Exam 220-1001 topic 1 question 93 discussion

Hi There, Can some pls explain a bit why SSD would be best choice here? I expected more RAM here. My thoughts are: normaly Storage space is already enough for multiple VM's, but RAM oftern only 8 or 16GB. So if I plan for future VMs I would need to add more RAM instead of Storage, as this would be for normaly already enough... Or is the question more focusing on the HDD vs. SSD aspect? But the question not refers that only a HDD is in the system. Also still RAM is more important than a SSD in my opinion. Thanks and regards

The most important component in starting to virtualize VMs is storage and then next are RAM and CPU cores. These 3 components ae important reqrments for VM, but where do you create a VM? in HDD hardware virtualization, so building more VMs are needed to scalate more RAM and more cores for CPU to run the host PC and guest VMs effectively.

It Has to be D

most laptop processors can not be removed. My gut says ram

From Mike Meyers "For good performance on a virtualization workstation, install lots and lots of RAM. ...RAM is the most important thing in virtualization" A good CPU is mentioned, but it's secondary to RAM

Hello everyone, Is there any person who is studying around here, who has passed a real exam? Are these questions the same ones that appear in a real exam? I want to present myself for the first time to a real exam next Thursday and the truth is that I am making a mess with these some answers that do not make much sense.

The question is what should be upgraded, CPU is not upgradable in laptops, while it is important, it asks what should be upgraded.

For me the answer B (SSD) is incorrect. The most important thing in a VMS are CPU and RAM. An SSD disc can help to win at reading and writing speed, but processes are developed in the CPU and RAM.

Given how CPU, RAM, and Storage are all needed for running multiple VM's, I think the question is pushing us towards looking at the fact that they are purchasing a laptop and you usually cannot easily replace a CPU in a laptop. So a higher end CPU should be provisioned first with RAM and SSD being upgraded later as things change.

has to be RAM because they are "running at the same time."

fIRSTprob i encountered adding additional VMs was RAM

Storage space is used by the Hyper-Visor to store OS for each VM, if choices were HDD or SSD would be confusing

Not enough RAM would the VMs very slow but run at the same time. Not enough SSD would not allow the OS on each machine to work as the OS has requirements to function. SSD is also quicker to access the storage for each machine at the same time. My first guess was RAM but thinking about it SSD makes more sense now.

The answer is RAM then CPU if they allow a second answer. If you don't have enough RAM it not possible to run a VM. For example, windows 10 require at least 2 GB of memory so if you only had 4GB of memory that would be too small to support multiple VMs. Jason Dion recommends that a workstation supporting multiple VMs needs at least : RAM: 16GB CPU: multiple processor cores (already has 4 cores) Storage: 512 GB of SSD Network Card: High speed (1 Gbps)

B. SSD

Don't forget that hypervisors have a function for flexibility that allows them to actively shrink their CPU and RAM allocation to the minimum needed however the only Storage size options are fixed or expandable so a VM is still taking X storage even while offline (no CPU/RAM usage). Also the RAM and CPU usage will stay relatively consistent once running but the cumulative storage space required for all VMs will only ever increase as more and more data is saved i.e. a 64Gb VM needs the same amount of CPU/RAM as an identical VM but with 128Gb storage.
