220-1101 Practice Test 33 — 15 Questions

Question 1

A company hosts a critical e-commerce application in a public cloud. The application is deployed across two availability zones in the same region. The cloud provider automatically monitors the health of the application in each zone and, if one zone becomes unavailable, all traffic is directed to the healthy zone without requiring any manual intervention. This setup BEST demonstrates which cloud characteristic?

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

Accepted Answer

High availability. This setup demonstrates high availability because the application is designed to remain accessible despite the failure of an entire availability zone. The cloud provider's automatic health monitoring and traffic rerouting ensure that if one zone goes down, all traffic is seamlessly directed to the healthy zone without manual intervention, minimizing downtime. This aligns with the core goal of high availability: eliminating single points of failure to maintain service continuity.

Answer

Elasticity

Answer

Scalability

Answer

Resource pooling

Question 2

A company uses a cloud platform where users can provision virtual servers and storage through a web portal without any human interaction with the IT staff. This capability is an example of which cloud computing characteristic?

Accepted Answer

On-demand self-service. The scenario describes users provisioning virtual servers and storage through a web portal without any human interaction with IT staff. This directly aligns with the NIST definition of on-demand self-service, where a consumer can unilaterally provision computing capabilities as needed automatically without requiring human interaction with each service provider. The key phrase 'without any human interaction' is the hallmark of this characteristic.

Answer

Broad network access

Answer

Resource pooling

Answer

Measured service

Question 3

A technician is troubleshooting a user's wired desktop that can access local network shares and printers but cannot reach any internet websites. The technician pings the default gateway successfully. Which of the following is the most likely cause of this issue?

Accepted Answer

DNS server configuration is incorrect or the DNS server is unreachable. The user can access local resources (shares, printers) and successfully ping the default gateway, which confirms that Layer 2/3 connectivity, IP addressing, and routing are functional. However, the inability to reach internet websites while local access works points to a name resolution failure. DNS translates domain names to IP addresses; if the DNS server configuration is incorrect or unreachable, the browser cannot resolve website names, even though the network path to the internet is intact.

Answer

IP address conflict with another device on the network

Answer

Faulty network interface card (NIC)

Answer

Incorrect subnet mask on the workstation

Question 4

A user's Android smartphone exhibits a strange charging behavior. When the phone is powered off and connected to the wall charger, it charges normally and the battery percentage increases. However, when the phone is powered on and plugged into the same charger, the device shows the charging icon, but the battery percentage steadily decreases over time, eventually causing the phone to shut down. The user has already tried different charging cables and adapters, and has performed a factory reset. Which component is MOST likely faulty?

Accepted Answer

Battery. The battery is most likely faulty because it can hold a charge when the phone is off (minimal current draw) but fails under the higher load of the powered-on system. A degraded battery's internal resistance increases, causing voltage sag under load, which the PMIC interprets as a low charge state, leading to a net discharge despite the charger being connected.

Answer

Charging port / USB connector

Answer

Power management integrated circuit (PMIC)

Answer

Operating system battery calibration

Question 5

A user reports that a laser printer is displaying a 'Paper Jam' error even though no paper is visibly jammed inside the printer. The technician has removed all paper trays and checked the fuser area, rollers, and output bin, but finds no crumpled or stuck paper. Which of the following is the MOST likely cause of this error?

Accepted Answer

A stuck paper jam sensor. A stuck paper jam sensor can cause a false 'Paper Jam' error because the sensor remains in the triggered position even when no paper is present. The printer's firmware interprets the sensor's state as a jam, halting operation. Since the technician has visually confirmed no paper in all common areas, the sensor itself is the most likely culprit.

Answer

A faulty fuser heating element

Answer

A worn transfer roller

Answer

Outdated printer firmware

Question 6

A technician builds a PC with a CPU that supports PCIe 4.0, a motherboard with PCIe 4.0-capable slots, and a PCIe 4.0 GPU. After installation, the GPU is running at PCIe 3.0 speeds according to GPU-Z. The technician has updated the motherboard BIOS to the latest version and installed the latest chipset drivers. Which of the following is the MOST likely cause of the GPU not running at PCIe 4.0?

