質問 # 35
An architect is designing a solution for an environment with two types of resource profiles that must be virtualized. The first type consists of Tier 1 virtual machines that are disk I/O intensive, but do NOT require high CPU or memory. The second type consists of Tier 2 virtual machines that require a lower CPU and memory allocation and have minimal disk I/O.
Which design recommendation should the architect make for distributing the resource profiles?
- A. Separate the two resource profiles into two clusters. The Tier 2 cluster will have faster CPU and more memory while the Tier 1 cluster will have slower CPU and less memory but more disk space.
- B. Run both resource profiles on the same cluster with the same host hardware platform.
- C. Run both resource profiles on the same cluster with host hardware that has fast CPU, large amounts of memory, and the fastest storage platform.
- D. Separate the two resource profiles into two clusters. The Tier 1 cluster will have fast storage while the Tier 2 cluster will not.
正解：D
解説：
Checked in the training manual, chapter 10 Infrastructure Manageability: When mention about tiers... always talks about DIFFERENT CLUSTERS. Vmware suggest this in order to calculate spare hosts, cpu contention, disk performance, etc. In this case B and D should be disregarded, you should not mix Tier 1 and 2 in the same cluster.
