Which of the following statements is true regarding the installation of server roles and features?

• A. All roles require static IP addresses
• B. Some roles require static IP addresses
• C. No roles require static IP addresses
• D. All roles need domain authentication

Answer: (B)

The statement that some roles require static IP addresses is true because specific server roles, such as domain controllers, DNS servers, and certain web servers, benefit from having a static IP address. A static IP address ensures consistent availability and easier management, as it allows other devices on the network to reliably locate and communicate with the server based on the same address over time.

Dynamic IP addresses, on the other hand, can change if the DHCP server assigns a new address or if the server is rebooted, which could cause connectivity issues for services that depend on consistent network paths.

While some server roles may not require static IP addresses, relying on them for critical server functions helps prevent disruptions and supports streamlined operations. In contrast, roles that do not require strict static addressing, like certain email servers or application servers, may function adequately with dynamic addressing but typically with certain limitations regarding ease of access and reliability.
