QSFP+ (Quad Small Form-factor Pluggable Plus) connectors are used in high-density, high-speed networking solutions such as 40 Gigabit Ethernet (40GbE) interfaces. When upgrading a server's network to 40Gbps, QSFP+ is the appropriate choice due to its capability to support such high-speed data transfer rates. 10 GigE, SFP, and SFP+ connectors are used for lower speed connections (10Gbps and below for SFP+ and 10 GigE, and even less for SFP), making them unsuitable for a 40Gbps network upgrade.

Using a network-based deployment, such as network booting (PXE - Preboot Execution Environment) or imaging through a server, is the most efficient way to load operating systems onto multiple machines simultaneously. This approach minimizes the manual intervention required for each device, as the administrator can initiate the operating system installation or imaging process across all desktops at once through the network. In contrast, using an SDcard, DVD (Optical), or USB would require the administrator to physically move the media from one desktop to another, significantly increasing the setup time for each device.

A DNS entry is a record that maps a domain name to an IP address. If the DNS entry for the new application is incorrect, users will not be able to resolve the domain name to the correct IP address and port number. This will prevent them from accessing the application, even if the firewall rules allow port 8443. To fix this issue, the server administrator should verify and update the DNS entry for the new application.

Robocopy (Robust File Copy) is a command-line tool in Windows that is designed for reliable copy or mirroring of files, and it can handle a broader range of file names and paths, including those that do not conform to traditional Windows file-naming standards. It's specifically designed to handle complex file copy demands and offers a wide range of options that can be tailored for different scenarios, which makes it suitable for the task mentioned. SCP (Secure Copy Protocol), Drag and Drop, and FTP (File Transfer Protocol) are all methods that can be used to copy files, but they might not handle non-standard Windows file names as well as Robocopy.
