Question 1

A company runs its virtualized infrastructure on a cluster of hypervisor hosts. The administrator configures the cluster to automatically move virtual machines to other hosts in the event of a planned host maintenance, minimizing downtime. The administrator also wants to ensure that virtual machines are redistributed to balance CPU and memory utilization across the cluster periodically. Which two technologies or features are being utilized? (Select TWO.)

Accepted Answer

vMotion. vMotion is the VMware technology that enables live migration of running virtual machines between hypervisor hosts with zero downtime, making it the correct choice for moving VMs during planned host maintenance. The scenario explicitly describes moving VMs automatically to other hosts for maintenance, which is the primary function of vMotion.

Answer

Fault Tolerance (FT)

Answer

High Availability (HA)

Question 2

A technician is troubleshooting a laser printer that is printing blank pages. The toner cartridge is new and installed correctly. The printer performs its startup cycle normally. Which of the following components should the technician check NEXT?

Accepted Answer

Transfer roller. The transfer roller applies a positive charge to the paper to attract the negatively charged toner from the imaging drum. If the transfer roller fails, toner is not transferred to the paper, resulting in blank pages even though the printer startup cycle completes normally and a new toner cartridge is installed correctly.

Answer

Fuser

Answer

Pickup rollers

Answer

Imaging drum

Question 3

A technician is troubleshooting a user's laptop that connects to the corporate Wi-Fi network successfully and obtains a valid IP address in the 192.168.x.x range. However, the user cannot access the internet or any internal servers. Other devices on the same Wi-Fi network are working fine. Which of the following should the technician check FIRST?

Accepted Answer

The laptop's network profile type. The laptop obtains a valid IP address (192.168.x.x) and connects to Wi-Fi, but cannot reach the internet or internal servers while other devices work. This points to a local configuration issue on the laptop, not the network infrastructure. The network profile type (Public, Private, or Domain) controls Windows Firewall rules; a Public profile often blocks file/print sharing and can block access to internal servers or even the default gateway, while still allowing DHCP and DNS. Checking this first is quick and non-invasive, and it directly addresses a common misconfiguration that matches the symptoms.

Answer

The DHCP server's IP address pool

Answer

The default gateway's MAC address

Answer

The DNS server settings

Question 4

A technician is troubleshooting a desktop PC that emits one long beep followed by three short beeps immediately after pressing the power button. The system does not display any video. The motherboard uses an AMI BIOS. Which of the following is the MOST likely cause of the beep code?

Accepted Answer

Memory (RAM) failure. AMI BIOS uses a beep code of one long followed by three short beeps to indicate a memory (RAM) failure. This code typically means the system cannot read or initialize the RAM modules, which prevents the POST process from completing and results in no video output.

Answer

Video card failure

Answer

CPU failure

Answer

Power supply failure

Question 5

A technician is troubleshooting a desktop PC that powers on (fans spin, LEDs light up) but does not display anything and produces no POST beeps. The motherboard has four diagnostic LEDs labeled CPU, DRAM, VGA, and BOOT. When the system is powered on, the DRAM LED remains solid red. The technician has verified that the RAM module (single 16GB DDR4 stick) is fully seated in slot A2, as recommended by the motherboard manual. The technician has also reseated the GPU and checked all power connections. Which of the following should the technician do NEXT?

Accepted Answer

Try a different RAM slot. The DRAM LED remaining solid red indicates a memory initialization failure. Since the single RAM stick is already fully seated in the recommended slot A2, the next logical step is to try a different RAM slot (e.g., A1 or B2) to rule out a faulty slot or a subtle contact issue. This is a standard first step in memory troubleshooting before replacing components.

Answer

Replace the motherboard

Answer

Reinstall the CPU, checking for bent pins

Answer

Update the motherboard BIOS

Question 6

A company wants to move its email system to the cloud. The cloud vendor provides the email service, including server hardware, operating system, and software. The company only needs to manage user accounts and mailboxes. Which cloud service model is the vendor providing?

Accepted Answer

Software as a Service (SaaS). The vendor provides the entire email service, including server hardware, operating system, and software, while the company only manages user accounts and mailboxes. This matches the Software as a Service (SaaS) model, where the provider delivers a complete application over the internet, and the customer has no control over the underlying infrastructure or platform.

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 7

A network technician connects two switches together using a straight-through Cat6 Ethernet cable. Both switches are managed and are known to be working. After connecting, the link LED on Switch A is off, and the link LED on Switch B is also off. The technician has verified that both switch ports are enabled and not administratively shut down. Which of the following is the MOST likely cause of the problem?

Accepted Answer

At least one switch does not support auto-MDIX.. When two switches are connected directly, auto-MDIX (Automatic Medium-Dependent Interface Crossover) allows either a straight-through or crossover cable to be used by automatically negotiating the transmit/receive pairs. If at least one switch does not support auto-MDIX, a straight-through cable will not work because the transmit pins on one switch will connect to transmit pins on the other, causing a link failure. Since both link LEDs are off and the ports are enabled, the most likely cause is that one or both switches lack auto-MDIX support, requiring a crossover cable instead.

Answer

The cable is a crossover cable.

Answer

The cable length exceeds 100 meters.

Answer

One of the switches has the wrong VLAN assignment.

Question 8

A company uses a cloud service where administrators can provision virtual machines with pre-configured operating systems and applications from a catalog. They can scale the number of VMs up or down as needed, but they are responsible for managing the guest OS and applications. Which cloud service model does this describe?

Accepted Answer

Infrastructure as a Service (IaaS). This scenario describes Infrastructure as a Service (IaaS) because the cloud provider supplies virtualized hardware resources (VMs, storage, networking), while the customer retains full control over the guest operating system and applications. The administrator provisions pre-configured VMs from a catalog and scales them up or down, but is responsible for OS patching, application management, and security within the VM. This aligns with the IaaS shared responsibility model where the provider manages the hypervisor and physical infrastructure, and the customer manages everything above the OS layer.

