220-1101 - Virtualization and Cloud Computing (11% of the exam) - Section 4.2

Summarise aspects of client-side virtualization, including the purpose of virtual machines, hypervisor types, and resource and security requirements.

Explain the purpose of a virtual machine and a sandbox for testing, development, and isolation, and distinguish a Type 1 (bare-metal) hypervisor from a Type 2 (hosted) hypervisor. Identify the resource requirements a client needs to run VMs - CPU virtualization support, sufficient RAM, storage, and networking - and the security requirements that isolate guests from the host.

A technician is comparing hypervisor architectures for a lab. Which statement correctly distinguishes a Type 1 hypervisor from a Type 2 hypervisor?

AA Type 1 hypervisor is installed directly on the physical hardware, whereas a Type 2 hypervisor runs as software on top of an existing host operating system. Correct
BA Type 1 hypervisor runs as an application on top of a host operating system, whereas a Type 2 hypervisor is installed directly on the hardware.
CA Type 1 hypervisor supports only Linux guests, whereas a Type 2 hypervisor supports only Windows guests.
DA Type 1 hypervisor requires no CPU virtualization support, whereas a Type 2 hypervisor requires hardware-assisted virtualization to function.

Distinguish a Type 1 (bare-metal) hypervisor, installed on the hardware, from a Type 2 (hosted) hypervisor that runs on a host operating system. The defining difference is the installation layer: a Type 1 hypervisor loads directly on the physical hardware with no underlying operating system, while a Type 2 hypervisor executes as an application within an existing host operating system.

Why A is correct: Correct: Type 1 (bare-metal) sits directly on the hardware, while Type 2 (hosted) runs as an application above a conventional host operating system.

Why B is wrong: This is tempting because both types are being contrasted, but it reverses the definitions: the application-on-a-host model describes Type 2, not Type 1.

Why C is wrong: This sounds like a real limitation but is false: both hypervisor types are guest-agnostic and the distinction is where the hypervisor is installed, not which guest it runs.

Why D is wrong: This is plausible if you assume bare-metal avoids hardware needs, but it is wrong: both types benefit from and typically require CPU virtualization extensions.

Exam traps in Virtualization and Cloud Computing

Answers that look right on this material and are not. Each one is a distractor from a different question in the 220-1101 bank for this domain.

Virtual machines share a single pooled copy of the host RAM, so adding more guests never increases the total memory the host must provide.
Why it is wrong: This is tempting because hypervisors do manage memory efficiently, but each active guest still needs its own allocation, so total memory demand rises as guests are added.
A Trusted Platform Module chip that stores the encryption keys used by the guest operating systems.
Why it is wrong: A TPM is genuinely a firmware-era security feature, but it handles key storage and measured boot, not the CPU-level acceleration that virtual machines require.
A test-bed VM, a snapshot-based clone used to trial application patches before rolling them out across production desktops.
Why it is wrong: Patch testing is a legitimate VM use, but its goal is validating updates, not deliberately containing hostile code, so it does not describe malware isolation.
