QUESTION: 76

A company is using Amazon S3 buckets to store important documents. The company discovers that some S3 buckets are not encrypted. Currently, the company's IAM users can create new S3 buckets without encryption. The company is implementing a new requirement that all S3 buckets must be encrypted.

A DevOps engineer must implement a solution to ensure that server-side encryption is enabled on all existing S3 buckets and all new S3 buckets. The encryption must be enabled on new S3 buckets as soon as the S3 buckets are created. The default encryption type must be 256-bit Advanced Encryption Standard (AES-256).

Which solution will meet these requirements?

Create an AWS Lambda function that is invoked periodically by an Amazon EventBridge scheduled rule.
Program the Lambda function to scan all current S3 buckets for encryption status and to set AES-256 as the default encryption for any S3 bucket that does not have an encryption configuration.
Set up and activate the s3-bucket-server-side-encryption-enabled AWS Config managed rule. Configure the rule to use the AWS-EnableS3BucketEncryption AWS Systems Manager Automation runbook as the remediation action. Manually run the re-evaluation process to ensure that existing S3 buckets are compliant.
Create an AWS Lambda function that is invoked by an Amazon EventBridge event rule. Define the rule with an event pattern that matches the creation of new S3 buckets. Program the Lambda function to parse the EventBridge event, check the configuration of the S3 buckets from the event, and set AES-256 as the default encryption.
Configure an IAM policy that denies the s3:CreateBucket action if the s3:x-amz-server-side-encryption condition key has a value that is not AES-256. Create an IAM group for all the company's IAM users.
Associate the IAM policy with the IAM group.

QUESTION: 78

A company is hosting a static website from an Amazon S3 bucket. The website is available to customers at example.com. The company uses an Amazon Route 53 weighted routing policy with a TTL of 1 day. The company has decided to replace the existing static website with a dynamic web application. The dynamic web application uses an Application Load Balancer (ALB) in front of a fleet of Amazon EC2 instances.

On the day of production launch to customers, the company creates an additional Route 53 weighted DNS record entry that points to the ALB with a weight of 255 and a TTL of 1 hour. Two days later, a DevOps engineer notices that the previous static website is displayed sometimes when customers navigate to example.com.

How can the DevOps engineer ensure that the company serves only dynamic content for example.com?

Delete all objects, including previous versions, from the S3 bucket that contains the static website content.
Update the weighted DNS record entry that points to the S3 bucket. Apply a weight of 0. Specify the domain reset option to propagate changes immediately.
Configure webpage redirect requests on the S3 bucket with a hostname that redirects to the ALB.
Remove the weighted DNS record entry that points to the S3 bucket from the example.com hosted zone.
Wait for DNS propagation to become complete.

This AI Tutor is designed to help you connect the dots between different AWS services and understand why a specific solution is the most appropriate choice in a given scenario.

A common mistake candidates make when preparing for this certification exam is focusing too much on rote memorization of service features rather than understanding the architectural patterns that the exam tests. The DOP-C02 is a professional-level exam, which means it tests your ability to make trade-offs and design decisions based on specific business requirements. To avoid this pitfall, you should focus on understanding the "why" behind every configuration choice, such as why you would choose one deployment strategy over another in a specific context. Additionally, many candidates struggle with time management during the exam because they spend too long on complex, multi-part scenarios. You should practice answering questions under timed conditions to build the stamina and speed required to complete the exam within the allotted time frame.

What to Expect on Exam Day

On the day of your exam, you should expect a format that primarily consists of multiple-choice and multiple-response questions, often presented as complex, scenario-based problems. These scenarios will describe a specific business or technical challenge, and you will be asked to select the best solution from a list of options that may all seem plausible at first glance. The exam is administered through a professional testing environment, such as Pearson VUE, which ensures a secure and standardized testing experience. You will have a set amount of time to complete the exam, and it is important to manage your time carefully, as some questions may require more reading and analysis than others. Amazon certification exams are designed to test your ability to think critically under pressure, so being prepared for the format is just as important as knowing the technical content.

The testing environment will be strictly controlled, and you will not have access to any external resources or notes during the exam. It is important to familiarize yourself with the testing interface beforehand if possible, so you are comfortable with how to flag questions for review or navigate between sections. Because the DOP-C02 is a professional-level exam, the questions are often lengthy and require you to synthesize information from multiple sources to arrive at the correct conclusion. You should approach each question by identifying the core requirement or constraint mentioned in the scenario, as this will often point you toward the correct AWS service or architectural pattern. Staying calm and focused throughout the duration of the exam is essential for success, especially when you encounter difficult questions that require careful deliberation.
