FC0-U61 IT Concepts and Terminology Practice Test 2 — 15 Questions

Question 1

A small business has a single server running Windows Server 2019 that acts as a domain controller, file server, and DHCP server. The server has a single network interface with IP address 192.168.1.10/24. The office has 30 client computers running Windows 10. All clients obtain IP addresses automatically. The network uses a single unmanaged switch. The internet connection is provided by a cable modem with IP 192.168.1.1. The server is configured with a static IP of 192.168.1.10, and the DHCP scope is 192.168.1.100-192.168.1.200. Recently, users have reported that they cannot access the internet. The technician checks that the cable modem is online and that the server can ping the modem. The technician runs 'ipconfig /all' on a client and sees: IP: 192.168.1.101, Subnet: 255.255.255.0, Default Gateway: 192.168.1.10, DNS: 192.168.1.10. The client can ping the server (192.168.1.10) but cannot ping the modem (192.168.1.1). What is the most likely cause?

Accepted Answer

Change the DHCP scope option for the default gateway to 192.168.1.1. The correct answer is D. The DHCP scope is configured with the default gateway option set to 192.168.1.10 (the server's IP), but the actual default gateway for internet access is the cable modem at 192.168.1.1. Since clients receive their gateway via DHCP, they are sending all off-subnet traffic to the server, which is not configured to route to the internet. Changing the DHCP scope option for the default gateway to 192.168.1.1 will allow clients to route internet traffic through the modem.

Answer

Disable the Windows Firewall on the server to allow traffic

Answer

Replace the cable modem as it is not routing traffic correctly

Answer

Configure the DNS server to forward queries to 8.8.8.8

Question 2

A hospital uses a legacy application that runs on a Windows 7 workstation. The application stores patient data in a local database. The IT department is migrating all workstations to Windows 10. The legacy application is not compatible with Windows 10. The hospital needs to continue using the application and ensure patient data is accessible from the new workstations. The application requires a dedicated workstation due to licensing. Which solution should the IT department implement?

Accepted Answer

Install a virtual machine with Windows 7 on a Windows 10 workstation and run the application in the VM. Option C is correct because running a virtual machine (VM) with Windows 7 on a Windows 10 workstation allows the legacy application to operate in its native OS environment without hardware compatibility issues. The VM isolates the application and its local database, ensuring patient data remains accessible from the new workstation while satisfying the dedicated workstation licensing requirement by using a single physical host.

Answer

Keep the old Windows 7 workstation on the network for the application and use it as is

Answer

Upgrade the legacy application to a version that supports Windows 10

Answer

Set up a dual-boot configuration on the new workstation to boot into Windows 7 when needed

Question 3

Which TWO of the following are examples of volatile memory?

Accepted Answer

RAM. RAM (Random Access Memory) is volatile because it requires constant electrical power to retain data; once the system is powered off, all stored information is lost. This characteristic makes RAM ideal for temporary storage of actively used data and program instructions during operation.

Answer

Hard Drive

Answer

SSD

Answer

ROM

Question 4

A user reports being unable to access the internet, but can reach other devices on the local network. Based on the exhibit, what is the most likely cause?

Accepted Answer

The DNS server is not reachable.. Since the user can reach other devices on the local network but cannot access the internet, the issue is likely with the default gateway or DNS resolution. Option D is correct because if the DNS server is unreachable, the user can still communicate with local devices via IP addresses but cannot resolve domain names to access internet resources. The exhibit likely shows a valid IP address and subnet mask, but the DNS server address is missing or incorrect, preventing name resolution.

Answer

The default gateway is missing.

Answer

The IP address is in the wrong subnet.

Answer

The subnet mask is incorrect.

Question 5

You are a support technician for a small company. An employee reports that their desktop computer will not turn on. You have verified that the power cable is securely connected to both the computer and the wall outlet. When you press the power button, you hear a faint clicking sound but the computer does not start. The power supply fan does not spin, and there are no lights on the motherboard. You have tested the wall outlet with a known working device and it provides power. What is the most likely cause of the issue?

Accepted Answer

The power supply is faulty.. The correct answer is C because the symptoms—faint clicking sound, no fan spin, no motherboard lights, and confirmed wall outlet power—strongly indicate a power supply failure. The clicking sound often comes from a relay or overload protection circuit inside the PSU attempting to start but failing due to internal component damage or short circuit. A faulty power supply cannot deliver the necessary voltages (e.g., +3.3V, +5V, +12V) to power the system, explaining the complete lack of activity.

