JNCIP-SP JN0-664 Practice Questions & Answers • ExamPrepare

Question 1

CE-1 and CE-2 are part of a VPLS called Customer1. No connectivity exists between CE-1 and CE-2. In the process of troubleshooting, you notice PE-1 is not learning any routes for this VPLS from PE-2, and PE-2 is not learning any routes for this VPLS from PE-1.

Referring to the exhibit, which statement is correct?

The instance type should be changed to l2vpn .
The route distinguisher must match on PE-1 and PE-2.
The route target must match on PE-1 and PE-2.
The no-tunnel-services statement should be deleted on both PEs.

Question 2

Which two statements are true about the OSPF adjacency displayed in the exhibit? (Choose two.)

There is a mismatch in the dead interval parameter between routers R1 and R2.
There is a mismatch in the poll interval parameter between routers R1 and R2.
There is a mismatch in the hello interval parameter between routers R1 and R2.
There is a mismatch in the OSPF hold timer parameter between routers R1 and R2.

Question 3

multipath

route-target

add-path

multihop

Referring to the exhibit, you are receiving the 192.168.0.0/16 route on both R3 and R4 from your EBGP neighbor. You must ensure that R1 and R2 receive both BGP routes from the route reflector.

In this scenario, which BGP feature should you configure to accomplish this behavior?

add-path
multipath
route-target
multihop

Question 4

A packet is received on an interface configured with transmission scheduling. One of the configured queues is exceeding the allocated bandwidth.

In this scenario, which two actions will be taken by default on a Junos device? (Choose two.)

The excess traffic will be discarded.
The excess traffic will use bandwidth available from other queues.
The exceeding queue will be considered to have positive bandwidth credit.
The exceeding queue will be considered to have negative bandwidth credit.

Question 5

Which two statements are correct about IS-IS interfaces? (Choose two.)

If a point-to-point interface is in both L1 and L2, separate hello messages are sent for each level.
If a point-to-point interface is in both L1 and L2, one combined hello message is sent for both levels.
If a broadcast interface is in both L1 and L2, separate hello messages are sent for each level.
If a broadcast interface is in both L1 and L2, one combined hello message is sent for both levels.

Question 6

user@router> show l2vpn connections

Layer-2 VPN connections:

Legend for connection status (St)

EI -- encapsulation invalid NC -- interface encapsulation not CCC/TCC/VPLS

EM -- encapsulation mismatch WE -- interface and instance encaps not same

VC-Dn -- Virtual circuit down NP -- interface hardware not present

CM -- control-word mismatch -> -- only outbound connection is up

CN -- circuit not provisioned <- -- only inbound connection is up

OR -- out of range Up -- operational

OL -- no outgoing label Dn -- down

LD -- local site signaled down CF -- call admission control failure

RD -- remote site signaled down SC -- local and remote site ID collision

LN -- local site not designated LM -- local site ID not minimum designated

RN -- remote site not designated RM -- remote site ID not minimum designated

XX -- unknown connection status IL -- no incoming label

MM -- MTU mismatch MI -- Mesh-Group ID not available

BK -- Backup connection ST -- Standby connection

PF -- Profile parse failure PB -- Profile busy

RS -- remote site standby SN -- Static Neighbor

LB -- Local site not best-site RB -- Remote site not best-site
