Topic 1: Exam Pool A
A company hosts its web applications in the AWS Cloud. The company configures Elastic Load Balancers to use certificate that are imported into AWS Certificate Manager (ACM). The company’s security team must be notified 30 days before the expiration of each certificate.
What should a solutions architect recommend to meet the requirement?
A. Add a rule m ACM to publish a custom message to an Amazon Simple Notification Service (Amazon SNS) topic every day beginning 30 days before any certificate will expire.
B. Create an AWS Config rule that checks for certificates that will expire within 30 days. Configure Amazon EventBridge (Amazon CloudWatch Events) to invoke a custom alert by way of Amazon Simple Notification Service (Amazon SNS) when AWS Config reports a noncompliant resource
C. Use AWS trusted Advisor to check for certificates that will expire within to days. Create an Amazon CloudWatch alarm that is based on Trusted Advisor metrics for check status changes Configure the alarm to send a custom alert by way of Amazon Simple rectification Service (Amazon SNS)
D. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to detect any certificates that will expire within 30 days. Configure the rule to invoke an AWS Lambda function. Configure the Lambda function to send a custom alert by way of Amazon Simple Notification Service (Amazon SNS).
A solutions architect needs to design a highly available application consisting of web, application, and database tiers. HTTPS content delivery should be as close to the edge as possible, with the least delivery time. Which solution meets these requirements and is MOST secure?
A. Configure a public Application Load Balancer (ALB) with multiple redundant Amazon EC2 instances in public subnets. Configure Amazon CloudFront to deliver HTTPS content using the public ALB as the origin.
B. Configure a public Application Load Balancer with multiple redundant Amazon EC2 instances in private subnets. Configure Amazon CloudFront to deliver HTTPS content using the EC2 instances as the origin.
C. Configure a public Application Load Balancer (ALB) with multiple redundant Amazon EC2 instances in private subnets. Configure Amazon CloudFront to deliver HTTPS content using the public ALB as the origin.
D. Configure a public Application Load Balancer with multiple redundant Amazon EC2 instances in public subnets. Configure Amazon CloudFront to deliver HTTPS content using the EC2 instances as the origin.
Explanation: This solution meets the requirements for a highly available application with web, application, and database tiers, as well as providing edge-based content delivery. Additionally, it maximizes security by having the ALB in a private subnet, which limits direct access to the web servers, while still being able to serve traffic over the Internet via the public ALThis will ensure that the web servers are not exposed to the public Internet, which reduces the attack surface and provides a secure way to access the application.
A company is migrating applications to AWS. The applications are deployed in different accounts. The company manages the accounts centrally by using AWS Organizations. The company's security team needs a single sign-on (SSO) solution across all the company's accounts. The company must continue managing the users and groups in its on-premises self-managed Microsoft Active Directory.
Which solution will meet these requirements?
A. Enable AWS Single Sign-On (AWS SSO) from the AWS SSO console. Create a one- way forest trust or a one-way domain trust to connect the company's self-managed Microsoft Active Directory with AWS SSO by using AWS Directory Service for Microsoft Active Directory.
B. Enable AWS Single Sign-On (AWS SSO) from the AWS SSO console. Create a two- way forest trust to connect the company's self-managed Microsoft Active Directory with AWS SSO by using AWS Directory Service for Microsoft Active Directory.
C. Use AWS Directory Service. Create a two-way trust relationship with the company's self- managed Microsoft Active Directory.
D. Deploy an identity provider (IdP) on premises. Enable AWS Single Sign-On (AWS SSO) from the AWS SSO console.
Explanation: To provide single sign-on (SSO) across all the company's accounts while continuing to manage users and groups in its on-premises self-managed Microsoft Active Directory, the solution is to enable AWS Single Sign-On (SSO) from the AWS SSO console and create a one-way forest trust or a one-way domain trust to connect the company's self- managed Microsoft Active Directory with AWS SSO by using AWS Directory Service for Microsoft Active Directory. This solution is described in the AWS documentation
A company is designing a containerized application that will use Amazon Elastic Container Service (Amazon ECS). The application needs to access a shared file system that is highly durable and can recover data to another AWS Region with a recovery point objective (RPO) of 8 hours. The file system needs to provide a mount target in each Availability Zone within a Region. A solutions architect wants to use AWS Backup to manage the replication to another Region. Which solution will meet these requirements?
A. ‘Amazon FSx for Windows File Server with a Multi-AZ deployment
B. Amazon FSx for NetApp ONTAP with a Multi-AZ deployment
C. ‘Amazon Elastic File System (Amazon EFS) with the Standard storage class
D. Amazon FSx for OpenZFS
Explanation: This answer is correct because it meets the requirements of accessing a shared file system that is highly durable, can recover data to another AWS Region, and can provide a mount target in each Availability Zone within a Region. Amazon FSx for NetApp ONTAP is a fully managed service that provides enterprise-grade data management and storage for your Windows and Linux applications. You can use Amazon FSx for NetApp ONTAP to create file systems that span multiple Availability Zones within an AWS Region, providing high availability and durability. You can also use AWS Backup to manage the replication of your file systems to another AWS Region, with a recovery point objective (RPO) of 8 hours or less. AWS Backup is a fully managed backup service that automates and centralizes backup of data over AWS services. You can use AWS Backup to create backup policies and monitor activity for your AWS resources in one place.
A company needs the ability to analyze the log files of its proprietary application. The logs are stored in JSON format in an Amazon S3 bucket Queries will be simple and will run on- demand A solutions architect needs to perform the analysis with minimal changes to the existing architecture What should the solutions architect do to meet these requirements with the LEAST amount of operational overhead?
A. Use Amazon Redshift to load all the content into one place and run the SQL queries as needed
B. Use Amazon CloudWatch Logs to store the logs Run SQL queries as needed from the Amazon CloudWatch console
C. Use Amazon Athena directly with Amazon S3 to run the queries as needed
D. Use AWS Glue to catalog the logs Use a transient Apache Spark cluster on Amazon EMR to run the SQL queries as needed
