Question 2
Click the Exhibit button.
Referring to the exhibit, which two statements are true? (Choose two.)
- The BGP peering between R1 and R4 should use loopback interface addresses
- The BGP peering between R1 and R4 should use physical interface addresses
- The BGP peerings between R1, R2, and R3 should use loopback interface addresses
- The BGP peerings between R1, R2, and R3 should use physical interface addresses
Correct answer: BC
Question 3
Click the Exhibit button.
Referring to the exhibit, which statement about the IS-IS interface is true?
- The ge-0/0/0.0 interface will act as an L1/L2 interface
- The ge-0/0/0.0 interface will act as an L2 interface only
- The ge-0/0/0.0 interface will act as an L1 interface only
- The ge-0/0/0.0 interface will not be assigned to a level
Correct answer: A
Question 4
Click the Exhibit button.
Referring to the exhibit, why is the route hidden?
- The wrong BGP address family is enabled for the BGP session
- The route has yet to be verified
- The protocol next hop is not reachable
- The MPLS LSP to the 192.168.0.2 peer is down
Correct answer: C
Question 5
Click the Exhibit button.
Referring to the exhibit, which statement is true?
- The router will attempt to signal the LSP along the IGP shortest path to 192.168.100.1
- The router will prune links with insufficient bandwidth from the path before beginning the signaling process
- The router will analyze the traffic engineering database to determine the best path through the network
- The router will precalculate a valid path through the network for LSP r1-to-r3
Correct answer: B
Question 6
Which two statements are true for GRE tunneling? (Choose two.)
- GRE tunnel endpoints must have a valid route to the remote endpoint
- GRE tunnels support multiple logical units per interface
- GRE tunnels are stateful by default
- GRE tunnels support only one logical unit per interface
Correct answer: AB

Question 7
Click the Exhibit button.
Referring to the exhibit, the GRE tunnel between R-1 and R-2 allows connectivity between User-1 and Server-1. When User-1 communicates with Server-2 with packets that are 1472 bytes in size, no packet fragmentation occurs. User-1 can communicate with Server-1 with packets that are up to 1448 bytes in size with no packet fragmentation. However, if the packet size is larger than 1448 bytes, packet fragmentation occurs.
Why is the packet fragmentation occurring between User-1 and Server-1 in this scenario?
- The GRE header adds 20 bytes to the packet
- The GRE header adds 24 bytes to the packet
- The IP header adds 20 bytes to the packet
- The IP header adds 24 bytes to the packet
Correct answer: B
Question 8
What happens when a packet matches a static route with the next hop parameter set to reject?
- The system silently drops the packet
- An ICMP message is sent to the source and the packet is forwarded
- An ICMP message is sent to the source and the packet is dropped
- The packet is forwarded and the packet is marked as rejected in the header
Correct answer: C

Question 9
Which two statements are correct about the BGP MED attribute? (Choose two.)
- BGP uses the MED value when peering to two or more connections to the same upstream AS
- BGP routes require the MED attribute be defined
- BGP uses the MED value when peering to two different upstream ASs
- BGP assumes the MED value to be 0, if not already defined
Correct answer: AD

Question 10
What is the Junos default router priority advertisement value for IS-IS?
- 64
- 32
- 0
- 127
