Upgrading and patching is essential for maintaining the security and stability of the cloud
infrastructure. Upgrading involves updating software to the latest version, which often
includes bug fixes, security patches, and new features. Patching refers to the process of
fixing bugs and vulnerabilities in software to prevent cyber attacks. Templates are
predefined configurations that can be used to create multiple resources. They can be
used to create virtual machines, storage accounts, and other resources. Orchestration
helps in automating the deployment of infrastructure and resources. Automation helps in
automating manual tasks but is not a process specific to updating a system.
David wants to ensure that the company's cloud-based solutions are not tied to a single
cloud provider and can easily switch between providers based on business needs. He
needs to develop a strategy that allows for cloud provider flexibility while minimizing the
risk of losing data and functionality. Which of the following risk management concepts
should they utilize to ensure that the company's cloud-based solutions can switch
between providers while minimizing risk? - Correct Answer Data Portability
Explanation
Data Portability is the most appropriate risk management concept for ensuring cloud
provider flexibility while minimizing risk. It refers to the ability to move data from one cloud
provider to another without experiencing significant downtime or loss of data. Developing
a strategy that enables data portability ensures that the company's data is easily
transferable between different cloud providers, which is crucial for business continuity and
flexibility. A risk register is a document or database used to track and manage identified
risks, including their status, severity, and associated risk response strategies. Findings
refer to the results or outcomes of a risk assessment, which may include identified risks,
vulnerabilities, and potential impact on the organization. Vendor lock-in is the situation
where an organization becomes dependent on a specific vendor's products, services, or
technologies, making it difficult or costly to switch to another vendor or solution.

software vendors and make informed decisions to optimize licensing expenditure.
Content Delivery Network is incorrect because it is a distributed network of servers that
cache and serve content to end-users based on their geographic location, improving
website performance and reducing latency. It allows organizations to bid on unused EC2
instances, offering savings of up to 90% compared to On-Demand pricing. Maintenance
refers to the costs incurred for ongoing support and maintenance of the cloud resources.
David, a cybersecurity analyst at Kelly Infotech Innovators, wants to assess the security of
their cloud infrastructure. He wants to conduct an authorized simulated attack to identify
any vulnerabilities and suggest remediation actions. Which of the following is the most
appropriate security assessment technique for David to use in this scenario? - Correct
Answer Penetration
Explanation
The purpose of penetration testing is to identify vulnerabilities before an attacker can
exploit them, and to provide remediation or mitigation suggestions to improve security. In
this scenario, they want to conduct an authorized simulated attack on the cloud
infrastructure, which makes penetration testing the most appropriate technique to use.
Web Application Scanning is a technique that connects to web applications and searches
for vulnerabilities. Vulnerability scanning is a technique that checks systems for common
misconfigurations and security flaws. Hardening is a technique that reduces
vulnerabilities and risks by applying best practices, configurations, and tools to systems.
Which of the following is defined as a solution where customers pay for and use software
on an as-needed basis - Correct Answer Subscription Services
Explanation
Subscription Services is a type of cloud computing model where customers pay for and
use software on an as-needed basis, rather than purchasing and installing the software on
their own machines. This solution provides cost savings, scalability, and flexibility for the
customer, as they can easily scale up or down as needed, without having to invest in
expensive hardware or software licenses upfront. It also allows the customer to access
the latest updates and features of the software without the need for manual upgrades.
This model is commonly used for Software as a Service (SaaS) solutions, where the
customer accesses the software through a web browser or application. Feasibility Study is
,an evaluation of the practicality of a proposed project or system, taking into account its
economic, technical, and social feasibility. Machine learning is a subset of artificial
intelligence that involves training computers to learn from data, without being explicitly
programmed. Cloud Collaboration is a service delivery model that enables multiple users
to work together and share resources and data over the internet.
Which of the following is defined as a process of breaking down a monolithic application
into smaller, independent services that can be deployed and scaled independently? -
Correct Answer Microservices
Explanation
Microservices is a software development methodology that breaks down a monolithic
application into smaller, independent services that can be deployed and scaled
independently. This process is called decomposition. Microservices are independent of
each other and communicate with each other through application programming interfaces
(APIs). Each service is designed to perform a specific function, such as authentication,
payment processing, or order fulfillment. Microservices architecture provides a more
flexible and scalable approach to application development, deployment, and
maintenance. It allows organizations to build and deploy applications faster, more
efficiently, and at a lower cost. Big data refers to extremely large and complex data sets
that cannot be processed using traditional data processing tools. It involves using
advanced analytical techniques and technologies to analyze, process, and extract
insights from large volumes of data, often in real-time. Containerization is a process of
packaging and deploying applications in a portable and isolated environment, which
allows for easy management and deployment of applications across multiple
environments. Machine learning is a subset of artificial intelligence that involves training
computers to learn from data, without being explicitly programmed. It involves developing
algorithms and statistical models that allow computers to improve their performance on a
specific task based on experience.
Which of the following cloud deployment models allows an organization to utilize
computing resources from both a public and a private cloud environment? - Correct
Answer Hybrid
Explanation
A hybrid cloud deployment model is a type of cloud environment that allows an
organization to utilize computing resources from both a public and a private cloud
environment. This allows organizations to take advantage of the scalability and cost-
effectiveness of the public cloud for non-sensitive workloads while still maintaining control
and security over sensitive data and applications through the private cloud. PaaS
(Platform-as-a-Service) provides a platform for developers to build and deploy
, applications without worrying about the underlying infrastructure. This is not a cloud
deployment model. Public cloud deployment involves sharing computing resources with
multiple customers over the internet. It offers cost-effectiveness, scalability, and flexibility,
making it an excellent choice for organizations that want to reduce their IT costs, scale
their computing resources as needed, and focus on their core business activities.
However, public clouds may not provide the necessary level of control, customization, and
security required by organizations that deal with sensitive data or have specific regulatory
requirements. Private cloud deployment involves building and maintaining a cloud
infrastructure that is exclusively for a single organization. It provides more control,
customization, and security than public clouds, making it a good fit for organizations that
deal with sensitive data, have specific regulatory requirements, or need to meet strict
service level agreements. However, private clouds can be expensive to set up and
maintain, and they may not offer the same level of scalability and flexibility as public
clouds.
Which of the following is defined as a storage technology that provides access to files as a
file system over a network? - Correct Answer File Storage
Explanation
File Storage is a cloud storage technology that provides access to files as a file system
over a network. File Storage is suitable for storing files that require frequent access, such
as documents, images, and media files. SAN is a high-speed network that provides block-
level access to storage devices, and does not provide access to files as a file system over
a network. SANs are typically used for block-level storage, rather than file-level storage.
Cloud storage is a model of data storage where data is stored on remote servers
accessed over the internet. While cloud storage can be used for file-level storage, it is not
a specific storage technology that provides access to files as a file system over a network.
Object storage is a storage architecture that manages data as objects, rather than as files
or blocks. Object storage is typically used for storing unstructured data and is optimized
for massive scalability and durability.
