Use AWS CloudTrail to create a new trail. Configure the trail to log read and write management events on the S3 bucket that houses the reports. Log these events to a new bucket, and enable log file validation.
C. Use AWS CloudTrail to create a new trail. Configure the trail to log read and write data events on the S3 bucket that houses the reports Log these events to a new bucket, and enable log file validation
A company's website handles millions of requests each day. and the number of requests continues to increase. A solutions architect needs to improve the response time of the web application. The solutions architect determines that the application needs to decrease latency when retrieving product details from the Amazon DynamoDB table
A. Set up a DynamoOB Accelerator (DAX) cluster Route all read requests through DAX. B. Set up Amazon ElasliCache (or Redis between the DynamoOB table and the web application.Route all read requests through Redis. C. Set up Amazon ElasliCache for Memcached between the DynamoOB table and the web application Route all read requests through Memcached. D. Set up Amazon DynamoOB Streams on the table, and have AWS Lambda read from the table and populate Amazon ElastiCache. Route all read requests through ElasliCache
A. Set up a DynamoOB Accelerator (DAX) cluster Route all read requests through DAX.
Question 586:
A company uses an Amazon S3 bucket to store static images for its website. The company configured permissions to allow access to Amazon S3 objects by privileged users only. What should a solutions architect do to protect against data loss? (Select TWO.)
A. Enable versioning on the S3 bucket B. Enable access logging on the S3 bucket C. Enable server-side encryption on the S3 bucket. D. Configure an S3 Lifecycle rule to transition objects to Amazon S3 Glacier. E. Use MFA Delete to require multi-factor authentication to delete an object
A. Enable versioning on the S3 bucket E. Use MFA Delete to require multi-factor authentication to delete an object
Question 587:
A company needs to run its external website on Amazon EC2 instances and on-premises virtualized servers The AWS environment has a 1 GB AWS Direct Connect connection to the data center. The application has IP addresses that will not change. The on-premises and AWS servers are able to restart themselves while maintaining the same IP address if a failure occurs Some website users have to add their vendors to an allow list, so the solution must have a fixed IP address The company needs a solution with the lowest operational overhead to handle this split traffic.
What should a solutions architect do to meet these requirements?
A. Deploy an Amazon Route 53 Resolver with rules pointing to the on-premises and AWS IP addresses B. Deploy a Network Load Balancer on AWS. Create target groups for the on-premises and AWS IP addresses. C. Deploy an Application Load Balancer on AWS Register the on-premises and AWS IP addresses with the target group. D. Deploy Amazon API Gateway to direct traffic to the on-premises and AWS IP addresses based on the header of the request.
B. Deploy a Network Load Balancer on AWS. Create target groups for the on-premises and AWS IP addresses.

Question 588:
A company's application is running on Amazon EC2 instances within an Auto Scaling group behind an Elastic Load Balancer Based on the application's history, the company anticipates a spike in traffic during a holiday each year. A solutions
architect must design a strategy to ensure that the Auto Scaling group proactively increases capacity lo minimize any performance impact on application users.
Which solution will meet these requirements?

Explanation/Reference:
AWS Global Accelerator Acceleration for latency-sensitive applications Many applications, especially in areas such as gaming, media, mobile apps, and financials, require very low latency for a great user experience. To improve the user experience, Global Accelerator directs user traffic to the application endpoint that is nearest to the client, which reduces internet latency and jitter. Global Accelerator routes traffic to the closest edge location by using Anycast, and then routes it to the closest regional endpoint over the AWS global network. Global Accelerator quickly reacts to changes in network performance to improve your users' application performance. Amazon CloudFront Amazon CloudFront is a fast content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency, high transfer speeds, all within a developer-friendly environment.
