A company’s data processing workflow uses AWS Lambda to interact with other AWS services, including AWS Step Functions, Amazon DynamoDB, and Amazon S3. The Lambda functions make several API calls to these services as a part of the workflow. AWS CloudTrail has been enabled in the AWS Region and is logging to Amazon CloudWatch Logs. The Lambda functions are also logging to CloudWatch Logs.
A SysOps administrator notices that a specific Lambda function in the workflow is taking longer to run than it did last month. The SysOps administrator needs to determine the parts of the Lambda function that are experiencing higher-than-normal response times.
What solution will accomplish this?
A. Analyze logs in CloudWatch Logs for the timestamps at which the API calls are made while the Lambda function is running.
Compare with the logs from the previous month.
B. Enable AWS X-Ray for the function.
Analyze the service map and traces to help identify the API calls with anomalous response times.
C. Search CloudTrail logs for the calls from the Lambda function.

A SysOps administrator is responsible for managing a fleet of Amazon EC2 instances. These EC2 instances upload build artifacts to a third-party service. The third-party service recently implemented strict IP whitelisting that requires all build uploads to come from a single IP address.
What change should the systems administrator make to the existing build fleet to comply with this new requirement?
A. Move all of the EC2 instances behind a NAT gateway and provide the gateway IP address to the service.

A SysOps administrator manages an AWS CloudFormation template that provisions Amazon EC2 instances, an Elastic Load Balancer, and Amazon RDS instances. As part of an ongoing transformation project, CloudFormation stacks are being created and deleted continuously. The administrator needs to ensure that the RDS instances continue running after a stack has been deleted.
Which action should be taken to meet these requirements?
A. Edit the template to remove the RDS resources and update the stack.
B. Enable termination protection on the stack.
C. Set the DeletionPolicy attribute for RDS resources to Retain in the template.

A streaming company is using AWS resources in the us-east-1 Region for its production environment. The web tier of the streaming site runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an EC2 Auto Scaling group across multiple Availability Zones. The Auto Scaling group is configured to scale when the CPU utilization of the instances is greater than 75%. The user database is hosted on an Amazon RDS MySQL cluster, and video content is stored within an Amazon S3 bucket. Amazon CloudWatch metrics show that the RDS MySQL Multi-AZ DB instance has around 16 GB of memory free and an average CPU utilization of 70%. It is taking users in Asia several seconds longer to access the streaming website.
Which combination of actions will improve the access load times? (Choose two.)
A. Configure RDS MySQL Multi-AZ to reduce RDS CPU and RAM utilization and distribute queries to multiple Availability Zones.
B. Modify the EC2 Auto Scaling group so it will scale horizontally when CPU utilization is 50%.
C. Provision a second production environment in the Asia Pacific Region and use an ALB to distribute cross-Region access.
D. Provision a second production environment in the Asia Pacific Region and use Amazon Route 53 latency-based routing.
E. Set up an Amazon CloudFront distribution to handle static content for users accessing it from different geographic locations.
A large company has multiple AWS accounts that are assigned to each department. A SysOps administrator needs to help the company reduce overhead and manage its AWS resources more easily.

An application is running on Amazon EC2 instances and storing all application data in Amazon S3. The company wants to archive all files older than 30 days to reduce costs. Archived files are used for auditing purposes only; however, the audit team may need to retrieve files in under a minute.
How should the SysOps administrator implement these requirements?
A. Configure an S3 bucket policy to move all objects older than 30 days to S3 Standard-Infrequent Access (S3 Standard-IA).
B. Create a lifecycle rule to move all objects older than 30 days to S3 Glacier.

A company uses LDAP-based credentials and has a Security Assertion Markup Language (SAML) 2.0 identity provider. A SysOps administrator has configured various federated roles in a new AWS account to provide AWS Management Console access for groups of users that use the existing LDAP-based credentials. Several groups want to use the AWS CLI on their workstations to automate daily tasks. To enable them to do so, the SysOps administrator has created an application that authenticates a user and generates a SAML assertion
