• Question 141:

  Refer to the exhibit.

  

  This enterprise customer wants to stream one-way video from their head office to eight branch offices using multicast. Their current service provider provides a Layer 3VPN solution and manages the CE routers, but they do not currently multicast. Which solution quickly allows this multicast traffic to go through while allowing for future scalability?

  A. Enable a GRE tunnel between nodes C1 and C4

  B. Enable a GRE tunnel between nodes CE1 and CE2

  C. Enable a GRE tunnel between nodes C2 and C4

  D. Implement hub and spoke MPLS VPN over DMVPN(also known as 2547oDMVPN) between CE1 and CE2

  E. The service provider must provide a Draft Rosen Solution to enable a GRE tunnel node PE1 and PE2

  Correct Answer: B

• Question 142:

  Refer to the exhibit.

  

  Transit traffic in this large enterprise campus network passes the eBGP core. Per security policy, traffic coming from AS 65444 destined for AS 65466 and vice-versa must pass through AS 65400. An audit discovers that traffic between 65444 and 65466 did not pass through 65400, instead it is communicating directly. How must you design BGP to ensure that the traffic from AS 65444 destined for AS 65466 passes through AS65400 on this broadcast network?

  A. Apply an ACL on AS 65466 to drop the direct traffic between AS 65444 and AS 65466

  B. Apply AS-path prepending on AS 65466 and AS 65444

  C. Apply next-hop self on both BGP neighbors on AS 65400

  D. Apply the MED attribute on the BGP session for AS 65444

  Correct Answer: C

• Question 143:

  How can EIGRP topologies be designed to converge as fast as possible in the event of a point-to-point link failure?

  A. Build neighbor adjacencies in a triangulated fashion

  B. Build neighbor adjacencies in a squared fashion

  C. Limit the query domain by use of distribute lists

  D. Limit the query domain b use of summarization

  E. Limit the query domain by use of default routes

  Correct Answer: D

• Question 144:

  Which three options are IS-IS design considerations when connecting two Layer 3 switches directly using a 10 GBASE-T cabling and formatting an IS-IS neighbor adjacency?

  A. The default IS-IS network type is point-to-point so a DIS is not elected

  B. A DIS is elected between the IS-IS neighbors and the elected DIS is pre-empted if router with a higher system ID is connected

  C. The area, levels, and interface MTU parameters must match, and system MTU must be unique for two IS-IS routers to become adjacent

  D. Faster IS-IS hello and dead timers increase bandwidth and CPU use, and may cause instability

  E. The IS-IS hello and dead timers should be tuned to detect failures as quickly as possible

  F. A DIS is elected between the IS-IS neighbors and the elected Dis is pre-empted if a router with a lower system ID is connected

  G. The hello and dead timers must match for two IS-IS routers to become adjacent

  Correct Answer: CDF

• Question 145:

  A company would like to distribute a virtual machine (VM) hosting cluster between three data centers with the capability to move VMs between sites. The connectivity between data centers is IP only and the new design should use the existing WAN. Which Layer 2 tunneling technology do you recommend?

  A. AToM

  B. L2TPv3

  C. OTV

  D. VPLS

  Correct Answer: C

• Question 146:

  At which two networks points is route summarization supported? (Choose two)

  A. At EIGRP AS boundaries

  B. At EIGRP interface boundaries

  C. At OSPF virtual-link boundaries

  D. At EIGRP are boundaries

  E. At OSPF area boundaries

  F. At EIGRP stub interface boundaries

  Correct Answer: BE

• Question 147:

  Which are two data plane hardening techniques? (Choose two)

  A. Infrastructure ACLs

  B. Control Plane Policing

  C. Redundant AAA servers

  D. Disable unused services

  E. Routing protocol authentication

  F. SNMPv3

  G. Warning banners

  Correct Answer: AB

• Question 148:

  Refer to the exhibit.

  

  This layer 2 network is expected to add 150 VLANS over the next year, In addition to the existing 50 VLANs within the network which STP types will support this design requirement the least amount of CPU resource and achieving load balancing?

  A. PVST+

  B. CST

  C. MST

  D. RSTP

  Correct Answer: C

• Question 149:

  What is a design benefit of PortFast?

  A. PortFast allows small, unmanaged switches to be plugged into ports of access switches without risking switch loops

  B. PortFast disables spanning-tree on the port, which puts the port into the forwarding state immediately after it is connected

  C. Portfast does not generate a spanning-tree topology change when a station on a port is connected or disconnected

  D. PortFast detects one-way communications on the physical port, when prevents switch loops

  E. PortFast prevents switched traffic from traversing suboptimal paths on the network

  F. PortFast prevents switch loops that are caused by a unidirectional point-to-point link condition on Rapid PVST+ and MST

  Correct Answer: B

• Question 150:

  You are implementing a one-to-many multicast solution for a large service provider network. Which technology offers optimal routing of multicast traffic?

  A. PIM sparse mode

  B. PIM SSM

  C. Anycast RP

  D. MSDP

  E. Bidirectional PIM.

  Correct Answer: B
