Question No: 81 – (Topic 1)

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.)

  1. It is a best practice that the routers with the most powerful hardware should take the role of the DR and BDR.

  2. 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.

  3. 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.

  4. 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.

  5. The role for the DR and BDR will be selected when a new OSPF router comes up.

  6. 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.

Answer: A,B,F

You are developing a migration plan to enable IPv6 in your IPv4 network. Starting at R3 and assuming default IS-IS operations, what is likely to happen when you enable IPv6 routing on the link from R3 to R2?

  1. Only R3 and R2 have IPv4 and IPv6 reachability.

  2. R2 receives an IPv6 default route from R3.

  3. Loopback reachability between all routers for IPv4 is lost.

  4. All routers except R2 are reachable through IPv4.

  5. R3 advertises the link from R3-R2 to R1, R4 and R5 only.

Answer: C

Question No: 83 – (Topic 1)

When designing a large full mesh network running OSPF, how would you reduce LSA repetition?

  1. Elect a DR and BDR.

  2. Use access control lists to control outbound advertisements.

  3. Choose one or two routers to re-flood LSA information.

  4. Put each of the point-to-point links in your full mesh networking into a separate area.

Answer: C

Question No: 84 – (Topic 1)

In which two ways is IPv4 and IPv6 traffic handled in a network design that uses QoS deployment options? (Choose two.)

  1. IPv6 and IPv4 traffic is treated in the same way by using a single QoS policy that classifies and matches on both protocols.

  2. IPv6 traffic is treated differently than IPv4 by using the flow-label field, which is built into the IPv6 packet header.

  3. IPv6 traffic does not require QoS because it uses to the flow-label field, which classifies and matches on the IPv6 protocol.

  4. IPv6 traffic is treated differently than IPv4 by using two different QoS policies.

  5. IPv6 traffic is treated differently than IPv4 because it uses only the DSCP value and not the IP precedence.

Answer: A,D

Question No: 85 – (Topic 1)

Company X will be integrating an IPv6 application into their network and wants to develop a test environment to evaluate application performance across the network. This application will require both unicast and multicast communications. The company can do this implementation only in certain areas of its existing IPv4-only network, but wants all areas to communicate with each other. When developing the design to provide connectivity between these testing locations, what tunneling technology would work in this scenario?

  1. ISATAP

  2. 6to4

  3. DMVPN

  4. 6vPE

  5. 6PE

Answer: C

Question No: 86 – (Topic 1)

In which two ways is a network design improved by the inclusion of IP Event Dampening? (Choose two.)

  1. reduces processing load

  2. provides sub-second convergence

  3. improves network stability

  4. prevents routing loops

  5. quickly detects network failures

Answer: A,C

Question No: 87 – (Topic 1)

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?

  1. IBGP

  2. EBGP

  3. OSPF

  4. static routes

Answer: B

Question No: 88 – (Topic 1)

A company plans to use BFD between its routers to detect a connectivity problem inside the switched network. An IPS is transparently installed between the switches. Which packets should the IPS forward for BFD to work under all circumstances?

  1. IP packets with broadcast IP source addresses

  2. IP packets with identical source and destination IP addresses

  3. fragmented packets with the do-not-fragment bit set

  4. IP packets with the multicast IP source address

  5. IP packets with the multicast IP destination address

  6. IP packets with the destination IP address 0.0.0.0

Answer: B

Question No: 89 – (Topic 1)

Voice traffic between two campus enterprise networks is growing. The network designers decide to add a second 10-Mb Metro Ethernet service parallel to their original 10-Mb service in order to provide more bandwidth and diversity. The QoS profile will be the same on the new 10-Mb service due to the voice stability on the first Metro Ethernet link. When the second link is added to the OSPF domain, which traffic design consideration would have the most impact on the voice traffic when both links are active?

  1. per-destination IP address basis

  2. per-flow basis

  3. per-packet basis

  4. per-source IP address basis

Answer: C

Question No: 90 – (Topic 1)

A network designer wants to improve a company network design due to multiple network crashes. Which technology would allow for the restore of a network connection without informing the Layer 3 protocol?

  1. Bidirectional Forwarding Detection

  2. automatic protection switching

  3. UniDirectional Link Detection

  4. Ethernet OAM
