• Question 273:

  Which OSPF LSA type describes the router IDs of ASBR routers located in remote areas?

  A. Type 4
  B. Type 2
  C. Type 3
  D. Type 1
  A. Type 4

• Question 274:

  Two Junos devices are trying to form an OSPF adjacency. When you issue the "show ospf neighbor" command, you see that one device is in the Loading state and the other is in the Full state. Why is one device in the Loading state?

  A. The device does not know about the received LSA header and has transmitted a link-state request
  B. The device has finished transmitting, but is still receiving database information
  C. The device is waiting for a start event
  D. The device has established bidirectional communication with its peer
  B. The device has finished transmitting, but is still receiving database information

  Referring to the exhibit, R1 and R2 are directly connected using interface ge-1/1/0.

  What is the reason the IS-IS adjacency fails?

  A. R2 has an MTU value of 1496 configured on ge-1/1/0.
  B. R2 and R1 have different area IDs.
  C. R1 is configured for Level 2, and R2 is configured for Level 1.
  D. R1 is configured for both Level 1 and Level 2 to be disabled.
  B. R2 and R1 have different area IDs.

• Question 276:

  You observe that VPN routes are hidden on your PE router Which situation accounts for these hidden routes?

  A. The protocol next-hop is not found in inet.3
  B. The protocol next-hop is not found in mpls 0
  C. The protocol next-hop is not found in bgp I3vpn 0
  D. The protocol next-hop is not found in inet 2
  A. The protocol next-hop is not found in inet.3

• Question 277:

  You have recently installed a second Routing Engine (RE) in your router

  Which two statements correctly describe the expected behavior if the primary RE fails? (Choose two.)

  A. The backup RE will assume the master role once the packet forwarding engine restarts
  B. The backup RE will immediately assume the master role
  C. The new master RE restarts the routing protocol process (rpd) and establishes any required adjacencies based on the configuration.
  D. The new master RE maintains the existing protocol adjacencies initially established by the previous master RE
  A. The backup RE will assume the master role once the packet forwarding engine restarts
  C. The new master RE restarts the routing protocol process (rpd) and establishes any required adjacencies based on the configuration.

• Question 278:

  Which two statements correctly describe how the AS path attribute is used by BGP? (Choose two.)

  A. The AS path attribute is updated whenever an EBGP-learned route is re-advertised using IBGP.
  B. The AS path attribute is updated in EBGP advertisements only and is the primary loop-avoidance mechanism for BGP.
  C. When local preference is the same, the AS path attribute is a common tiebreaker, where paths with fewer AS hops are preferred.
  D. When local preference is the same, the AS path attribute is a common tiebreaker, where paths with more AS hops are preferred.
  B. The AS path attribute is updated in EBGP advertisements only and is the primary loop-avoidance mechanism for BGP.
  C. When local preference is the same, the AS path attribute is a common tiebreaker, where paths with fewer AS hops are preferred.
