1. What is the primary function of a cloud load balancer?
A. To encrypt sensitive cloud data
B. To distribute network traffic across multiple servers
C. To store backup data
D. To monitor cloud infrastructure performance
Answer: b) To distribute network traffic across multiple servers
Rationale: A cloud load balancer ensures that incoming traffic is evenly distributed
across multiple servers, improving performance, availability, and reliability.
2. Which of the following is an example of a PaaS offering?
A. AWS EC2
B. Microsoft Azure App Services
C. Dropbox
D. IBM Watson
Answer: b) Microsoft Azure App Services
,Rationale: Microsoft Azure App Services is a Platform as a Service (PaaS) offering
that allows developers to build and host applications in the cloud without
managing the underlying infrastructure.
3. What is the benefit of "auto-scaling" in cloud computing?
A. It allows businesses to scale up or down their cloud usage automatically based
on demand
B. It enables manual control over cloud resources
C. It restricts the amount of cloud resources available
D. It improves network latency
Answer: a) It allows businesses to scale up or down their cloud usage
automatically based on demand
Rationale: Auto-scaling adjusts the amount of computing resources automatically
based on demand, ensuring efficient use of resources and cost savings.
4. Which of the following is an example of IaaS?
A. Google App Engine
B. Amazon EC2
C. Salesforce CRM
,D. Office 365
Answer: b) Amazon EC2
Rationale: Amazon EC2 provides virtualized computing resources on-demand,
which is a classic example of IaaS.
5. Which of the following is a disadvantage of Cloud Computing?
A. High up-front cost
B. Dependence on internet connectivity
C. Limited scalability
D. Lack of flexibility
Answer: b) Dependence on internet connectivity
Rationale: Cloud computing relies on an internet connection, and without it, users
may not be able to access their data or services.
6. Which of the following best describes "elastic load balancing"?
A. A mechanism that scales computing resources according to user demand
B. A process of monitoring servers for load
C. A service for balancing resource allocation in a hybrid cloud
, D. A tool that analyzes traffic patterns in the cloud
Answer: a) A mechanism that scales computing resources according to user
demand
Rationale: Elastic load balancing automatically adjusts computing resources based
on traffic demand, ensuring optimal performance.
7. What does the concept of “elasticity” in cloud computing refer to?
A. The ability to rapidly increase or decrease computing resources
B. The physical size of cloud servers
C. The dependency on local storage
D. The use of hardware accelerators
Answer: a) The ability to rapidly increase or decrease computing resources
Rationale: Elasticity in cloud computing allows users to quickly scale resources up
or down based on demand, which helps optimize costs and performance.
8. In Cloud Computing, what is the role of an API (Application Programming
Interface)?
A. Manage hardware resources
A. To encrypt sensitive cloud data
B. To distribute network traffic across multiple servers
C. To store backup data
D. To monitor cloud infrastructure performance
Answer: b) To distribute network traffic across multiple servers
Rationale: A cloud load balancer ensures that incoming traffic is evenly distributed
across multiple servers, improving performance, availability, and reliability.
