質問 # 17
A VxRail architect is designing a 6-node VxRail Cluster for critical applications.
Which two combinations of fault tolerance policies ensure availability of cluster if there is a single data center failure? (Choose two.)
- A. Site disaster tolerance=Site mirroring - stretched cluster
Failures to tolerate=2 failures - RAID 6 (Erasure Coding) - B. Site disaster tolerance=Site mirroring - stretched cluster
Failures to tolerate=No data redundancy - C. Site disaster tolerance=Site mirroring - stretched cluster
Failures to tolerate=2 failures - RAID 1 (Mirroring) - D. Site disaster tolerance=None - standard cluster
Failures to tolerate=1 failure - RAID 5 (Erasure Coding) - E. Site disaster tolerance=Site mirroring - stretched cluster
Failures to tolerate=1 failure - RAID 1 (Mirroring)
正解：C、E
解説：
Site disaster tolerance set to Site Mirroring (stretched cluster) combined with RAID 1 mirroring provides fault tolerance against site failure with the ability to tolerate 2 failures or 1 failure respectively, ensuring data availability during a single data center outage.
質問 # 18
What are two rules for witness on a VxRail stretched cluster? (Choose two.)
- A. It can be managed by a separate vCenter than the one managing the VxRail cluster.
- B. Only a virtual appliance is supported.
- C. The Witness appliance is the same for vSAN ESA and vSAN OSA architecture.
- D. It must be deployed in advance.
- E. It must be the same vSphere version as the VxRail nodes.
正解：A、C
解説：
The witness appliance is the same for both vSAN ESA and OSA architectures, providing consistency across deployments.
The witness can be managed by a separate vCenter server than the one managing the VxRail cluster, allowing flexible management options.
質問 # 19
Which tool is used to create a solution summary for VxRail deployments?
Response:
- A. Live Optics
- B. VMware vCenter
- C. VxRail Sizing Tool
- D. VxRail Manager
正解：C
質問 # 20
When expanding a VxRail cluster, what step ensures seamless integration?
Response:
- A. Running the Initial Configuration Wizard
- B. Upgrading the vCenter Server
- C. Replacing all NICs with 10GbE interfaces
- D. Validating node compatibility
正解：D
質問 # 21
A VxRail architect must design a new VxRail cluster using the VxRail Sizing Tool. The new cluster will replace an existing 3 tier infrastructure and must support Hadoop and Tableau workloads.
Which purpose and use case should be selected in the VxRail sizing tool?
- A. Purpose: Greenfield
Use Case: In Memory database - B. Purpose: Greenfield
Use Case: Big data - C. Purpose: Datacenter Consolidation
Use Case: Relational database - D. Purpose: VxRail Technology Refresh
Use Case: Big data
正解：D
解説：
The cluster is replacing an existing infrastructure, which aligns with a Technology Refresh purpose, and supporting Hadoop and Tableau workloads fits the Big Data use case in the VxRail Sizing Tool.
質問 # 22
What is the primary purpose of reviewing the completed configuration in VxRail Manager?
Response:
- A. Optimizing workload performance
- B. Enabling real-time performance monitoring
- C. Configuring fault tolerance domains
- D. Ensuring accuracy before deployment
正解：D
質問 # 23
When designing vSAN storage policies, what is the backend I/O performance impact when selecting1 failure
- RAID 5 (Erasure Coding)?
- A. Every fronted write generates 4 backend I/Os
- B. Every fronted write generates 3 backend I/Os
- C. Every fronted write generates 7 backend I/Os
- D. Every fronted write generates 0 backend I/Os
正解：D
解説：
Selecting 1 failure tolerance with RAID 5 (Erasure Coding) causes each front-end write to generate 4 backend I/Os due to the parity calculations and data striping involved, impacting storage performance accordingly.
質問 # 24
Which considerations are essential when planning a VxRail deployment?
(Choose two)
Response:
- A. Dynamic Fibre Channel allocation
- B. Default RAID configuration
- C. VLAN configuration for management traffic
- D. Witness host for a two-node cluster
正解：C、D
質問 # 25
Which components are typically part of a VxRail cluster design?
(Choose two)
Response:
- A. Hypervisor license
- B. Witness node
- C. Management switch
- D. Fibre Channel adapter
正解：B、C
質問 # 26
Which considerations are important for VxRail cluster expansion?
(Choose two)
Response:
- A. Migrating witness hosts
- B. Matching node hardware specifications
- C. Ensuring vSphere version consistency
- D. Enabling vSAN encryption
正解：B、C
質問 # 27
During cluster creation in VxRail Manager, which parameter must be specified for networking?
Response:
- A. Witness host IP
- B. Storage pool capacity
- C. Management VLAN ID
- D. vSAN RAID level
