Accepted Answer

Remove the phone case and clean around the button with compressed air. A stuck physical button on a smartphone is often caused by debris, such as dust or lint, lodged around the button, or by a case that is pressing against it. The best first step is to remove any case and gently clean around the button with compressed air. Factory reset and firmware reflash are software solutions that cannot fix a physical obstruction. Replacing the display assembly is unnecessary and costly for a button issue.

Answer

Perform a factory reset

Answer

Replace the display assembly

Answer

Reflash the firmware

Question 2

A technician is installing a new M.2 NVMe SSD into a desktop computer that previously used only SATA drives. After physically installing the drive, the BIOS does not detect the new M.2 SSD. The technician confirms the M.2 slot on the motherboard supports NVMe and the drive is properly seated. Which of the following should the technician check NEXT?

Accepted Answer

Check for a BIOS update that adds NVMe support. The motherboard supports NVMe, but the BIOS may not have the necessary NVMe driver or firmware support to recognize the drive. A BIOS update often adds NVMe support for older chipsets or UEFI implementations, which is the most likely next step before troubleshooting other components.

Answer

Ensure the SATA data cables are not obstructing the M.2 slot

Answer

Inspect the device manager in Windows for uninitialized drives

Answer

Swap the M.2 drive to the other M.2 slot if available

Question 3

A user reports that their Android smartphone's volume rocker button is physically stuck in the pressed position. The phone is still functioning, but the volume constantly decreases to zero and cannot be adjusted. Which of the following is the BEST first step?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Defective battery. A bulging battery indicates internal chemical degradation, often due to lithium-ion cell failure from overcharging, age, or manufacturing defects. This swelling can cause internal short circuits, leading to excessive heat generation during charging and rapid self-discharge even when idle. Since the charger and cable are known functional, the battery itself is the most likely root cause.

Answer

Faulty charging port

Answer

Failed power management IC

Answer

Damaged screen

Question 4

A user in a small office reports that they can access websites on the internet but cannot connect to the company's internal file server using its hostname (\fileserver). Other users in the same office can access the file server by hostname without any issues. The technician runs ipconfig /all on the affected workstation and sees the following: IPv4 Address: 192.168.1.45, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.1, DNS Server: 8.8.8.8. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The workstation is using an external DNS server instead of the internal DNS server.. The workstation can access the internet (via 8.8.8.8) but cannot resolve the internal hostname 'fileserver' because it is using an external DNS server (Google's 8.8.8.8) instead of the internal DNS server that holds the private DNS records for the company's local resources. Internal DNS servers typically host A or CNAME records for internal hostnames, which public DNS servers like 8.8.8.8 do not contain. This mismatch prevents hostname resolution for the file server while leaving internet access functional.

Answer

The workstation's subnet mask is incorrect.

Answer

The default gateway is misconfigured.

Answer

The DHCP scope is exhausted.

Question 5

Accepted Answer

The app's background activity and location permissions. After an app update, the most likely cause of excessive battery drain is that the app is using background services, such as location, syncing, or other tasks. Closing apps from the app switcher may not fully stop background processes. The user should check the app's permissions and battery usage settings to revoke unnecessary background activity or force stop the app.

Answer

The screen brightness settings

Answer

The battery calibration

Answer

The Wi-Fi and Bluetooth settings

Question 6

A technician is troubleshooting a desktop computer that experiences brief network disconnections lasting 5-10 seconds several times an hour. During the disconnections, the network activity and link lights on both the NIC and the switch remain illuminated. The technician has replaced the Ethernet cable, updated the NIC driver, and disabled power saving settings for the NIC. The issue persists. Which of the following should the technician do NEXT?

Accepted Answer

Perform a loopback test on the NIC. The correct next step is to perform a loopback test on the NIC. Since the link lights remain active during disconnections, the physical layer (cable, switch port) appears intact, and the issue persists after replacing the cable, updating the driver, and disabling power saving. A loopback test isolates whether the NIC itself can successfully send and receive data internally, ruling out internal NIC failure or a faulty transceiver without relying on external network traffic.

