CV0-004 Practice Question: Which THREE of the following are common causes of…
Which THREE of the following are common causes of application performance degradation in a cloud environment? (Choose three.)
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
✓
Network latency and bandwidth limitations
Options B, C, and D are correct. Network latency and bandwidth limitations (B) slow data transfer, directly degrading performance. Poorly optimized application code (C) causes inefficiencies like excessive resource consumption or blocking operations. Resource exhaustion (D) — including CPU, memory, or disk I/O — throttles application throughput. Option A is incorrect because insufficient security groups affect traffic rules but not performance; they may block or allow traffic but don't degrade speed. Option E is incorrect because overprovisioned storage means excess capacity, which does not degrade performance; underprovisioned storage would cause issues.
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.
- ✓
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.
