A key advantage of SaaS is the elimination of the need for individual ________ and maintenance.
- Data Centers
- Installation
- Licensing
- Servers
SaaS eliminates the need for individual servers and maintenance. Users don't have to worry about the physical infrastructure, as it's managed by the SaaS provider.
The ________ is a platform provided by AWS specifically tailored for IoT devices.
- AWS EC2
- AWS IoT Core
- AWS Lambda
- AWS S3
AWS IoT Core is a managed cloud service designed to connect IoT devices to the cloud, making it suitable for IoT applications. It provides features for device communication, security, and data management.
When considering cold starts in Google Cloud Functions, which runtime generally has the fastest initialization time?
- Go
- Java
- Node.js
- Python
In Google Cloud Functions, Go generally has the fastest cold start initialization time due to its efficient runtime. This is important for minimizing latency.
The ________ is a set of security standards designed to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment.
- FERPA
- HIPAA
- PCI DSS
- SOX
PCI DSS (Payment Card Industry Data Security Standard) is a comprehensive set of security standards designed to protect credit card information and ensure that companies maintain a secure environment when handling such data.
The primary role of the back end in a cloud computing environment is to:
- Handle user authentication
- Host user interfaces
- Manage server hardware
- Manage servers
The back end in cloud computing is responsible for managing servers, handling data, and executing the core functionalities of the application. It's the "invisible" part.
Google Cloud's equivalent to AWS's RDS (Relational Database Service) is ________.
- Bigtable
- CloudSQL
- Datastore
- Firestore
Google Cloud's counterpart to AWS RDS is CloudSQL, which offers managed relational databases like MySQL and PostgreSQL.
Which of the following best describes cloud computing?
- A way to store personal photos and videos
- A method for companies to save on IT operational costs
- A system to play online games
- Delivering computing services over the internet
Cloud computing is about delivering various computing services like storage, databases, servers, networking, software, and more over the internet. While some of the other options may be components or uses of cloud computing, the core idea is the delivery of computing services via the internet.
A company has a legacy application that is tightly coupled with its current database. They want to migrate to the cloud and modernize the application for better scalability and performance. Which migration strategy should they consider?
- Rearchitecting (rebuilding)
- Refactoring (re-architecting)
- Rehosting (lift-and-shift)
- Retiring or Decommissioning
Refactoring, or re-architecting, is the most suitable strategy when migrating to the cloud while modernizing an application. It involves making application changes to optimize for the cloud environment, ensuring scalability and performance.
When deploying AI services in the cloud, what is the significance of edge computing, especially concerning IoT devices?
- Enhanced cloud scalability
- Improved model complexity
- Increased cloud cost
- Reduced latency
Edge computing significantly reduces latency for AI services in IoT. Processing data closer to the source (IoT device) minimizes the time it takes for results, critical in real-time applications.
How does AWS Lambda handle concurrency and scaling when there are multiple invocations?
- Automatic Scaling
- Connection Pools and Queues
- Manual Scaling and Capacity Planning
- Throttling and Rate Limiting
AWS Lambda automatically handles concurrency and scaling. It dynamically allocates resources to accommodate multiple invocations, ensuring that the desired number of simultaneous executions are maintained.
