A company has a new security policy. The policy requires the company to log any event that retrieves data from Amazon S3 buckets. The company must save these audit logs in a dedicated S3 bucket. The company created the audit logs S3 bucket in an AWS account that is designated for centralized logging. The S3 bucket has a bucket policy that allows write-only cross-account access A solutions architect must ensure that all S3 object-level access is being logged for current S3 buckets and future S3 buckets. Which solution will meet these requirements?

1. A. Enable server access logging for all current S3 bucket
2. B. Use the audit logs S3 bucket as a destination foraudit logs
3. C. Enable replication between all current S3 buckets and the audit logs S3 bucket Enable S3 Versioning in the audit logs S3 bucket
4. D. Configure S3 Event Notifications for all current S3 buckets to invoke an AWS Lambda function every time objects are accessed . Store Lambda logs in the audit logs S3 bucket.
5. E. Enable AWS CloudTrai
6. F. and use the audit logs S3 bucket to store logs Enable data event logging for S3 event sources, current S3 buckets, and future S3 buckets.

Correct Answer: D

A company is running a three-tier web application in an on-premises data center. The frontend is served by an Apache web server, the middle tier is a monolithic Java application, and the storage tier is a PostgreSOL database.
During a recent marketing promotion, customers could not place orders through the application because the application crashed An analysis showed that all three tiers were overloaded. The application became unresponsive, and the database reached its capacity limit because of read operations. The company already has several similar promotions scheduled in the near future.
A solutions architect must develop a plan for migration to AWS to resolve these issues. The solution must maximize scalability and must minimize operational effort.
Which combination of steps will meet these requirements? (Select THREE.)

1. A. Refactor the frontend so that static assets can be hosted on Amazon S3. Use Amazon CloudFront to serve the frontend to customer
2. B. Connect the frontend to the Java application.
3. C. Rehost the Apache web server of the frontend on Amazon EC2 instances that are in an Auto Scaling grou
4. D. Use a load balancer in front of the Auto Scaling grou
5. E. Use Amazon Elastic File System (Amazon EFS) to host the static assets that the Apache web server needs.
6. F. Rehost the Java application in an AWS Elastic Beanstalk environment that includes auto scaling.
7. G. Refactor the Java applicatio
8. H. Develop a Docker container to run the Java applicatio
9. I. Use AWS Fargate to host the container.
10. J. Use AWS Database Migration Service (AWS DMS) to replatform the PostgreSQL database to an Amazon Aurora PostgreSQL databas
11. K. Use Aurora Auto Scaling for read replicas.
12. L. Rehost the PostgreSQL database on an Amazon EC2 instance that has twice as much memory as the on-premises server.

Correct Answer: BCF

A company built an ecommerce website on AWS using a three-tier web architecture. The application is
Java-based and composed of an Amazon CloudFront distribution, an Apache web server layer of Amazon EC2 instances in an Auto Scaling group, and a backend Amazon Aurora MySQL database.
Last month, during a promotional sales event, users reported errors and timeouts while adding items to their shopping carts. The operations team recovered the logs created by the web servers and reviewed Aurora DB cluster performance metrics. Some of the web servers were terminated before logs could be collected and the Aurora metrics were not sufficient for query performance analysis.
Which combination of steps must the solutions architect take to improve application performance visibility during peak traffic events? (Select THREE.)

1. A. Configure the Aurora MySQL DB cluster to publish slow query and error logs to Amazon CloudWatch Logs.
2. B. Implement the AWS X-Ray SDK to trace incoming HTTP requests on the EC2 instances and implement tracing of SQL queries with the X-Ray SDK for Java.
3. C. Configure the Aurora MySQL DB cluster to stream slow query and error logs to Amazon Kinesis.
4. D. Install and configure an Amazon CloudWatch Logs agent on the EC2 instances to send the Apache logsto CloudWatch Logs.
5. E. Enable and configure AWS CloudTrail to collect and analyze application activity from Amazon EC2 and Aurora.
6. F. Enable Aurora MySQL DB cluster performance benchmarking and publish the stream to AWS X-Ray.

A company has developed a single-page web application in JavaScript. The source code is stored in a single Amazon S3 bucket in the us-east-1 Region. The company serves the web application to a global user base through Amazon CloudFront.
The company wants to experiment with two versions of the website without informing application users. Each version of the website will reside in its own S3 bucket. The company wants to determine which version is most successful in marketing a new product.
The solution must send application users that are based in Europe to the new website design. The solution must send application users that are based in the United States to the current website design. However, some exceptions exist. The company needs to be able to redirect specific users to the new website design, regardless of the users' location.
Which solution meets these requirements?

1. A. Configure two CloudFront distribution
2. B. Configure a geolocation routing policy in Amazon Route 53 to route traffic to the appropriate CloudFront endpoint based on the location of clients.
3. C. Configure a single CloudFront distributio
4. D. Create a behavior with different paths for each version of the sit
5. E. Configure Lambda@Edge on the default path to generate redirects and send the client to the correct version of the website.
6. F. Configure a single CloudFront distributio
7. G. Configure an alternate domain name on the distribution.Configure two behaviors to route users to the different S3 origins based on the domain name that the client uses in the HTTP request.
8. H. Configure a single CloudFront distribution with Lambda@Edg
9. I. Use Lambda@Edge to send user requests to different origins based on request attributes.

Correct Answer: A

A company runs an application that gives users the ability to search for videos and related information by using keywords that are curated from content providers. The application data is stored in an on-premises Oracle database that is 800 GB in size.
The company wants to migrate the data to an Amazon Aurora MySQL DB instance. A solutions architect
plans to use the AWS Schema Conversion Tool and AWS Database Migration Service (AWS DMS) for the migration. During the migration, the existing database must serve ongoing requests. The migration must be completed with minimum downtime
Which solution will meet these requirements?

1. A. Create primary key indexes, secondary indexes, and referential integrity constraints in the target database before starting the migration process
2. B. Use AWS DMS to run the conversion report for Oracle to Aurora MySQ
3. C. Remediate any issues Then use AWS DMS to migrate the data
4. D. Use the M5 or CS DMS replication instance type for ongoing replication
5. E. Turn off automatic backups and logging of the target database until the migration and cutover processes are complete
