Question 51

Report Export Collapse

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.)

Target RPO/RTO requirements cannot be met due to the one-way delay introduced by the distance between sites.

Target RPO/RTO requirements cannot be met due to the one-way delay introduced by the distance between sites.

VSANs must be routed between sites to isolate fault domains and increase overall availability.

Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.

Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.

VSANs must be extended from the primary to the secondary site to improve performance and availability.

VSANs must be extended from the primary to the secondary site to improve performance and availability.

Suggested answer: C, D
Explanation:

synchronous data replication must be used to meet the business requirements, is incorrect. As described above, asynchronous replication would be a better choice in this scenario due to the distance between the data center sites and the target RPO/RTO requirements. asynchronous data replication should be used in this scenario to avoid performance impact in the primary site, is correct. Asynchronous replication would allow Company XYZ to meet the target RPO/RTO requirements while avoiding the performance impact of synchronous replication

Question 57

Report Export Collapse

Company XYZ is in the process of identifying which transport mechanism(s) to use as their WAN technology. Their main two requirements are.

• a technology that could offer DPI, SLA, secure tunnels, privacy, QoS, scalability, reliability, and ease of management

• a technology that is cost-effective

Which WAN technology(ies) should be included in the design of company XYZ?

Software-defined WAN should be the preferred choice because it complements both technologies, covers all the required features, and it is the most cost-effective solution.

Internet should be the preferred option because it is cost effective and supports BFD, IP SLA. and IPsec for secure transport over the public Internet.

Internet should be the preferred option because it is cost effective and supports BFD, IP SLA. and IPsec for secure transport over the public Internet.

Both technologies should be used. Each should be used to back up the other one; where the primary links are MPLS, the internet should be used as a backup link with IPsec (and vice versa).

You were tasked to enhance the security of a network with these characteristics: • A pool of servers is accessed by numerous data centers and remote sites • The servers are accessed via a cluster of firewalls • The firewalls are configured properly and are not dropping traffic • The firewalls occasionally cause asymmetric routing of traffic within the server data center. Which technology should you recommend to enhance security by limiting traffic that could originate from a hacker compromising a workstation and redirecting flows at the servers?
