質問 # 14
In a stretched vSAN cluster, how is Read Locality established after fail over to the secondary site?
- A. 50% of the reads comes from vSAN hosts on the remote site
- B. 50% of the reads comes from vSAN hosts on the local site
- C. 100% of the reads comes from vSAN hosts on the local site
- D. 100% of the reads comes from vSAN hosts on the remote site
正解：C
解説：
vSAN stretched clusters uses a read locality algorithm to read 100% from the data copy on the local site. Read locality reduces the latency incurred during reading operations.

質問 # 16
A customer is planning to deploy a vSAN cluster to host their in-house distributed ERP system.
The hardware specifications for their server nodes include:
* 2 x Intel Xeon CPU E5-2697 v3 @ 2.60GHz
* 1TB memory
Which boot device is supported for the vSAN ESXi nodes for this customer?
- A. A 16GB single-level cell (SLC) SATADOM device must be used.
- B. A 4GB USB or SD device must be used.
- C. ESXi Hosts must boot from a PMEM device.
- D. A 16GB multiple-level cell (MLC) SATADOM device must be used.
正解：A
解説：
If the memory of the ESXi host has 512 GB of memory or less, you can boot the host from a USB, SD, or SATADOM device.
If the memory of the ESXi host has more than 512 GB, consider the following guidelines.
You can boot the host from a SATADOM or disk device with a size of at least 16 GB. When you use a SATADOM device, use a single-level cell (SLC) device.
