FC0-U71 Practice Test 6 — 10 Questions

Question 1

A company has a server that hosts a critical database. The server uses RAID 5 with three disks. One disk fails. What is the immediate impact on data availability?

Accepted Answer

Data is still available, but performance may degrade. RAID 5 uses block-level striping with distributed parity. With three disks, the array can tolerate a single disk failure without data loss because the parity information on the remaining two disks can reconstruct the missing data on the fly. Therefore, data remains fully available immediately after one disk fails, though read and write performance may degrade due to the overhead of parity calculation and reconstruction.

Answer

Data is available only after replacing the disk

Answer

The server will shut down

Answer

All data on the array is lost

Question 2

Which of the following is a valid SQL statement to retrieve all records from a table named 'Employees'?

Accepted Answer

SELECT * FROM Employees. SELECT * FROM Employees is the correct SQL syntax to retrieve all columns and rows from the table. The other options have incorrect syntax or keywords.

Answer

GET * FROM Employees

Answer

FETCH * FROM Employees

Answer

READ * FROM Employees

Question 3

What is the binary representation of the decimal number 10?

Accepted Answer

1010. The decimal number 10 is converted to binary by dividing by 2 repeatedly: 10 ÷ 2 = 5 remainder 0, 5 ÷ 2 = 2 remainder 1, 2 ÷ 2 = 1 remainder 0, 1 ÷ 2 = 0 remainder 1. Reading the remainders from bottom to top gives 1010. This matches option C.

Answer

1001

Answer

1110

Answer

1100

Question 4

Which TWO of the following are types of optical disc storage? (Select exactly two.)

Accepted Answer

DVD. DVD (Digital Versatile Disc) is a type of optical disc storage that uses a laser to read and write data on a reflective plastic disc. It is a standard optical media format, distinct from magnetic or solid-state storage technologies.

Answer

SSD

Answer

HDD

Answer

Flash drive

Question 5

A company wants to implement a backup solution that allows for quick restoration of individual files. Which backup type should be used?

Accepted Answer

Full backup. A full backup creates a complete copy of all selected data, allowing any individual file to be restored directly from that single backup set without needing to process other backup sets. This makes it the simplest and fastest option for restoring specific files, as no additional dependencies or chain reconstructions are required.

Answer

System image backup

Answer

Differential backup

Answer

Incremental backup

Question 6

What is the difference between a threat and a vulnerability?

Accepted Answer

A threat is a potential harm, and a vulnerability is a weakness. A threat is a potential source of harm (e.g., a hacker), while a vulnerability is a weakness that can be exploited (e.g., unpatched software).

Answer

They are the same thing

Answer

A threat is a weakness, and a vulnerability is a danger

Answer

A threat is a type of malware, and a vulnerability is a type of attack

Question 7

A security analyst is evaluating risks to the company's network. According to the risk formula (Risk = Likelihood × Impact), which THREE of the following are considered vulnerabilities?

Accepted Answer

Weak encryption used for data in transit. A vulnerability is a weakness that can be exploited by a threat.

Answer

A hacker attempting to guess passwords

Answer

A fire in the data center

Question 8

An employee allows a delivery person to enter a secure office building by holding the door open. The delivery person does not have an access badge. Which social engineering attack is this?

Accepted Answer

Tailgating. Tailgating (or piggybacking) occurs when an unauthorized person follows an authorized person into a restricted area without proper authentication.

Answer

Phishing

Answer

Baiting

Answer

Pretexting

Question 9

What is the primary risk of using public Wi-Fi without a VPN?

Accepted Answer

Data transmitted can be intercepted by attackers. Public Wi-Fi is often unencrypted, allowing attackers to intercept data transmitted over the network. A VPN encrypts traffic, protecting data in transit.

Answer

The Wi-Fi network may be slower

Answer

The device may overheat

Answer

Increased risk of malware infection from the network

Question 10

A user is concerned about connecting to a public Wi-Fi network at a coffee shop. Which security measure can best protect their data?

Accepted Answer

Use a VPN. A VPN encrypts traffic between the user's device and the VPN server, protecting data on public networks.

Answer

Use HTTPS websites only

Answer

Use a firewall

Answer

Disable antivirus
