Router R1 and R2 are both configured for HSRP.  Which two statements about the HSRP priorities  of these two routers are true？（）

• A、 To assign the HSRP router priority in a standby group， the standby group-number priority  priority-value global configuration command must be used.
• B、 The default priority of a router is zero （0）.
• C、 The no standby priority command assigns a priority of 100 to the router.
• D、 Assuming that preempting has also been configured， the router with the lowest priority in an  HSRP group would become the active router.
• E、 When two routers in an HSRP standby group are configured with identical priorities， the router  with the highest configured IP address will become the active router.
