You are implementing basic switch security best practices.
Which of these is a tactic that you can use to mitigate compromises from being launched through the switch？（）
A.Make all ports private VLAN ports.
B.Place all unused ports in native VLAN 1 until needed.
C.Proactively configure unused switch ports as access ports.
D.Disable Cisco Discovery Protocol globally.
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？（）
A.VRRP is initializing and operating correctly.
B.HSRP is not properly exchanging three hello messages.
C.VRRP is not properly exchanging three hello messages.
D.HSRP is initializing and operating correctly.
E.GLBP is not properly exchanging three hello messages.
F.GLBP is initializing and operating correctly.
You work as a network engineer for . You study the exhibit carefully. Three switches are configured for HSRP. Switch1 remains in the HSRP listen state.
What is the most likely cause of this status？（）
A.this is normal operation
B.IP addressing is incorrect
C.standby group number does not match VLAN number
D.incorrect standby timers
E.incorrect priority commands
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 1 5
standby 1 priority 130
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 1 5
standby 1 priority 120
HSRP was implemented and configured on two switches while scheduled network maintenance was performed.
After the two switches have finished rebooting， you notice via show commands that Switch2 is the HSRP active router.
Which two items are most likely the cause of Switch1 not becoming the active router？ （）
A.premption is disabled
B.standby group number does not match VLAN number
C.IP addressing is incorrect
D.IP redirect is disabled
E.incorrect standby timers
F.booting delays

What must be the same to make multiple switches part of the same Multiple Spanning Tree （MST）？（）
DS2 has not become the active device for Vlan103’s HSRP group even though all interfaces are active. As related to Vlan103’s HSRP group. What can be done to make the group function properly ？ （）
What is the configured priority value of the Vlan105’s group on DS2 ？（）
Refer to the exhibit. Which statement is true about the output？（）
During routine maintenance， G1/0/1 on DS1 was shutdown. All other interface were up. DS2 became the active HSRP device for Vlan101 as desired. However， after G1/0/1 on DS1 was reactivated. DS1 did not become the active HSRP device as desired. What need to be done to make the group for Vlan101 function properly ？ （）
Which two statements are true about BPDU port-guard and BPDU filtering？（）
Refer to the exhibit. STP has been implemented in the network. Switch SW_A is the root switch for the default VLAN. To reduce the broadcast domain， the network administrator decides to split users on the network into VLAN 2 and VLAN 10. The administrator issues the command spanning-tree vlan 2 root primary on switch SW_A. What will happen as a result of this change？（）
During routine maintenance， it became necessary to shutdown G1/0/1 on DS1 and DS2. All other interface were up. During this time， DS1 became the active device for Vlan104’s HSRP group. As related to Vlan104’s HSRP group. What can be done to make the group function properly ？ （）
Which option correctly identifies the Cisco IOS switching methods in descending order from the fastest method to the slowest method？（）
