QUESTION 81

You are the lead network designer for an enterprise company called ABC, and you are leading design discussions regarding IPv6 implementation into their existing network. A question is raised regarding older Layer 2 switches that exist in the network, and if any changes are required to these Layer 2 switches for successful IPv6 implementation. Which two responses should you give? (Choose two.)

 

A.

IPv6 is transparent on Layer 2 switches, so there is no need to make any changes to the Layer 2 switches.

B.

If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ICMPv6 snooping at Layer 2 switches.

C.

If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support DHCPv6 snooping at Layer 2 switches.

D.

If IPv6 multicast deployment is planned, then make sure that Layer 2 switches support MLD snooping at Layer 2 switches.

E.

If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ND snooping at Layer 2 switches.

Correct Answer: C

 

 

 

 

 

QUESTION 84

Refer to the exhibit. This diagram depicts the design of a small network that will run EIGRP on R1 and R2, and EIGRP Stub on R3. In which two ways will this network be impacted if there is link instability between R1 and R2? (Choose two.)

 

clip_image002

 

A.

R1 will have routes in its routing table that originate from R2 and R3.

B.

R3 will have routes in its routing table that originate from R1 and R2.

C.

R2 will have routes in its routing table that originate from R1 and R3.

D.

R3 will be transit for traffic between R1 and R2.

E.

R3 will not be transit for traffic between R1 and R2.

 

Correct Answer: BE

 

 

QUESTION 85

Which restriction prevents a designer from using a GDOI-based VPN to secure traffic that traverses the Internet?

 

A.

Enterprise host IP addresses are typically not routable.

B.

GDOI is less secure than traditional IPsec.

C.

Network address translation functions interfere with tunnel header preservation.

D.

The use of public addresses is not supported with GDOI.

 

Correct Answer: C

 

 

 

 

 

 

 

 

 

QUESTION 86

Refer to the exhibit. Your company designed a network to allow server VLANs in a data center to span all access switches. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches. In which three ways should the design of the STP domain be optimized for server and application performance? (Choose three.)

 

clip_image004

 

A.

Use loop guard on access ports.

B.

Use PortFast on access ports.

C.

Use root guard on access ports.

D.

Align Layer 2 and Layer 3 forwarding paths.

E.

Use BPDU Skew Detection on access ports.

F.

Explicitly determine root and backup root bridges.

QUESTION 87

A company requests that you consult with them regarding the design of their production, development, and test environments. They indicate that the environments must communicate effectively, but they must be kept separate due to the inherent failures on the development network. What will be configured on the links between the networks to support their design requirements?

 

A.

IBGP

B.

EBGP

C.

OSPF

D.

static routes

 

Correct Answer: B

 

 

QUESTION 88

A data center provider has designed a network using these requirements:

 

clip_image006Two data center sites are connected to the public Internet.

clip_image006[1]Both data centers are connected to different Internet providers.

clip_image006[2]Both data centers are also directly connected with a private connection for the internal traffic, and public Internet traffic can also be routed at this direct connection.

clip_image006[3]The data center provider has only one /19 public IP address block.

 

Under normal conditions, Internet traffic should be routed directly to the data center where the services are located. When one Internet connection fails, the complete traffic for both data centers should be routed by using the remaining Internet connection. In which two ways can this routing be achieved? (Choose two.)

 

A.

The data center provider must have an additional public IP address block for this routing.

B.

One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP weight and the /20 block from the remote data center is sent out with a higher BGP weight at both sites.

C.

One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out without path prepending and the /20 block from the remote data center is sent out with path prepending at both sites.

D.

One /20 block is used for the first data center and the second /20 block is used for the second data center. Each /20 block is only sent out locally. The /19 block is sent out at both Internet connections for the backup case to reroute the traffic through the remaining Internet connection.

E.

One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP local preference and the /20 block from the remote data center is sent out with a higher BGP local preference at both sites.

F.

BGP will always load-balance the traffic to both data center sites.

 

Correct Answer: CD

 

 

QUESTION 89

When creating a network design that routes an IGP over L2VPNs, with which device does the remote CE router form an IGP adjacency?

 

A.

the hub site PE router

B.

the hub site CE router

C.

the directly connected PE router

D.

The IGP will not establish adjacency over the MPLS network.

 

Correct Answer: B

 

 

QUESTION 90

A network administrator is in charge of multiple IPsec VPN headend devices that service thousands of remote connectivity, point-to-point, IPsec/GRE tunnels. During a recent power outage, in which it was found that a backup power supply in one of those headend devices was faulty, one of the headend routers suffered a complete shutdown event. When the router was succ
essfully recovered, remote users found intermittent connectivity issues that went away after several hours. Network operations staff accessed the headend devices and found that the recently recovered unit was near 100% CPU for a long period of time. How would you redesign the network VPN headend devices to prevent this from happening again in the future?

 

A.

Move the tunnels more evenly across the headend devices.

B.

Implement Call Admission Control.

C.

Use the scheduler allocate command to curb CPU usage.

D.

Change the tunnels to DMVPN.

 

Correct Answer: B
