Question 445 of 499
Operations and SupporthardMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to switch to asynchronous replication and accept a longer RPO, or choose a DR region with lower network latency. This is because synchronous replication requires the primary database to wait for an acknowledgment from the secondary replica before committing each transaction; with 40 milliseconds of network latency between regions 500 miles apart, the commit time far exceeds the 5-second RPO threshold, causing transaction timeouts and the loss of the last three minutes of data. On the CompTIA Cloud+ CV0-004 exam, this scenario tests your understanding that synchronous replication is not a guarantee of zero data loss when latency is high—a common trap is assuming synchronous always means perfect consistency. The key insight is that disaster recovery data loss occurs when synchronous replication latency forces the primary to drop unacknowledged writes. Remember the mnemonic: “Sync needs speed; async accepts the deed”—if latency is high, switch to async or move the replica closer.

CV0-004 Operations and Support Practice Question

This CV0-004 practice question tests your understanding of operations and support. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A financial services company has a disaster recovery (DR) plan for its cloud infrastructure that includes a secondary region 500 miles away. The plan uses synchronous replication for the primary database. During a scheduled DR test, the administrator triggers a failover to the secondary region. The application comes up, but the database is missing the last three minutes of transactions. The RPO requirement is 5 seconds. The administrator finds that the network latency between regions is 40 milliseconds. What is the most likely cause of the data loss, and what should the administrator do?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "most likely"

    Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

  • Clue: "primary"

    Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Switch to asynchronous replication and accept a longer RPO, or choose a DR region with lower network latency.

Synchronous replication with 40ms latency exceeds the typical threshold for zero data loss because the transaction commit must wait for acknowledgment from the replica, leading to timeouts and potential data loss. The correct action is to switch to asynchronous replication with a realistic RPO or move to a region with lower latency. Option B directly addresses the root cause.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

  • Switch to asynchronous replication and accept a longer RPO, or choose a DR region with lower network latency.

    Why this is correct

    Synchronous replication over long distances with high latency is prone to timeouts; asynchronous replication or a closer region is needed.

    Clue confirmation

    The clue words "most likely", "primary" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Reduce the RPO requirement to 30 seconds.

    Why it's wrong here

    Changing the RPO requirement may not solve the technical limitation; the replication method must also change.

  • Enable compression on the replication link to reduce data transfer time.

    Why it's wrong here

    Compression can help but does not overcome the fundamental latency issue in synchronous replication.

  • Increase the instance size in the secondary region to handle more transactions.

    Why it's wrong here

    Instance size does not affect replication consistency; the issue is latency.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
