a) Data migration
b) Trimming
c) Wear leveling
d) Caching
Correct Answer: b) Trimming
Explanation: Trimming helps maintain the performance of SSDs by organizing data and minimizing fragmentation on the drive.
Question 08
What does SMART technology do?
a) Increases data transfer rates
b) Predicts when a drive is likely to fail
c) Enhances graphic performance
d) Manages network traffic
Correct Answer: b) Predicts when a drive is likely to fail
Explanation: SMART (Self-Monitoring, Analysis, and Reporting Technology) monitors various metrics to alert users of potential drive failures.
Question 09
What technique ensures that logical block addressing does not always address the same physical blocks in an SSD?
a) Trimming
b) Caching
c) Wear leveling
d) Data migration
Correct Answer: c) Wear leveling
Explanation: Wear leveling distributes write and erase cycles across the memory blocks of an SSD to prolong its lifespan and improve reliability.
Question 10
Which type of storage devices are characterized by the fastest access times and data transfer rates?
a) Hard Disk Drives (HDDs)
b) Optical Drives
c) Solid-State Drives (SSDs)
d) Tape Drives
Correct Answer: c) Solid-State Drives (SSDs)
Explanation: SSDs provide significantly faster access and transfer speeds due to their use of flash memory and lack of moving parts.
Question 11
What is data migration?
a) The process of deleting unnecessary files
b) The process of transferring data between storage types, formats, or computer systems
c) The process of backing up data
d) The encryption of data for security
Correct Answer: b) The process of transferring data between storage types, formats, or computer systems
Explanation: Data migration involves moving data from one system or format to another, often during upgrades or system changes.
Question 12
What does the PCIe standard refer to?
a) A type of RAM
b) A high-speed serial computer expansion bus standard
c) A network protocol
d) A type of optical drive
Correct Answer: b) A high-speed serial computer expansion bus standard
Explanation: PCIe (Peripheral Component Interconnect Express) is designed to replace older bus standards with a faster and more efficient interface for connecting hardware.
Question 13
What is thick-client computing?
a) A model where the server performs all processing
b) A client-server model where the client performs the majority of processing
c) A method for cloud-based computing
d) A type of thin client
Correct Answer: b) A client-server model where the client performs the majority of processing
Explanation: Thick-client computing places most processing responsibilities on the client, often requiring significant local resources.
Question 14
What are internal shared resources in cloud computing?
a) Resources that are only accessible to individual users
b) Resources such as servers and applications shared among people within an organization
c) Publicly available cloud services
