Q1. Refer to the exhibit.
A customer runs OSPF with Area 5 between its aggregation router and an internal router. When a network change occurs in the backbone, Area 5 starts having connectivity issues due to the SPF algorithm recalculating an abnormal number of times in Area 5. You are tasked to redesign this network to increase resiliency on the customer network with the caveat that Router B does not support the stub area. How can you accomplish this task?
A. Set Area 5 to stubby at the ABR anyway.
B. Increase the bandwidth on the connection between Router A and Router B.
C. Turn on LSA throttling on all devices in Area 5.
D. Implement LSA filtering on the ABR, allowing summary routes and preventing more specific routes into Area 5.
E. Create a virtual link to Area 0 from Router B to the ABR.
Answer: D
Q2. When network summaries are created for access networks in a network design, how does it change the behavior of the Shortest Path First (SPF) running in a backbone area?
A. There would be fewer incremental SPFs.
B. There would be fewer partial SPFs.
C. There would be fewer full SPFs.
D. There would be no change with the SPFs.
Answer: B
Q3. Which three reasons to deploy an IDS sensor in promiscuous mode when you design a security solution are true? (Choose three.)
A. Solution should be resistant to sensor failure.
B. Solution should allow for stream normalization.
C. Solution should not impact jitter and latency for voice traffic.
D. Solution should allow for signature-based pattern matching.
E. Solution should allow to deny packets inline.
Answer: ACD
Q4. What is a key design aspect to be considered when designing an IP network that will be carrying real-time VoIP traffic?
A. Minimizing total bidirectional end-to-end delay to 0-150 ms
B. Minimizing total unidirectional end-to-end delay to 150-500 ms
C. Minimizing total bidirectional end-to-end delay to 0-50 ms
D. Minimizing total unidirectional end-to-end delay to 0-150 ms
Answer: D
Q5. For a storage area network design, which technology allows a switch to support multiple Fibre Channel IDs per fabric port?
A. N-Port Identifier Virtualization
B. Inter-Virtual Storage Area Network Routing
C. Zoning

F. Expansion Port Trunking
Answer: A
Q6. A junior engineer is implementing one of your optical designs and asks about CWDM (Coarse Wavelength Division Multiplexing). Which two features describe CWDM? (Choose two.)
A. typically used over long distances, but requires optical amplification
B. allows up to 32 optical carriers to be multiplexed onto a single fiber
C. shares the same transmission window as DWDM
D. uses the 850-nm band
E. Passive CWDM devices require no electrical power.
Answer: CE
Q7. You are designing the QoS features for a large enterprise network that includes DMVPN. When would you need to configure QoS preclassify?
A. when you are marking packets with the DSCP bits
B. when you are marking packets with the TOS bits
C. when your service provider requires the DSCP bits be set
D. when the QoS policy cannot be based on DSCP ToS bits
Answer: D
Q8. What are two functions of an NSSA in an OSPF network design? (Choose two.)
A. It overcomes issues with suboptimal routing when there are multiple exit points from the area.
B. It allows ASBRs to inject external routing information into the area.
C. An ASBR advertises Type 7 LSAs into the area.
D. An ABR advertises Type 7 LSAs into the area.
E. It uses opaque LSAs.
Answer: BC
Q9. Refer to the exhibit.
You must ensure that both core A and core B devices have only the minimum information required for reaching the spoke routers yet maintain full reachability during network failures.
Which of the following design solutions accomplishes these requirements?
A. Route summarization, with specific route leaking on hubs A and B
B. Route summarization, with GRE tunnel on hubs A and B
C. Implement PfR enhancements on hubs A and B.
D. Implement ODR for hub-to-spoke routing.
Answer: B
Q10. Refer to the exhibit.
In this BGP design, what is the next hop for 10.1.1.0/24 on R8 and R7?
A. The next hop for 10.1.1.0/24 on R7 is R8 and the next hop for R8 is R7.
B. The next hop for 10.1.1.0/24 on R7 is R5 and the next hop for R8 is R6.
C. The next hop for 10.1.1.0/24 on R7 is R6 and the next hop for R8 is R5.
D. The next hop for 10.1.1.0/24 on R7 is R3 and the next hop for R8 is R4.
Answer: A
