CCNA Certification Practice Tests: Exam 200-301 is a companion volume to the CCNA Certification Study Guide. If you’re looking to test your knowledge before you take the CCNA exam, this book will help you by providing a combination of 1,200 questions that cover the CCNA objectives.
If you’re just starting to prepare for the CCNA exam, I highly recommend that you start with CCNA Certification Study Guide, Volume 1 and CCNA Certification Study Guide, Volume 2, both by Todd Lammle (Sybex, 2024), to help you learn about each of the objectives covered in the CCNA exam. Once you’re ready to test your knowledge, use this book to find places where you may need to study more or practice for the exam itself.
Since it is a companion to the CCNA Certification Study Guide books for Exam 200-301, this book is designed to be similar to taking the CCNA certification exam. It contains scenarios and standard multiple-choice questions similar to those you may encounter in the certification exam itself. The book contains eight chapters: six objective-centric chapters with 100 to 250 questions, weighted by the objectives, and two chapters that contain 100-question practice tests to simulate taking the exam. The bulk of the questions are in the IP Connectivity objective.
It used to be that to secure the holy grail of Cisco certifications—the Cisco Certified Internetwork Expert (CCIE)—you passed only one written test before being faced with a grueling, formidable hands-on lab. This intensely daunting, all-or-nothing approach made it nearly impossible to succeed and predictably didn’t work out too well for most people. Cisco responded to this issue by creating a series of new certifications, which not only made it easier to eventually win the highly coveted CCIE prize, but gave employers a way to accurately rate and measure the skill levels of prospective and current employees. This exciting paradigm shift in Cisco’s certification path truly opened doors that few were allowed through before!
Beginning in 1998, obtaining the Cisco Certified Network Associate (CCNA) certification was the first milestone in the Cisco certification climb, as well as the official prerequisite for each of the more advanced levels. Today, the Cisco CCNA exam remains as important in the scheme of Cisco certification as it was 20+ years ago. Of course, you can imagine that what we learned two decades ago has changed significantly, and so has the current Cisco CCNA exam. The CCNA exam is less focused on routing and switching than prior exams and more focused on a wider spectrum of technologies. The technologies include virtualization, wireless, and software-defined networking, just to name a few.
In May 2023, Cisco made an exciting and welcomed announcement about their certification offerings. The news is that the exam numbers no longer change, from exam to exam! This truly is exciting news for everyone who is in the midst of studying for a CCNA. Cisco has adopted a new policy of point releases for their exams when there is less than 20% of changes to the objectives. The current CCNA exam is now version 1.1 for the 200-301, which means that less than 20% changed since the last version of 1.0 of the 200-301. If more than 20% changes from exam to exam, then the major version will change to version 2.0, 3.0, and beyond.
The prior CCNA exam of 200-301 was retroactively assigned the version of v1.0.
The news gets even better because Cisco has published exactly what has changed from version 1.0 to version 1.1 for the 200-301 exam. In the future, when the minor or major version changes, Cisco is committed to publishing the delta objectives for each revision. The exam number will never change for these versions, so you can stay on pace for obtaining your certification.
Since the last release of the CCNA certification exam 200-301 v1.0, Cisco has retired the Cisco Certified Entry Network Technician (CCENT). You are now required to take the CCNA certification in one exam (200-301 v1.1), and there are no prerequisites and no separate parts as there were in the past CCNA exams. Cisco has introduced an entry-level exam called the Cisco Certified Support Technician (CCST) Networking Exam. The CCST exam is aimed at entry-level technicians who support and maintain Cisco equipment. The CCST has not replaced the CCENT, and rest assured, the CCNA is still the benchmark for network professionals.
For the uninitiated, the CompTIA A+ and Network+ certifications aren’t official prerequisites, but know that Cisco does expect you to have that type and level of experience before embarking on your Cisco certification journey. If you are just starting out on the journey of Cisco certification and prefer to stick with Cisco-centric material, a good starting point is the book CCNA Certification Study Guide, Volume 1: Exam 200-301 by Todd Lammle (Sybex, 2024), which includes many of the introductory topics you are expected to know by the time you start the CCNA exam process.
