220-1101 Practice Test 2 — 10 Questions

Question 1

A company uses a private cloud with 10 virtual servers running on a single hypervisor host. The VMs are configured with dynamic memory allocation. Recently, performance has degraded, and the hypervisor shows 90% memory utilization. The IT team wants to add two more VMs without purchasing additional hardware. Which of the following is the most likely limiting factor?

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

Accepted Answer

The total physical RAM installed in the host. The hypervisor shows 90% memory utilization, and dynamic memory allocation allows VMs to share physical RAM. Adding two more VMs without increasing physical memory will likely exhaust the host's RAM, causing excessive swapping or out-of-memory conditions. This makes total physical RAM the most likely limiting factor.

Answer

The hypervisor's CPU core count

Answer

The storage I/O bandwidth

Answer

The network interface card speed

Question 2

A user reports that the network printer in the office is no longer accessible from any workstation after an overnight power outage. The printer has a static IP address of 192.168.1.50. The technician checks the printer and sees it is powered on, the network cable is connected, and the link light on both the printer and the switch port is solid. The technician pings 192.168.1.50 from a workstation, but there is no reply. The technician checks the printer's network settings from its front panel and sees that the IP address is 169.254.10.25. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The printer lost its static IP configuration due to the power outage.. The printer's IP address changed from the static 192.168.1.50 to an Automatic Private IP Addressing (APIPA) address in the 169.254.0.0/16 range. This occurs when a device configured for DHCP fails to obtain a lease from a DHCP server, which can happen after a power outage if the printer's non-volatile RAM (NVRAM) lost its static IP configuration and it reverted to DHCP. Since the printer is now on a different subnet, workstations cannot reach it, explaining the failed ping.

Answer

The printer's network adapter is faulty.

Answer

The switch port is configured with the wrong VLAN.

Answer

The DNS server is not resolving the printer's hostname.

Question 3

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 4

A company runs a web application on a virtual machine in a public cloud. The application experiences predictable spikes in traffic every day between 12:00 PM and 1:00 PM. The company wants to ensure consistent performance during these spikes without permanently upgrading the VM's resources. Which of the following cloud characteristics should the administrator configure?

Accepted Answer

Rapid elasticity. Rapid elasticity is the correct cloud characteristic because it allows the virtual machine's resources (e.g., CPU, RAM) to automatically scale up during the predictable 12:00 PM to 1:00 PM traffic spike and scale back down afterward, ensuring consistent performance without permanently upgrading the VM. This is a core feature of cloud computing defined by NIST SP 800-145, enabling dynamic provisioning and de-provisioning of resources to match demand.

Answer

Measured service

Answer

Resource pooling

Answer

On-demand self-service

Question 5

A technician is troubleshooting a desktop PC that fails to boot. When the power button is pressed, the system powers on for approximately 5 seconds, then shuts down and immediately restarts, repeating this cycle. The technician has replaced the power supply, reseated all components, and verified there are no loose screws or shorts. The motherboard has diagnostic LEDs, and the CPU LED glows solid red when the system attempts to start. The CPU is an Intel Core i7-12700K (LGA1700) installed in a compatible motherboard. The cooler is properly mounted with thermal paste applied. Which of the following is the MOST likely cause?

Accepted Answer

The motherboard BIOS version does not support the installed CPU.. The CPU LED glowing solid red indicates a CPU-related fault. Since the technician has already replaced the power supply, reseated components, and verified proper cooler mounting, the most likely cause is that the motherboard's BIOS version predates the microcode required for the Intel Core i7-12700K (Alder Lake, LGA1700). Many LGA1700 motherboards require a BIOS update to support 12th-gen CPUs; without it, the system fails to initialize the CPU, leading to the observed power cycle.

Answer

The CPU cooler is not making sufficient contact with the CPU.

Answer

The RAM modules are not fully seated in the correct slots.

Answer

The power supply unit is delivering insufficient wattage on the +12V rail.

Question 6

A technician sets up a small office network. The router is configured with DHCP providing addresses in the 192.168.1.0/24 range. A new employee's laptop obtains an IP address of 192.168.1.50, subnet mask 255.255.255.0, and default gateway 192.168.1.1. The laptop can ping other local workstations and the router (192.168.1.1), but cannot access any external websites by domain name or IP address. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The router's WAN connection is not properly configured or is down.. The laptop can ping the local router (192.168.1.1) and other local workstations, which confirms that the laptop's IP configuration (address, subnet mask, default gateway) is correct and that the local LAN is functioning. However, the inability to reach any external websites by either domain name or IP address indicates that the router cannot forward traffic beyond its local subnet. The most likely cause is that the router's WAN connection is not properly configured or is down, preventing any outbound traffic from reaching the internet.

Answer

The laptop's DNS server configuration is incorrect.

Answer

The default gateway is not set correctly on the laptop.

Answer

A firewall on the router is blocking all outbound traffic from the laptop.

Question 7

A system administrator is configuring a virtual machine (VM) on a VMware ESXi host. The VM runs a critical database application that requires a guaranteed minimum amount of memory to perform well. The host has memory overcommitment enabled. Which setting should the administrator configure to ensure the VM always has at least 4 GB of physical memory available?

Accepted Answer

Memory reservation. A memory reservation guarantees that the ESXi host will allocate at least the specified amount of physical memory to the VM, even when memory overcommitment is enabled. This ensures the critical database application always has a minimum of 4 GB of physical RAM available, preventing performance degradation due to contention.

Answer

Memory limit

Answer

Memory ballooning

Answer

Swap file size

Question 8

A user's Android smartphone will not charge when plugged into the wall charger. The technician has already verified the charger and cable work with another phone, cleaned the charging port with compressed air, and performed a soft reset. Which of the following should the technician try NEXT?

Accepted Answer

Check the charging port for compacted debris with a flashlight and non-conductive tool. Since the charger and cable are verified working and a soft reset has been performed, the most likely remaining issue is physical debris deep inside the charging port that compressed air alone could not dislodge. Using a flashlight and a non-conductive tool (e.g., plastic or wooden pick) allows the technician to safely inspect and remove compacted debris without shorting the port's pins, which is a common cause of intermittent or failed charging on Android devices.

Answer

Replace the battery

Answer

Replace the charging port assembly

Answer

Perform a factory reset

Question 9

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 10

A network administrator is setting up a wired network for a small office that has 25 workstations, 2 file servers, and a router with 4 LAN ports. The office uses IP-based printers and VoIP phones. The administrator wants to minimize broadcast traffic and improve network performance by separating the workstations from the servers and printers. Which of the following is the BEST solution?

Accepted Answer

Use a single managed switch and configure port-based VLANs. A managed switch with port-based VLANs allows the network administrator to logically segment the workstations from the servers and printers on the same physical switch, reducing broadcast domain size and improving performance. VLANs isolate broadcast traffic to only the ports within the same VLAN, so workstations do not see broadcasts from servers or printers, and vice versa. This solution uses a single switch, which is cost-effective and simple to manage, while meeting the requirement to minimize broadcast traffic without needing multiple routers.

Answer

Connect all devices to a single unmanaged switch

Answer

Connect all devices to a hub instead of a switch

Answer

Use multiple routers to separate networks
