CREST Certified Tester – Infrastructure (CCT INF) – Notes for Candidates

The notes for candidates gathers essential information about the CCT INF exam and intends to support CREST candidates on their preparation increasing their chances of success. It is split into 4 sections:

1. Exam Overview: explains the CCT INF exam and its general scope

2. Exam Structure: information on format, duration, materials allowed

3. Exam Content: details the content structure of the exam and what to expect

4. Exam Grading: information on marking structure and pass mark

1. Exam overview

The CCT INF is an advanced level examination that tests a candidate’s knowledge and expertise in assessing operating systems, common network services and general network infrastructure security as well as Linux, cloud, databases and other web technologies. The CCT INF examination also covers a common set of core skills and knowledge, and is exclusively available in over 1,000 Pearson VUE Test Centres globally. 

2. Exam structure

Exam format

The CCT INF exam has two distinct parts:

– A written exam which is made of two components: a multiple-choice test and a written scenario

– A practical exam

The multiple–choice component tests a candidates’ knowledge of the subject areas and the scenario assesses a candidates’ risk analysis and report writing skills.

The multiple–choice component tests a candidates’ knowledge of the subject areas and the scenario assesses a candidates’ risk analysis and report writing skills.

The practical component tests candidates’ hands-on penetration testing methodology and skills against reference networks, hosts and applications. Candidates will not be able to use their own laptops. A version of Kali Linux will be available within the practical exam environment to address the practical assessment. A version of Windows Server 2022 is being tested and will be introduced later in 2024 to further support candidates.

Your lab is a unique instance and is built and verified before being displayed to you. All answers are marked automatically.

Candidates can now take the written and practical exams in whichever order they prefer.

Exam duration

Written exam

The written exam duration is 3 hours in total, split as follows:

– Multiple-choice test (1 hour)

– Written scenario (2 hours)

Candidates will be given an additional 15 minutes for reading time prior to the start of written scenario component.

Candidates must start with the multiple-choice test followed by the written scenario component. The questions can be answered in any order within each component.

Practical exam

The practical exam duration is 3 hours and candidates will be given an additional 20 minutes for reading time prior to the start of the exam.

Pre-requisites

There are no pre-requisites to the CCT INF exam.

Exam notes

Written exam

The written exam is closed book. Therefore, no books, written notes, internet access or other electronic devices will be allowed. This applies to both components of the written exam: the multiple-choice test and the written scenario. 

Note: the written scenario component does not include a practical element as it did in previous iterations. 

Practical exam

Candidates are able to pre-upload files ahead of their practical exam via CRESTDrive. These files will be accessible on the day of the exam. 

3. Exam content

The CCT INF syllabus has been revised and updated to include and expand on relevant areas and skills. Areas such as macOS security, Windows desktop lockdown, and social engineering are now part of the exam. There is also more focus on cloud services and security where six new skills have been introduced. Network intrusion protection, Unix exploitation and NoSQL injection are also amongst the areas with new skills. The new exam also builds on the existing soft skills and assessment management section introducing global and regional law and compliance components and report quality assurance.  

4. Exam grading

Written exam (180 marks)

– Multiple choice test (60 marks)

– Written scenario (120 marks)

Practical exam (180 marks)

– Four 30-mark sections

– One 60-mark section

Pass mark

Written exam

Candidates must achieve at least two thirds or 66% in each component (multiple choice test and written scenario) to achieve a pass. Passing one of the sections but failing the other one will result in a failure overall. 

Practical exam

Candidates must achieve at least two thirds or 66% in the practical exam to achieve a pass.

Feedback

Written exam

Candidates will receive their multiple-choice test results at the end of the exam with a breakdown of the areas and how they have performed.

The results for the written scenario component and overall result of their written exam will be provided within 20 days from when the exam has been taken.

Practical exam

Candidates will receive an email from Pearson VUE once exam results are available in their Pearson VUE account. Results will usually be available within 24 hours but might take up to 48 hours in some cases due to additional verification checks. Candidates will receive their score in each section. 

If you have not received your results after 48 hours and/or if you have any queries, please contact us via [email protected].

Sample questions

Examples of questions that help candidates to understand what to expect from the examination environment. You will find our sample questions here.

Sample scenario

Please visit the ‘Sample scenario’ drop-down section below.

Practical exam

In order to allow candidates to familiarise themselves with the tooling available in the exam environment, a virtual machine is available. The virtual machine hosts a version of Kali Linux, which is the machine available to use during the CCT INF Practical exam. 

This virtual machine is an exact copy of the one that candidates will use in the CCT INF Practical exam. This machine have a large number of tools installed, including versions of Nessus and BurpSuite.  

The Amazon Machine Image (AMI) provided below is an exact copy of the exam machine, but BurpSuite and Nessus do not have licenses. These are fully licensed in the exam environment at Pearson VUE. 

Note: a version of the Windows Server 2022 machine is being tested and will be introduced in August 2024.

The written scenario component is part of the written CCT INF exam which also includes a multiple-choice test.

The scenario essentially assesses the candidate’s knowledge and ability to write reports. There are also elements related to scoping engagements, assessing risks inherent to their findings and composing an issues’ write up for a report. Candidates could also be expected to demonstrate an understanding of relevant legislation affecting penetration testing in their operating jurisdiction.

Format

The written component starts after candidates have submitted their answers to the multiple-choice component within their written exam. They will be given 15 minutes before the scenario examination starts to read through the requirements and no examination activities are permitted during this time.

Once the written scenario starts, candidates will need to answer long form questions and will be given 120 minutes to do so. There is no requirement to complete each question in the order that they are presented meaning that candidates are free to complete them as they wish, provided that they do so within the allotted time.

Reminder: candidates must achieve the minimum pass mark in both the multiple-choice and written scenario parts to pass their written exam.

Marking

The written scenario is manually marked by CREST Assessors. The total marks on this section is 120 marks.

Sample scenario

You can read our sample scenario document online, which contains useful and sample information related to the CREST Certified Tester (CCT) examination scenario component.

The CCT INF written exam is exclusively available in over 1,000 Pearson VUE Test Centres across the globe. You can book your exam now via CREST :: Pearson VUE.

Invigilation

A test centre administrator/invigilator will be present throughout the examination to answer any procedural questions that candidates may have and assist in troubleshooting. The invigilator will not provide any support or advice related to the exam content.

If an issue does occur, a case will be filed. Every effort will be made to accommodate the continuation of your exam and all cases will be investigated and resolved within 3-5 business days. Pearson VUE should provide you with a case ID number. Please ensure you retain this information as this may be required at a later date. 

Communication of results

Written exam

Examination results will be emailed to the candidate within 20 working days of the examination.
