When you configure the Call Home feature on the Cisco Nexus 5000 Series Switch, which three parameters are mandatory? (Choose three.)

Contract ID is an optional Call Home field used to associate a device with a service contract, but the feature can be configured and will function without it.

The 'email-contact' parameter is mandatory because it defines the destination address for all Call Home alert notifications sent to Cisco TAC or the administrator.

'Switch priority' is a Spanning Tree Protocol parameter and has no relation to the Call Home feature configuration.

A phone number is required as a mandatory contact field so that Cisco support personnel can directly reach the responsible party when processing a Call Home-triggered support case.

Customer ID is an optional identifier that links alerts to a named account in Cisco's support systems but is not required for Call Home to operate.

Site ID is an optional descriptor used to label the physical site of the device but is not a mandatory parameter for Call Home configuration on the Nexus 5000.

The street address is a mandatory parameter that identifies the physical location of the device, which Cisco requires to dispatch field support or process hardware replacement.
