Question:
Which three options are the HSRP states for a router? (Choose three)
- initialize
- learn
- secondary
- listen
- speak
- primary
Explanation: HSRP consists of 6 states:
| State | Description |
| Initial | This is the beginning state. It indicates HSRP is not running. It happens when the configuration changes or the interface is first turned on |
| Learn | The router has not determined the virtual IP address and has not yet seen an authenticated hello message from the active router. In this state, the router still waits to hear from the active router. |
| Listen | The router knows both IP and MAC address of the virtual router but it is not the active or standby router. For example, if there are 3 routers in HSRP group, the router which is not in active or standby state will remain in listen state. |
| Speak | The router sends periodic HSRP hellos and participates in the election of the active or standby router. |
| Standby | In this state, the router monitors hellos from the active router and it will take the active state when the current active router fails (no packets heard from active router) |
| Active | The router forwards packets that are sent to the HSRP group. The router also sends periodic hello messages |
Please notice that not all routers in a HSRP group go through all states above. In a HSRP group, only one router reaches active state and one router reaches standby state. Other routers will stop at listen state.
