A Sysops administrator creates an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that uses AWS Fargate. The cluster is deployed successfully. The Sysops administrator needs to manage the cluster by using the kubect1 command line tool.
Which of the following must be configured on the Sysops administrator's machine so that kubect1 can communicate with the cluster API server?

1. A. The kubeconfig file
2. B. The kube-proxy Amazon EKS add-on
3. C. The Fargate profile
4. D. The eks-connector.yaml file

Correct Answer: A
The kubeconfig file is a configuration file used to store cluster authentication information, which is required to make requests to the Amazon EKS cluster API server. The kubeconfig file will need to be configured on the SysOps administrator's machine in order for kubectl to be able to communicate with the cluster API server.

A SysOps administrator is optimizing the cost of a workload. The workload is running in multiple AWS Regions and is using AWS Lambda with Amazon EC2 On-Demand Instances for the compute. The overall usage is predictable. The amount of compute that is consumed in each Region varies, depending on the users' locations.
Which approach should the SysOps administrator use to optimize this workload?

1. A. Purchase Compute Savings Plans based on the usage during the past 30 days
2. B. Purchase Convertible Reserved Instances by calculating the usage baseline.
3. C. Purchase EC2 Instance Savings Plane based on the usage during the past 30 days
4. D. Purchase Standard Reserved Instances by calculating the usage baseline.

Correct Answer: C

A company has a critical serverless application that uses multiple AWS Lambda functions. Each Lambda function generates 1 GB of log data daily in its own Amazon CloudWatch Logs log group. The company's security team asks for a count of application errors, grouped by type, across all of the log groups.
What should a SysOps administrator do to meet this requirement?

1. A. Perform a CloudWatch Logs Insights query that uses the stats command and count function.
2. B. Perform a CloudWatch Logs search that uses the groupby keyword and count function.
3. C. Perform an Amazon Athena query that uses the SELECT and GROUP BY keywords.
4. D. Perform an Amazon RDS query that uses the SELECT and GROUP BY keywords.

Correct Answer: A

A SysOps administrator must create a solution that immediately notifies software developers if an AWS Lambda function experiences an error.
Which solution will meet this requirement?

1. A. Create an Amazon Simple Notification Service (Amazon SNS) topic with an email subscription for each develope
2. B. Create an Amazon CloudWatch alarm by using the Errors metric and the Lambda function name as a dimensio
3. C. Configure the alarm to send a notification to the SNS topic when the alarm state reaches ALARM.
4. D. Create an Amazon Simple Notification Service (Amazon SNS) topic with a mobile subscription for each develope
5. E. Create an Amazon EventBridge (Amazon CloudWatch Events) alarm by using LambdaError as the event pattern and the SNS topic name as a resourc
6. F. Configure the alarm to send a notification to the SNS topic when the alarm state reaches ALARM.
7. G. Verify each developer email address in Amazon Simple Email Service (Amazon SES). Create an Amazon CloudWatch rule by using the LambdaError metric and developer email addresses as dimension
8. H. Configure the rule to send an email through Amazon SES when the rule state reaches ALARM.
9. I. Verify each developer mobile phone in Amazon Simple Email Service {Amazon SES). Create an Amazon EventBridge (Amazon CloudWatch Events) rule by using Errors as the event pattern and the Lambda function name as a resourc
10. J. Configure the rule to send a push notification through Amazon SES when the rule state reaches ALARM.

Correct Answer: A

- (Exam Topic 1)
A company has an application that runs only on Amazon EC2 Spot Instances. The instances run in an Amazon EC2 Auto Scaling group with scheduled scaling actions.
However, the capacity does not always increase at the scheduled times, and instances terminate many times a day. A Sysops administrator must ensure that the instances launch on time and have fewer interruptions.
Which action will meet these requirements?

1. A. Specify the capacity-optimized allocation strategy for Spot Instance
2. B. Add more instance types to the Auto Scaling group.
3. C. Specify the capacity-optimized allocation strategy for Spot Instance
4. D. Increase the size of the instances in the Auto Scaling group.
5. E. Specify the lowest-price allocation strategy for Spot Instance
6. F. Add more instance types to the Auto Scaling group.
7. G. Specify the lowest-price allocation strategy for Spot Instance
8. H. Increase the size of the instances in the Auto Scaling group.

Correct Answer: A
Specifying the capacity-optimized allocation strategy for Spot Instances and adding more instance types to the Auto Scaling group is the best action to meet the requirements. Increasing the size of the instances in the Auto Scaling group will not necessarily help with the launch time or reduce interruptions, as the Spot Instances could still be interrupted even with larger instance sizes.
