A tech startup wants a cloud solution where they can deploy their applications without provisioning the infrastructure. Which cloud service model best fits their needs?
- Function as a Service (FaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
For a tech startup looking for a solution without dealing with infrastructure provisioning, Platform as a Service (PaaS) is ideal. It allows them to focus on application development while the provider handles the underlying infrastructure.
A hospital is migrating its patient data to a cloud provider. They want to ensure that the cloud provider has mechanisms in place to constantly monitor and report any unauthorized access or potential breaches. Which auditing and monitoring practice should they inquire about?
- Disaster Recovery Plans
- Intrusion Detection Systems (IDS)
- Penetration Testing
- Security Information and Event Management (SIEM)
To monitor and report unauthorized access or breaches, hospitals should inquire about Security Information and Event Management (SIEM) systems. SIEM solutions provide real-time analysis of security alerts and event management to ensure the early detection of potential threats.
A company wants to build a serverless application that reacts to changes in their database using Amazon DynamoDB. Which service should they consider for processing these changes?
- AWS Lambda
- Amazon EC2
- Amazon RDS
- Amazon SQS
AWS Lambda is a serverless compute service that can be triggered by changes in Amazon DynamoDB. It allows you to build applications that react to database changes without managing servers.
A healthcare provider needs to move data to the cloud due to an expiring data center lease. They plan to optimize and leverage cloud-native services in the future. Which initial migration strategy might they employ?
- Augmenting with Cloud Services (Hybrid Cloud)
- Lift, Tinker, and Shift
- Refactoring (re-architecting)
- Rehosting (lift-and-shift)
Augmenting with cloud services, often a hybrid cloud approach, would allow the healthcare provider to quickly move data to the cloud while preparing for future optimization and integration with cloud-native services.
During the ________ process, an application might be decomposed and reassembled using cloud-native features for better performance and scalability.
- Rebuilding
- Refactoring
- Rehosting
- Replatforming
The blank should be filled with "Refactoring." Refactoring involves restructuring or optimizing an application for cloud-native features, leading to improved performance and scalability.
Which service allows you to run code in response to events without provisioning or managing servers: AWS Lambda or Azure Virtual Machines?
- AWS Lambda (Option 1)
- Azure Virtual Machines (Option 2)
- Both (Option 3)
- Neither (Option 4)
AWS Lambda allows you to run code in response to events without provisioning or managing servers. Azure Virtual Machines are traditional virtual servers that require provisioning and management.
When discussing the architecture of cloud computing, the application and user interfaces are typically associated with the:
- Back End
- Front End
- Middleware
- Virtualization
In the context of cloud computing, the front end comprises the user and application interfaces, enabling user interaction. This is the "visible" part of cloud systems.
A retail chain is looking to optimize its inventory levels, streamline its procurement processes, and also enhance its customer engagement strategies. How should they integrate ERP and CRM to achieve these goals?
- Integrate ERP and CRM to share customer data for personalized marketing.
- Keep ERP and CRM as separate systems for simplicity.
- Use ERP for customer engagement and CRM for inventory.
- Use ERP for inventory and procurement, and CRM for customer engagement.
Integrating ERP and CRM to share customer data allows personalized marketing and optimizes inventory, procurement, and customer engagement, aligning with the goals.
In which type of virtualization is the entire desktop environment of a computer emulated on a server?
- Desktop Virtualization
- Server Virtualization
- Network Virtualization
- Application Virtualization
The correct option is 'Desktop Virtualization.' In desktop virtualization, the entire desktop environment of a computer is emulated on a server, and users access their desktops remotely. This approach allows for centralized management, security, and the ability to run different operating systems on the same hardware. Server virtualization, on the other hand, involves virtualizing server hardware to run multiple server instances on a single physical server. Network virtualization focuses on virtualizing network resources, while application virtualization virtualizes individual applications for deployment.
The concept of accessing computing resources over the internet is closely related to:
- Client-server architecture
- Cloud computing
- On-premises data centers
- Traditional telephony systems
The concept of accessing computing resources over the internet is closely related to cloud computing, as it's the essence of cloud services. It's distinct from traditional telephony, on-premises data centers, or client-server models.
