FC0-U71 Practice Test 40 — 15 Questions

Question 1

A small business uses a legacy desktop application for inventory management. The application was designed for Windows 7 and has not been updated. The company recently upgraded its workstations to Windows 10. Now, when employees try to run the inventory application, it either crashes immediately or displays errors about missing components. The company relies on this application daily and cannot afford downtime. The IT administrator has tried running the application in compatibility mode for Windows 7, but the crashes persist. There is no alternative application available, and the vendor is out of business. Which of the following is the BEST course of action to allow the business to continue using this application?

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

Accepted Answer

Set up a virtual machine running Windows 7 and install the application there.. Using a virtual machine with Windows 7 provides a full compatible environment, allowing the legacy application to run as before. Option A is wrong because the vendor is out of business, so contacting them is futile. Option B is wrong because hiring a developer to rewrite the application is costly, time-consuming, and not a quick fix. Option D is wrong because reinstalling the application on Windows 10 will likely result in the same crashes and errors due to incompatibility.

Answer

Contact the vendor for an updated version of the software.

Answer

Hire a developer to rewrite the application for Windows 10.

Answer

Uninstall the application and reinstall it using the original installation media.

Question 4

A user reports that their computer is unable to access the internet, but can access local network resources. Which of the following is the most likely cause?

Accepted Answer

Incorrect default gateway. The default gateway is the router that connects a local subnet to other networks, including the internet. If the default gateway is incorrect, the computer can communicate within its own subnet (local resources) but cannot route packets to external networks, causing internet access to fail while local access remains functional.

Answer

Windows Firewall blocking outbound traffic

Answer

DNS server not responding

Answer

Faulty Ethernet cable

Question 5

A company wants to protect against data loss if a single hard drive fails. They have three identical drives. Which RAID configuration provides fault tolerance while maximizing storage capacity?

Accepted Answer

RAID 5. RAID 5 uses block-level striping with distributed parity, so if one of the three drives fails, the data can be rebuilt from the remaining drives plus the parity information. With three drives, RAID 5 provides fault tolerance for a single drive failure while using only one drive's worth of capacity for parity, maximizing usable storage (2/3 of total raw capacity).

Answer

RAID 0

Answer

JBOD

Answer

RAID 1

Question 6

Which THREE of the following are advantages of using a cloud database service (DBaaS) over an on-premises database? (Select THREE.)

Accepted Answer

No need to manage physical hardware. DBaaS provides managed services, automatic scaling, and no hardware management, reducing operational overhead.

Answer

Lower latency than on-premises in all cases

Answer

Full control over the operating system

Question 7

A company stores customer data in a flat file. Which of the following is a disadvantage of using a flat file compared to a relational database?

Accepted Answer

Flat files do not support concurrent multi-user access. Flat files lack built-in support for concurrent access, leading to data corruption or conflicts when multiple users try to update the file simultaneously.

Answer

Flat files are slower for sequential reads

Answer

Flat files support complex queries

Answer

Flat files enforce referential integrity

Question 8

A company needs to store customer orders with items and quantities. The database currently has a table 'Customers' and a table 'Products'. Which of the following is the best way to represent the many-to-many relationship between orders and products?

Accepted Answer

Create an Order_Items table with foreign keys to Orders and Products, plus a Quantity column.. It creates a junction table (Order_Items) that resolves the many-to-many relationship between Orders and Products. The Order_Items table includes foreign keys referencing both the Orders and Products tables, plus a Quantity column to store the number of each product in an order, which is the standard normalized relational database design.

Answer

Create a single table containing all customer, order, and product information.

Answer

Store a JSON list of product IDs in an OrderProducts column in the Orders table.

Answer

Add columns Product1, Product2, Product3 to the Orders table.

Question 9

A company uses a relational database with a 'Customers' table and an 'Orders' table. Each order must be linked to exactly one customer. Which type of relationship exists between Customers and Orders?

Accepted Answer

One-to-many. One customer can have many orders, but each order belongs to one customer, which is a one-to-many relationship.

Answer

No relationship

Answer

Many-to-many

Answer

One-to-one

Question 10

An IT specialist is explaining ASCII and Unicode to a trainee. Which statement accurately describes a difference between ASCII and Unicode?

Answer

ASCII uses 8 bits per character and supports 256 characters.

Answer

Unicode uses 16 bits per character, while ASCII uses 7 bits.

Answer

ASCII is a variable-width encoding, while Unicode uses a fixed width.

Question 11

Which TWO of the following are features of productivity software?

Accepted Answer

Spell check. Spell check is a core feature of productivity software such as word processors and office suites. It automatically compares words against a built-in dictionary to identify and suggest corrections for misspellings, enhancing document accuracy and user efficiency.

Answer

Disk defragmentation

Answer

Network firewall

Answer

Virus scanning

Question 12

A user reports that their computer is unable to connect to the internet, but other devices on the same network work fine. Which of the following is the MOST likely cause?

Accepted Answer

Faulty network cable. A faulty network cable can prevent a single computer from connecting to the internet while other devices on the same network work fine. This is because the cable physically connects the computer to the network switch or router, and if it is damaged, the link may fail entirely or cause excessive packet loss, isolating only that device.

Answer

Router firewall blocking traffic

Answer

DHCP server failure

Answer

DNS server misconfiguration

Question 13

During a code review, a team notices that a function modifies a global variable instead of returning a value. Which software development principle is being violated?

Accepted Answer

Modularity. Modularity is the principle that a function should perform a single, well-defined task and communicate with the rest of the program through its inputs and outputs, not by altering shared state. By modifying a global variable instead of returning a value, the function creates hidden dependencies and side effects, which breaks the modular design that keeps components independent and testable.

Answer

Encapsulation

Answer

Polymorphism

Answer

Inheritance

Question 14

A network administrator wants to automatically assign IP addresses to all devices on the network. Which service should be configured on the server?

Accepted Answer

DHCP. Dynamic Host Configuration Protocol (DHCP) is the correct service because it automatically assigns IP addresses, subnet masks, default gateways, and other network configuration parameters to devices on a network. This eliminates the need for manual static IP configuration and ensures each device receives a unique IP address from a defined pool, preventing address conflicts.

Answer

DNS

Answer

HTTP

Answer

NAT

Question 15

A project team is using Git for version control. Which TWO actions are typical Git operations? (Choose TWO.)

Accepted Answer

Branch. Branch allows developers to create separate lines of development, and Commit saves changes to the local repository. Both are core Git operations. While Push is also valid, the question asks for two typical operations; Branch and Commit are fundamental. Increase and Compile are not Git commands.

Answer

Compile

Answer

Increase

Answer

Push
