CloudWatch Logs allows you to create __________ to trigger actions based on log data patterns.

  • Event rules
  • Log groups
  • Log metric filters
  • Log streams
Log metric filters in CloudWatch Logs enable you to define patterns in log data and create metrics based on those patterns, allowing you to trigger actions.

__________ is a feature of CloudWatch Logs that enables you to archive log data to Amazon S3 for long-term storage.

  • Log archival
  • Log backup
  • Log retention
  • Log rotation
Log archival is a feature of CloudWatch Logs that enables you to archive log data to Amazon S3 for long-term storage.

CloudWatch Logs supports integration with AWS __________ for automated log analysis and response.

  • AWS Lambda
  • Amazon RDS
  • Amazon SQS
  • CloudWatch Alarms
AWS Lambda can be integrated with CloudWatch Logs for automated log analysis and response, enabling you to process log data and trigger actions based on defined logic.

Scenario: Your application's performance is degrading, and you suspect it's due to excessive logging. How would you use CloudWatch Logs to identify and mitigate this issue?

  • Disable logging altogether
  • Increase logging verbosity
  • Manually review log files
  • Set up log metric filters and alarms
By setting up log metric filters and alarms in CloudWatch Logs to extract specific patterns from log events related to performance degradation and alerting when these metrics exceed thresholds, you can identify and mitigate issues caused by excessive logging.

Scenario: You need to comply with regulatory requirements to retain log data for seven years. How would you configure CloudWatch Logs to meet this requirement effectively?

  • Create retention policies
  • Increase log group size
  • Manually delete old log data
  • Use CloudTrail instead
By creating retention policies in CloudWatch Logs, you can specify the retention period for log data, ensuring that it is retained for the required duration of seven years to comply with regulatory requirements.

How does AWS X-Ray help in understanding application performance?

  • Generates synthetic traffic
  • Manages server resources
  • Optimizes network bandwidth
  • Provides insights into latency and errors
AWS X-Ray provides insights into latency and errors by tracing requests and capturing data such as response times and error rates, helping you identify performance bottlenecks.
