Q93. Users are complaining of intermittent high packet loss for seconds at a time. The engineer troubleshooting the issue finds that a TenGigE link is bouncing for milliseconds at a time, causing the traffic path to reconverge onto a congested FastEthernet link. What can the engineer do to prevent this service-affecting reconvergence only in the case of momentary link bounces until the link can be repaired? 

A. decrease the carrier-delay up on both sides of the link 

B. disable keepalives and BFD 

C. decrease the carrier-delay down on both sides of the link 

D. increase the carrier-delay up on both sides of the link 

E. increase the carrier-delay down on both sides of the link 

Answer: D 


Q94. A network engineer wants to decrease the convergence time of a network that is running integrated IS-IS as an IGP, at the expense of bandwidth and CPU usage. Which two configuration tasks achieve this goal? (Choose two.) 

A. Configure the hold time to be 1 second. 

B. Configure the hello interval to be minimal. 

C. Ensure that hello-padding is disabled. 

D. Ensure that the hello multiplier is set to 3. 

E. Configure the hello multiplier to be 3. 

Answer: B,D

Q95. In a secure domain router scenario, which two functions are shared amongst all SDR in the system? (Choose two.) 

A. configuration 

B. protocols 

C. routing tables 

D. chassis-control 

E. switch-fabric 

Answer: D,E 

Explanation: 

Secure domain routers (SDRs) provide a means of partitioning a router into multiple, independent routers. SDRs perform routing functions in the same manner as a physical router but share resources with the rest of the system. For example, the applications, configurations, protocols, and routing tables assigned to an SDR belong to that SDR only, but other functions such as chassis control, switch fabric, and partitioning are shared with the rest of the system.

Q96. Refer to the exhibit. The configuration in the exhibit redistributes static route 172.16.0.0/24 into BGP. Which action does the route-map STATIC-TO-BGP do? 

A. Route 172.16.0.0/24 cannot be sent to the Internet. 

B. Route 172.16.0.0/24 cannot be re-advertised beyond its neighbors. 

C. Route 172.16.0.0/24 cannot be advertised outside of AS 100. 

D. Route 172.16.0.0/24 cannot be exported from BGP to another protocol. 

Answer: C 


Q97. Refer to the exhibit . 

A network engineer is troubleshooting a packet over SONET connection between Router A and Router B. What is causing the line protocol to be down? 

A. The keepalive must be set on both sides 

B. The POS CRC must be set on both sides. 

C. There is an encapsulation mismatch 

D. There is an MTU mismatch. 

Answer: C 


Q98. How many bits are expressed by";:" in the address 2D01:DB::C:B7BA:130B? 

A. 16 bits 

B. 32 bits 

C. 40 bits 

D. 44 bits 

E. 48 bits 

F. 52 bits 

G. 56 bits 

H. 64 bits 

Answer: E

Without a requirement to create VRF, which method is preferred to support IPv6 traffic between these sites? 

A. 6VPE 

B. H-VPLS 

C. L2TPv3 

D. VPLS 

E. 6CE 

F. 6PE 

Answer: F

Q100. Refer to the exhibit. 

An ISP engineer has been asked to identity a method to protect the PE and to control the number of BGP prefixes learned from his customers. The BGP session should be dropped if the PE router receives more than 1000 BGP prefixes. A syslog message should be generated when the number of BGP prefixes learned from CE exceeds 850. 

Which Cisco IOS command should the engineer apply on PE routers? 

A. neighbor 10.1.1.2 maximum-prefix 1000 85 

B. neighbor 10.1.1.2 maximum-prefix 1000 850 

C. neighbor 10.1.1.2 maximum-prefix 1000 85 warning-only 

D. neighbor 10.1.1.2 maximum-prefix 1000 850 warning-only
