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.
Which THREE of the following are common causes of application performance degradation in a cloud environment? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Network latency and bandwidth limitations
Options A, B, and C are correct. Resource exhaustion (CPU, memory, disk I/O) directly impacts performance. Network latency and bandwidth limitations slow down data transfer. Poorly optimized application code can cause inefficiencies. Option D is wrong because insufficient security groups do not affect performance; they affect traffic flow rules. Option E is wrong because overprovisioned storage means excess capacity, which does not degrade performance; underprovisioned storage would.
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.
✗
Insufficient number of security groups
Why it's wrong here
Security groups are for access control, not performance. Insufficient groups might lead to security issues, not degradation.
✓
Network latency and bandwidth limitations
Why this is correct
High latency or low bandwidth can cause delays in data transmission.

Read the scenario before looking for a memorised answer.
✓
Application code that is poorly optimized
Why this is correct
Inefficient code consumes more resources and degrades performance.

✓
Resource exhaustion (CPU, memory, disk I/O)
Why this is correct
Contention for resources leads to slowdowns and increased latency.

✗
Overprovisioned storage
Why it's wrong here
Overprovisioned storage provides more capacity than needed, which does not degrade performance; it may increase cost.
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.
What to study next
Got this wrong? Here's your next step.
Identify which CV0-004 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
