Correct answer:

Limits is correct. Limits are put in place to enforce a maximum on the amount of memory or processing a cloud customer can use. This can be done either on a virtual machine or as a comprehensive whole for a customer; it is meant to ensure that enormous cloud resources cannot be allocated or consumed by a single host or customer to the detriment of other hosts and customers.

A Type 2 hypervisor runs on top of another operating system and is dependent on the security of the OS for its own security. is correct. A Type 2 hypervisor differs from a Type 1 hypervisor in that it runs on top of another operating system rather than being directly tied into the underlying hardware of the virtual host servers. With this type of implementation, additional security and architecture concerns come into play because the interaction between the operating system and the hypervisor becomes a critical link. The hypervisor no longer has direct interaction and control over the underlying hardware, which means that some performance will be lost due to the operating system in the middle needing its own resources, patching requirements, and operational oversight.
