NEW QUESTION # 64
You are configuring an aggregate route. In this scenario, which two statements are correct? (Choose two.)

  • A. Reject will silently drop the traffic.
  • B. Discard will silently drop the traffic.
  • C. Discard will send an ICMP Destination Unreachable message back to the sender.
  • D. Reject will send an ICMP Destination Unreachable message back to the sender.

Answer: B,D

Explanation:
When configuring anaggregate route, you have options for how to handle traffic that matches the route but does not match any more specific route in the routing table. Two actions can be taken:discardandreject.
Step-by-Step Breakdown:
* Discard:
* Thediscardoption will silently drop packets that match the aggregate route. No notification is sent to the sender, and the packet is simply dropped.
* Reject:
* Therejectoption will drop the packet and also send anICMP Destination Unreachablemessage back to the sender. This informs the sender that the packet could not be delivered because there is no specific route available.
Juniper Reference:
* Aggregate Routes: The reject and discard next-hop options provide different levels of feedback when packets cannot be routed, and they can be used to control how unreachable destinations are handled.


NEW QUESTION # 65

  • A. Area Border Router (ABR)
  • B. Internal Router
  • C. Backbone Router
  • D. Autonomous System Boundary Router (ASBR)

Answer: D


NEW QUESTION # 66
Exhibit:

R2 received an OSPF update from R1, and it received the same update from R3.
Referring to the exhibit, what will R2 do?

  • A. R2 does nothing with R3's update.
  • B. R2 ignores the update from R3.
  • C. R2 acknowledges R3 and discards it.
  • D. R2 ignores the update from R1.

Answer: B

Explanation:
In the exhibit, R2 receives the same OSPF update from both R1 and R3. OSPF has mechanisms toprevent unnecessary processing of duplicate LSAs (Link-State Advertisements).
Step-by-Step Breakdown:
* OSPF LSA Processing:
* OSPF uses LSAs to exchange link-state information between routers. When a router receives an LSA, it checks if it already has a copy of the LSA in its Link-State Database (LSDB).
* Duplicate LSAs:If R2 has already received and processed the update from R1, it willignore the update from R3because it already has the same LSA in its database. OSPF uses the concept of flooding, but it does not reprocess LSAs that it already knows about.
* R2 Behavior:R2 will keep the update from R1 (the first one it received) and will ignore the same LSA from R3, as it is already in the LSDB.
Juniper Reference:
* OSPF LSA Processing: Junos adheres to OSPF standards, ensuring that duplicate LSAs are not processed multiple times to avoid unnecessary recalculations.
