A company needs to ensure strict adherence to a budget for 25 applications deployed on AWS. Separate teams are responsible for storage, compute, and database costs. A SysOps administrator must implement an automated solution to alert each team when their projected spend will exceed a quarterly amount that has been set by the finance department. The solution cannot incur additional compute, storage, or database costs.
Which solution will meet these requirements?

A. Configure AWS Cost and Usage Reports to send a daily report to an Amazon S3 bucket. Create an AWS Lambda function that will evaluate spend by service and notify each team by using Amazon Simple Notification Service (Amazon SNS) notifications. Invoke the Lambda function when a report is placed in the S3 bucket.
B. Configure AWS Cost and Usage Reports to send a daily report to an Amazon S3 bucket. Create a rule in Amazon EventBridge (Amazon CloudWatch Events) to evaluate the spend by service and notify each team by using Amazon Simple Queue Service (Amazon SQS) when the cost threshold is exceeded.
C. Use AWS Budgets to create one cost budget and select each of the services in use. Specify the budget amount defined by the finance department along with the forecasted cost threshold. Enter the appropriate email recipients for the budget.
D. Use AWS Budgets to create a cost budget for each team, filtering by the services they own. Specify the budget amount defined by the finance department along with a forecasted cost threshold. Enter the appropriate email recipients for each budget.

A company has a large on-premises tape backup solution. The company has started to use AWS Storage Gateway. The company created a Tape Gateway to replace the existing on-premises hardware. The company's backup engineer noticed that some of the backup jobs that were supposed to write to AWS failed to run because of a "Not Enough Space" error.

The company does not want these failures to happen again. The company also wants to consistently have enough tape available on AWS.

What is the MOST operationally efficient way for a SysOps administrator to meet these requirements?

A. Create an AWS Lambda function that runs on an hourly basis and checks how many tapes have available space. If the available tapes are below a certain threshold, provision more.
B. Install the Amazon CloudWatch agent on the on-premises system. Push the log files to a CloudWatch log group. Create an AWS Lambda function that creates more tapes when the "Not Enough Space" error appears. Create a metric filter and a metric alarm that launches the Lambda function.
C. Create an additional Tape Gateway with its own set of tapes. Configure Amazon Simple Notification Service (Amazon SNS) to send a notification to the backup engineer if the tapes that are associated with the primary Tape Gateway do not have available space.
D. Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

A company has a public web application that experiences rapid traffic increases after advertisements appear on local television. The application runs on Amazon EC2 instances that are in an Auto Scaling group. The Auto Scaling group is not keeping up with the traffic surges after an advertisement runs. The company often needs to scale out to 100 EC2 instances during the traffic surges.

The instance startup times are lengthy because of a boot process that creates machine-specific data caches that are unique to each instance. The exact timing of when the advertisements will appear on television is not known. A SysOps administrator must implement a solution so that the application can function properly during the traffic surges.

Which solution will meet these requirements?

A. Create e warm pool. Keep enough instances in the Stopped state to meet the increased demand.
B. Start 100 instances. Allow the boot process to finish running. Store this data on the instance store volume before stopping the instances.
C. Increase the value of the instance warmup time in the scaling policy
D. Use predictive scaling for the Auto Scaling group.

A company is rolling out a new version of its website. Management wants to deploy the new website in a limited rollout to 20% of the company’s customers. The company uses Amazon Route 53 for its website’s DNS solution.

Which configuration will meet these requirements?

A. Create a failover routing policy. Within the policy, configure 80% of the website traffic to be sent to the original resource. Configure the remaining 20% of traffic as the failover record that points to the new resource.
B. Create a multivalue answer routing policy. Within the policy, create 4 records with the name and IP address of the original resource. Configure 1 record with the name and IP address of the new resource.
C. Create a latency-based routing policy. Within the policy, configure a record pointing to the original resource with a weight of 80. Configure a record pointing to the new resource with a weight of 20.
D. Create a weighted routing policy. Within the policy, configure a weight of 80 for the record pointing to the original resource. Configure a weight of 20 for the record pointing to the new resource.

A SysOps administrator is unable to launch Amazon EC2 instances into a VPC because there are no available private IPv4 addresses in the VPC.

Which combination of actions must the SysOps administrator take to launch the instances? (Choose two.)

A. Associate a secondary IPv4 CIDR block with the VPC.
B. Associate a primary IPv6 CIDR block with the VPC.
C. Create a new subnet for the VPC.
D. Modify the CIDR block of the VPC.
E. Modify the CIDR block of the subnet that is associated with the instances.

A team of developers is using several Amazon S3 buckets as centralized repositories. Users across the world upload large sets of files to these repositories. The development team's applications later process these files.

A SysOps administrator sets up a new S3 bucket, DOC-EXAMPLE-BUCKET, to support a new workload, The rew S3 bucket also receives regular uploads cf large sets of files from users worldwide. When the new S3 bucket is put into production, the upload performance from certain geographic areas is lower than the upload performance that the existing $3 buckets provide

What should the SysOps administrator do to remediate this issue?

A. Provision an Amazon ElastiCache for Redis cluster for the new S3 bucket. Provide the developers with the configuration endpoint of the cluster for use in their API calls
B. Add the new S3 bucket to a new Amazon CloudFront distribution. Provide the developers with the domain name of the new distribution for use in their API calls.
C. Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.
D. Use S3 multipart upload for the new S3 bucket. Verify that the developers are using Region-specific S3 endpoint names such as DOC-EXAMPLE-BUCKETS3, [Region] amazonaws.com in their API calls.

A company hosts a web portal on Amazon EC2 instances. The web portal uses an Elastic Load Balancer (ELB) and Amazon Route 53 for its public DNS service.
The ELB and the EC2 instances are deployed by way of a single AWS CloudFormation stack in the us-east-1 Region. The web portal must be highly available across multiple Regions.
Which configuration will meet these requirements?

A. Deploy a copy of the stack in the us-west-2 Region. Create a single start of authority (SOA) record in Route 53 that includes the IP address from each ELB. Configure the SOA record with health checks. Use the ELB in us-east-1 as the primary record and the ELB in us-west-2 as the secondary record.
B. Deploy a copy of the stack in the us-west-2 Region. Create an additional A record in Route 53 that includes the ELB in us-west-2 as an alias target. Configure the A records with a failover routing policy and health checks. Use the ELB in us-east-1 as the primary record and the ELB in us-west-2 as the secondary record.
C. Deploy a new group of EC2 instances in the us-west-2 Region. Associate the new EC2 instances with the existing ELB, and configure load balancer health checks on all EC2 instances. Configure the ELB to update Route 53 when EC2 instances in us-west-2 fail health checks.
D. Deploy a new group of EC2 instances in the us-west-2 Region. Configure EC2 health checks on all EC2 instances in each Region. Configure a peering connection between the VPCs. Use the VPC in us-east-1 as the primary record and the VPC in us-west-2 as the secondary record.
