What could be a possible issue if several computers on a network are assigned the wrong DNS server IP address while using DHCP?

• A. A misconfigured static IP address
• B. Someone has setup another DHCP server
• C. Insufficient network bandwidth
• D. Expired DHCP leases

Answer: (B)

Assigning the wrong DNS server IP address to several computers on a network can indeed lead to significant issues, particularly if someone has set up another DHCP server. When multiple DHCP servers operate concurrently on the same network without coordination, it creates a situation where computers might receive conflicting configurations. This could result in some devices getting the correct DNS server address while others receive the incorrect one, leading to inconsistent network behavior and difficulty in resolving domain names. In the context of using DHCP, each server is responsible for assigning IP configurations, including DNS settings, to devices on the network. If a rogue or unauthorized DHCP server is active, it can distribute its own DNS settings, thereby overriding the configurations provided by the legitimate DHCP server. This can lead to network reliability issues, as affected computers may struggle to reach external sites or services due to incorrect DNS resolution. The other choices refer to issues that, while they may impact network functionality, do not directly relate to the assignment of incorrect DNS server addresses. A misconfigured static IP address pertains to devices that are manually assigned an IP address and would not necessarily involve DHCP behavior. Insufficient network bandwidth concerns performance rather than misconfiguration of DNS settings, and expired DHCP leases typically lead to clients losing their IP address rather than receiving the wrong DNS
