1. Question 81 · 1017 in bank

   A company sells ringtones created from clips of popular songs. The files containing the ringtones are stored in Amazon S3 Standard and are at least 128 KB in size. The company has millions of files, but downloads are infrequent for ringtones older than 90 days. The company needs to save money on storage while keeping the most accessed files readily available for its users. Which action should the company take to meet these requirements MOST cost-effectively?

   • AConfigure S3 Standard-Infrequent Access (S3 Standard-IA) storage for the initial storage tier of the objects.
   • BMove the files to S3 Intelligent-Tiering and configure it to move objects to a less expensive storage tier after 90 days.
   • CConfigure S3 inventory to manage objects and move them to S3 Standard-Infrequent Access (S3 Standard-1A) after 90 days.
   • DImplement an S3 Lifecycle policy that moves the objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-1A) after 90 days.

   Show answer

   Answer: D

   Explanation

   Answer D Why Optoin D ? The Question talks about downloads are infrequent older than 90 days which means files less than 90 days are accessed frequently. Standard-Infrequent Access (S3 Standard-IA) needs a minimum 30 days if accessed before, it costs more. So to access the files frequently you need a S3 Standard . After 90 days you can move it to Standard-Infrequent Access (S3 Standard-IA) as its going to be less frequently accessed

2. Question 82 · 1017 in bank

   A company needs to save the results from a medical trial to an Amazon S3 repository. The repository must allow a few scientists to add new files and must restrict all other users to read-only access. No users can have the ability to modify or delete any files in the repository. The company must keep every file in the repository for a minimum of 1 year after its creation date. Which solution will meet these requirements?

   • AUse S3 Object Lock in governance mode with a legal hold of 1 year.
   • BUse S3 Object Lock in compliance mode with a retention period of 365 days.
   • CUse an IAM role to restrict all users from deleting or changing objects in the S3 bucket. Use an S3 bucket policy to only allow the IAM role.
   • DConfigure the S3 bucket to invoke an AWS Lambda function every time an object is added. Configure the function to track the hash of the saved object so that modified objects can be marked accordingly.

   Show answer

   Answer: B

   Explanation

   B, The key is "No users can have the ability to modify or delete any files" and compliance mode supports that. I remember it this way: ( governance is like government, they set the rules but they can allow some people to break it :D )

3. Question 83 · 1017 in bank

   A large media company hosts a web application on AWS. The company wants to start caching confidential media files so that users around the world will have reliable access to the files. The content is stored in Amazon S3 buckets. The company must deliver the content quickly, regardless of where the requests originate geographically. Which solution will meet these requirements?

   • AUse AWS DataSync to connect the S3 buckets to the web application.
   • BDeploy AWS Global Accelerator to connect the S3 buckets to the web application.
   • CDeploy Amazon CloudFront to connect the S3 buckets to CloudFront edge servers.
   • DUse Amazon Simple Queue Service (Amazon SQS) to connect the S3 buckets to the web application.

   Show answer

   Answer: C

   Explanation

   The reasons are: Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations around the world. Connecting the S3 buckets containing the media files to CloudFront will cache the content at global edge locations. This provides fast reliable access to users everywhere by serving content from the nearest edge location. CloudFront integrates tightly with S3 for secure, durable storage. Global Accelerator improves availability and performance for TCP/UDP traffic, not HTTP-based content delivery. DataSync and SQS are not technologies for a global CDN like CloudFront.

   A company produces batch data that comes from different databases. The company also produces live stream data from network sensors and application APIs. The company needs to consolidate all the data into one place for business analytics. The company needs to process the incoming data and then stage the data in different Amazon S3 buckets. Teams will later run one-time queries and import the data into a business intelligence tool to show key performance indicators (KPIs). Which combination of steps will meet these requirements with the LEAST operational overhead? (Choose two.)

   • AUse Amazon Athena for one-time queries. Use Amazon QuickSight to create dashboards for KPIs.
   • BUse Amazon Kinesis Data Analytics for one-time queries. Use Amazon QuickSight to create dashboards for KPIs.
   • CCreate custom AWS Lambda functions to move the individual records from the databases to an Amazon Redshift cluster.
   • DUse an AWS Glue extract, transform, and load (ETL) job to convert the data into JSON format. Load the data into multiple Amazon OpenSearch Service (Amazon Elasticsearch Service) clusters.
   • EUse blueprints in AWS Lake Formation to identify the data that can be ingested into a data lake. Use AWS Glue to crawl the source, extract the data, and load the data into Amazon S3 in Apache Parquet format.

