Question 1

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?

AInsert in the IOS config: ip nat inside source static tcp <CAF IP> 1883 interface GigabitEthernet0 1883

BInsert in the package_config.ini file under section ports: tcp: ['8883']

CUse the correct username and password.

DInsert in the package.yaml file under section ports: tcp: ['1883']

Answer : C

Question 2

Refer to the exhibit.

Which protocol is used to make a FlexVPN connection from a Cisco IR829 router to a headend router?

ASSL

BIKEv2

CNAT

DIS-IS

Answer : B

Question 3

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 4

The environment for an Industrial IoT project in a large open pit mine is being scoped. The location has a large amount of dust and the device will be exposed to less than 1 meter of water temporarily.

When the edge device is being chosen, which Ingress protection rating must be used?

AIP37

BIP61

CIP67

DIP76

Answer : C

Question 5

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.

Answer : D

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

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

APLCs are always part of Level 0 -- process control.

BPLCs are part of Level 4 -- site business planning.

CPLCs are part of Level 1 -- basic control.

DPLCs are placed at Level 2 -- area supervisory control.
