  • To translate domain names to IP addresses and vice versa.

Q2) How does a new endpoint know the address of the DHCP server ?

  • The endpoint sends a DHCP Discover circulate request to all endpoints on the local network.

Q3) Which Syslog layer contains the bodily message contents ?

  • Syslog Content

Q4) True or Imitation: Setting the correct Syslog Severity Level on systems helps proceed the Syslog server from being flooded past the millions of messages that could be generated past these systems.
