Suppose you have two types of applications: legacy applications that require specialized mainframe hardware and newer applications that can run on commodity hardware. Which cloud deployment model would be best for you?
A.public cloud
B.private cloud
C.hybrid cloud
2.
You're developing an application and want to focus on building, testing, and deploying. You don't want to worry about managing the underlying hardware or software. Which cloud service type is best for you？
A. Infrastructure as a Service (IaaS)
B. Platform as a Service (PaaS)
C. Software as a Service (SaaS)
3.
Which term from the list below would be viewed as benefits of using cloud services?
A. Unpredictable costs
B. Elasticity
C.Local reach only
4.
True or False: Azure provides flexibility between capital expenditure (CapEx) and operational expenditure (OpEX).
False,没有CapEx了
5.
True or False: An organization that hosts its infrastructure in a private cloud can decommission its data center.
True,要看怎么理解这个its data center，是否是组织原来自己组建的data center
6.
True or False: Your company plans to migrate all its data and resources to Azure. The company’s migration plan states that only platform as a service (PaaS) Solutions must be used in Azure. You need to deploy an Azure environment that supports the planned migration. Solution: You create an Azure App service and Azure virtual machines that have Microsoft SQL Server installed.
False. virtual machine是IaaS了，但是迁移计划里面，说了只有PasS
Azure SQL Database is a fully managed platform as a service (PaaS) database engine that handles most of the database management functions such as upgrading, patching, backups, and monitoring without user involvement.
Azure SQL is a family of managed, secure, and intelligent products that use the SQL Server database engine in the Azure cloud.

You plan to migrate a web application to Azure. The web application is accessed by external users. You need to recommend a cloud deployment solution to minimize the mount of administrative effort used to manage the web application. What should you include in the recommendation?
A. Software as a Service (SaaS)
B. Platform as a Service (PaaS)
C. Infrastructure as a Service (IaaS)
8.
True or False: You plan to deploy several Azure virtual machines. You need to ensure that the services running on virtual machines are available if a single data center fails. Solution: You deploy the virtual machines to two or more availability zones.
True
Azure Availability Zones are unique physical locations within an Azure region and offer high availability to protect your applications and data from datacenter failures. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking.
The physical separation of availability zones within a region protects apps and data from facility-level issues. Zone-redundant services replicate your apps and data across Azure Availability Zones to protect from single points of failure.
9.
Your company plans to migrate several servers to Azure virtual machines. You need to identify which administrative responsibilities will be reduced after the planned migration. Which two responsibilities should you identify?(多选题)
选A和C，虽然不知道A是什么
A. replacing failed server hardware
B. managing physical server security
C. backing up application data and updating server operating systems
正确答案应该是A和B，这里问题说是，迁移到azure的虚拟机之后，可以减轻哪些原有的责任。因为迁移到了虚拟机，所以，本来自己维护的物理机器，需要更换换掉的服务器硬件，并且要确保服务器的安全(空调降温，防火)，这两件事情不用做了。
网上找了更复杂的原题，
- A. Replacing failed server hardware
- B. Backing up application data
- C. Managing physical server security
- D. Updating server operating systems
- E. Managing permissions to shared documents
Suggested Answer: AC
Azure virtual machines run on Hyper-V physical servers. The physical servers are owned and managed by Microsoft. As an Azure customer, you have no access to the physical servers. Microsoft manage the replacement of failed server hardware and the security of the physical servers so you donג€™t need to.
Incorrect Answers:
B: Microsoft have no control over the applications you run on the virtual machines. Therefore, it is your responsibility to ensure that application data is backed up.
D: Microsoft do not manage the operating systems you run on the virtual machines. Therefore, it is your responsibility to ensure that the operating systems are updated.
E: Microsoft have no control over the shared folders you host on the virtual machines. Therefore, it is your responsibility to ensure that folder permissions are configured appropriately.

You have an application named App1.
App1 has low usage during the first weeks of each month and very high usage during the last week of each month.
Which benefit of Azure of Azure Cloud Services supports cost management for this type of usage pattern?
A. high availability
B. elasticity
C.load balancing
Capex are used by a company to acquire or upgrade physical assets such as equipment, property, or industrial buildings.
An operating expense, operating expenditure, operational expense, operational expenditure or OPEX is an on-going cost for running a product, business, or system.
CAPEX，全称为Capital Expenditure，即资本性支出，一般是指资金或固定资产、无形资产、递延资产的投入。这类资产在使用过程中会持续多个计费期间，需要在使用过程中将其资本化，并分期将成本转为费用。如固定资产的折旧，无形资产和递延资产的摊销等。对电信运营商来说，网络设备、计算机、仪器等一次性支出的都属于CAPEX。
OPEX是(Operating Expense)指的是企业的管理支出、办公室支出、员工工资支出和广告支出等日常开支。
在电信运营商领域，被称为运营成本,
计算公式为:OPEX=维护费用+营销费用+人工成本(+折旧)。
运营成本主要是指当期的付现成本。
CAPEX一般是指资金、固定资产的投入.对电信运营商来说,有关的网络设备、计算机、仪器等一次性支出的项目都属于CAPEX,其中网络设备占最大的部分。
OPEX指的是企业的管理支出。
