• Question 191:

  Each floor at a new corporate facility will have four printers available for all users to print from AH of the printers will be connected with RJ45 and not joined to a domain.

  Which of the following needs to be set up to accomplish this task? (Select two).

  A. Printer shares
  B. DHCP server
  C. Print server
  D. Printer subnet
  E. SMB configuration
  F. Printer Wi-Fi settings
  A. Printer shares
  C. Print server

  ---

  Explanation

  To allow multiple users to print to networked printers:

  Printer shares enable users to access printers shared on the network.

  Print servers manage print jobs and provide centralized control of printing.

  Why Not B (DHCP server): DHCP is unrelated to print management.

  Why Not D (Printer subnet): Subnets group devices but don't manage printing.

  Why Not E (SMB configuration): SMB is for file sharing, not specifically print management.

  Why Not F (Printer Wi-Fi settings): These settings are irrelevant since the printers use Ethernet.

• Question 192:

  Which of the following is the standard for Wi-Fi 7?

  A. 802.1X
  B. 802.3at
  C. 802.11be
  D. 802.15.1
  C. 802.11be

  ---

  Explanation

  The IEEE standard for Wi-Fi 7 is 802.11be, also known as Extremely High Throughput (EHT). According to CompTIA Core 1 (220-1201) networking standards objectives, each Wi-Fi generation corresponds to a specific IEEE 802.11 amendment. Wi-Fi 7 builds upon Wi-Fi 6/6E by offering significantly higher throughput, lower latency, and improved performance in high-density environments.

  Option 802.11be is the only choice that represents a wireless LAN (WLAN) standard. 802.1X is an authentication framework used for network access control, not a Wi-Fi standard. 802.3at defines Power over Ethernet Plus (PoE+), which supplies electrical power over Ethernet cables. 802.15.1 is the IEEE standard for Bluetooth.

  CompTIA expects candidates to recognize and differentiate wireless standards and their IEEE designations, especially newer technologies such as Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7. Identifying 802.11be as Wi-Fi 7 is essential for both exam success and real-world networking scenarios.

• Question 193:

  After moving a user's legacy workstation into a new private office that does not have a LAN connection, the technician is unable to connect to a wireless network.

  Which of the following is the most likely reason?

  A. Missing Wi-Fi adapter
  B. Wi-Fi AP replacement
  C. Hidden Wi-Fi SSID
  D. Incorrect Wi-Fi channel
  A. Missing Wi-Fi adapter

  ---

  Explanation

  The most likely reason is A. Missing Wi-Fi adapter. A Wi-Fi adapter is a device that allows a computer to connect to a wireless network. A legacy workstation may not have a built-in Wi-Fi adapter, or it may have an outdated or incompatible one. If the workstation does not have a Wi-Fi adapter, it will not be able to detect or access any wireless networks, regardless of the location, signal strength, or configuration of the network. To fix this issue, the technician can install a Wi-Fi adapter on the workstation, either internally or externally. An internal Wi-Fi adapter is a card that fits into a slot on the motherboard, while an external Wi-Fi adapter is a device that plugs into a USB port. The technician should choose a Wi-Fi adapter that is compatible with the workstation's operating system, hardware, and wireless standards . The other options are less likely to be the reason for the issue. A Wi-Fi AP replacement means changing the wireless access point that provides the network connection. This may affect the network name, password, or settings, but it should not prevent the workstation from detecting any wireless networks. A hidden Wi-Fi SSID means that the network name is not broadcasted publicly, but it can still be accessed by entering the name manually. A hidden Wi-Fi SSID may make it harder to find the network, but it should not prevent the workstation from detecting other wireless networks. An incorrect Wi-Fi channel means that the network is using a frequency band that is crowded or interfered by other devices. This may affect the network performance or stability, but it should not prevent the workstation from detecting any wireless networks.

  A user is receiving many unsolicited emails.

  Which of the following controls can be configured to best reduce these types of emails?

  A. Load balancer
  B. Spam gateway
  C. Mail forwarding
  D. Proxy servers
  B. Spam gateway

  ---

  Explanation

  A spam gateway filters unsolicited emails at the server level, significantly reducing spam before it reaches user inboxes.

