Question 4

Referring to the output shown in the exhibit, which two statements are true?

A. The route is not active B. The route is an aggregate route C. The route is active D. The route is a generate route

Correct Answer: C,D

Question 5

You are using OSPF to advertise the subnets that are used by the Denver and Dallas offices. The routers that are directly connected to the Dallas and Denver subnets are not advertising the connected subnets.
Referring to the exhibit, which two statements are correct? (Choose two.)

A. Configure and apply a routing policy that redistributes the connected Dallas and Denver subnets. B. Enable the passive option on the OSPF interfaces that are connected to the Dallas and Denver subnets. C. Configure and apply a routing policy that redistributes the Dallas and Denver subnets using Type
5 LSAs. D. Create static routes on the switches using the local vMX router's loopback interface for the next hop.

Question 6

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?

A. Remove the ISO address from ge-0/0/2 on Router-1. B. Change the ISO areas on the lo0 interfaces to match on both routers. C. Remove the overloaded statement from Router-1. D. Change the IP subnet masks to match on the ge-0/0/2 interfaces of both routers.

Correct Answer: A

Question 7

Your company has a branch location that uses a Juniper Networks EX Series Switch. You are asked to troubleshoot a spanning-tree issue that keeps reoccurring within the branch environment. After investigation, you discover that end-devices running a virtualization application are generating BPDUs, which are disrupting the spanning-tree topology and causing periodic outages. Which solution will prevent this problem from reoccurring?

A. Configure BPDU protection on all edge interfaces. B. Disable RSTP on all access interfaces. C. Increase the max-age timer on all EX Series Switches. D. Configure root protection on all access interfaces.

Question 8

You want to use filter-based forwarding (FBF) on your Internet peering router to load-balance traffic to two directly connected ISPs based on the source address. Which two statements are correct in this scenario? (Choose two.)

A. RIB groups are used to hide routes in the inet. 0 routing table. B. FBF uses the forwarding routing instance type. C. FBF uses the no-forwarding routing instance type. D. RIB groups are used to copy routes from the inet. 0 routing table.

Question 9

You want to prevent rogue BPDUs from lab devices reaching the internal through the Lab_Switch device.

Referring to the exhibit, what should be done to accomplish this task?

A. Configure the three lab ports under the protocols layer2-control bpdu-block hierarchy on the switch B. Configure the three lab ports as edge ports C. Configure an input filter on interface xe-0/2/0 to discard the RSTP packets D. Configure protocols rstp with the bpdu-block-on-edge parameter for interface xe-0/2/0

Correct Answer: A

Question 10

You are configuring an IS-IS IGP network and do not see the IS-IS adjacencies established. In this scenario, what are two reasons for this problem? (Choose two.)

A. The lo0 interface is not included as an IS-IS interface. B. MTU is not at least 1492 bytes. C. The Level 2 routers have mismatched areas. D. IP subnets are not a /30 address.

Question 11

A switch uses the factory-default storm control configuration. A sudden unknown-unicast burst causes packet loss for only 4-5 seconds before stabilizing. Which statement describes why normal operation resumes automatically?

A. Storm control triggers GRES recovery. B. Storm control shuts down the interface and re-enables it after 5 seconds. C. Storm control applies only to multicast traffic by default. D. Storm control drops only excess packets until traffic falls below the threshold.
