Exam 642-813: Implementing Cisco IP Switched Networks (SWITCH 642-813) (October 26th, 2014)

where are the two optimal locations for trust boundaries to be configured by the network administrator?

A network is deployed using recommended practices of the enterprise campus network model,
including users with desktop computers connected via IP phones. Given that all components are
QoS-capable, where are the two optimal locations for trust boundaries to be configured by the
network administrator? (Choose two.)

What is the most likely cause of this status?

hostname Switch1

interface Vlan10
ip address 172.16.10.32 255.255.255.0
no ip redirects
standby 1 ip 172.16.10.110
standby 1 timers msec 200 msec 700
standby 1 preempt
hostname Switch2
interface Vlan10
ip address 172.16.10.33 255.255.255.0
no ip redirects
standby 1 ip 172.16.10.110
standby 1 timers msec 200 msec 750
standby 1 priority 110
standby 1 preempt
hostname Switch3
interface Vlan10
ip address 172.16.10.34 255.255.255.0
no ip redirects
standby 1 ip 172.16.10.110
standby 1 timers msec 200 msec 750
standby 1 priority 150
standby 1 preempt
Refer to the above. Three switches are configured for HSRP.
Switch1 remains in the HSRP listen state. What is the most likely cause of this status?
