On what interface(s) will ZTP send out requests?
  1. Only the management interface.
  2. Only the console.
  3. All interfaces.

Question 4

  1. show status xmpp
  2. show xmpp status
  3. show xmpp server
  4. show xmpp server status
Correct answer: B
Question 5
What does LANZ do?
  1. LANZ reports on microbursting events at extremely small intervals of time.
  2. LANZ alters the flow of frames based on an interfaces high and low queue-thresholds.
  3. LANZ is a form of QoS that allows for microsecond-levels of precision on interfaces that support it.
  4. LANZ is the means whereby late packets can be analyzed.
Correct answer: A
Explanation:
Data center switches sometimes suffer from a problem known as microbursting, wherein the buffers become overrun and drop packets. The problem is that these microbursts happen often at microsecond intervals, so the switches never report them. These prob lems can be horrific to diagnose, and even worse to try and explain to executives. That is, unless you have an Arista switch with latency analyzer (LANZ)

Question 8
ZTP can retrieve either an EOS configuration file or a script at boot. How does the switch determine of the file being retrieved in a script or a configuration file?
  1. If the first line of the file ends with a shebang (#!), the file is a configuration file.
  2. If the first line of the file starts with a shebang (#!), the file is a script.
  3. If the last line of the file ends with a shebang (#!), the file is a script.
  4. If the last line of the file starts with a shebang (#!), the file is a configuration file.
Correct answer: D
