Question 2hardmultiple choice
Full question →A media processing workflow in private subnets downloads large amounts of data from S3 through a NAT gateway. NAT data processing charges are high. What should the architect use to reduce cost? The architecture review board prefers a managed AWS-native control.
Question 3hardmultiple choice
Full question →A batch analytics job currently uses two NAT gateways in each of three Availability Zones, but only one private subnet per AZ needs outbound internet access. What should the architect review first?
Question 4hardmultiple choice
Full question →A batch analytics job currently uses two NAT gateways in each of three Availability Zones, but only one private subnet per AZ needs outbound internet access. What should the architect review first? The design must avoid adding custom operational scripts.
Question 5hardmulti select
Full question →A CI system runs on EC2 instances in private subnets and uploads build artifacts to an S3 bucket. The security team wants to eliminate NAT Gateway costs, force all uploads to use TLS, and require SSE-KMS with an approved customer managed key. Which three changes should be made? Select three.
Question 6mediummultiple choice
Full question →A company hosts application servers in private subnets. They must access Amazon S3 and read secrets from AWS Secrets Manager, but they want to avoid internet egress. They currently use a NAT gateway and see high NAT-related costs. What change most directly reduces cost while keeping traffic on the AWS network?
Question 7mediummultiple choice
Full question →A company hosts an internal HTTP API on an internal Network Load Balancer (NLB) in VPC A. A partner team in a separate AWS account needs access, but their VPC CIDR overlaps with VPC A, so VPC peering is not feasible.
Security requirements state the API must remain non-public (no internet-facing ALB/NLB) and access must use AWS private networking.
Which architecture best meets these requirements?
Question 8easymulti select
Full question →A company hosts an internal API in two AWS Regions. Traffic must automatically switch to the secondary Region when the primary Region's endpoint is unhealthy. Which two Route 53 settings are required? Select two.
Question 9mediummultiple choice
Full question →A company runs an application in private subnets (no inbound internet). The application must access Amazon S3 and AWS Secrets Manager endpoints without routing through the public internet and without exposing the instances to NAT gateways due to cost. Security requirements also state that only the required VPC traffic should be allowed to reach AWS services.
Which architecture best satisfies these requirements?
Question 10hardmulti select
Full question →A batch job runs on EC2 instances in isolated private subnets with no NAT Gateway. The job uses STS AssumeRole to access an operations account and then retrieves a secret from AWS Secrets Manager. After a network hardening change, both calls fail. Which two interface VPC endpoints should be created? Select two.
Question 11mediummultiple choice
Full question →A company hosts an internal HTTP API on an internal Network Load Balancer (NLB) in VPC A. A partner team in a separate AWS account needs access, but their VPC CIDR overlaps with VPC A, so VPC peering is not feasible.
Security requirements state the API must remain non-public (no internet-facing ALB/NLB) and access must use AWS private networking.
Which architecture best meets these requirements?
Question 12mediummultiple choice
Full question →A company hosts an application on EC2 instances in private subnets. The instances must (1) read objects from Amazon S3 and (2) retrieve secrets from AWS Secrets Manager. The team currently sends all outbound traffic through a NAT gateway to reach both services. They want to reduce monthly cost while keeping traffic private (no internet egress) and without changing application logic. Which change is the most cost-effective?
Question 13mediummultiple choice
Full question →A company runs an application on EC2 instances in private subnets. The instances must access Amazon S3, and the team currently routes all outbound traffic to the internet through a NAT Gateway. Monthly NAT Gateway charges increased significantly, even though the application only needs to call S3 (not access other public internet services). Which change will most directly reduce NAT Gateway charges while keeping S3 access working?
Question 14mediummultiple choice
Full question →A company uses Amazon RDS for a PostgreSQL database powering a customer-facing application. The application’s availability depends on fast database failover with minimal manual intervention. The RDS instance currently runs as a single-AZ deployment in one DB subnet group. Which change most directly meets the goal?
Question 15easymultiple choice
Full question →A company’s private workload in a VPC uploads objects to an S3 bucket. Security requires that S3 requests are allowed only when they traverse a specific S3 Gateway VPC Endpoint (vpce-0abc123example). Which change best enforces this restriction at the S3 bucket level?
Question 16easymultiple choice
Full question →A company runs EC2 instances in private subnets and needs to access Amazon S3 objects without using a NAT gateway. They want the traffic to stay within AWS private networking as much as possible (no internet egress). Which VPC endpoint type should they create for Amazon S3?
Question 17mediummultiple choice
Full question →A company uses Amazon RDS for a PostgreSQL database powering a customer-facing application. The application’s availability depends on fast database failover with minimal manual intervention. The RDS instance currently runs as a single-AZ deployment in one DB subnet group. Which change most directly meets the goal?
Question 18mediummultiple choice
Full question →A company runs an application in private subnets (no inbound internet). The application must access Amazon S3 and AWS Secrets Manager endpoints without routing through the public internet and without exposing the instances to NAT gateways due to cost. Security requirements also state that only the required VPC traffic should be allowed to reach AWS services.
Which architecture best satisfies these requirements?
Question 19mediummultiple choice
Full question →A company runs an application behind an Application Load Balancer (ALB). An Auto Scaling group (ASG) is configured with desired capacity 2, but it is attached only to subnets in a single Availability Zone. The ALB is healthy because it is configured across multiple Availability Zones.
When the Availability Zone that contains the ASG subnets experiences an outage, what change most directly improves resilience and allows capacity to be restored automatically?
Question 20hardmultiple choice
Full question →A dev sandbox currently uses two NAT gateways in each of three Availability Zones, but only one private subnet per AZ needs outbound internet access. What should the architect review first? The design must avoid adding custom operational scripts.
Watch out for
Common VPC 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 VPC?
- VPC 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 VPC questions in a focused session?
- Yes — the session launcher on this page draws every question from the VPC 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.