Answer

The CPU is overheated.

Answer

The power button is not connected properly.

Answer

The motherboard has failed.

Question 6

A user is trying to install a new printer driver on a Windows 10 workstation but receives an error stating the driver is not signed. Which security concept is most directly involved?

Accepted Answer

Authentication. Driver signing is a mechanism that verifies the publisher's identity and ensures the driver has not been tampered with. This directly relates to integrity, not authentication. Authentication is about verifying identity (e.g., user login), but the error here is about the driver's digital signature, which protects integrity. Option D is incorrect because authentication is not the primary concept involved.

Answer

Availability

Answer

Integrity

Answer

Confidentiality

Question 7

A technician is troubleshooting a slow network and suspects a loop. Which command-line tool should the technician use to identify the loop?

Accepted Answer

ping -t 1 192.168.1.1. Option C is correct because the `ping -t 1 192.168.1.1` command sends ICMP echo requests with a Time-to-Live (TTL) value of 1. If a network loop exists, the packet will be forwarded in a cycle, and each hop decrements the TTL. When the TTL reaches 0, the router discards the packet and sends an ICMP Time Exceeded message back. By observing repeated Time Exceeded responses from the same or multiple IPs, the technician can identify the loop's location.

Question 8

An IT department is planning a new server deployment. They need to ensure that if one server fails, another can take over with minimal downtime. Which concept describes this requirement?

Accepted Answer

Fault tolerance. The requirement describes a system where a secondary server automatically takes over with minimal downtime upon failure of the primary server. This is the definition of fault tolerance, which uses redundant components (e.g., dual power supplies, RAID, or clustered servers) to ensure continuous operation without interruption. High availability (option C) is related but focuses on maximizing uptime through redundancy and failover, whereas fault tolerance specifically aims for zero or near-zero downtime by masking failures completely.

Answer

Disaster recovery

Answer

Scalability

Answer

High availability

Question 9

A help desk technician receives a ticket that a user cannot access a shared folder. The technician verifies the network cable is connected and the user can ping the server. What should the technician check next?

Accepted Answer

Check the permissions on the shared folder. Since the user can ping the server, Layer 3 (network layer) connectivity is confirmed, ruling out issues with the network cable, DNS resolution, and default gateway. The inability to access a shared folder despite successful ping points to a permissions issue at the file system or share level, which is independent of basic network connectivity. Checking the permissions on the shared folder is the logical next step to verify that the user's account has the necessary read/write access rights.

Answer

Restart the user's computer

Answer

Check the DNS server settings

Answer

Check the default gateway configuration

Question 10

Drag and drop the steps to boot a computer into Safe Mode in Windows 10 into the correct order.

Question 11

Drag and drop the steps to change the desktop background in Windows 10 into the correct order.

Question 12

Match each network protocol to its well-known port number.

Question 13

Match each security concept to its definition.

Question 14

A user reports that their computer is slow. Which of the following is the BEST first step to troubleshoot?

Accepted Answer

Check Task Manager for high resource usage.. Option C is correct because the first step in troubleshooting a slow computer is to identify the cause of the performance issue. Task Manager provides real-time data on CPU, memory, disk, and network utilization, allowing you to pinpoint which process or resource is being overused. This diagnostic approach follows the standard troubleshooting methodology of gathering information before making changes.

Answer

Replace the hard drive.

Answer

Upgrade the RAM.

Answer

Reinstall the operating system.

Question 15

A database administrator needs to ensure that a transaction either fully completes or is fully rolled back. Which database property guarantees this?

Accepted Answer

Atomicity. Atomicity ensures that a transaction is treated as a single, indivisible unit of work: either all of its operations are committed successfully, or none are applied, and the database is rolled back to its previous state. This property directly guarantees the 'all or nothing' behavior required by the database administrator. In SQL databases, atomicity is typically enforced through transaction control statements like BEGIN TRANSACTION, COMMIT, and ROLLBACK, with the database engine managing undo logs to reverse partial changes if a failure occurs.

Answer

Isolation

Answer

Durability

Answer

Consistency
