A workload in private subnets must upload logs to Amazon S3 and retrieve one secret from AWS Secrets Manager. The security team forbids internet egress and wants the lowest operational overhead. Which two VPC endpoints should be created? Select two.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
An Amazon S3 gateway endpoint for private S3 access.
S3 supports gateway endpoints, which route traffic through the AWS network without requiring a NAT gateway or internet gateway. This is the lowest-overhead private access option for S3.
B
Best answer
An AWS Secrets Manager interface endpoint for private secret retrieval.
Secrets Manager is accessed through an interface endpoint (AWS PrivateLink). This allows private subnet workloads to call the service without any internet route.
C
Distractor review
A NAT Gateway in the public subnet.
A NAT Gateway provides outbound internet access for private subnets. That violates the requirement to forbid internet egress and also adds cost and operational dependency.
D
Distractor review
An Internet Gateway attached to the VPC.
An Internet Gateway is used for public subnet routing and public internet access. It is unnecessary here and conflicts with the requirement to keep the workload private.
E
Distractor review
A DynamoDB gateway endpoint for the log upload path.
A DynamoDB endpoint is only for DynamoDB traffic. It does not help with S3 log uploads or Secrets Manager retrieval.
Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: An Amazon S3 gateway endpoint for private S3 access. — The workload needs two different endpoint types. S3 uses a gateway endpoint, which is simple to deploy and keeps traffic on the AWS backbone without NAT. Secrets Manager requires an interface endpoint because it is an API service reached through PrivateLink. Together, these endpoints satisfy the private-subnet requirement while avoiding internet egress and minimizing operational overhead. A NAT Gateway and an Internet Gateway both introduce internet-dependent routing, which the scenario forbids. A DynamoDB gateway endpoint does not apply to the services in question. The correct combination is the S3 gateway endpoint plus the Secrets Manager interface endpoint.