Answer

Check for an IP address conflict on the network

Answer

Replace the network switch

Answer

Review the system event logs for network-related errors

Question 7

A technician is setting up a small office network with 15 computers, a router, and an unmanaged switch. The computers are configured with static IP addresses. After connecting all computers to the switch, the technician notices that some computers can communicate with each other but cannot access the internet. The router's LAN IP is 192.168.1.1 with subnet mask 255.255.255.0. The computers have IP addresses in the range 192.168.1.2-192.168.1.16 with default gateway 192.168.1.1. The technician pings the router from a computer that cannot access the internet, and the ping times out. Which of the following is the MOST likely cause?

Accepted Answer

The Ethernet cable connecting the switch to the router is faulty.. The ping from a computer to the router (192.168.1.1) times out, indicating that Layer 3 connectivity to the router is absent. Since the switch is unmanaged and operates at Layer 2, it does not perform VLAN routing or filtering; the most likely cause is a physical or data-link layer issue on the link between the switch and the router, such as a faulty Ethernet cable. A faulty cable would prevent frames from reaching the router, causing the ping timeout and the inability to access the internet.

Answer

The switch is not forwarding traffic to the router due to a VLAN mismatch.

Answer

The computers are configured with the wrong subnet mask.

Answer

The router's firewall is blocking ICMP traffic.

Question 8

A technician is adding a new RAID controller to a server. After installing the card into a PCIe slot and connecting the internal cables, the server powers on but does not POST. The fans spin and power LED is on, but there is no display output or beep codes. The technician removes the RAID controller and the server boots normally. The technician reseats the controller in a different PCIe slot, but the same symptom occurs. The controller is listed as compatible with the server model. Which of the following is the MOST likely cause?

Accepted Answer

The RAID controller requires more power than the PCIe slot can provide. The RAID controller is a high-power PCIe device that may exceed the 75W power limit of a standard PCIe slot. When the controller draws more power than the slot can supply, the motherboard may fail to initialize the device during POST, causing a no-POST condition with fans spinning and no beep codes. Removing the controller allows the system to boot normally, confirming the power draw issue.

Answer

The PCIe slot is defective

Answer

The server's BIOS needs to be updated

Answer

The RAID controller's firmware is corrupted

Question 9

A small business wants to migrate its internal applications to the cloud to reduce hardware maintenance costs. They wish to retain control over the application code and configuration but do not want to manage the underlying operating system or runtime environment. Which cloud service model BEST meets their needs?

Accepted Answer

Platform as a Service (PaaS). Platform as a Service (PaaS) provides a managed platform where the customer controls the application code and configuration, while the cloud provider handles the underlying OS and runtime environment. This aligns with the requirement to reduce hardware maintenance costs without managing the OS or runtime.

Answer

Software as a Service (SaaS)

Answer

Infrastructure as a Service (IaaS)

Answer

Desktop as a Service (DaaS)

Question 10

A technician is troubleshooting a laser printer that produces pages with vertical black streaks running from the top to the bottom of the page. The technician has already replaced the toner cartridge and the drum unit, but the problem persists. Which printer component should the technician inspect or replace NEXT?

Accepted Answer

Fuser assembly. Vertical black streaks that persist after replacing the toner cartridge and drum unit are most likely caused by a damaged fuser assembly. The fuser uses heat and pressure to bond toner to the paper; if its roller is scratched or contaminated, it can leave continuous black streaks. Since the toner and drum have been replaced and the problem continues, the fuser is the next component to inspect.

Answer

Transfer roller

Answer

Laser scanner assembly

Answer

Paper pickup roller

Question 11

A network technician is setting up a wireless access point (AP) for a small business. The company's router provides DHCP for the 192.168.1.0/24 network. The AP needs to broadcast two SSIDs: one for employees and one for guest users. The guest network must be completely isolated from the employee network and internal resources, while both SSIDs must have internet access. The AP is connected to a managed switch. Which configuration will BEST meet these requirements?

