質問112、 The IT department issued a corporate smartphone to a user, but the user returned the device stating it had connectivity Issues. The user claimed the device functioned on WI-FI but all connectivity to cloud services was lost as soon as the device was taken off site. Which of the following issues was MOST likely affecting the device?

MDM was never properly set up on the device.

S/MIME certificates were corrupted and needed to be reloaded.

Bluetooth on the device was disabled by mistake.

The device never had a proper SIM card installed.

Explanation
A SIM card is needed for the device to use cellular network services, so without it, the device will be unable to connect to the cloud services when taken off site. MDM (Mobile Device Management) can be used to manage settings and access on a device, but it is not necessary for the device to be able to use cloud services. S/MIME (Secure/Multipurpose Internet Mail Extensions) certificates are used to encrypt and digitally sign emails, and are not related to device connectivity. Bluetooth can be used to connect devices together, but it is not necessary for the device to be able to use cloud services.

質問114、 A technician is setting up a laptop with an encrypted hard drive. The laptop will securely store a PIN that the user will input at log-on. Which of the following must be installed to set up this configuration?

TPM

HSM

UEFI

ARM

Explanation
TPM stands for Trusted Platform Module, and it is a special chip installed on a computer’s motherboard that stores encryption keys, passwords, and digital certificates. It can also securely store a user’s PIN, allowing them to access the laptop without having to enter the PIN every time they log on. TPM is a secure way to store and protect sensitive data, making it ideal for use in laptops that need to securely store a PIN.

質問119、 A technician installed a Cat 5 UTP cable approximately 275ft (84m) from a network switch in an office to a workstation located on a factory floor The technician sees both a flashing green LED and a flashing orange LED on the workstation’s NIC. Which of the following should the technician do FIRST?

Check for loose connections, pinched bends, and physical damage.

Install a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run.

Replace the entire run of Cat 5 UTP cable with Cat 5 STP cable.

Upgrade the entire cable run to multimode fiber.

The flashing green and orange LEDs on the NIC indicate connection issues. The technician should first check for loose connections, pinched bends, and physical damage, which are the most common causes of connection problems. Reference: CompTIA A+ Certification Exam Guide, Ninth Edition, Chapter 14

質問120、 Which of the following network devices is used to separate broadcast domains?

Switch

Wireless access point

Router

Hub

A router (option C) is a network device that is used to separate broadcast domains. A broadcast domain is a logical division of a computer network in which all nodes can reach each other by broadcast at the data link layer. Routers operate at the network layer of the OSI model and use routing tables to determine the best path for forwarding packets between different networks.
By separating broadcast domains, routers can help to reduce network congestion and improve performance. When a router receives a broadcast packet on one of its interfaces, it does not forward the packet to any other interfaces. This means that only devices within the same broadcast domain as the sender will receive the broadcast packet.

質問121、 A technician wants to deploy a .msl package lo a corporate network. The technician needs to verily the application deployment will not affect other legacy applications on the end users’ computers. Which of the following would the technician consider the MOST appropriate for this situation?

質問122、 A user is unable to plug a USB 3.0 device into a USB port. Upon inspection, a technician notices the USB 3.0 port appears to be slightly smaller than the other connections. Which of the following Is the MOST likely cause?

A foreign object Is stuck Inside the port

The cable connection utilized the wrong orientation.

The USB cable is physically damaged.

The USB port belongs to a different form factor.

USB 3.0 ports are slightly smaller than other USB connections, so if the port appears to be the wrong size, it is likely that the port belongs to a different form factor. This can be caused by a number of factors, such as the device being too old to support USB 3.0, or the device not having a USB 3.0 port in the first place.

質問123、 A technician is replacing a computer with a connected point-of-sale system using a 9-pin serial adapter. The new computer does not have a 9-pin serial port. Which of the following ports can an adapter be installed on in order to connect to the point-of-sale system?

HDMI

Bluetooth

USB

Lightning

A USB to 9-pin serial adapter can be used to connect the new computer to the point-of-sale system using a USB port. USB is a common and versatile port type found on most computers.
If a technician is replacing a computer with a connected point-of-sale system using a 9-pin serial adapter and the new computer does not have a 9-pin serial port, an adapter can be installed on the USB port in order to connect to the point-of-sale system. A USB-to-serial adapter can be used to connect a serial device to a USB port on a computer.

Which of the following should be upgraded FIRST?

SSD

CPU

HDD

RAM

The component that should be upgraded first is the RAM. When multiple applications are being utilized, the system’s response time slows down drastically. This is because the computer is running out of memory. Upgrading the RAM will allow the computer to store more data in memory, which will improve performance when multiple applications are being used123.
