Verified 300-510 exam dumps Q&As with Correct 101 Questions and Answers

NO.13 Refer to me exhibit.

A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501. The engineer wants to block all the routers coming from ASN 64502. but allow all the others. For that purpose, the following AS Pam prefix 1st s being used:

What must be fixed to achieve this result?

The AS-PATH filter must be defined inside the route-map mode

At the end ip as-path access-list 10 permit .* must be included

The statement must be modified with ip as-path access-list 1 deny _64502_

The statement must CM modified with ip as path access list 1 deny A64502$

NO.14 What is enabled by default on Cisco IOS-XR routers and cannot be disabled?

SSH server

Multicast routing

IPv4 and IPv6 CEF

IPv6 routing

CDP

BFD

NO.15 Refer to the exhibit.

A network operator wants to expand the segment routing global block in upcoming maintenance. The operator must ensure that the changes to the segment routing global block have no adverse impacts on the prefix-sid associated with the loopback0 interface used within the OSPF domain.
Which command can the operator use to enforce R2 to have a strict prefix-sid assignment to loopback0?

Option A

Option B

Option C

Option D

NO.16 Refer to the exhibit.

P1 and PE3 Cisco IOS XR routers are directly connected and have this configuration applied. The BGP session is not coming up. Assume that there is no IP reachability problem and both routers can open tcp port 179 to each other. Which action fixes the issue?

Change HMAC-MD5 to HMAC-SHA1-20

Configure the send and accept lifetime under key 1

Change HMAC-MD5 to MD5

Change HMAC-MD5 to HMAC-SHA1-12

NO.17 A network consultant is troubleshooting IS-IS instances to identify why a routing domains is having communication problems between the two instances.
Which description of the possible cause of issues in the routing domain is true?

The same interface cannot be advertised in two different IS-IS instances

The IS-IS “ISP” and “ISP2” instances are unrelated and unable to intercommunicate

The configured IS-IS NSEL value is not allowing the routing systems to establish a neighborship

The interface mode ip router is-is command was not included in the script

NO.18 Refer to the exhibit.

An engineer working for a private telecommunication company with an employee id 3977 74 814 implemented the configuration on Router 1. what is the effect of it?

Router 1 sends and receives multiple best paths from neighbor 192.168.1.1

Router 1 sends up to three paths to neighbor 192.168.1.1 for all routes

Router 1 sends only one best path to neighbor 192 168.1.1.

Router 1 receives only one best path from neighbor 192.168.1.1

NO.19 Refer io the exhibit. While applying the configurations on two routers an engineer notices that OSPF adjacency Between them remains down. Through the ping test the engineer confirmed that both me routers have Layer 3 reachability between them. Which action should me engineer take to make the adjacencies to full?

Enter the command ip ospf authentication in R2 interface

Enable OSPF just inside the router OSPF process not in the interfaces of any router

Delete the area 0 authentication message-digest command from the OSPF process in R1

Delete the area 0 authentication message-digest command from the OSPF process in R2

NO.20 Refer to the exhibit.

P1 and PE3 Cisco IOS XR routers are directly connected and have this configuration applied. The BGP session is not coming up. Assume that there is no IP reachability problem and both routers can open tcp port 179 to each other. Which two actions fix the issue? (Choose two.)

Change MD5 to HMAC-SHA1-12

Change MD5 to HMAC-ESP

Change MD5 to SHA-1

Change MD5 to HMAC-MD5

Remove the send and accept lifetime under key 1

NO.21 Which two statements about route reflectors are true? (Choose two.)

Routes received from nonclient peers are reflected to route reflector clients as well as nonclient peers.

Routes received from nonclient peers are reflected to route reflector cluster as well as OSPF peers.

If a router received an iBGP route with the originator-ID attribute set to its own router ID, the route is discarded.

Routes received from a route reflector client is reflected to other clients and nonclient peers.

If a route reflector receives a route with a cluster-list attribute containing a different cluster ID, the route is discarded.

NO.22 Which cost is the default when redistributing routes from BGP to OSPF?

infinite

automatic

NO.23 Drag and Drop Question
Compare different features between OSPFv2 and OSPFv3.
Drag and drop the descriptions of OSPF from the left onto the correct OSPF versions on the right.

NO.24 Refer to me exhibit. A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501.

The engineer wants to block all the routers coming from ASN 64502. but allow all the others. For that purpose, the following AS Pam prefix 1st s being used:
(config)#ip as-path access-list 10 deny _64502$
What must be fixed to achieve this result?

The AS-PATH filter must be defined inside the route-map mode

At the end ip as-path access-list 10 permit .* must be included

The statement must be modified with ip as-path access-list 1 deny _64502_

The statement must CM modified with ip as path access list 1 deny A64502$

NO.25 Refer to the exhibit. Routers R1, R2. R3, and R4 have been configured to run OSPF. and router R5 is running EIGRP Traffic from R1 to R5 is expected to pass via R4. but OSPF routing has calculated the best path via R3.
Which action corrects the problem?

Configure R3 to use metric-type 1 with a higher metric than R4.
