Amazon AWS Certified Solutions Architect - Associate (SAA-C03) 認定 AWS-Solutions-Architect-Associate 試験問題 (Q162-Q167):

質問 # 162
You must architect the migration of a web application to AWS. The application consists of Linux web servers running a custom web server. You are required to save the logs generated from the application to a durable location.
What options could you select to migrate the application to AWS? (Choose 2)

A. Create Dockerfile for the application. Create an AWS OpsWorks stack consisting of a custom layer.
Create custom recipes to install Docker and to deploy your Docker container using the Dockerfile.
Create customer recipes to install and configure the application to publish the logs to Amazon CloudWatch Logs.
B. Create an AWS Elastic Beanstalk application using the custom web server platform. Specify the web server executable and the application project and source files. Enable log file rotation to Amazon Simple Storage Service (S3).
C. Create Dockerfile for the application. Create an AWS OpsWorks stack consisting of a Docker layer that uses the Dockerfile. Create custom recipes to install and configure Amazon Kineses to publish the logs into Amazon CloudWatch.
D. Create a Dockerfile for the application. Create an AWS Elastic Beanstalk application using the Docker platform and the Dockerfile. Enable logging the Docker configuration to automatically publish the application logs. Enable log file rotation to Amazon S3.
E. Use VM import/Export to import a virtual machine image of the server into AWS as an AMI. Create an Amazon Elastic Compute Cloud (EC2) instance from AMI, and install and configure the Amazon CloudWatch Logs agent. Create a new AMI from the instance. Create an AWS Elastic Beanstalk application using the AMI platform and the new AMI.

正解：B、D

質問 # 163
A company is deploying a new application on Amazon EC2 instances. The application writes data to Amazon Elastic Block Store (Amazon EBS) volumes. The company needs to ensure that all data that is written to the EBS volumes is encrypted at rest.
Which solution will meet this requirement?

A. Create an EC2 instance tag that has a key of Encrypt and a value of True. Tag all instances that require encryption at the EBS level.
B. Create an AWS Key Management Service (AWS KMS) key policy that enforces EBS encryption in the account. Ensure that the key policy is active
C. Create the EBS volumes as encrypted volumes. Attach the EBS volumes to the EC2 instances
D. Create an IAM role that specifies EBS encryption. Attach the role to the EC2 instances.

正解：C

解説：
The solution that will meet the requirement of ensuring that all data that is written to the EBS volumes is encrypted at rest is B. Create the EBS volumes as encrypted volumes and attach the encrypted EBS volumes to the EC2 instances. When you create an EBS volume, you can specify whether to encrypt the volume. If you choose to encrypt the volume, all data written to the volume is automatically encrypted at rest using AWS- managed keys. You can also use customer-managed keys (CMKs) stored in AWS KMS to encrypt and protect your EBS volumes. You can create encrypted EBS volumes and attach them to EC2 instances to ensure that all data written to the volumes is encrypted at rest.

質問 # 164
You are the new IT architect in a company that operates a mobile sleep tracking application When activated at night, the mobile app is sending collected data points of 1 kilobyte every
5 minutes to your backend
The backend takes care of authenticating the user and writing the data points into an Amazon DynamoDB table.
Every morning, you scan the table to extract and aggregate last night's data on a per user basis, and store the results in Amazon S3.
Users are notified via Amazon SMS mobile push notifications that new data is available, which is parsed and visualized by (The mobile app Currently you have around 100k users who are mostly based out of North America.
You have been tasked to optimize the architecture of the backend system to lower cost what would you recommend? (Choose 2 answers)

A. Write data directly into an Amazon Redshift cluster replacing both Amazon DynamoDB and Amazon S3.
B. Introduce an Amazon SQS queue to buffer writes to the Amazon DynamoDB table and reduce provisioned write throughput.
C. Create a new Amazon DynamoDB (able each day and drop the one for the previous day after its data is on Amazon S3.
D. Have the mobile app access Amazon DynamoDB directly instead of JSON files stored on Amazon S3.
E. Introduce Amazon Elasticache lo cache reads from the Amazon DynamoDB table and reduce provisioned read throughput.

正解：D、E

質問 # 165
A security team wants to limit access to specific services or actions in all of the team's AWS accounts. All accounts belong to a large organization in AWS Organizations The solution must be scalable and there must be asingle point where permissions can be maintained.
What should a solutions architect do to accomplish this?

A. Create a service control policy in the root organizational unit to deny access to the services or actions
B. Create an ACL to provide access to the services or actions.
C. Create cross-account roles in each account to deny access to the services or actions.
D. Create a security group to allow accounts and attach it to user groups

正解：A

解説：
Explanation
https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_policies_scp.html.
Service Control Policy concepts
SCPs offer central access controls for all IAM entities in your accounts. You can use them to enforce the permissions you want everyone in your business to follow. Using SCPs, you can give your developers more freedom to manage their own permissions because you know they can only operate within the boundaries you define.
You create and apply SCPs through AWS Organizations. When you create an organization, AWS Organizations automatically creates a root, which forms the parent container for all the accounts in your organization. Inside the root, you can group accounts in your organization into organizational units (OUs) to simplify management of these accounts. You can create multiple OUs within a single organization, and you can create OUs within other OUs to form a hierarchical structure. You can attach SCPs to the organization root, OUs, and individual accounts. SCPs attached to the root and OUs apply to all OUs and accounts inside of them.
SCPs use the AWS Identity and Access Management (IAM) policy language; however, they do not grant permissions. SCPs enable you set permission guardrails by defining the maximum available permissions for IAM entities in an account. If a SCP denies an action for an account, none of the entities in the account can take that action, even if their IAM permissions allow them to do so. The guardrails set in SCPs apply to all IAM entities in the account, which include all users, roles, and the account root user.

質問 # 166
A company hosts an application on an Amazon EC2 instance that requires a maximum of 200 GB storage space. The application is used infrequently, with peaks during mornings and evenings. Disk I/O varies, but peaks at 3,000 IOPS. The chief financial officer of the company is concerned about costs and has asked a solutions architect to recommend the most cost-effective storage option that does not sacrifice performance.
Which solution should the solutions architect recommend?

A. Amazon EBS Cold HDD (sc1)
B. Amazon EBS Throughput Optimized HDD (st1)
C. Amazon EBS Provisioned IOPS SSD (io1)
D. Amazon EBS General Purpose SSD (gp2)

正解：D
