FC0-U61 Practice Test 18 — 15 Questions

Question 1

Based on the exhibit, what actions are permitted by this policy?

Accepted Answer

GetObject only. The policy has an Allow statement for s3:GetObject (read) and a Deny statement for s3:DeleteObject. Deny overrides Allow. No other actions are mentioned, so only GetObject is allowed. ListObjects is not explicitly allowed. PutObject is not mentioned.

Answer

GetObject and ListObjects

Answer

GetObject and DeleteObject

Answer

PutObject and GetObject

Question 2

Which of the following best describes the difference between a compiler and an interpreter?

Accepted Answer

A compiler translates the entire source code into machine code before execution; an interpreter executes code line by line.. A compiler translates source code into machine code all at once, producing an executable. An interpreter executes code line by line. Both check syntax but at different times. Compilers usually generate faster programs.

Answer

Compiled programs run slower than interpreted programs.

Answer

A compiler executes code line by line; an interpreter translates the entire program at once.

Answer

A compiler checks for syntax errors at runtime; an interpreter checks at compile time.

Question 3

A developer is testing a piece of code that calculates discounts. The code should give 10% off for orders over $100, and 5% off for orders between $50 and $100. Which test input set would best verify boundary conditions?

Accepted Answer

$49.99, $50.00, $99.99, $100.00, $100.01. Boundary testing requires values at, just below, and just above each boundary. Option A covers all boundaries ($49.99, $50.00, $99.99, $100.00, $100.01). Others miss some boundaries or are not precise.

Answer

$50, $100, $150

Answer

$0, $50, $100, $200

Answer

$50.00, $100.00

Question 4

A program needs to display a message based on a user's age. If age is 18 or over, it displays 'Adult'; otherwise, it displays 'Minor'. Which control structure should be used?

Accepted Answer

If-else statement. An if-else statement is used to choose between two code paths based on a condition. A for loop is for iteration. A while loop repeats until a condition is false. A switch-case tests multiple discrete values.

Answer

For loop

Answer

Switch-case statement

Answer

While loop

Question 5

A programmer writes a script that automates the backup of files every night. Which type of programming paradigm is this script likely using?

Accepted Answer

Procedural programming. A simple backup script is typically a linear sequence of steps, characteristic of procedural programming. Object-oriented would involve classes and objects; event-driven waits for events; functional uses pure functions and immutability.

Answer

Event-driven programming

Answer

Object-oriented programming

Answer

Functional programming

Question 6

Which THREE of the following are phases in the software development lifecycle (SDLC)?

Accepted Answer

Design. Requirements gathering, design, and testing are standard SDLC phases. Compilation is a technical step, not a phase. Deployment is also a phase, but only three are correct? Actually deployment is a phase, but our options: Requirements, Design, Compilation, Testing, Deployment. So three are Requirements, Design, Testing. Compilation is not a phase, and Deployment is also a phase but we need exactly three; typical core phases are Requirements, Design, Implementation, Testing, Deployment, Maintenance. So we choose Requirements, Design, Testing. Implementation would also be valid but not in options. So three correct: A, B, D.

Answer

Deployment

Answer

Compilation

Question 7

A developer is debugging a program that is producing incorrect output. Which of the following are common debugging techniques? (Choose three.)

Accepted Answer

Using a debugger. Common debugging techniques include adding print statements, using a debugger, and performing code reviews. Changing requirements or reinstalling the OS are not debugging techniques.

Answer

Reinstalling the operating system

Answer

Changing the program requirements

Question 8

Based on the exhibit, what will be the last value output?

Accepted Answer

5. The loop runs while count <= 5. It outputs 1,2,3,4,5. The last output is 5. Then count becomes 6 and loop exits. 1 is first, 6 is not output because loop ends.

Answer

6

Answer

10

Answer

1

Question 9

A software developer is using an integrated development environment (IDE) to write a Python script that processes a CSV file containing customer data. The script uses a for loop to iterate over rows and calculates a total purchase amount. When the developer runs the script, it throws an error: "IndexError: list index out of range". The developer suspects the error occurs when the script tries to access a column that doesn't exist in some rows. Which debugging strategy should the developer use first to isolate the issue?

Accepted Answer

Place a breakpoint inside the loop and step through each row in debug mode.. Using a debugger to step through the loop allows inspection of each row and identification of which row causes the error. Adding a try-except block masks the problem. Checking the file beforehand might not reveal the exact runtime issue. Rewriting the script changes the approach without addressing the root cause.

Answer

Rewrite the script to use a dictionary instead of a list.

Answer

Add a try-except block to catch the exception and continue processing.

Answer

Examine the CSV file to ensure all rows have the same number of columns.

Question 10

A junior developer is creating a script to generate reports for each of 10 departments. The script should run the report generation code exactly 10 times. Which control structure should be used?

Accepted Answer

for loop. A for loop is the best choice for iterating a fixed number of times. A while loop could work but is less clear for definite iteration. if-else and switch are conditional structures, not iterative.

Answer

while loop

Answer

if-else

Answer

switch

Question 11

A team is using version control for a software project. A developer accidentally committed a buggy change to the main branch. Which action should the team take to fix this while preserving the commit history?

Accepted Answer

Use the revert command to create a new commit that undoes the changes.. Revert creates a new commit that undoes the changes, maintaining history. Deleting the repository or forcing a history rewrite are risky and not standard practice. Manual undo by all developers is inefficient and error-prone.

Answer

Ask all developers to manually undo the changes in their local copies.

Answer

Delete the repository and start over.

Answer

Force delete the commit from history.

Question 12

A team of developers is collaborating on a mobile app using Git. One developer, Alice, is working on a new feature in a branch called "new-feature". Bob, another developer, has pushed several bug fixes to the main branch. Alice now wants to incorporate Bob's bug fixes into her feature branch. Which sequence of Git commands should Alice use to achieve this with minimal disruption?

Accepted Answer

git checkout new-feature, git merge main, then resolve conflicts if any.. Merging the main branch into the feature branch (git checkout new-feature, git merge main) brings the fixes into Alice's branch. The opposite (merging feature into main) would add unfinished work to main. Rebasing with force push is dangerous. Creating a new branch doesn't bring in fixes.

Answer

git fetch, git rebase new-feature onto origin/main, then force push.

Answer

git checkout -b new-feature, git push.

Answer

git checkout main, git pull, git merge new-feature, then push.

Question 13

A developer is designing a website and needs to choose a client-side scripting language. Which of the following are scripting languages? (Choose two.)

Accepted Answer

JavaScript. JavaScript and Python are scripting languages. Java and C++ are compiled languages; HTML is a markup language.

Answer

Java

Answer

HTML

Answer

C++

Question 14

After a ransomware attack, which step should be taken FIRST in the incident response process?

Accepted Answer

Disconnect affected systems from network. The first step in incident response after a ransomware attack is to contain the threat by disconnecting affected systems from the network. This prevents the ransomware from encrypting additional files on other systems and stops lateral movement, which is critical because ransomware often uses network shares and SMB protocols to spread. Immediate isolation preserves forensic evidence and limits the scope of the incident before any other actions are taken.

Answer

Notify law enforcement

Answer

Restore from backup

Answer

Pay the ransom

Question 15

Drag and drop the steps to install a printer on Windows 10 via USB into the correct order.
