問題 #76
A VCF Deployment Specialist is sizing a vSAN ESA Stretched Cluster for VCF 9.0 to support a massive cross-site Disaster Recovery requirement.
```
[SDDC Manager - Workload Domain Configuration]
Topology: Stretched Cluster
Witness: Dedicated Witness Appliance (Third Site)
Max Scale Supported: [ ? ]
```
What are the officially supported maximum scale limits for a standard vSAN 8.0/9.0 Stretched Cluster topology? (Select all that apply.)

A. A single Stretched Cluster requires a minimum of 2 separate Witness Appliances (one for each site) to handle the 60-host metadata load.
B. The maximum size of the Stretched Cluster is 60 data hosts in total, evenly divided into 30 hosts in the Preferred Site and 30 hosts in the Secondary Site.
C. Stretched clusters strictly require the vSphere Enterprise Plus and vSAN Advanced licenses; vSAN Standard is not sufficient.
D. A Stretched Cluster topology supports a maximum of 1 active Witness Appliance per cluster.
E. The maximum supported RTT (Round Trip Time) network latency between the Preferred and Secondary sites is strictly 5 milliseconds to support the synchronous Write I/O operations.

答案：B,D,E

問題 #77
A CTO is evaluating how to handle Site Maintenance and Site Failover testing for a VCF Stretched Cluster. The infrastructure team prefers using vSphere Distributed Resource Scheduler (DRS) Host/Site Affinity rules to automate VM movements, rather than using SRM.
The CTO examines the architectural trade-offs of relying purely on DRS rules versus an SRM Recovery Plan.
Which of the following statements accurately describe the trade-offs and mechanics of using DRS Affinity Rules for Site Failover in a Stretched Cluster? (Select all that apply.)

A. "Must run on Preferred Site" affinity rules are an anti-pattern for DR; if the Preferred Site fails, vSphere HA is strictly forbidden from restarting these VMs on the Secondary Site, negating the disaster recovery value.
B. DRS site affinity rules automatically override the vSAN "Site Locality" algorithm, forcing data components to migrate to the same site as the compute.
C. A primary limitation of DRS-based failover is that it cannot control the startup order (IP address updates, dependencies) of virtual machines after they restart on the remote site.
D. SRM testing requires pausing the vSAN synchronous mirror, whereas DRS-based testing allows VMs to move freely between sites without breaking RPO.
E. "Should run on Preferred Site" affinity rules allow VMs to be easily vMotioned to the Secondary Site for maintenance, and vSphere HA will still restart them on the Secondary Site during a real disaster.

答案：A,C,E

問題 #78
Which protocol is commonly used for external storage integration?

A. FTP
B. HTTP
C. SMTP
D. iSCSI

答案：D

問題 #79
A VI Admin is planning the expansion of a 3-node vSAN cluster to a 6-node vSAN cluster. The 3- node cluster is currently operating near maximum safe capacity due to the strict "Host Rebuild Reserve" threshold.
```
[Log Snippet: vmkernel.log - Capacity Daemon]
2026-11-20T10:00:00Z WARN vsan-dom - Host Rebuild Reserve active: 33%
of Raw Capacity locked.
2026-11-20T12:00:00Z INFO vpxd - Cluster expansion complete. Host
count: 6.
2026-11-20T12:05:00Z INFO vsan-dom - Host Rebuild Reserve recalculated:
[ ? ]%
```
How does the physical expansion of the cluster mathematically alter the "Host Rebuild Reserve" percentage, and what is the direct impact on usable VM capacity?

A. The required reserve percentage automatically decreases from 33% down to approximately 16%; this releases a significant portion of previously "locked" storage on the original hosts back into the usable VM capacity pool.
B. The reserve percentage remains fixed at 33% to comply with the FTT=1 storage policy, meaning usable capacity scales linearly but overhead remains high.
C. The reserve percentage increases to 50% because a 6-node cluster inherently carries a higher statistical risk of dual-host failures.
D. The log indicates that Host Rebuild Reserve is disabled automatically upon reaching 6 nodes because Distributed Resource Scheduler (DRS) handles capacity allocation above the 4-node threshold.

答案：A

問題 #80
An administrator is troubleshooting a vSAN performance issue. In the vSAN cluster performance charts there is a high latency on the vSAN cluster.
What is a possible cause of the performance issue?

A. There is congestion in one or more disk groups.
B. Jumbo frames are enabled on the VMkernel adapters.
C. The Virtual Machines are using PVSCSI controllers.
D. Erasure Coding is disabled in the storage policy.

答案：A

解題說明：
High latency in a vSAN cluster is commonly caused by congestion in the backend storage path. Disk group congestion means vSAN is queuing, delaying, or throttling I/O because one or more disk groups cannot service the workload at the required rate. VCF Operations and vSAN performance views expose disk group and device-level congestion indicators, including IOPS congestion, log congestion, component congestion, memory congestion, and SSD congestion. These metrics directly correlate with elevated latency because the virtual machine I/O path must wait for vSAN backend processing to complete. PVSCSI controllers are normally recommended for high-performance virtual disks and are not a typical cause of vSAN latency. Jumbo frames, when consistently configured end-to-end, are a valid network optimization and do not inherently cause latency. Disabled erasure coding would usually reduce parity overhead, not create backend latency. Therefore, disk group congestion is the most likely explanation for high latency shown in the vSAN cluster performance charts. Reference topics: vSAN Performance Service, Disk Group Metrics, Congestion Metrics, vSAN Latency Troubleshooting.
