질문 # 71
Which type of conversion involves turning off the old system and turning on the new system at a particular date and time?
정답:B
설명:
In this approach, users stop using the old system, and the new system is put into use immediately1. However, direct conversion can be risky, especially without extensive testing beforehand2.

질문 # 72
Which motherboard component is used for short-term storage of data?
정답:B
설명:
*RAM (Random Access Memory) is the motherboard component used for short-term storage of data.
*RAM is a type of computer memory that can be read and written. It serves as temporary storage for data that the CPU (Central Processing Unit) needs to access quickly.
*When you run programs or open files, the data is loaded into RAM from storage devices (such as hard drives or SSDs). The CPU can then access this data rapidly, allowing for efficient execution of tasks.
*Unlike permanent storage (such as hard drives), RAM is volatile, meaning its contents are lost when the computer is powered off or restarted.
*RAM is crucial for overall system performance. The more RAM a computer has, the better it can handle multitasking, large applications, and data-intensive tasks.
*In summary, RAM provides fast, temporary storage for data that the CPU actively uses during program execution.

질문 # 73
What is the goal in improving uptime?
정답:B
설명:
The goal of improving uptime is increasing the portion of time for which systems are operational. In Information Technology operations and service management, uptime measures availability, meaning how consistently an information system is running and accessible when users need it. High uptime is critical for business continuity, customer satisfaction, and meeting service level agreements. Improving uptime involves reducing both planned downtime, such as maintenance windows, and unplanned downtime, such as hardware failures, software crashes, network outages, or cyberattacks. Common strategies include redundancy, failover clustering, monitoring and alerting, preventative maintenance, patch management, and resilient infrastructure design. Increasing time between maintenance events can contribute indirectly, but it is not the definition of uptime improvement. Faster startup processes may reduce downtime duration during restarts, but it is only one factor. Increasing the interval between backups could actually increase risk and does not improve availability. Since uptime is fundamentally the percentage of time systems remain available and functioning, the correct objective is to increase the portion of time the systems are operational. Therefore, the correct answer is option D.
질문 # 74
Which type of network is used to connect wireless headphones to a smartphone?
정답:D
설명:
Wireless headphones typically connect to a smartphone using Bluetooth, which is an example of a personal area network. In Information Technology, a personal area network is a short-range network centered around an individual's devices, usually within a few meters. PAN technology is designed for low power usage and convenient device pairing, making it ideal for accessories such as headphones, smartwatches, fitness trackers, and wireless keyboards. A local area network covers a larger area such as a home, office, or campus and commonly uses Ethernet or Wi-Fi to connect computers and network devices. A wide area network spans large geographic distances and connects networks across cities, countries, or continents, often using leased lines or internet infrastructure. Extended area network is not a standard category used in most networking fundamentals curricula compared with PAN, LAN, MAN, and WAN. Since the connection between headphones and a phone is short-range and personal, it is best classified as a personal area network.
Therefore, the correct answer is PAN.
질문 # 75
Which type of services are Google Apps, Dropbox, and GoToMeeting?
정답:B
설명:
Google Apps, Dropbox, and GoToMeeting are all examples of Software-as-a-Service (SaaS). SaaS is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the internet. This contrasts with IaaS, which provides virtualized computing resources over the internet, and PaaS, which offers hardware and software tools over the internet.
1.Google Apps (now Google Workspace) provides productivity and collaboration tools.
2.Dropbox offers cloud storage and file synchronization services.
3.GoToMeeting is an online meeting, desktop sharing, and video conferencing software.
All three services are accessed over the internet and do not require users to manage hardware or software updates, which is characteristic of the SaaS model.
References: The information is verified by multiple sources that discuss cloud service models, including articles that specifically categorize Google Workspace, Dropbox, and GoToMeeting as SaaS12. Additionally, Google's support documentation for GoToMeeting integration with Google Workspace further supports this classification3.
