Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q23-Q28):

NEW QUESTION # 23
Exhibit

You are examining an L3VPN route that includes the information shown in the exhibit Which statement is correct in this scenario?

A. The information shows a Type 0 route distinguisher
B. The information shows a Type 1 route distinguisher.
C. The information shows a Type 2 route distinguisher.
D. The information shows a route target

Answer: B

Explanation:
Type 1: When Type value is 1, the Administrator field is 4-bytes and Assigned Number field is 2-bytes. The Administrator field should be set to the IP address (public IP addresses should be used). The Assigned Number field contains a number from a numbering space that is administered by the enterprise to which the IP address has been assigned by the appropriate authority.

NEW QUESTION # 24
Which statement is true regarding BGP FlowSpec?

A. It is used to protect a network from denial-of-service attacks dynamically.
B. It uses a remote triggered black hole to protect a network from a denial-of-service attack.
C. It verifies that the source IP of the incoming packet has a resolvable route in the routing table.
D. It uses dynamically created routing policies to protect a network from denial-of-service attacks.

Answer: A

NEW QUESTION # 25
Refer to the exhibit.

Click the Exhibit button.
Which two statements are correct about the class-of-service configuration shown in the exhibit? (Choose two.)

A. Incoming traffic will not be classified because no classifier exists in the configuration.
B. Incoming traffic will be classified using the default classifier.
C. The best-effort queue can transmit more than 40% of the total bandwidth on the ge-0/0/0 interface, if no other queue is using that bandwidth.
D. The best-effort queue can never transmit more than 40% of the total bandwidth on the ge-0/0/0 interface, even if that bandwidth is available.

Answer: B,C

NEW QUESTION # 26
Which statement is correct about IS-IS when it performs the Dijkstra algorithm?

A. When a new neighbor ID in the tree database matches a router ID in the LSDB, the neighbor ID is moved to the candidate database
B. Tuples with the lowest cost are moved from the tree database to the LSDB.
C. The algorithm will stop processing once the tree database is empty.
D. The local router moves its own local tuples into the candidate database

Answer: D

Explanation:
Explanation
IS-IS is a link-state routing protocol that uses the Dijkstra algorithm to compute the shortest paths between nodes in a network. The Dijkstra algorithm maintains three data structures: a tree database, a candidate database, and a link-state database (LSDB). The tree database contains the nodes that have been visited and their shortest distances from the source node. The candidate database contains the nodes that have not been visited yet and their tentative distances from the source node. The LSDB contains the topology information of the network, such as the links and their costs.
The Dijkstra algorithm works as follows:
* The local router moves its own local tuples into the tree database. A tuple consists of a node ID, a distance, and a parent node ID. The local router's tuple has a distance of zero and no parent node.
* The local router moves its neighbors' tuples into the candidate database. The neighbors' tuples have distances equal to the costs of the links to them and parent node IDs equal to the local router's node ID.
* The local router selects the tuple with the lowest distance from the candidate database and moves it to the tree database. This tuple becomes the current node.
* The local router updates the distances of the current node's neighbors in the candidate database by adding the current node's distance to the link costs. If a shorter distance is found, the parent node ID is also updated.
* The algorithm repeats steps 3 and 4 until either the destination node is reached or the candidate database is empty.

NEW QUESTION # 27
Which two statements are correct regarding bootstrap messages that are forwarded within a PIM sparse mode domain? (Choose two.)

A. Bootstrap messages are forwarded to all routers within a PIM sparse-mode domain.
B. Bootstrap messages distribute RP information dynamically during an RP election.
C. Bootstrap messages are used to notify which router is the PIM RP
D. Bootstrap messages are forwarded only to routers that explicitly requested the messages within the PIM sparse-mode domain

Answer: A,B

Explanation:
Explanation
Bootstrap messages are PIM messages that are used to distribute rendezvous point (RP) information dynamically during an RP election. Bootstrap messages are sent by bootstrap routers (BSRs), which are routers that are elected to perform the RP discovery function for a PIM sparse-mode domain. Bootstrap messages contain information about candidate RPs and their multicast groups, as well as BSR priority and hash mask length. Bootstrap messages are forwarded to all routers within a PIM sparse-mode domain using hop-by-hop flooding.
