NEW QUESTION # 161
What is virtualization?

A. Allows multiple virtual machines to run on a single physical host
B. Uses hardware to create an abstraction layer over software
C. Allows a virtual machine to run on a physical host
D. Seeing into the future

Answer: A

Explanation:
Virtualization is a process that allows for more efficient utilization of physical computer hardware and is the foundation of cloud computing. Virtualization uses software to create an abstraction layer over computer hardware that allows the hardware elements of a single computer-processors, memory, storage and more-to be divided into multiple virtual computers, commonly called virtual machines (VMs). Each VM runs its own operating system (OS) and behaves like an independent computer, even though it is running on just a portion of the actual underlying computer hardware. Benefit of virtualization: Virtualization brings several benefits to data center operators and service providers: Resource efficiency: Before virtualization, each application server required its own dedicated physical CPU-IT staff would purchase and configure a separate server for each application they wanted to run. (IT preferred one application and one operating system (OS) per computer for reliability reasons.) Invariably, each physical server would be underused. In contrast, server virtualization lets you run several applications-each on its own VM with its own OS-on a single physical computer (typically an x86 server) without sacrificing reliability. This enables maximum utilization of the physical hardware's computing capacity. Easier management: Replacing physical computers with software-defined VMs makes it easier to use and manage policies written in software. This allows you to create automated IT service management workflows. For example, automated deployment and configuration tools enable administrators to define collections of virtual machines and applications as services, in software templates. This means that they can install those services repeatedly and consistently without cumbersome, time-consuming. and error-prone manual setup. Admins can use virtualization security policies to mandate certain security configurations based on the role of the virtual machine. Policies can even increase resource efficiency by retiring unused virtual machines to save on space and computing power. Minimal downtime: OS and application crashes can cause downtime and disrupt user productivity. Admins can run multiple redundant virtual machines alongside each other and failover between them when problems arise. Running multiple redundant physical servers is more expensive. Faster provisioning: Buying, installing, and configuring hardware for each application is time-consuming. Provided that the hardware is already in place, provisioning virtual machines to run all your applications is significantly faster. You can even automate it using management software and build it into existing workflows. [Exam Tips]: You can expect few questions from Virtualization and benefits of virtualization.

NEW QUESTION # 162
Which service on IBM Cloud is offered as a document oriented database ?

A. Enterprise DB
B. Mongo DB
C. MySql
D. Db2

Answer: B

Explanation:
MongoDB is a cross-platform document-oriented database.

NEW QUESTION # 163
Which of the following are types of Key Value Database?(Select Two)

A. MongoDB
B. PostgreSQL
C. Redis
D. etcd

Answer: C,D

Explanation:
etcd is an open source distributed key-value store used to hold and manage the critical information that distributed systems need to keep running. etcd's performance is heavily dependent upon storage disk speed, so it's highly recommended to use SSDs in etcd environments. Redis (for REmote DIctionary Server) is an open-source, in-memory, NoSQL key-value store that is used primarily as an application cache or quick-response database. Redis supports multiple data structures, built-in Lua scripting, multiple levels of on-disk persistence, and high availability. Redis is an in-memory data store and can function as a database, cache, or message broker. In-Correct Answers : MongoDB is an open source, non-relational database management system that uses flexible documents to process and store various forms of data. A NoSQL solution, MongoDB provides an elastic data model that enables users to store and query multivariate data types with ease. This not only simplifies database management for developers but also creates a highly scalable environment for applications and services. MongoDB uses documents or collections of documents as its basic unit of data. Formatted as JSON objects, these documents can store various types of data and be distributed across multiple systems. MongoDB offers a few capabilities that make it stand out from other database management systems, including load balancing, ad hoc database queries, and multi-language support. PostgreSQL, commonly pronounced "Post-GRES," is an open-source database that has a strong reputation for its reliability, flexibility, and support of open technical standards. PostgreSQL provides the ability to restore databases to a specific moment in time because it maintains a write-ahead log that logs every database change. PostgreSQL features built-in support for multiple procedural languages.
