Cisco 400-007 Online Questions & Answers

• Question 141:

  Company XYZ is planning to deploy primary and secondary (disaster recovery) data center sites. Each of these sites will have redundant SAN fabrics and data protection is expected between the data center sites. The sites are 100 miles (160 km) apart and target RPO/RTO are 3 hrs and 24 hrs, respectively.

  Which two considerations must Company XYZ bear in mind when deploying replication in their scenario? (Choose two.)

  A. Target RPO/RTO requirements cannot be met due to the one-way delay introduced by the distance between sites.
  B. VSANs must be routed between sites to isolate fault domains and increase overall availability.
  C. Synchronous data replication must be used to meet the business requirements
  D. Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.
  E. VSANs must be extended from the primary to the secondary site to improve performance and availability.
  B. VSANs must be routed between sites to isolate fault domains and increase overall availability.
  D. Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.

  D. BIDIR-PIM
  B. PIM-SM

• Question 146:

  Which two impacts of adding the IP event dampening feature to a network design are true? (Choose two.)

  A. It protects against routing loops.
  B. It switches traffic immediately after a link failure.
  C. lt speeds up link failure detection.
  D. It reduces the utilization of system processing resources.
  E. It improves overall network stability.
  D. It reduces the utilization of system processing resources.
  E. It improves overall network stability.

• Question 147:

  Company XYZ wants to deploy OSPF. The design plan requires that two OSPF networks be mutually redistributed at multiple locations and ensure end-to-end connectivity to all of the company's networks. Which technology can be used to fulfill the requirements while avoiding the creation of routing loops?

  A. Create a virtual link between ASBRs.
  B. Change the router ID for both ASBRs.
  C. Redistribute routes as external type 2 routes.
  D. Use route maps on ASBRs to filter routes with tags so they are not redistributed.
  D. Use route maps on ASBRs to filter routes with tags so they are not redistributed.

• Question 150:

  An MPLS service provider is offering a standard EoMPLS-based VPLS service to Customer A. providing Layer 2 connectivity between a central site and approximately 100 remote sites. Customer A wants to use the VPLS network to carry its internal multicast video feeds which are sourced at the central site and consist of 20 groups at Mbps each. Which service provider recommendation offers the most scalability?

  A. EoMPLS-based VPLS can carry multicast traffic in a scalable manner
  B. Use a mesh of GRE tunnels to carry the streams between sites
  C. Enable snooping mechanisms on the provider PE routers.
  D. Replace VPLS with a Layer 3 MVPN solution to carry the streams between sites
  D. Replace VPLS with a Layer 3 MVPN solution to carry the streams between sites
