Which two statements below could explain why the vSphere Client is reporting N/A for hyperthreading? (Choose two.)
The physical CPUs in the host do not support hyperthreading.
A.
Hyperthreading is disabled in the host’s BIOS.
B.
The physical CPUs in the host are not multi-core.
C.
The number of CPUs meets or exceeds the maximum without hyperthreading.
Explanation:
In the exhibit,the processors cores per sockets is 1 ,that means the physical CPUs in the host are not multi-core.But in reality,this cpu type is multi-core actually,so if there’s only one answer could be choose,it will be the second one.

A. The physical CPUs in the host do not support hyperthreading.
B. Hyperthreading is disabled in the host’s BIOS.
C. The physical CPUs in the host are not multi-core.
D. The number of CPUs meets or exceeds the maximum without hyperthreading.
Answer:
A + B = No Hyperthreading
C – multi-core and HT are different, a single core can be HT’d
D – Essentials has a 2 CPU limit, but Logical CPUs per host is 160

There is a problem with this question. The correct answers are in fact A & B, however A is actually “The physical CPUs in the host do not support hyperthreading”, and B is “Hyperthreading is disabled in the host’s BIOS”. One person made this mistake and now all of the test dumps have copied it.

In other words the real “A” is missing from the multi-choice answers.

Read the options like below, then answer is A and B
A.
The physical CPUs in the host do not support hyperthreading.
B.
Hyperthreading is disabled in the host’s BIOS.
C.
The physical CPUs in the host are not multi-core.
D.
The number of CPUs meets or exceeds the maximum without hyperthreading.

A socket is a single package that can have one or more physical CPUs, with each core having one or more logical CPU (LCPUs) or threads.
Agreed that the answers are:
– The physical CPUs in the host do not support hyperthreading — A
– Hyperthreading is disabled in the host’s BIOS — B
When you don’t have those two features listed above on your CPU, you’re guaranteed not to have hyperthreading capability.
– The physical CPUs in the host are not multi-core — you don’t need multi-core CPU to have the hyperthread availability…just needs to be supported by your CPU.
Hyperthread means your physical CPU has the ability to process / execute two thread simultaneously by creating another logical CPU.
