A network administrator wants to place the accounting department and the sales department on separate broadcast domains using a single managed switch, without buying additional hardware. Which feature should be configured to accomplish this?
A company wants employees at a remote branch office to securely access resources on the main corporate LAN over the public internet as if they were locally connected. Which technology should the technician implement to meet this requirement?
A technician is working at a user's desk when the desktop PC suddenly emits a sharp burning smell along with a faint crackling sound, and a thin wisp of smoke rises from the rear of the case near the power supply. What should the technician do FIRST?
A workstation that has been in service for six years now randomly locks up and sometimes fails to POST. During a visual inspection, a technician notices several small cylindrical components near the CPU socket have domed, bulging tops with brownish residue leaking from the vents. What is the MOST likely cause of the instability?
A technician installs a Type 2 hypervisor on a modern desktop to run a 64-bit guest OS for testing. The host has 32 GB of RAM and ample disk space, but when the technician tries to create the virtual machine, the hypervisor reports that hardware virtualization is unavailable and refuses to start 64-bit guests. What should the technician do first to resolve this?
A technician needs to run three virtual machines simultaneously on a workstation using a type 2 hypervisor. Each VM requires 4 GB of RAM to run its guest OS, and the host operating system needs at least 8 GB to remain responsive. What is the minimum amount of physical RAM the workstation should have to support this configuration?
A technician uses a client-side hypervisor to test a new software patch on a virtual machine. Before applying the patch, the technician wants a quick way to capture the VM's current state so it can be instantly restored if the patch causes problems, without cloning the entire virtual disk. Which hypervisor feature should be used?
A security analyst runs several virtual machines on a workstation to detonate suspicious files. She wants each VM to have full network functionality among the VMs so she can watch how malware attempts to spread laterally, but she must guarantee that no traffic ever reaches the physical LAN or the internet. Which hypervisor network setting should she assign to these VMs?
A user reports that every time their desktop is unplugged overnight, the system clock resets to a date in the past and the BIOS/UEFI prompts them to re-enter setup or press F1 to continue booting. The computer otherwise runs normally once it starts. Which component should the technician replace to resolve this issue?
Several regional hospitals want to share a common cloud platform that meets strict healthcare compliance requirements. Each hospital is a separate organization, but they agree to jointly fund and govern the shared infrastructure so costs and regulatory controls are distributed among the participating members. Which cloud deployment model best fits this arrangement?
A technician is setting up a small office where the existing 24-port switch is fully occupied, but six more wired workstations must be added. The technician has a second switch available. Which device is designed to interconnect the two switches and forward traffic between all the wired devices on the same local network based on MAC addresses?
A field office is being set up at a remote rural site where no cable, DSL, or fiber service is available from any local provider. The manager needs internet access for email and cloud file storage but has been warned that the chosen connection will have noticeably high latency. Which internet connection type best fits this situation?
A technician is configuring a new workstation on the corporate LAN. The device receives an IPv4 address of 169.254.18.7 and cannot reach any internal servers or the internet, but it can still communicate with a few neighboring devices on the same physical segment. Other workstations on the network are getting addresses in the 10.0.5.x range. What is the MOST likely cause?
A user brings a personal smartphone to the office and needs to configure their corporate email account manually because auto-discovery failed. IT wants incoming messages to remain stored on the mail server so the user can also access them from a desktop client at their workstation. Which incoming protocol and port combination should the technician configure?
A technician is building a workstation with a liquid all-in-one (AIO) CPU cooler. The motherboard has several 4-pin fan headers labeled CPU_FAN, CPU_OPT, AIO_PUMP, and SYS_FAN. To ensure the cooler's pump runs at a constant full speed and the system does not trigger a fan-error warning at boot, where should the technician connect the pump's power lead?
A technician installs four identical 8 GB DIMMs (32 GB total) into a workstation with four memory slots. After booting, the BIOS/UEFI and operating system report only 16 GB of usable RAM. All modules test good individually in a known-working slot, and the board's manual lists a maximum supported capacity of 128 GB. What is the MOST likely cause?
A technician assembles a new workstation. When they press the power button, the case fans spin briefly and the RGB lighting flashes, but the system fails to POST and no video appears. The 24-pin motherboard connector is fully seated and the GPU has its PCIe power cables attached. What is the MOST likely cause of this failure?
A technician is installing a new AMD Ryzen processor into a desktop motherboard. The CPU has an array of metal pins protruding from its underside, and there is a small gold triangle printed on one corner of the chip. What is the correct action to ensure proper installation?
A technician is called to a workstation that powers on normally but shuts down abruptly within a few minutes of heavy CPU usage. UEFI hardware monitoring shows the CPU temperature climbing rapidly toward its thermal limit before shutdown. The CPU fan is spinning at full speed, and all case fans function. Upon inspection, the heatsink is firmly seated but was recently removed and reinstalled by another technician. What is the MOST likely cause?
A hospital is deploying a group of virtualization hosts that need shared, high-speed block-level access to a centralized disk array. The storage traffic must be isolated from the regular user LAN to guarantee low latency for the virtual machines' disk operations. Which type of network should the technician recommend to meet these requirements?
A technician arrives at a small office where several newly powered-on workstations cannot obtain a network connection, while machines that were already running work fine. On the router's DHCP status page, the technician sees that all addresses in the configured pool are currently leased out. What is the BEST action to restore connectivity for the new workstations?
A user reports that text and images on their newly connected external monitor appear blurry and stretched, and everything looks slightly fuzzy. The monitor works, colors are correct, and there is no flickering. You confirm the monitor is a 2560x1440 native panel, but Windows display settings currently show it running at 1920x1080. What is the MOST likely cause of the blurry appearance?
A user reports they cannot reach any websites by name in their browser, receiving 'server not found' errors. A technician has the user open a command prompt and successfully pings a public website's IP address (142.250.72.14) and receives replies. Pinging the site by its domain name fails with 'could not find host.' Which service is most likely misconfigured or unreachable?
A technician is installing two identical 8GB DDR4 memory modules into a motherboard that has four DIMM slots arranged in two colors: slots 1 and 3 are black, and slots 2 and 4 are blue. The goal is to enable dual-channel memory operation for maximum bandwidth. Where should the technician install the two modules?
A technician must configure a client application to upload sensitive project files to a company server. Company policy requires the file transfer session, including credentials, to be fully encrypted. Which protocol and port should the technician configure?
