Juniper Juniper Certifications JN0-363 Questions & Answers

• Question 71:

  You are troubleshooting two OSPF routers that have an adjacency that remains in the ExStart state.

  What would cause this problem?

  A. mismatched OSPF hello intervals on the OSPF interfaces

  B. mismatched authentication settings on the OSPF interfaces

  C. mismatched MTU settings on the OSPF interfaces

  D. mismatched subnet settings on the OSPF interfaces

  Correct Answer: C

  Explanation: https://www.cisco.com/c/en/us/support/docs/ip/open-shortest-path-first- ospf/13684-12.html#anc13 Neighbors Stuck in Exstart/Exchange State The problem occurs most frequently when you attempt to run OSPF between a Cisco router and another vendor router. The problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces do not match. If the router with the higher MTU sends a packet larger that the MTU set on the neighboring router, the neighbor router ignores the packet. When this problem occurs, the output of the show ip ospf neighbor command displays output similar to what is shown in this figure.

• Question 72:

  Exhibit

  

  Which two statements are correct about the service provider MPLS network shown in the exhibit? (Choose two.)

  A. R3 is considered a P router.

  B. R3 is considered a PE router.

  C. R3 is considered a transit router.

  D. R3 is considered an ingress router.

  Correct Answer: AC

• Question 73:

  Exhibit

  

  Referring to the exhibit, which statement is true about VRRP?

  A. VRRP communication between the two devices is not functioning correctly.

  B. Both routers are in the same state because they have the same VRRP priority.

  C. RRP Is functioning normally in active/active mode.

  D. The routers should use different virtual IP addresses for VRRP to function correctly.

  Correct Answer: D

• Question 74:

  You have created a routing instance named vr3 that will provide access to Server 2 (10.0.0.2) (or the hosts on the 10.10.10.0/24 network. Which command would you use to test connectivity between vr3 and Server 2?

  A. user@vr3> ping 10.0.0.2 count 5

  B. user@vr3> ping 10.0.0.2 count 5 source 10.10.10.1

  C. user9router1> ping 10.0.0.2 count 5

  D. user@router1> ping 10.0.0.2 routing-instance vr3 count 5

  Correct Answer: C

• Question 75:

  Exhibit Referring to the exhibit, which two statements are correct? (Choose two.)

  

  A. Prefixes in Level 1 will be redistributed to Level 2.

  B. Prefixes in Level 2 will be not redistributed to Level 1.

  C. Prefixes in Level 1 will not be redistributed to Level 2.

  D. Prefixes in Level 2 will be redistributed to Level 1.

  Correct Answer: AB

  Explanation: By default, IS-IS protocol leaks routing information from a Level 1 area to a Level 2 area. However, to leak routing information from a Level 2 area to a Level 1 area, an export policy must be explicitly configured.

• Question 76:

  Which statement is correct about the FE80;:/10 prefix?

  A. This prefix range is used for the link local address.

  B. This prefix range is used on the loopback interface.

  C. This prefix range is reserved for multicast applications

  D. This prefix range is not reserved.

  Correct Answer: A

• Question 77:

  When would you use the qualified-next-hop statement with a static route?

  A. You can use it to install the static route into different routing tables.

  B. You can use it to send unwanted traffic to a null route.

  C. You can use it to specify multiple next hops with different preferences.

  D. You can use it to resolve the next hop if the next hop is not directly connected.

  Correct Answer: C

  Explanation: https://www.juniper.net/documentation/us/en/software/junos/static- routing/topics/ref/statement/qualified-next-hop-edit-routing-options.html https://www.juniper.net/documentation/us/en/software/junos/static-routing/topics/topicmap/static-route-prefer-qualified-next-hop.html: Qualified next hops allow you to associate one or more properties with a particular next-hop address. You can set an overall preference for a particular static route and then specify a different preference for the qualified next hop. For example, suppose two next-hop addresses (10.10.10.10 and 10.10.10.7) are associated with the static route 192.168.47.5/32. A general preference is assigned to the entire static route, and then a different preference is assigned to only the qualified next-hop address 10.10.10.7. For example:

• Question 78:

  Which two steps are required to enable MPLS on a physical interface in Junos? (Choose two.)

  A. Add family mpls on the interface.

  B. Add the loopback interface under protocols mpls.

  C. Add family mpls on the loopback interface.

  D. Add the interface under protocols mpls.

  Correct Answer: AD

• Question 79:

  Which two statements are correct about the way that BGP propagates routes by default? (Choose two.)

  A. A route learned by EBGP will be re-advertised to IBGP peers.

  B. A route learned by IBGP will not be re-advertised lo IBGP peers.

  C. A route learned by EBGP will not be re-advertised to IBGP peers.

  D. A route learned by IBGP will be re-advertised to IBGP peers.

  Correct Answer: AB

• Question 80:

  Which two statements are correct about the behavior of IS-IS metrics? (Choose two.)

  A. Wide metrics enable interfaces to advertise metrics larger than 63.

  B. By default, the metric of an interface is calculated based on the speed of the interface.

  C. Wide metrics enable an interface to advertise different metrics at Level 1 and Level 2.

  D. By default, all physical interfaces have a metric of 10.

  Correct Answer: AD

  Explanation: https://www.juniper.net/documentation/us/en/software/junos/is- is/topics/ref/statement/metric-edit-protocols-isis.html

  metric--Metric value.

  Range: 1 through 63, or 1 through 16,777,215 (if you have configured wide metrics)

  Default: 10 (for all interfaces except lo0), 0 (for the lo0 interface)
