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?

- C. The two data center locations have a network latency of 8 ms round-trip time (RTT)
- D. The maximum tolerable data loss is 10 minutes
正解：C
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 # 117
An architect is designing a series of new vSphere environments for an organization. The environments will be deployed in their US-East and US-West region data centers. Each data center may have one or more dedicated vSphere environments. Only the vSphere environments within a data center will be configured with Enhanced Linked Mode.
The Chief Technology Officer (CTO) has authorized the use of VMware vRealize Automation Cloud for automation. The build team creates standardized virtual machine images for various operating systems in Open Virtualization Format (OVF) and publishes the latest version on an asneeded basis to an internal HTTPS-accessible repository.
The architect must design a content library topology that meets the following requirements:
- A localized content library must be available in each data center.
- Each content library must be updated when an image is updated and released by the build team.
- The cloud automation platform must be able to consume the latest approved content library images.
- It must leverage the existing build team processes.
What should the architect recommend to meet the requirements?
- A. Work with the build team to automate a JSON-based manifest to the repository when changes occur in the repository. Create a subscribed content library for each vSphere environment. Configure the content library to download content when needed.
- B. Work with the build team to create a local content library for each vSphere environment. Import the OVF images when new image are published to the repository.
- C. Work with the build team to automate a JSON-based manifest to the repository when changes occur in the repository. Create a subscribed content library for each vSphere environment. Configure the content library to download content automatically.
- D. Create a local content library for the primary vSphere environment in each data center. Create a subscribed content library for each additional vSphere environment in each data center. Configure the content library to download content automatically.
正解：C

- D. Small
正解：A
解説：
In this case, 200 ESXi + 800 VMs, therefore Medium (up to 400 ESXi or 4000 VMs) For more details:
- Tiny environment (up to 10 hosts or 100 virtual machines)
- Small environment (up to 100 hosts or 1,000 virtual machines)
- Medium environment (up to 400 hosts or 4,000 virtual machine)
- Large environment (up to 1,000 hosts or 10,000 virtual machines)
- X-Large environment (up to 2,500 hosts or 45,000 virtual machines)

質問 # 120
A VMware Service Provider is tasked with delivering a solution for continuous availability for a subset of Tier 1 virtual machines (VMs) and vApps running in their vSAN environment. The VMs make up a mission-critical application and there can be no data loss in the event of an outage at their primary data center. In the event of a regional outage, they have established a 10-minute recovery point objective (RPO). Failover/failback to the third site must be automated.
They have the following in place:
- Two local data centers (primary and secondary) connected with 100 Gb dedicated fiber
- 2ms round-trip time (RTT) latency between the sites
- A third data center located on another power grid
- 70ms latency between the primary and secondary data centers
- Matching storage arrays at all locations
Which two solutions could be used to meet the requirements- (Choose two.)
- A. vSphere Data Protection
- B. vSAN Metro Cluster
- C. vStorage APIs for Array Integration (VAAI)
- D. Site Recovery Manager
- E. Snapshots
正解：B、D
解説：
Metro is a stretched-cluster, vSAN tolerates 5ms to main sites first-second and 150ms to a third site where a witness vm will stay, all details are correct till now. Matching storage arrays at all locations seems to be, or its a single datastore presented to infrastructure itself. As the third site has an infrastructure established as well can be used to replicate VMs from the stretched datastore from first-second, the need of Site Recovery.

質問 # 127
An architect is designing a vSphere environment for a customer based on the following information:
- The vSphere cluster will have three hosts only due to budget considerations.
- A database cluster (node majority) consisting of three virtual machines will be running on the vSphere cluster.
Which two recommendations can the architect make so that the customer achieves the highest level of application availability while taking into consideration operational resiliency- (Choose two.)
- A. Set das.respectvmvmantiaffinityrules to false
- B. Disable vSphere HA during maintenance
- C. Set das.ignoreinsufficienthbdatastore to true
- D. Create VM-VM anti-affinity rules
- E. Create VM-Host anti-affinity rules
正解：A、D
解説：
das.respectvmvmantiaffinityrules
Determines if vSphere HA enforces VM-VM anti-affinity rules. The default value is "true" and rules are enforced even if vSphere DRS is not enabled. In this case, vSphere HA does not fail over a virtual machine if doing so violates a rule, but it issues an event reporting there are insufficient resources to perform the failover. This option can also be set to "false", whereby the rules are not enforced.
