The policy shown in the exhibit is applied as an export policy to your BGP neighborship.
Which action will be taken for route 12.233.45.5?
Answer : C
Generally, a router compares a route against the match conditions of each term in a routing policy, starting with the first and moving through the terms in the order in which they are defined, until a match is made and an explicitly configured or default action of accept or reject is taken. If none of the terms in the policy match the route, the router compares the route against the next policy, and so on, until either an action is taken or the default policy is evaluated.

Referring to the exhibit, you must advertise the 100.0.0.0/16 routes from AS1 to AS2, but R2 is not advertising any BGP routes to R5.
Why is this happening in this scenario?
Answer : B
Default BGP Export Policy:
Readvertise all active BGP routes to all BGP speakers, while following protocol-specific rules that prohibit one IBGP speaker from readvertising routes learned from another IBGP speaker, unless it is functioning as a route reflector.

Referring to the exhibit, the source is currently sending multicast traffic using group 224.1.1.1, which is being received by R1. R2 is not receiving PIM register messages.
What would be the cause of this problem?
Answer : A
The multicast traffic being sent by the source must be encapsulated into a PIM register packet. If the tunneling services under the chassis stanza is not configured, a PE (PIM Encapsulation interface) will not be present in the multicast first hop router. Anyway long story short, tunneling services must be turned on or else you will not get PIM register messages sent to the RP.

You have configured and applied the policer shown in the exhibit to your Junos device.
Which statement is true in this scenario?
Answer : B
Red---Traffic that exceeds the burst size for peak traffic (EBS), single-rate marks packets with an implicit loss priority of high and, optionally, discards the packets.
When configuring 802.1X authentication, what are three server fail fallback settings? (Choose three.)
Answer : B, C, E
Permit authentication, allowing traffic to flow from the end device through the interface as if the end device were successfully authenticated by the RADIUS server.
Deny authentication, preventing traffic from flowing from the end device through the interface. This is the default.
Move the end device to a specified VLAN if the switch receives a RADIUS access-reject message. The configured VLAN name overrides any attributes sent by the server. (The VLAN must already exist on the switch.)
Sustain authenticated end devices that already have LAN access and deny unauthenticated end devices. If the RADIUS servers time out during reauthentication, previously authenticated end devices are reauthenticated and new users are denied LAN access.
