  • 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 broadcast asking to all endpoints on the local network.

Q3) Which Syslog layer contains the bodily bulletin contents ?

  • Syslog Content

Q4) True or Simulated: Setting the right Syslog Severity Level on systems helps keep the Syslog server from being flooded by the millions of messages that could be generated by these systems.

Q5) True or Imitation: The Syslog bulletin typically includes the severity level, facility lawmaking, originator process ID, a time stamp, and the hostname or IP address of the originator device.

  • True

Q6) Why is port mirroring used ?

  • To provide a stream of all data entering or leaving a specific port for debugging or analysis work.

  • NGFW use sessions.

Q2) Truthful or False: Unlike traditional stateful firewalls, next-generation firewalls drill into traffic to identify the applications traversing the network.

  • True

Q3) What are the two (ii) principal methods used by Intrusion Prevention Systems (IPS) to observe an exploit ?

  • Statistical anomaly-based detection.
  • Signature-based detection.

  • The subnet mask.

Q4) The IP header contains a fourth dimension-to-live (TTL) value. How is this value expressed ?

  • The number of Layer 3 devices (hubs, routers, etc.) the parcel is allowed to pass through before it is dropped.
