Refer to the exhibit. Router R1 was recently included in HSRP group 1. On the basis of the debug standby terse output that is provided, which statement is true?
R2 will keep the active role, and R1 will become a standby router.
x R1 has promoted itself to the role of active router and R2 has assumed the role of standby router.
R2 promoted itself to the active role when its hold-down timer expired before it saw a better candidate for the role of active router.
R1 and R2 will alternate between the active and the standby role because of a conflict in the HSRP priority that is configured on the routers.

A network administrator is troubleshooting a connectivity issue in a Layer 2 switched network. After issuing the show mac-address-table command on the access switch, the administrator observes that there is no entry for the host that is experiencing the problems. The host machine is powered on and appears to be functioning normally. What can be deduced from this?
ARP does not function on the host machine.
The host machine is connected to the wrong port on the local switch.
x The host machine does not have a physical connection to the switched network.
The show mac-address-table command only displays the MAC address of devices that are connected to the native VLAN.
The show mac-address-table command only displays the destination MAC address, so there should not be an entry for the host machine until data is sent to it.
