CompTIA Network+ PBQs Explained (N10-009): Types, Examples & How to Prepare

Published: March 28, 2026 | 5 min read

What Are Network+ PBQs—and Why Do They Feel So Hard?

If you’ve started preparing for the CompTIA Network+ exam, you’ve probably heard this warning:

“The PBQs are where most people struggle.”

And it’s true.

Not because PBQs are impossible—but because they test something most study plans completely ignore:

👉 Your ability to actually solve real network problems.

Network+ PBQs (Performance-Based Questions) are interactive, scenario-driven questions where you don’t pick an answer—you perform a task.

You might be asked to:

Fix a broken network configuration
Analyze a topology diagram
Configure a firewall rule
Solve a subnetting problem under time pressure

There are no hints. No elimination tricks. No lucky guesses.

Either you understand what’s happening… or you don’t.

Don’t wait until exam day to see your first PBQ.

Why PBQs Are the Real Gatekeeper in Network+

Here’s what most candidates don’t realize until exam day:

PBQs aren’t just “another question type.”
They’re where CompTIA quietly separates:

People who studied
vs
People who can actually do the job

You’ll typically see 3 to 5 PBQs, and they appear right at the beginning of the exam.

That means within the first few minutes, you’re suddenly dealing with:

A multi-step troubleshooting scenario
A simulated CLI or GUI
A ticking clock

And here’s the catch:

👉 One PBQ can easily take 5–10 minutes if you’re not prepared.

That’s why so many candidates run out of time—even if they know the material.

The Moment PBQs “Click”

Most people approach PBQs the wrong way.

They try to memorize:

OSI layers
Port numbers
Definitions

But PBQs don’t ask:

“What is the OSI model?”

They ask:

“Here’s a broken network. Fix it.”

That shift—from knowledge → application—is where everything changes.

Once you start thinking like a troubleshooter instead of a student, PBQs become predictable.

How PBQs Actually Appear in the Network+ Exam

Before we dive into examples, it helps to understand the environment you’ll face.

The CompTIA Network+ gives you:

90 questions total
90 minutes
A mix of multiple-choice and PBQs
A passing score of 720/900

And right at the start—you’ll see PBQs.

You can skip them. And honestly, you probably should.

We’ll come back to that strategy later.

The 6 Types of Network+ PBQs (And What They’re Really Testing)

At first glance, PBQs seem random. But once you break them down, they fall into a few predictable patterns.

1. The “Match What You Should Already Know” PBQ

This is the classic drag-and-drop.

You’ll see something like:

Protocols
OSI layers
Network components

And you’re asked to match them correctly.

Simple? Yes.
Easy under pressure? Not always.

Because if you hesitate—even for a second—you lose time you don’t have.

2. The “Fix the Configuration” PBQ

This is where things get real.

You’re placed inside a simulated environment:

A router interface
A firewall rule set
A DHCP configuration

And something is broken.

Your job is to figure out:

What’s wrong
Where it’s wrong
How to fix it

This is where most candidates freeze—not because they don’t know the concept, but because they’ve never applied it.

3. The “Follow the Packet” PBQ

You’re given a network diagram.

Something isn’t working.

And now you need to trace:

Where the packet starts
Where it fails
Why it fails

This tests your ability to think like a network engineer:
👉 Layer by layer. Step by step.

4. The Subnetting PBQ (The Silent Killer)

This is the one people underestimate the most.

You’re given:

A network address
A requirement (e.g., 4 subnets, 50 hosts each)

And you need to calculate:

Subnets
Host ranges
Broadcast addresses

No calculator tricks. No shortcuts unless you’ve practiced.

This is where speed matters more than theory.

5. The Firewall / ACL PBQ

Here’s a scenario you’ll almost certainly see:

“Users can’t access the internet.”

You check:

IP configuration
Gateway connectivity

Everything looks fine… until you inspect the ACL.

And there it is—a single rule blocking traffic.

One line. One mistake. Entire network down.

That’s how real networks fail—and that’s exactly what PBQs simulate.

6. The Tool Output PBQ

You’re shown output from tools like:

ping
traceroute
nslookup

And asked:

👉 “What’s going on here?”

This tests interpretation, not memorization.

Real Network+ PBQ Example (How to Think Through It)

Let’s walk through a real scenario.

Scenario: VLAN Communication Failure

A user in VLAN 20 cannot reach a server in VLAN 10.

At first glance, everything looks connected.

So what do you check?

You start thinking like a troubleshooter:

Is inter-VLAN routing enabled?
Is there a Layer 3 switch or router?
Are trunk ports configured correctly?
Is the correct VLAN tagged?

Then it hits you:

👉 There’s no SVI (Switch Virtual Interface) configured for one of the VLANs.

No routing. No communication.

Problem solved.

What Changed in N10-009 (And Why PBQs Got Harder)

If you studied for older versions, you’ll notice a shift.

The new exam includes:

SD-WAN
VXLAN
Zero Trust Architecture
SASE (Secure Access Service Edge)
Infrastructure as Code (IaC)

These aren’t just buzzwords.

They represent how modern networks actually work.

And PBQs now reflect that reality.

The Biggest Mistake Candidates Make with PBQs

They try to solve them immediately.

Bad idea.

Here’s what actually happens:

You spend 8 minutes on one PBQ…
Then panic…
Then rush through the rest of the exam.

The Smart Strategy (Used by People Who Pass First Try)

Step 1: Skip PBQs at the Start

Yes—skip them.

Mark them for review.

Step 2: Finish All Multiple-Choice Questions First

This does two things:

Builds confidence
Saves time

Most candidates finish MCQs with 30–40 minutes left.

Step 3: Come Back with a Clear Head

Now you’re:

Calmer
Focused
In control

PBQs become much easier at this stage.

Step 4: Always Click “Submit”

This sounds trivial—but it’s a common failure point.

If you click “Next” without clicking “Submit”:

👉 Your work is gone.

How to Actually Practice Network+ PBQs (The Right Way)

This is where most people fail.

They:

Watch videos
Read notes
Do MCQs

And assume they’re ready.

They’re not.

PBQs require muscle memory, not just understanding.

Are Network+ PBQs Hard?

Yes.

But only if you:

Rely on memorization
Avoid hands-on practice
Don’t simulate exam conditions

If you practice properly:

👉 PBQs become predictable.

How Many PBQs Are on Network+?

CompTIA doesn’t publish an exact number.

But based on real exam data:

👉 Expect 3 to 5 PBQs

Always prepare for the upper range.

Final Thoughts: The Real Secret to Passing Network+

Here’s the truth most guides won’t tell you:

You don’t pass Network+ by knowing more.

You pass by thinking better.

Thinking like a troubleshooter
Thinking in layers
Thinking step-by-step

PBQs force you into that mindset.

And once you’re comfortable there:

👉 The exam becomes much easier than you expected.
