• Question 1027:

  Refer to the exhibit.

  

  A network engineer is enabling logging to a local buffer, to the terminal and to a syslog server for all debugging level logs filtered by facility code 7.

  Which command is needed to complete this configuration snippet?

  A. logging buffered debugging

  B. logging discriminator Disc1 severity includes 7

  C. logging buffered discriminator Dlsd debugging

  D. logging discriminator Disc1 severity includes 7 facility includes fac7

  Correct Answer: D

  The "logging discriminator Disc1 severity includes 7 facility includes fac7" command enables the logging discriminator named Disc1 to filter messages with a severity level of 7 (debugging level) and facility code 7.

• Question 1029:

  What NTP Stratum level is a server that is connected directly to an authoritative time source?

  A. Stratum 0

  B. Stratum 1

  C. Stratum 14

  D. Stratum 15

  Correct Answer: B

  The stratum levels define the distance from the reference clock. A reference clock is a stratum 0 device that is assumed to be accurate and has little or no delay associated with it. Stratum 0 servers cannot be used on the network but they are directly connected to computers which then operate as stratum-1 servers. A stratum 1 time server acts as a primary network time standard.

  

  A stratum 2 server is connected to the stratum 1 server; then a stratum 3 server is connected to the stratum 2 server and so on. A stratum 2 server gets its time via NTP packet requests from a stratum 1 server. A stratum 3 server gets its time via NTP packet requests from a stratum-2 server... A stratum server may also peer with other stratum servers at the same level to provide more stable and robust time for all devices in the peer group (for example a stratum 2 server can peer with other stratum 2 servers). NTP uses the concept of a stratum to describe how many NTP hops away a machine is from an authoritative time source. A stratum 1 time server typically has an authoritative time source (such as a radio or atomic clock, or a Global Positioning System (GPS) time source) directly attached, a stratum 2 time server receives its time via NTP from a stratum 1 time server, and so on.
