Juniper Juniper Certifications JN0-347 Questions & Answers

• Question 91:

  Which two statements are true about OSPF not-so-stubby areas? (Choose two.)

  A. The ASBR originates Type 7 LSA a for redistributed external routes.

  B. Type 5 LSAs are translated by the ASBR into Type 7 LSAs.

  C. The ASBR originates Type 5 LSAs for redistributed external routes.

  D. Type 7 LSAs are translated by the ABR into Type 5 LSAs.

  Correct Answer: AD

  Redistribution into an NSSA area creates a special type of link-state advertisement (LSA) known as type 7, which can only exist in an NSSA area; An NSSA autonomous system boundary router (ASBR) generates this LSA and an NSSA area border router (ABR) translates it into a type5 LSA, which gets propagated into the OSPF domain.

• Question 92:

  Which two statements describe aggregate routes? (Choose two.)

  A. Invalid routing prefixes are not advertised to external peers.

  B. Internal routing instabilities can be hidden from external peers

  C. Groups of routes are combined into a single route entry.

  D. The route receives the next hop of the primary contributing route.

  Correct Answer: BD

• Question 93:

  Which area is reserved for the OSPF backbone?

  A. Area 0.0.0.0

  B. Area 1.1.1.1

  C. Area 2.2.2.2

  D. Area 3.3.3.3

  Correct Answer: A

• Question 94:

  

  Referring to the exhibit, which statement is correct?

  A. This device is the root bridge.

  B. The spanning tree session has timed out.

  C. The bridge priority on the root device is set to 8k.

  D. The local bridge priority is set to 8k.

  Correct Answer: C

  The Root ID field is the Bridge ID of the elected spanning tree root bridge. The bridge ID consists of a configurable bridge priority and the MAC address of the bridge. Here the bridge priority is 8192, which is 8k.

• Question 95:

  Click the Exhibit button.

  

  Referring to the exhibit, which effect does the configuration on R2 have on OSPF routing in the network?

  A. R2 will block traffic destined to the 192.168.10.0/24 network.

  B. A summary route for the 192.168.10.0/24 network will be advertised to Area 0.

  C. The 192.168.10.0/24 route will not be advertised to Area 1.

  D. Area 2 will use a default route to reach Area 0 and Area 1.

  Correct Answer: C

• Question 96:

  You have deployed a Juniper EX Series switch in the network. The switch receives a broadcast frame on

  an interface.

  Which statement describes the behavior of the switch?

  A. The frame is flooded out all ports that are part of the same VLAN as the receiving port, except for the port on which the frame was received.

  B. The frame is flooded out all ports in all VLANs configured on the switch.

  C. The frame is re-transmitted as a multicast frame on all ports on the switch.

  D. The frame is flooded out all ports that are part of the same VLAN as the receiving port, including the port on which the frame was received.

  Correct Answer: A

• Question 97:

  Which two statements are correct about a Virtual Chassis?

  A. A Virtual Chassis is managed using a single virtual console port.

  B. Each device must be managed separately.

  C. All members in a Virtual Chassis must be running the same Junos version.

  D. You must use the same EX Series switch for all members in a Virtual Chassis.

  Correct Answer: AC

  A: You can connect a PC or laptop directly to a console port of any member switch to set up and configure the Virtual Chassis. When you connect to the console port of any member switch, the console session is redirected to the master switch.

  C: In a Virtual Chassis, each member switch must be running the same version of Juniper Networks Junos operating system (Junos OS).

• Question 98:

  Referring to the configuration shown in the exhibit, which statement is true?

  

  A. RP2 stops sending all SA messages to its peer.

  B. RP1 stops sending all SA messages to its peer.

  C. RP2 stops sending SA messages for the group 224.7.7.7 from source 192.168.100.10 to RP1.

  D. RP1 stops sending SA messages for the group 224.7.7.7 from source 192.168.100.10 to RP2.

  Correct Answer: C

• Question 99:

  Click the Exhibit button. Given the configuration shown in the exhibit, what will be the threshold for storm control?

  

  A. 100 Kbps (kilobits per second)

  B. 100 Mbps (megabits per second)

  C. 100% (percent of link bandwidth)

  D. 100 pps (packets per second)

  Correct Answer: A

  This example shows how to configure the storm control level on interface ge-0/0/0 by setting the level to a traffic rate ,000 Kbps, based on the traffic rate of the combined applicable traffic streams. To configure storm control: Specify the traffic rate in Kbps of the combined traffic streams on a specific interface: [edit ethernet-switching-options] user@switch# set storm-control interface ge-0/0/0 bandwidth 15000

• Question 100:

  What are two terminating actions of a Layer 2 firewall filter? (Choose two.)

  A. reject

  B. accept

  C. log

  D. discard

  Correct Answer: BD
