Actual exam question for LPI's 304-200 exam

Question #: 89
Topic #: 9

Which of the following statements are true regarding resource management for full virtualization? (Choose TWO correct answers.)

AThe hypervisor may provide fine-grained limits to internal elements of the guest operating system such as the number of processes.

BFull virtualization cannot pose any limits to virtual machines and always assigns the host system's resources in a first-come-first-serve manner.

CIt is up to the virtual machine to use its assigned hardware resources and create, for example, an arbitrary amount of network sockets.

DThe hypervisor provides each virtual machine with hardware of a defined capacity that limits the resources of the virtual machine.

EAll processes created within the virtual machines are transparently and equally scheduled in the host system for CPU and I/O usage.

I'm gonna have to go with C. The DLM is the distributed lock manager, and OCFS2 definitely needs that to coordinate access to the shared filesystem. Piece of cake!

Haha, this question is a bit of a trick! The answer is clearly E. The O2CB service is like the heart and soul of OCFS2, how could that not be required?

D is the answer, for sure. The CLVM is used for managing cluster-wide logical volumes, but OCFS2 doesn't need that. It has its own ways of handling the shared storage.

Yeah, CLVM is not required for OCFS2 to run in a Pacemaker cluster.

Hmm, I'm not sure about this one. Maybe B is the answer? Shared storage is a must-have for OCFS2, right? Or is that too obvious...

E is the correct answer. The O2CB service is not a required component for OCFS2 in Pacemaker. It's used for cluster communication, but not essential for the filesystem itself.
