Review 349 400-007 practice questions with answer explanations and community insights.

Question 1

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.)

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

Question 2

An architect receives a business requirement from a CTO that states the RTO and RPO for a new system should be as close as possible to zero. Which replication method and data center technology should be used?

  1. synchronous replication over geographically dispersed dual data centers via MPLS
  2. synchronous replication over dual data centers via Metro Ethernet
  3. asynchronous replication over geographically dispersed dual data centers via CWDM
  4. asynchronous replication over dual data centers via DWDM

Question 3

What are two primary design constraints when a robust infrastructure solution is created? (Choose two.)

  1. component availability
  2. monitoring capabilities
  3. project time frame
  4. staff experience
  5. total cost

Question 4

Which network management framework can be used to develop a network architecture that contains business requirements analysis, gap analysis, and network diagrams as artifacts to be used for design and implementation later?

  1. FCAPS
  2. Cobit
  3. TOGAF
  4. ITIL

Question 5

Which two types of planning approaches are used to develop business-driven network designs and to facilitate the design decisions? (Choose two.)

  1. strategic planning approach
  2. business optimization approach
  3. tactical planning approach
  4. modular approach
  5. cost optimization approach
