質問 # 24
An architect is tasked with designing a greenfield VMware software-defined data center (SDDC) solution that will be used to deliver a private cloud service for a customer.
During the initial meeting with the service owner and business sponsor, the customer has provided the following information to help inform the design:
The solution must initially support the concurrent running of 300 production and 600 development virtual machines.
The production environment should be delivered across two geographically dispersed data centers. The development environment must be vSphere-based but does not have to be deployed on-premises.
The two data centers are connected to each other through multiple diversely routed, high bandwidth and low latency links.
The customer's server hardware standard document states that all virtual infrastructure hosts must be based on blade architecture only.
The service owner has said that is important to ensure that neither the availability target of 99.5% nor the resource capacity is affected when the operations team completes maintenance activities, such as the monthly software patching and ad-hoc hardware break/fix.
All virtual machine backups must be completed using the existing backup service. The recovery time objective (RTO) for the service is four hours.
The recovery point objective (RPO) of the service is 24 hours.
Given the information from the customer, which two would be classified as assumptions within the design? (Choose two.)
- A. The customer will update their hardware standard to support rack mount servers
- B. The backup service will store data in a secure facility
- C. The clusters will have a minimum redundancy of N+1
- D. All virtual machines will be deployed with the same resource profile for production and development
- E. The backup service has sufficient capacity for the new requirements
正解：C、E
解説：
B) The backup service has sufficient capacity for the new requirements
"All virtual machine backups must be completed using the existing backup service." The existing backup service may not have capacity or compatabiltiy for the new SDDC E) The clusters will have a minimum redundancy of N+1
"The service owner has said that is important to ensure that neither the availability target of 99.5% nor the resource capacity is affected when the operations team completes maintenance activities" We assume N+1 is sufficient. They may require a higher level of redundancy.

質問 # 26
During a requirements gathering workshop to design a physical to virtual migration, the customer provides the following information:
There is no physical firewall in the data center with no anticipated plans for a future network refresh.
Leveraging the virtual infrastructure to mitigate the lack of network security must be addressed in the design.
All physical servers to be migrated exist on the same VLAN.
Which recommendation should the architect make to address the customer requirement with regard to virtual networking?
- A. Disable traffic filtering and marking Use tag actions
- B. Split the virtual machines into several VLANs
Use tag actions - C. Enable traffic filtering and marking
Use allow or drop actions - D. Create port groups with different names and same VLAN IDs
Enable traffic shaping for ingress and egress traffic
正解：C
解説：
In a vSphere distributed switch, by using the traffic filtering and marking policy, you can protect the virtual network from unwanted traffic and security attacks or apply a QoS tag to a certain type of traffic. The traffic filtering and marking policy represents an ordered set of network traffic rules for security and for QoS tagging of the data flow through the ports of a distributed switch. In general, a rule consists of a qualifier for traffic, and of an action for restricting or prioritizing the matching traffic.

質問 # 32
An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.
The platform has recently commissioned new hosts to update the development cluster.
The development cluster host configuration is:
4 ESXi hosts with 2 sockets * 16 cores
512 GB RAM divided evenly between sockets
There is no resource contention
The benchmarking cluster host configuration is:
8 ESXi hosts with 2 sockets * 8 cores
256 GB RAM divided evenly between sockets
There is no resource contention
The customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster. Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data.
