質問 # 49
During a requirements gathering workshop, the customer provides the following requirement:
A new vSphere platform must be designed securely and all interfaces must be protected against potential snooping.
How should this non-functional security requirement be documented?
- A. Unauthorized access to interfaces must be reported within 15 minutes.
- B. Encrypted channels must be used for all communications.
- C. Communications must be through Private VLANs (PVLAN).
- D. Interfaces must be audited.
正解：C
解説：
For example:
"Your ESXi host uses several networks. Use appropriate security measures for each network, and isolate traffic for specific applications and functions. For example, ensure that VMware vSphere vMotion traffic does not travel over networks where virtual machines are located. Isolation prevents snooping. Having separate networks is also recommended for performance reasons."
