CISA Practice Question: Given this configuration, which is the PRIMARY…

Exhibit

Refer to the exhibit.
recovery_time_objective = 2 hours;
recovery_point_objective = 15 minutes;
replication_type = synchronous;
bandwidth = 100 Mbps;
data change rate = 50 GB per hour;

Given this configuration, which is the PRIMARY concern?

⚠ Common exam trap

The trap here is that candidates often focus on the immediate performance impact (Option C) or the obvious bandwidth mismatch (Option A), but fail to recognize that the ultimate business requirement is the RPO, and insufficient bandwidth directly makes that requirement unachievable.

Correct answer & explanation

✓

Bandwidth may be insufficient to meet RPO

The primary concern is that bandwidth may be insufficient to meet the Recovery Point Objective (RPO). In synchronous replication, every write must be acknowledged by the remote site before the local write completes, so the link bandwidth must be at least equal to the peak data change rate. If bandwidth is lower, replication cannot keep up, causing the RPO (maximum acceptable data loss) to be violated as the backlog grows. This directly threatens the organization's ability to recover data within the defined time window.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Data change rate exceeds bandwidth
Why it's wrong here
This is essentially the same as A, but A correctly frames it in terms of RPO.
✗
RTO may not be achievable
Why it's wrong here
RTO depends on recovery speed, not directly on replication bandwidth.
✗
Synchronous replication may impact application performance
Why it's wrong here
Performance impact is possible but not the primary concern given the bandwidth mismatch.
✓
Bandwidth may be insufficient to meet RPO
Why this is correct
The required replication bandwidth exceeds available bandwidth, risking RPO violations.
