Mod 11 Cloud and Virtualization Security

Which of the following statements most accurately describes characteristics of cloud computing? Select two.

• They reduce the cost of CapEx by shifting them to OpEx.

• It provides peace of mind knowing exactly where your data resides.

• Computing resources can be increased or decreased quickly to meet changing demands.

• Increasing computing resources require minimal human interaction from service providers.

Answer explanation

Cloud computing reduces CapEx by converting it to OpEx, allowing for more flexible budgeting. Additionally, it enables rapid scaling of resources to adapt to changing demands, a key characteristic of cloud services.

A potential client wants to migrate some of their services to the cloud but is concerned about failover capabilities. What will the sales engineer from the cloud provider most likely say to help ease the client's concern?

• The cloud company will reserve additional computing resources for immediate availability.

• The client can pay a little extra every month to ensure excess capacity can be provisioned.

• If there is a server failure, the client will be immediately contacted for further instructions.

• If there is a server failure, services will be moved to other servers at no additional cost.

Answer explanation

The correct choice reassures the client that in the event of a server failure, their services will be seamlessly transferred to other servers without incurring extra costs, enhancing their confidence in the cloud's failover capabilities.

You are a cloud sales engineer working with an institution that needs to comply with strict federal regulations to avoid being levied very hefty fines. What type of cloud offering are you most likely to recommend?

• A public cloud

• A hybrid cloud

• A private cloud

• A community cloud

Answer explanation

A community cloud is ideal for institutions with strict federal regulations, as it allows multiple organizations with similar compliance needs to share resources while maintaining security and regulatory standards.

Diana is not very tech savvy but is a marketing genius. She signs a deal with a cloud contractor who will help her set up an online retail store selling rare items. On what type of cloud will her website most likely be hosted?

• A public cloud because the cloud services are available to everyone.

• A hybrid cloud because some elements need a higher degree of security.

• A private cloud to ensure all transactions use encryption and secure authentication.

• A community cloud because the rare items she sells have an exclusive community of followers.

Answer explanation

Diana's online retail store will likely be hosted on a public cloud, as it provides accessible services to everyone, making it ideal for her to reach a broad audience for selling rare items.

Your company asks you to be the project lead in establishing a private cloud. Which of the following are most likely to be true? Select two.

• You will create a private network and isolate it from all the available cloud service providers.

• You expect your company to purchase and maintain all the required hardware and software.

• You will use proprietary software on dedicated servers and storage from a cloud provider.

• You will create a network with no connectivity to ensure a high degree of privacy and security.

• You will use a cloud provider with tight integration to ensure outside entities cannot connect.

Answer explanation

Creating a private cloud involves establishing a private network and requiring the company to purchase and maintain all necessary hardware and software, ensuring control and security over the infrastructure.

An industrial plant has a series of Internet of Things devices that connect to a nearby wireless system. The system will process the collected data, store it, and send it off to the cloud. From a computing location perspective, what type of model is assumed in this scenario?

• Fog

• Edge

• Hybrid

Answer explanation

The scenario describes a Fog computing model, where data processing occurs closer to the IoT devices (at the fog layer) before sending it to the cloud, enhancing efficiency and reducing latency.

This scenario relates to computing that is performed at or very near to the source of data (edge) instead of relying on the cloud or on-premises for processing. What type of computing is this?

• On-premises

• Edge

• Cloud

• Off-premises

Answer explanation

The correct answer is 'Edge' computing, which processes data close to its source, reducing latency and bandwidth use, unlike cloud or on-premises computing that relies on centralized data centers.

A programming hobbyist uses a cloud provider to create an online app to back up his CD collection. As soon as he launches the app, it creates an online backup in the form of an ISO image, creates separate MP3 files for each song, and downloads them to a specific folder. What type of computing does this most likely resemble?

• On-premises

• Edge

• Cloud

• Fog

• Off-premises

Answer explanation

The app uses a cloud provider to create backups and store data online, which aligns with cloud computing. This model allows for scalable resources and remote access, distinguishing it from on-premises or edge computing.

A company is using resources on a server to host an application in a Software as a Service (SaaS) environment. Which of the following best describes the type of architecture being employed?

• Serverless infrastructure

• Transit gateway

• Thick client

• Thin client

• SWG

Answer explanation

Serverless infrastructure allows companies to host applications without managing servers, making it ideal for SaaS environments. This architecture automatically scales resources based on demand, aligning with the described scenario.

Various departments in a large organization have been using computing and storage resources from AWS in an uncoordinated fashion. To manage their cloud resources more efficiently, they would like to adopt an approach that is more consolidated and streamlined. Which of the following would you recommend?

• Cloud-native microservices

• Transit gateway

• Direct-connect portal

• Secure web gateway

Answer explanation

A Transit Gateway allows for centralized management of multiple VPCs and on-premises networks, streamlining resource connectivity and reducing complexity, making it the best choice for consolidating cloud resources in a large organization.
