Correct Answer:
A
A serial interface is a common way to connect to the console port of a switch using a
rollover cable and a terminal emulator program. This allows the network technician to configure and troubleshoot the switch. Bluetooth, near-field communication, and port replicator are not used for console connections.

A technician is configuring the settings on a multifunction printer so the device can be shared across the LAN_ Which of the following should the technician do to enable the printer to be shared across the network?
Correct Answer:
B
To enable the printer to be shared across the network, the technician should configure the IP settings of the printer. The IP settings include the IP address, subnet mask, default gateway, and DNS server of the printer. The IP settings allow the printer to communicate with other devices on the network and access network resources such as print servers or cloud services.
The technician can configure the IP settings of the printer in different ways, such as:
✑ Using the printer’s control panel or web interface to manually enter the IP settings or obtain them automatically from a DHCP server.
✑ Using the printer’s software or driver to assign a static or dynamic IP address to the printer.
✑ Using a network discovery tool to find and configure the printer on the network. The technician should also make sure that the IP settings of the printer are compatible with the network configuration and do not cause any conflicts or errors.

A customer wants to archive a large number of photos and does not plan to retrieve them often. The customer wants a storage option that is the least expensive per gigabyte. Which of the following should the technician suggest?
Correct Answer:
D
The correct answer is D. 5,400rpm HDD.
A 5,400rpm HDD (Hard Disk Drive) is a type of storage device that uses spinning magnetic disks to store data. A 5,400rpm HDD is the least expensive per gigabyte among the options given, as it has a lower rotational speed and performance than other types of HDDs or SSDs (Solid State Drives). A 5,400rpm HDD is suitable for archiving a large number of photos that are not accessed frequently, as it can offer high capacity and reliability at a low cost.
the average cost per gigabyte of a 5,400rpm HDD is around $0.02 to $0.0312, while the average cost per gigabyte of the other options are:
✑ NVMe SSD: $0.10 to $0.1534
✑ SCSI RAID: $0.20 to $0.305
✑ 15,000rpm SAS: $0.30 to $0.40
Therefore, a 5,400rpm HDD is the cheapest option among the four. Reference: CompTIA A+ Core 1: RAM & Storage Solutions Flashcards

A user is requesting a headset that can be physically connected to a laptop for online conference calls. Which of the following connections should the headset use?
Correct Answer:
D
A USB (universal serial bus) connection is the most suitable option for a headset that can be physically connected to a laptop for online conference calls. A USB connection is a digital interface that can transfer both power and data between devices using a standard cable. A USB headset can plug into any available USB port on the laptop and communicate with the audio and microphone drivers without requiring additional software or hardware. A USB headset can also offer enhanced features, such as inline controls, noise cancellation, surround sound, or LED lighting, depending on the model and manufacturer.
Other connections, such as Bluetooth, DVI, or Thunderbolt, are not appropriate for a headset that can be physically connected to a laptop. Bluetooth is a wireless technology that uses radio waves to pair devices over a short distance, and it requires a battery or a charger for the headset. DVI (digital visual interface) is a video interface that can transmit digital or analog signals between a display device and a video source, and it is not compatible with audio or microphone devices. Thunderbolt is a high-speed interface that can support multiple protocols, such as DisplayPort, USB, or PCI Express, and it requires a special cable and port that may not be available on all laptops.
