Exam Question 1 *

Industrial wireless RF technology strategy should include:

A single selection of a specific standard, no proprietary networks, ISM bands only, and managed by the IT department
A designated team leader, a full documented wireless FEED, RF environment management plan, and a plan for scalability
A single vendor selection on hardware, no more than 200 nodes throughout a facility, a wireless manager, a single gateway
Special FCC licensing, limited to a specific frequency band, use DSSS (Direct Sequencing Spread Spectrum) only, and not have to require a site survey
Exam Question 2 *

A site industrial wireless network could include:

Hand held HMI/remote worker, multiple unique sensor networks, SCADA and HMI networks, Security and Safety, and more
Should be limited to sensor networks only
The facilities business network to allow the users to check e-mail and the corporate web site
None of the above
Exam Question 3 *

If the industrial wireless network was installed by a vendor and it failed:

Accept the fact that wireless probably won’t work in your plant or facility
Add more routers until it connects; at the cost of $1,000 per router it’s not significant
Ensure the installing source has performed a complete comprehensive documented study, delivered the results before installation and is trusted
Go to a different vendor as most wireless solutions work very good
Exam Question 4 *

Which of the following is an accepted ISA P&ID symbol for wireless?

Dashed line
Lightning bolt
Sine wave
Exam Question 5 *

Who should manage the RF network at your location?

A competent controls individual in RF technology basics and network design
The group that handles the walkie-talkies
IT department
You and you alone
Always an outside source
Exam Question 6 *

Appropriate steps for a wireless installation in an industrial environment are:

Engage senior-level engineering teams with proper credentialing for passive and active surveys to each location; develop computer-based modeling of each facility in order to develop highly accurate radio frequency (RF) model and drive final design and bill of materials; retain RF engineers for oversight of installation process; perform commissioning, testing and validation
Develop computer-based modeling of each facility in order to develop highly accurate radio frequency (RF) model and drive final design and bill of materials; perform commissioning, testing, and validation
Engage operational leads to raise funding for project based on single user needs; perform commissioning, testing and validation
Retain RF engineers to do everything
Exam Question 7 *

First steps in the wireless design development process include:

Requirements verification, engineering analysis (RF allowability, etc.), analysis of drawings, site walkdown (challenge briefings, etc.)
Active survey, passive survey, final design and BOM
Advanced modeling review, site walkdowns, and drawing review
B and C
Exam Question 8 *

Definitions for passive and active RF survey are:

Passive survey: Validation exercise for preliminary node placements. Active survey: RF data collection and preliminary design deliverable
Passive survey: RF data collection, spectrum analysis, building composition analysis, outdoor features/topology noted. Deliverable: preliminary design. Active survey: Validation exercise for our preliminary AP placements. Measure actual signal performance. Deliverable
Passive survey: Develop monitoring of machine health. Active survey: engage RF engineering team for walkdown and definition
Passive survey: Independent monitoring and diagnostics. Active survey: scope definition with project lead
Exam Question 9 *

Some of the benefits of wireless infrastructure in the industrial environment are:

Enhances change order process lead time, increases capabilities for paper based processes and lengthens out of field processing times
Creates stove-pipe solutions for specific operations, segregating offerings to single users
Creates single-source solutions, creating redundant maintenance support requirements
Provides ubiquitous communications capabilities, cross-operational value and utility, reduces lead-time and costs associated with wired cabling
Exam Question 10 *

The four aspects of CIIM Critical Infrastructure Integrity Monitoring Model are:

Field instrumentation, communications, analysis and storage, and presentation
Design drawing, performance, commissioning, and owner sign off
Passive survey, active survey, field instrumentation, and storage
Critical analysis, infrastructure integrity, monitoring, and modeling