  Why Not A (Load balancer): Load balancers distribute traffic but don't filter spam.

  Why Not C (Mail forwarding): Forwarding doesn't filter spam.

  Why Not D (Proxy servers): Proxies control web traffic, not email filtering.

• Question 196:

  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?

  A. Serial interfaces
  B. Docking station
  C. Network switch
  D. USB hub
  B. Docking station

  ---

  Explanation

  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:

  Option 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.

  Option 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.

  Option 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.

• Question 197:

  A technician has discovered that some users are connected to a network that is not available on the user interface.

  Which of the following is the most effective tool the technician can use to identify networks that are not broadcasting SSIDs?

  A. Cable tester
  B. Toner probe
  C. Wi-Fi analyzer
  D. Loopback plug
  C. Wi-Fi analyzer

  ---

  Explanation

  Wi-Fi Analyzer:

  A Wi-Fi analyzer is a tool used to detect and analyze wireless networks, even those that are not broadcasting their SSIDs (hidden networks).

  It provides detailed information about nearby networks, including signal strength, channel usage, and security protocols.

  In this case, the Wi-Fi analyzer can identify the hidden networks that users are connected to, which are not visible on the standard user interface.

  Incorrect Options:

  Option A: Cable tester: A cable tester is used to test the integrity of physical network cables. It does not detect wireless networks or SSIDs.

  Option B: Toner probe: A toner probe is used to trace and identify cables within a wiring system. It is not applicable to wireless network analysis.

  Option D: Loopback plug: A loopback plug is used to test the functionality of a network port or NIC. It is unrelated to identifying hidden wireless networks.

  Key Takeaway:

  The most effective tool for identifying hidden wireless networks is a Wi-Fi analyzer, as it can detect networks that are not broadcasting their SSIDs.

• Question 198:

  A customer reports slow network speeds.

  Which of the following components is most likely failing?

  A. CPU
  B. NIC
  C. HDD
  D. RAM
  B. NIC

  ---

  Explanation

  A Network Interface Card (NIC) is the hardware responsible for network connectivity. If the NIC is failing or underperforming (e.g., due to a bad driver, hardware fault, or misconfiguration), it can causeslow or unstable network speeds.

  Option A (CPU):A failing CPU affects overall system performance but not specifically network speed.

  Option C (HDD):A slow hard drive causes application lag, but not poor network performance.

  Option D (RAM):Affects multitasking and speed, not network throughput.

• Question 199:

  A user receives an error when installing a new email app on their phone. Technician verifies OS is updated and app is supported.

  What should the technician check next?

  A. Storage
  B. Battery health
  C. SIM card
  D. Processor
  A. Storage

  ---

  Explanation

  When an application fails to install on a smartphone despite being supported by the OS and device type, CompTIA A+ stresses that the most common cause is insufficient storage. Mobile devices require not only space for the app itself but also additional temporary space for the installation process, cached data, and updates. If internal storage is nearly full, the app store will display installation errors--even if the OS and hardware meet requirements.

  Battery health has no impact on app installation. A SIM card is unrelated to installing local applications--it only affects cellular connectivity. Processor architecture issues would have been caught during compatibility checking, but the technician already verified the device supports the application.

  Therefore, after confirming compatibility, the next logical step is to check available storage space. If storage is low, deleting unused apps, clearing cached data, or transferring media to cloud storage or an SD card typically resolves the installation issue.

  Thus, Option A: Storage is the correct answer.

• Question 200:

  Which of the following is primarily used to connect different networks?

  A. Controller
  B. Bridge
  C. Hub
  D. Router
  D. Router

  ---

  Explanation

  The correct answer is D. Router.

  According to the CompTIA A+ Core 1 (220-1201) objectives for Networking, routers are devices that operate at Layer 3 (Network layer) and are primarily used to connect multiple networks, including LANs, WANs, and the Internet. Routers use IP addressing to determine the best path for forwarding packets between networks.

  Why the other options are incorrect:

  A. Controller: Generally refers to a device that manages a network or hardware component but does not inherently connect different networks.

  B. Bridge: Connects two segments of the same network, not different networks, and operates at Layer 2 (Data Link layer).

  C. Hub: Connects devices within the same network segment, simply repeating signals, and does not perform routing between networks.
