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.
A startup is developing a chatbot that should respond within milliseconds. They want to use a Google Cloud service that can execute code without the overhead of server management and with minimal cold start times. What would you recommend?
- Google Cloud App Engine
- Google Cloud Compute Engine
- Google Cloud Functions
- Google Cloud Run
Google Cloud Run offers serverless execution of containerized applications, providing fast response times with minimal cold starts.
One of the event sources that can trigger a Google Cloud Function is ________.
- File Upload
- Pub/Sub
- REST API
- SSH Connection
An event source like Google Cloud Pub/Sub can trigger a Google Cloud Function when new messages are published to a topic.
Cloud computing is primarily about:
- Building physical data centers
- Buying new computers for the organization
- Making use of quantum computing
- The shift from traditional software models to the internet
The essence of cloud computing is the transition from conventional software models and hardware reliance to utilizing the power of the internet for many computing needs. It's not specifically about buying hardware or building physical infrastructures.
You are the cloud security officer of a company. An employee reports suspicious activity in their cloud account, like unfamiliar files and settings. What is the most likely security concern you should investigate?
- Account Compromise
- Cloud Outage
- Data Leakage
- Unauthorized Access
Suspicious activity in an employee's account with unfamiliar files and settings suggests an account compromise, indicating that someone unauthorized may have accessed the account.
When optimizing costs for cloud services, what does the term "Right-sizing" refer to?
- Automatically managing resources to save costs
- Matching resource requirements to workload demands
- Reducing security risks
- Scaling horizontally
"Right-sizing" means matching the resources (e.g., CPU, memory) to the workload's actual demands, preventing over-provisioning and unnecessary costs.
Which term describes the combination of the software and hardware that a user interacts with in a cloud service?
- Client Environment
- Cloud Interface
- Service Endpoint
- User Experience
The "Cloud Interface" encompasses the software and hardware components that a user interacts with when using a cloud service, including web applications and APIs.
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.
