Question 2

A user's smartphone will not charge when connected to the charger. The technician has verified that the charger and cable work with another phone, and the charging port appears clean and free of debris. Which of the following should the technician try FIRST?

Accepted Answer

Use a wireless charger if supported.. Since the charger and cable are verified working and the port is clean, the issue is likely with the phone's charging circuitry. Using a wireless charger (if supported) bypasses the physical charging port entirely, isolating whether the problem is with the port or the phone's internal charging system. This is the quickest and least invasive test before attempting more disruptive steps.

Answer

Replace the battery.

Answer

Perform a hard reset.

Answer

Boot into safe mode.

Question 3

A technician builds a new PC and installs two 8GB DDR4 RAM modules from the same kit into the appropriate slots on the motherboard. The system boots and the BIOS reports only 8GB of total memory. The technician has reseated the modules and verified they are fully inserted. The motherboard manual indicates that the slots used are correct for dual-channel configuration. Which of the following is the MOST likely cause?

Accepted Answer

One of the RAM modules is defective.. The system detects only 8GB of total memory despite having two 8GB modules installed. Since both modules are from the same kit and the slots are confirmed correct, the most likely cause is that one of the modules is defective. A faulty module will not be recognized by the BIOS, resulting in half the expected capacity.

Answer

The RAM modules are not compatible with the CPU.

Answer

The motherboard's memory slot is damaged.

Answer

The RAM is running at the wrong voltage.

Question 4

A user's smartphone has become intermittent: the screen flickers and sometimes goes completely black for a few seconds before returning to normal. The phone has not been dropped recently and there is no visible damage. The technician has already performed a soft reset and the issue persists. Which of the following is the most likely cause?

Accepted Answer

Loose internal display cable. The intermittent screen flickering and blackouts, without physical damage or drop history, strongly point to a loose internal display cable. A soft reset did not resolve the issue, ruling out temporary software glitches. The display cable connects the screen to the motherboard; if it becomes slightly unseated due to thermal expansion or vibration, it can cause intermittent signal loss, leading to the described symptoms.

Answer

Failing battery

Answer

Corrupted operating system

Answer

Faulty digitizer

Question 5

A technician is installing several wireless access points in a large office to provide Wi-Fi coverage. The access points are PoE-capable, but the existing network switches do not support Power over Ethernet. The access points are located too far from available power outlets. Which of the following devices should the technician use to provide both data connectivity and power to the access points?

Accepted Answer

PoE injector. A PoE injector is the correct choice because it inserts power into the Ethernet cable between the non-PoE switch and the PoE-capable access point, providing both data and power over a single cable. This solves the problem of the access points being too far from power outlets without requiring replacement of the existing switches.

Answer

PoE switch

Answer

Network hub

Answer

Power supply unit

Question 6

A user reports that their iPhone charges very slowly when connected to a USB port on their laptop, but charges normally using the included wall adapter. The cable is known to be functional. Which of the following is the MOST likely cause?

Accepted Answer

The laptop's USB port is a USB 2.0 port outputting lower current. USB ports on laptops, especially USB 2.0 ports, are typically limited to 500 mA (0.5 A) of current per the USB 2.0 specification. iPhones require higher current (typically 1 A or more) for fast charging, and the wall adapter provides that higher current. The slow charging is due to the laptop's USB port being unable to supply enough current, not a cable or software issue.

Answer

The iPhone's Lightning port is damaged

Answer

The laptop's USB driver is outdated

Answer

The iPhone's battery needs calibration

Answer

C. Software as a Service (SaaS)

Answer

D. Function as a Service (FaaS)

Question 8

A technician is troubleshooting a desktop computer running Windows 10 that has no network connectivity. The computer is connected via an Ethernet cable to a managed switch. The technician observes that the link light on the network interface card (NIC) is off, but the link light on the switch port is solid green. The technician tests the Ethernet cable with a cable tester and it passes. Connecting a different laptop to the same cable and switch port results in a successful connection. The technician boots the problematic computer from a Linux live USB drive and finds that the NIC link light comes on and the computer can access the network normally. After rebooting back into Windows, the NIC link light is off again and there is no connectivity. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The Windows NIC driver is corrupted or incompatible.. The NIC works under Linux but fails under Windows, which isolates the issue to the Windows software environment. A corrupted or incompatible NIC driver can prevent the OS from initializing the hardware, causing the link light to remain off and no connectivity. Since the hardware passes a cable test and works with another OS, the driver is the most likely cause.

Answer

The NIC is physically faulty.

Answer

The switch port is configured with port security.

Answer

The Ethernet cable is not properly seated.

Question 9

A company hosts a database virtual machine in a public IaaS cloud. The VM is experiencing slow performance due to high disk I/O latency. The administrator wants to improve performance without changing the VM size (vCPU or RAM). Which of the following actions would MOST likely resolve the issue?

