1. Brian has built a private cloud in his company's data center. He has just racked up a server and turned it on for
the first time. Which of the following extensions might he see that he should ensure are enabled in the
UEFI/BIOS setup before continuing to install the operating system and configure the server to be part of the
private cloud? (Choose two.)
a. Intel-V
b. VT-x
c. AMD-V
d. AV-x
ANSWER: c
FEEDBACK: a. Incorrect. The Intel extension would be the VT-x extension. There is also a VT-i
extension for the Itanium line of processors, but there is no Intel-V.
b. Correct. The VT-x and VT-i extensions are possibilities you might see for the Intel
architecture.
c. Correct. The AMD-V extension is used for the AMD architecture.
d. Incorrect. There is no AV-x extension for hardware-assisted virtualization.

2. Henry has just been hired as a security engineer and has been tasked with analyzing the cloud infrastructure
that the company uses. Which of the following might Henry be concerned about if he discovers that critical data
is being stored in that environment?
a. Shared compute
b. Dedicated compute
c. High availability
d. Cluster
ANSWER: a
FEEDBACK: a. Correct. A shared compute environment means that other tenants or companies share
resources with Henry's company. This means that there could be bugs or vulnerabilities
that could potentially let one tenant see the information and data from another tenant.
This is a potential risk to the critical data, which Henry needs to ensure is protected.
b. Incorrect. A dedicated compute environment means that Henry's company is the only one
using that computing environment. This is more secure than a shared compute
environment.

c. Incorrect. High availability is the concept that a service should remain available a large
percentage of the time. However, these setups can be configured as a shared or
dedicated computer environment.
d. Incorrect. A cluster is a group of devices, computers, or servers that work together.
These can be deployed to offer shared compute or dedicated compute environments.

3. Frank is configuring a virtual machine that will reside on a CSP's infrastructure that will eventually need
multiple terabytes of storage for data. However, he decides to only configure it with one terabyte in the
beginning and then provision more disk space as necessary. Which of the following is the most likely reason for
his decision?
a. Obsolescence
b. Fragmentation
c. Incompatibility
d. Cost
ANSWER: d
FEEDBACK: a. Incorrect. Technology continuously evolves, and what is current today may be obsolete
next year. However, this does not impact storage sizing solutions for a product where you
pay as you go, such as using a cloud service provider.
b. Incorrect. While data can become fragmented on virtual disks being used by virtual
machines, this would not be a reason why he would only provide what is necessary for
the beginning stages of this project.
c. Incorrect. The cloud provider should only continue to offer services and allow Frank to
choose services that are compatible with each other. If the type of storage he has chosen
initially is no longer compatible, he should be able to go through a migration process to
whatever the replacement service or technology is.
d. Correct. In this scenario, the cloud provider most likely charges for the space that has
been provisioned and reserved for the customer, not necessarily the space that is
actually used.

4. Margaret has designed an application and the underlying systems that it resides on to have a five-nine uptime
or 99.999%. Which of the following techniques has she implemented?
a. Shared compute
b. High availability
c. Disaster recovery
d. Overcommitment
ANSWER: b
FEEDBACK: a. Incorrect. Shared compute is the idea that multiple virtual machines can share the same
processing power. While these systems can certainly be deployed using shared
compute, they cannot be completely determined from the scenario given.
b. Correct. High availability is the term used to describe systems that are designed with very
high uptimes with very minimal downtime. There are multiple techniques that can be
used to deliver applications with high availability.
c. Incorrect. While systems that implement high availability typically have a disaster
recovery plan, they are a bit different. With disaster recovery, the goal is to recover from
the failure as quickly as possible, whereas, with high availability, the goal is to stay
available even when there is a failure.
d. Incorrect. An over-commitment ratio can be used to allocate more vCPUs on a host than
logical cores or to allocate more memory than is physically available. It is not necessarily
a technique that would be used to describe high availability.

5. Chris has discovered a technique for assisting with memory allocation that he can configure on some of his
virtualized systems. Using this method, a driver is installed on each of a host's virtual machines. This driver
enables the host to control a bogus process on the virtual machine, causing the VM to allocate memory to that

process. Rather than using the memory that has been allocated to the process, the host can assign it to another
virtual machine so that it can use it instead. Which of the following best describes the memory reclamation
process that Chris is thinking about using?
a. Ballooning
b. Overcommitment
c. Bursting
d. Hyperthreading
ANSWER: a
FEEDBACK: a. Correct. Ballooning is a technique that installs a driver from the host onto the virtual
machine so that the VM can allocate memory to a process that the host has control over.
That memory can then be reallocated by the host to a different virtual machine.
b. Incorrect. Overcommitment is the idea that you can allocate multiple vCPUs per logical
thread or more total memory on the virtual machines combined than on the physical host.
c. Incorrect. Bursting is the idea that a system may only need a certain amount of memory
on average for most of its tasks but has the ability to burst up to a certain amount when
needed.
d. Incorrect. Hyperthreading is the ability of an Intel CPU to schedule two series of tasks at
one time so that a single physical core appears to have two logical cores.

6. Jana is trying to optimize the cloud infrastructure of her organization for availability. She wants to ensure that
the virtual machines that normally use a certain amount of memory can use more physical memory up to a
predefined level in cases of heavy workloads. Which of the following features should she look at configuring?
a. Overcommitment
b. Ballooning
c. Hyperthreading
d. Bursting
ANSWER: d
FEEDBACK: a. Incorrect. While the overcommitment of memory can help optimize the cloud
infrastructure, the scenario specifically states that the goal is availability. In this case,
bursting is the best answer when looking to expand the resources available on the fly.
