- A
Obtain written authorization from the third-party provider
Correct. Authorization from the third party is necessary.
- B
Scan only the IP addresses that resolve to the client's domain
Why wrong: This does not resolve the permission issue.
- C
Continue testing as long as the target is in scope
Why wrong: Testing a third-party without permission is a violation of terms of service and may be illegal.
- D
Ignore the web application and test only on-premises assets
Why wrong: The application is in scope, but testing requires permission.
Question 206 of 1,000
PT0-002 Planning and Scoping Practice Question
This PT0-002 practice question tests your understanding of planning and scoping. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During an external penetration test, the tester discovers that a critical web application is hosted on a third-party cloud provider. The SOW did not mention this provider. What should the tester do before proceeding with testing against that provider's infrastructure?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Obtain written authorization from the third-party provider
Testing third-party services requires explicit permission from the provider to avoid legal and contractual issues.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Obtain written authorization from the third-party provider
Why this is correct
Correct. Authorization from the third party is necessary.
Related concept
Authentication checks who the user is.
- ✗
Scan only the IP addresses that resolve to the client's domain
Why it's wrong here
This does not resolve the permission issue.
- ✗
Continue testing as long as the target is in scope
Why it's wrong here
Testing a third-party without permission is a violation of terms of service and may be illegal.
- ✗
Ignore the web application and test only on-premises assets
Why it's wrong here
The application is in scope, but testing requires permission.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related PT0-002 questions on access control and AAA configuration.
