- A. Hypervisor
- B. dBase
- C. Bare metal server
- D. Virtual Machine
正解：C
解説：
Correct Answer : Bare Metal Server is a dedicated to a single customer only. Bare metal servers are suitable for big data analytics applications and GPU-intensive solutions. Bare metal servers satisfies workload examples such as ERP, CRM, AI, deep learning and virtualization. In-Correct Answers : Virtual Machine : A virtual machine is a virtual representation of physical computer, that behaves like an actual computer. Hypervisor is a small software layer that enables multiple operating systems to run alongside each other. Hypervisor separates the VMs logically, assigning each its own slice of underlying computing power, memory, and storage. There are 2 types of Hypervisor : Type 1 & Type 2. Hosted is another name given to a Type 2 hypervisor. dBase : dBase was one of the first database management systems for microcomputers.

質問 # 80
Which of the following are benefits of serverless computing? (Select Three)
- A. Automatic tooling
- B. API Management
- C. Pay for execution only
- D. Integrated event sources
正解：B、C、D
解説：
Serverless computing is a cloud computing execution model that provisions computing resources on demand and offloads all responsibility for common infrastructure management tasks. They are auto scalable so it can handle extremely active traffic periods.
Serverless computing does-not means there are no physical servers utilized, of course there are servers, but we don't have to manage them, in background cloud provider manage (provisioning, scheduling, scaling, patching and more) for us, this gives developers more time to develop and optimize their front-end application code and business logic. And with serverless, customers never pay for idle capacity. They pay only for the resources required to run their applications, and only when those applications are running.
Serverless is a polyglot environment, enabling developers to code in any language or framework - Java, Python, node.js - with which they're comfortable. Because serverless scales up and down on demand in response to workload, it offers significant cost savings for spiky workloads. But it does not offer the same savings for workloads characterized by predictable, steady or long-running processes; in these cases, a traditional server environment might be simpler and more cost-effective.
Serverless Implementations differ across service providers, and capabilities vary, including supported runtimes, authentication, scaling and monitoring.
Serverless architectures are well-suited for event-driven, IOT and stream-processing workloads most notably open-source Apache Kafka event streaming platform.
Benefits:
- Pay only for the time for our code will run.
- Developer don't have to take care of servers or infrastructure, it maintains by cloud provider, so they can focus more on development and business logic.
- API Management & Integrated event sources.
- Serverless scales up and down on demand in response to workload

質問 # 82
A virtualized, multi-tenant architecture enabling tenants or users to share computing resources residing outside their firewalls best describes a characteristic for which cloud type?
- A. Hybrid Cloud
- B. Public Cloud
- C. Private Cloud
正解：B
解説：
Public Cloud is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider. In a public cloud model, users get access to servers, storage, network, security, and applications as services delivered by cloud service providers over the internet maintain by the cloud provider. Characteristics of a public cloud: A public cloud is a virtualized multi-tenant architecture enabling tenants or users to share computing resources, residing outside their firewalls. Use Case : Now a days, Organizations are using public cloud computing resources to build secondary infrastructures for disaster recovery, data protection, and business continuity. In-Correct Answer : Private Cloud is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises. Community Cloud is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. Hybrid Cloud is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

質問 # 87
Which of the following are types of Application virtualization? (Select Three)
- A. CPU visualization
- B. Local application virtualization
- C. Application streaming
- D. Server-based application virtualization
- E. Server-defined networking (SDN) visualization
正解：B、C、D
解説：
Application virtualization: Application virtualization runs application software without installing it directly on the user's OS. This differs from complete desktop virtualization (mentioned above) because only the application runs in a virtual environment-the OS on the end user's device runs as usual. There are three types of application virtualization:
Local application virtualization: The entire application runs on the endpoint device but runs in a runtime environment instead of on the native hardware.
Application streaming: The application lives on a server which sends small components of the software to run on the end user's device when needed.
Server-based application virtualization : The application runs entirely on a server that sends only its user interface to the client device.

質問 # 91
Which cloud storage have poor performance when data needs to be shared ?
- A. Object Storage
- B. Block Storage
- C. File Storage
- D. Direct Attached
正解：D
解説：
Direct area storage, also known as direct-attached storage (DAS), is as the name implies. DAS is a storage device which directly connected to your computer or server, if often connected to a single machine only. Some examples of direct attached storage are floppy disks, optical disc, compact discs (CDs) and digital video discs (DVDs), hard disk drives (HDD), flash drives and solid-state drives (SSD). DAS is often connected with single computing machine only so sharing capabilities are limited and poor. Block storage is highly available and resilient and will often include data encryption at rest and in transit. Block storage, is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Block storage suitable for low latency workloads where consistently high speeds required. File Storage associated with Network Attached Storage (NAS) technology. File Storage organizes files in a hierarchy of named directories. The ability for File Storage to be mounted to multiple compute nodes at a time make it an ideal solution for common storage requirements. Object Storage enable you to store and access unstructured data anywhere in the world with a self-service portal backed by RESTful APIs. Object Storage supports exponential data growth and cloud-native workloads with built-in high-speed file transfer capabilities, cross-region offerings and integrated services. Use cases : Backup and recovery, Data archiving, Cloud-native application, AI and big data analytics.
