Question 2

A user has link lights on a network port but receives very slow file transfers. The switch reports many CRC errors on the port. What is the most likely cause?

Accepted Answer

Faulty or damaged Ethernet cable. CRC errors indicate that frames are being corrupted during transmission, which is a classic symptom of a faulty or damaged Ethernet cable. A damaged cable can cause signal degradation, leading to bit errors that the switch detects as CRC mismatches, resulting in retransmissions and slow file transfers.

Question 9

A technician is assembling a new desktop computer. After installing the CPU, heat sink, and RAM, the technician powers on the system. The fans spin for a moment, then the system shuts down. The CPU fan does not spin at all. Which of the following is the MOST likely cause?

Accepted Answer

The CPU fan connector is not plugged into the CPU_FAN header.. The CPU fan connector must be plugged into the motherboard's CPU_FAN header for the fan to receive power and for the system to detect fan operation. Many motherboards have a safety feature that shuts down the system within seconds if no fan signal is detected on the CPU_FAN header, preventing CPU overheating. Since the CPU fan does not spin at all, the most likely cause is that the connector is not attached to the correct header.

Answer

The CPU is not compatible with the motherboard.

Answer

The RAM is not seated properly.

Answer

The power supply is insufficient.

Question 10

A technician installs a new CPU into an existing desktop motherboard that is listed as compatible. When the system is powered on, the fans spin and LEDs light up, but the screen remains black, and there are no POST beeps. The technician has reseated the RAM and GPU, and verified the power supply voltages are within spec. Which of the following should the technician check NEXT?

Accepted Answer

Check the CPU socket for bent pins. The symptoms—fans spin, LEDs light, but no POST and no beeps—indicate the motherboard is receiving power but the CPU is not initializing. Since the CPU is listed as compatible but was just installed, the most likely cause is physical damage to the CPU socket, such as bent pins, which prevents proper contact between the CPU and the motherboard. Reseating RAM and GPU and verifying PSU voltages already ruled out those common issues, making a socket inspection the logical next step.

Answer

Update the motherboard BIOS to the latest version

Answer

Replace the power supply with a higher-wattage unit

Answer

Test each RAM module one at a time in different slots

Question 11

A technician is building a new desktop PC. After installing the CPU, RAM, motherboard, and power supply, the technician connects the monitor to the motherboard's video output. When the PC is powered on, the fans spin, but no display appears and no beep codes are heard. The technician has verified that the monitor works with another computer. Which of the following should the technician do NEXT?

Accepted Answer

Reseat the RAM modules.. The system is powering on (fans spin) but no display and no beep codes indicate a hardware fault during POST, often caused by improperly seated RAM. Reseating the RAM is a quick, non-invasive first step to ensure good contact. If the RAM were the issue, the motherboard would typically not produce beep codes or display output. Installing a dedicated GPU would not resolve a RAM seating problem.

Answer

Install a dedicated graphics card.

Answer

Replace the power supply.

Answer

Replace the motherboard.

Question 12

A company wants to migrate its on-premises email system to the cloud. They require a solution where the cloud provider manages the email servers, software updates, security patches, and storage infrastructure, while the company retains control over user accounts, mailbox policies, and email content. Which cloud service model BEST fits these requirements?

Accepted Answer

Software as a Service (SaaS). Software as a Service (SaaS) delivers a complete, managed application to end users. In this scenario, the cloud provider handles all underlying infrastructure, including email servers, software updates, security patches, and storage, while the customer retains administrative control over user accounts, mailbox policies, and email content. This matches the definition of SaaS, where the provider manages the entire application stack and the customer only manages application-level settings.

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 13

A technician connects a new workstation to a managed switch port. The workstation receives an IP address from the DHCP server and can ping its own IP address, but it cannot ping any other devices on the local network, including the default gateway. The technician verifies that the Ethernet cable is functional and that the link lights are solid on both the NIC and the switch port. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The switch port is configured with an incorrect VLAN assignment.. The workstation receives an IP address and can ping itself, confirming Layer 3 configuration is functional. However, it cannot ping other devices on the local network, including the default gateway. Since the cable and link lights are good, the issue is at Layer 2. An incorrect VLAN assignment on the switch port isolates the workstation into a different broadcast domain, preventing it from communicating with devices in the correct VLAN, including the gateway.

Answer

The workstation's network adapter is set to half-duplex.

Answer

The DHCP server has excluded the workstation's MAC address.

Answer

The default gateway is not configured on the switch.

Question 14

A company runs multiple virtual machines (VMs) on a single hypervisor host. The administrator wants to ensure that if one VM is compromised by malware, it cannot read the memory contents of other VMs running on the same host. Which hypervisor feature primarily provides this protection?

Accepted Answer

Virtual machine isolation. Virtual machine isolation is the hypervisor feature that prevents one VM from accessing the memory or processes of another VM on the same host. Each VM runs in its own isolated execution environment, enforced by the hypervisor's memory management unit (MMU) and hardware-assisted virtualization technologies like Intel VT-x or AMD-V. This ensures that even if a VM is compromised by malware, it cannot read the memory contents of co-resident VMs.

Answer

Resource pooling

Answer

Memory ballooning

Answer

Virtual machine snapshots

Question 15

A technician is troubleshooting a desktop computer that powers on (fans spin, LEDs light) but the monitor displays 'No Signal.' The technician has already verified the monitor is functional by testing it with another computer, and the video cable is securely connected to both the computer and monitor. The computer has both an integrated GPU on the motherboard and a discrete graphics card installed. Which of the following should the technician do NEXT?

Accepted Answer

Remove the discrete graphics card and connect the monitor to the motherboard's video port. The correct next step is to remove the discrete graphics card and connect the monitor to the motherboard's video port. This isolates whether the discrete GPU is faulty or improperly seated, because the system may be defaulting to the discrete card even if it is malfunctioning, preventing the integrated GPU from outputting video. Since the monitor and cable are verified functional, the issue is likely with the video output path, and testing the integrated GPU bypasses the discrete card entirely.

Answer

Replace the RAM modules with known-good sticks

Answer

Check the monitor's input source setting

Answer

Reseat the discrete graphics card in its PCIe slot
