A customer requests a review of its current vSphere platform design.
The following information is noted:
There are three different workload profiles for the virtual machines:
Tier-1 virtual machines operate resource-intensive applications and require dedicated allocations for CPU and RAM.
Tier-2 virtual machines operate internet-facing applications and require access to externally facing networks.

質問 # 67
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. Interfaces must be audited.
- B. Unauthorized access to interfaces must be reported within 15 minutes.
- C. Encrypted channels must be used for all communications.
- D. Communications must be through Private VLANs (PVLAN).
正解：D
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."
