DRAG DROP

An engineering team developed a solution that gathers data via a proprietary protocol (TCP/IP based) to a IR1101 gateway, which then sends the data to the cloud. Drag and drop the action steps from the left into the correct order on the right to get this solution to operate. Not all options are used.

DRAG DROP

Drag and drop the tasks from the left into the correct order on the right for transporting data from sensors to the cloud, in order to extract the machine data and use the cloud-based analytics for predictive maintenance.

Select and Place:

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.)

A. wrong DNS server on the sensor

B. wrong subnet mask on your laptop

C. wrong default gateway on the sensor

D. wrong default gateway on your laptop

E. wrong subnet mask on the sensor

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

A. Measure the voltage, power rating, and quiescent current for the sensors that send data to the cloud.

B. Gather the hardware (MAC) addresses of local and cloud routers to ensure low latency communication.

C. Collect information about the CPU architecture in the cloud and edge to ensure that they match.

D. Gather the interval, the volume, and the latency that the data must be provisioned with.

E. Collect information about growth, required elasticity, and high availability of the provisioning process.

Where are edge data services typically instantiated?

A. at the edge of network

B. in the cloud

C. in the data center

D. in a private cloud
