Which of the following statements are true about network optimization measures?

Loops may occur if Ethernet cables are incorrectly connected to wall plate APs. In this case, loop detection can be enabled on the wired interfaces of APs to automatically block the interfaces once a loop is detected.

It is recommended that the Beacon interval be adjusted based on the number of VAPs. A long interval increases the sleep time of STAs, and a short interval increases the air interface overhead.

It is recommended that multicast packet suppression be enabled when multicast services are planned on the network.

The rate limit for STAs can be set based on customer requirements. In most cases, 10 Mbps bandwidth for uplink and downlink traffic can support common Internet access applications.
