Which of the followings are characteristics of serverless architecture? Except
B
Explanation:
Serverless computing is a cloud computing execution model that provisions computing resources on
demand and offloads all responsibility for common infrastructure management tasks. They are auto-
scalable so it can handle extremely active traffic periods.
Serverless computing does-not means there are no physical servers utilized, of course there are
servers, but we don't have to manage them, in background cloud provider manage (provisioning,
scheduling, scaling, patching and more) for us, this gives developers more time to develop and
optimize their front-end application code and business logic. And with serverless, customers never
pay for idle capacity. They pay only for the resources required to run their applications, and only
when those applications are running.
Serverless is a polyglot environment, enabling developers to code in any language or framework -
Java, Python, node.js - with which they're comfortable. Because serverless scales up and down on
demand in response to workload, it offers significant cost savings for spiky workloads. But it does not
offer the same savings for workloads characterized by predictable, steady or long-running processes;
in these cases, a traditional server environment might be simpler and more cost-effective.
Serverless Implementations differ across service providers, and capabilities vary, including supported
runtimes, authentication, scaling and monitoring.
Serverless architectures are well-suited for event-driven, IOT and stream-processing workloads most
notably open-source Apache Kafka event streaming platform.
Benefits:
- Pay only for the time for our code will run.
- Developer don't have to take care of servers or infrastructure, it maintains by cloud provider, so
they can focus more on development and business logic.
- API Management & Integrated event sources.
- Serverless scales up and down on demand in response to workload

common infrastructure management tasks. They are auto scalable so Its can handle extremely active
traffic periods.
Cloud native development and hybrid cloud strategy are use cases of?
B
Which of the following are use cases of cloud object storage? Except
C
Explanation:
Object Storage enable you to store and access unstructured data anywhere in the world with a self-
service portal backed by RESTful APIs.
Object Storage supports exponential data growth and cloud-native workloads with built-in high-
speed file transfer capabilities, cross-region offerings and integrated services.
Cloud object storage makes it possible to store practically limitless amounts of data, simply and cost
effectively.
Example use cases of cloud object storage include:
- Backup and recovery
- Data archiving
- Cloud-native app data
- AI and analytics
Kubernetes is an open-source container orchestration project that simplifies everything associated
with deploying and managing _____? (Fill the blank)
B
Explanation:
Kubernetes is an open-source container orchestration project that simplifies everything associated
with deploying and managing containers.
Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and
management of containerized applications.
Kubernetes is open source giving you the freedom to take advantage of on-premises, hybrid, or
public cloud infrastructure, letting you effortlessly move workloads to where it matters to you.
Kubernetes Features:
- Automated rollouts and rollbacks
- Storage orchestration
- Self-healing
- Secret and configuration management
Which are following statement are correct for DevOps? Except
B
Explanation:
DevOps does not continuously integrates and automates security throughout the DevOps lifecycle,
Its DevSecOps which continuously integrates and automates security throughout the DevOps
lifecycle.
Remaining three other options are valid for DevOps
Let's understand DevOps first, DevOps is a practice of bringing development and operations teams
together. With DevOps, a developer can automate the build process, code testing and deployment.
DevOps used to deliver code faster to production (Continuous delivery) and iterate continuously
based on market feedback.
With a DevOps strategy you can do the following:
- Accelerate the delivery of reliable software.
- Balance speed, cost, quality, and risk with increased capacity to innovate.
- Reduce time to customer feedback with improved customer experience.
Common use cases for devops include cloud native and mobile applications, application integration,
and modernization and multicloud management.
[Exam Tips]: Remember, DevOps is used to deliver code faster to production, DevOps bring
development and operation team together to deploy code to production faster.
Which of the following are true for IBM Cloud® Databases and IBM Cloud® Database-as-a-Services?
(Select Three)
A, B, C
Explanation:
IBM Cloud® Databases and IBM Cloud® Database-as-a-Services (DBaaS) are fully managed by IBM,
unless customers specifically request to manage some aspects themselves.

True Or False. Content Delivery Network is a distributed server network that delivers temporarily
stored, or cached, copies of website content to users based on the users’ geographical location?
A
Explanation:
Content Delivery Network is a distributed server network that delivers temporarily stored, or cached,
copies of website content to users based on the users’ geographical location to enables faster web
performance. Exam tips: Remember CDN Improving website load times, by distributing content

Which of the following are characteristics of Hybrid Multicloud? (Select Max)
A, B, C
Explanation:
Hybrid multicloud is hybrid cloud that combines public cloud services and private cloud services from
more than one cloud service provider. As It's a combination of public cloud + private cloud so users
have a choice to move workloads between public and private cloud. For example: User can keep
highly sensitive data on private cloud server behind the firewall & and can use public cloud
capabilities also for less-sensitive workloads and data.
An organization want to access to servers and storage devices but does not want to buy them. The
they prefer to have their own employees install and maintain the computing platform and
