DTS ST5102 FINAL EXAM UPDATED
ACTUAL QUESTIONS AND CORRECT
ANSWERS
◉ What is the difference between FTTN and FTTC
Answer: 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)
Answer: 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
Answer: Distributed Star
◉ Which element of a PON(Passive Optical Network) uses a Bragg
grating filter
Answer: OLT(Optical Line Terminal)
,◉ Which element of a PON(Passive Optical Network) uses Patch
Panels
Answer: 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)
Answer: 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
Answer: 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
Answer: 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
Answer: Before stripping the plastic coating from the fiber
◉ Which of the following is a method for controlling expectations
,Answer: focus on the bigger picture rather than smaller tasks
◉ Which of the following best describes stereotyped thinking
Answer: Presuming that all members of a group have certain
characteristics
◉ The attribute of being "active" as a critical thinker means
Answer: 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
Answer: 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 behavior
Answer: A significant change in attitude with a noticeable
movement toward negative, hostile, cynical, or paranoid thoughts
◉ You are at a customer's house and you are asking the customer
whether the problem is intermittent or constant. Which step are
you using from the six-step troubleshooting process
Answer: Identifying the problem
, ◉ Why should you take the time to take notes and accurately
record data at each job location
Answer: Notes and recorded data are tools that can help you
accurately remember events at a site that can help you determine
a plan of action or evaluate the decisions you made
◉ You are at a customer's home and you believe you have solved
the problem. When you check to be sure there are no new
problems, which step are you using
Answer: Verifying the Solution
◉ To break the habit of a negative self-talk cycle
Answer: Tell yourself "not now" and move onto a positive thought
whenever negative thoughts occur
◉ By taking control of the expectations you have you are
Answer: more likely to improve your motivation and be a better
problem solver
◉ Which of the following characterizes the successful
troubleshooter
Answer: Someone with an inquisitive and relentless desire to
solve and fix problems
◉ What must a technician be aware of when analyzing a Digital
TV(DTV) problem
