If users cannot access a new server by name, but the server does respond to a ping request using its IP address, it means that there is a problem withname resolution. The DNS (Domain Name System) is a service that maps hostnames to IP addresses and vice versa. Therefore, the best step to perform next is to examine the DNS to see if the new server record exists and matches its IP address. If not, the DNS record needs to be added or updated accordingly. Running the tracert command from a workstation would not help with name resolution, as it only shows the route taken by packets to reach a destination by IP address. Correcting the missing DHCP scope would not help either, as DHCP (Dynamic Host Configuration Protocol) only assigns IP addresses and other network settings to clients, but does not resolve names. Updating the workstation hosts file would be a temporary workaround, but not a permanent solution, as it would require manually editing every workstation’s hosts file with the new server’s name and IP address.

The server is not joined to the domain is causing the issue. A domain is a logical grouping of computers that share a common directory database and security policy on a network. Active Directory is a Microsoft technology that provides domain services for Windows-based computers. To use Active Directory credentials to log on to a server, the server must be joined to the domain that hosts Active Directory. If the server is not joined to the domain, it will not be able to authenticate with Active Directory and will only accept local accounts for logon. To join a server to a domain, the administrator must have a valid domain account with sufficient privileges and must know the name of the domain controller that hosts Active Directory.

 The technician should configure RAID 6 for this drive array to meet the server specifications. RAID 6 is a type of RAID level that provides fault tolerance and performance enhancement by using striping and dual parity. Striping means dividing data into blocks and distributing them across multiple disks to increase speed and capacity. Parity means calculating and storing extra information that can be used to reconstruct data in case of disk failure. RAID 6 uses two sets of parity information for each stripe, which are stored on different disks. This way, RAID 6 can handle up to two disk failures without losing any data or functionality. RAID 6 also allows for theleast amount of drive space lost to RAID overhead compared to other RAID levels that can handle two disk failures, such as RAID 1+0 or RAID 0+1.

The server installation method that would optimize server resources is core. Core is a minimal installation option that is available for some operating systems, such as Windows Server and Linux. Core installs only the essential components and features of the operating system, without any graphical user interface (GUI) or other unnecessary services or applications. Core reduces the disk footprint, memory usage, CPU consumption, and attack surface of the server, making it more efficient and secure. Core can be managed remotely using command-line tools, PowerShell, or GUI tools.
