What ensures that a cloud service remains operational even if one or more servers fail?

  • Elasticity
  • Fault Tolerance
  • Load Balancing
  • Scalability
'Fault Tolerance' ensures that a cloud service remains operational despite server failures. This typically involves redundant systems or failover mechanisms to maintain service availability.

A company wants to process images uploaded by users to a Google Cloud Storage bucket. The processing should happen immediately after the upload without any manual intervention. Which Google Cloud service would be most appropriate for this?

  • Google Cloud App Engine
  • Google Cloud Functions
  • Google Cloud Storage Triggers (Notifications)
  • Google Kubernetes Engine (GKE)
Google Cloud Storage Triggers (Notifications) can automatically trigger a function when objects are uploaded to a bucket, enabling immediate processing.

AWS's primary service for object storage is:

  • Amazon DynamoDB (NoSQL Database)
  • Amazon EC2 (Elastic Compute Cloud)
  • Amazon RDS (Relational Database Service)
  • Amazon S3 (Simple Storage Service)
Amazon S3 (Simple Storage Service) is AWS's primary service for object storage. It provides scalable, durable, and highly available object storage in the cloud, commonly used for data and file storage.

Paravirtualization differs from full virtualization in that:

  • It doesn't isolate workloads.
  • It doesn't require a hypervisor.
  • It doesn't support live migration.
  • It requires modification of the guest OS.
Paravirtualization requires modifying the guest OS to improve performance, whereas full virtualization does not require such modifications.

In the context of cloud deployment models, which type of cloud typically has a higher upfront cost due to infrastructure investments?

  • Community Cloud
  • Hybrid Cloud
  • Private Cloud
  • Public Cloud
Private Clouds are typically associated with higher upfront costs because organizations need to invest in their infrastructure and management. Public clouds share resources and costs with multiple organizations.

What distinguishes a hybrid cloud from a multi-cloud?

  • Hybrid uses physical servers
  • Mixing public and private clouds
  • Multi-cloud combines different cloud service providers
  • The use of multiple private clouds in a hybrid setup
A hybrid cloud combines public and private cloud infrastructure, whereas a multi-cloud involves using services from different cloud providers, which may not be public-private mix.

The cloud infrastructure that is provisioned for open use by the general public is termed as ________.

  • Community
  • Hybrid
  • Private
  • Public
The cloud infrastructure designed for use by the Public is accessible by individuals, businesses, and organizations. It is hosted and managed by a cloud service provider and offers services on a pay-as-you-go basis. Public clouds are shared resources, providing flexibility and cost-effectiveness.

A multinational corporation is looking for a cloud solution that can be accessed from any of their global locations, without any restrictions on the devices used. Which characteristic of cloud computing best fits their needs?

  • Accessibility
  • Elasticity
  • On-Demand Usage
  • Scalability
Accessibility is a key aspect of cloud computing that ensures that resources are available from anywhere, on any device, making it suitable for global use.

An organization wants to optimize its cloud costs. They decide to focus on analyzing and optimizing their allocated and used cloud resources. Which part of the cloud architecture should they primarily focus on?

  • Cost monitoring tools
  • Reserved instances
  • Resource tagging and categorization
  • Resource utilization analysis
To optimize cloud costs, the organization should focus on analyzing resource utilization and efficiency, identifying underused resources, and rightsizing.

A cloud user received an email claiming to be from the cloud service provider, asking for login details to address a "technical glitch." The user provided the details and later found unauthorized changes in their account. This is an example of how ________ can lead to account hijacking.

  • Denial of Service Attack
  • Phishing Attack
  • Ransomware Attack
  • SQL Injection
This is a classic example of a phishing attack, where attackers deceive users into revealing their credentials, leading to unauthorized access and account hijacking.
