A network engineer must expand a company's Cisco AnyConnect solution. Currently, a Cisco ASA is set up in North America and another will be installed in Europe with a different IP address. Users shoul

VPN Load Balancing distributes sessions across ASAs in the same cluster using a shared virtual IP address and does not measure client-side RTT or direct clients to geographically separate devices.

IP SLA monitors network path quality from the ASA or router perspective for routing decisions; it does not measure RTT from AnyConnect clients to headends.

DNS Load Balancing resolves a hostname to different IPs but does not perform client-side RTT measurement and cannot guarantee the lowest-latency connection for each user.

Optimal Gateway Selection is a built-in AnyConnect feature that uses client-initiated RTT probes to compare latency to configured headends and directs the user to the lowest-latency device. It is specifically designed for geographically distributed headends with different IP addresses. VPN Load Balancing cannot achieve this because it operates within a single cluster sharing a virtual IP, not across geographically distinct ASAs.