Accepted Answer

A. The GPU is installed in a secondary PCIe slot that is limited to PCIe 3.0. The most likely cause is that the GPU is installed in a secondary PCIe slot that is limited to PCIe 3.0. Even though the motherboard supports PCIe 4.0, not all slots on the board are necessarily wired for PCIe 4.0; secondary slots often run at PCIe 3.0 or lower due to chipset lane limitations. Installing the GPU in the primary (top) x16 slot, which is directly connected to the CPU, would allow PCIe 4.0 speeds.

Answer

B. The GPU firmware (vBIOS) is outdated

Answer

C. The power supply unit does not provide enough wattage

Answer

D. The GPU is not fully seated in the PCIe slot

Question 7

A technician is replacing the battery in an Android smartphone. Which of the following is the MOST important step to prevent damage to the SIM card during the repair?

Accepted Answer

Remove the SIM card tray. The SIM card is a delicate component that can be easily damaged if the phone is opened without first removing it. By taking out the SIM card tray, you eliminate the risk of bending or scratching the SIM card when prying the battery or handling internal components. This step is critical because the SIM card sits on a flexible tray that can snap or warp under pressure, potentially rendering the card unusable.

Answer

Power off the phone

Answer

Use a plastic spudger to pry the battery

Answer

Disconnect the screen flex cable

Question 8

A user's iPhone 12 has no sound from the speaker during phone calls, but the earpiece works normally. The user has confirmed that the volume is turned up and the silent switch is not enabled. The technician has performed a restart and updated iOS to the latest version. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The speaker grille is blocked or the speaker is faulty. The iPhone 12 uses a separate earpiece speaker for phone calls and a bottom-firing speaker for media and speakerphone. Since the earpiece works but the main speaker has no sound during calls, the issue is isolated to the bottom speaker grille being blocked (e.g., by debris or case obstruction) or the speaker itself being faulty. Restarting and updating iOS rules out software glitches, making hardware blockage or failure the most likely cause.

Answer

The Lightning port is clogged

Answer

The SIM card is damaged

Answer

The screen is cracked

Question 9

Employees in a small office report that their wired network connections become extremely slow or drop every time the office microwave oven is used. The microwave is located in the breakroom, and the network cables for the cubicles run through the ceiling directly above the breakroom. The cables currently installed are unshielded twisted pair (UTP) Cat5e. The technician has confirmed the microwave is not physically damaging the cables and that the router and switch are not overheating. Which of the following solutions would MOST effectively resolve the intermittent network issues?

Accepted Answer

Replace the UTP Cat5e cables with STP Cat6a cables. The intermittent network slowdowns and drops are caused by electromagnetic interference (EMI) generated by the microwave oven, which radiates strongly in the 2.4 GHz range. UTP Cat5e cables lack shielding and are susceptible to this EMI, especially when running through the ceiling directly above the microwave. Replacing them with STP Cat6a cables provides foil or braided shielding that blocks EMI, preserving signal integrity and resolving the issue.

Answer

Upgrade the network switches to models that support QoS (Quality of Service)

Answer

Install ferrite chokes on both ends of each network cable

Answer

Replace the RJ45 wall jacks with shielded Cat6 jacks

Question 10

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 11

A network technician is troubleshooting inter-VLAN routing. Clients on VLAN 10 (192.168.10.0/24) cannot communicate with servers on VLAN 20 (192.168.20.0/24). The router has subinterfaces configured for both VLANs and an ACL that permits all traffic between them. The router connects to a Layer 2 switch via a single cable. The switch port connecting to the router is configured as an access port in VLAN 10. Which of the following is the MOST likely cause of the communication failure?

