NEW QUESTION # 192
A developer is updating an Amazon API Gateway REST API to have a mock endpoint. The developer wants to update the integration request mapping template so the endpoint will respond to mock integration requests with specific HTTP status codes based on various conditions.
Which statement will meet these requirements?
Answer: C
NEW QUESTION # 193
An ecommerce startup is preparing for an annual sales event. As the traffic to the company's application increases, the development team wants to be notified when the Amazon EC2 instance's CPU utilization exceeds 80%.
Which solution will meet this requirement?
Answer: A
Explanation:
Step-by-Step Breakdown:
Requirement Summary:
* Get notified when EC2 CPU Utilization > 80%
Option A: CloudWatch Alarm with SNS
* Correct and standard AWS practice
* CloudWatch automatically collects EC2 metrics, including CPUUtilization.
* You can set a CloudWatch Alarm with a threshold (80% in this case).
* Then, trigger an SNS notification to email, SMS, Lambda, etc.
Option B: AWS CloudTrail alarm
* Incorrect: CloudTrail logs API activity, not performance metrics.
* It doesn't track metrics like CPU utilization.
Option C: Cron job on EC2 running --describe-instance-information
* Incorrect: This doesn't give CPU usage.
* Also inefficient, and polling is bad practice when CloudWatch already monitors this natively.
Option D: Lambda function querying CloudTrail for CPU usage
* Incorrect and conceptually flawed.
* CloudTrail does not store performance metrics; CloudWatch does.

NEW QUESTION # 194
A company has an application that is hosted on Amazon EC2 instances The application stores objects in an Amazon S3 bucket and allows users to download objects from the S3 bucket A developer turns on S3 Block Public Access for the S3 bucket After this change, users report errors when they attempt to download objects The developer needs to implement a solution so that only users who are signed in to the application can access objects in the S3 bucket.
Which combination of steps will meet these requirements in the MOST secure way? (Select TWO.)
Answer: C,E
Explanation:
* IAM Roles for EC2 (A): The most secure way to provide AWS permissions from EC2.
* Create a role with a policy allowing s3:GetObject on the specific bucket.
* Attach the role to an instance profile and associate that profile with your instances.
* Pre-signed URLs (C): Temporary, authenticated URLs for specific S3 actions.
* Modify the app to use the AWS SDK to call GeneratePresignedUrl.
* Embed these URLs when a user is properly logged in, allowing download access.

NEW QUESTION # 195
A developer is testing a new file storage application that uses an Amazon CloudFront distribution to serve content from an Amazon S3 bucket. The distribution accesses the S3 bucket by using an origin access identity (OAI). The S3 bucket's permissions explicitly deny access to all other users.
The application prompts users to authenticate on a login page and then uses signed cookies to allow users to access their personal storage directories. The developer has configured the distribution to use its default cache behavior with restricted viewer access and has set the origin to point to the S3 bucket. However, when the developer tries to navigate to the login page, the developer receives a 403 Forbidden error.
The developer needs to implement a solution to allow unauthenticated access to the login page. The solution also must keep all private content secure.
Which solution will meet these requirements?
Answer: D
Explanation:
The solution that will meet the requirements is to add a second cache behavior to the distribution with the same origin as the default cache behavior. Set the path pattern for the second cache behavior to the path of the login page, and make viewer access unrestricted. Keep the default cache behavior's settings unchanged. This way, the login page can be accessed without authentication, while all other content remains secure and requires signed cookies. The other options either do not allow unauthenticated access to the login page, or expose private content to unauthorized users.

NEW QUESTION # 196
Users of a web-based music application are experiencing latency issues on one of the application ' s most popular pages. A developer identifies that the issue is caused by the slow load time of specific widgets that rank and sort various songs and albums.
The developer needs to ensure that the widgets load more quickly by using built-in, in-memory ranking and sorting techniques. The developer must ensure that the data remains up to date.
Which solution will meet these requirements with the LEAST latency ?
Answer: A
Explanation:
Comprehensive and Detailed 250 to 300 words of Explanation (AWS-doc-aligned):
To minimize widget latency for ranking and sorting, the best fit is Amazon ElastiCache for Redis OSS because Redis provides built-in in-memory data structures specifically suited for ranking use cases, such as Sorted Sets (ZSETs) . Sorted sets maintain members in order by score, which enables fast retrieval of "top N" items and efficient re-ranking without repeatedly querying the primary database and sorting at the application tier. Memcached, by contrast, is a simpler key-value cache and does not provide comparable native ranking/sorting data structures.
To ensure data remains up to date , a write-through caching strategy is preferred. With write-through, updates are written to the cache at the same time as the system of record, so the cache reflects the latest values immediately after writes. This avoids stale rankings that can occur with lazy-loading (cache-aside), where the cache is only populated or refreshed on reads and can serve older data until expiration or explicit invalidation.
Combining Redis's native sorted/ranking structures with write-through updates yields the least latency because the page widgets can fetch pre-ranked/pre-sorted results directly from Redis memory with minimal computation, while still maintaining freshness as new plays, likes, or album changes occur. Operationally, this pattern reduces database load, avoids repeated sorting work in the application, and provides consistently fast reads for a high-traffic page.
