Juniper Juniper Certifications JN0-343 Questions & Answers

• Question 341:

  

  In the exhibit, R5 is exporting the RIP network prefixes into OSPF. You want to limit the number of LSAs sent to Area 2.2.2.2, but you want to ensure that all routers in other are as will have routes to all networks contained in the LSAs sent by the routers in Area 2.2.2.2. Which configuration change will enable this scenario?

  A. Configure Area 2.2.2.2 as a stub area.

  B. Configure Area 2.2.2.2 as a not-so-stubby area.

  C. Configure an area range on R3.

  D. Configure an export filter for OSPF on R3.

  Correct Answer: B

• Question 342:

  

  Router 2 is peered using EBGP to Router 3's physical interface. A route is announced from Router 3 to Router 2. Router 2 then announces this route to Router 1 using IBGP. No routing policies are configured on any of the three routers. What will the BGP next-hop attribute of this route be when examined on Router 1?

  A. 172.17.5.5

  B. 10.10.10.1

  C. 10.10.10.2

  D. 192.168.5.50

  Correct Answer: B

• Question 343:

  

  You want traffic destined for the 66.142.1.0/24 network to traverse an IP-IP tunnel. You notice traffic being sent to any address in that subnet is not being received. Upon reviewing the output shown in the exhibit, what is the problem?

  A. The route is in the wrong routing table.

  B. The route is a static route; a dynamic routing protocol must be used.

  C. The route is not active in the inet.2 routing table.

  D. The route does not point to the IP-IP tunnel.

  Correct Answer: D

• Question 344:

  

  Devices S1 and S2 have the interface configurations as shown in the exhibit. You attach ge-0/0/0 on S1 to ge-0/0/0 on S2. You attach ge-0/0/1 on S1 to ge-1/0/20 on S2. However, the ae0 interface remains down on both S1 and S2. What should you change to cause the ae0 interface to come up?

  A. You should use consecutive interfaces on S2.

  B. You should use interfaces on S2 that are on the same member of the Virtual Chassis.

  C. You should configure at least one switch to run LACP in active mode.

  D. You should make the list of VLANs on the ae0 interfaces on S1 and S2 match.

  Correct Answer: C

• Question 345:

  

  In the configuration shown in the exhibit, you want to form an EBGP peering relationship to the loopback address of a router administered by your ISP, but the session will not establish. What is causing the problem?

  A. EBGP cannot peer to a virtual address.

  B. The EBGP session needs to be explicitly configured with multihop.

  C. The EBGP session needs to be explicitly configured as type external.

  D. The autonomous system information needs to be configured under [protocols bgp].

  Correct Answer: B

• Question 346:

  Which field of the IP header is modified on a payload packet when using GRE?

  A. time to live

  B. source address

  C. protocol

  D. fragment offset

  Correct Answer: A

• Question 347:

  

  In the exhibit, the 172.32.1.0/24 prefix is being sent from Router A to Router B through BGP. When the BGP announcement for 172.23.1.0/24 is sent from Router B and received by Router C, which two attributes will be changed by default? (Choose two.)

  A. AS path

  B. origin

  C. multiple exit discriminator (MED)

  D. next hop

  Correct Answer: AD

• Question 348:

  Two routers have established a peering using EBGP over a single T1 link.

  How often will the routing table be synchronized between the two routers?

  A. every 30 minutes

  B. when an update message is received

  C. every 30 seconds

  D. when a notification message is received

  Correct Answer: B

• Question 349:

  Which configuration will cause IPv4 interface routes from inet.0 to appear in the myinstance routing instance?

  A. routing-options { interface-routes { rib-group inet myribgroup; } rib-groups { myribgroup { import-rib [ inet.0 myinstance.inet.0 ]; } } }

  B. routing-options { interface-routes { rib-group inet myribgroup; } rib-groups { myribgroup { export-rib inet.0; import-rib myinstance.inet.0; } } }

  C. routing-options { interface-routes { import into myinstance.inet.0; } }

  D. routing-options { rib-groups {

  interface-routes {

  import-rib [ inet.0 myinstance.inet.0 ];

  }

  }

  }

  Correct Answer: A

• Question 350:

  You are using redundant trunk groups (RTG) on your network.

  Which two statements accurately describe RTG? (Choose two.)

  A. RTG interfaces pass BPDU packets.

  B. Aggregate Ethernet (AE) interfaces cannot be part of an RTG.

  C. RTG is used as an alternative to STP/RSTP.

  D. RTG connects an access switch to two aggregation switches.

  Correct Answer: CD
