A company's server-naming convention is overly complicated.
The systems administrator wants to change the naming convention to make it easier for users to remember which hosts they should log into.
However, renaming servers is complicated and requires some downtime.

The DNS (Domain Name System) is a hierarchical distributed naming system that maps domain names to IP addresses. It allows users to use easily memorable domain names to access websites and other network resources instead of using the numerical IP addresses.
In the scenario provided, the systems administrator wants to make it easier for users to remember which hosts they should log into, but changing server names can be complicated and require some downtime. Therefore, the administrator needs to find a solution that would accomplish this goal without requiring servers to be renamed.
The DNS record types are used to provide different types of information about domain names and their corresponding IP addresses. Here are brief explanations of the DNS record types listed in the question:
A (Address) Record: A DNS record type that maps a domain name to an IP address.
TXT (Text) Record: A DNS record type that can contain any text information. It is commonly used for adding comments or other human-readable notes to a DNS zone.
SRV (Service) Record: A DNS record type that provides information about available services in a domain. It is often used for locating servers for specific services.
CNAME (Canonical Name) Record: A DNS record type that maps an alias name to a canonical name. It is often used to provide alternative names for a server or other resource.
Among the options provided, the CNAME (Canonical Name) record is the most suitable for accomplishing the goal of making it easier for users to remember which hosts they should log into without requiring server renaming.
A CNAME record maps an alias name to a canonical name, which means it provides an alternative name for a server or other resource. By creating a CNAME record, the administrator can use a simpler and more memorable name for the server that users can easily remember. For example, instead of using a complex server name like "server-1234.example.com," the administrator can create a CNAME record that maps "apps.example.com" to "server-1234.example.com." This way, users can access the server by typing in the easier-to-remember name "apps.example.com" instead of the more complex name.
In conclusion, the DNS record type that would accomplish the goal of making it easier for users to remember which hosts they should log into without requiring servers to be renamed is CNAME (Canonical Name) Record.
