Why can cache improve performance?

• It increases the CPU processing power.

• It reduces the data access time from main memory.

• It provides additional storage space.

• It enhances the graphics quality.

Answer explanation

It reduces the data access time from main memory.

Is it advisable to use a Xeon E3-1231 CPU in a multi-socket motherboard that also uses the LGA 1150, considering symmetric multiprocessing and system performance upgrade?

• Yes, because it supports symmetric multiprocessing.

• No, because it does not support symmetric multiprocessing.

• Yes, because it enhances the graphics processing.

• No, because it is incompatible with LGA 1150.

Answer explanation

No, because it does not support symmetric multiprocessing.

Can any x64-compatible CPU with sufficient clock speed be used for a software development workstation that runs multiple virtual machines?

• Yes, if it also supports hyper-threading.

• No, it must also support virtualization technology.

• Yes, as long as the clock speed is sufficient.

• No, it must be a specific model recommended for virtualization.

Answer explanation

Yes, as long as the clock speed is sufficient, any x64-compatible CPU can be used for a software development workstation running multiple virtual machines.

What must you check when inserting a PGA form factor CPU?

• The compatibility with the motherboard socket.

• The power supply wattage.

• The type of cooling system installed.

• The brand of the CPU.

Answer explanation

The compatibility with the motherboard socket must be checked to ensure the PGA form factor CPU fits correctly.

What should be checked when provisioning Power Supply Units (PSUs) for system devices?

• Color and size of the PSU

• Input voltage and wattage rating

• Brand and warranty period

• Number of connectors available

Answer explanation

Input voltage and wattage rating should be checked when provisioning Power Supply Units (PSUs) for system devices to ensure compatibility and proper power supply.
