Question 12

A company has Amazon EC2 instances in multiple AWS Regions. The instances all store and retrieve confidential data from the same Amazon S3 bucket. The company wants to improve the security of its current architecture.

The company wants to ensure that only the Amazon EC2 instances within its VPC can access the S3 bucket. The company must block all other access to the bucket.

Which solution will meet this requirement?

Options:

Use IAM policies to restrict access to the S3 bucket.

Use server-side encryption (SSE) to encrypt data in the S3 bucket at rest. Store the encryption key on the EC2 instances.

Create a VPC endpoint for Amazon S3. Configure an S3 bucket policy to allow connections only from the endpoint.

Use AWS Key Management Service (AWS KMS) with customer-managed keys to encrypt the data before sending the data to the S3 bucket.

Question 13

A weather forecasting company collects temperature readings from various sensors on a continuous basis. An existing data ingestion process collects the readings and aggregates the readings into larger Apache Parquet files. Then the process encrypts the files by using client-side encryption with KMS managed keys (CSE-KMS). Finally, the process writes the files to an Amazon S3 bucket with separate prefixes for each calendar day.

The company wants to run occasional SQL queries on the data to take sample moving averages for a specific calendar day.

Which solution will meet these requirements MOST cost-effectively?

Options:

Configure Amazon Athena to read the encrypted files. Run SQL queries on the data directly in Amazon S3.

Use Amazon S3 Select to run SQL queries on the data directly in Amazon S3.

Configure Amazon Redshift to read the encrypted files Use Redshift Spectrum and Redshift query editor v2 to run SQL queries on the data directly in Amazon S3.

Configure Amazon EMR Serverless to read the encrypted files. Use Apache SparkSQL to run SQL queries on the data directly in Amazon S3.

Question 15

A companyQUESTION NO: 24

A company has launched an Amazon RDS for MySQL DB instance. Most of the connections to the database come from serverless applications. Application traffic to the database changes significantly at random intervals. At times of high demand, users report that their applications experience database connection rejection errors.

Which solution will resolve this issue with the LEAST operational overhead?

Options:

Create a proxy in RDS Proxy. Configure the users' applications to use the DB instance through RDS Proxy.

Deploy Amazon ElastiCache (Memcached) between the users' applications and the DB instance.

Migrate the DB instance to a different instance class that has higher I/O capacity. Configure the users' applications to use the new DB instance.

Configure Multi-AZ for the DB instance. Configure the users' applications to switch between the DB instances.
