질문 # 83
You are designing a photo-sharing mobile app. The application will store all pictures in a single Amazon
S3 bucket. Users will upload pictures from their mobile device directly to Amazon S3 and will be able to
view and download their own pictures directly from Amazon S3.
You want to configure security to handle potentially millions of users in the most secure manner possible.
What should your server-side application do when a new user registers on the photo-sharing mobile
application?

A. Create an IAM user. Update the bucket policy with appropriate permissions for the IAM user.
Generate an access key and secret key for the IAM user, store them in the mobile app and use these
credentials to access Amazon S3.
B. Create a set of long-term credentials using AWS Security Token Service with appropriate permissions.
Store these credentials in the mobile app and use them to access Amazon S3.
C. Record the user's information in Amazon RDS and create a role in IAM with appropriate permissions.
When the user uses their mobile app, create temporary credentials using the AWS Security Token
Service "AssumeRole" function. Store these credentials in the mobile app's memory and use them to
access Amazon S3. Generate new credentials the next time the user runs the mobile app.
D. Record the user's information in Amazon DynamoDB. When the user uses their mobile app, create
temporary credentials using AWS Security Token Service with appropriate permissions. Store these
credentials in the mobile app's memory and use them to access Amazon S3. Generate new credentials
the next time the user runs the mobile app.
E. Create an IAM user. Assign appropriate permissions to the IAM user. Generate an access key and
secret key for the IAM user, store them in the mobile app and use these credentials to access Amazon
S3.

정답：C

질문 # 84
The company Security team requires that all data uploaded into an Amazon S3 bucket must be encrypted. The encryption keys must be highly available and the company must be able to control access on a per-user basis, with different users having access to different encryption keys.
Which of the following architectures will meet these requirements? (Choose two.)

A. Use Amazon S3 server-side encryption with customer-managed keys, and use AWS CloudHSM to manage the keys. Use CloudHSM client software to control access to the keys that are generated.
B. Use Amazon S3 server-side encryption with customer-managed keys, and use two AWS CloudHSM instances configured in high-availability mode to manage the keys. Use IAM to control access to the keys that are generated in CloudHSM.
C. Use Amazon S3 server-side encryption with AWS KMS-managed keys, create multiple customer master keys, and use key policies to control access to them.
D. Use Amazon S3 server-side encryption with customer-managed keys, and use two AWS CloudHSM instances configured in high-availability mode to manage the keys. Use the Cloud HSM client software to control access to the keys that are generated.
E. Use Amazon S3 server-side encryption with Amazon S3-managed keys. Allow Amazon S3 to generate an AWS/S3 master key, and use IAM to control access to the data keys that are generated.

질문 # 85
A company built an application based on AWS Lambda deployed in an AWS CloudFormation stack. The last production release of the web application introduced an issue that resulted in an outage lasting several minutes.
A solutions architect must adjust the deployment process to support a canary release.
Which solution will meet these requirements?

A. Create an alias for every new deployed version of the Lambda function. Use the AWS CLI update-alias command with the routing-config parameter to distribute the load.
B. Create a version for every new deployed Lambda function. Use the AWS CLI update-function-configuration command with the routing-config parameter to distribute the load.
C. Configure AWS CodeDeploy and use CodeDeployDefault.OneAtATime in the Deployment configuration to distribute the load.
D. Deploy the application into a new CloudFormation stack. Use an Amazon Route 53 weighted routing policy to distribute the load.

정답：A

질문 # 86
An on-premises application will be migrated to the cloud. The application consists of a single Elasticsearch virtual machine with data source feeds from local systems that will not be migrated, and a Java web application on Apache Tomcat running on three virtual machines. The Elasticsearch server currently uses 1 TB of storage out of 16 TB available storage, and the web application is updated every 4 months. Multiple users access the web application from the Internet. There is a 10Gbit AWS Direct Connect connection established, and the application can be migrated over a schedules 48-hour change window.
Which strategy will have the LEAST impact on the Operations staff after the migration?

A. Use the AWS SMS to replicate the virtual machines into AWS. When the migration is complete, pause the data source feeds and start the migrated Elasticsearch and web application instances.
Place the web application instances behind a public Elastic Load Balancer. Move the data source feeds to the new Elasticsearch server and move users to the new web Application Load Balancer.
B. Create an Amazon ES cluster for Elasticsearch and a public AWS Elastic Beanstalk environment for the web application. Pause the data source feeds, export the Elasticsearch index from on premises, and import into the Amazon ES cluster. Move the data source feeds to the new Amazon ES cluster endpoint and move users to the new web application.
C. Create an Elasticsearch server on Amazon EC2 right-sized with 2 TB of Amazon EBS and a public AWS Elastic Beanstalk environment for the web application. Pause the data sources, export the Elasticsearch index from on premises, and import into the EC2 Elasticsearch server.
Move data source feeds to the new Elasticsearch server and move users to the web application.
D. Create an Amazon ES cluster for Elasticsearch and a public AWS Elastic Beanstalk environment for the web application. Use AWS DMS to replicate Elasticsearch data. When replication has finished, move data source feeds to the new Amazon ES cluster endpoint and move users to the new web application.

정답：D

설명：
A: uses EC2s, and that requires maintenance after the migration. contradicting with least operation after migration.
C: Good, but again uses self Elastic Search and EC2s, which requires operation maintenance staff after migration.
D: the sequence of moving the index to ES is wrong. They should have replicate then pause!
However, answer "B" uses DMS as a replication tool.

질문 # 87
An ecommerce website running on AWS uses an Amazon RDS for MySQL DB instance with General Purpose SSD storage. The developers chose an appropriate instance type based on demand, and configured 100 GB of storage with a sufficient amount of free space.
The website was running smoothly for a few weeks until a marketing campaign launched On the second day of the campaign, users reported long wait times and time outs Amazon CloudWatch metrics indicated that both reads and writes to the DB instance were experiencing long response times. The CloudWatch metrics show 40% to 50% CPU and memory utilization, and sufficient free storage space is still available The application server logs show no evidence of database connectivity issues What could be the root cause of the issue with the marketing campaign?

A. It exhausted the I/O credit balance due to provisioning low disk storage during the setup phase
B. It exhausted the maximum number of allowed connections to the database instance
C. It exhausted the network bandwidth available to the RDS for MySQL DB instance
D. It caused the data in the tables to change frequently, requiring indexes to be rebuilt to optimize queries