All of this gets us to the current day, when the climb to Cisco supremacy got much harder again. The fact that the certification process is getting harder really works better for you in the long run, because that which is harder to obtain only becomes that much more valuable when you finally do, right? Yes, indeed!
The CCNA (200-301) exam is extremely hard and covers a lot of material, so you have to really know your stuff. Taking a Cisco class or spending months with hands-on experience is definitely a requirement to succeed when faced with this monster! However, the CCNA certification is the most popular Cisco certification by far because it’s the most sought-after certification by all employers.
And once you have your CCNA, you don’t have to stop there—you can choose to continue and achieve an even higher certification, called the Cisco Certified Network Professional (CCNP). There are various certifications, and each one focuses on a specialty area. The CCNP Enterprise certification is still the most popular, with the Security certification coming in at a close second. And I’ve got to tell you that the Data Center certification is quickly catching up. Also good to know is that anyone with a CCNP specialty certification has all the skills and knowledge needed to attempt the notoriously dreaded but coveted CCIE specialty lab. But just becoming a CCNA can land you that job you’ve dreamed about, and that’s what this book is all about: helping you get and keep a great job!
Cisco, like Microsoft and other vendors that provide certification, has created the certification process to give administrators a set of skills and to equip prospective employers with a way to measure those skills or match certain criteria. And as you probably know, becoming a CCNA is certainly the initial, key step on a successful journey toward a new, highly rewarding, and sustainable networking career.
The CCNA program was created to provide a solid introduction, not only to switching and IP connectivity but also to internetworking in general, making it helpful to you in areas not exclusively Cisco’s. And regarding today’s certification process, it’s not unrealistic that network managers—even those without Cisco equipment—require Cisco certifications for their job applicants. Rest assured, if you make it through the CCNA and are still interested in Cisco and internetworking, you’re headed down a path to certain success!
This CCNA exam (200-301) tests a candidate for the knowledge and skills required to successfully install, operate, and troubleshoot a small branch office network to a medium-sized enterprise network. The exam includes questions on the operation of IP data networks, LAN switching technologies, IPv6, IP routing technologies, IP services, network device security, and basic troubleshooting. The exam also includes questions on physical and network security, network troubleshooting, and WAN technologies. We also see wireless technology added as an objective, since many networks today consist of wired and wireless technologies.
This CCNA exam has also added an objective domain to consider the expanse of virtualized networking. Both private and public cloud-based networks are included in this objective domain. The CCNA exam added the objective domain of automation and programmability to accommodate this real-world requirement. Much of what we do today must scale and be reproducible with expected results.
All you have to do is pass the CCNA exam (200-301). Oh, but don’t you wish it were that easy? True, it’s just one test, but it’s a whopper, and to pass it you must possess enough knowledge to understand what the test writers are saying, and you need to know everything I mentioned previously! Hey, it’s hard, but it can be done!
You may take the CCNA or any Cisco exam at any of the Pearson VUE authorized testing centers. For information, check www.pearsonvue.com or call 877-404-EXAM (3926).
To register for a Cisco exam, follow these steps:
Determine the number of the exam you want to take. (The CCNA exam is 200-301 v1.1.)
Register with the nearest Pearson VUE testing center. At this point, you will be asked to pay for the exam in advance. As of this writing, the CCNA exam is $300. The exams must be taken within one year of payment. You can schedule exams up to six weeks in advance or as late as the day you want to take it—but if you fail a Cisco exam, you must wait five days before you will be allowed to retake it. If something comes up and you need to cancel or reschedule your exam appointment, contact Pearson VUE at least 24 hours in advance.
When you schedule the exam, you’ll get instructions regarding all appointment and cancellation procedures, the ID requirements, and information about the testing-center location.
Pearson VUE has recently introduced OnVUE online proctored exams. Currently on their registration page they urge you to schedule an OnVUE online proctored exam that can be taken from the comfort of your home.
