- Apply vSAN health check analysis to identify network misconfigurations, disk errors, and cluster capacity warnings.
- Analyze vSAN object placement and component distribution to troubleshoot data availability and compliance failures.
- Analyze vSAN performance issues including high latency, congestion, and resync impact on workload performance.
- Design a vSAN monitoring and maintenance strategy with health check schedules, disk replacement procedures, and capacity thresholds.
External Storage Issues
- Apply external storage troubleshooting for path failures, VMFS metadata corruption, NFS mount issues, and multipathing errors.
- Apply APD (All Paths Down) and PDL (Permanent Device Loss) diagnosis and recovery procedures for SAN storage failures.
- Analyze storage performance degradation identifying queue depth saturation, path congestion, and array-side throttling.
- Analyze VMFS lock contention and metadata issues that prevent VM power operations or datastore access.
- Design storage troubleshooting procedures with diagnostic commands, vendor escalation paths, and data recovery playbooks.
4
Domain 4: Network Troubleshooting
2 topics
NSX Issues
- Apply NSX troubleshooting for tunnel endpoint failures, segment connectivity loss, and control plane synchronization issues.
- Apply NSX Traceflow to verify packet paths through logical switches, distributed routers, and firewalls for connectivity diagnosis.
- Analyze NSX distributed firewall rule processing to identify rules blocking legitimate traffic or allowing unauthorized access.
- Analyze NSX Manager cluster health, Corfu database status, and controller synchronization to troubleshoot management plane issues.
- Design NSX troubleshooting procedures with Traceflow workflows, Edge CLI diagnostics, and escalation criteria for complex issues.
vSphere Networking Issues
- Apply virtual switch troubleshooting for port group misconfiguration, VLAN tagging errors, uplink failures, and NIC teaming issues.
- Apply VMkernel connectivity troubleshooting for vMotion failures, vSAN communication issues, and management network connectivity loss.
- Analyze network partition scenarios in vSphere clusters determining impact on HA, DRS, and vSAN operations.
- Analyze physical-virtual network boundary issues including MTU mismatches, LACP negotiation failures, and trunk VLAN filtering.
- Design a network validation and troubleshooting framework with connectivity tests, performance benchmarks, and diagnostic procedures.
