PDF with 424 Questions

A development team recently deployed a new version of a web application to production. After the release, penetration testing revealed a cross-site scripting vulnerability that could expose user data.
Which AWS service will mitigate this issue?

  1. AWS Shield Standard
  2. AWS WAF
  3. Elastic Load Balancing
  4. Amazon Cognito

Answer(s): B



A SysOps administrator must configure a resilient tier of Amazon EC2 instances for a high performance computing (HPC) application. The HPC application requires minimum latency between nodes.
Which actions should the SysOps administrator take to meet these requirements? (Choose two.)

  1. Create an Amazon Elastic File System (Amazon EFS) file system. Mount the file system to the EC2 instances by using user data.
  2. Create a Multi-AZ Network Load Balancer in front of the EC2 instances.
  3. Place the EC2 instances in an Auto Scaling group within a single subnet.
  4. Launch the EC2 instances into a cluster placement group.
  5. Launch the EC2 instances into a partition placement group.

Answer(s): C,D



A company’s customers are reporting increased latency while accessing static web content from Amazon S3. A SysOps administrator observed a very high rate of read operations on a particular S3 bucket.
What will minimize latency by reducing load on the S3 bucket?

  1. Migrate the S3 bucket to a region that is closer to end users’ geographic locations.
  2. Use cross-region replication to replicate all of the data to another region.
  3. Create an Amazon CloudFront distribution with the S3 bucket as the origin.
  4. Use Amazon ElastiCache to cache data being served from Amazon S3.

Answer(s): C



A SysOps administrator needs to develop a solution that provides email notification and inserts a record into a database every time a file is put into an Amazon S3 bucket.
What is the MOST operationally efficient solution that meets these requirements?

  1. Set up an S3 event notification that targets an Amazon Simple Notification Service (Amazon SNS) topic. Create two subscriptions for the SNS topic. Use one subscription to send the email notification. Use the other subscription to invoke an AWS Lambda function that inserts the record into the database.
  2. Set up an Amazon CloudWatch alarm that enters ALARM state whenever an object is created in the S3 bucket. Configure the alarm to invoke an AWS Lambda function that sends the email notification and inserts the record into the database.
  3. Create an AWS Lambda function to send the email notification and insert the record into the database whenever a new object is detected in the S3 bucket. Invoke the function every minute with an Amazon EventBridge (Amazon CloudWatch Events) scheduled rule.
  4. Set up two S3 event notifications. Target a separate AWS Lambda function with each notification. Configure one function to send the email notification. Configure the other function to insert the record into the database.

Answer(s): A



A company hosts a web application on Amazon EC2 instances behind an Application Load Balancer. The instances are in an Amazon EC2 Auto Scaling group. The application is accessed with a public URL.
A SysOps administrator needs to implement a monitoring solution that checks the availability of the application and follows the same routes and actions as a customer. The SysOps administrator must receive a notification if less than 95% of the monitoring runs find no errors.
Which solution will meet these requirements?

  1. Create an Amazon CloudWatch Synthetics canary with a script that follows customer routes. Schedule the canary to run on a recurring schedule. Create a CloudWatch alarm that publishes a message to an Amazon Simple Notification Service (Amazon SNS) topic when the SuccessPercent metric is less than 95%.
  2. Create Amazon Route 53 health checks that monitor the availability of the endpoint. Create Amazon CloudWatch alarms that publish a message to an Amazon Simple Notification Service (Amazon SNS) topic when the HealthCheckPercentageHealthy metric is less than 95%.
  3. Create a single AWS Lambda function to check whether the endpoints are available for each customer path. Schedule the Lambda function by using Amazon EventBridge (Amazon CloudWatch Events). Configure the Lambda function to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic when an endpoint returns an error.
  4. Create an AWS Lambda function for each customer path to check whether that specific endpoint is available. Schedule the Lambda functions by using Amazon EventBridge (Amazon CloudWatch Events). Configure each Lambda function to publish a custom metric to Amazon CloudWatch for the endpoint status. Create CloudWatch alarms based on each custom metric to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic when an alarm is in the ALARM state.

Answer(s): A
