NCTI FIELD TECH 2 TO 3 PROGRESSION FINAL EXAM QUESTIONS AND CORRECT ANSWERS PASS GUARANTEED.

What uses the 2.4-GHz band and runs at 54 Mbps? - correct answer 802.11g What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once? - correct answer Changing the infrastructure all at once would cause too many service disruptions. What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) topologies? - correct answer An 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 passive optical network (PON)? - correct answer Optical splitters. Which type of star topology used in a passive optical network (PON) places the PON splitters into fiber access terminal (FAT) located deep in the network and closer to the customer premises than the centralized split? - correct answer Distributed star. Which element of a passive optical network (PON) uses a Bragg grating filter? - correct answer Optical line terminal (OLT). Which element of a passive optical network (PON) uses patch panels? - correct answer Optical distribution network (ODN). 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)? - correct 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? - correct 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? - correct 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? - correct answer Before stripping the plastic coating from the fiber. Which of the following are statements of true axioms? - correct answer When A = C and B = C, then A = B because both are equal to C, which supports the axiom: Quantities equal to the same quantity are equal to each other. Simplify and solve the equation: If E = IR then I = ? - correct answer E/R The square of 7 = - correct answer 49 The square root of 81 = - correct answer 9 0.00004 = ______ x 10 to the power of ______. - correct answer 4, -5 (75 x 10 to the power of 3) + (25 x 10 to the power of 4) = - correct answer 32.5 x 10 to the power of 4 10 to the power of -3 has a metric prefix of ______. - correct answer Milli (480 x 10 to the power of -5) divided by (60 x 10 to the power of -3) = - correct answer 8 x 10 to the power of -2 (250 x 10 to the power of -6) - (7 x 10 to the power of -5) = - correct answer 180 x 10 to the power of -6 (75 × 103) + (25 × 104) = - correct answer (*Wrong) 100 × 10^3 (-25) + (42) + (-62) + (20) = - correct answer -25 (17) x (-19) = - correct answer -323 (-17) - (-34) = - correct answer 17 -49/-7 = - correct answer 7 (20) / (-4) + (-2) x (-10) - (-2) x (7) = - correct answer 29 3 6/9 + 6 1/3 + 9 5/9 = - correct answer 19 5/9 4/7 x 9 4/11 = - correct answer 5 27/77 7 3/8 divided by 7 1/4 = - correct answer 1 1/58 8.13 X 0.123 = - correct answer 0.99999 0.5349 divided by 0.1420 = - correct answer 3.7669014 Which of the following is a method for controlling expectations? - correct answer Identify the source of emotional overload. Which of the following best describes stereotyped thinking? - correct answer Presuming that all members of a group have certain characteristics. The attribute of being "active" as a critical thinker means - correct 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? - correct 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? - correct answer A significant change in attitude with a noticeable movement toward negative, hostile, cynical, or paranoid thoughts You are at a customer's home and you are asking the customer whether the problem is intermittent or constant. Which step are you using from the six-step troubleshooting process? - correct answer Identifying the problem. Why should you take the time to take notes and accurately record data at each job location? - correct 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 the resolution did not introduce any new problems, which step are you using from the six-step troubleshooting process? - correct answer Verifying the solution. To break the habit of a negative self-talk cycle - correct 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 - correct answer More likely to improve your motivation and be a better problem solver.
