Juniper Juniper Certifications JN0-347 Questions & Answers

• Question 11:

  What are two OSPF packet types that use multicast for communication on a multicast segment? (Choose two.)

  A. hello

  B. link-state request

  C. database description

  D. link-state update

  Correct Answer: AD

• Question 12:

  What is the default route preference for BGP?

  A. 167

  B. 170

  C. 150

  D. 179

  Correct Answer: B

  BGP has the default preference .

• Question 13:

  Which device is used to separate collision domains?

  A. switch

  B. router

  C. hub

  D. firewall

  Correct Answer: A

  Modern wired networks use a network switch to reduce or eliminate collisions. By connecting each device directly to a port on the switch, either each port on a switch becomes its own collision domain (in the case of half duplex links) or the possibility of collisions is eliminated entirely in the case of full duplex links.

• Question 14:

  There is a GRE tunnel configured over the Internet between Router-1 and Router-2. An OSPF adjacency is

  configured over this GRE tunnel. However, the OSPF adjacency briefly reaches the Full state before it is

  torn down. This cycle repeats indefinitely.

  Which two actions would you perform to solve this problem? (Choose two.)

  A. Configure OSPF to not export the tunnel endpoint interface routes.

  B. Configure the GRE interfaces on both routers as passive interfaces in OSPF.

  C. Configure the physical WAN interfaces on both routers as passive OSPF interfaces.

  D. Configure static routes to the tunnel endpoints.

  Correct Answer: AD

• Question 15:

  Click the Exhibit button. Referring to the exhibit, you are asked to ensure that host-1 can communicate with

  host-3 while also allowing host-2 to communicate with host-4.

  What should you do to enable this behavior?

  

  A. Configure the native-vlan-id default statement under the ge-0/0/1 port settings on Switch-1.

  B. Use the all keyword when defining the member VLANs for the ge-0/0/1 interface on Switch-1.

  C. Configure the native-vlan-id default statement under the ge-0/0/1 port settings on both Switch-1 and Switch-2

  D. Use the all keyword when defining the member VLANs for the ge-0/0/1 interface on both Switch-1 and Switch-2.

  Correct Answer: C

  Configuring Mixed Tagging Support for Untagged Packets For 1-, 4-, and 8-port Gigabit Ethernet IQ2 and IQ2-E PICs, for 1-port 10-Gigabit Ethernet IQ2 and IQ2-E PICs, for all MX Series router Gigabit Ethernet, Tri-Rate Ethernet copper, and 10-Gigabit Ethernet interfaces configured for 802.1Q flexible VLAN tagging, and for aggregated Ethernet interfaces on IQ2 and IQ2-E PICs or MX Series DPCs, you can configure mixed tagging support for untagged packets on a port. Untagged packets are accepted on the same mixed VLAN-tagged port. To accept untagged packets, include the native- vlan-id statement and the flexible-vlantagging statement at the [edit interfaces interface-name] hierarchy level: [edit interfaces ge-fpc/pic/port] flexible-vlan-tagging; native-vlan-id number;

• Question 16:

  You are configuring a new BGP service to your service provider. You want to ensure that BGP is fully established and has all the routes in the route table before allowing traffic to transit the router. Which feature achieves this requirement?

  A. BGP route reflector

  B. IS-IS mesh group

  C. BGP local preference

  D. IS-IS overload bit

  Correct Answer: D

• Question 17:

  You want to provide reachability to your data center by advertising its subnet throughout your upstream

  peer AS.

  However, you do not want this prefix advertised any further.

  Which BGP community value would be used to meet this requirement?

  A. no-advertise

  B. no-export

  C. no-export-subconfed

  D. 65512 - 65535

  Correct Answer: B

• Question 18:

  You were provided a network diagram that told you to number your network from the 191.255.0.0/16 space. OSPF is enabled and adjacencies are up, but no routers are learning any routes. What can explain this?

  A. The default OSPF export policies advertise nothing, so you need to apply export policy

  B. The default OSPF import policy rejects all OSPF routes, so you need to apply import policy

  C. You need to modify the martian table with a 191.255.0.0/16 accept statement

  D. You need to enable OSPF on the lo0 interface to provide a route to the RID of each router in the network

  Correct Answer: C

• Question 19:

  Which Junos feature allows you to combine multiple interfaces into a single bundle?

  A. VRRP

  B. Virtual Chassis

  C. LAG

  D. NSB

  Correct Answer: C

• Question 20:

  You disconnected a switch from the Virtual Chassis, but the disconnected switch's member ID is still

  displayed in the status output.

  Which operational command is used to remove the disconnected member?

  A. request virtual-chassis renumber member-id 3 new-member-id 2

  B. request virtual-chassis vc-port delete pic-slot 2 port 0

  C. request virtual-chassis reactivate

  D. request virtual-chassis recycle

  Correct Answer: D
