ICC Cloud Computing & Services 2 — Questions and Answers
Question 1: Which cloud deployment model hosts infrastructure exclusively for a single organization, either on-premises or by a third party?
- Public cloud
- Hybrid cloud
- Private cloud (Correct answer)
- Community cloud
Correct answer: Private cloud
A private cloud is dedicated to one organization, providing greater control and security over resources.
Question 2: In Informatica Cloud (IICS), what is the role of the Secure Agent?
- Hosts the cloud repository metadata
- Executes tasks locally and communicates with the cloud service (Correct answer)
- Manages user authentication for the platform
- Provides a web UI for designing mappings
Correct answer: Executes tasks locally and communicates with the cloud service
The Secure Agent runs on-premises or in a private cloud and executes data integration tasks while communicating securely with Informatica Intelligent Cloud Services.
Question 3: Which cloud service model gives users the most control over the operating system and middleware?
- SaaS
- PaaS
- IaaS (Correct answer)
- FaaS
Correct answer: IaaS
IaaS (Infrastructure as a Service) provides virtualized computing resources, giving users full control over OS, middleware, and runtime.
Question 4: What does 'elasticity' mean in the context of cloud computing?
- The ability to encrypt data at rest
- The automatic scaling of resources up or down based on demand (Correct answer)
- The redundancy of data across multiple regions
- The latency reduction via edge nodes
Correct answer: The automatic scaling of resources up or down based on demand
Elasticity refers to the cloud's ability to dynamically provision and deprovision resources in response to workload changes.
Question 5: In IICS, which connection property is required when configuring a Salesforce connection?
- JDBC URL
- Security token (Correct answer)
- SSH key path
- Kerberos principal
Correct answer: Security token
Salesforce requires a security token (appended to the password) in addition to credentials when connecting from external tools like IICS.
Question 6: Which cloud characteristic ensures that multiple customers share the same physical infrastructure while keeping their data isolated?
- Broad network access
- Resource pooling (Correct answer)
- Measured service
- Rapid elasticity
Correct answer: Resource pooling
Resource pooling allows a provider to serve multiple tenants from shared physical resources while maintaining logical isolation between them.
Question 7: What is the primary purpose of a cloud data lake in a modern data architecture?
- To enforce ACID transactions on structured data
- To store raw, unprocessed data in its native format at scale (Correct answer)
- To replace relational databases for OLTP workloads
- To cache frequently accessed report data
Correct answer: To store raw, unprocessed data in its native format at scale
A data lake stores vast amounts of raw data in its native format until it is needed for analysis, without requiring upfront schema definition.
