Denver subnets are not advertising the connected subnets.

Referring to the exhibit, which two statements are correct? (Choose two.)

A. Create static routes on the switches using the local vMX router's loopback interface for the next hop.

B. Configure and apply a routing policy that redistributes the Dallas and Denver subnets using Type 5 LSAs.

C. Configure and apply a routing policy that redistributes the connected Dallas and Denver subnets.

D. Enable the passive option on the OSPF interfaces that are connected to the Dallas and Denver subnets.
