Question # 4

The link between CE1 and PE1 has a history of flapping To avoid the impact that flapping causes to the network you decide to use route damping

Which statement is correct in this scenario?

Dampened routes decay at a sliding rate known as half-life

Routes become dampened when the configured max-suppress value is reached

Dampening is enabled on interfaces

Dampened routes become active when their figure of merit drops below the reuse value.

Referring to the show isis database command output shown in the exhibit, what is causing this problem on the network?

R1 and R2 are in different IS-IS areas.

The preferred interface between R1 and R2 is experiencing errors

R1 is configured to drop all incoming traffic.

R2 is ignoring specific LSPs from R1 in its SPF calculations.

Question # 8

You are establishing a Layer 3 VPN between two PE devices Currently you have a single internal IPv4 BGP peering between the PE devices. You must ensure that the IPv4 and IPv6 routes from both CE devices are exchanged between these sites

Which two statements are correct in this scenario? (Choose two.)

You must establish an IPv6 BGP peering between the two PEs

You must enable the inet-vpn NLR on both PE devices.

You must enable the inet6-vpn NLRI on both PE devices.

You must enable IPv6 tunneling on the LSPs between the PE devices

Question # 9

Exhibit.

Referring to the exhibit, which statement is true?

The BGP session between R1 and R2 will fail to establish correctly due to an NLRI mismatch

The BGP session between R1 and R2 will establish correctly and the met unicast and the met6 unicast NLRIs will pass routing information

The BGP session between R1 and R2 will establish correctly and only the inet6 unicast NLRI will pass routing information

The BGP session between R1 and R2 will establish correctly and only the met unicast NLRI will pass routing information

Question # 10

Exhibit:

Traffic is being sent from R2 to R3. The link between R2 and R3 fails.

Referring to the exhibit, which statement is correct?

Traffic will automatically reroute using the shortest path, which is R2 to R1 to R3.

Traffic will automatically reroute using R2 to R4 to R1 to R3.

Manual intervention is required for traffic to be rerouted.

Traffic will automatically reroute distributed between all available paths.

Question # 11

Exhibit:

You are troubleshooting an issue where R1 is no longer receiving the default IS-IS route from R3.

Referring to the exhibit, which action would you take to solve the problem?

Delete the protocols isis ignore-attached-bit configuration statement on R3.

Delete the protocols isis import configuration statement on R1.

Delete the protocols isis level 2 disable configuration statement on R3.

Delete the protocols isis ignore-attached-bit configuration statement on R1.

Question # 12

Exhibit.

Two CE devices (CE-1 and CE-2) belong to the same customer and connect into a single PE device (PE-1) However, the CE devices cannot communicate with each other You want to allow the CE devices to communicate with each other

Referring to the exhibit, which action would solve the problem?

Configure both routing instances with the set routing-opt ions auto-export-statement

Configure both routing instances with the set routing-options autonomous-system loops 3 statement

Configure both routing instances with the vrf-table-label statement

Configure both routing instances with the as-override statement within the BGP protocol

Question # 13

Which statement is correct about BGP FlowSpec between a service provider's PE router and a customer?

The NLRI received from a customer is stored in the flowspec. inet .0 table.

The RFC deterministic traffic filtering algorithm is used by default in Junos.

The flow routes received from a customer are limited to /32 masks for IPv4.

The NLRI received from a customer is stored in the inetfiow.0 table

Question # 14

Exhibit:

The exhibit shows a BGP peering session for two PE routers. The BGP session is up, but the hosts in the Layer 2 VPN that uses the BGP session are unable to communicate.

What is the problem in this situation?

The BGP peer does not support the restarter functionality.

The local BGP router does not support Layer 2 VPN and Layer 3 VPN NLRI address families at the same time.

There is a mismatch in the supported NLRI address families between the BGP peers.

The BGP peer does not support the add-path feature.
