1. Which statement is true about an OSPF broadcast link?

All routers form an adjacency only with the BDR

All routers form an adjacency only with the DR

All routers form an adjacency with all other routers

All routers form an adjacency with both the DR and BDR

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

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

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

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

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

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

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

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

10. What is the Junos default router priority advertisement value for IS-IS?

127

11. Which three attributes are well-known mandatory BGP attributes? (Choose three.)

next-hop

AS path

local preference

MED

origin

12. Click the Exhibit button.

Referring to the exhibit, which statement is correct?

Interface ge-3/0/0.0 has a default metric of 10

Interface xe-0/0/0.0 can only form a single adjacency

Interface xe-0/0/0.0 has a default metric of 10

Interface ge-1/0/0.0 can only form a single adjacency

13. Click the Exhibit button.

You have configured IPv6 over IPv4 tunneling, as shown in the exhibit. However, hosts connected to network 2001:0:0:1::0/64 cannot communicate with hosts on network 2001:0:0:2::0/64. The router R2 has a similar configuration as the R1 router.

How would you solve this problem?

Configure an IGP across the tunnel interfaces

Configure an IPv6 address on the tunnel interfaces

Configure the next hop of the inet6.0 static route to point to the physical interface between the routers

Configure the next hop of the inet6.0 static route to point to the IPv4 address of the remote router

14. In a stateless IPv6 auto-configuration scenario, what is the host’s IPv6 address if the interface’s MAC address is 12:34:ab:cd:ef:56?

fe80::1234:abff:fecd:ef56/64

fe8::1234:abff:fecd:ef56/64

fec0::1234:abff:fecd:ef56/64

fe80::1234:abcd:ef56/64

15. Click the Exhibit button.

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

The router will install the 0.0.0.0/0 route into the routing table when no BGP prefixes are present

The router will remove the 0.0.0.0/0 route from the routing table when no BGP prefixes are present

The router will remove the 0.0.0.0/0 route from the routing table when any BGP prefixes are present

The router will install the 0.0.0.0/0 route into the routing table when any BGP prefixes are present

16. Click the Exhibit button.

Both configuration hierarchies shown in the exhibit have been committed to your MX Series device.

Which two statements are true in this scenario? (Choose two.)

Traffic destined to 10.3.0.1 will use the R1-to-R6LSP as a next hop

Traffic destined to 10.3.0.1 will not use the R1-to-R6LSP as a next hop

The active 10.3.0.0/24 prefix installed in the route table will have a route preference of 5

The active 10.3.0.0/24 prefix installed in the route table will have a route preference of 7

17. You are asked to change the default TTL handling behavior on your Junos device to ensure that the RSVP-signaled LSPs in your MPLS network cannot be mapped.

Which configuration should be performed to accomplish this task?

Configure the no-decrement-ttlparameter for each LSP on the ingress device

Configure the no-propagate-ttlparameter for each LSP on the egress device

Configure the no-propagate-ttlparameter for each LSP on the ingress device

Configure the no-decrement-ttlparameter for each LSP on the egress device
