NCTI Field Tech 2 to 3 Exam Questions
and Answers22
To prevent hacker access to passwords and Internet protocol (IP) addresses, why would you
want to place wireless access points (AP) on switches instead of hubs? - ANSWERS-Switches
prevent the broadcast of packets to all network segments
What are some basic questions you should ask a customer before visiting the customer's facility
to perform a site survey - ANSWERS-The anticipated number of users, security required, data
throughput required, and budget
What info should you gather during the (WLAN) Site survey in a convention center for an up and
coming trade show - ANSWERS-ID who will be installing APA in ceiling that could be 40 ft high
What test should you perform during the site survey to enable the design engineer to
understand and control what the user's experience will be on the WLAN - ANSWERS-A data
throughput test
Why is it suggested that all data collected as part of a site survey for a wireless local area
network (WLAN) be included in the survey report as an attachment, appendix, or separate set of
documentation? - ANSWERS-The data could be needed in the future
What are some of the AP facts that should be detailed in a WLAN site survey - ANSWERS-
Location within facility, antenna type to be used, power output settings, how power will be
provided to unit, and the expected data throughput per unit
Ideally, what should your next step be after you complete the wireless local area network
(WLAN) site survey and provide the survey results in a report to the customer? - ANSWERS-A
,wireless consulting firm should be given the site survey so that they will then be able to provide
effective info on equipment purchasing and security solutions
What should you note in the WLAN site survey if a semi directional antenna is required for
adequate coverage - ANSWERS-The antenna orientation along with the antenna's side and back
lobes for coverage and security reasons
What are some desired features of an AP used to perform WLAN site survey - ANSWERS-
Variable output power and external antenna connectors
What is one reason why broadband cable operators install fiber optic cables in stages instead of
changing the infrastructure all at once - ANSWERS-Changing the infrastructure all at once would
cause too many service disruptions
What is the difference between FTTN and FTTC - ANSWERS-FTTC is allowed a smaller number of
RF amplifiers between the optical fiber and the customer premises
Which of these components is used in a PON(Passive Optical Network) - ANSWERS-Optical
Splitters
Which type of Star topology used in a PON(Passive Optical Network) places the PON splitters
into FATS(Fiber Access Terminals) located deep in the network and closer to the customer
premises than the centralized split - ANSWERS-Distributed Star
Which element of a PON(Passive Optical Network) uses a Bragg grating filter - ANSWERS-
OLT(Optical Line Terminal)
Which element of a PON(Passive Optical Network) uses Patch Panels - ANSWERS-ODN(Optical
Distribution Network)
, What is it about Radio Frequency over Glass(RFoG) that made broadband cable operators
envision using it to make a seamless transition from the legacy hybrid/fiber coax(HFC)
architecture over to a gigabit-capable passive optical network (GPON) or Ethernet passive
optical network (EPON) - ANSWERS-RFoG can operate in parallel with GPON or EPON, which
eliminates the need for any downtime during the transition
How are optical splitters used in the forward path - ANSWERS-In the forward path, optical
splitters are used as passive branching devices that divide an optical signal across multiple
output fibers
Which of the following describes a fiber pigtail - ANSWERS-Fiber-optic cable with pre-
connectorized ends
Heat Shrink tubing is installed over the fusion-splice to strengthen and protect it. When should
the heat shrink be installed on the fiber - ANSWERS-Before stripping the plastic coating from the
fiber
Which of the following is a method for controlling expectations - ANSWERS-focus on the bigger
picture rather than smaller tasks
Which of the following best describes stereotyped thinking - ANSWERS-Presuming that all
members of a group have certain characteristics
The attribute of being "active" as a critical thinker means - ANSWERS-You observe and take
notes relevant to the issue
What kind of reasoning is described as applying a general statement that you know to be true to
a new situation - ANSWERS-Deductive
It is essential to pay attention to warning signs of stress overload. Poor attitude is one of the
behaviors that may indicate that you are overstressed. What are the symptoms of poor attitude
