Cloud Computing Basics
Q1. What is the primary benefit to a Google Cloud customer of using resources in several zones within a region?
For expanding services to customers in new areas
For better performance
For getting discounts on other zones
For improved fault tolerance
Using multiple zones within a region helps protect applications
from failures affecting a single zone, improving availability.
Q2. What type of cloud computing service lets you bind your application code to libraries that give access to the infrastructure your application needs?
Software as a service
Infrastructure as a service
Platform as a service
Virtualized data centers
Hybrid cloud
Platform as a Service provides managed runtimes and libraries
that allow developers to focus on application logic.
Q3. Why might a Google Cloud customer use resources in several regions around the world?
To bring their applications closer to users around the world, and for improved fault tolerance
To offer localized application versions in different regions.
To improve security
To earn discounts
Multi-region deployments reduce latency for global users
and protect against large-scale regional outages.
Cloud Computing Services
Q1. Does a cloud computing service let you scale your resource use up and down?
Yes
No
Elasticity is a core feature of cloud computing,
allowing resources to scale based on demand.
Q2. To get resources from a cloud computing provider, is working with a person at the provider required?
Yes
No
Cloud services are provisioned through self-service portals and APIs,
without human interaction.
GCP Regions and Zones
Q1. Why might a GCP customer use resources in several zones within a region?
For improved fault tolerance
For better performance
Multiple zones protect applications from failures
affecting a single zone.
Q2. Why might a GCP customer use resources in several regions around the world?
To bring their applications closer to users around the world, and for improved fault tolerance
To improve security
Using multiple regions reduces latency and increases resilience
against regional outages.
Introducing Google Cloud Platform
Q1. Choose fundamental characteristics of cloud computing.
Customers pay only for what they use, resources are on-demand and self-service,
accessible over the network, and can scale up and down
Providers always dedicate physical resources and require long-term contracts
All resources are open-source-based
Cloud computing is defined by elasticity, on-demand self-service,
network access, and usage-based billing.
Q2. Choose a fundamental characteristic of devices in a virtualized data center.
They are manageable separately from the underlying hardware.
They are more secure.
They are available from anywhere on the Internet.
They use less resources than devices in a physical data center.
Virtualization decouples devices from physical hardware,
enabling independent management.
Q3. What type of cloud computing service lets you bind your application code to libraries that give access to the infrastructure your application needs?
Platform as a Service
Infrastructure as a Service
Software as a Service
Hybrid cloud
Virtualized data centers
PaaS provides application frameworks and libraries
while abstracting infrastructure management.
Q4. What type of cloud computing service provides raw compute, storage, and network?
Software as a Service
Database as a Service
Platform as a Service
Infrastructure as a Service
Infrastructure as a Service delivers fundamental
building blocks similar to physical data centers.
Q5. Which statement is true about the zones within a region?
The zones within a region are never closer than 160 km.
Each zone corresponds to a single physical data center.
Customers must choose exactly one zone per region.
The zones within a region have fast network connectivity among them.
Zones in the same region are connected by high-speed networks,
enabling low-latency communication.
Q6. What kind of customer benefits most from billing by the second for cloud resources such as virtual machines?
Customers who create and run many virtual machines
Customers who create many virtual machines and leave them running for months
Customers who create too few virtual machines to get discounts
Customers who create virtual machines running commercially licensed operating systems
Per-second billing benefits workloads with frequent start
and stop cycles by reducing wasted compute time.
