Which of the following is used primarily for archiving data?
Correct Answer: E
A Storage Area Network (SAN) is primarily used for data archiving and large-scale storage. SANs provide high-speed, block-level storage for enterprise environments. Why Not A (PAN): Personal Area Networks are for connecting personal devices like phones and smartwatches. Why Not B (MAN): Metropolitan Area Networks are for city-wide data communication, not storage. Why Not D (LAN): Local Area Networks are for general connectivity, not dedicated storage. Why Not WAN: Wide Area Networks are for connecting geographically dispersed networks, not storage. CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.7, network types and purposes.
Question 97
Which of the following should a company use to implement automatic time synchronization?
Correct Answer: C
NTP (Network Time Protocol) is specifically designed to synchronize the clocks of networked computers and devices automatically. From CompTIA A+ 220-1101 Official Study Guide, Objective 2.6 - Network services and protocols: "NTP is used to automatically synchronize system clocks on network devices, ensuring all systems have accurate time." Verified Source: * CompTIA A+ Core 1 (220-1101) Official Study Guide, Chapter 2: Networking Protocols * CompTIA Exam Objectives 220-1101, Domain 2.6
Question 98
A user routinely connects and disconnects multiple devices from a laptop. Which of the following options should a technician recommend to facilitate ease of user mobility?
Correct Answer: B
Reasoning: A docking station is designed to provide a central connection point for multiple peripherals, such as monitors, keyboards, mice, and network cables. It allows users to quickly connect or disconnect all devices by simply docking or undocking their laptop, improving mobility and reducing wear and tear on individual ports. Why the Other Options Are Incorrect: A: Serial interfaces: Serial interfaces are outdated and rarely used in modern laptops or peripherals. They are not practical for facilitating the connection of multiple devices. C: Network switch: A network switch is used to connect multiple devices to a network, but it does not simplify the connection of peripherals to a laptop. D: USB hub: A USB hub can extend the number of available USB ports but lacks the full functionality of a docking station, such as video output or Ethernet connectivity. Practical Example: A user with a laptop, external monitors, keyboard, and mouse can use a docking station to connect all devices with a single action, instead of plugging in each device manually. CompTIA A+ Exam Objective Alignment: Objective 5.2: Explain device interfaces, connection types, and usage of docking stations.
Question 99
Which of the following is designed to be used in commercial spaces?
Correct Answer: C
Plenum cabling is designed for use in commercial spaces where cables run through air ducts or plenum spaces, as it has fire-resistant properties and emits less toxic smoke. Why Not A (USB 3.1 Gen 2): USB is for peripheral connections, not large-scale commercial installations. Why Not B (Straight tip fiber connector): Fiber connectors are for high-speed connections but are not specifically for commercial spaces. Why Not D (Cat 8): While Cat 8 is high-speed, it is not uniquely suited for commercial spaces like plenum cabling. CompTIA A+ Exam Reference: Core 1 (220-1201), Section 3.1, cabling standards.
Question 100
Which of the following best represents the purpose of NFC?
Correct Answer: B
NFC (Near-Field Communication) is a subset of RFID technology designed for very short-range wireless communication, typically within a few centimeters. It is primarily used for contactless transactions, like mobile payments, and can also support peer-to-peer data exchanges. NFC operates at 13.56 MHz and enables devices to communicate when placed near each other.
