Juniper Juniper Certifications JN0-363 Questions & Answers

• Question 31:

  You are asked to configure an LSP which uses the OSPF link state database for path computations. Which two statements are correct in this scenario? (Choose two.)

  A. You must use the no-cspf parameter in the label-switched-path configuration.

  B. Traffic engineering extensions ate enabled by default In OSPF.

  C. Traffic engineering extensions are not enabled by default in OSPF.

  D. You must use the policing parameter in the label-switched-path configuration.

  Correct Answer: AC

  Explanation: The no-cspf command will activate usage of OSPF DB https://www.juniper.net/documentation/us/en/software/junos/ospf/topics/topic- map/configuring-ospf-support-for-traffic-engineering.html Not enabled by default for ospf

• Question 32:

  Which BGP message type is used to re-advertise routes that have already been sent to a peer and acknowledged using TCP?

  A. update

  B. keepalive

  C. notification

  D. refresh

  Correct Answer: D

  Explanation: The BGP (Border Gateway Protocol) refresh message is used to request the re-advertisement of the IPv4 unicast or multicast routing information that was previously sent by the sender to the receiver and acknowledged using TCP. This message helps in refreshing the routes in case of route table changes or to ensure that the receiver has the latest and most accurate routing information.

• Question 33:

  The segment touting SRGB start label Is 10,000 and the SRGB index range is 500. In this scenario, which two statements are correct? (Choose two.)

  A. The first usable label is 10,001.

  B. The last usable label is 10.501.

  C. The last usable label is 10,499.

  D. The first usable label Is 10,000.

  Correct Answer: CD

• Question 34:

  What are two bridging concepts that are used to maintain an Ethernet switching table? (Choose two.)

  A. learning

  B. exporting

  C. aging

  D. timing

  Correct Answer: AC

• Question 35:

  You are bringing a new network online with three MX Series devices enabled for STP. No root bridge priority has been configured. Which statement is true in this scenario?

  A. The device with the lowest MAC address will be elected as the root bridge.

  B. The device with the highest MAC address will be elected as the root bridge.

  C. The device with the lowest numerical lo0 IP address will be elected as the root bridge.

  D. The device with the highest numerical lo0 IP address will be elected as The bridge.

  Correct Answer: A

  Explanation: https://supportportal.juniper.net/s/article/EX-Identify-the-Root-Bridge-in-a- Spanning-Tree-STP-network?language=en_US The root bridge in a spanning-tree network is the bridge with the smallest or the lowest bridge ID.

• Question 36:

  Which statement describes integrated routing and bridging (IRB) interfaces?

  A. An IRB interface Is an IP gateway For hosts of a bridge domain.

  B. An IRB interface assigns interfaces to VLANs.

  C. An IRB interface enables Layer 2 switching on the router.

  D. An IRB interface defines a bridge domain.

  Correct Answer: C

• Question 37:

  Which new field is added to an IPv6 header as compared lo IPv4?

  A. version

  B. checksum

  C. fragment offset

  D. flow label

  Correct Answer: D

• Question 38:

  You want to enable a routing platform with redundant REs to switch from a primary RE to a backup RE without alerting peer nodes. Which two technologies would you use to satisfy this requirement? (Choose two.)

  A. GRES

  B. VRRP

  C. NSR

  D. ISSU

  Correct Answer: BC

• Question 39:

  Which statement is correct about IS-IS?

  A. IS-IS is a distance vector routing protocol.

  B. IS-IS is a path vector routing protocol.

  C. IS-IS is a link-state routing protocol.

  D. IS-IS is a classful routing protocol.

  Correct Answer: C

• Question 40:

  Which two statements ate correct about the BGP next-hop attribute value? (Choose two.)

  A. By default, the next-hop value is changed across IBGP links.

  B. By default, the next-hop value is changed across EBGP links.

  C. By default, the next-hop value is not changed across IBGP links.

  D. By default, the next-hop value is not changed across EBGP links.

  Correct Answer: BC

  Explanation: By default, the router that originally sourced the route into BGP places its peer address into the attribute field. The next-hop value is then typically changed when the route is transmitted across external gGP (EBGP) links. Internal BGP (IBGP) peers do not alter the next-hop value between themselves.
