VMware VCP 6.7-DCV – Objective 1.7 – Describe and identify resource pools and use cases

The following notes will assist you to prepare for this objective:

  • Resource management is an essential skills for passing VCP-DCV
    • What resource are you being asked to control?
    • Different resources have different controls
  • Know the resource pool settings
    • You need to be able to select the right settings for a scenario
    • Proportional share allocation
  • Why use resource pools

VMware VCP 6.7-DCV – Objective 1.6 – Describe and differentiate among vSphere, HA, DRS, and SDRS functionality

The following notes will assist you to prepare for this objective:

  • HA has come a long way, don’t rely on legacy knowledge of HA to meet objective
  • Learn the newer features, pre-reqs and limitations of:
    • Proactive HA
    • Orchestrated Restart
    • Fault Tolerance (FT) vSMP
  • HA can’t work around everything
    • For example datastore connectivity loss or unable to satisfy reservation
  • Ensure you can explain the basic modes of DRS
    • Disable, Manual, Partial, Full Automated, per-VM
  • DRS has come a long way
    • Predictive DRS
    • Limitations of vMotion have been overcome
  • What are the vMotion pre-reqs?
    • CPU compatibility
    • Network configuration
    • Compatible virtual hardware
  • What virtual hardware options can and cannot be migrated with DRS?
  • SDRS often gets overlooked
    • Remember it has 2 dimensions to optimization
      • Space utilization & I/O latency
      • What are you being asked in the question?
