Certified: The CompTIA AutoOps+ Audio Course

This episode explains how subnet design, route tables, and DNS configuration shape whether automation succeeds cleanly or fails in confusing ways, which is why these concepts show up in AutoOps+ scenarios. You will learn what subnets represent in practical operations, how routing decisions control reachability between workloads, and why DNS is often the hidden dependency behind “service unavailable” and “timeout” errors. We connect exam-relevant definitions to real patterns like separating public and private subnets, restricting east-west traffic, and using route tables to force traffic through inspection points or NAT paths. You will also learn best practices for naming and documenting DNS zones and records so automation can target stable endpoints, plus troubleshooting steps like validating resolver settings, checking split-horizon behavior, and confirming that routes exist in both directions for required paths.
