- A
Provide the vendor with access to the guest Wi-Fi network
Why wrong: Guest Wi-Fi is usually isolated and may not allow access to internal systems; it also lacks strong authentication and encryption for sensitive work.
- B
Set up a VPN connection with two-factor authentication
A VPN creates an encrypted tunnel, and two-factor authentication ensures the vendor's identity is verified, providing secure remote access.
- C
Allow the vendor to use remote desktop protocol (RDP) directly over the internet
Why wrong: Direct RDP over the internet is insecure and commonly targeted by attackers; it should be used only through a secure gateway or VPN.
- D
Create a local user account with administrative privileges for the vendor
Why wrong: Granting administrative privileges violates the principle of least privilege and increases the risk of unauthorized changes or data breaches.
Quick Answer
The answer is to set up a VPN connection with two-factor authentication, as this is the best practice for secure vendor access in IT projects. A VPN creates an encrypted tunnel over the internet, ensuring data confidentiality and integrity during transmission, while two-factor authentication adds a critical second layer of security beyond a simple password, preventing unauthorized access even if credentials are compromised. On the CompTIA Project+ PK0-005 exam, this scenario tests your understanding of balancing operational needs with security controls—specifically, that vendor access must be both encrypted and authenticated. A common trap is choosing a simple password policy or a firewall rule alone, which fails to protect data in transit or verify the vendor’s identity. Remember the mnemonic “VPN + 2FA = Trusted Tunnel” to recall that encryption and multi-factor authentication together form the gold standard for granting external parties secure network entry.
PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
This PK0-005 practice question tests your understanding of basics of it infrastructure and it project management. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
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?

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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may 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.
Detailed technical explanation
How to think about this question
A VPN uses protocols such as IPsec or TLS to encapsulate and encrypt all traffic between the vendor's device and the corporate network, ensuring that sensitive data like CRM configuration files and credentials are not transmitted in plaintext. Two-factor authentication (2FA) typically combines something the vendor knows (password) with something they have (e.g., a time-based one-time password from an authenticator app), mitigating the risk of credential theft. In real-world scenarios, organizations often deploy a dedicated VPN concentrator with split tunneling disabled to force all vendor traffic through the encrypted tunnel, preventing accidental data leaks.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
