B. The ge-0/0/0 and ge-0/0/1 interfaces are operating in trunk mode.

C. All three interfaces are operating in access mode.

D. The ge-0/0/2 interface is operating as a Layer 3 interface.

What are two reasons for creating multiple areas in OSPF? (Choose two.)

A. to reduce the convergence time

B. to increase the number of adjacencies in the backbone

C. to increase the size of the LSDB

D. to reduce LSA flooding across the network

Exhibit

Your BGP neighbors, one in the USA and one in France, are not establishing a connection with each other. Referring to the exhibit, which statement is correct?

A. The BFD liveness is set too low.

B. The BFD liveness must be configured on the BGP neighbor.

C. The BFD liveness must be configured on the BGP group.

D. The BFD liveness is set too high.

Exhibit

You are troubleshooting an issue where traffic to 192.168.10.0/24 is being sent to R1 instead of your desired path through R2. Referring to the exhibit, what is the reason for the problem?

A. R2's route is not the best path due to loop prevention.

B. R2's route is not the best path due to a lower origin code.

C. R1's route is the best path due to a higher local preference

D. R1's route is the best path due to the shorter AS path.

You are a network operator who wants to add a second ISP connection and remove the default route to the existing ISP You decide to deploy the BGP protocol in the network. What two statements are correct in this scenario? (Choose two.)

A. IBGP updates the next-hop attribute to ensure reachability within an AS.

B. IBGP peers advertise routes received from EBGP peers to other IBGP peers.

C. IBGP peers advertise routes received from IBGP peers to other IBGP peers.

D. EBGP peers advertise routes received from IBGP peers to other EBGP peers.

You are configuring a router as a new Level 1 router in an existing Level 1 area. The NET address for an existing Level 1 router is 49.0011.1111.2222.3333.00. The new router must form a Level 1 adjacency with the existing router. What should be the area ID in this scenario?

A. 00

B. 49

C. 0011

D. 3333

You are asked to create a default route that will be advertised to your internal OSPF neighbors. You have three upstream connections to the Internet and you must ensure that when available, all traffic uses ISP1 as your primary connection and only uses ISP2 and ISP3 when ISP1 is not available. Which solution should you implement in this scenario?

A. Create a default static route with ISP1's address as the next hop while specifying the addresses for ISP2 and ISP3 as qualified next hops with a preference value of six or higher.

B. Create a default generate route that includes an import policy to match BGP routes from ISP1 and assign a preference value of four or less.

C. Create a default static route with each neighbor address as the next hop.

D. Create a default aggregated route.

Which two statements about redundant trunk groups on EX Series switches are correct? (Choose two.)

A. Redundant trunk groups load-balance traffic across two designated uplink interfaces.

B. If the active link fails, then the secondary link automatically takes over.

C. Layer 2 control traffic is permitted on the secondary link

D. Redundant trunk groups must be connected to the same aggregation switch.

Which two statements are correct about tunnels? (Choose two.)

A. BFD cannot be used to monitor tunnels.

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

C. IP-IP tunnels are stateful.

D. Tunnels add additional overhead to packet size.

You want to use filter-based forwarding (FBF) on your Internet peering router to loadbalance traffic to two directly connected ISPs based on the source address. Which two statements are correct in this scenario? (Choose two.)

A. FBF uses the no-forwarding routing instance type.

B. FBF uses the forwarding routing instance type.

C. RIB groups are used to copy routes from the inet. o routing table.

D. RIB groups are used to hide routes in the inet. 0 routing table.

You want to redistribute the static routes into BGP, but they do not show as BGP routes. What causes this result to occur?

A. The static routes do not have a valid next hop.

B. The as-path parameter must be specified.

C. A community string must be configured.

D. The no-readvertise feature is specified.