The Cisco exams contain about 50–60 questions and must be completed in about 120 minutes or less. This information can change per exam. You must get a score of about 85 percent to pass this exam, but again, each exam can be different.
Many questions on the exam have answer choices that at first glance look identical, especially the syntax questions! So remember to read through the choices carefully because close just doesn’t cut it. If you get commands in the wrong order or forget one measly character, you’ll get the question wrong. So, practice; do the hands-on exercises found at the end of each chapter in the books CCNA Certification Study Guide, Volume 1, and CCNA Certification Study Guide, Volume 2 by Todd Lammle (Sybex, 2024), and perform them over and over again until they feel natural to you.
Also, never forget that the right answer is the Cisco answer. In many cases, more than one appropriate answer is presented, but the correct answer is the one that Cisco recommends. On the exam, you will always be told to pick one, two, or three options, never “choose all that apply.” The Cisco exam may include the following test formats:
Multiple-choice single answer
Multiple-choice multiple answers
Drag-and-drop
Router simulations
Cisco proctored exams will not show the steps to follow in completing a router interface configuration, but they do allow partial command responses. For example, show run, sho running, or sh running-config would be acceptable.
Here are some general tips for exam success:
Arrive early at the exam center so you can relax and review your study materials.
Read the questions carefully. Don’t jump to conclusions. Make sure you’re clear about exactly what each question asks. “Read twice, answer once,” is what I always tell my students.
When answering multiple-choice questions that you’re not sure about, use the process of elimination to get rid of the obviously incorrect answers first. Doing this greatly improves your odds if you need to make an educated guess.
You can no longer move forward and backward through the Cisco exams, so double-check your answer before clicking Next since you can’t change your mind.
After you complete an exam, you’ll get immediate, online notification of your pass or fail status, a printed examination score report that indicates your pass or fail status, and your exam results by section. (The test administrator will give you the printed score report.) Test scores are automatically forwarded to Cisco within five working days after you take the test, so you don’t need to send your score to them. If you pass the exam, you’ll receive confirmation from Cisco, typically within two to four weeks, sometimes a bit longer.
This book includes over 1,000 practice test questions, which will help you get ready to pass the CCNA exam. The interactive online learning environment that accompanies CCNA Certification Practice Tests: Exam 200-301, Second Edition provides a robust test bank to help you prepare for the certification exams and increase your chances of passing them the first time! By using this test bank, you can identify weak areas up front and then develop a solid studying strategy using each of these testing features.
The test bank also offers two practice exams. Take these practice exams just as if you were taking the actual exam (without any reference material). When you’ve finished the first exam, move on to the next one to solidify your test-taking skills. If you get more than 90 percent of the answers correct, you’re ready to take the certification exams.
You can access the Sybex interactive online test bank at www.wiley.com/go/sybextestprep.
Like all exams, the CCNA certification from Cisco is updated periodically and may eventually be retired or replaced.

Studying to take a Cisco exam takes time, lots of time! Understandably, we can find ourselves in the middle of studying for one exam, such as the prior CCNA (200-301 v1.0) exam, only to find out it is being retired and replaced with the CCNA (200-301 v1.1). To maintain your momentum, you will find yourself frantically looking at what exactly changed from the past exam to the current exam. For this purpose, I have included the delta exam objectives in this book. These delta objectives are the new or changed objectives that were not present on the prior exam or were not emphasized in the prior exam. This section is only a guide for you to prepare for the transition to the current certification of CCNA (200-301 v1.1). This section is not the only portion you must study in addition to the prior study material.
Exam objectives are subject to change at any time without prior notice and at Cisco’s sole discretion. Please visit Cisco’s certification website (www.cisco.com/c/en/us/training-events.html) for the latest information on the CCNA (200-301 v1.1) exam. Table 7 covers the differences between the prior CCNA (200-301 v1.0) exam and the new CCNA (200-301 v1.1) exam objectives.

