ANS-C01 Network Implementation Practice Question

This ANS-C01 practice question tests your understanding of network implementation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company is deploying a multi-tier web application on AWS. The application uses an Application Load Balancer (ALB) to distribute traffic to EC2 instances in private subnets across multiple Availability Zones. The security team requires that all traffic between the ALB and the EC2 instances be encrypted using TLS. The application must also support HTTP health checks from the ALB. Which TWO actions should the network engineer take to meet these requirements? (Choose TWO.)

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Install a certificate on each EC2 instance and configure the target group to use HTTPS.

Option B is correct because installing a certificate on each EC2 instance and configuring the target group to use HTTPS ensures that traffic between the ALB and the EC2 instances is encrypted using TLS. This meets the security requirement for end-to-end encryption, as the ALB will establish a TLS connection with the instances using the installed certificate.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Configure the ALB listener to use HTTP and enable stickiness.

    Why it's wrong here

    ALB listener should use HTTPS for encrypted traffic; stickiness is not required.

  • Install a certificate on each EC2 instance and configure the target group to use HTTPS.

    Why this is correct

    Installing a certificate on instances allows TLS termination, and HTTPS target group ensures encrypted health checks.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Configure the ALB listener to use HTTPS and set the target group protocol to HTTP.

    Why it's wrong here

    Setting target group to HTTP would send unencrypted traffic to instances.

  • Configure the target group health check to use HTTPS.

    Why this is correct

    HTTPS health checks ensure health checks are encrypted.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Configure the security group for EC2 instances to allow inbound HTTP traffic from the ALB.

    Why it's wrong here

    Security group should allow HTTPS (port 443) from the ALB, not HTTP.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often assume setting the ALB listener to HTTPS is sufficient for end-to-end encryption, overlooking that the target group protocol must also be HTTPS to encrypt the ALB-to-instance traffic.

Detailed technical explanation

How to think about this question

When using an ALB with HTTPS target groups, the ALB initiates a new TLS connection to the EC2 instances, requiring the instances to present a valid certificate. The health check must also use HTTPS to verify the endpoint's TLS configuration; otherwise, a plain HTTP health check might succeed even if the TLS handshake fails, masking misconfigurations. In practice, you can use self-signed certificates on the instances for internal traffic, as the ALB does not validate the certificate chain by default.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
