Question3: Click the Exhibit button. You have two routers connected over a Gigabit Ethernet link as shown in the exhibit It is required that an IS-IS adjacency be established without the need for a designated intermediate system (DIS)

Which configuration statement entered on both routers will achieve this goal?

Question4: An IS-IS TLV includes which two attributes? (Choose two.)

Question5: You are setting up a new IS-IS adjacency between two devices. The new Level1 adjacency is not establishing.

Question8: Click the Exhibit.

The router with the configuration shown in the exhibit has two interfaces, both of which are operational and can pass traffic. These interfaces are connected to two different routers, both of which are configured for OSPF area 0.0.0.1. The router has received LSAs and can now send traffic into the backbone area.
Which two statements are correct? (Choose two.)

Question9: Which Layer 2 mechanism logically groups network nodes into separate broadcast domains?

Question10: Which two statements are correct regarding TLVs in IS-IS? (Choose two.)

Question11: 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?

Question12: What is the OSPFv3 router ID?

Question13: An IS-IS level 1-only router is configured within a larger multilevel hierarchy. Which OSPF area type resembles the routing information in the L1 router's table?

Question14: Which two configuration elements must match on all switches participating in the same MSTP region? (Choose two.)

Question15: Which three statements are true about the BGP community attribute? (Choose three.)

Question16: Which packet type does the router use to request up-to-date link-state information?

Question17: Click the Exhibit.

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

Question18: Click the Exhibit button. In the exhibit, all routers are sending routes to Router B.Which routes will be advertised from Router B to Router E?

Question19: What are two characteristics of a traditional Ethernet LAN? (Choose two.)

Question20: Click the Exhibit button. The policy shown in the exhibit has been configured and installed on your router.

What is the result of applying this policy?

Question21: Click the Exhibit button. Which two topologies shown in the exhibit could be implemented without a spanning-tree protocol? (Choose two.)

Question22: You have a stub OSPF area running in your network. Your supervisor has asked you to build a virtual link across this area to connect new equipment acquired in a recent ISP acquisition.Which statement is correct about this scenario?

Question23: 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?

Question24: Which configuration can be applied to ensure that no more than 600 MAC addresses are learned by a virtual switch?

Question25: Click the Exhibit button. In the exhibit, all routers are sending routes to Router B

Which routes will be advertised from Router B to Router D?

Question26: You have been asked to identify what the contributing routes are for route 204.7.15/21.Which command will show this information?

Question27: Which two fields of a hello packet must match on both routers when forming an OSPF adjacency? (Choose two.)

Question28: Which statement is true regarding default MPLS label handling?

Question29: Which two statements are correct regarding VPLS mesh groups? (Choose two.)

Question30: Which two IS-IS packet types are used to maintain IS-IS database synchronization? (Choose two.)

Question31: Click the Exhibit button. In the exhibit, three IPv6 addresses are listed. Which two statements are true? (Choose two.)

Question32: You are asked to configure and apply a new routing policy to influence routing advertisements received from a specific EBGP peer.
In this scenario, which statement is true?

Question33: 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?

Question34: 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?

Question35: You have just configured IPv6 in your network. A packet arrives on your router that exceeds the MTU size. How will an IPv6 router respond?

Question36: You are logged into a PE router participating in a Layer 3 VPN as defined in RFC 4364. You would like to ping the remotely connected CE router's loopback address. The address of the loopback is
122.161.2.1, the VPN routing-instance is called VPN-C.Which command will accomplish this goal?

Question37: Which two statements correctly describe the BGP community attribute? (Choose two.)
