  • A. Maintenance mode is unable to migrate all virtual machines from the host.
  • B. There is a large number of virtual machines that must be migrated from the host.
  • C. VMware High Availability is in the process of reconfiguring the cluster.

An administrator has been tasked with upgrading an existing host from ESX 4.1 to ESXi6.x. The existing host has only vSwitch0 with all the default settings.
The upgraded host will have the following new requirements:
1. 116 virtual machines will be connected.
2. Four uplinks configured for port-based load balancing.
3. The switch will include a secondary heartbeat network for HA. Which two statements are true about this configuration? (Choose two.)

✑ An administrator wants to add a web server to an existing multi-tier application consisting of three virtual machines:
✑ A web server
✑ A database server

An administrator is performing upgrades to ESXi 6.x from ESX 3.x and ESX 4.x hosts. What is true about this procedure?

  • A. A direct, in-place upgrade can be performed only on ESX 4.1 and later hosts.
  • B. ESX 3.x hosts can be upgraded, but require an upgrade to 4.x before 5.x.
  • C. A direct, in-place upgrade can be performed only on ESX 4.5 and later hosts.
  • D. A direct, in-place upgrade can be performed only on ESX 3.5 and later hosts.

Answer: B
