Dell EMC Professional – Backup Recovery Solutions Design v3 — Question 24

A customer wants to use the service of an external network operation center (NOC) / security operation center (SOC) to monitor the CR Vault environment.
What is the most secure solution if the customer wants to ensure that communication is only possible to the NOC/SOC?

Answer options

• A. Firewall
• B. Dedicated Network Link
• C. Data Diode
• D. VPN Tunnel

Correct answer: C

Explanation

The Data Diode is the best choice because it allows data to flow in only one direction, ensuring that communication is securely restricted to the NOC/SOC. A Firewall, Dedicated Network Link, and VPN Tunnel do not provide the same level of unidirectional data flow, which could expose the CR Vault environment to potential risks.
