Question # 1
Which of the following provides the highest level of isolation from the host operating system?
✑ Type Il hypervisor
✑ Resource pooling
✑ Hardware-assisted virtualization
|
| A. Single-node clustering |
A. Single-node clustering
Explanation: A type II hypervisor is a software application that runs on top of a host operating system and creates virtual machines that are isolated from the host. A type II hypervisor provides the highest level of isolation from the host operating system because it does not have direct access to the hardware resources and relies on the host operating
system for drivers and services. A type II hypervisor also allows the guest operating systems to run different types of operating systems than the host.

Question # 2
| A bank wants to leverage cloud computing but would like a cloud solution in which
infrastructure is shared with businesses in the same industry. Which of the following cloud
models would BEST address the bank's need? |
| A. Private | | B. Hybrid | | C. Public | | D. Community |
D. Community
Explanation: A community cloud model is a cloud solution in which infrastructure is shared
among organizations that have common interests, goals, or concerns, such as security,
compliance, or industry standards. This model would best address the bank’s need to
leverage cloud computing while maintaining a high level of security and privacy for its data
and transactions. The other cloud models are not suitable for this scenario, as they either
do not offer enough control over the infrastructure (public cloud), or do not allow for sharing
of resources among similar organizations (private cloud and hybrid cloud).
Question # 3
| A cloud engineer, who is designing a cloud architecture, needs to ensure the solution is able to immediately fail over to another region in case of an outage and also scale up in the event of high utilization. Which of the following should the engineer Implement? (Select two). |
| A. High availability | | B. Elasticity | | C. Cold storage | | D. Machine learning | | E. Metered utilization |
A. High availability
B. Elasticity
Question # 4
| An administrator is replacing a cable that uses a DB9 connector VVhich of the following cables is the administrator replacing? |
| A. Parallel | | B. Serial | | C. Optical | | D. USB |
B. Serial
Question # 5
An engineer is building a workstation that requires the following components:
-
An ATX motherboard
- A multi-core processor
- A dedicated graphics solution
- A SATA hard drive
- DDR4 memory
Which of the following power supply specifications would meet the workstation criteria? |
| A. 12V, 500W output | | B. SFX, 18-pin connector | | C. DC input | | D. Type A socket |
A. 12V, 500W output
Explanation: A power supply unit (PSU) is a component that converts AC power from the
wall outlet to DC power that can be used by the computer components. A PSU has various
specifications, such as input voltage, output voltage, wattage, connector type, form factor,
and efficiency rating3. In this scenario, the engineer is building a workstation that requires
the following components: an ATX motherboard, a multi-core processor, a dedicated
graphics solution, a SATA hard drive, and DDR4 memory. The most suitable power supply
specification for this workstation is 12V, 500W output. This means that the PSU can
provide 12 volts of DC power and 500 watts of total power to the components. 12V is the
standard output voltage for most modern PSUs, and it is compatible with the ATX
motherboard and the SATA hard drive4. 500W is a sufficient wattage for a workstation that
has a multi-core processor and a dedicated graphics solution, which are power-hungry
components5. The other power supply specifications are not suitable for this workstation
because:
- SFX, 18-pin connector is a form factor and a connector type that are not compatible with
the ATX motherboard, which requires an ATX form factor and a 24-pin connector6.
- DC input is a type of input voltage that is not common for desktop PSUs, which usually
use AC input from the wall outlet.
- Type A socket is a type of AC power plug that is used in North America and Japan, but it
is not a power supply specification.
