In a microservices architecture, the pattern that isolates failures and ensures that a failure in one service doesn't impact others is called the ________ pattern.

  • Adapter
  • Circuit Breaker
  • Observer
  • Singleton
The Circuit Breaker pattern is used to isolate failures in a microservices architecture. It prevents a single service failure from cascading through the system.

Continuous monitoring in cloud environments is essential for:

  • Detecting and mitigating threats
  • Ensuring high availability of services
  • Monitoring competitors' cloud usage
  • Reducing cloud infrastructure costs
Continuous monitoring in the cloud is crucial for detecting and mitigating security threats, ensuring data protection, and maintaining compliance with regulations. It's not primarily about cost reduction or monitoring competitors.

Google Cloud Functions can be triggered by events from which of the following Google Cloud services?

  • Google Cloud Bigtable
  • Google Cloud Compute Engine
  • Google Cloud Pub/Sub
  • Google Cloud Storage
Google Cloud Functions can be triggered by events from Google Cloud Pub/Sub, making it easy to build event-driven applications.

In terms of data analytics, what advantage does AWS Redshift provide over traditional databases?

  • ACID Compliance and High Throughput
  • Columnar Storage and Parallel Processing
  • Document Store and Strong Consistency
  • Graph Database and Horizontal Scaling
AWS Redshift is designed for data warehousing and analytics, offering columnar storage and parallel processing for improved performance.

In a scenario where there's a tight deadline to exit a data center, which migration approach might be prioritized, even if it doesn't yield immediate cloud optimization benefits?

  • Rearchitect (rebuild)
  • Refactor (re-architect)
  • Rehost (lift and shift)
  • Repurchase (buy a new one)
When facing a tight deadline to exit a data center, 'Rehost' (lift and shift) might be prioritized, even if it doesn't yield immediate cloud optimization benefits, as it's the quickest and least disruptive approach.

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
