High Availability practice questions
Use this page to practise SAA-C03 High Availability 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 High Availability
High Availability questions test whether you can apply the concept in context, not just recognise a definition.
How the topic appears in realistic exam-style scenarios.
Which detail in the question changes the correct answer.
How to eliminate plausible but wrong options.
How to connect the question back to the wider exam objective.

Question 2mediummultiple choice
Full question →A claims workflow uses an RDS MySQL database and must remain available during an Availability Zone failure with minimal application changes. What should the architect enable? The design must avoid adding custom operational scripts.
Question 3mediummultiple choice
Full question →A claims workflow uses an RDS MySQL database and must remain available during an Availability Zone failure with minimal application changes. What should the architect enable? The architecture review board prefers a managed AWS-native control.
Question 4mediummultiple choice
Full question →A claims workflow uses an RDS MySQL database and must remain available during an Availability Zone failure with minimal application changes. What should the architect enable? The team wants the control to be enforceable during normal operations.
Question 5mediummultiple choice

Question 9easymultiple choice
Full question →A company runs Amazon RDS for MySQL in a Multi-AZ configuration. If the primary database instance fails, what is the expected behavior?
Question 10easymultiple choice
Full question →A company needs an Amazon RDS database that automatically fails over to a standby when the primary DB instance becomes unavailable. Which approach best meets the requirement with minimal operational effort?
Question 11hardmulti select
Full question →A distributed analytics engine runs 12 EC2 instances in one Availability Zone. The nodes exchange thousands of tiny messages per second and must keep jitter as low as possible. The current design launches the instances across multiple placement groups and uses general-purpose burstable instances. Which two changes will most directly lower east-west network latency and variability? Select two.
Question 12mediummultiple choice
Full question →A high-frequency trading analytics service runs on several EC2 instances in the same Availability Zone. The application exchanges small messages between nodes and is sensitive to microsecond-level network latency. Which design best meets the requirement?
Question 13mediummulti select
Full question →A distributed analytics platform runs on 12 EC2 instances in one Availability Zone. The nodes exchange a very high volume of east-west messages and the team wants the lowest possible network latency between instances. Which two changes should the architect make first? Select two.
Question 14mediummulti select
Full question →A distributed simulation launches 40 EC2 instances that exchange small packets frequently and are sensitive to cross-instance latency. The workload stays in one Availability Zone and can use the same instance family across nodes. Which two choices improve network performance the most? Select two.
Question 15hardmulti select
Full question →A retail analytics table stores events in Amazon DynamoDB with partition key tenantId and sort key eventTime. During a promotion, one tenant generates most writes and repeatedly polls the same latest-status items, causing throttling on a single partition key and high latency on reads. The business can tolerate read results that are a few seconds stale. Which two changes will most effectively reduce throttling and latency? Select two.
Question 16mediummultiple choice
Full question →A research team runs a latency-sensitive distributed training job on Amazon EC2. They deploy 80 identical nodes that exchange small messages frequently and need low network jitter. The job must run entirely within one Availability Zone. Which placement group strategy should a solutions architect use to maximize intra-cluster network performance?
Question 17easymulti select
Full question →A production Amazon RDS database must continue serving the application if the primary DB instance fails. The application should reconnect automatically without hard-coding a new IP address. Which two actions should you take? Select two.
Question 18mediummultiple choice
Full question →A media processing service runs ECS tasks in multiple Availability Zones. Each task must read and write the same shared filesystem with low latency because tasks stream intermediate artifacts to other tasks. The team currently mounts an EBS volume per task, and cross-AZ tasks frequently cannot see each other’s files. Which option best resolves the shared filesystem requirement while supporting high-performing access?
Question 19mediummultiple choice
Full question →A SaaS platform serves an API using two regional deployments: us-east-1 (primary) and us-west-2 (secondary). Each region has its own ALB. The business requires automated DNS-based failover when the primary region becomes unhealthy, and they do not want manual DNS changes during incidents.
Which Route 53 configuration is the best match?

Watch out for
Common High Availability exam traps
- ▸Answering from memory before reading the full scenario.
- ▸Missing a constraint such as cost, availability, security, scope or command context.
- ▸Choosing a broad answer when the question asks for the most specific fix.
- ▸Ignoring why the wrong options are tempting.

Frequently asked questions
- What does the SAA-C03 exam test about High Availability?
- High Availability questions test whether you can apply the concept in context, not just recognise a definition.
- 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 High Availability questions in a focused session?
- Yes — the session launcher on this page draws every question from the High Availability 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 SAA-C03 topics?
- Use the topic links above to move to related areas, or go back to the SAA-C03 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 SAA-C03 exam covers. They are not copied from any real exam or dump site.
