Exam CV0-003 topic 1 question 174 discussion

Jesus these questions are so bad. You don't "upgrade" VM memory, you allocate more to them. Hypervisors don't have "memory", but Hyper-V will not even let you start a VM if there isn't enough host memory so the that conflicts with the suggested answer. But the other answers make even less sense lol.

Explanation: Many operating systems, especially older versions or specific editions, have memory limits based on licensing or architecture. For example: 32-bit OS: Typically cannot use more than 4GB of RAM. Certain editions of Windows Server: Have licensing-based RAM limitations. If the OS cannot recognize or utilize the additional memory, there will be no performance improvement.

This question... If the VM already has 8GB of RAM then it has to be a 64bit/x86 OS. If it is upgraded to 16GB then it still has to be an x86 OS.. How can it be an operating system memory limit? I know I referring to Windows here but D seems like a valid answer. I know you can argue in all kinds of different contextual points of view but this is mine.. First answer D, next answer would be B.

Operating system memory limit seems silly. It's 2024 man.

Operating System Memory Limit (Option B): Many operating systems have memory limits or restrictions on how much memory an application or process can utilize. If the operating system has a limit set at 8GB, for example, even if you allocate 16GB to a VM, the operating system will only use up to its configured limit, and the additional memory won't provide any performance benefit.

I think the answer is Dynamic Memory Allocation. Even though more RAM was installed, the VMs instance will have to be powered off. Memory allocated, then turned back on to realize any benefit. Currently, the extra memory is only available to the host.

When upgrading the memory of VMs, it is crucial to consider the limitations imposed by the operating system running within the VM. If the operating system has a memory limit or restriction that is lower than the upgraded memory size, it will not utilize the additional memory beyond its limit, resulting in no performance benefit for users.

If there was insufficient memory on the hypervisor, the VMs would likely not be able to start or function properly after the upgrade. Each operating system has a maximum amount of RAM that it can handle, and if the VM's operating system has a limit of 8GB, then increasing the VM's memory to 16GB would not provide any additional benefit because the operating system wouldn't be able to utilize the extra memory.

Its A. The Vms are on premises. Therefore its very likely you have not got enough RAM to double the memory of the VMs. Yes the wording isnt perfect but I feel its pretty obvious what they meant

Seems the reference to "recently upgraded the memory of its on-premises VMs from 8GB to 16GB" is referring to the physical servers hosting the VM's & not the hypervisor/VM's settings, (since upgrading memory is only a physical attribute.) This denotes a physical upgrade (dedicated server - hosted in house & not cloud at all!) Take that premise as the foundation & then look at the Dynamic Memory Allocation - which could have remained unchanged since the "upgrade" - hence you need to up the allocation. Put simply, if you upgrade the physical memory - don't forget to increase dynamic memory resources to the VM's since you have more to distribute.

Maybe B? Over allocation? Wish they would stop word playing..

Maybe the VM doesn't need it and has dynamically assigned it back to the HV? \

Shouldn't it be B? Question does not specify which OS is on VM and OSs do have memory limitations https://www.compuram.de/blog/en/how-much-ram-can-be-addressed-under-the-current-32-bit-and-64-bit-operating-systems/ Question states that users are not experiencing any performance benefit, which means that VMs are running, but are not faster, which for me, eliminates A. I am going for B
