Juniper Juniper Certifications JN0-347 Questions & Answers

• Question 31:

  Click the Exhibit button. In the exhibit, each IP subnet in the campus environment is associated with a unique VLAN ID. Which action will ensure that Host C will communicate with Host A and Host B?

  

  A. Configure an IRB interface for each VLAN and associate it with its corresponding VLAN.

  B. Configure all switch ports connecting to the host devices as trunk ports associated with all VLANs.

  C. Configure a port-based ACL that permits inter-VLAN routing for all configured VLANs.

  D. Configure all switch ports connecting to the host devices as access ports associated with a common VLAN.

  Correct Answer: A

  Configuring Routing Between VLANs on One Switch to segment traffic on a LAN into separate broadcast domains, you create separate virtual LANs (VLANs). Of course, you also you want to allow these employees to communicate with people and resources in other VLANs. To forward packets between VLANs you normally you need a router that connects the VLANs. However, you can accomplish this on a Juniper Networks switch without using a router by configuring an integrated routing and bridging (IRB) interface (also known as a routed VLAN interface-- or RVI-- in versions of Junos OS that do not support Enhanced Layer 2 Software).

• Question 32:

  Click the Exhibit button.

  

  You manage the Layer 2 network shown in the exhibit. You experience a failure on the ge-0/0/0 link

  between Switch-1 and Switch-2.

  Which statement is correct about the expected behavior?

  A. Switch-3's ge-0/0/2 port role and state will transition to designated and forwarding.

  B. Switch-3's ge-0/0/2 port role and state will remain as alternate and discarding.

  C. Switch-3 will become the root bridge for the RSTP topology.

  D. Switch-3 will remove the ge-0/0/2 interface from the RSTP topology.

  Correct Answer: A

• Question 33:

  Click the Exhibit button.

  

  Referring to the exhibit, which two statements are true regarding IS-IS adjacencies? (Choose two.)

  A. Level 1 adjacencies can be formed between Router 3 and Router 4.

  B. Level 2 adjacencies can be formed between all routers.

  C. Level 2 adjacencies can only be established between Router 1 and Router 2.

  D. No IS-IS adjacencies can be formed.

  Correct Answer: AB

• Question 34:

  You received an alert from your monitoring system that the master Routing Engine (RE) on an EX4300 switch in a virtual chassis has hardware issues and might need to be replaced. Because the switch already had graceful Routing Engine switchover (GRES) enabled and configured, you must perform a manual switchover to the backup CK to avoid disruption. Which command would be used to perform the manual CK switchover?

  A. Log in to the backup CK and issue the request chassis-control operation command.

  B. Log in to the backup CK and issue the request chassis routing-engine master switch operation command.

  C. Log in to the backup CK and issue the request chassis routing-engine master acquire operation command.

  D. Log in to the backup CK and issue the request iccp-service operation command.

  Correct Answer: B

• Question 35:

  What are three types of bridge protocol data units? (Choose three.)

  A. media endpoint discovery

  B. topology change acknowledgement

  C. topology change notification

  D. type length value

  E. configuration

  Correct Answer: BCE

• Question 36:

  Click the Exhibit button.

  

  You created a policy to reject all incoming routes from peer 2.2.2.2. You notice that despite applying the

  policy, you are still receiving routes from this peer.

  Referring to the exhibit, why are you still receiving the routes?

  A. The policy should have a form statement.

  B. You can only block active prefixes.

  C. The policy should be an import policy.

  D. You cannot block incoming IBGP routes.

  Correct Answer: C

• Question 37:

  Which two statements are true about Virtual Chassis? (Choose two.)

  A. It is possible to automatically update the Junos OS on newly added members to participate in the Virtual Chassis

  B. A software version mismatch on a newly added member must be placed in linecard mode.

  C. Virtual Chassis members use VCCP to create a loop-free topology.

  D. The member ID is not preserved through reboots.

  Correct Answer: AC

• Question 38:

  What is considered a requirement for passing traffic through GRE tunnels?

  A. Tunnel endpoints must have static routes pointing to the remote endpoints.

  B. You must configure the tunnel on the physical interface connecting to the remote endpoint.

  C. You must be able to reach the remote endpoint through the tunnel.

  D. Tunnel endpoints must have a route that directs traffic into the tunnel.

  Correct Answer: C

• Question 39:

  Which two statements are true about link aggregation groups (LAGs)? (Choose two.)

  A. Member links must use contiguous ports on the same member switch.

  B. Duplex and speed settings are not required to match on both participating devices.

  C. If one-member link fails, the LAG can continue to carry traffic over the remaining links.

  D. LAGs increase available bandwidth based on the number of member links.

  Correct Answer: CD

• Question 40:

  Which two statements describe the BGP Local Preference attribute? (Choose two.)

  A. The attribute can be altered through a BGP configuration or using a policy.

  B. The attribute is transmitted across EBGP links.

  C. The attribute can be given a higher preference by configuring a lower numerical value.

  D. The attribute can be used to direct all outbound traffic through a specific peer.

  Correct Answer: AD
