Question

Difficulty: MediumNetwork Host Services and Server Roles

A network administrator is documenting standard infrastructure services for an enterprise network audit. Match each network server role on the left with its primary function and associated default transport port/protocol parameters on the right.

  • Syslog ServerAggregates system status messages, event logs, and status notifications from network nodes using UDP port 514.
  • NTP ServerSynchronizes time clock signals across routers, switches, and client computers using UDP port 123.
  • DHCP ServerDynamically leases network IP configurations, default gateways, and DNS settings to hosts using UDP ports 67/68.
  • DNS ServerResolves fully qualified domain names (FQDNs) to IP addresses using UDP/TCP port 53.

Answer

Syslog Server pairs with aggregating system status messages and event logs using UDP port 514; NTP Server pairs with synchronizing time clock signals using UDP port 123; DHCP Server pairs with dynamically leasing network IP configurations using UDP ports 67/68; DNS Server pairs with resolving fully qualified domain names using UDP/TCP port 53.
Each core network server role performs a distinct service: Syslog collects diagnostic logging over UDP port 514; NTP maintains network-wide timestamp sync over UDP port 123; DHCP distributes network network IP settings dynamically over UDP ports 67/68; and DNS performs domain name resolution over port 53.

Step-by-Step Solution

1
Identify the primary role and port for Syslog.
Syslog collects system logs and operational notifications across appliances over UDP port 514.
Centralized logging enables security monitoring and network auditing.
2
Identify the primary role and port for NTP.
NTP maintains synchronized clock timing across client nodes and network hardware over UDP port 123.
Timestamp consistency across logs and authentication protocols relies on clock accuracy.
3
Identify the primary role and port for DHCP.
DHCP leases dynamic IP addresses, default gateways, and subnet masks using UDP ports 67 and 68.
Automated IP management eliminates manual configuration overhead on end-user hosts.
4
Identify the primary role and port for DNS.
DNS resolves human-friendly names (such as domain names) to machine-routable IP addresses on port 53.
Name resolution enables network users to locate hosts without memorizing numerical IP addresses.
