Which of the following are characteristics of traditional monolithic services. (Select 2)
Correct Answer: A,C
The characteristics of traditional monolithic services are low scalability and fixed capacity. Monolithic services are applications that are built as a single unit, where all the components are tightly coupled and run in the same process. This makes them hard to scale, as they require more resources and coordination to handle increased demand. Monolithic services also have fixed capacity, as they are designed for a specific workload and cannot adapt to changing requirements or traffic patterns. Monolithic services are often slow to deploy, as they require updating the entire application for any change or improvement.

Question 12
What is the most critical benefit a cloud native deployment provides when deploying applications in complex and very low predictive environments?
Correct Answer: B
Adaptability is the most critical benefit a cloud native deployment provides when deploying applications in complex and very low predictive environments. Cloud native applications are designed to be modular, scalable, resilient, and portable across different cloud platforms1. They can leverage the cloud features such as automation, orchestration, and service discovery to dynamically adjust to changing conditions and demands2. This enables them to cope with the complexity and unpredictability of the environments they operate in, such as edge computing, industrial automation, and smart cities3. Capability and reliability are also important benefits of cloud native deployment, but they are not the most critical ones. Capability refers to the ability to deliver high-performance and feature-rich applications that meet the user and business needs1. Reliability refers to the ability to ensure the availability and consistency of the applications despite failures or errors1. However, these benefits are not sufficient if the applications cannot adapt to the evolving and diverse scenarios they face in the real world.

Question 13
A group of small services combine to deliver user specific service.
Correct Answer: A
A group of small services combine to deliver user specific service is a true statement. This is the definition of microservices, which are a key component of cloud technologies and features. Microservices are independent, modular, and scalable services that communicate with each other through APIs. They enable faster and easier development, deployment, and maintenance of cloud applications.

Question 15
In a cloud deployment, SaaS can stand for which of the following? (Select 2)
Correct Answer: B,D
Security as a Service and Software as a Service are two examples of SaaS in a cloud deployment. Security as a Service is a model where security services such as firewall, antivirus, encryption, etc. are delivered over the Internet by a cloud provider1. Software as a Service is a model where software applications such as email, CRM, ERP, etc. are hosted and managed by a cloud provider and accessed by users over the Internet2. Stack as a Service and Service as a Service are not valid terms for SaaS in a cloud deployment. Stack as a Service is a typo for Stack Overflow, a popular online platform for developers3. Service as a Service is a redundant and meaningless term that does not describe any cloud service model4. Reference: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.3: Cloud Service Models 2: Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.3: Cloud Service Models 3: Stack Overflow 4: What is Service as a Service (SaaS)? SaaS within cloud computing primarily stands for Software as a Service, which delivers software applications over the internet on a subscription basis. It allows users to connect to and use cloud-based apps over the Internet, such as email, calendaring, and office tools (like Microsoft Office 365). Security as a Service (SECaaS) is an outsourcing model for security management. Typically, businesses utilize this service for functions like anti-virus software, intrusion detection, and authentication. SECaaS is also considered a type of SaaS where security services are delivered remotely via the internet. Therefore, both Software as a Service and Security as a Service are correct answers, emphasizing the diversity of services provided through the SaaS model beyond just software applications.
