質問 # 92
An architect is reviewing a physical storage design. The customer has specified that storage DRS will be used for ease of operational management for capacity and performance.
Which recommendation should the architect include in the design?
- A. Create more datastores within each Storage DRS cluster to balance space and performance
- B. Create smaller datastores to balance space with Storage DRS
- C. Use a larger number of storage profiles (varied disk speeds and RAID levels) to improve performance
- D. Create larger datastores to balance space with Storage DRS
正解：A
解説：
You could create 2x 64TB LUNs, 4x 32TB LUNs, 16x 8TB LUNs or 32x 4TB LUNs. When there are more datastores, SDRS will have more option to find right datastore to fit the virtual machine to placed or moved.
質問 # 93

質問 # 94
As part of a new hybrid cloud initiative for a large financial company, the customer technical team is presenting an overview of the current state of the infrastructure and their vision for a new solution.
The project team captures notes during the presentation and adds them to the discovery documentation.
Which of the listed statements is a design constraint?
- A. The two data center locations have a network latency of 8 ms round-trip time (RTT)
- B. The existing storage is out of maintenance
- C. The maximum tolerable data loss is 10 minutes
- D. The applications are created in-house with in-guest recovery protection
正解：A
解説：
Customer talks about a new Hybrid cloud solution. Therefore, vSAN comes to my mind as a great solution regarding storage and Hybrid cloud.
Based on the following information, network latency of 8 ms RTT will be considered a design constraint.
Data Site to Data Site Network Latency :
Data site to data site network refers to the communication between non-witness sites, in other words, sites that run virtual machines and hold virtual machine data. Latency or RTT (Round Trip Time) between sites hosting virtual machine objects should not be greater than 5msec (<
2.5msec one-way).

質問 # 95
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
質問 # 96

- The DevOps team must be able to regularly check out a copy of the image for updates and check in a new version of the image.
- Images must be synchronized from the primary data center to the new data center.
Which three recommendations should the architect make to design a content library solution that will meet these requirements- (Choose three.)
- A. Create a subscribed library from the published library and synchronize Open Virtualization Format (OVF) templates automatically
- B. Create a subscription and publish VM templates to a subscribed content library
- C. Update the role for the DevOps team with new privileges

質問 # 99
An architect is preparing a design for a customer. Based on requirements, the architect recommends an HCI- based infrastructure with all-flash architecture. During the assessment, it is confirmed that the network throughput generated by virtual machines does not exceed 150 Mb/s.
What is the minimum number and type of network adapters in each server that the architect can recommend to ensure requirements are met and there is no single point of failure?
- A. Two 10 GbE network adapters per server
- B. Four 10 GbE network adapters per server
- C. Four 1 GbE network adapters per server
- D. Two 1 GbE network adapters per server
正解：A
質問 # 100
A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.
Per the defined logical network configuration, there are two network adapters each used for:
- Management traffic
- vMotion traffic
- iSCSI traffic
- Virtual machine traffic
Which design decision should the architect make to meet the customer requirement?
- A. Configure a dedicated TCP/IP stack for vMotion traffic.
- B. Combine vMotion and Management traffic to make use of four adapters.
- C. Use Network I/O Control to define a reservation for vMotion traffic.
- D. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
正解：D
解説：
We maintain the 2 x 1 GbE network adapters for vMotion and then configure multiple VMkernel interfaces using the same NIC and network. Each time you add a VMkernel adapter and enable it for vMotion, you create a new stream. With more streams, there is greater bandwidth utilization.

正解：A
質問 # 103
An architect is tasked with recommending a solution for a company that is running out of VLANs.
Currently the company is running two separate data centers based on vSphere including an Enterprise Plus license.
In the first data center, the problem was solved by using VMware NSX and overlay network. In the second data center, there is currently no VMware NSX implementation in place and no budget for additional licenses.
What should the architect recommend as a potential solution to provide support for additional VLANs?
- A. Separate Distributed Virtual Switches (DVS)
- B. Virtual Guest Tagging (VGT)
- C. vSwitch VLAN Tagging (VST)
- D. Private VLANs (PVLAN)
正解：D
質問 # 104
An architect is tasked with expanding an existing VMware software-defined data center (SDDC) solution so that it can be used to deliver a virtual desktop infrastructure (VDI) service off-shore development activities.
The production environment is currently delivered across two geographically dispersed data centers. The two data centers are currently connected to each other through multiple diversely routed, high bandwidth and low latency links.
The current operations management components are deployed to a dedicated management cluster that is configured with N+1 redundancy. The current VMware software-defined data center (SDDC) has a monthly availability target of 99.5%, which includes all management components.
The customer requires that the new solution scale to support the concurrent running of 500 persistent virtual desktops. The virtual desktops must not share the same virtual infrastructure as existing virtual machines, but can be managed using the same VMware operations management components.
Any new VDI service management components must be installed into the management cluster. There is no requirement to back up the virtual desktops because all relevant user data is stored centrally. The VDI service is providing business critical services and must have an availability target of 99.9%.
Given the information from the customer, which two assumptions would the architect include in the design? (Choose two.)
- A. The VDI service has a higher service-level agreement (SLA) than the operations management SLA
- B. The existing management cluster has enough available capacity to host any VDI service management component
- C. The management cluster has N+1 redundancy
- D. The existing virtual infrastructure has sufficient capacity to host the new VDI workloads
- E. The existing operations monitoring tools have sufficient capacity to monitor the new VDI services
正解：B、E
質問 # 105
