An administrator has been tasked with creating a vSphere Standard Switch (vSS) for an ESXi host with the following specifications:
1. 116 virtual machines will be connected to the switch,
2. The switch wall have four uplinks configured for port-based load balancing.
3. The switch will act as a secondary heartbeat network for HA.
Which two statements are true about this configuration? (Choose two)
A.
The configuration requires a Service Console Port
B.
The configuration requires a VMkernel port
C.
A vSS created with default settings in the vSphere Client is insufficient for this configuration
D.
A vSS created with 128 ports using the vSphere CLI is sufficient for this configuration
Explanation:
ESXi didn’t have Service Console port
Page 11 from vsphere-esxi-vcenter-server-50-networking-guide.pdf
On this way I understand that my requirements are 121 ports (116VMs + 4 Uplinks + 1 vmkernel) since a standard vSwitch has 120 ports, this will not be sufficient to address my requirements. Is that right?
I count 121 as well.
Can someone please explain why only 120 are needed
It was always my understanding that a port group with 120 ports actually had 128, with 8 ‘reserved’ for internal use. A vicfg-vswitch list will show 128 ports and I have seen screen shots with old Vi3 vSS set with 56 ports and more than that number of VMs on it, essentially a 64 port switch.
I do agree that the ‘real’ port count is 116 x VMs, 4 pNICs and a VMK port; 121 ports used in total and if my above statement is correct then VMware are messin’ with or heads.
The correct answer is: A vSS created with default settings in the vSphere Client is insufficient for this configuration, as explained before because it is INSUFFICIENT for this configuration
While the correct answer is “A vSS created with default settings in the vSphere Client is insufficient for this configuration”, the total should be 122 = vSS(1), 116 VM (116), 4 pNICs (4), VMK (1). When you create a vSS “Used Ports” will be 1.
