Which two statements explain the operation of BFD asynchronous mode? (Choose two.)

  1. BFD asynchronous mode with echo packets uses separate control packets and echo packets
  2. BFD asynchronous mode with and without echo packets use control packets
  3. BFD asynchronous mode with echo packets combines the control packets and echo packets into a single packet
  4. BFD asynchronous without echo packets has control packets sent back to the originating router, which echoes the control packet to detect failures
  5. BFD asynchronous mode without echo packets uses control packets, and BFD asynchronous mode with echo packets does not

Answer(s): A,B



Various teams in different organizations within an enterprise are preparing low-level design documents to capture network parameters using a Waterfall project model:

•hardware sizing and power consumption
•Layer 2 and layer 3 services parameters
•configuration of all control plane protocols

Input from relevant stakeholders was captured at the start of the project, and the project scope has been defined based on the parameters above. What impact will it have on documentation and project deliverables if the stakeholders ask to have changes earned out in the network before the information has been captured?

  1. Significant effort and time are required
  2. Rework is expected before the delivery
  3. This provides more opportunity to think outside the box
  4. This provides a flexible approach to incorporate changes

Answer(s): B



Which two benefits can software defined networks provide to businesses? (Choose two.)

  1. provides additional redundancy
  2. decentralized management
  3. reduced latency
  4. enables innovation
  5. reduction of OpEx/CapEx
  6. meets high traffic demands

Answer(s): C,E

Explanation:

-C. Reduced latency: SDN can reduce latency by centralizing the control of the network and by making it easier to optimize traffic flows.
-E. Reduction of OpEx/CapEx: SDN can reduce OpEx/CapEx by making it easier to manage and maintain the network, and by enabling the use of less expensive hardware.

The other options are also benefits of SDN, but they are not as significant as the two listed above.

-Provides additional redundancy: SDN can provide additional redundancy by allowing the network to be divided into multiple zones, each of which can be managed independently.
-Decentralized management: SDN can allow for decentralized management by making it possible to delegate control of the network to different teams or departments.
-Enables innovation: SDN can enable innovation by making it easier to deploy new network services and applications.
-F. Meets high traffic demands: SDN can meet high traffic demands by making it easier to scale the network and by providing more granular control over traffic flows.



Company XYZ is migrating their existing network to IPv6 and they must plan for Layer 2 and Layer 3 devices. Some of the access layer switches do not support IPv6, however, core and distribution switches fully support unicast and multicast routing. The company wants to minimize cost of the migration. Which migration strategy should be used in the design?

  1. The access layer switches must support IGMP snooping at a minimum. Any switches that do not support IGM snooping must be replaced.
  2. The access layer switches must support DHCPv6. Any switches that do not support DHCPv6 must be replaced.
  3. Upgrade the nonsupporting switches. Otherwise, it will cause an issue with the migration.
  4. Layer 2 switches will not affect the implementation of IPv6. They can be included in the design in their current state.

Answer(s): C

Explanation:

As layer 2 switches can potentially impact the implementation of IPv6, particularly if they do not support features such as Neighbor Discovery Protocol (NDP) and Stateless Address Autoconfiguration (SLAAC).