Accepted Answer

The switch port connecting to the router is configured as an access port instead of a trunk. The router connects to the switch via a single cable, and the switch port is configured as an access port in VLAN 10. For inter-VLAN routing using router-on-a-stick, the switch port must be a trunk port that carries multiple VLANs (802.1Q tagged). An access port can only carry untagged traffic for a single VLAN, so frames from VLAN 20 cannot reach the router's subinterface, breaking communication.

Answer

The ACL is blocking traffic between VLAN 10 and VLAN 20

Answer

The router's subinterface for VLAN 20 has an incorrect IP address

Answer

The switch is not configured with VLAN 20

Question 12

A company runs a Type 1 hypervisor with several production virtual machines (VMs). The physical host has 64 GB of RAM. The administrator observes that the host’s memory usage is consistently at 95%, leaving no free memory for a new VM that needs 8 GB. However, the existing VMs are only using about 50% of their allocated memory. Which hypervisor technology can the administrator use to run the new VM without adding physical RAM?

Accepted Answer

Memory overcommitment with ballooning. Memory overcommitment with ballooning allows the hypervisor to reclaim unused memory from running VMs by using a balloon driver that inflates inside the guest OS, forcing the guest to release memory pages back to the hypervisor. This reclaimed memory can then be allocated to the new VM without adding physical RAM. The scenario describes existing VMs using only 50% of their allocated memory, making ballooning an ideal solution to free up the needed 8 GB.

Answer

Thin provisioning

Answer

vMotion

Answer

Memory mirroring

Question 13

A user reports that they can access internal company web servers by IP address (e.g., http://10.0.1.50) but not by hostname (e.g., http://intranet). Other users on the same network can access the intranet by hostname without issue. The technician checks the computer's IP settings and sees that the DNS server address is manually set to 8.8.8.8. Which of the following is the MOST likely cause?

Accepted Answer

The computer is using an external DNS server that cannot resolve internal hostnames. The computer has its DNS server manually set to 8.8.8.8, which is a public external DNS server operated by Google. External DNS servers like 8.8.8.8 have no records for internal private hostnames (e.g., 'intranet'), so they cannot resolve them. Since the user can access internal servers by IP address but not by hostname, and other users on the same network can resolve the hostname (likely using an internal DNS server), the issue is specifically that this computer is using an external DNS server that cannot resolve internal hostnames.

Answer

The computer's subnet mask is incorrect

Answer

The internal DNS server is unreachable

Answer

The DHCP scope is exhausted

Question 14

A user reports that their iPhone is not recognized by a Windows computer when connected via USB. The user has tried three different USB cables, all of which allow the phone to charge normally. The user also tested another iPhone with the same computer and it was recognized. The iPhone's 'Trust This Computer' prompt appeared and was accepted. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The Lightning port on the iPhone has damaged data pins.. The fact that the iPhone charges normally but is not recognized by the computer indicates that the power pins in the Lightning connector are functioning, but the data pins are damaged or obstructed. Since another iPhone is recognized on the same computer, the issue is isolated to the original iPhone's Lightning port. The 'Trust This Computer' prompt appearing and being accepted confirms that the software trust relationship is not the problem, further pointing to a hardware data pin failure.

Answer

The iPhone's battery needs to be replaced.

Answer

The iPhone's operating system is corrupt.

Answer

The iPhone's display assembly is malfunctioning.

Question 15

A technician is troubleshooting a server that randomly shuts down after running for about 30 minutes. The server has dual power supplies and is connected to a UPS. The technician has already replaced the CPU cooler and verified that all fans are spinning. The temperature readings for the CPU and motherboard are within normal range. Which component should the technician check NEXT?

Accepted Answer

The power supply voltage rails. Random shutdowns after a consistent runtime (30 minutes) often indicate a failing power supply that cannot maintain stable output under sustained load. The technician has already ruled out overheating by replacing the CPU cooler, verifying fan operation, and confirming normal temperature readings. Checking the power supply voltage rails with a multimeter or PSU tester can reveal sagging voltages or ripple that cause intermittent shutdowns, even when the system appears to run initially.

Answer

The UPS battery

Answer

The thermal paste application

Answer

The RAM modules
