Which statements about VRRP are correct? (Choose two.)

Pre-emption is enabled by default in VRRP, meaning a higher-priority router will immediately take over as the master if it comes online. This ensures the best available router is always forwarding traffic. The router priority is a configurable value from 1-255, not 0-4095. MD5 authentication is not supported with VRRP; VRRP uses plain text or no authentication. Secondary IP addresses are supported with VRRP, allowing the virtual router to respond to multiple IP addresses, which can be useful for scenarios like load balancing or supporting multiple subnets. VRRP is an open standard (RFC 3768), so it can be used with devices from various vendors, not just Cisco.
