220-1201 Practice Test 10 — 10 Questions

Question 1

A technician is configuring a new NAS with four 10 TB hard drives. The customer wants maximum usable capacity with fault tolerance for one drive failure. The technician sets up RAID 5, but after initialization, the usable capacity is only 10 TB instead of the expected 30 TB. What is the most likely cause?

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

Accepted Answer

The array was accidentally configured as RAID 1 (mirroring) across two drives.. RAID 5 with four drives of equal size should yield (n-1) * capacity = 30 TB. A 10 TB result suggests only two drives are being used, possibly due to a misconfiguration like RAID 1 or a stripe set of two drives. This tests RAID 5 capacity calculation and troubleshooting.

Answer

One of the drives is defective and the array is using only three drives.

Answer

The drives are not all the same size; one is 5 TB.

Answer

The RAID controller is using a different stripe size.

Question 2

A technician is tasked with connecting a legacy printer that uses a parallel port to a modern laptop that only has USB ports. Which adapter is required to make this connection work?

Accepted Answer

USB to parallel adapter. A USB to parallel adapter allows a modern laptop to communicate with a legacy parallel printer. This requires an active adapter that converts USB signals to parallel. This tests knowledge of legacy connector adaptation and the need for active conversion.

Answer

USB to serial adapter

Answer

USB to PS/2 adapter

Answer

USB to VGA adapter

Question 3

A customer reports that their laptop can connect to the internet via a wired connection but cannot access any network shares or printers by hostname. They can ping the IP address of the file server. Which network service is most likely misconfigured?

Accepted Answer

DNS. The user can ping the file server by IP address, which confirms that basic IP connectivity (Layer 3) is working. However, they cannot access network shares or printers by hostname, which indicates that the system cannot resolve those hostnames to IP addresses. DNS (Domain Name System) is the service responsible for translating hostnames to IP addresses, so a misconfigured DNS server or client DNS settings would cause exactly this symptom.

Answer

DHCP

Answer

NAT

Answer

ARP

Question 4

A user reports that they can send emails but cannot receive any. The email client is configured with SMTP for outgoing and POP3 for incoming. The server is reachable. Which port is most likely blocked on the firewall for the incoming mail protocol?

Accepted Answer

Port 110. The user can send emails (SMTP works) but cannot receive them, and the incoming protocol is POP3. POP3 uses port 110 by default. Since the server is reachable, a firewall blocking port 110 would prevent the email client from retrieving incoming messages, while SMTP on port 25 remains unaffected.

Answer

Port 25

Answer

Port 443

Answer

Port 53

Question 5

A technician is tasked with connecting a legacy parallel port printer to a modern motherboard that lacks a parallel port header. The motherboard has an LPT header (25-pin) but it is not populated with a bracket. What is the best way to add a parallel port?

Accepted Answer

Purchase an LPT bracket that connects to the motherboard header. The LPT header on the motherboard provides the necessary signals for a parallel port. A bracket with a ribbon cable that connects to this header is the correct solution. A USB-to-parallel adapter would work but may have compatibility issues and is not the best use of the existing header. A PCIe parallel card is an alternative but unnecessary if the header is present.

Answer

Install a USB-to-parallel adapter

Answer

Use a PCIe parallel port expansion card

Answer

Solder wires directly to the motherboard's LPT header pins

Question 6

A client wants to add a second internal hard drive to their desktop for additional storage, but all SATA ports on the motherboard are already used. What is the best solution?

Accepted Answer

Install a SATA expansion card into an available PCIe slot.. An eSATA or SATA expansion card adds more SATA ports via a PCIe slot. USB adapters are slower, and replacing the motherboard is unnecessary. External enclosures are not internal.

Answer

Use a USB-to-SATA adapter and connect the drive externally.

Answer

Replace the motherboard with one that has more SATA ports.

Answer

Use an external hard drive enclosure connected via USB.

Question 7

A user's PC randomly restarts during heavy workloads, such as video rendering. The CPU temperature reads 95°C under load. The heatsink fan is spinning, but the thermal paste appears dry and cracked. What is the most effective first step?

Accepted Answer

Apply new thermal paste between the CPU and heatsink.. Dry, cracked thermal paste loses its ability to transfer heat from the CPU's integrated heat spreader (IHS) to the heatsink base, causing rapid temperature spikes under sustained load. Replacing the paste restores the thermal interface and is the cheapest, most direct fix. The fan is already spinning, so airflow itself is not the immediate problem — the paste is.

Answer

Replace the CPU fan with a higher RPM model.

Answer

Underclock the CPU in BIOS.

Answer

Add an additional case fan.

Question 8

A company uses a PaaS provider to deploy a custom web application. After an update, the application fails to start. The developer checks the code and finds no errors. What is the most likely cause of the failure?

Accepted Answer

The PaaS provider updated the runtime environment, breaking compatibility. In PaaS, the provider manages the runtime environment, including dependencies and configuration. An update may have changed the underlying platform (e.g., runtime version, library) that the application relies on, causing incompatibility. The developer's code is fine, so the issue is environmental.

Answer

The developer's local machine has a different operating system

Answer

The application's database connection string is incorrect

Answer

The cloud provider's physical server has a hardware fault

Question 9

A user says their inkjet printer prints colors that are slightly misaligned, with text appearing blurry. The printer has been used heavily for months. Which component should be checked or calibrated first?

Accepted Answer

The printhead alignment. Misaligned colors and blurry text on an inkjet printer typically indicate that the printhead alignment is off. Most inkjet printers have a built-in alignment utility that prints a test page and adjusts the printhead position. Running this calibration is the standard first step.

Answer

The ink cartridge nozzles

Answer

The paper type setting

Answer

The printer driver version

Question 10

A small business wants to connect two separate office buildings that are 150 meters apart, with no existing data cabling between them. They need a reliable, high-speed connection without running new cables. Which type of network should be implemented?

Accepted Answer

Local Area Network (LAN). A Local Area Network (LAN) is the most appropriate classification. While typically confined to a single building or a small campus, a LAN can be extended to connect two nearby buildings, such as those 150 meters apart, especially when using wireless bridges. This provides a reliable, high-speed connection without the need for new physical cabling. A MAN typically covers a much larger geographic area (several kilometers), and a WAN covers even larger distances. A PAN is for very short-range personal device connections.

Answer

Personal Area Network (PAN)

Answer

Wide Area Network (WAN)

Answer

Metropolitan Area Network (MAN)
