Question # 42

Refer to the exhibit. An engineer working for a private telecommunication company with an employee id: 4233:46:364 notices that the customer network going through AS30-AS65001-AS65000 is experiencing packet drops when it accesses an application at 172.16.20.1/32 In the DC cloud. The BGP link between AS20 and AS30 is inaccessible because of a fiber cut. Routers RL, RN, and RZ are configured with confederation identifier 10. Which action resolves this Issue?

Questions # 43:

network engineer must implement a segment routing policy rule that specifies that SIDs are bounded manually. The policy will be used for traffic steering based on incoming label ..with the binding SIDs, adjacency SIDs, and BGP peering SIDs. All labels will be in the local segment with the range from 40000 to 50000. How must the engineer implement … label allocation?

Options:

A.

Implement the standard default SRGB range in the SR global segment.


B.

Implement a non-default SRGB range in the SR local segment.


C.

Implement a non-default SRLB range in the SR global segment.


D.

Implement the default SRLB range in the SR local segment

Question # 44

Refer to the exhibit. Router R1 is expected to receive routes that originate from AS 65547 only. However, R1 is receiving routes from AS 65547 and several other ASs that are directly attached to it. Which change to the AS path permit filter corrects the problem?

Options:

A.

Change the regular expression to $.


B.

Change the regular expression to.*.


C.

Change the regular expression to _65547_.


D.

Change the regular expression to A65547$

Questions # 45:

Refer to the exhibit Dedicated MPLS Layer 3 services for VRF customer A are configured on the MPLS network for FTP access OSPF with area 0 configuration is used as the interior routing protocol between the routers, and LDP is up and running on the MPLS network. After recent maintenance work on the MPLS network. IP address 172.16 100 1 cannot access the FTP server with IP address 172.16 192.21 All loopbacks are reachable on the network Which configuration must the engineer apply to correct the problem?

Options:

A.

Configure passive-interface under the Gi0/2 interface on R22


B.

Configure ip ospf network point-to-point under the Lo0 interface on R33


C.

Configure network 33.33.10.1 0.0.0.255 area 0 under the OSPF configuration on R33


D.

Configure ip cef under the global configuration on R22

B.

Define area 2 as a NSSA on R2 and R3


C.

Configure virtual links between RI and R3.


D.

Configure interface F0/0 on RI and R2 to be in area O.

Refer to the exhibit.

Question # 48

A service provider is running IS-IS in the core, and all routers use the default IS-IS configuration and reside in the same area. All routers maintain a different 6 bytes for the system ID. but the attached bits in the NET are the same. After an engineer added router R6 to the network. R3 and R5 began to experience CPU processing issues. Which action must the engineer take to resolve the issue?

Options:

A.

Configure all routers lo operate as IS-IS Level 1 routers by altering the attached bit to ensure that a default route is Injected Into the routing tables.


B.

Configure R6 to operate as a Level 1 router only so that it maintains the Level 1 database for all routers.


C.

Configure routers R5 and R3 to operate as Level 1 routers only so that they inject a default routing into the routing tables of the other routers


D.

Configure all routers to operate as IS-IS Level 2 routers so that only a Level 2 database is maintained.