This book is composed of eight chapters. Each of the first six chapters covers a domain, with a variety of questions that can help test your real-world, scenario, and best practices networking knowledge. The final two chapters are complete practice exams that can serve as timed practice tests to help determine if you’re ready for the CCNA exam.
I recommend taking the first practice exam to help identify where you may need to spend more study time and then using the domain-specific chapters to test where your domain knowledge is weak. Once you’re ready, take the second practice exam to make sure you’ve covered all the material and are ready to attempt the CCNA exam.
The book is separated into eight chapters, six chapters to reflect the major objectives and two chapters with practice tests:
Chapter 1

The interface is operating normally.
The cable is disconnected for the node.
A router is connected to the switch via a Fast Ethernet interface. Intermittently you experience an outage. What should be done first to remedy the problem? Refer to the following figure.
The speed and duplex should be set statically.
Change the VLAN to a less crowded VLAN.
Change the switchport mode to a trunk.
Set the switchport to auto-negotiate.
In the following figure, what can you conclude about the interface or node?
There are no problems with the interface.
The interface is auto-negotiating speed and duplex.
There are a large number of broadcasts.
The node needs a faster network interface.
You have statically set an interface to 100 Mb/s full-duplex. However, the device you are plugging in will not work. Which command(s) would you use to set speed and duplex back to auto-negotiate?
speed auto
duplex auto
speed autonegotiate
duplex autonegotiate
switchport autonegotiate
interface autonegotiate
You have auto-negotiation turned off on the node, but it is turned on at the switch’s interface connecting the node. The interface is a 10/100/1000 Mb/s interface and the node is 100 Mb/s full-duplex. What will the outcome be when you plug in the node?
The switch interface will be set to the 100 Mb/s full-duplex.
The switch interface will be set to the 100 Mb/s half-duplex.
The switch interface will be set to the 10 Mb/s full-duplex.
The switch interface will be set to the 10 Mb/s half-duplex.
You plug a 100 Mb/s hub into a switch. What is the expected outcome?
The switch interface will be set to the 100 Mb/s full-duplex.
The switch interface will be set to the 100 Mb/s half-duplex.
The switch interface will be set to the 10 Mb/s full-duplex.
The switch interface will be set to the 10 Mb/s half-duplex.
You want to see the status of all speed and duplex negotiations for all interfaces. Which command would you use?
show run
show interfaces counters

TCP
UDP
NMS
Which is a correct statement about the Transmission Control Protocol (TCP)?
TCP is a connectionless protocol.
TCP allows for error correction.
TCP is faster than UDP.
TCP allows for retransmission of lost segments.
Which statement correctly describes what happens when a web browser initiates a request to a web server?
The sender allocates a port dynamically above 1024 and associates it with the request.
The receiver allocates a port dynamically above 1024 and associates it with the request.
The sender allocates a port dynamically below 1024 and associates it with the request.
The receiver allocates a port dynamically below 1024 and associates it with the request.
Which protocol and port number is associated with SMTP?
UDP/69
UDP/68
UDP/53
TCP/25
How does TCP guarantee delivery of segments to the receiver?
Via the destination port
TCP checksums
Window size
Sequence and acknowledgment numbers
When a programmer decides to use UDP as a transport protocol, what is a decision factor?
Redundancy of acknowledgment is not needed.
Guaranteed delivery of segments is required.
Windowing flow control is required.
A virtual circuit is required.
Which mechanism allows for programs running on a server (daemons) to listen for requests through the process called binding?
Headers
Port numbers
MAC address
Checksums
Which is a correct statement about sliding windows used with TCP?
The window size is established during the three-way handshake.
Sliding windows allow for data of different lengths to be padded.
It allows TCP to indicate which upper-layer protocol created the request.
It allows the router to see the segment as urgent data.
Why does DNS use UDP for queries?
DNS requires acknowledgment of the request for auditing.
The requests require flow control of UDP.
DNS requests are usually small and do not require connections setup.
DNS requires a temporary virtual circuit.
What is required before TCP can begin sending segments?
Three-way handshake
Port agreement
Sequencing of segments
Acknowledgment of segments