Accepted Answer

Migrate the VM to a storage tier with higher IOPS. Migrating the VM to a storage tier with higher IOPS directly addresses the high disk I/O latency by providing faster data access at the storage layer. Since the VM size (vCPU/RAM) remains unchanged, improving the underlying storage performance is the most effective way to reduce latency without altering compute resources.

Answer

Increase the amount of RAM allocated to the VM

Answer

Add more vCPUs to the VM

Answer

Enable nested virtualization on the host

Question 10

A technician is setting up a small office network with a single internet connection from a cable modem. The office has two departments: Accounting and Sales. The technician needs to ensure that devices in Accounting cannot communicate with devices in Sales, but both departments must be able to access the internet. Which feature should the technician configure on the managed switch to meet this requirement?

Accepted Answer

Configure VLANs on the managed switch. VLANs (Virtual Local Area Networks) logically segment a switch into multiple isolated broadcast domains. By placing Accounting devices in one VLAN and Sales devices in another, the switch prevents Layer 2 communication between them, while both VLANs can still access the internet through a router configured with inter-VLAN routing or a separate uplink.

Answer

Enable DHCP on the router

Answer

Set up port forwarding on the router

Answer

Configure NAT on the router

Question 11

A user reports that their iPhone charges very slowly and only when the Lightning cable is held at a specific angle. The user has tried multiple known-good chargers and cables, but the issue persists. The technician inspects the Lightning port on the phone and sees what appears to be lint compacted at the bottom. Which of the following is the BEST next step for the technician to resolve this issue?

Accepted Answer

Gently clean the port with a wooden toothpick. The lint compacted at the bottom of the Lightning port is preventing the connector from seating fully, causing intermittent charging. Gently cleaning the port with a wooden toothpick is the safest and most effective method to dislodge the debris without damaging the delicate pins inside the port. This resolves the issue without replacing hardware or performing software resets.

Answer

Use compressed air to blow out the debris from the port

Answer

Replace the Lightning port assembly

Answer

Perform a factory reset on the iPhone

Question 12

A user reports that their smartphone cannot detect any Bluetooth devices. The technician has verified that Bluetooth is enabled in the settings, and the other Bluetooth devices are powered on and in discoverable mode. Which of the following should the technician check next?

Accepted Answer

Whether the smartphone is in Airplane mode. Airplane mode disables all wireless radios, including Bluetooth, Wi-Fi, and cellular. Even if Bluetooth is toggled on in settings, enabling Airplane mode overrides this and prevents the Bluetooth radio from transmitting or scanning, so the smartphone cannot detect any Bluetooth devices. The technician should verify that Airplane mode is off before proceeding with other troubleshooting steps.

Answer

Whether the SIM card is inserted properly

Answer

The condition of the charging port

Answer

The brightness of the screen

Question 13

A financial services company needs to migrate its customer transaction processing system to the cloud. Regulatory requirements mandate that all customer data must reside on servers physically located within the country’s borders and that the hardware must be dedicated solely to the company (no multi-tenancy at the hardware level). The company wants to retain the ability to scale resources on demand and manage the operating system and applications. Which cloud deployment model BEST meets these requirements?

Accepted Answer

Private cloud. A private cloud provides dedicated physical resources that are not shared with other organizations, offering the required isolation and control. It can be hosted on-premises or by a third-party provider with exclusive hardware. A public cloud would involve shared hardware, violating the requirement. A hybrid cloud combines public and private but does not guarantee full isolation. A community cloud is shared among several organizations with common concerns, but still not dedicated to one company.

Answer

Public cloud

Answer

Hybrid cloud

Answer

Community cloud

Question 14

A user reports that they can browse the internet and access all network resources by IP address, but they cannot print to the network printer by its hostname. Other users can print using the hostname without issue. The technician pings the printer's IP address from the affected computer and gets a successful reply. Which of the following should the technician check next?

Accepted Answer

The DNS server settings on the user's computer. The user can browse the internet and access resources by IP address but not by hostname, which points to a name resolution failure. Since other users can print to the network printer by hostname, the printer and DNS server are functioning correctly. The issue is isolated to the affected computer's DNS configuration, making checking the DNS server settings on the user's computer the next logical step.

Answer

The printer's firewall settings

Answer

The user's network cable

Answer

The router's NAT configuration

Question 15

A company uses a cloud service that allows them to automatically increase the number of web server instances during peak traffic periods and decrease them during off-peak hours. They only pay for the instances they use. This scenario best exemplifies which characteristic of cloud computing?

Accepted Answer

Elasticity. Elasticity in cloud computing refers to the ability to automatically scale resources up or down based on demand. In this scenario, the company automatically increases web server instances during peak traffic and decreases them during off-peak hours, paying only for what they use, which is the defining behavior of elasticity.
