• Question 154:

  A SysOps administrator is responsible for more than 50 Amazon EC2 instances that are deployed in a single production AWS account. The EC2 instances are running several different operating systems. The company's standards require patching to be completed at least once a month.

  The SysOps administrator wants to use AWS Systems Manager to reduce the number of hours the company spends on operating system patching each month.

  Which combination of steps should the SysOps administrator take to meet these requirements? (Choose three.)

  A. Group similar EC2 instances together into resource groups by using AWS Resource Groups.
  B. Create a schedule in Systems Manager Patch Manager. Specify the appropriate resource group as the target.
  C. Specify Systems Manager Automation runbooks to patch the operating systems. Register the runbooks as tasks in the maintenance window. Specify the appropriate resource group as the target.
  D. Create a Systems Manager Automation runbook to monitor and control the state of the patches required. Apply the runbook to Systems Manager Patch Manager.

• Question 155:

  A company is supposed to receive a data file every hour in an Amazon S3 bucket. An S3 event notification invokes an AWS Lambda function each time a file arrives. The function processes the data for use by an application. The application

  team notices that sometimes the file does not arrive. The application team wants to receive a notification whenever the file does not arrive.

  What is the MOST operationally efficient solution that meets these requirements?

  A. Add an S3 Lifecycle rule on the S3 bucket with a scope that is limited to objects that were created in the last hour. Configure another S3 event notification to be invoked by the lifecycle transition when the number of objects transitioned is zero. Publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to notify the application team.
  B. Configure another S3 event notification to invoke a Lambda function that posts a message to an Amazon Simple Queue Service (Amazon SQS) queue. Create an Amazon CloudWatch alarm to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to notify the application team when the ApproximateAgeOfOldestMessage metric of the queue is greater than 1 hour.
  C. Create an Amazon CloudWatch alarm to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to alert the application team when the Invocations metric of the Lambda function is zero for an hour. Configure the alarm to treat missing data as breaching.
  D. Create a new Lambda function to get the timestamp of the newest file in the S3 bucket. If the timestamp is more than 1 hour ago, publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to notify the application team. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke the new function hourly.
  C. Create an Amazon CloudWatch alarm to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to alert the application team when the Invocations metric of the Lambda function is zero for an hour. Configure the alarm to treat missing data as breaching.

• Question 156:

  A company plans to migrate several of its high performance computing (MPC) virtual machines (VMs) to Amazon EC2 instances on AWS. A SysOps administrator must identify a placement group for this deployment. The strategy must minimize network latency and must maximize network throughput between the HPC VMs.

  Which strategy should the SysOps administrator choose to meet these requirements?

  A. Deploy the instances in a cluster placement group in one Availability Zone.
  B. Deploy the instances in a partition placement group in two Availability Zones
  C. Deploy the instances in a partition placement group in one Availability Zone
  D. Deploy the instances in a spread placement group in two Availably Zones
  A. Deploy the instances in a cluster placement group in one Availability Zone.

• Question 157:

  A company has two general purpose Amazon EC2 instances that run a software package.

  Each EC2 instance is attached to its own 500 GiB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volume.

  Each EBS volume frequently reaches its IOPS limit, negatively affecting workload performance. The company is starting a large promotion that will require 5 times more IOPS.

  Which solution will meet these requirements?

  A. Migrate the attached EBS volumes to Throughput Optimized HDD (st1) EBS volumes.
  B. Configure Amazon ElastiCache integration on the EC2 instances.
  C. Migrate the workload to two storage optimized EC2 instances.
  D. Migrate the attached EBS volumes to General Purpose SSD (gp3) EBS volumes. Provision the appropriate IOPS.
  D. Migrate the attached EBS volumes to General Purpose SSD (gp3) EBS volumes. Provision the appropriate IOPS.

• Question 158:

  A company has created a NAT gateway in a public subnet in a VPC. The VPC also contains a private subnet that includes Amazon EC2 instances. The EC2 instances use the NAT gateway to access the internet to download patches and updates. The company has configured a VPC flow log for the elastic network interface of the NAT gateway. The company is publishing the output to Amazon CloudWatch Logs.

  A SysOps administrator must identify the top five internet destinations that the EC2 instances in the private subnet communicate with for downloads.

  What should the SysOps administrator do to meet this requirement in the MOST operationally efficient way?

  A. Use AWS CloudTrail Insights events to identify the top five internet destinations.
  B. Use Amazon CloudFront standard logs (access logs) to identify the top five internet destinations.
  C. Use CloudWatch Logs Insights to identify the top five internet destinations.
  D. Change the flow log to publish logs to Amazon S3. Use Amazon Athena to query the log files in Amazon S3.
  C. Use CloudWatch Logs Insights to identify the top five internet destinations.

• Question 159:

  A company website contains a web tier and a database tier on AWS. The web tier consists of Amazon EC2 instances that run in an Auto Scaling group across two Availability Zones. The database tier runs on an Amazon ROS for MySQL Multi-AZ DB instance. The database subnet network ACLs are restricted to only the web subnets that need access to the database. The web subnets use the default network ACL with the default rules.

  The company's operations team has added a third subnet to the Auto Scaling group configuration. After an Auto Scaling event occurs, some users report that they intermittently receive an error message. The error message states that the server cannot connect to the database. The operations team has confirmed that the route tables are correct and that the required ports are open on all security groups.

  Which combination of actions should a SysOps administrator take so that the web servers can communicate with the DB instance? (Select TWO.)

  A. On the default ACL. create inbound Allow rules of type TCP with the ephemeral port range and the source as the database subnets.
  B. On the default ACL, create outbound Allow rules of type MySQL/Aurora (3306). Specify the destinations as the database subnets.
  C. On the network ACLs for the database subnets, create an inbound Allow rule of type MySQL/Aurora (3306). Specify the source as the third web subnet.
  D. On the network ACLs for the database subnets, create an outbound Allow rule of type TCP with the ephemeral port range and the destination as the third web subnet.
  E. On the network ACLs for the database subnets, create an outbound Allow rule of type MySQL/Aurora (3306). Specify the destination as the third web subnet.
  C. On the network ACLs for the database subnets, create an inbound Allow rule of type MySQL/Aurora (3306). Specify the source as the third web subnet.
  D. On the network ACLs for the database subnets, create an outbound Allow rule of type TCP with the ephemeral port range and the destination as the third web subnet.

• Question 160:
