VMware Telco Cloud Automation: Install, Configure, Manage [V1.8] — Lesson 1: Telco cloud concepts, TCA architecture, appliance roles, management and workload domains, Kubernetes infrastructure, network functions, prerequisites, DNS, NTP, certificates, and sizing

Learning Objectives

• Translate a realistic infrastructure or application requirement into an executable approach for Telco cloud concepts, TCA architecture, appliance roles, management and workload domains, Kubernetes infrastructure, network functions, prerequisites, DNS, NTP, certificates, and sizing.
• Use TCA deployment blueprint and prerequisite readiness record to verify configuration, connectivity, security, and expected behavior.
• Explain how to recover safely when appliance services starting while certificate names do not match platform endpoints occurs.

Detailed Topics

• Telco cloud concepts
• TCA architecture
• Appliance roles
• Management and workload domains
• Kubernetes infrastructure
• Network functions
• Prerequisites
• DNS
• NTP
• Certificates
• And sizing
• Decision ownership, prerequisites, and acceptance evidence for Telco cloud concepts, TCA architecture, appliance roles, management and workload domains, Kubernetes infrastructure, network functions, prerequisites, DNS, NTP, certificates, and sizing
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The demonstration traces Telco cloud concepts, TCA architecture, appliance roles, management and workload domains, Kubernetes infrastructure, network functions, prerequisites, DNS, NTP, certificates, and sizing from requirement through execution and review. Learners see where evidence should be collected, how TCA deployment blueprint and prerequisite readiness record supports validation, and which warning signs require investigation.

Hands-On Exercise

Complete a guided task covering Telco cloud concepts, TCA architecture, appliance roles, management and workload domains, Kubernetes infrastructure, network functions, prerequisites, DNS, NTP, certificates, and sizing. Establish a working baseline, reproduce “appliance services starting while certificate names do not match platform endpoints,” isolate the responsible configuration or dependency, apply a reversible fix, and update TCA deployment blueprint and prerequisite readiness record with before-and-after proof.

1. Define the requirement and identify dependencies before changing the environment.
2. Create a baseline result that can be compared with later changes.
3. Reproduce the exception and test one hypothesis at a time.
4. Complete the evidence record and obtain peer or instructor review.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for Telco cloud concepts, TCA architecture, appliance roles, management and workload domains, Kubernetes infrastructure, network functions, prerequisites, DNS, NTP, certificates, and sizing.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how TCA deployment blueprint and prerequisite readiness record should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

Avoid changing multiple settings at once while troubleshooting Telco cloud concepts, TCA architecture, appliance roles, management and workload domains, Kubernetes infrastructure, network functions, prerequisites, DNS, NTP, certificates, and sizing. Preserve the failing example, review TCA deployment blueprint and prerequisite readiness record, and verify whether “appliance services starting while certificate names do not match platform endpoints” is the root cause. After remediation, confirm downstream effects and add a monitoring action.

Validation Checklist

• Prerequisites and role permissions for Telco cloud concepts, TCA architecture, appliance roles, management and workload domains, Kubernetes infrastructure, network functions, prerequisites, DNS, NTP, certificates, and sizing are confirmed before execution.
• The observed result agrees with expected values documented in TCA deployment blueprint and prerequisite readiness record.
• Exceptions are explained with evidence instead of being hidden by manual correction.
• The final record names the approver, monitoring point, and next improvement action.

Lesson Outcome

Learners can apply Telco cloud concepts, TCA architecture, appliance roles, management and workload domains, Kubernetes infrastructure, network functions, prerequisites, DNS, NTP, certificates, and sizing, explain the decisions made, and defend the result with TCA deployment blueprint and prerequisite readiness record.