   Show answer

   Answer: AE

   Explanation

   The reasons are: AWS Lake Formation and Glue provide automated data lake creation with minimal coding. Glue crawlers identify sources and ETL jobs load to S3. Athena allows ad-hoc queries directly on S3 data with no infrastructure to manage. QuickSight provides easy cloud BI for dashboards. Options C and D require significant custom coding for ETL and queries. Redshift and OpenSearch would require additional setup and management overhead.

   • BCreate a lifecycle policy for the automated backups.
   • CConfigure automated backup retention for 5 years.
   • DConfigure an Amazon CloudWatch Logs export for the DB cluster.
   • EUse AWS Backup to take the backups and to keep the backups for 5 years.

   Show answer

   Answer: DE

   Explanation

   I tend to agree D and E... A - Manual task that can be automated, so why make life difficult? B - The maximum retention period is 35 days, so would not help C - The maximum retention period is 35 days, so would not help D - Only option that deals with logs, so makes sense E - Partially manual but only option that achieves the 5 year goal

   A company is running a publicly accessible serverless application that uses Amazon API Gateway and AWS Lambda. The application’s traffic recently spiked due to fraudulent requests from botnets. Which steps should a solutions architect take to block requests from unauthorized users? (Choose two.)

   • ACreate a usage plan with an API key that is shared with genuine users only.
   • BIntegrate logic within the Lambda function to ignore the requests from fraudulent IP addresses.
   • CImplement an AWS WAF rule to target malicious requests and trigger actions to filter them out.
   • DConvert the existing public API to a private API. Update the DNS records to redirect users to the new API endpoint.
   • ECreate an IAM role for each user attempting to access the API. A user will assume the role when making the API call.

   Show answer

   Answer: AC

   Explanation

   Only answer C is an obviouis choice. B and D are clearly not right and A is the only remotely viable other answer but even then the documentation on API Keys and Usage quotas states not to rely on it to block API requests; Usage plan throttling and quotas are not hard limits, and are applied on a best-effort basis. In some cases, clients can exceed the quotas that you set. Don’t rely on usage plan quotas or throttling to control costs or block access to an API. Consider using AWS Budgets to monitor costs and AWS WAF to manage API requests. https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-api-usage-plans.html

10. Question 90 · 1017 in bank

    A company has a small Python application that processes JSON documents and outputs the results to an on-premises SQL database. The application runs thousands of times each day. The company wants to move the application to the AWS Cloud. The company needs a highly available solution that maximizes scalability and minimizes operational overhead. Which solution will meet these requirements?

    • APlace the JSON documents in an Amazon S3 bucket. Run the Python code on multiple Amazon EC2 instances to process the documents. Store the results in an Amazon Aurora DB cluster.
    • BPlace the JSON documents in an Amazon S3 bucket. Create an AWS Lambda function that runs the Python code to process the documents as they arrive in the S3 bucket. Store the results in an Amazon Aurora DB cluster.
    • CPlace the JSON documents in an Amazon Elastic Block Store (Amazon EBS) volume. Use the EBS Multi-Attach feature to attach the volume to multiple Amazon EC2 instances. Run the Python code on the EC2 instances to process the documents. Store the results on an Amazon RDS DB instance.
    • DPlace the JSON documents in an Amazon Simple Queue Service (Amazon SQS) queue as messages. Deploy the Python code as a container on an Amazon Elastic Container Service (Amazon ECS) cluster that is configured with the Amazon EC2 launch type. Use the container to process the SQS messages. Store the results on an Amazon RDS DB instance.

    Show answer

    Answer: B

    Explanation

    By placing the JSON documents in an S3 bucket, the documents will be stored in a highly durable and scalable object storage service. The use of AWS Lambda allows the company to run their Python code to process the documents as they arrive in the S3 bucket without having to worry about the underlying infrastructure. This also allows for horizontal scalability, as AWS Lambda will automatically scale the number of instances of the function based on the incoming rate of requests. The results can be stored in an Amazon Aurora DB cluster, which is a fully-managed, high-performance database service that is compatible with MySQL and PostgreSQL. This will provide the necessary durability and scalability for the results of the processing.
