An administrator has been tasked with upgrading an exsiting host from ESX 4.1 to ESXi 5.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.)
A.
The Service Console Port will be removed during the upgrade
B.
The configuration requires only one VMkernel Port
C.
The default vSwitch0 is sufficient for this configuration
D.
A change to vSwitch0 Properties is required
I’m pretty sure the answer is A and C on this one. 116 VMs + 2 for heartbeats with 2 left over and then 8 reserved for uplinks of which only 4 are needed. So the default vSwitch0 should be sufficient unless someone can show me otherwise. Isn’t that correct?
Requirements are 121 ports (116VMs + 4 Uplinks + 1 vmkernel) since a standard vSwitch has 120 ports, this will not be sufficient to address the requirements.
Explanation:
ESXi didn’t have Service Console port
Page 13 from vsphere-esxi-vcenter-server-50-networking-guide.pdf
A vSphere standard switch models a physical Ethernet switch. The default number of logical ports for a standard switch is 120. You can connect one network adapter of a virtual machine to each port.
(This example has 116 vms so you have only 4 ports remaining.)
Each uplink adapter associated with a standard switch uses one port.
(This example has 4, therefore all ports are used, and there are none left over for the heartbeat. The Heartbeat will use a VMkernel Port in addition to the VMkernel Port required for the switch. That rules out answer B.)
Each logical port on the standard switch is a member of a single port group. Each standard switch can also have one or more port groups assigned to it. For information about maximum allowed ports and port groups, see the Configuration Maximums documentation.
