Question1: 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?

Question2: Click the Exhibit.

Referring to the exhibit, what is the correct OSPF interface state for the ge-0/0/1 interface?

Question3: What is required on the egress and ingress devices to transport IPv6 traffic across an IPv4 network?

Question4: Which statement is true about routing instances on Junos devices?

Question5: An IS-IS TLV includes which two attributes? (Choose two.)

Question6: You asked to deploy a large-scale IS-IS network with multiple areas.
In this scenario, which two statements are true? (Choose two.)

Question7: Click the Exhibit.


You are using OSPF as your IGP in your network. You have applied the OSPF configuration shown in the exhibit to router R1.
Which statement is true in this scenario?

Question8: You are configuring a default static route using the default preference value. You want to ensure that any static route that you configure in the future will be less preferred than the OSPF routes that are configured on the network.
Which command will accomplish this task?

Question9: A customer pays for the bandwidth on a per-packet basis. The network administrator wants to constrain costs and prevent Layer 2 loops on a multihomed Layer 2 WAN network.
Which technology would satisfy these requirements?

Question10: Click the Exhibit.

Your network consists of subnets shown in the exhibit. You are asked to create an aggregate route for Router 1.
What is the appropriate prefix for the aggregate route in this scenario?

Question11: Which statement is true about GRE encapsulation?

Question12: Click the Exhibit.

Referring to the exhibit, which two statements are true? (Choose two.)

Question13: Which statement is true regarding default MPLS label handling?

Question14: Click the Exhibit.

Referring to the configuration in the exhibit, which statement is true?

Question15: Click the Exhibit.


Referring to the exhibit, the GRE tunnel between R-1 and R2 allows connectivity between User-1 and Server-1. User-1 can communicate with Server-1 with packets that are up to 1448 bytes in size.
However, if the packet size is larger than 1448, User-1 cannot communicate with Server-1.
In this scenario, how do you solve the communication problem?

Question16: Which two statements correctly describe the BGP community attribute? (Choose two.)

Question17: Which two routing protocols make use of a designated router, or pseudo node, to represent a broadcast network? (Choose two.)

Question18: Click the Exhibit.

On an MX Series device, you must enable routing between VLANs 100,200, and the Internet ge-5/1/0, and ge-5/1/2 are bundled into interface ae3. Ge-5/1/4, and ge-5/1/5 are bundles into interface ae2. Both AE bundles trunk VLANs 100 and 200.
In this scenario, what is the correct configuration snippet for VLAN 100?

Question19: Click the exhibit.

A customer has two VLANs to extend between Site-1 and Site-2. The customer does not want to route the VLANs or renumber the VLANs.
Referring to the exhibit, which two VLAN IDs are egressing the MX Series device towards the optical transport network after translation? (Choose two.)

Question20: Click the exhibit.


Referring to the exhibit, which configuration must be set on R2 to from a Level 1 IS-IS adjacency with R1?

Question21: Click the Exhibit.

You are planning the addition of a new EX3400 Series device to the network (EX-3400-7) to service MSTI-
1 and MSTI-2.
Referring to the exhibit, which requirement must be met on EX-3400-7 for the MSTP instances to become fully operational and resilient?

Question22: Click the Exhibit.
Route Next-hop AS-Path Origin Local Preference
Route 1 ISP 1 123 88 65512 I 100
Route 2 ISP 2 678 651111 E 100
Route 3 ISP 3 3245 6532 1231 65510 ? 200
Route 4 ISP 4 65512 E 150
You are receiving the same route prefix from four EBGP neighbors.
Based on the information provided in the exhibit, which route will be selected?

Question23: What are two valid next-hop types that would be configured for a static route? (Choose two.)

Question24: Which two statements are true about NSR? (Choose two.)

Question25: Which two statements are correct regarding TLVs in IS-IS? (Choose two.)

Question26: Click the exhibit.

Customer 1 has experienced some hardware failures that erroneously transitioned some links into a forwarding state, as shown in the exhibit.
In this scenario, which STP feature set would solve this problem?

Question27: You are establishing RSVP LSPs through your MPLS-enabled network. You are asked to ensure that the LSPs will support end-to-end class-of-service handling.
Which statement is correct in this scenario?

Question28: Which two fields of a hello packet must match on both routers when forming an OSPF adjacency? (Choose two.)

Question29: Which statement is true when using VLANs in a bridge domain on an MX Series device?
