Exam 35: Developing Applications for Cisco Webex and Webex Devices (DEVWBX)

As part of an IoT project, an organization is developing an application that will share multiple clients using a REST API. Based on the software development process, what are two valid technical activities that can be suggested to secure the REST API that is developed during the development of the software? (Choose two.)

Refer to the exhibit. Which two statements about MQTT messaging are true? (Choose two.)

Which two actions must be completed before starting the process of sending IoT data to the cloud via edge routers? (Choose two.)

What are two functionalities of edge data services? (Choose two.)

A network is being configured for an Ethernet-connected sensor. The sensor fails to send data to the configured destination. The IP address of the sensor can be pinged from a laptop on the same subnet. When a different subnet is used, the sensor cannot be reached, but other clients on the same subnet are still accessible. What are two reasons for the connectivity problem? (Choose two.)

Which statement explains the correct position of a PLC within the CPwE architecture?

Refer to the exhibit. When a laptop is connected to a device via a serial connection, which action makes the output readable?

Refer to the exhibit. Which two statements are true? (Choose two.)

Refer to the exhibit. While troubleshooting an error on an application descriptor for a Docker app in Cisco IOx (package.yaml), the app type appears to be missing. Which app type must be added to the snippet to resolve the issue?

Which two data sources are used with a visualization tool such as Grafana? (Choose two.)

A customer is deploying sensors with Cisco IR829 routers in moving trucks to continuously monitor the health of engines using a cloud application. Which data extraction and processing strategy is best suited in this environment?

Which command is used to package a Docker-style Cisco IOx app using ioxclient?

Which element ensures that PKI is used to establish the identity of IoT devices?

When an RS232 device is connected to a Cisco IR829 router, the data collected is not being parsed correctly by the edge application. Which two steps should be taken to troubleshoot the issue? (Choose two.)

Refer to the exhibit. When a Docker image is built using this Dockerfile, which two statements are valid on Cisco IOx 1.8 and before? (Choose two.)

Refer to the exhibit. A new application has just been developed as a Docker container. What is the missing step for packaging the container ready for deployment in IOx?

Refer to the exhibit. Which protocol is used to make a FlexVPN connection from a Cisco IR829 router to a headend router?

An IoT application has been built into the application CI/CD pipeline. The application needs credentials to access other applications, APIs, and cloud resources. When should the credentials be inserted into the application using the CI/CD process?

Refer to the exhibit. The code snippet provides information about the packet captures within a network. How can the most used source IP addresses within a specific time be visualized?

Mosquitto was installed correctly on the Cisco IR829 router as a Cisco IOx application. When the sensor is connected to the broker on the Cisco IR829 router with the default port, the connection is refused (Error Code 5). Which action should be done to resolve the issue?