Answer

Platform as a Service (PaaS)

Answer

Software as a Service (SaaS)

Answer

Desktop as a Service (DaaS)

Question 9

A company runs multiple virtual machines on a single hypervisor host running a Type 2 hypervisor on a Windows Server. The IT team needs to give a graphics-intensive VM direct access to the physical GPU for CAD rendering. Which of the following technologies should be implemented?

Accepted Answer

GPU passthrough. GPU passthrough (also known as PCI passthrough or VMDirectPath) assigns the entire physical GPU to a single virtual machine, bypassing the hypervisor's abstraction layer. This gives the VM direct hardware access for maximum graphics performance, which is essential for CAD rendering. On a Type 2 hypervisor (e.g., Hyper-V on Windows Server), this is achieved via Discrete Device Assignment (DDA) or SR-IOV, allowing the VM to use native GPU drivers without emulation.

Answer

Shared GPU acceleration

Answer

Virtual GPU (vGPU)

Answer

RemoteFX

Question 10

A laser printer is printing pages with dark vertical streaks. The technician replaces the toner cartridge and the imaging drum, but the streaks persist. Which of the following components should the technician check NEXT?

Accepted Answer

Transfer roller. The transfer roller is responsible for transferring toner from the imaging drum to the paper. If the transfer roller is damaged, contaminated, or worn, it can cause uneven charge distribution, leading to dark vertical streaks on the printed page. Since replacing the toner cartridge and imaging drum did not resolve the issue, the transfer roller is the next likely culprit.

Answer

Fuser assembly

Answer

Paper tray rollers

Answer

Laser scanner mirror

Question 11

A small business currently has a single router that provides internet access and DHCP services. The owner wants to add a second wireless router to extend Wi-Fi coverage to a far part of the building. The technician connects the WAN port of the new router to a LAN port on the existing router using a patch cable. Wireless clients can connect to the new router's SSID and obtain IP addresses, but they cannot access the internet or any resources on the main LAN. Which of the following is the most likely cause?

Accepted Answer

The new router is performing NAT, causing double NAT. When the WAN port of the new router is connected to a LAN port of the existing router, the new router treats the existing network as its 'internet' side and performs Network Address Translation (NAT) on all traffic from its wireless clients. This creates a double NAT scenario: the new router translates private IPs to its own WAN IP (typically 192.168.1.x), and then the existing router translates that again to its public IP. The result is that return traffic cannot be properly routed back to the wireless clients, breaking internet and LAN access.

Answer

The new router's wireless security is set to WPA3

Answer

The existing router's DHCP pool is exhausted

Answer

The patch cable is a crossover cable

Question 12

A network technician is troubleshooting a new fiber optic link between two buildings. The link is down. The technician uses a visual fault locator (VFL) at the transmitting end and observes a faint red glow at the patch panel in the receiving building. What does this indicate?

Accepted Answer

The fiber has a break or severe bend. A faint red glow from a visual fault locator (VFL) at the far-end patch panel indicates that the visible laser light is leaking through a break or severe bend in the fiber. VFLs inject a high-power visible red laser (typically 650 nm) into the core; if the fiber is intact, the light should be contained and invisible at the far end. A faint glow means the light is escaping from a damaged point, confirming a physical fault that prevents proper data transmission.

Answer

The fiber connectors are dirty

Answer

The transmitter power is too low

Answer

The connectors are mismatched (e.g., SC vs. LC)

Question 13

A company wants to deploy a custom web application in the cloud. They need full control over the operating system and software stack, including the ability to install and configure the web server, database, and security patches. They do not want to manage the underlying physical hardware or hypervisor. Which cloud service model best meets their 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, middleware, and applications while the cloud provider manages the underlying physical hardware and hypervisor. This matches the requirement for full OS and software stack control without managing physical infrastructure.

Answer

Platform as a Service (PaaS)

Answer

Software as a Service (SaaS)

Answer

Desktop as a Service (DaaS)

Question 14

A company wants to ensure that its cloud-based application remains available even if an entire data center goes offline. The company deploys the application across multiple geographically separate data centers operated by the cloud provider. Which cloud concept is the company implementing?

Accepted Answer

Fault tolerance. Fault tolerance is the correct answer because the company is designing the application to continue operating without interruption even if an entire data center fails. This is achieved by deploying redundant instances across multiple geographically separate data centers, ensuring that no single point of failure can bring down the application. Unlike high availability, which minimizes downtime, fault tolerance aims for zero downtime by maintaining active copies in separate failure domains.

Answer

High availability

Answer

Load balancing

Answer

Elasticity

Question 15

A network technician is installing a new IP security camera that requires Power over Ethernet (PoE) IEEE 802.3af. The technician runs a new Cat6 Ethernet cable between a PoE switch port and the camera. The switch is PoE-enabled and configured to supply power. When the camera is connected, it does not power on. The technician tests the cable with a continuity tester, and all eight wires pass. Which of the following is the most likely cause of the issue?

Accepted Answer

The switch port is administratively disabled in the switch configuration.. The most likely cause is that the switch port is administratively disabled. Even though the switch is PoE-enabled and the cable passes continuity, if the port is in a shutdown state (e.g., via the 'shutdown' command in Cisco IOS), it will not provide power or data to the camera. The technician should verify the port status with 'show interfaces' or 'show running-config' and enable it with 'no shutdown'.

Answer

The cable run exceeds the maximum length for PoE (100 meters).

Answer

The camera requires PoE+ (802.3at) and will not work with standard PoE.

Answer

The cable is terminated with T568A on one end and T568B on the other.
