A solutions architect is designing a highly available Amazon ElastiCache for Redis based solution. The solutions architect needs to ensure that failures do not result in performance degradation or loss of data locally and within an AWS Region. The solution needs to provide high availability at the node level and at the Region level.
Which solution will meet these requirements?
A. Use Redis shards that contain multiple nodes with Auto Scaling turned on.
B. Use a Multi-AZ Redis cluster with more than one read replica in the replication group.
C. Use Redis shards that contain multiple nodes with Redis append only files (AOF) tured on.
D. Use Multi-AZ Redis replication groups with shards that contain multiple nodes.
正解：D
解説：
This answer is correct because it provides high availability at the node level and at the Region level for the ElastiCache for Redis solution. A Multi-AZ Redis replication group consists of a primary cluster and up to five read replica clusters, each in a different Availability Zone. If the primary cluster fails, one of the read replicas is automatically promoted to be the new primary cluster. A Redis replication group with shards enables partitioning of the data across multiple nodes, which increases the scalability and performance of the solution. Each shard can have one or more replicas to provide redundancy and read scaling.

A company wants to migrate its on-premises data center to AWS. According to the company's compliance requirements, the company can use only the ap-northeast-3 Region. Company administrators are not permitted to connect VPCs to the internet.
Which solutions will meet these requirements? (Choose two.)
A. Use rules in AWS WAF to prevent internet access. Deny access to all AWS Regions except ap-northeast-3 in the AWS account settings.
B. Use AWS Control Tower to implement data residency guardrails to deny internet access and deny access to all AWS Regions except ap-northeast-3.
C. Use AWS Config to activate managed rules to detect and alert for internet gateways and to detect and alert for new resources deployed outside of ap-northeast-3.
D. Use AWS Organizations to configure service control policies (SCPS) that prevent VPCs from gaining internet access. Deny access to all AWS Regions except ap-northeast-3.
E. Create an outbound rule for the network ACL in each VPC to deny all traffic from 0.0.0.0/0. Create an
1AM policy for each user to prevent the use of any AWS Region other than ap-northeast-3.
正解：B、D
質問 # 35
A company wants to relocate its on-premises MySQL database to AWS. The database accepts regular imports from a client-facing application, which causes a high volume of write operations. The company is concerned that the amount of traffic might be causing performance issues within the application.
A. Provision an Amazon DocumentDB (with MongoDB compatibility) instance with a memory-optimized instance type. Monitor Amazon CloudWatch for performance-related issues. Change the instance class if necessary.
B. Provision an Amazon Elastic File System (Amazon EFS) file system in General Purpose performance mode. Monitor Amazon CloudWatch for IOPS bottlenecks. Change to Provisioned Throughput performance mode if necessary.
C. Provision an Amazon RDS for MySQL DB instance with General Purpose SSD storage. Place an Amazon ElastiCache cluster in front of the DB instance. Configure the application to query ElastiCache instead.
D. Provision an Amazon RDS for MySQL DB instance with Provisioned IOPS SSD storage. Monitor write operation metrics by using Amazon CloudWatch. Adjust the provisioned IOPS if necessary.
正解：D
解説：
Comprehensive and Detailed Explanation:
For a MySQL database experiencing high write operations, using Amazon RDS with Provisioned IOPS (io1 or io2) SSD storage is recommended to achieve consistent and low-latency performance. Provisioned IOPS allows you to specify a desired IOPS rate, which is crucial for write-intensive workloads.
Monitoring write operation metrics through Amazon CloudWatch enables you to observe performance and adjust the provisioned IOPS as needed to meet application demands.

質問 # 36
A company hosts a public web application on AWS. The website has a three-tier architecture. The frontend web tier is comprised of Amazon EC2 instances in an Auto Scaling group. The application tier is a second Auto Scaling group. The database tier is an Amazon RDS database.
The company has configured the Auto Scaling groups to handle the application's normal level of demand. During an unexpected spike in demand, the company notices a long delay in the startup time when the frontend and application layers scale out. The company needs to improve the scaling performance of the application without negatively affecting the user experience.
Which solution will meet these requirements MOST cost-effectively?
A. Configure the maximum number of instances for both Auto Scaling groups to be the number required to meet the peak demand. Create a warm pool.
B. Reconfigure both Auto Scaling groups to use a scheduled scaling policy. Increase the size of the EC2 instance types and the RDS instance types.
C. Increase the maximum number of EC2 instances for both Auto Scaling groups to meet the normal demand requirement. Create a warm pool.
D. Decrease the minimum number of EC2 instances for both Auto Scaling groups. Increase the desired number of instances to meet the peak demand requirement.
正解：A
解説：
EC2 Auto Scaling warm pools allow you to pre-initialize instances, reducing the delay in scale-out events. This results in significantly faster response times during demand surges while remaining cost-effective compared to always running at peak capacity.

質問 # 37
A company needs a solution to automate email ingestion. The company needs to automatically parse email messages, look for email attachments, and save any attachments to an Amazon S3 bucket in near real time. Email volume varies significantly from day to day.
Which solution will meet these requirements?
A. Set up email receiving in Amazon Simple Email Service (Amazon SES). Configure Amazon SES and S3 Event Notifications to process the email bodies and attachments.
B. Create an AWS Lambda function to process the email bodies and attachments. Use Amazon EventBridge to invoke the Lambda function. Configure an EventBridge rule to listen for incoming emails.
C. Set up email content filtering in Amazon Simple Email Service (Amazon SES). Create a content filtering rule based on sender, recipient, message body, and attachments.
D. Set up email receiving in Amazon Simple Email Service {Amazon SES). Create a rule set and a receipt rule. Create an AWS Lambda function that Amazon SES can invoke to process the email bodies and attachments.
正解：D
解説：
AmazonSES (Simple Email Service)allows for the automatic ingestion of incoming emails. By setting up email receiving in SES and creating a rule set with a receipt rule, you can configure SES to invoke anAWS Lambda functionwhenever an email is received. The Lambda function can then process the email body and attachments, saving any attachments to an Amazon S3 bucket. This solution is highly scalable, cost-effective, and provides near real-time processing of emails with minimal operational overhead.
Option B (Content filtering): This only filters emails based on content and does not provide the functionality to save attachments to S3.
Option C (S3 Event Notifications): While SES can store emails in S3, SES with Lambda offers more flexibility for processing attachments in real-time.
Option D (EventBridge rule): EventBridge cannot directly listen for incoming emails, making this solution incorrect.
