20+ practice questions focused on Network Security, Compliance and Governance — one of the most tested topics on the AWS Certified Advanced Networking Specialty ANS-C01 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Network Security, Compliance and Governance PracticeA company wants to enforce that all outbound traffic from its VPC flows through a centralized inspection VPC for security monitoring. The VPCs are connected via Transit Gateway. Which set of actions should a network engineer take to ensure that traffic from application VPCs is routed to the inspection VPC before reaching the internet?
Explanation: Option D is correct because it uses separate Transit Gateway route tables to enforce traffic isolation: the application VPC attachments use a route table with a blackhole for 0.0.0.0/0, preventing direct internet access, while the inspection VPC uses a different route table with a route to an egress VPC that has an internet gateway. This ensures all outbound traffic from application VPCs must first traverse the inspection VPC for security monitoring before reaching the internet.
A security engineer is designing a network security architecture for a multi-account AWS environment using AWS Organizations. The company requires that all VPC flow logs be delivered to a central S3 bucket in the security account. The security engineer has created a bucket policy that grants the necessary permissions. However, flow logs from member accounts are failing to be delivered. What is the most likely cause?
Explanation: Option B is correct because the VPC Flow Logs delivery service uses a service-linked role to write to the destination S3 bucket. Without a condition in the bucket policy that restricts access using `aws:SourceArn` or `aws:SourceAccount`, the policy is vulnerable to the confused deputy problem, where a different AWS service or account could potentially write to the bucket. The missing condition causes the delivery to fail because the service cannot verify that the request originated from the expected source.
A company is using AWS Direct Connect to connect its on-premises network to AWS. The company wants to encrypt all traffic between its on-premises network and AWS. Which solution meets this requirement?
Explanation: Option B is correct because AWS Direct Connect does not natively encrypt traffic; it provides a private, dedicated network connection. To meet the encryption requirement, you can establish an IPsec VPN tunnel over the private VIF, which encrypts all traffic between the on-premises network and the VPC. This approach combines the low latency and reliability of Direct Connect with the security of IPsec encryption.
A company has a VPC with a public subnet and a private subnet. An EC2 instance in the private subnet needs to initiate outbound connections to the internet for software updates. The company wants to ensure that all outbound traffic goes through a single, highly available IP address for whitelisting purposes. Which solution should be used?
Explanation: Option B is correct because a NAT gateway in each AZ provides high availability and a single elastic IP per AZ, but if you need a single IP, you can use a single NAT gateway in one AZ (with a single EIP) or use a NAT instance with an EIP. However, the requirement is highly available and single IP. A NAT gateway in each AZ would have multiple IPs. Option A is wrong because NAT instance is not highly available. Option C is wrong because internet gateway in private subnet is not allowed. Option D is wrong because VPC endpoint for S3 does not provide internet access.
A company wants to audit all changes made to security groups and network ACLs in its AWS account. Which AWS service should be used to capture these API calls?
Explanation: AWS CloudTrail is the correct service because it records all API calls made to the AWS environment, including those that modify security groups and network ACLs. By enabling CloudTrail, you can capture CreateSecurityGroup, AuthorizeSecurityGroupIngress, RevokeSecurityGroupEgress, CreateNetworkAclEntry, and similar API calls, providing an audit trail of who made the change, when, and from which IP address.
