A network administrator is configuring an IPsec VPN tunnel for a sales employee travelling abroad.

For configuring an IPsec VPN tunnel for a sales employee traveling abroad, the "Remote Access" template is the most appropriate choice. This template is designed to allow remote users to securely connect to the internal network of an organization from any location using FortiClient or a compatible client. The other options, such as "Site to Site," "Dial up User," and "iHub-and-Spoke," are used for connecting different networks or sites, not individual remote users.
