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?
- A . The kubeconfig file
- B . The kube-proxy Amazon EKS add-on
- C . The Fargate profile
- D . The eks-connector.yaml file
A
Explanation:
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 needs to configure automatic rotation for Amazon RDS database credentials.
The credentials must rotate every 30 days. The solution must integrate with Amazon RDS.
Which solution will meet these requirements with the LEAST operational overhead?
- A . Store the credentials in AWS Systems Manager Parameter Store as a secure string. Configure automatic rotation with a rotation interval of 30 days.
- B . Store the credentials in AWS Secrets Manager. Configure automatic rotation with a rotation interval of 30 days.
- C . Store the credentials in a file in an Amazon S3 bucket. Deploy an AWS Lambda function to automatically rotate the credentials every 30 days.
- D . Store the credentials in AWS Secrets Manager. Deploy an AWS Lambda function to automatically rotate the credentials every 30 days.
B
Explanation:
Storing the credentials in AWS Secrets Manager and configuring automatic rotation with a rotation interval of 30 days is the most efficient way to meet the requirements with the least operational overhead. AWS Secrets Manager automatically rotates the credentials at the specified interval, so there is no need for an additional AWS Lambda function or manual rotation. Additionally, Secrets Manager is integrated with Amazon RDS, so the credentials can be easily used with the RDS database.
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?
- A . Specify the capacity-optimized allocation strategy for Spot Instances. Add more instance types to the Auto Scaling group.
- B . Specify the capacity-optimized allocation strategy for Spot Instances. Increase the size of the instances in the Auto Scaling group.
- C . Specify the lowest-price allocation strategy for Spot Instances. Add more instance types to the Auto Scaling group.
- D . Specify the lowest-price allocation strategy for Spot Instances. Increase the size of the instances in the Auto Scaling group.
A
Explanation:
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.
A company stores its data in an Amazon S3 bucket. The company is required to classify the data and find any sensitive personal information in its S3 files.
Which solution will meet these requirements?
- A . Create an AWS Config rule to discover sensitive personal information in the S3 files and mark them as noncompliant.
- B . Create an S3 event-driven artificial intelligence/machine learning (AI/ML) pipeline to classify sensitive personal information by using Amazon Recognition.
- C . Enable Amazon GuardDuty. Configure S3 protection to monitor all data inside Amazon S3.
- D . Enable Amazon Macie. Create a discovery job that uses the managed data identifier.
D
Explanation:
Amazon Macie is a security service designed to help organizations find, classify, and protect sensitive data stored in Amazon S3. Amazon Macie uses machine learning to automatically discover, classify, and protect sensitive data in Amazon S3. Creating a discovery job with the managed data identifier will allow Macie to identify sensitive personal information in the S3 files and classify it accordingly. Enabling AWS Config and Amazon GuardDuty will not help with this requirement as they are not designed to automatically classify and protect data.
A company has an application that customers use to search for records on a website. The application’s data is stored in an Amazon Aurora DB cluster. The application’s usage varies by season and by day of the week.
The website’s popularity is increasing, and the website is experiencing slower performance because of increased load on the DB cluster during periods of peak activity. The application logs show that the performance issues occur when users are searching for information. The same search is rarely performed multiple times.
A SysOps administrator must improve the performance of the platform by using a solution that maximizes resource efficiency.
Which solution will meet these requirements?
- A . Deploy an Amazon ElastiCache for Redis cluster in front of the DB cluster. Modify the application to check the cache before the application issues new queries to the database. Add the results of any queries to the cache.
- B . Deploy an Aurora Replica for the DB cluster. Modify the application to use the reader endpoint for search operations. Use Aurora Auto Scaling to scale the number of replicas based on load. Most Voted
- C . Use Provisioned IOPS on the storage volumes that support the DB cluster to improve performance sufficiently to support the peak load on the application.
- D . Increase the instance size in the DB cluster to a size that is sufficient to support the peak load on the application. Use Aurora Auto Scaling to scale the instance size based on load.
B

The security team is concerned because the number of AWS Identity and Access Management (IAM) policies being used in the environment is increasing. The team tasked a SysOps administrator to report on the current number of IAM policies in use and the total available IAM policies.
Which AWS service should the administrator use to check how current IAM policy usage compares to current service limits?
- A . AWS Trusted Advisor
- B . Amazon Inspector
- C . AWS Config
- D . AWS Organizations
A company has a stateless application that is hosted on a fleet of 10 Amazon EC2 On-Demand Instances in an Auto Scaling group. A minimum of 6 instances are needed to meet service requirements.
Which action will maintain uptime for the application MOST cost-effectively?
- A . Use a Spot Fleet with an On-Demand capacity of 6 instances.
- B . Update the Auto Scaling group with a minimum of 6 On-Demand Instances and a maximum of 10 On-Demand Instances.
- C . Update the Auto Scaling group with a minimum of 1 On-Demand Instance and a maximum of 6 On-Demand Instances.
- D . Use a Spot Fleet with a target capacity of 6 instances.
A SysOps administrator has launched a large general purpose Amazon EC2 instance to regularly process large data files. The instance has an attached 1 TB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volume. The instance also is EBS-optimized. To save costs, the SysOps administrator stops the instance each evening and restarts the instance each morning.
When data processing is active, Amazon CloudWatch metrics on the instance show a consistent 3.000 VolumeReadOps. The SysOps administrator must improve the I/O performance while ensuring data integrity.
Which action will meet these requirements?
- A . Change the instance type to a large, burstable, general purpose instance.
- B . Change the instance type to an extra large general purpose instance.
- C . Increase the EBS volume to a 2 TB General Purpose SSD (gp2) volume.
- D . Move the data that resides on the EBS volume to the instance store.
With the threat of ransomware viruses encrypting and holding company data hostage, which action should be taken to protect an Amazon S3 bucket?
- A . Deny Post. Put. and Delete on the bucket.
- B . Enable server-side encryption on the bucket.
- C . Enable Amazon S3 versioning on the bucket.
- D . Enable snapshots on the bucket.
A SysOps administrator is evaluating Amazon Route 53 DNS options to address concerns about high availability for an on-premises website. The website consists of two servers: a primary active server and a secondary passive server. Route 53 should route traffic to the primary server if the associated health check returns 2xx or 3xx HTTP codes. All other traffic should be directed to the secondary passive server. The failover record type, set ID. and routing policy have been set appropriately for both primary and secondary servers.
Which next step should be taken to configure Route 53?
- A . Create an A record for each server. Associate the records with the Route 53 HTTP health check.
- B . Create an A record for each server. Associate the records with the Route 53 TCP health check.
- C . Create an alias record for each server with evaluate target health set to yes. Associate the records with the Route 53 HTTP health check.
- D . Create an alias record for each server with evaluate target health set to yes. Associate the records with the Route 53 TCP health check.
