A customer recently lost data due to several unexpected shutdowns. Data integrity is important to the customer. Which of the following features should the technician choose to prevent data loss?
A. Redundant power supply
B. Uninterruptible power supply
C. Modular power supply
D. High-efficiency power supply
Show Answer
Correct Answer: B
Explanation: An uninterruptible power supply (UPS) provides battery backup during power outages and brief interruptions, allowing the system to continue running long enough to save work and perform a graceful shutdown. This directly prevents data loss from unexpected shutdowns. A redundant power supply improves availability in systems with dual PSUs but does not protect against utility power loss by itself. Modular and high-efficiency power supplies do not address unexpected power interruptions.
Question 102
A technician sets up secure print and configures an NFC device that will authenticate users for access. Which of the following will the NFC device most likely use to authenticate?
A. Badging
B. Password
C. Passcode
D. Biometrics
Show Answer
Correct Answer: A
Explanation: NFC-based authentication for secure print commonly uses a proximity badge or smart card. The user taps an NFC-enabled ID badge or credential to authenticate, making this a possession-factor authentication. Passwords, passcodes, and biometrics are different authentication methods and are not what the NFC device itself most likely uses in this scenario.
Question 103
A user purchases a new mobile phone and tries to connect it to the corporate communications and email applications without success. Which of the following should a technician do to allow the phone to connect?
A. Configure biometric security settings
B. Turn on LTE hotspot connectivity
C. Enroll the device in the MDM software.
D. Complete the company's BYOD training process
Show Answer
Correct Answer: C
Explanation: Corporate email and communication applications commonly require devices to be enrolled in the organization's Mobile Device Management (MDM) platform before access is granted. MDM enforces security policies, provisions corporate apps and certificates, and verifies device compliance. Biometric settings, LTE hotspot functionality, and BYOD training alone do not enable the device to connect to managed corporate services.
Question 104
A company migrates a local application to an internal cloud platform. Which of the following best describes this cloud platform?
A. Private
B. Public
C. Community
D. Hybrid
Show Answer
Correct Answer: A
Explanation: An internal cloud platform dedicated to a single organization is a private cloud. Public clouds are shared and operated by third-party providers, community clouds are shared among organizations with common needs, and hybrid clouds combine two or more cloud deployment models.
Question 105
Which of the following display technologies typically provides the highest contrast?
A. IPS
B. OLED
C. TN
D. VA
Show Answer
Correct Answer: B
Explanation: OLED displays are self-emissive, allowing individual pixels to turn completely off and produce true blacks. This yields the highest perceived and measured contrast ratio (often described as effectively infinite) compared with LCD technologies such as IPS, TN, and VA, which rely on a backlight.
Question 106
Which of the following networking devices is used to create a mesh network?
A. Modem
B. DSL
C. Access point
D. ONT
Show Answer
Correct Answer: C
Explanation: A mesh network is built using multiple wireless access points (mesh APs or mesh nodes) that communicate with one another to extend coverage. A modem provides WAN connectivity, DSL is an access technology rather than a device, and an ONT terminates a fiber connection; none of these create a mesh network.
Question 107
A technician is setting up a new multifunction device to be used over a shared network connection. Copier functions need to be restricted to only office employees. Which of the following should the technician perform after configuring the device to use a print server that exists on the domain?
A. SMTP implementation
B. Firmware update
C. User authentication
D. SMB configuration
Show Answer
Correct Answer: C
Explanation: User authentication allows the multifunction device to identify users (for example, via domain credentials, PINs, or badges) and enforce access controls so only authorized office employees can use copier functions. SMTP is for email, firmware updates improve software but do not implement access restrictions, and SMB provides file-sharing/network access rather than user-based copier authorization.
Question 108
A company deploys its infrastructure in self-operated data centers. The company recently migrated some of its applications to a public cloud. Which of the following most accurately describes the cloud model the company is following?
A. Public
B. Hybrid
C. Community
D. Private
Show Answer
Correct Answer: B
Explanation: A hybrid cloud combines on-premises (self-operated data centers or private infrastructure) with public cloud services. Because the company continues to operate its own data centers while also running some applications in a public cloud, it is using a hybrid cloud model.
Question 109
A technician is setting up a new SOHO wireless router. According to security best practices, which of the following should the technician do first?
A. Enable encryption.
B. Assign a static IP.
C. Change the default password.
D. Reset the router.
Show Answer
Correct Answer: C
Explanation: The first security best practice when setting up a new SOHO wireless router is to change the default administrative password. Default credentials are widely known and can allow unauthorized access to the router's configuration. After securing administrative access, the technician should then enable strong wireless encryption and complete the remaining configuration.
Question 110
A multifunction printer in a small office recently had issues with scan-to-email functionality. The manufacturer has an update ready to fix the printer issues. Which of the following would a technician most likely deploy to remediate the issue?
A. Firmware
B. Driver
C. OS update
D. HSM
Show Answer
Correct Answer: A
Explanation: The manufacturer's update for fixing functionality on the printer itself would be a firmware update. Firmware is the embedded software that controls the multifunction printer's hardware and built-in features such as scan-to-email. Drivers are installed on client computers, OS updates apply to operating systems, and an HSM (Hardware Security Module) is unrelated to printer feature remediation.
