Question

Difficulty: MediumNetwork Host Services and Server Roles

A network technician is documenting network infrastructure roles for a newly deployed branch office. Match each network host service to its default transport port and primary operational function.

  • DHCP ServerUDP 67/68 - Dynamically provisions IPv4 network configurations to client hosts.
  • DNS ServerUDP/TCP 53 - Resolves human-readable domain names into numerical IP addresses.
  • Syslog ServerUDP 514 - Collects and centralizes system log messages from network devices.
  • NTP ServerUDP 123 - Synchronizes system time clocks across infrastructure hosts.

Answer

DHCP Server matches UDP 67/68 for dynamic IP address provisioning; DNS Server matches UDP/TCP 53 for name resolution; Syslog Server matches UDP 514 for centralized message logging; NTP Server matches UDP 123 for network clock synchronization.
Each host service performs a distinct administrative function: DHCP assigns IP parameters over UDP 67/68, DNS performs hostname lookup over port 53, Syslog gathers centralized logs over UDP 514, and NTP maintains temporal synchronization over UDP 123.

Step-by-Step Solution

1
Identify the protocol used for dynamic IP address assignment.
DHCP operates on UDP ports 67 (server) and 68 (client) to issue address configurations.
Automated host configuration relies on DHCP.
2
Identify the service responsible for hostname translation.
DNS maps domain names to IP addresses using port 53.
Name resolution is performed by DNS servers.
3
Associate logging and time services with their respective standard ports.
Syslog centralizes system status logs via UDP 514, while NTP standardizes network timing via UDP 123.
Syslog handles remote event logging and NTP ensures timestamp consistency across logs.
