VMware Telco Cloud Automation: Install, Configure, Manage [V1.8] — Lesson 4: Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover

Learning Objectives

• Break down the prerequisites, components, roles, and decision points involved in Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover.
• Complete a controlled activity for Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover and capture TCA operations runbook and incident-response checklist.
• Challenge the result with a failed lifecycle task being retried without clearing the original orchestration lock, then justify the corrective action.

Detailed Topics

• Alarms
• Logs
• Topology
• Task histories
• Failure recovery
• Backup
• Upgrades
• Access control
• API use
• Troubleshooting
• And operations handover
• Decision ownership, prerequisites, and acceptance evidence for Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

Using realistic infrastructure, identities, and workloads, the instructor demonstrates Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover. Checkpoints are captured in TCA operations runbook and incident-response checklist, with discussion of alternatives, side effects, and acceptance conditions.

Hands-On Exercise

Configure and test Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover with representative infrastructure or application data. Use “a failed lifecycle task being retried without clearing the original orchestration lock” as the troubleshooting challenge, compare hypotheses, retest the affected path, and complete TCA operations runbook and incident-response checklist for review.

1. Record the starting state, assumptions, identities, topology, and expected outcome.
2. Execute the planned workflow and collect evidence at each material checkpoint.
3. Test one valid path, one boundary condition, and the stated failure scenario.
4. Document the correction, retest result, rollback option, and follow-up owner.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how TCA operations runbook and incident-response checklist should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

Diagnose Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover by checking effective state, ownership, dependencies, health, logs, and recent changes. Use TCA operations runbook and incident-response checklist to locate the earliest divergence. Treat “a failed lifecycle task being retried without clearing the original orchestration lock” as a hypothesis until the same test passes after correction and under a boundary condition.

Validation Checklist

• The scope of Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover is clear, including what is deliberately excluded from the test.
• Evidence in TCA operations runbook and incident-response checklist supports each material decision and outcome.
• A negative test demonstrates that controls reject or expose an invalid condition.
• Open risks, owners, due actions, and production safeguards are documented.

Lesson Outcome

Learners can apply Alarms, logs, topology, task histories, failure recovery, backup, upgrades, access control, API use, troubleshooting, and operations handover, explain the decisions made, and defend the result with TCA operations runbook and incident-response checklist.
