Q52. Exhibit:

You are receiving the same 200.0.0.0/24 BGP route from four different ISPs.
Referring to the exhibit, which ISP’s route would be selected as active?

ISP-A

ISP-B

ISP-C

ISP-D

Q53. You are deploying a new EVPN service for your customers. You must build the service based on the following requirements
— both Layer 2 and Layer 3 functionality must be supported
— your customers must be able to support multiple VLANs in the same EVPN instance (EVI).
In this scenario which two types of routing instances should be configured? (Choose two.)

VRF

virtual switch

virtual router

EVPN

Q54. You are responsible for configuring CoS for your network Your network includes a video application with strict latency requirements, so that any packets delayed by more than 75 ms are effectively useless. You want to ensure that you do not waste buffer space.
When configuring the scheduler for this application, which feature would you use?

exact

remainder

rate limit

temporal

Q55. Exhibit:

A Layer 3 VPN exists in the provider network and the CE devices are connecting to the PE devices using BGP. The PE devices are receiving BGP routes from the CE devices and the PE devices have the CE BGP routes in their respective routing tables. However, the remote CE devices are not receiving the BGP routes.
Referring to the exhibit, what is the problem?

The CE devices are detecting an AS loop

A VRF target community mismatch exists.

A route distinguisher mismatch exists.

The PE devices are detecting an AS loop.

Q56.

Referring to the exhibit, a Layer 3 VPN is configured, however, the routes are being hidden.
What is the problem?

The BGP peer is not reachable through the IGP.

An active MPLS tunnel does not exist between the peers.

A route distinguisher mismatch exists between the peers.

A VRF target community mismatch exists between the peers.

Q57. 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.

Q58. Which two statements about wide and narrow metrics used in IS-IS are correct? (Choose two)

Wide metrics are enabled with the wide-metrics-only parameter under protocols isis hierarchy.

Narrow metrics are enabled by default and use 8 bits in TLVs to send information.

Wide metrics are sent by default and use 24 bits in TLVs to send information.

Disabling narrow metrics results in external routes being leaked from L1 to L2 areas automatically.

Q59.

You are provisioning Layer 2 circuits between sites CE1, CE2, and CE3.
Referring to the exhibit, which statement is true?

A point-to-multipoint LSP must be created between sites.

Each site must have only one VLAN configured to the PE.

Site PE1 must have a point-to-multipoint link configured towards the core.

Two VLANs must be configured from PE 1 to CE 1.

Q60. Exhibit:

You are troubleshooting BGP routing issues between two MX Series routers. The BGP session is established but no BGP routes are being communicated.
What are two reasons for this problem? (Choose two.)

The peer type should be external.

No active BGP routes are in the inet.0 table

table ii No export routing policy is applied.

The peers are in different ASs.

Q61. Exhibit:

CE-1, CE-2, and CE-3 are part of a single VPLS VPN An Ethernet frame has just arrived at PE-3 from CE-3.
It has a source MAC address of CE-3 and a destination MAC address of CE-1. You want to know what PE-3 does with the Ethernet frame.
Referring to the exhibit, which statement is correct?

It forwards the packet to PE-1 only.

It drops the packet because the destination MAC address is not for PE-3.

It forwards the packet to PE-1 and PE-2.

It drops the packet because the destination MAC address is not in PE-3’s MAC table.

Q62. Exhibit:

Referring to the exhibit, external routes are being received at R1. These routes must appear on R5.
Which action will produce this result?

Turn on wide metrics on R1 and R2 and write an export policy on R4 from level 2 to level 1 matching the external routes.

Turn on wide metrics on R4 and R5 and write an export policy on R2 from level 1 to level 2 matching the external routes.

Write an export policy on R4 from level 2 to level 1 matching the external routes.

Write an export policy on R2 from level 1 to level 2 matching the external routes.

Q63. Exhibit:

A network administrator is concerned about the number of LSAs that they are observing on the network.
What will reduce Type 7 LSAs advertised from R2 to the non-backbone routers shown in the exhibit?

Configure no-summaries under protocols ospf3 on R2.

Configure no-naaa-abr under protocols ospf3 on R2.

Configure no-summaries under area 0.0.0.2 on R2.

Configure nssa under area 0.0.0.2 on R2.

Q64. Exhibit:

R2 is receiving the same route from R1 and R3. You must ensure that you can load balance traffic for that route.
Referring to the exhibit, which two configuration changes will allow load balancing? (Choose two.)

Configure muitipath under group R1.

Configure muitipath under the global BGP configuration.

Apply the prepend policy as an import policy under group R3.

Apply the prepend policy as an import policy under group R1.

Q65. Exhibit:

Referring to the exhibit, a Layer 3 VPN is configured, however, the routes are being hidden.
What is the problem?

A route distinguisher mismatch exists between the peers.

A VRF target community mismatch exists between the peers.

The BGP peer is not reachable through the IGP.

An active MPLS tunnel does not exist between the peers.

Q66. Exhibit.

You have the LDP signaled VPLS topology as shown in the exhibit CE-B at Site-2 is multihomed to both PE-2 and PE-3 In this scenario where would you configure loop prevention?

PE-2

PE-3

CE-B

Q67. Exhibit.

You have a Layer 3 VPN established between PE-1 and PE-2 to allow communication between CE-1 and CE-2 You want to establish communication between CE-1 and CE-2.
