What type of virtual server should be used to load balance UDP traffic without considering...

When handling high-volume UDP traffic where the BIG-IP does not need to maintain any session history or relationship between packets, aStatelessvirtual server is the appropriate choice.

No Connection Tracking:A stateless virtual server does not create or maintain entries in the BIG-IP connection table. This means the system processes each packet as an individual event, without "considering previous connections" or packets from the same source.

High Performance:Because the system bypasses the overhead of state management, stateless virtual servers provide the highest possible throughput for UDP and ICMP traffic.

Use Cases:This is ideal for services like DNS (stateless queries) or some types of syslog traffic where each packet is independent and doesn't require the persistence or protocol inspection typically provided by a full-proxy.

Why other options are incorrect:

Forwarding:While a Forwarding (IP) virtual server can handle UDP, it still maintains a state entry in the connection table to ensure return traffic is handled correctly.

Standard:This is a full-proxy virtual server. It is inherently stateful and requires a connection table entry for every flow it manages.

Reject:This is a special virtual server type that simply drops incoming traffic and, in the case of TCP, sends a reset (RST) or, for UDP, sends an ICMP unreachable message. It is not a load balancing type.
