CompTIA Server+ (SK0-005)Server AdministrationEasy
A server administrator is deploying new virtual machines on an existing hypervisor cluster. The administrator needs to ensure that each new VM automatically receives an IP address, subnet mask, default gateway, and DNS server addresses upon startup. Which network service must be properly configured and accessible for this to occur?
- ALDAP
- BDHCP
- CNTP
- DDNS
Show answer & explanationAnswer & explanation
Correct answer: B. DHCP
DHCP (Dynamic Host Configuration Protocol) is responsible for automatically assigning IP addresses and other network configuration parameters to devices on a network. This ensures new VMs can communicate without manual configuration.
Why the other options are wrong
- A. LDAP (Lightweight Directory Access Protocol) is used for accessing and maintaining distributed directory information services, not for IP assignment.
- C. NTP (Network Time Protocol) synchronizes time across devices, but does not assign IP addresses.
- D. DNS (Domain Name System) translates domain names to IP addresses, but does not assign them.
DHCP
Dynamic Host Configuration Protocol is a network management protocol used on Internet Protocol (IP) networks for dynamically distributing network configuration parameters, such as IP addresses, for interfaces and services.
- Automates IP address assignment
- Distributes subnet mask, gateway, DNS
- Reduces manual configuration errors
Memory trick: Don't Have Confusing Protocols, Just DHCP for IPs!
