Question 181
A company is hosting multiple websites for several lines of business under its registered parent domain. Users accessing these websites will be routed to appropriate backend Amazon EC2 instances based on the subdomain. The websites host static webpages, images, and server-side scripts like PHP andJavaScript.
Some of the websites experience peak access during the first two hours of business with constant usage throughout the rest of the day. A solutions architect needs to design a solution that will automatically adjust capacity to these traffic patterns while keeping costs low.
Which combination of AWS services or features will meet these requirements? (Choose two.)
A. AWS Batch
B. Network Load Balancer
C. Application Load Balancer
D. Amazon EC2 Auto Scaling
E. Amazon S3 website hosting
Question 182
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? (Choose 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.
Question 183
An operations team has a standard that states IAM policies should not be applied directly to users. Some new team members have not been following this standard. The operations manager needs a way to easily identify the users with attached policies.
What should a solutions architect do to accomplish this?
A. Monitor using AWS CloudTrail.
B. Create an AWS Config rule to run daily.
C. Publish IAM user changes to Amazon SNS.
D. Run AWS Lambda when a user is modified.
Question 184
A company wants to use an AWS Region as a disaster recovery __cpLocation for its on-premises infrastructure. The company has 10 TB of existing data, and the on- premise data center has a 1 Gbps internet connection.
A solutions architect must find a solution so the company can have its existing data on AWS in 72 hours without transmitting it using an unencrypted channel.
Which solution should the solutions architect select?
A. Send the initial 10 TB of data to AWS using FTP.
B. Send the initial 10 TB of data to AWS using AWS Snowball.
C. Establish a VPN connection between Amazon VPC and the company's data center.
D. Establish an AWS Direct Connect connection between Amazon VPC and the company's data center.
Question 185
A company is building applications in containers. The company wants to migrate its on-premises development and operations services from its on-premises data center to AWS. Management states that production systems must be cloud agnostic and use the same configuration and administrator tools across production systems. A solutions architect needs to design a managed solution that will align open-source software.
Which solution meets these requirements?
A. Launch the containers on Amazon EC2 with EC2 instance worker nodes.
B. Launch the containers on Amazon Elastic Kubernetes Service (Amazon EKS) and EKS worker nodes.
C. Launch the containers on Amazon Elastic Containers service (Amazon ECS) with AWS Fargate instances.
D. Launch the containers on Amazon Elastic Container Service (Amazon ECS) with Amazon EC2 instance worker nodes.
Question 186
A company hosts its website on AWS. To address the highly variable demand, the company has implemented Amazon EC2 Auto Scaling. Management is concerned that the company is over-provisioning its infrastructure, especially at the front end of the three-tier application. A solutions architect needs to ensure costs are optimized without impacting performance.
What should the solutions architect do to accomplish this?
A. Use Auto Scaling with Reserved Instances.
B. Use Auto Scaling with a scheduled scaling policy.
C. Use Auto Scaling with the suspend-resume feature.
D. Use Auto Scaling with a target tracking scaling policy.
Question 187
A solutions architect is performing a security review of a recently migrated workload. The workload is a web application that consists of Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer. The solutions architect must improve the security posture and minimize the impact of a DDoS attack on resources.
Which solution is MOST effective?
A. Configure an AWS WAF ACL with rate-based rules. Create an Amazon CloudFront distribution that points to the Application Load Balancer. Enable the WAF ACL on the CloudFront distribution.
B. Create a custom AWS Lambda function that adds identified attacks into a common vulnerability pool to capture a potential DDoS attack. Use the identified information to modify a network ACL to block access.
C. Enable VPC Flow Logs and store then in Amazon S3. Create a custom AWS Lambda functions that parses the logs looking for a DDoS attack. Modify a network ACL to block identified source IP addresses.
D. Enable Amazon GuardDuty and configure findings written to Amazon CloudWatch. Create an event with CloudWatch Events for DDoS alerts that triggers Amazon Simple Notification Service (Amazon SNS). Have Amazon SNS invoke a custom AWS Lambda function that parses the logs, looking for a DDoS attack. Modify a network ACL to block identified source IP addresses.
Question 188
A company has multiple AWS accounts for various departments. One of the departments wants to share an Amazon S3 bucket with all other department.
Which solution will require the LEAST amount of effort?
A. Enable cross-account S3 replication for the bucket.
B. Create a pre-signed URL for the bucket and share it with other departments.
C. Set the S3 bucket policy to allow cross-account access to other departments.
D. Create IAM users for each of the departments and configure a read-only IAM policy.
Question 189
A company needs to share an Amazon S3 bucket with an external vendor. The bucket owner must be able to access all objects.
Which action should be taken to share the S3 bucket?
A. Update the bucket to be a Requester Pays bucket.
B. Update the bucket to enable cross-origin resource sharing (CORS).
C. Create a bucket policy to require users to grant bucket-owner-full-control when uploading objects.
D. Create an IAM policy to require users to grant bucket-owner-full-control when uploading objects.
Question 190
A company is developing a real-time multiplier game that uses UDP for communications between client and servers in an Auto Scaling group. Spikes in demand are anticipated during the day, so the game server platform must adapt accordingly. Developers want to store gamer scores and other non-relational data in a database solution that will scale without intervention.
Which solution should a solutions architect recommend?
A. Use Amazon Route 53 for traffic distribution and Amazon Aurora Serverless for data storage.
B. Use a Network Load Balancer for traffic distribution and Amazon DynamoDB on-demand for data storage.
C. Use a Network Load Balancer for traffic distribution and Amazon Aurora Global Database for data storage.
D. Use an Application Load Balancer for traffic distribution and Amazon DynamoDB global tables for data storage.
