FC0-U71 Practice Test 35 — 15 Questions

Question 1

A user installed a new photo editing application. After opening it, the user receives an error that the application cannot find a required DLL file. Which of the following is the MOST likely cause?

Accepted Answer

The application did not install all necessary components.. A DLL (Dynamic Link Library) file is a shared code library that applications call at runtime. If the application installer did not copy all required DLLs to the system (e.g., missing Visual C++ Redistributable or a specific runtime component), the application will fail with a 'DLL not found' error. This is the most common cause because the installation process was incomplete or corrupted, not because of hardware or driver issues.

Answer

The application configuration file is corrupted.

Answer

The computer does not have enough RAM to run the application.

Answer

The graphics driver is outdated.

Question 2

Which THREE of the following are common troubleshooting steps? (Select THREE).

Accepted Answer

Identify the problem. Identifying the problem is the first step in the CompTIA A+ troubleshooting methodology. Without clearly defining symptoms and scope, subsequent steps lack direction. This step involves gathering information from users, duplicating the issue, and identifying any recent changes to the system.

Answer

Install new software

Answer

Escalate to vendor immediately

Question 3

An administrative assistant is using a spreadsheet application to create a budget report. The assistant needs to add a column that calculates the total of the previous three columns for each row. The assistant is not very experienced with formulas and is unsure how to proceed. The assistant wants to use a built-in function that will automatically sum the values. Which of the following should the assistant do to achieve this?

Accepted Answer

Use the SUM function in a formula to add the three cells.. The SUM function is the correct built-in function in spreadsheet applications (like Microsoft Excel or Google Sheets) to add a range of cells. By using a formula such as =SUM(A2:C2), the assistant can automatically calculate the total of the three columns for each row without manual errors. This directly meets the requirement to sum values efficiently.

Answer

Manually type each cell reference separated by plus signs.

Answer

Use the COUNT function to count the number of cells.

Answer

Use the AVERAGE function to find the average of the values.

Question 4

Which of the following is an example of system software?

Accepted Answer

Linux operating system. System software includes the operating system and utilities that manage hardware. Linux is an operating system, hence system software. Word processor, web browser, and spreadsheet are application software.

Answer

Spreadsheet

Answer

Web browser

Answer

Word processor

Question 5

A technician is troubleshooting a network issue and needs to view the MAC address of a device. Which notational system is the MAC address most likely represented in?

Accepted Answer

Hexadecimal. MAC addresses are typically represented in hexadecimal (base-16) format, e.g., 00:1A:2B:3C:4D:5E.

Answer

Octal

Answer

Decimal

Answer

Binary

Question 6

A network technician is troubleshooting a connectivity issue and needs to identify the destination MAC address of a frame. Which TWO of the following are true about MAC addresses? (Select TWO.)

Accepted Answer

They are 48 bits in length. MAC addresses are 48-bit (6 bytes) and commonly represented in hexadecimal. They are assigned by manufacturers and are used at the data link layer.

Answer

They are assigned by the operating system

Answer

They are represented in octal

Answer

They are used at the application layer

Question 7

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 8

A user needs to store customer information including name, address, and order history. Which database type is most appropriate?

Accepted Answer

Relational database. A relational database is the most appropriate choice because it organizes data into tables with rows and columns, allowing efficient storage and retrieval of structured customer information (name, address) while supporting relationships to order history via foreign keys. This structure enables ACID compliance and complex queries using SQL, which is ideal for transactional data with clear schema requirements.

Answer

Hierarchical database

Answer

Flat-file database

Answer

NoSQL database

Question 9

Refer to the exhibit. The user is unable to browse the internet using domain names but can access websites by IP address. Which configuration is most likely incorrect?

Accepted Answer

DNS server addresses. The user can access websites by IP address but not by domain name, which indicates that DNS resolution is failing. The DNS server addresses configuration is most likely incorrect, as the client cannot translate domain names to IP addresses without a valid DNS server. This is a classic symptom of a misconfigured or missing DNS server setting.

Answer

IPv4 address

Answer

Subnet mask

Answer

DHCP enabled

Question 10

A database administrator needs to perform CRUD operations on a table. Which TWO SQL statements are used for the 'Create' and 'Read' operations? (Select TWO.)

