Question 1

A company wants to deploy a custom web application that includes a custom database and a web server with specific modules. The development team needs full control over the operating system, including the ability to apply security patches and install third-party software. The company does not want to manage the physical servers, hypervisors, or network infrastructure. The cloud provider will be responsible for the underlying hardware and virtualization layer. Which cloud service model BEST meets these requirements?

Accepted Answer

Infrastructure as a Service (IaaS). Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, giving the customer full control over the operating system, including the ability to apply security patches and install third-party software. The cloud provider manages the physical servers, hypervisors, and network infrastructure, while the customer retains administrative access to the OS, which is essential for deploying a custom web application with a custom database and specific modules.

Answer

Software as a Service (SaaS)

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 2

A user reports that their workstation is displaying an 'IP address conflict' error message and cannot access the network. The technician runs ipconfig and sees IPv4 address 192.168.1.15 with subnet mask 255.255.255.0. Which of the following should the technician do FIRST to resolve the issue?

Accepted Answer

Run ipconfig /release and then ipconfig /renew. The 'IP address conflict' error indicates that another device on the same subnet is already using 192.168.1.15. The correct first step is to release the current DHCP lease with ipconfig /release and then request a new IP address with ipconfig /renew, which forces the DHCP client to obtain a fresh, non-conflicting address from the DHCP server.

Answer

Change the subnet mask to 255.255.0.0

Answer

Change the DNS server address to 8.8.8.8

Answer

Disable the Windows Firewall

Question 3

A user reports that their smartphone will not charge when connected to a USB port on their laptop, but it charges fine when plugged into a wall charger. The laptop's other USB ports work with a mouse and keyboard. Which of the following is the MOST likely cause?

Accepted Answer

Laptop USB port power output is too low. The most likely cause is that the laptop's USB port does not provide enough power to charge the smartphone. USB 2.0 ports typically supply up to 500 mA, while many modern smartphones require 1 A or more for charging. The wall charger can supply higher current, which is why charging works there. The fact that the mouse and keyboard work confirms the port is functional for low-power devices.

Answer

Faulty USB cable

Answer

Smartphone's battery is defective

Answer

Laptop USB drivers are outdated

Question 4

A user reports that their smartphone is not vibrating when receiving calls or notifications, even though the vibrate settings are enabled in the sound menu. The ringtone and speaker work normally. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The vibration motor is defective or disconnected. The vibration motor is a dedicated hardware component that physically oscillates to create the vibration sensation. If the phone's ringtone and speaker work normally but vibration fails despite the vibrate settings being enabled, the most likely cause is that the vibration motor itself is defective or has become disconnected from the motherboard. Software settings cannot override a failed hardware component.

Answer

Do Not Disturb mode is enabled

Answer

The phone is in silent mode

Answer

A recent software update caused a configuration error

Question 5

A user reports that their iPhone is not receiving email push notifications from the company's Exchange server. The email account is configured correctly, and the user can manually check email by opening the Mail app. Other users on the same Exchange server receive push notifications without issues. The technician checks the iPhone's Settings > Mail and sees 'Push' is enabled. Which of the following should the technician check NEXT?

Accepted Answer

The device's date and time settings are correct. Push notifications rely on a persistent connection between the device and the Exchange server, which is authenticated using the device's current time. If the date and time are incorrect, the TLS handshake or Kerberos authentication can fail, preventing the push channel from being established even though manual fetch works. Since other users on the same server receive push, the issue is device-specific, making incorrect date/time the most likely cause.

Answer

The iPhone's cellular data connection is active

Answer

The Exchange ActiveSync policy is blocking push for this device

Answer

The phone's Do Not Disturb schedule is active

Question 6

A user reports that their laptop loses network connectivity whenever they unplug the AC power adapter. When running on battery power alone, the laptop's Wi-Fi works intermittently or disconnects. The technician has verified that the Wi-Fi adapter driver is up to date and that the router is functioning correctly. Which of the following should the technician do NEXT to resolve this issue?

Accepted Answer

Disable the power-saving feature for the wireless adapter in Device Manager.. The issue is that the Wi-Fi adapter disconnects when the laptop switches to battery power, which is a classic symptom of the power-saving feature for the wireless adapter being enabled. This feature, controlled via the Power Management tab in Device Manager, can reduce power to the adapter to conserve battery life but often causes intermittent connectivity or disconnects. Disabling 'Allow the computer to turn off this device to save power' resolves the problem without replacing hardware or changing the overall power plan.

Answer

Replace the Wi-Fi adapter.

Answer

Update the BIOS firmware.

Answer

Change the power plan to High Performance.

Question 7

A user reports that their smartphone is running very slowly and the battery drains significantly faster than usual, even when the screen is off. The technician notices that the phone feels warm to the touch. Which of the following is the MOST likely cause of these symptoms?

Accepted Answer

Too many apps are running in the background.. When a smartphone feels warm, runs slowly, and drains battery quickly even with the screen off, the most likely cause is excessive background app activity. Background apps consume CPU cycles and keep the processor active, generating heat and draining the battery. This is a classic symptom of runaway background processes rather than a hardware failure or simple settings issue.

Answer

The screen brightness is set too high.

Answer

The operating system needs to be updated.

Answer

The battery is failing and needs to be replaced.

Question 8

A user reports that their network printer shows 'Offline' in the print queue on their Windows computer. The printer is powered on and has a link light on its network port. Other users on the same network can print to the printer without issue. Which of the following should the technician do FIRST?

