PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
A project manager is overseeing the implementation of a new customer relationship management (CRM) system. The vendor requires access to the company's internal network to install and configure the software. Which of the following is the BEST practice to ensure security while allowing vendor access?
⚠ Common exam trap
A common mix-up: candidates think providing a local admin account (Option D) is sufficient for security, overlooking the need for encrypted communication and multi-factor authentication, which are critical for remote vendor access in a production environment.

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
✓
Set up a VPN connection with two-factor authentication
Setting up a VPN connection with two-factor authentication is the best practice because it creates an encrypted tunnel over the internet, ensuring data confidentiality and integrity, while two-factor authentication adds an extra layer of security beyond just a password. This approach allows the vendor to access only the internal network resources necessary for installation and configuration, without exposing the entire network to unauthenticated or unencrypted 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.
- ✗
Provide the vendor with access to the guest Wi-Fi network
Why it's wrong here
Guest Wi-Fi is usually isolated and may not allow access to internal systems; it also lacks strong authentication and encryption for sensitive work.
- ✓
Set up a VPN connection with two-factor authentication
Why this is correct
A VPN creates an encrypted tunnel, and two-factor authentication ensures the vendor's identity is verified, providing secure remote access.
- ✗
Allow the vendor to use remote desktop protocol (RDP) directly over the internet
Why it's wrong here
Direct RDP over the internet is insecure and commonly targeted by attackers; it should be used only through a secure gateway or VPN.
- ✗
Create a local user account with administrative privileges for the vendor
Why it's wrong here
Granting administrative privileges violates the principle of least privilege and increases the risk of unauthorized changes or data breaches.
