Question

Difficulty: MediumNetwork Host Services and Server Roles

A network administrator is setting up a new office subnet where client workstations need to automatically obtain network IP configurations and resolve domain names to local IP addresses. Which of the following server roles and protocol configurations should the administrator implement on the network? (Select TWO.)

  1. A DHCP server operating over UDP ports 67 and 68 to dynamically assign IP parameters.Answer
  2. A DNS server operating over TCP and UDP port 53 to translate computer hostnames into IP addresses.Answer
  3. C
    A DNS server operating over UDP ports 67 and 68 to lease IP configurations directly to endpoints.
  4. D
    An APIPA service operating over TCP port 443 to resolve internet domain names for remote clients.

Answer

The network administrator should deploy a DHCP server utilizing UDP ports 67 and 68 to dynamically assign IP configurations, and a DNS server utilizing port 53 to resolve domain names to IP addresses.
To satisfy both requirements, the network administrator needs a DHCP server to automatically lease IP addresses to client workstations and a DNS server to translate hostnames to IP addresses.

Step-by-Step Solution

1
Identify the network host service responsible for automated IP address distribution.
Dynamic Host Configuration Protocol (DHCP) automatically leases IP address configurations to client endpoints using UDP ports 67 and 68.
Automated network configuration eliminates manual static IP assignment for workstations.
2
Identify the network host service responsible for resolving names to IP addresses.
Domain Name System (DNS) translates computer hostnames into numerical IP addresses over port 53.
Workstations require hostname-to-IP resolution to connect to internal and external resources by name.
