NEW QUESTION # 63
Which OSPF database packet determines which router is in charge of the database synchronization and the transferring of LSA headers between the two systems?
- A. link-state update
- B. link-state request
- C. hello
- D. database description
Answer: D
Explanation:
the Database Description (DD) packets serve two main purposes:
1. determinining which router is in charge of the database synchronization
2. tansferring the LSA headers between the two systems
The Database Description (DBD) OSPF packet is used during the adjacency formation process to describe the contents of the topological database between routers. The routers exchange DBD packets to determine the master and slave relationship, which dictates the router in charge of the database synchronization.

You are asked to configure filter-based forwarding on a Junos device.
Which two statements are correct in this scenario? (Choose two.)
- A. You must create a routing instance.
- B. You must create and apply a match filter.
- C. You must create a routing policy.
- D. You must create a route target.
Answer: A,B
Explanation:
To configure filter-based forwarding, perform the following tasks: Create a match filter on the ingress device. To specify a match filter, include the filter filter-name statement at the [edit firewall] hierarchy level. A packet that passes through the filter is compared against a set of rules to classify it and to determine its membership in a set. Once classified, the packet is forwarded to a routing table specified in the accept action in the filter description language. The routing table then forwards the packet to the next hop that corresponds to the destination address entry in the table. Create routing instances that specify the routing table(s) to which a packet is forwarded, and the destination to which the packet is forwarded at the [edit routing-instances] hierarchy level.
