FC0-U71 Practice Test 10 — 10 Questions

Question 1

A product manager creates a list of user stories for a new feature. The development team estimates effort for each story and selects a set to complete in a two-week iteration. Daily standup meetings are held to discuss progress. At the end of the iteration, the team demonstrates working software to stakeholders. Which development framework is being used?

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

Accepted Answer

Scrum. The described practices — user stories, effort estimation, time-boxed two-week iterations (sprints), daily standups, and end-of-iteration demos — are the defining ceremonies of Scrum. Scrum is an Agile framework built around short, repeatable cycles that deliver working software incrementally. The explicit mention of a two-week iteration and daily standup maps directly to the Sprint and Daily Scrum events.

Question 2

A developer writes the following pseudocode: for i = 1 to 5, sum = sum + i. What does this code do?

Accepted Answer

It sums the numbers from 1 to 5. The pseudocode initializes a loop that iterates with i taking values 1, 2, 3, 4, and 5. In each iteration, the current value of i is added to the variable sum. After the loop completes, sum holds the total of 1+2+3+4+5, which is 15. This is a standard accumulator pattern used in programming to compute a running total.

Answer

It adds 5 to the sum

Answer

It multiplies numbers from 1 to 5

Answer

It prints the numbers from 1 to 5

Question 3

An administrator reviews the following access control policy:

{
  "Rule": {
    "Effect": "Deny",
    "Action": "delete",
    "Resource": "file-server",
    "Condition": {
      "IpAddress": {
        "SourceIp": "192.0.2.0/24"
      }
    }
  }
}

What does it do?

Accepted Answer

It denies delete access to the file server for requests from the 192.0.2.0/24 IP range. The policy explicitly denies delete actions for requests originating from the 192.0.2.0/24 IP range. This is achieved by using a Deny effect in the access control rule's Condition block with the SourceIp condition key. The policy does not affect other actions or IP ranges, so only delete access is denied for that specific CIDR block.

Answer

It allows delete access to the file server for all IPs

Answer

It allows read access to the file server from the IP range

Answer

It denies all actions to the file server

Question 4

A developer writes a set of instructions to sort an array of numbers in ascending order. The instructions include steps like 'compare first two numbers, swap if out of order, move to next pair, repeat until no swaps are needed.' This step-by-step procedure is known as a(n):

Accepted Answer

Algorithm. An algorithm is a finite, ordered set of steps that solves a specific problem — here, sorting an array via repeated comparisons and swaps (a bubble sort). The description explicitly gives a step-by-step procedure with a termination condition ('repeat until no swaps are needed'), which is the definition of an algorithm. It is the conceptual procedure, independent of any specific programming language.

Question 5

A database designer wants to avoid duplicate data across tables and ensure each table stores information about a single entity. Which process should the designer apply?

Accepted Answer

Normalization. Normalization is the process of organizing data in a database to reduce redundancy and dependency by dividing large tables into smaller, related tables and defining relationships between them. This ensures each table stores information about a single entity and avoids duplicate data across tables, aligning with the designer's goal.

Answer

Indexing

Answer

Transaction isolation

Answer

Backup and recovery

Question 6

A network administrator is designing a new office network. Which THREE factors should be considered when choosing between 2.4 GHz and 5 GHz Wi-Fi bands?

Accepted Answer

Speed. Option B (Speed) is correct because the 5 GHz band offers wider channels (up to 80/160 MHz) and higher throughput than the narrower 2.4 GHz channels, making data rate a key decision factor. Option C (Interference) is correct because 2.4 GHz is crowded by overlapping channels, Bluetooth, microwaves, and neighboring APs, while 5 GHz has many more non-overlapping channels and thus less interference. Option E (Range) is correct because 2.4 GHz signals penetrate walls and travel farther due to longer wavelengths, whereas 5 GHz has shorter range, so coverage requirements must guide band selection. Option A (Cellular compatibility) is not a Wi-Fi band selection factor since cellular operates on licensed spectrum independent of 2.4/5 GHz WLAN design. Option D (Number of devices) is not a direct differentiator between the bands, as client capacity depends more on AP density, channel width, and airtime than on the band itself.

Answer

Cellular compatibility

Answer

Number of devices

Question 7

A programmer is writing code that needs to repeat a block of instructions 10 times. Which programming construct is best suited for this task?

Accepted Answer

Loop. A loop is the programming construct designed to repeat a block of instructions multiple times, either a fixed number of iterations (e.g., a for loop running 10 times) or until a condition is met (e.g., a while loop). It directly matches the requirement to repeat code 10 times. This is a fundamental control-flow concept in all programming languages.

Answer

Function

Answer

Variable

Answer

Conditional (if/else)

Question 8

Which TWO of the following are recommended practices for physical security in an office environment? (Select two.)

Accepted Answer

Locking computer screens when leaving the desk. Option A is correct because locking the screen when leaving a desk prevents unauthorized individuals from accessing the system and data in the user's absence, which is a fundamental physical-access control in an office. Option D is correct because shredding documents containing sensitive information before disposal prevents dumpster-diving attacks and unauthorized recovery of confidential data, aligning with secure media disposal practices. Option B is not recommended because writing passwords on sticky notes exposes credentials to anyone who can physically see the monitor, defeating authentication controls. Option C is not recommended because sharing access badges breaks individual accountability and allows unauthorized entry under someone else's identity. Option E is not recommended because propping doors open bypasses physical access controls and enables tailgating or unauthorized entry into restricted areas.

Answer

Writing passwords on sticky notes and attaching them to monitors

Answer

Sharing access badges with colleagues

Answer

Leaving doors propped open for convenience

Question 9

A user's laptop battery no longer holds a charge and the laptop only works when plugged in. Which component should be replaced?

Accepted Answer

Battery. The battery is the component that stores electrical charge to power the laptop when unplugged. If it no longer holds a charge, the laptop will only operate when connected to the power adapter, indicating the battery has reached the end of its rechargeable life cycle and must be replaced.

Answer

RAM

Answer

Hard drive

Answer

Power adapter

Question 10

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