Accepted Answer

Set the printer back online in the printer settings. The user's printer shows 'Offline' in the print queue, but it is powered on, has a link light, and other users can print to it. This indicates the printer and network are functioning correctly; the issue is that the printer's status on the user's computer has been set to 'Offline' or 'Use Printer Offline' in the printer properties. The first step is to set the printer back online by right-clicking the printer in 'Devices and Printers' and unchecking 'Use Printer Offline' or selecting 'See what's printing' and clicking 'Printer' > 'Use Printer Online'.

Answer

Restart the print spooler service on the user's computer

Answer

Reinstall the printer driver on the user's computer

Answer

Power cycle the printer

Question 9

A user reports that their laptop is connected to the office Wi-Fi and can browse the internet, but cannot access any shared folders on the network. Other laptops on the same Wi-Fi can access the shares without issue. The laptop received a valid IP address from DHCP. Which of the following should the technician check FIRST?

Accepted Answer

The network profile is set to Public. The network profile being set to Public applies Windows Firewall rules that block file and printer sharing (SMB traffic on ports 445, 139) by default. Since the user can browse the internet but cannot access shared folders, and other laptops work fine, the most likely cause is that the laptop's network profile is Public, which disables network discovery and file sharing. Changing it to Private or Domain profile resolves the issue without affecting internet connectivity.

Answer

The DNS server configuration

Answer

A faulty wireless network adapter

Answer

Duplicate IP address on the network

Question 10

A user reports that their laptop cannot access the internet but can still access shared files on the local network. The technician runs ipconfig and sees an IP address of 169.254.15.32. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The DHCP server is unavailable. The IP address 169.254.15.32 is an Automatic Private IP Addressing (APIPA) address, which Windows assigns when a DHCP server is unavailable and the client fails to obtain a lease. Since the laptop can still access local shared files, the local network is functional, but without a valid DHCP-assigned IP, it cannot reach external networks or the internet. This directly points to the DHCP server being unavailable.

Answer

The DNS server is not responding

Answer

The default gateway is misconfigured

Answer

The subnet mask is incorrect

Question 11

A user reports that their iPhone 13 does not charge when plugged into the wall outlet using the original charging cable and adapter. The technician tries a different known-good Lightning cable and wall adapter, but the phone still does not charge. The technician inspects the Lightning port on the phone and sees that the port opening appears clean with no visible debris. Which of the following is the BEST next step to troubleshoot this issue?

Accepted Answer

Use a non-conductive tool (e.g., a plastic toothpick) to carefully probe the Lightning port and remove any hidden debris.. Option C is correct because the technician's visual inspection may miss compacted debris deep inside the Lightning port. Using a non-conductive tool to gently probe can dislodge hidden lint or dirt that prevents proper contact between the Lightning connector and the port's pins, restoring charging capability without risking a short circuit.

Answer

Reset the network settings to rule out a software conflict affecting charging.

Answer

Connect the phone to a computer and perform a full restore via iTunes.

Answer

Replace the iPhone's battery immediately, as a dead battery is the most likely cause.

Question 12

A user reports that their wired desktop computer intermittently loses network connectivity. The technician checks the Ethernet cable and observes that it is not securely clicked into the NIC port. The cable appears undamaged and the connector is intact. Which of the following is the MOST likely cause of the intermittent connectivity?

Accepted Answer

Loose cable connection. The technician observed that the Ethernet cable is not securely clicked into the NIC port. A loose physical connection at the RJ45 connector can cause intermittent link drops because the electrical contacts may momentarily lose continuity, triggering a link flap. This is the most direct cause given the cable and connector appear undamaged.

Answer

Faulty switch port

Answer

Incorrect IP address

Answer

DHCP server issue

Question 13

A user reports that their workstation intermittently loses network connectivity. The technician checks the IP configuration during an outage and finds the IP address is 169.254.12.34. The network uses DHCP, and other workstations on the same subnet are functioning normally. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The network cable is either faulty or not fully seated.. The 169.254.x.x address is an Automatic Private IP Addressing (APIPA) address, assigned by the OS when DHCP fails. Since other workstations on the same subnet are working, the DHCP server and switch port are functional, isolating the issue to the local link. A faulty or loose cable can cause intermittent connectivity, leading to DHCP discovery failures and APIPA assignment.

Answer

The DHCP server has run out of IP addresses.

Answer

The network switch port is administratively shut down.

Answer

The workstation's network adapter driver is corrupted.

Question 14

A user reports that their laptop's battery indicator shows 'plugged in, not charging.' The technician tests the AC adapter with a multimeter and verifies it outputs the correct voltage. The laptop is a standard model with a removable battery. Which of the following components is MOST likely faulty?

Accepted Answer

Battery. The battery indicator showing 'plugged in, not charging' with a verified good AC adapter strongly points to a faulty battery. Since the adapter outputs correct voltage, the laptop detects the external power source (hence 'plugged in') but the battery itself cannot accept a charge, often due to degraded cells or failed internal protection circuitry. A removable battery is a common failure point, especially in older or heavily used laptops.

Answer

DC power jack

Answer

Motherboard charging circuit

Answer

Power management IC

Question 15

A user reports that their smartphone will not charge when connected to a known-good charger and cable. The technician examines the charging port and sees debris inside. Which of the following tools should the technician use to safely remove the debris?

Accepted Answer

A wooden toothpick. A wooden toothpick is non-conductive and non-abrasive, making it safe to dislodge debris from a smartphone charging port without risking short circuits or damaging the delicate pins inside the USB-C or Lightning connector. Metal tools can cause electrical shorts or scratch the port's contacts, while compressed air may push debris deeper, and alcohol with a cotton swab can leave fibers or moisture that interfere with charging.

Answer

A metal paperclip

Answer

A can of compressed air

Answer

Isopropyl alcohol and a cotton swab
