An administrator is tasked with expanding an existing 2-node vSAN cluster at a remote site to meet the increasing storage capacity requirement by 30%. The existing cache is underutilized.
Which solution provides the best configuration that maximizes existing ROI?
A. Scale out one more node.
B. Scale out two more nodes.
C. Replace all cache and capacity with larger drives.
D. Add capacity drives to existing disk groups.
正解：D

質問 3：
A solution architect is considering a vSAN Cluster with two hosts per rack. The design should be configured to minimize the potential exposure to rack failure with the capacity to automatically restore compliance with the configured vSAN storage policy.
Which design consideration would minimize potential risks?
A. Create four fault domains and failures to tolerate set to two with Erasure Coding.
B. Create four fault domains and failures to tolerate set to one with mirroring.
C. Create four fault domains and failures to tolerate set to two with mirroring.
D. Create four fault domains and failures to tolerate set to one with Erasure Coding.
正解：B

質問 4：
Which two must be considered when creating a vSAN solution that will utilize VMware vSphere Replication?
(Choose two.)
A. Additional read I/O will be generated by vSphere Replication.
B. Deduplication and compression must be disabled for PIT snapshots,
C. vSAN Encryption cannot be used with vSphere Replication.
D. Point-in-time snapshots count towards component limit.
E. AES-NI must be enabled prior to using snapshots for replication,
正解：A,C

質問 5：
Which three should be taken into consideration when configuring a Stretched Cluster? (Choose three.)
A. vSphere version
B. latency between sites
C. geographical distance
D. bandwidth between sites
E. number of objects
正解：C,D,E

質問 6：
A 4-node vSAN cluster has a single disk group per host. An administrator wants to increase the capacity of the vSAN datastore by adding a second disk group to each host in the cluster. The newer drives intended for the second disk group are certified and in compliance with VMware Compatibility Guide (VCG). However, the newer devices procured are of a different make and model than the existing disk group composition.
Considering the scenario, which statement is true?
A. The Capacity Tier devices need to be the same make and model as other disk groups.
B. This configuration is supported, however performance may vary across disk groups.
C. This configuration is supported, however a separate controller is mandatory for each disk vendor.

D. The Cache Tier devices need to be the same make and model as other disk groups.
正解：A

質問 7：
Reference the exhibit:

Which two statements are accurate considering the state shown In the exhibit? (Choose two.)
A. This vSAN cluster may experience problems with vSAN performance statistics retrieval.
B. This vSAN cluster may exhibit signs of a network partition.
C. The problematic host should be configured to start NTP automatically and connect to the same NTP server as other hosts.
D. The problematic host will partition thus loosing connectivity from the vSAN cluster.
E. The problematic host will experience erratic 10 performance If NTP settings are not corrected.
正解：A,E

質問 8：
An administrator receives an alert for vCenter being unavailable. With vCenter running on vSAN, the administrator wants to know if any other VMs are impacted. What command can an administrator run to determine the overall health of the vSAN objects?
A. esxcli vsan errands timemachine get
B. esxcli vsan cluster get
C. esxcli vsan health cluster list
D. esxcli vsan storage list
正解：B
