11. You have configured the router with an IS-IS interface metric of 2048.

However, the IS-IS interface metric of 63 is being applied for the interface of this router.

What must you do to enable the larger metric value?

Enable wide metrics.

Disable narrow metrics.

Restart the IS-IS protocol.

13. You are adding a new EX4300 member switch to your existing EX4300 Virtual Chassis. However, the new member is not running the same Junos version as the other members.

By default, what is the expected behavior in this scenario?

the Virtual Chassis will transition into a split brain situation between the existing master Routing Engine and the switch running the different version.

The new switch will automatically pull the correct version from the master Routing Engine and perform the necessary upgrade.

The new switch will be assigned a member ID and then placed in an inactive state.

The new switch is not recognized by the Virtual Chassis.

14. You are enabling dynamic ARP inspection on an EX4300 switch.

Which service is enabled by default in this scenario?

DHCP snooping

persistent MAC learning

MAC limiting

IP Source Guard

15. Click the Exhibit button.

Referring to the exhibit, Router-1 and Router-2 are failing to form an IS-IS adjacency.

What should you do to solve the problem?

Remove the overloaded statement from Router-1.

Change the IP subnet masks to match on the ge-0/0/2 interfaces of both routers.

Change the ISO areas on the lo0 interfaces to match on both routers.

Remove the ISO address from ge-0/0/2 on Router-1.

16. You want to use filter-based forwarding (FBF) to forward traffic sourced from subnet 10.0.0.0/24 to a specific destination.

Which two routing instance types would enable you to accomplish this task? (Choose two.)

virtual switch

virtual routing and forwarding

virtual router

forwarding

17. Which statement is true about IP-IP tunnels?

The time-to-live value of the original packet is decremented.

IP-IP tunnels are protocol agnostic.

The packet is encapsulated unchanged before entering the tunnel.

The packet header is replaced before entering the tunnel.

18. Click the Exhibit button.

Referring to the exhibit, which policy will export routes to IBGP peers?

static-3

static-4

static-1

static-2

19. Click the Exhibit button.

You manage the Layer 2 network shown in the exhibit. You experience a failure on the ge-0/0/0 link between Switch-1 and Switch-2.

Which statement is correct about the expected behavior?

Switch-2 will remove itself from the RSTP topology

Switch-2’s ge-0/0/2 port role and state will transition to root and forwarding

Switch-2 will become the root bridge for a separate RSTP topology

Switch-2’s ge-0/0/2 port role and state will remain as designated and forwarding

20. Which two routes belong to the 172.16.0.0/22 aggregate route? (Choose two.)

172.16.4.0/24

172.16.0.0/24
