Cost And Performance Optimization practice questions
Use this page to practise SOA-C02 Cost And Performance Optimization practice questions. The goal is not to memorise dumps, but to understand the concept, review the explanation and improve your exam readiness.
What the exam tests
What to know about Cost And Performance Optimization
QoS questions usually test traffic classification (DSCP/CoS), queuing strategies, policing vs shaping and where each mechanism is applied.
DSCP and CoS marking and trust boundaries.
Queuing mechanisms: FIFO, WFQ, CBWFQ, LLQ.
Policing (drops excess) vs shaping (delays excess).
Where QoS is applied: ingress, egress, LAN, WAN.

Question 2hardmultiple choice
Full question →A company runs a web application on Amazon EC2 instances in an Auto Scaling group. The application uses Amazon EBS volumes (gp2) for data storage. The SysOps administrator notices that the storage costs are high, and the application's IOPS requirements are consistently below 3000. The administrator wants to reduce storage costs without affecting performance. Which action should the administrator take?
Question 3mediummultiple choice
Full question →A SysOps administrator manages a fleet of Amazon EC2 instances. The administrator needs to identify underutilized instances and receive recommendations for instance type changes to reduce costs. Which AWS service should be used to provide these rightsizing recommendations?
Question 4easymultiple choice
Full question →A SysOps administrator needs to ensure that all Amazon S3 buckets in an AWS account are configured with server-side encryption using AWS KMS (SSE-KMS). The administrator wants to automatically detect any S3 buckets that are not compliant and remediate them by enabling SSE-KMS. Which AWS service should be used to implement this automated compliance enforcement?
Question 5easymultiple choice
Full question →A SysOps administrator wants to identify Amazon EC2 instances that are underutilized to reduce costs. The administrator needs recommendations for rightsizing instances based on historical CPU and memory usage. Which AWS service provides these recommendations?
Watch out for
Common Cost And Performance Optimization exam traps
- ▸Policing drops traffic; shaping buffers it — they solve different problems.
- ▸DSCP EF (46) is for voice; AF classes are for data tiers.
- ▸QoS must be configured end-to-end to be effective.
- ▸CoS values are Layer 2; DSCP is Layer 3.

Frequently asked questions
- What does the SOA-C02 exam test about Cost And Performance Optimization?
- QoS questions usually test traffic classification (DSCP/CoS), queuing strategies, policing vs shaping and where each mechanism is applied.
- How should I use these practice questions?
- Select your answer before revealing the explanation. Then read why each option is right or wrong — this active recall approach builds retention far faster than re-reading notes.
- Can I practise just Cost And Performance Optimization questions in a focused session?
- Yes — the session launcher on this page draws every question from the Cost And Performance Optimization domain. Use a 10-question session first to gauge your baseline, then move to 20 or 30 once the weak spots are clear.
- Where can I practise other SOA-C02 topics?
- Use the topic links above to move to related areas, or go back to the SOA-C02 question bank to see all topics.
- Are these real exam questions or dumps?
- These are original practice questions written to test the same concepts the SOA-C02 exam covers. They are not copied from any real exam or dump site.