Accepted Answer

Configure VLANs on the managed switch and set the AP to tag the employee SSID on VLAN 10 and the guest SSID on VLAN 20; configure trunk port on switch to the AP. It uses VLANs to logically separate the employee and guest traffic at Layer 2. By configuring the managed switch port as a trunk with VLAN 10 (employee) and VLAN 20 (guest), and having the AP tag each SSID to its respective VLAN, the guest network is isolated from the employee network and internal resources. The router can then route both VLANs to the internet via separate subinterfaces or a Layer 3 switch, ensuring both SSIDs have internet access while maintaining isolation.

Answer

Place both SSIDs on the same subnet and enable client isolation on the AP

Answer

Configure a DHCP reservation on the router for the AP and set the guest SSID to use a static IP in a different subnet

Answer

Disable the guest network's ability to access the default gateway by changing the AP's management settings

Question 12

A company uses a hypervisor to run multiple virtual machines on a single physical server. The host server has 64 GB of RAM. The administrator allocates 8 GB of RAM to each of 10 VMs, for a total allocation of 80 GB. The hypervisor utilizes memory overcommitment, which allows the total allocated memory to exceed the physical memory by sharing idle memory pages among VMs. Which of the following cloud computing characteristics does this configuration BEST demonstrate?

Accepted Answer

Resource pooling. Resource pooling is the cloud characteristic demonstrated because the hypervisor aggregates the physical memory (64 GB) into a shared pool and dynamically allocates it to multiple VMs as needed, even though the total allocated memory (80 GB) exceeds the physical capacity. Memory overcommitment relies on the hypervisor's ability to reclaim idle pages from one VM and assign them to another, which is a direct implementation of resource pooling where physical resources are abstracted and shared among tenants.

Answer

On-demand self-service

Answer

Rapid elasticity

Answer

Measured service

Question 13

A user reports that their iPhone displays 'No SIM' even though the SIM card is properly inserted. The technician has already removed and reinserted the SIM, and performed a restart. Which of the following should the technician do NEXT to isolate the issue?

Accepted Answer

Try the SIM card in another compatible phone.. The technician has already performed basic troubleshooting (reseating the SIM and restarting the device). The next logical step is to test the SIM card in another compatible phone to determine whether the issue lies with the SIM card itself or with the iPhone's SIM reader/baseband. This isolates the fault domain before proceeding with more invasive or irreversible steps.

Answer

Reset network settings.

Answer

Check for a carrier settings update.

Answer

Replace the SIM card with a new one.

Question 14

An administrator is configuring a file server with three identical hard drives. The server requires fault tolerance; it must be able to survive the failure of any one drive without data loss. Additionally, the configuration should maximize usable storage space. Which RAID level should the administrator implement?

Accepted Answer

RAID 5. RAID 5 is the correct choice because it provides fault tolerance for a single drive failure while maximizing usable storage. With three identical drives, RAID 5 uses distributed parity to allow the array to survive any one drive failure without data loss, and the usable capacity is (n-1) drives, or 2 drives' worth of space. RAID 0 offers no redundancy, RAID 1 would waste 2/3 of the capacity with only 1 drive usable, and RAID 10 requires a minimum of 4 drives.

Answer

RAID 0

Answer

RAID 1

Answer

RAID 10

Question 15

A user's Android phone screen is cracked but still works. The user wants to continue using the phone temporarily without risk of glass cuts or further damage. What is the BEST immediate solution?

Accepted Answer

Apply a tempered glass screen protector. Applying a tempered glass screen protector over the cracked screen will hold the broken glass together, preventing glass fragments from falling out and reducing the risk of cuts. Replacing the digitizer is a permanent repair, not immediate. Using gloves is impractical for daily use and does not protect the phone from further damage. Removing the broken glass can expose internal components and is dangerous. A screen protector is the safest temporary measure.

Answer

Replace the digitizer

Answer

Use the phone with gloves

Answer

Remove the broken glass
