• Question 411:

  Click the Exhibit button

  

  When the Junos configuration shown in the exhibit is applied to the router, which routes in the forwarding table will begin load-balancing packet flows?

  A. all routes in the forwarding table

  B. all OSPF routes in the forwarding table

  C. all BGP routes in the forwarding table

  D. all RFC1918 routes in the forwarding table

  Correct Answer: D

• Question 412:

  You have configured MPLS and RSVP in your network using all of the Junos defaults. You established an LSP in your network which is reporting an up status but no traffic is using it.

  Which two statements reflect potential causes for this issue? (Choose two)

  A. The LSP egress address is a physical interface address

  B. family MPLS was omitted from the router configurations

  C. No BGP routes are being advertised from the remote neighbor

  D. The LSP egress address does not match the BGP next-hop address

  Correct Answer: CD

• Question 413:

  Using industry best practices, what is true regarding an external BGP session?

  A. BGP neighbors belong to the same AS

  B. BGP neighbors belong to a different AS

  C. BGP sessions rely on a static route for reach ability

  D. BGP sessions will be established between loopback interface addresses.

  Correct Answer: C

• Question 414:

  You own a home network connecting through an always-on connection and need to assign IPv6 addresses to your routers because you want to follow the guidelines spelled out in RFC 3177. You want to design your network with the correct prefixes.

  Which prefix would your ISP likely allocate to your network?

  A. 47-bit prefix

  B. 48-bit prefix

  C. 64-bit prefix

  D. 128-bit prefix

  Correct Answer: B

  From RFC 3177: This document provides recommendations to the addressing registries (APNIC, ARIN and RIPE-NCC) on policies for assigning IPv6 address blocks to end sites. In particular, it recommends the assignment of /48 in the general case, /64 when it is known that one and only one subnet is needed and /128 when it is absolutely known that one and only one device is connecting.

• Question 415:

  Click the Exhibit button In the exhibit, OSPF routers R1, R2, R3, and R4 come up, in order, at 1-minute intervals Which router will be the designated router?.

  

  A. R1

  B. R2

  C. R3

  D. R4

  Correct Answer: A

• Question 416:

  You have been asked to configure an IPv6 address for a group of interfaces that could belong on different routers. If a packet is sent to that address, it should be received by all routers in the group.

  Which address type would be suited for these requirements?

  A. Unicast

  B. Multicast

  C. Anycast

  D. Broadcast

  Correct Answer: B

• Question 417:

  What is the function of the hop limit field in the IPv6 header?

  A. It limits the diameter of the network to 20 hops

  B. It sets the number of hops in the network to be equal to the MPLS header time-to-live (TTL)

  C. It replaces the time-to-live (TTL) field in IPv4

  D. It represents future extensibility to the protocol

  Correct Answer: C

• Question 418:

  Click the Exhibit button

  

  You work for the regional Internet service provider shown in the exhibit You have a partial BGP table and are receiving a 10 100/16 route from your upstream ISP You have been asked to configure a default route that can be sent to your downstream customer This route should forward customer traffic toward your upstream Tier 11SP as long as the 10.100/16 route is present.

  What would accomplish this goal?

  A. Create and announce an aggregate default route

  B. Create and announce a static default route with a next-hop of discard

  C. Create and announce a static default route with a next-hop of reject

  D. Create and announce a generated default route

  E. Create an advertise-map with exist-map

  Correct Answer: E

• Question 419:

  Click the Exhibit button

  

  Referring to the network illustrated in the exhibit, how does router A reach destinations in area 49.2222?

  A. Router A will use the routes from area 49.2222; it learns from router B

  B. Router A will see the attached bit from router B and create a default route

  C. Router A must have a default route manually configured

  D. Router A will receive a default route in the IS-IS update from router B

  Correct Answer: B

• Question 420:

  You have recently implemented a graceful Routing-Engine switchover (GRES) and want to further reduce down time if a Routing Engine (RE) failure occurs.

  Which two features can be configured on this device to reduce its downtime in this situation? (Choose two)

  A. VRRP

  B. GR

  C. BFD D. NSR

  Correct Answer: BD
