2V0-21.23 Question 143
Select 3An organization is planning to implement a disaster recovery (DR) solution for its primary data center. They intend to use VMware vSphere Replication to protect critical virtual machines (VMs). However, they have limited bandwidth between the primary and DR sites. Which of the following use cases would best align with this organization's requirements and constraints?
- A
Protecting VMs with low change rates to ensure data replication does not saturate the available bandwidth
- B
Implementing synchronous replication for zero data loss during a disaster
- C
Configuring Recovery Point Objectives (RPOs) to balance data protection and bandwidth usage
- D
Using vSphere Replication compression to optimize data transfer over limited bandwidth
- E
Replicating large database VMs with high change rates for maximum data protection
Show answer and explanation
Correct answers: A, C, D
Explanation
The organization is constrained by limited bandwidth, making it essential to prioritize use cases that minimize data transfer. Protecting VMs with low change rates reduces network usage, while configuring RPOs ensures a balance between data protection and bandwidth. Additionally, using vSphere Replication’s compression feature optimizes the available network capacity. Synchronous replication and replicating high-change-rate VMs are unsuitable due to the bandwidth requirements.
- A. Correct.
Protecting VMs with low change rates is a key use case for vSphere Replication in environments with limited bandwidth, as it minimizes the amount of data sent over the network.
- B. Incorrect.
Synchronous replication is not supported by vSphere Replication, which operates asynchronously. Additionally, it requires substantial bandwidth to achieve zero data loss, making it unsuitable for this scenario.
- C. Correct.
Configuring RPOs allows the organization to balance data protection needs with available bandwidth, making it a critical use case in environments with constraints.
- D. Correct.
vSphere Replication supports compression to optimize data transfer, which is particularly beneficial when bandwidth is limited.
- E. Incorrect.
Replicating large database VMs with high change rates would consume excessive bandwidth and is not an ideal use case for environments with limited network capacity.
