Question 1 of 136

Which two statements describe aggregate routes? (Choose two.)

Invalid routing prefixes are not advertised to external peers.

Internal routing instabilities can be hidden from external peers

Groups of routes are combined into a single route entry.

The route receives the next hop of the primary contributing route.

Correct Answer: B, C

Aggregate routes help in summarizing multiple routes into a single route entry, which helps in reducing the size of routing tables. By combining several specific routes into one aggregate route, internal routing instabilities are hidden from external peers. This means that routing issues within a network do not propagate to external peers, promoting stability. Therefore, the correct answers are that internal routing instabilities can be hidden from external peers and groups of routes are combined into a single route entry.

Question 2 of 136

You are configuring a new BGP service to your service provider. You want to ensure that BGP is fully established and has all the routes in the route table before allowing traffic to transit the router.
Which feature achieves this requirement?

BGP route reflector

IS-IS mesh group

BGP local preference

IS-IS overload bit

Correct Answer: D

To achieve the requirement of ensuring that BGP is fully established and has all the routes in the route table before allowing traffic to transit the router, the IS-IS overload bit is the correct feature. This feature can temporarily prevent the router from being used for transit traffic until it has fully synchronized its BGP routes. It tells other routers in the network to avoid using this router for transit traffic until it is ready, thereby ensuring the desired state is met before traffic is allowed to pass through.

Question 3 of 136

Which LSA type describes the router ID of ASBR routers located in remote areas?

Type 4

Type 5

Type 3

Type 7

Question 4 of 136

Which two statements are true about Virtual Chassis? (Choose two.)

It is possible to automatically update the Junos OS on newly added members to participate in the Virtual Chassis

A software version mismatch on a newly added member must be placed in linecard mode.

Virtual Chassis members use VCCP to create a loop-free topology.

The member ID is not preserved through reboots.

Correct Answer: A, C

Exam JN0-347: Question 5 - Image 1

You are monitoring your IS-IS router and issue the command shown in the exhibit.
Which two statements are true in this scenario? (Choose two.)

The loopback address of the local router is 5.0.0.100.

The loopback address of the local router is 10.100.0.1.

The name of the remote device is r1.

The name of the local device is r1.

Correct Answer: B, D

The loopback address of the local router is 10.100.0.1, which is indicated by the IP address shown next to 'IP router id' and 'IP address'. The name of the local device is r1, which is stated next to 'Hostname'. The other address, 5.0.0.100, is identified as the IS-extended neighbor and not the loopback address of the local router.
