98-369 Microsoft Cloud Fundamentals Chapter 1: Understanding the Cloud - 2

Which of the following is not a benefit of cloud computing? (Choose all that apply) a. Improved resilience and agility b. Server consolidation c. Better control d. Reduced operational costs

Better control Explanation: Cloud computing offers several benefits, including Improved resilience and agility, server consolidation, reduced operational costs, and more. It does not offer better control.

Which funding model should be used to pay for several servers? a. CapEx b. Subscription c. Pay as you go d. OpEx

CapEx Explanation: Capital Expenditures (CapEx) are funds used by an organization to acquire or upgrade physical assets such as servers, networking equipment, and storage. It also includes real estate such as buildings or data center space

Which type of cloud is delivered on a physical infrastructure that is used by a single organization? a. Hybrid cloud b. Shared public cloud c. Floating public cloud d. Dedicated public cloud

Dedicated public cloud Explanation: The dedicated public cloud is similar to the shared public cloud, but the cloud is delivered on a dedicated physical infrastructure. While cost might be higher than that of the shared public cloud, the dedicated public cloud might offer better security, performance, and customization.

Which of the following allows you to change the cloud resources based on the required workload? a. Scalability b. Availability c. Elasticity d. Redundancy

Elasticity Explanation: Elasticity is the degree in which a system can adapt to workload changes by provisioning or deprovisioning resources automatically. Of course, elastic computing is the dynamic provisioning and deprovisioning of computer resources to meet the varying workload. By offering elasticity, you can increase and decrease cost, quality, and resources.

Describe the term "high availability"

High availability is the combination of technology, protocols, and redundant hardware that ensures a certain degree of operational continuity during a given measurement period while resisting disaster and failure.

The __________________ service model provides the hardware for servers, storage, and networking—usually in the form of a standardized virtual server environment.

Infrastructure as a Service (IaaS) Explanation: The Infrastructure as a Service (IaaS) service model provides the hardware for servers, storage, and networking—usually in the form of a standardized virtual server environment—and provides a foundation for PaaS and SaaS. The organization manages the guest operating system, the software, and the database application/servers. Cost is based on an agreed service level.

____________ allows several companies to use the same cloud products.

Multi-tenancy Explanation: Multi-tenancy allows several companies to use the same cloud products. For example, for an application, multi-tenancy means that different customers can use the same codebase. However, to keep customers separated from other customers, their configuration and data are stored in separate containers.

Which cloud service should be used to run an application that is accessed using a web browser? a. SaaS b. IaaS c. NaaS d. PaaS

PaaS Explanation: Platform as a Service (PaaS) allows you to buy, develop, test, deploy, and manage software applications so that users can access the applications.

Which type of cloud service is Office 365? a. Storage services B. Communications services c. Productivity services d. Search services

Productivity services Explanation: Productivity services allows users to work and collaborate. An example of productivity services is Office 365, which allows users to create and share documents.

Which type of cloud service is provided by Office 365? a. PaaS b. IaaS c. NaaS d. SaaS

SaaS Explanation: Software as a Service (SaaS) is the most basic form of cloud computing. It provides software and associated data (such as databases or user documents) that is hosted on the cloud. It is typically accessed by an application (such as a web browser) over the Internet.

Describe the term "scalability"

Scalability is the ability of a computer application or product to continue to function as the application or product changes in size or volume in order to meet user need.

To protect an application running on the cloud that is accessible using a web browser, you should use __________ to encrypt data that is sent over the network.

Secure Socket Layer (SSL) Explanation: Secure Socket Layer (SSL) uses a cryptographic system that uses two keys to encrypt data: a public key known to everyone and a private or secret key known only to the recipient of the message. The public key is published in a digital certificate, which also confirms the identity of the web server.

If you want to monitor your cloud applications from multiple locations, you should use the ___________________.

System Center Global Service Monitor Explanation: System Center Global Service Monitor is a cloud service that extends the capabilities of System Center 2012 R2/2016 by monitoring external web-based applications from multiple locations around the world. It is designed to show you what the customer experiences when running your web applications.

____________ deals with honesty, openness, and accountability when using the cloud.

Transparency Explanation: Transparency deals with honesty, openness, and accountability. You must know how individual virtual machines are segregated from other tenant virtual machines.

Describe the term "Virtual Private Networking"

Virtual Private Networking is technology that uses encrypted tunnels to create secure connections across public networks like the Internet.

When using public-key cryptography to deploy digital certificates, you are using _____________ keys.

asymmetric Explanation: Asymmetric key, also known as public-key cryptography, uses two mathematically related keys. One key is used to encrypt the data and the second key is used to decrypt the data.

The _______________ provides services accessible from the Internet, such as a network application or server.

cloud Explanation: The cloud is a network of servers, and each server in the network has a different function. Some servers run applications or deliver a service. By using the cloud, you don't have to have the individual application or services running on the user's computers.

The ____________ is provided by a third-party company that is accessible only by users within a specific organization.

hosted private cloud Explanation: A hosted private cloud is provided by a third-party company but is accessible only by users within a specific organization. In other words, the resources are leased or owned by the organization but are managed and located away from the organization.

You want to deploy an application to the cloud but you want to ensure that the actual data is stored in-house. Which type of cloud should be used? a. dedicated public cloud b. private cloud c. hosted private cloud d. hybrid cloud

hybrid cloud Explanation: A hybrid cloud is a cloud-computing environment in which the organization provides and manages some of the resources in-house and a third party provides the hosted servers for the organization externally. In other words, it utilizes both a public cloud and a private cloud.

The subscription funding model is the same as ____________.

pay-as- you-go Explanation: The subscription or pay-as- you-go model is a computing billing method that is aimed at organizations and end-users. The organization or user is billed for the services used, typically on a recurring basis.

The _________ between your corporation and the cloud provider will specify the level of availability for the provided services or services.

service-level agreement (SLA) Explanation: When designing servers and the services they provide, they are often assigned service-level agreements (SLAs), which state the level of availability those servers or services must maintain.
