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.

Answer(s): B,D



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

Answer(s): A

Explanation:

-Synchronous replication ensures that the data on the secondary site is always up-to-date with the data on the primary site. This means that there is no RPO, as no data will be lost in the event of a failure.
-Geographically dispersed dual data centers means that the secondary site is located in a different geographical location from the primary site. This helps to protect against natural disasters and other events that could affect both sites.
-MPLS (Multiprotocol Label Switching) is a high-performance network technology that can be used to replicate data between geographically dispersed sites.
The other options are not as suitable for this scenario.

-Asynchronous replication does not guarantee that the data on the secondary site is always up-to-date with the data on the primary site. This means that there is an RPO, and some data could be lost in the event of a failure.
-Metro Ethernet is a less reliable network technology than MPLS. This means that it is more likely to experience outages, which could lead to data loss.
-CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing) are both optical networking technologies that can be used to transmit data over long distances. However, they are not as reliable as MPLS, and they can be more expensive.



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

Answer(s): C,E

Explanation:

Solutions is already created, nothing mentioned about new technologies (staff experience is out), I hope it's not year 2023 (no components issue). Cost and time to build the solution.

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

Answer(s): C

Explanation:

The Open Group Architecture Framework, or TOGAF, is intended to serve as a standard for developing and implementing very large computer systems. TOGAF is used by 80% of Global 50 companies today. TOGAF® is used to help organizations design an IT infrastructure that is adapted to meet their requirements.
