Juniper Juniper Certifications JN0-343 Questions & Answers

• Question 191:

  

  An IP tunnel connects two routers over the Internet as shown in the exhibit.

  Which two statements are correct? (Choose two.)

  A. A tunnel interface can serve as a next hop for static routes or participate in the network's IGP.

  B. Routing protocols will always prefer a tunnel over a physical link because the tunnel is a one-hop link with the lowest cost path.

  C. You can ensure the IP tunnel serves as the backup path through administrative settings such as cost and route preference.

  D. IP tunnels are subject to the same simple firewall rules as the direct link between the two routers, because the original IP header contents are open for the transit devices to see.

  Correct Answer: AC

• Question 192:

  

  Your current network is using Switch-1 and Switch-2 as a Layer 3 core pair. You change the EX series switch core into a VC and configure the links between the switches to be a LAG.

  Assuming that Switch-3 is operating at Layer 2 only, which two protocols would be removed from this portion of the network? (Choose two.)

  A. GRES

  B. BFD

  C. VRRP

  D. STP

  Correct Answer: CD

• Question 193:

  Which two new port roles does RSTP introduce? (Choose two.)

  A. backup

  B. forwarding

  C. alternate

  D. designated

  Correct Answer: AC

• Question 194:

  Which statement describes how root protection protects your network?

  A. It dynamically modifies the STP bridge priority to the best value in your network.

  B. It ignores superior BPDUs from being accepted on a protected interface.

  C. It changes protected ports to the blocking state if they receive superior BPDUs.

  D. It is enabled on a switch and uses BPDUs to negotiate a better bridge priority than its neighbors.

  Correct Answer: C

• Question 195:

  -- Exhibit ?

  

  -- Exhibit -Which statement describes what is happening in the exhibit?

  A. A redistribution policy is defined under the [edit policy-options] hierarchy and applied to router R3 under the [edit protocols ospf] hierarchy.

  B. A firewall policy is defined under the [edit policy-options] hierarchy and applied to router R3 under the [edit protocols ospf] hierarchy.

  C. A redistribution policy is inherited by router R3.

  D. A redistribution policy is not properly configured.

  Correct Answer: A

• Question 196:

  Which protocol provides redundancy in a LAN environment through the use of master and backup routers?

  A. BGP

  B. BFD

  C. VRRP

  D. RIP

  Correct Answer: C

• Question 197:

  Several routers share a common LAN segment in area 224 and have formed adjacencies using IS-IS. One router is elected as the designated intermediate system (DIS).

  To which multicast address will the peers send their hello packets?

  A. 224.0.0.5

  B. 224.0.0.6

  C. 01:80:C2:00:00:14

  D. 49.0001.0224.0000.0015.00

  Correct Answer: C

• Question 198:

  In which two situations will the BGP next-hop attribute point to Router A? (Choose two.)

  A. When Router A sends routing updates to its EBGP peer Router B with multihop configured.

  B. When Router A sends routing updates to its IBGP peer Router B when route reflectors are not used.

  C. When Router A sends routing updates to its IBGP peer Router B when route reflectors are used.

  D. When Router A sends routing updates to its IBGP peer after redistributing routes to BGP from an IGP.

  Correct Answer: AD

• Question 199:

  -- Exhibit -routing-options {

  router-id 10.10.1.2;

  }

  policy-options {

  policy-statement loadbalance {

  term 1 {

  from {

  route-filter 100.100.0.0/16 exact;

  }

  then {

  load-balance per-packet;

  }

  }

  }

  }

  -- Exhibit -Referring to the exhibit, you have configured a load balancing policy and the router has an equal cost path for traffic to 10.100.0.0/16.

  What must you do to complete the load balancing configuration?

  A. Apply the policy as an export policy under the [edit forwarding-options] hierarchy.

  B. Apply the policy as an import policy under the [edit forwarding-options] hierarchy.

  C. Apply the policy as an export policy under the [edit routing-options forwarding-table] hierarchy.

  D. Apply the policy as an import policy under the [edit routing-options forwarding-table] hierarchy.

  Correct Answer: C

• Question 200:

  Routers R1, R2, R3, and R4 are all connected on the same OSPF network segment. While viewing the output of the show ospf neighbor command on R1, you notice that the interface towards R2 is always in the 2Way state.

  What would cause this state?

  A. R1 is a DR device and R2 is a DROther device.

  B. R1 and R2 are both DROther devices.

  C. R1 and R2 are both BDR devices.

  D. R1 is a DROther device and R2 is a DR device.

  Correct Answer: B
