Question 1

When trying to subscribe to an MQTT broker on the internet, the MQTT client is on a private subnet and must be NATed to reach the public broker.

What is the expected outcome when this configuration is in place?

AThe client periodically reconnects to the default gateway.

BThe client connects only once using the PENDING message to the broker.

CThe client periodically reconnects to the broker over the NAT connection.

DThe client connects only once using the CONNECT massage to the broker.

Answer : D

Question 2

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

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

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

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

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

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

Answer : D, E

Question 3

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.)

ASSH access on the Cisco IR829 router must be enabled for IOx Guest OS.

BCommunication mode must be set to half duplex over serial connection.

CSerial cable length should not exceed 1.5 meters.

DEnsure that communication parameters like baud rate and parity are set correctly.

ESet the cable connections based on the PIN layout from the sensor vendor.

Answer : D, E

Question 4

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

Acreating a machine learning data model

Bsupporting many interfaces and APIs

Capplying advanced data analytics

Answer : C

Question 6

As part of an IoT project, an organization is developing an edge application that will run on a gateway to securely transmit sensor information it receives into an IoT cloud. Based on the Agile software development lifecycle, the development team is planning to implement a CI/CD pipeline.

Which two methods should be suggested to make the software development lifecycle more secure during the implementation and testing? (Choose two.)

APerform automated code reviews prior to deployment.

BImplement auto-provisioning security inspection for the code.

CPerform on-going penetration testing on the system.

DPerform a GAP analysis on current security activities and policies.

ETrain members of the team in a secure software development lifecycle methodology such as OWASP.

Answer : D, E

Question 7

A sensor reads potentially critical data from an industrial device, but most of the data from the sensor is not critical information and does not change unless a critical event happens.

Which data work flow is appropriate for how the critical and non-critical data is processed?

A1. Acquire sensor data.
2. Filter non-actionable data.
3. Perform action on data.
4. Send critical data and action performed on data to cloud for storing.

B1. Acquire sensor data.
2. Send data to cloud for processing and to determine action.
3. Send required action back to edge for action completion.
4. Perform action on data.

C1. Acquire sensor data.
2. Filter non-actionable data.
3. Perform action on data.

D1. Acquire sensor data.
2. Perform action on data.
3. Send data and action performed on data to cloud for recording.
