An IT Administrator noticed that the company needed a more secure way to create and store operating system licensing data. What should the IT Administrator implement?
TPM (Trusted Platform Module) - a hardware based storage of digital certificates, cryptographic keys, and hashed passwords
A system administrator implemented a physical device that expedites cryptographic operations and manages cryptographic keys. What device has the system administrator implemented?
HSM (Hardware Security Module) - a secure USB key or thumb drive used to store cryptographic material
A technician replaced a failed hard drive in a RAID array and noticed a severely degraded performance. What is the problem?
Rebuilding the array consumes many resources. The performance of the array degrades for some time since the array is rebuilding and the system is writing several gigabytes of data onto the new drive.
After running a SMART diagnosis on a computer, with extended read/write times, the input/output per second (IOPS) matches the vendor’s baseline. What could be the problem?
Limited hardware drive (storage) capacity. If the IOPS matches the vendor baseline, the technician must address other problems such as a hard drive nearly at capacity.
A RAID array cannot boot, and the technician cannot reach the configuration utility. There have been no recent changes to the array. What is the likely problem?
Controller failure. The first step in troubleshooting the problem is to use the configuration utility to verify the status. If the system cannot reach it, the the controller likely failed.
How can a technician diagnose capacitor swelling?
Physical inspection. Capacitors are barrel-like components that regulate the flow of electricity to system chips. Swollen, bulging, or emitting any residue indicates damaged or failed capacitors. The only way to diagnose this is visual.
What type of memory relies on temporary storage space on the hard drive that is used when there is insufficient physical memory available to perform a given task?
Virtual memory
You boot up a desktop computer you installed and smell a foul-smelling chemical odor. You sniff the air again and determine it isn’t a burning smell. Upon opening the case, which component should you inspect for damage and expect to replace?
Motherboard
Which motherboard form factor measures 6.7” x 6.7” (17cm x 17cm) in size?
mITX
Which optical disc type can only support up to 700MB on a single piece of media?
CD-RW
Which connection type would be the BEST choice for tethering a smartphone to a laptop when a stable, secure, high-speed internet connection is required?
A) Wi-fi Hotspot
B) NFC
C) Bluetooth
D) USB
USB
Which of the following is a proprietary wireless communication protocol operating in the 800MHz to 900MHz frequency band and is primarily used for home automation?
A) Zigbee
B) NFC
C) Z-Wave
D) Bluetooth
Z-Wave (Zigbee operates at the 2.4GHz band.)
Which key do you press to enter the boot order menu?
F12
What are 3 aspects of a boot password?
1) Primarily protects against unauthorized use of the device
2) Required before the OS loads to prevent unauthorized access
3) Does not restrict access to BIOS/UEFI settings
What does NOT apply to a BIOS password?
Ensures that unauthorized users cannot start the system.
A set of Intel CPU hardware enhancements that enable virtualization is known as…
VT-x
What are the characteristic features of a TPM?
1) Typically embedded directly into consumer devices
2) Provides security that is specifically tied to a single device
3) Offers basic cryptographic functions, such as key storage and platform integrity support
What are the characteristic features of HSM?
1) Designed for centralized cryptographic keys management, supporting high volumes of cryptographic operations
2) Supports multiple devices, users, and systems across a network, not tied to a single device
3) Can be a dedicated network-attached appliance, a PCIe card, or a USB device
What term refers to 32-bit CPU architecture?
x86
What is the standard voltage range used for power outlets in Europe?
220-240 VAC
What is a key characteristic of a Type I hypervisor?
It runs directly on the host hardware, providing better performance and efficiency.
Which mobile device accessory includes a small, pressure-sensitive nub that is commonly used as a pointing device for laptops?
Track point
A computer technician is building a server that will run multiple virtual machines simultaneously. Which CPU technology should be selected so that the processor can utilize two LOGICAL cores?
Hyperthreading
A computer technician is building a server that will run multiple virtual machines simultaneously. Which CPU technology should be selected so that the processor can utilize two PHYSICAL cores?
