   A team is assessing the technical debt in a network automation codebase. They have identified two areas: (1) a critical module with no tests and complex logic, and (2) a rarely-used utility with good tests but outdated comments. The team has limited sprint capacity. Which strategy best manages this debt?

   • APrioritize adding tests to the critical module and refactor it incrementally, while deferring the utility's comment updates.
   • BRefactor both areas in parallel to address all debt quickly.
   • CIgnore the critical module's lack of tests because it is working in production.
   • DUpdate the utility's comments first because it is a quick win.

   A production network automation service is intermittently failing to apply configurations to a subset of devices. The application logs show no errors, and the team cannot reproduce the issue in development. Which observability capability would be most useful to diagnose this intermittent issue?

   • ADistributed tracing that captures the full request path and timing for each configuration push.
   • BA configuration management database (CMDB) listing all devices and their current configurations.
   • CA dashboard showing the total number of configuration pushes per hour.
   • DA log aggregation system that stores all logs in a central location.

   • BManually updating configuration on each server
   • CIgnoring configuration differences between environments
   • DHardcoding environment-specific values directly in the source code
