質問 # 47
Which of the following are types of virtualizations? (Select Three)
- A. Region virtualization
- B. Application virtualization
- C. Data center virtualization
- D. CPU visualization
正解：B、C、D
解説：
Virtualization is a process that allows for more efficient utilization of physical computer hardware and is the foundation of cloud computing.
Types of virtualization:
CPU (central processing unit) virtualization is the fundamental technology that makes hypervisors, virtual machines, and operating systems possible. It allows a single CPU to be divided into multiple virtual CPUs for use by multiple VMs.
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.
Data center virtualization abstracts most of a data center's hardware into software, effectively enabling an administrator to divide a single physical data center into multiple virtual data centers for different clients.
Each client can access its own infrastructure as a service (IaaS), which would run on the same underlying physical hardware. Virtual data centers offer an easy on-ramp into cloud-based computing, letting a company quickly set up a complete data center environment without purchasing infrastructure hardware.

質問 # 50
What type of server satisfies workload examples such as ERP, CRM, AI, deep learning and virtualization?
- A. Virtual Machine
- B. dBase
- C. Hypervisor
- D. Bare metal server
正解：D
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 # 51
Write three characteristic of microservices architecture? (Select Three)
- A. All components and functions are in a single instance
- B. Components can be scaled independently of one another
- C. Code can be updated more easily
- D. Teams can use different stacks and different programming languages for different components
正解：B、C、D
解説：
Microservices are an architectural approach in which a single application is composed of many loosely coupled and independently deployable smaller components, or services. Characteristic of microservices : - Code can be updated more easily - new features or functionality can be added without touching the entire application. - Teams can use different stacks and different programming languages for different components. - Components can be scaled independently of one another, reducing the waste and cost associated with having to scale entire applications because a single feature might be facing too much load.
質問 # 52
A Client want to use IBM Cloud for disaster recovery of Vmware environment. They want a low recovery time objective (RTO) and Recovery point objetive (RPO) for workload and, at the same time, only pay for the infrastructure they use. Which option fits their needs ?
- A. VMWare solutions for openShift.
- B. VMWare solution shared
- C. VMWare solutions dedicated
- D. VMWare regulated workloads
正解：B
解説：
IBM Cloud for VMware Solutions Shared uses VMware Cloud Director to enable you to extend your VMs to the cloud with ultimate capacity and scalability, while paying only for what is consumed. With IBM managing the infrastructure up to the hypervisor, you don't need to worry about providing updates and patching, and instead can focus on application innovation. Use Cases : Development and test, Temporary workload migration, Cost-effective disaster recovery. Note : RTO is the maximum amount of time the organization can afford to be without access to the data or application. In other words, how quickly the customer needs to recover the data and application. RPO is the amount of data an organization can afford to lose and effectively dictates how frequently they need to back up their data to avoid losing more.

質問 # 63
Which IBM Cloud service provides virtual servers and bare metal servers with SAN-like iSCSI storage?
- A. IBM File Storage Service
- B. IBM Block Storage Service
- C. IBM Object Storage Service
- D. IBM Backup Storage Service
正解：B
解説：
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.
When data is moved to block storage, the underlying SAN technology breaks the data into separate, uniform-sized pieces, or blocks. Each block will be given a unique identifier. The SAN will then place those blocks onto the physical storage, distributing them across several disks, often making multiple copies.
When a user or application requests data from a block storage system, the underlying SAN technology reassembles the data blocks and presents the data to the user or application.
Block storage decouples data from user environments. It allows data to be spread and duplicated across multiple storage devices, enabling faster retrieval and higher resilience to disk failures.
Benefits:
Provides the lowest latency: Block storage provides the lowest latency for network-based storage versus local disk drives in the server, Provide IOPS up to 48,000 IOPS.
High performing: Block storage is highly available and independent of the clients that access it. It remains available and durable regardless of client outages.
High redundancy: Network-based block storage is considered to have a higher level of redundancy compared to local disk storage.
Endurance and Performance tiers: Block storage has two tiers from which to choose. Volumes can be created from 20 GB to 12 TB in size.
Eight authorized hosts: Block storage allows eight authorized hosts (can request up to 64) to connect via the multipath IO (MPIO) iSCSI connection.
Snapshots: Block storage allows point-in-time non-disruptive "snapshots," which can be replicated to a cross-regional data center as a duplicate volume.
Custom costs: Block storage allows monthly and hourly billing cycles.
Data-at-rest encryption: Block storage offers provider-managed encryption-at-rest. Note: Customer-managed encryption is not supported by IBM Classic Storage; however, customer-managed encryption keys can be stored Use Cases :
As you have learned, block storage has a high performance and is easily updatable. Therefore, many organizations use it for transactional databases.
Because of its high performance and reliability, block storage is a common solution for storing emails.
Block storage suitable for low latency workloads where consistently high speeds required.
