All NTP servers have access to highly precise atomic clocks and GPU clocks1 pointYesNo

Downstream NTP servers in the hierarchy derive their clock from servers  ______________________

Select the correct answer from the drop-down menu.Read paragraphs 11 and 12 from the passage.(11) Atomic clocks are used onboard GPS satellites that orbit the Earth, but even they must be sent updates two times per day to correct the clocks' natural drift. Those updates come from more stable atomic clocks on the ground that are large (often the size of a refrigerator) and not designed to survive the physical demands of going to space.(12) Up to 50 times more stable than the atomic clocks on GPS satellites, NASA's Deep Space Atomic Clock is intended to be the most stable atomic clock ever flown in space. It achieves this stability by using mercury ions.How does the detail about natural drift help refine the central idea of the passage?The detail about natural drift helps the reader to understand

NTP works only in the client-server environment 1 pointTrueFalse

Which two statements are true about NTP servers in an enterprise network? (Choose two.)

Select the correct answer.Read paragraphs 12 through 14 from the passage.(12) Up to 50 times more stable than the atomic clocks on GPS satellites, NASA's Deep Space Atomic Clock is intended to be the most stable atomic clock ever flown in space. It achieves this stability by using mercury ions.(13) Ions are atoms that have a net electric charge, rather than being electrically neutral. In any atomic clock, the atoms are contained in a vacuum chamber, and in some of those clocks, atoms interact with the vacuum chamber walls. Environmental changes such as temperature will then cause similar changes in the atoms and lead to frequency errors. Many atomic clocks use neutral atoms, but because the mercury ions have an electric charge, they can be contained in an electromagnetic "trap" to prevent this interaction from happening, allowing the Deep Space Atomic Clock to achieve a new level of precision.(14) For missions going to distant destinations like Mars or other planets, such precision makes autonomous navigation possible with minimal communication to and from Earth — a huge improvement in how spacecraft are currently navigated.How does the information in paragraph 12 connect the information provided in paragraphs 13 and 14? A. by explaining the similarities and differences between mercury ions and electrically neutral atoms B. by explaining how scientists determined that NASA's Deep Space Atomic Clock is 50 times more stable than atomic clocks on GPS satellites C. by explaining the process navigators use to calculate a spacecraft's trajectory using communications to and from Earth D. by explaining how the use of mercury ions in the Deep Space Atomic Clock makes autonomous navigation possibleReset Next© 2024 Edmentum.
