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.
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.
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.
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.
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 is looking to migrate their on-premises SQL Server databases to the cloud. They are already using Microsoft products extensively. Which CSP and specific service would be a natural fit for them?
- Amazon Web Services (AWS) - RDS
- Google Cloud Platform (GCP) - BigQuery
- IBM Cloud - Db2 Warehouse on Cloud
- Microsoft Azure - Azure SQL Database
Microsoft Azure offers Azure SQL Database, a managed SQL database service that seamlessly integrates with Microsoft products, making it a natural fit.
When an organization opts for a cloud service where they only need to manage and configure the operating system, it is referred to as ________.
- Database as a Service (DBaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Infrastructure as a Service (IaaS) provides users with virtualized infrastructure components. Organizations manage and configure the operating system, applications, and data on top of this infrastructure while leaving hardware management to the cloud provider.
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.
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.
________ is a strategy where applications are moved to the cloud in their existing form, with the intention of making modifications at a later stage.
- Re-architecting
- Re-factoring
- Re-hosting
- Re-platforming
In the "re-hosting" strategy, applications are migrated as-is to the cloud, with modifications planned for a later phase.
CRM software primarily focuses on:
- Document Editing
- Financial Accounting
- Managing Customer Relationships
- Video Editing
Customer Relationship Management (CRM) software primarily focuses on managing and improving interactions and relationships with customers.
Storage virtualization involves:
- Abstracting physical storage
- Emulating hardware
- Enhancing software performance
- Running multiple OSes
Storage virtualization abstracts physical storage devices to create a logical pool, simplifying management and improving utilization.
