Exam Topics

Before attempting Cisco 300-915, the students must make sure that they have a comprehensive understanding of the knowledge areas included in the exam content. The highlights of the topics covered in this certification test are provided below:

Topic 1. Network Internet of Things Architecture

The first objective of the certification exam evaluates the candidates based on their ability to interpret the topology data flow, including access points, gateways, firewalls, routers, switches. They are also required to have competency in describing the functionality, purpose, and utilization of the following operational technology elements: embedded microcontrollers, PLCs & operations, RTOS systems, communication protocols (LoraWAN, WiFi, Ethernet, and BLE), Cisco interfaces (sensors, USC, serial, and I2C), communication standards (OPC UA, Open PLC, DDS, and MT Connect). Moreover, the learners should be capable of explaining the Internet of Things requisites associated with networking & device customization policies, in particular customizing IOS commands to activate port, protocol, and IOx requirements of the application, as well as data security & prioritization. Their skills in building a workflow to join a sensor and fixing sensor connectivity problems are also required.

Topic 2. Analysis & Compute

The second topic focuses on the ability of the examinees to compare the parameters, capabilities, and usage of edge devices to common compute devices. They should also be proficient in identifying the usage of specific edge/Cloud tools for a particular application scenario, analyzing usage data of the application resource to identify any necessary modifications to hardware or application. Other skills evaluated within this subject area include building the Python script in order to perform the application deployment at the edge with the use of GMM & FND APIs, troubleshooting network connectivity as well as application resources utilization issues when applying GMM & FND APIs, identifying data management procedure and measure to take with edge information according to the business needs.

Topic 3. IOx Internet of Things Software

This domain requires one’s competency in the Cisco IOx app capacity. The potential candidates should be able to fix a Dockerfile for Cisco IOx, explain the procedure needed for constructing the apps for Cisco IOx, determine the troubleshooting techniques for a deployed app for Cisco IOx. They should also know how to explain the procedure to deploy the Cisco IOx app into a CI/CD on Kinetic GMM, FND, and Directly to IOx platforms as well as how to build a Cisco IOx app to satisfy the requirements according to the SDK documents.

Topic 4. Edge Data Internet of Things Software

The individuals’ skills measured within this section include describing the parameters of edge data services, examining a DSLink, as well as determining the procedure to send information to a public Cloud provider.

Topic 5. Open Source Internet of Things Software

To be able to answer the questions from this subject area, the students should possess the skills in assessing the data flow & processing from sensor to Cloud according to a certain scenario. They need to be conversant with comparing usage & characteristics of AMQP and MQTT, defining the output from messages & subscription details, determining a broker QoS level for messages according to a certain scenario, as well as diagnosing problems with application connection and broker deployment.

Topic 6. Internet of Things Data Visualization

Here the learners should prove that they have the expertise in describing the capabilities as well as parameters of the tools for data visualization, including Grafanna, Kibana, and Freeboard. They also need to understand how to determine the data visualization method to satisfy the business needs and how to explain visualized data.

Topic 7. Security

Within this last subject area, the test takers need to demonstrate their proficiency in defining methods to perform a secure software development lifecycle as well as techniques to secure an infrastructure & application during testing and production within a CI/CD pipeline. They should be also capable of explaining risk management (comprising possible security difficulties in IT & operational technology) as well as the concepts associated with integrity, confidentiality, and availability. Additionally, the individuals should be capable of describing the capacity of an ISE & ISE integration, AMP for Endpoints proxy, pxGRID, Cisco Tetration, StealthWatch (Cloud & Enterprise), as well as Cisco Cloudlock.

Career Path

After passing the Cisco 300-915 exam, the successful candidates will be able to apply for any of the following job roles: a Network Administrator, a Consulting Systems Engineer, a Network Engineer, an Internet of Things Designer, a Network Manager, a Sales Engineer, a Systems Engineer, and a Technical Solutions Architect, among others. The salary rate for these positions differs from one title to another. Working in the role of a Network Engineer, you can earn from $51,000 to $108,000 per annum. The position of a Network Manager can bring you from $58,000 to $128,000 per year.
