NEW QUESTION # 17
You want to share routes between two routing instances that you have configured?
What are two ways to accomplish this task? (Choose two.)
- A. Use a RIB group.
- B. Create a forwarding instance.
- C. Use a non-forwarding instance.
- D. Configure an instance import policy
Answer: A,D
Explanation:
static route with a next-hop of next-table pointing to the appropriate routing table which contains more accurate information rib-groups to mirror routing information from one route-table to another. However, in many cases, in order to make this work, interface-routes also need to be mirrored. RIB Group policy can be used to constrain the routing information instance-import and instance-export statements configured within the individual routing-instances to leak routes from one table to another. Again, policy can be used here to constrain the routing information. This method is more straightforward than the rib-group method A final approach is to use physical interfaces or logical-tunnels to stitch routing-instances and use a routing protocol or static routes across this connection between the two routing-instances.
To share routes between two routing instances on a Junos device, you can configure an instance import policy in one or both instances to import routes from the other instance. Alternatively, a RIB (Routing Information Base) group can be used to share routes between instances.

NEW QUESTION # 20
Which configuration selling prohibits a static route from being redistributed by a dynamic routing protocol?
- A. no-readvertise
- B. qualified-next-hop
- C. route-filter
- D. passive
Answer: A
Explanation:
Theno-readvertisepolicy statement is used to prevent a static route from being redistributed into a dynamic routing protocol. This setting ensures that routes that are configured statically are not advertised out via dynamic routing protocols such as OSPF or BGP.

Answer: D
Explanation:
The FE80::/10 prefix is reserved for IPv6 link-local addresses. These addresses are auto-configured on all IPv6-enabled interfaces and can be used for communication within the local link (subnet) only.

NEW QUESTION # 29
The segment touting SRGB start label Is 10,000 and the SRGB index range is 500.
In this scenario, which two statements are correct? (Choose two.)
- A. The last usable label is 10,499.
- B. The first usable label Is 10,000.
- C. The first usable label is 10,001.
- D. The last usable label is 10.501.
Answer: A,C
Explanation:
The Segment Routing Global Block (SRGB) defines a range of MPLS labels reserved for segment routing. With an SRGB starting label of 10,000 and an index range of 500, the first usable label is indeed 10,001 because label 10,000 is typically reserved and not used for forwarding. The last usable label would be 10,499 because the range includes 500 labels starting from 10,001.

NEW QUESTION # 36
You want to save adjacency formation time between two routers participating in OSPF, as well as reduce the size of the OSPF link-state database.
How would you accomplish these tasks?
- A. Define a point-to-point connection.
- B. Specify a designated router.
- C. Configure a virtual link.
- D. Specify a backup designated router.
Answer: A
NEW QUESTION # 37
Click the Exhibit button.
The routers shown in the exhibit are configured for segment routing.
In this scenario, what is the adjacency SID that Router B advertises to Router A?
- A. 10.1.1.2
- B. 0
- C. 10.1.1.1
- D. 1
Answer: A
Explanation:
Currently, Junos OS enables you to configure a SPRING node SID for IPv4 and IPv6 address families for each routing instance. This node SID is attached to an IPv4 and IPv6 router ID if the router ID is configured on the loopback interface. Otherwise, the lowest IP address assigned to the loopback interface is chosen as the node SID. Configuring a node SID through policy allows you to choose the loopback address that gets the node SID. If the node SID configuration exists and a policy is defined for node SID selection for the same prefix, then the policy configuration takes precedence.
