Q1. Refer to the exhibit.
If IEEE 802.1w is in use for this network design, what are two locations where spanning-tree root can be placed to ensure the least-disruptive Layer 2 failover for clients within VLANs 3 and 4? (Choose two.)
A. Switch A
B. Switch B
C. Switch C
D. Switch D
Q2. When creating a design plan for IPv6 integration, you decide to use stateless encapsulation of IPv6 packets into IPv4 tunnels between subscriber CPEs and a border relay. Which deployment technique allows for this functionality?
B. Dual-Stack Lite
Q3. When designing a large full mesh network running OSPF, how would you reduce LSA repetition?
A. Elect a DR and BDR.
B. Use access control lists to control outbound advertisements.
C. Choose one or two routers to re-flood LSA information.
D. Put each of the point-to-point links in your full mesh networking into a separate area.
Q4. A network designer is working with a company to improve convergence at the Layer 2 control plane and decides to use LACP. Which of these components does LACP use to create the system ID?
A. LACP system priority and switch MAC address
B. LACP port priority and switch MAC address
C. LACP port priority and port number
D. LACP system priority and port number
Q5. Refer to the exhibit.
This new OSPF network has four areas, but the hub-and-spoke area experiences frequent flapping. You must fix this design failure. Which two mechanisms can you use to isolate the data center area from the hub-and-spoke area without losing IP connectivity? (Choose two.)
A. Make the DC area totally stub.
B. Make the DC area an NSSA.
C. Convert the DC area to EIGRP protocol.
D. Deploy a prefix summarization on router D.
E. Use OSPF distribute-list filtering on router A.
Q6. A new video multicast application is deployed in the network. The application team wants to use the 18.104.22.168 multicast group to stream the video to users. They want to know if this choice will impact the existing multicast design. What impact will their choice have on the existing multicast design?
A. Because 22.214.171.124 is a private multicast range, a flood of PIM packets that have to be processed by the CPU and hosts will be sent by the routers in the network.
B. Because 126.96.36.199 is a private multicast range, the rendezvous point has to send out constant group updates that will have to be processed by the CPU and hosts.
C. The multicast application sends too many packets into the network and the network infrastructure drops packets.
D. The 188.8.131.52 group address maps to a system MAC address, and all multicast traffic will have to be sent to the CPU and flooded out all ports.
Q7. 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
Q8. A company is planning to connect its 30 sites with a VPLS WAN backbone. A router at each site should establish neighborships with all other routers using the OSPF routing protocol. Which three points must be considered regarding DR and BDR when different router platforms are used? (Choose three.)
A. It is a best practice that the routers with the most powerful hardware should take the role of the DR and BDR.
B. If the IP OSPF priority is the same for all routers, the highest loopback IP address and router ID will decide which routers will take the DR and BDR role during the selection process.
C. To select the DR and BDR, the IP OSPF priority must be set to a higher value than the default value at the DR and BDR during the selection process.
D. To select the DR and BDR, the IP OSPF priority must be set to a lower value than the default value at the DR and BDR during the selection process.
E. The role for the DR and BDR will be selected when a new OSPF router comes up.
F. To force two routers to become a DR and a BDR, the IP OSPF priority can be set to zero at all other OSPF routers.
Q9. 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.
Q10. Which two factors can significantly affect the OSPF network convergence time? (Choose two.)
A. the tuning of OSPF LSA timers
B. the number of OSPF routes
C. the diameter of the OSPF network
D. different processor capabilities of devices
