OSFP is stuck in the ExStart state.
What is a common cause of this problem?

• A.The DR priority is configured incorrectly.
• B.IP addresses are not configured correctly.
• C.MTUs do not match.
• D.Jumbo frames are not enabled.

Which two statements are correct about using LLDP on junos devices? (Choose two.)

• A.LLDP is enabled on all devices by default
• B.LLDP operates on layer 2 and layer 3 interfaces
• C.LLDP can interoperate with the cisco discovery protocol CDP
• D.LLDP operates on layer 2 interfaces

Referring to the exhibit, you have EBGP peerings with both ISP1 and ISP2. You are receiving the
172.25.12.0/24, 172.25.13.0/24, 172.25.14.0/24, and 172.25.15.0/24 routes through both neighbors. You must ensure that traffic to these prefixes are load balances through both service providers. You have configured a load-balancing policy and have applied it to the forwarding table, but the prefixes are not being load balanced.
What is required to accomplish this task?

• A.The include-mp-next-hop feature should be used between both neighbors.
• B.The multipath multiple-as feature should be used between both neighbors.
• C.The multihop feature should be enabled between both neighbors.
• D.The as-override feature should be used between both neighbors.

You have deployed Sparse Mode multicast in your network using the IGP metrics shown in the exhibit.
Which path will (*, G) traffic follow form the source to the receiver before the (S, G) state is registered?

• A.Source, R1, R2, R5, R2, R3, R6 Receiver
• B.Source, R1, R4, R5, R6, Receiver
• C.Source, R1, R2, R3, R6, Receiver
• D.Source, R1, R2, R5, R6, Receiver

You are configuring dynamic rendezvous points for your PIM multicast domain. You have chosen to use auto-RP as the dynamic RP mechanism. You are not seeing the auto-RP announcements.
Referring to the exhibit, which two configurations will solve this problem? (Choose two.)

• A.Configure the rp for the mapping function.
• B.Configure the interfaces for sparse-dense mode.
• C.Configure the dense-groups for addresses 224.0.1.39 and 224.0.1.40.
• D.Configure the interfaces for sparse mode.
