Question

Difficulty: MediumNetwork Host Services and Server Roles

A network technician is setting up network infrastructure services for a newly established branch office segment. The branch office requirements state that host workstations must automatically acquire dynamic IP addressing parameters upon connecting to the network, and host computers must also be able to resolve human-readable domain names to their corresponding IP addresses for web browsing. Which of the following network host services or server roles must be active to satisfy these operational requirements? (Select TWO.)

  1. DHCP ServerAnswer
  2. DNS ServerAnswer
  3. C
    Syslog Server
  4. D
    NTP Server

Answer

The network host services required to fulfill these needs are the DHCP Server and DNS Server.
The DHCP Server role automatically distributes IP addressing settings to client hosts on link startup, fulfilling the requirement for dynamic IP configuration. The DNS Server role performs name resolution, translating user-friendly domain names into destination IP addresses for web browsing.

Step-by-Step Solution

1
Analyze the requirement for host workstations to automatically acquire dynamic IP addressing parameters.
Identify that dynamic allocation of IP configurations (IP address, subnet mask, default gateway) is the core function of a DHCP server operating on UDP ports 67 and 68.
Without a DHCP server, workstations would either require static IP configuration or self-assign an APIPA address (169.254.x.x169.254.x.x).
2
Analyze the requirement for host computers to resolve human-readable domain names into IP addresses.
Identify that hostname-to-IP resolution is performed by a DNS server operating on port 53.
DNS translates domain names into numerical IP addresses required for network routing and web connection establishment.
