- B. Single tenant
- C. Hosted
- D. Virtual Machine
正解：C
解説：
Correct Answer : 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. Type 2 Hypervisors : Run as an application in a host operating system, rather than in place of an operating system Create a virtual machine and install a guest operating system on it Assign physical resources to a virtual machine and set the amount of processor cores and memory it can use Known as "hosted" Mostly used for end-user virtualization, less frequently used, higher latency Some examples are Oracle VirtualBox and VMware Workstation In-Correct Answers : Virtual Machine : A virtual machine is a virtual representation of physical computer, that behaves like an actual computer. Single Tenant : Sigle tenant means, used by single organization only. Bare metal server are single-tenant physical servers that are dedicated to a single customer. Bare metal servers fulfill the demanding needs of high-performance computing (HPC) and data intense applications. Use cases : Bare metal server are suitable for CPU and I/O intensive workloads.

- B. A security group
- C. A floating in combination with an ACL
- D. An access control list
正解：B
解説：
A security group acts as a virtual firewall that controls the traffic for one or more virtual server instances. A security group is a collection of rules that specify whether to allow or deny traffic for an associated instance. You can associate an instance with one or more security groups and edit the security group rules An Access Control List (ACL) can manage (that is, it can allow or deny) inbound and outbound traffic for a subnet. An ACL is stateless, which means that inbound and outbound rules must be specified separately and explicitly. Each ACL consists of rules, based on a source IP, source port, destination IP, destination port, and protocol. Note : Security Groups control traffic at the virtual service instance level and n Access Control List (ACL) control the traffic at subnet level.

- B. Resource Group
- C. Resource
- D. Zone
- E. Datacenter
正解：C
解説：
Resource : A resource is an instance of a service like Cloudant, a Cloud Foundry application, Virtual Machine, Container. Resources are provisioned globally in an account scope. Resource Group : Resource group is a collection of resources like Virtual Machine, each resource group belongs to an account. all resources are created within a resource group. if a resource group is deleted then all the resources of that particular resource group also deleted. Region : Regions is a physical location with multiple availability zones, Regions are completely independent of each other, They're connected through a dedicated regional low-latency network. each region is located in separate geographic area. Zones : Zones are physically separate locations within each region, that are engineered to be isolated from failures. if we deploy application across two Availability Zones than It increases the availability of an application compared to running in a single Availability Zone. Datacenter : Within an availability zone, We can have multiple data centers. It can simply be a building where infrastructure is managed for a cloud.

- A. Cloud migration
- B. Microservices architecture
- C. DevOps
- D. Portability
正解：A、B、C
解説：
Application modernization is the process of updating outdated business systems and applications. There are many ways to modernize your applications, from integrating existing systems with APIs to doing a full rip-and-replace of infrastructure and building an entirely new application architecture. Common goals of application modernization : - Microservices architecture - DevOps - Cloud migration Benefits of Application modernization : Speed of Development: Since the microservices that make up cloud applications are built once and can be reused over and over, they are easier to use and can be deployed quickly once created. Risk Management: Since one microservice can be used by multiple applications, maintaining security and compliance can be monitored from a central location rather than from within multiple applications. Manage Cost: Since microservices are only written once, the cost to develop them is significantly smaller. The cost to maintain them is also lower since they can be maintained from one central location.
質問 # 31
Which is NOT a characteristic of the cloud defined by NIST?
- A. Broad network access
- B. Rapid elasticity
- C. Resource pooling
- D. On-demand self-service
- E. Self diagnosis
正解：E
解説：
Correct Answers : The Essential Characteristics of Cloud Computing according to NIST : On-demand self-service : A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. Broad network access : Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). Resource pooling: The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, and network bandwidth. Rapid elasticity: Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. Measured service : Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. Self diagnosis: It's self made option, added for distraction.

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.
