A company has an application that runs on AWS Lambda@Edge. The application serves content that varies based on the device that the viewer is using. Information about the number of hits by device type is written to logs that are stored in a log group in Amazon CloudWatch Logs. The company needs to publish an Amazon CloudWatch custom metric for each device type.
Which approach will meet these requirements?
A. Create a CloudWatch Logs Insights query to extract the device type information from the logs and to create a custom metric with device type as a dimension.
B. Create a CloudWatch metric filter to extract metrics from the log files with device type as a dimension.
C. Update the application to write its logs in the CloudWatch embedded metric format with device type as a dimension.
D. Configure the CloudWatch Logs agent for Lambda integration. Update the application to use the StatsD protocol to emit the metrics.
A developer is creating a website that will be hosted from an Amazon S3 bucket. The website must support secure browser connections. Which combination of actions must the developer take to meet this requirement? (Choose two.)

D. Configure the Amazon CloudFront distribution with an SSL/TLS certificate.
E. Configure the S3 bucket with an SSL/TLS certificate.
A developer is changing the configuration for a CPU-intensive AWS Lambda function that runs once an hour. The function usually takes 45 seconds to run, but sometimes the run time is up to 1 minute. The timeout parameter is set to 3
minutes, and all other parameters are set to default.

B. Increase the function's memory.
C. Redeploy the function by using Lambda layers.
D. Increase the function's reserved concurrency.
A developer is working on an ecommerce website. The developer wants to review server logs without logging in to each of the application servers individually. The website runs on multiple Amazon EC2 instances, is written in Python, and needs to be highly available.
How can the developer update the application to meet these requirements with MINIMUM changes?
A. Rewrite the application to be cloud native and to run on AWS Lambda, where the logs can be reviewed in Amazon CloudWatch.
B. Set up centralized logging by using Amazon Elasticsearch Service (Amazon ES), Logstash, and Kibana.
C. Scale down the application to one larger EC2 instance where only one instance is recording logs.
D. Install the unified Amazon CloudWatch agent on the EC2 instances. Configure the agent to push the application logs to CloudWatch.
