In a large network, what is a more efficient solution for name resolution than editing a Host File?

Using a DNS (Domain Name System) is considered a more efficient solution for name resolution than editing a Host File due to several reasons.

DNS operates as a distributed database that converts user-friendly domain names into IP addresses. This system allows for dynamic resolution of names across a large network without the need for manual updates to individual systems. Compared to editing a host file, which would require each machine to have a unique file maintained and updated whenever changes occur, DNS centralizes name resolution. This centralization not only reduces administrative overhead but also minimizes errors and inconsistencies that can arise from manual edits.

Additionally, DNS supports hierarchical name resolution, caching, and is capable of handling large volumes of requests efficiently. It can also include features such as load balancing and redundancy, which are crucial for maintaining robust network communications, especially as the size and complexity of the network increase.

The other choices, such as implementing a master script, utilizing static IP addresses, or regularly updating the Host File, do not provide the same level of efficiency or scalability that DNS offers. A master script could automate some processes but would still require individual system maintenance. Static IP addresses can eliminate the need for name resolution but do not scale well, particularly in environments where devices frequently change. Regularly
