CompTIA Network plus N10-007 free practice test exam questions

CompTIA Network+ free practice test for Exam N10-007

This is a five-question example (one per Network+ N10-007 main exam objective) of the level of testing at the CompTIA Network+ exam. This practice test consists exclusively of multiple-choice questions while our CertBlaster Exam Simulator does include the performance-based questions as well. This example aims at demonstrating the level of complexity you can expect at the actual exam.


The sample questions below are all multiple choice. To access interactive questions as well as grading, reports, and your custom “Personal Testing Plan”, you will need the CertBlaster Exam Simulation software.

Question 1

At which layer of the OSI model is a PDU referred to as a frame?

Data Link


A PDU begins its evolution at the Physical layer (Layer 1) where it is a series of bits. At the Data Link layer (Layer 2), it becomes a frame. At the Network layer (Layer 3), it becomes a packet. At the Transport layer (Layer 4), it is a segment and is passed to the upper layers. It is important to be able to correlate the terms and layers when discussing PDUs. For example, when the term “deep packet analysis” is used, you should know that you are talking about a device operating at the Network layer (Layer 3). So, the correct choice is Data Link.

CompTIA Network+ N10-007 exam objectives addressed by question 1

Main exam objective: 1.0 Networking Concepts

Exam sub-objective: 1.5 Compare and contrast the characteristics of network topologies, types and technologies.

Question 2

A SAN 10+ Gb Ethernet creates overhead on both the CPU and OS. Which of the choices provides the highest efficiency along with low overhead and latency?

Fibre Channel


While Ethernet-based standards and protocols are extremely fast, the InfiniBand protocols reduce the workload on server OSs and hardware. This results in faster data transfers with considerably lower latencies. The correct choice is therefore InfiniBand.

CompTIA Network+ N10-007 exam objectives addressed by question 2

Main exam objective: 2.0 Infrastructure

Exam sub-objective: 2.4 Explain the purposes of virtualization and network storage technologies.

Question 3

The acronym MTTR is used in your documentation. How would you prepare to reduce this factor?

Predict the occurrence
Use MTBF and have replacements on hand
Create a solid response policy
Reduce the stresses on the components


MTTR is the Mean Time To Repair. This indicates a failure with a calculated replacement timeline. The best way to reduce this time is to have the parts on hand. If you know that a server drive running 24/7 will fail within a specified timeframe, have one on hand. Having said this, the chances are high that you will upgrade most devices before they fail. The correct choice is therefore “Use MTBF and have replacements on hand”.

CompTIA Network+ N10-007 exam objectives addressed by question 3

Main exam objective: 3.0 Network Operations

Exam sub-objective: 3.2 Compare and contrast business continuity and disaster recovery concepts.

Question 4

There are rumors of widespread layoffs in a company. A programmer that feels at risk modifies his programming to execute malicious device encryption code if he is unemployed at the end of the month. The infected device(s) will display instructions requiring payment to regain control of the device(s). How would you categorize this action? (Choose two)

Logic bomb
Trojan horse
Back door



Logic bombs are classic demonstrations of time-dependent malware. The code that executes encrypts the device and demands payment, classifying it as ransomware. The correct choices are Logic bomb and Ransomware .

CompTIA Network+ N10-007 exam objectives addressed by question 4

Main exam objective: 4.0 Network Security

Exam sub-objective: 4.4 Summarize common networking attacks.

Question 5

You have concluded that two hosts have duplicate IP addresses on your network. How could this happen?

They are using static IP addresses
They are using the wrong gateway
DHCP leases are too long
None of these


In this case, you would check the IP addresses and make sure they are not statically assigned. If one host must use a static address, reserve it in the DHCP scope and assign the second host to use DHCP. The correct choice is “They are using static IP addresses”.

CompTIA Network+ N10-007 exam objectives addressed by question 5