Accepted Answer

INSERT INTO. INSERT INTO creates new records, SELECT reads data.

Answer

DELETE

Answer

CREATE TABLE

Answer

UPDATE

Question 11

A company's IT policy mandates data backups following the 3-2-1 rule. Which TWO of the following practices align with this rule?

Accepted Answer

Having the original data on a server, a backup on a tape, and another backup on a separate cloud. The 3-2-1 backup rule requires at least three copies of data on two different media types, with one copy stored offsite. Among the options, only B and C satisfy these requirements. Option B provides three copies (server, tape, cloud) on different media (disk, tape, cloud) with cloud offsite. Option C includes the original data, a local NAS backup (disk), and a remote cloud backup (offsite), fulfilling the three copies and two media types (local disk and cloud storage). The other options fail to meet one or more requirements: A uses the same medium and location, D has only one backup, and E uses the same medium (both external drives) and same location.

Answer

Keeping one backup on the same external drive as the original

Answer

Storing one backup in a cloud storage service

Answer

Using two different external hard drives for backups, both kept in the same building

Question 12

A medium-sized business has a policy that requires all employees to use two-factor authentication (2FA) when accessing the corporate email system. The authentication method uses a time-based one-time password (TOTP) app on employees' smartphones. Several employees have reported that they cannot log in because they recently changed phones and did not transfer the TOTP seed. The help desk has been resetting 2FA for these users, but management is concerned about the security of the reset process. Which of the following procedures should the help desk follow to securely reset 2FA for a user?

Accepted Answer

Verify the user's identity through a separate out-of-band channel, then reset.. Verifying the user's identity through a separate out-of-band channel (e.g., a phone call to a known number or a text message to a previously registered device) ensures the requester is legitimate and prevents unauthorized resets. Option A is wrong because disabling 2FA reduces security and violates the company's policy. Option C is wrong because resetting 2FA upon email request alone is insecure—email can be spoofed or compromised. Option D is wrong because while in-person verification with a photo ID is secure, it is not always practical for remote employees; out-of-band verification provides a good balance of security and convenience.

Answer

Disable 2FA for the user and allow password-only access.

Answer

Reset the 2FA immediately upon user request via email.

Answer

Require the user to visit the IT department in person with a photo ID.

Question 13

You are the IT support technician for a small office with 5 computers, a shared printer, and a router providing internet access. Users report that the network has been slow and intermittent for the past two days. Additionally, print jobs from multiple users are frequently stuck or fail halfway. You have already verified that all network cables are securely connected, restarted the router and printer, and updated the printer drivers. The issue persists. One user mentions that their computer sometimes shows a 'Windows has detected an IP address conflict' notification. Based on this scenario, which course of action should you take next to resolve the most likely root cause?

Accepted Answer

Check for IP address conflicts on the network and assign static IP addresses if necessary. The IP conflict notification strongly indicates that two devices on the network have the same IP address, causing intermittent connectivity and printer issues. Option B (Disable Windows Firewall) is unrelated and could introduce security risks. Option C (Reinstall the operating system) is too drastic and unlikely to fix an IP conflict. Option D (Replace the network switch) is premature and would not resolve a conflict.

Answer

Disable Windows Firewall on all computers

Answer

Reinstall the operating system on all computers

Answer

Replace the network switch with a new one

Question 14

A server has four hard drives configured in RAID 5. One drive fails. What must the technician do to restore full redundancy?

Accepted Answer

Replace the failed drive and rebuild the array. RAID 5 uses distributed parity across all drives, allowing the array to tolerate a single drive failure without data loss. When a drive fails, the technician must replace the failed drive and then rebuild the array, during which the RAID controller reconstructs the missing data from the parity information on the remaining drives. This restores full redundancy by returning the array to a fault-tolerant state.

Answer

Replace all drives and reconfigure RAID

Answer

Simply replace the drive with a larger capacity drive

Answer

Replace the failed drive and restore from backup

Question 15

A small business is setting up a LAN. Which TWO of the following are characteristics of a LAN?

Accepted Answer

Connects devices within a single building or campus. LANs are confined to a small geographic area like a building, and typically use Ethernet or Wi-Fi. WANs cover larger areas.

Answer

Uses cellular technology like 4G LTE

Answer

Requires a modem to connect all devices

Answer

Covers a large geographic area such as a city
