Question

Difficulty: MediumNetwork Host Services and Server Roles

A network infrastructure engineer is auditing management protocols and server roles across a corporate datacenter. Match each network host service or role on the left with its corresponding primary function and standard port assignment on the right.

  • Syslog ServerAggregates system status messages and event notifications from network infrastructure devices over UDP port 514.
  • NTP ServerSynchronizes time clocks across network endpoints and servers using UDP port 123.
  • IPAM ServerTracks, discovers, and manages the network IP address space and subnet allocations.
  • RADIUS ServerProvides centralized authentication, authorization, and accounting for network access control over UDP ports 1812/1813.

Answer

Syslog Server matches with UDP port 514 log aggregation; NTP Server matches with UDP port 123 clock synchronization; IPAM Server matches with IP address space tracking and planning; RADIUS Server matches with UDP ports 1812/1813 centralized AAA authentication.
Each service directly pairs with its official network function and port assignment: Syslog aggregates event logs on UDP 514; NTP synchronizes systems on UDP 123; IPAM tracks IP address allocations; and RADIUS delivers centralized AAA authentication on UDP 1812/1813.

Step-by-Step Solution

1
Identify the primary role and default port for log management.
Syslog uses UDP port 514 to collect status and diagnostic messages centralizing audit logs.
Security and network operations require centralized event logging.
2
Identify the primary role and default port for time synchronization.
NTP uses UDP port 123 to align time stamps across enterprise endpoints.
Consistent time stamps are necessary for accurate log correlation and domain authentication.
3
Identify the role designed for tracking IP address inventory.
IPAM monitors and plans subnet usage, static assignments, and DHCP scope integration.
Prevents IP address conflicts and simplifies network administration.
4
Identify the service providing network access control AAA functions.
RADIUS uses UDP ports 1812 (authentication) and 1813 (accounting) for centralized access management.
Consolidates credential verification for VPN, 802.1X wireless, and switch logins.
