Citrix-Architecting a Citrix Networking Solution

Three Cisco Catalyst switches have been configured with a first-hop redundancy protocol. While reviewing some show commands, debug output, and the syslog, you discover the following information:
What conclusion can you infer from this information?

You administer a network that uses two routers, R1 and R2, configured as an HSRP group to provide redundancy for the gateway. Router R1 is the active router and has been configured as follows:
Which of the following describes the effect the "standby preempt delay minimum 50" command will have on router R1?

Which first-hop redundancy solution listed would supply clients with MAC address 0000.0C07.AC0A for group 10 in response to an ARP request for a default gateway?

You want to allow Router R1 to immediately become the active router if its priority is highest than the active router fails. What command would you use if you wanted to configure this?

Routers R1 and R2 are configured for HSRP as shown below:
You have configured the routers R1 & R2 with HSRP. While debugging router R2 you notice very frequent HSRP group state transitions. What is the most likely cause of this?

In the hardware address 0000.0c07.ac0a, what does 07.ac represent?

HSRP has been configured between two Company devices. What kind of message does an HSRP configured router send out every 3 seconds?

The following command was issued on a router that is being configured as the active HSRP router.
standby ip 10.2.1.1
Which statement is true about this command?

What can be determined about the HSRP relationship from the displayed debug output?

Which command will ensure that R2 will be the primary router for traffic using the gateway address of 172.16.15.20?
