220-1101 Practice Test 5 — 10 Questions

Question 1

A technician is configuring a small office network with a PoE-managed switch and several VoIP phones. All phones are connected and working except one. On the non-working phone, the Ethernet link light is solid on both the phone and the switch port, but the phone's display remains dark and it does not power on. The technician has verified the cable with a tester and it passes. The switch port is enabled and configured for the same VLAN as other working phones. Which of the following is the MOST likely cause?

Accepted Answer

The switch port's PoE power budget has been exceeded.. A PoE-managed switch allocates power from a finite budget. If the total power draw of all connected devices exceeds the switch's PoE power budget, the switch may deny power to additional devices even if the port is administratively enabled and the link is up. The solid Ethernet link light indicates Layer 1 connectivity, but the phone's dark display and lack of power suggest it is not receiving PoE, which is consistent with the switch having exhausted its PoE budget.

Answer

The phone's MAC address is incorrect.

Answer

The cable is a crossover cable.

Answer

The switch port is in a different subnet.

Question 2

A technician is building a new desktop computer for a graphic designer. After installing the motherboard, CPU, RAM, and a high-end discrete GPU, the system powers on (fans spin, LEDs light) but the monitor displays 'No Signal' when plugged into the GPU. The technician verifies the monitor works with another computer. Which of the following should the technician check FIRST?

Accepted Answer

Verify that the PCIe power cables from the power supply are properly connected to the graphics card. The most common cause of a 'No Signal' error when a discrete GPU is installed is that the PCIe power cables from the power supply are not connected or are insufficiently seated. High-end GPUs require dedicated 6-pin or 8-pin PCIe power connectors; without them, the card may power its fans and LEDs via the PCIe slot but cannot initialize the display output. Since the monitor works with another computer, the issue is isolated to the GPU's power delivery, making this the logical first check.

Answer

Reseat the graphics card in the PCIe slot

Answer

Replace the HDMI or DisplayPort cable

Answer

Update the motherboard BIOS to the latest version

Question 3

A technician is building a workstation with a motherboard that has four DIMM slots arranged as two channels (slots 1/2 for channel A, slots 3/4 for channel B). The technician installs two identical 8 GB DDR4 modules in slots 1 and 2. The system POSTs successfully and shows 16 GB of RAM, but subsequent memory benchmarks indicate that the memory bandwidth is only half of the expected value. Which of the following should the technician do to resolve this issue?

Accepted Answer

Move one of the RAM modules to slot 3. The motherboard has two memory channels: channel A (slots 1 and 2) and channel B (slots 3 and 4). Installing both modules in slots 1 and 2 places them on the same channel, which prevents dual-channel interleaving. This halves the memory bandwidth because the CPU can only access one module at a time per channel. Moving one module to slot 3 (channel B) enables dual-channel mode, doubling the effective bandwidth.

Answer

Enable XMP (Extreme Memory Profile) in the BIOS

Answer

Replace both modules with single-rank modules

Answer

Increase the memory voltage in the BIOS

Question 4

A technician is building a workstation for video editing. The motherboard has four DDR4 DIMM slots and supports dual-channel memory. The technician installs two 16 GB modules in slots 1 and 2, and two 8 GB modules in slots 3 and 4. The system boots and recognizes all 48 GB of RAM, but the memory bandwidth is lower than expected. Which of the following is the MOST likely cause?

Accepted Answer

The memory is operating in single-channel mode because the capacities per channel are mismatched.. Dual-channel memory requires matched capacities per channel. With 16 GB in slots 1 and 2 (channel A) and 8 GB in slots 3 and 4 (channel B), the total capacity per channel is 32 GB vs. 16 GB. This mismatch forces the memory controller to fall back to single-channel mode, halving the theoretical bandwidth and causing the lower-than-expected performance.

Answer

The RAM modules are not compatible with the motherboard.

Answer

The CPU does not support 48 GB of RAM.

Answer

The BIOS needs to be updated to enable dual-channel mode.

Question 5

A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?

Accepted Answer

Export the VM as an OVF template and import it into the new hypervisor.. Exporting the VM as an OVF (Open Virtualization Format) template is the most appropriate method because OVF is a hypervisor-agnostic standard that encapsulates the VM's configuration, virtual disks, and metadata. This allows the VM to be imported into VMware vSphere while preserving its installed applications and data, and the export/import process can be performed with minimal downtime by shutting down the VM only during the export phase.

Answer

Perform a physical-to-virtual (P2V) conversion using third-party tools.

Answer

Use live migration (vMotion) to move the VM between hypervisors.

Answer

Rebuild the VM from scratch on the new hypervisor and restore data from backup.

Question 6

A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?

Accepted Answer

File storage. File storage (C) is correct because it provides a shared, persistent file system that can be mounted by multiple VMs simultaneously, typically using NFS or SMB/CIFS protocols. This meets the requirement for persistent storage that survives VM termination and supports concurrent read/write access for a future high-availability configuration.

Answer

Object storage

Answer

Block storage

Answer

Ephemeral storage

Question 7

A company hosts a legacy application on a virtual machine. The application's license is tied to the MAC address of the virtual machine's network interface. The administrator needs to migrate the VM to a different host server without breaking the license. Which of the following virtualization features should the administrator use?

Accepted Answer

MAC address cloning/static assignment. The application's license is tied to the MAC address of the VM's network interface. When a VM is migrated to a different host, the hypervisor typically assigns a new MAC address, which would break the license. By using MAC address cloning or static assignment, the administrator can preserve the original MAC address on the new host, ensuring the license remains valid.

Answer

VLAN tagging

Answer

Jumbo frames

Answer

Network bonding/teaming

Question 8

A company must run a sensitive financial application that requires the application to be hosted on physical servers that are not shared with any other customer. The workload is highly variable and may require large amounts of resources for a few hours at a time. The company wants to minimize costs by paying only for the resources consumed. Which of the following cloud deployment models BEST meets these requirements?

Accepted Answer

Public cloud with dedicated hosts. A public cloud with dedicated hosts meets the requirement for physical server isolation (no resource sharing with other customers) while allowing the company to pay only for the resources consumed. The dedicated host option ensures the sensitive application runs on a physical server dedicated solely to that customer, and the public cloud's pay-as-you-go model supports the highly variable workload without long-term commitments.

Answer

Private cloud

Answer

Hybrid cloud

Answer

Community cloud

Question 9

A company subscribes to a cloud service that allows them to select a set amount of virtual CPU cores, RAM, and storage for their instances. They are billed monthly based on the total resources used, regardless of how many times they change the configuration. This billing model BEST represents which cloud computing characteristic?

Accepted Answer

Measured service. The billing model described charges based on the total resources (vCPU, RAM, storage) consumed over the month, regardless of configuration changes. This is the definition of measured service, where cloud resource usage is metered, monitored, and billed according to actual consumption. The key is that the cost is directly tied to the measured quantity of resources used, not to the frequency or method of provisioning.

Answer

On-demand self-service

Answer

Rapid elasticity

Answer

Resource pooling

Question 10

A business uses a cloud service that automatically increases the number of virtual servers during peak traffic hours and decreases them during low usage, all without manual intervention. The policy is predefined in the cloud management console. This scenario best exemplifies which characteristic of cloud computing?

Accepted Answer

Rapid elasticity. Rapid elasticity is the correct characteristic because the cloud service automatically scales virtual server resources up and down based on predefined policies, matching demand without manual intervention. This dynamic scaling—adding instances during peak traffic and removing them during low usage—is the core definition of rapid elasticity in cloud computing, as it allows resources to expand and contract elastically to meet workload changes.
