Routing Table for User-Defined Routing Instance Candidate1

B

In Juniper Networks, routing tables are used to store and manage routing information. Each routing table corresponds to a specific routing instance, which can be associated with a virtual network or a specific routing protocol. When packets are forwarded through a router, the router consults the appropriate routing table to determine the best path to the destination network.

In this question, we are asked to determine which routing table contains the route information for the user-defined routing instance called Candidate1. The available answers are:

A. inet.Candidate1.0 B. Candidate1.inet.0 C. inet.0 D. Candidate1-inet.0

Let's examine each answer in turn:

A. inet.Candidate1.0: This answer implies that there is a routing table called Candidate1.0 that is a sub-table of the inet routing table. However, the correct syntax for referring to a routing instance in Juniper Networks is "routing-instance-name.inet". Therefore, this answer is not valid.

B. Candidate1.inet.0: This answer correctly uses the syntax for referring to a routing instance in Juniper Networks. It specifies that the routing table we are looking for is called "inet.0" and belongs to the "Candidate1" routing instance. This is the correct answer.

C. inet.0: This answer refers to the default routing table, which contains the routes learned from all the routing protocols running on the router. It does not specify the routing instance, so it is not the correct answer.

D. Candidate1-inet.0: This answer suggests that the routing table we are looking for is a sub-table of the Candidate1 routing instance, but it uses the incorrect syntax. The correct syntax would be "routing-instance-name-inet.0". Therefore, this answer is not valid.

In conclusion, the correct answer to this question is B. Candidate1.inet.0.
