NEW QUESTION # 81
An application is running on an Amazon EC2 instance that has an IAM role attached. The IAM role provides access to an AWS Key Management Service (AWS KMS) customer managed key and an Amazon S3 bucket. The key is used to access 2 TB of sensitive data that is stored in the S3 bucket. A security engineer discovers a potential vulnerability on the EC2 instance that could result in the compromise of the sensitive data. Due to other critical operations, the security engineer cannot immediately shut down the EC2 instance for vulnerability patching. What is the FASTEST way to prevent the sensitive data from being exposed?
Answer: D
Explanation:
AWS incident response best practices emphasize rapid containment to prevent further data exposure. According to the AWS Certified Security - Specialty Study Guide, the fastest and least disruptive containment method for compromised compute resources is to immediately revoke credentials and permissions rather than modifying data or infrastructure.
Revoking the IAM role's active sessions prevents the EC2 instance from continuing to access AWS services. Updating the S3 bucket policy to explicitly deny access to the IAM role ensures immediate enforcement, even if temporary credentials remain cached. Removing the IAM role from the instance profile further prevents new credentials from being issued.
Option A and D involve large-scale data movement or re-encryption, which is time-consuming and operationally expensive. Option B relies on network-level controls that do not prevent access through private AWS endpoints.
AWS guidance explicitly recommends credential revocation and policy-based denial as the fastest containment step during active incidents.
NEW QUESTION # 82
A security engineer needs to configure DDoS protection for a Network Load Balancer (NLB) with an Elastic IP address. The security engineer wants to set up an AWS WAF web ACL with a rate-based rule statement to protect the NLB.
The security engineer needs to determine a rate limit that will not block legitimate traffic. The security engineer has configured the rule statement to aggregate based on the source IP address.
How should the security engineer configure the rule to protect the NLB?
Answer: C
Explanation:
AWS WAF rate-based rules are designed to help protect applications and resources fromtraffic floods and application-layer DDoS attacksby tracking the number of requests from individual source IP addresses over a rolling time window. According to the AWS Certified Security - Specialty Official Study Guide and AWS WAF documentation, rate-based rules can be configured with different actions, includingCount,Block, and Allow.
When a security engineer is determining an appropriate rate limit that will not block legitimate traffic, AWS best practices recommend initially configuring the rate-based rule with theCountaction. The Count action allows AWS WAF tomonitor and log requests that exceed the specified rate threshold without actively blocking them. This provides visibility into traffic patterns and enables the security engineer to analyze how the rule would behave in production.
By using the Count action, the security engineer can safely evaluate whether legitimate users would be affected by the chosen rate limit. Once the engineer is confident that the threshold accurately distinguishes between normal traffic and malicious behavior, the action can later be changed to Block.
Option B is incorrect because immediately blocking traffic without validation risks denying service to legitimate users. Option C is invalid because AWS WAF does not have a Monitor action. Option D is incorrect because the Allow action does not enforce rate limiting.
AWS documentation explicitly recommendsstarting rate-based rules in Count modeto fine-tune thresholds before enforcing blocks, especially for DDoS protection scenarios.

NEW QUESTION # 84
A systems administrator was attempting to launch a new Amazon EC2 instance with an encrypted boot volume using a new AWS KMS customer managed key. The EC2 console initially stated the launch was successful, but the instance was subsequently terminated. The IAM role used by the systems administrator has the following IAM permissions:
* ec2:Describe*
* ec2:AuthorizeSecurityGroupIngress
* kms:Encrypt
* kms:Decrypt
* kms:ReEncrypt*
* kms:GenerateDataKey*
* kms:DescribeKey
Which IAM permission is the systems administrator missing?
Answer: C
Explanation:
Comprehensive and Detailed 100to 150 words of Explanation From AWS Certified Security - Specialty topics:
When EC2 launches an instance with an encrypted EBS boot volume that uses a customer managed KMS key, AWS services must be able to use the key on behalf of the instance workflow. KMS grants are commonly required so the integrated AWS service can use the customer managed key for EBS encryption operations.
Without kms:CreateGrant, the launch can appear to start but later fail when EC2/EBS cannot establish the needed grant to use the key. GetKeyRotationStatus only reads rotation configuration, GenerateRandom is unrelated to EBS encryption, and EnableKey is an administrative action for re-enabling a disabled key. The missing operational permission for encrypted volume launch is CreateGrant.
NEW QUESTION # 85
A company ' s public website consists of an Application Load Balancer (ALB), a set of Amazon EC2 instances that run a stateless application behind the ALB, and an Amazon DynamoDB table from which the application reads data. The company is concerned about malicious scanning and DDoS attacks. The company wants to impose a restriction in which each client IP address can read the data only3 times in any 5-minute period.
Which solution will meet this requirement with the LEAST effort?
Answer: D
Explanation:
This is a classic Layer 7 rate-limiting requirement tied toclient IPand atime window, and AWS WAF provides this natively withrate-based rules. Placing AWS WAF in front of the ALB allows the company to count requests per source IP over a rolling window and take action (block, CAPTCHA/challenge, or count depending on configuration) once the threshold is exceeded. This approach mitigates scanning and application-layer request floods early, before requests consume EC2 or DynamoDB capacity, and it requires minimal custom code or operational work.
Options B and C require building and maintaining custom counting logic (either in Lambda or in the application), which increases complexity and risk of errors, and it also introduces operational overhead for scaling state tracking across many IPs. Option D is not appropriate: altering DynamoDB capacity does not enforce "per-IP reads," and storing per-request metadata in the same table is an anti-pattern that increases write load and complexity.
Therefore, using AWS WAF rate-based protection at the ALB is the least-effort, most effective solution.
