An engineer is configuring a switch port that is connected to a VoIP handset. Which command must the engineer configure to enable port security with a manually assigned MAC address of abcd.abcd.abcd on voice VLAN 4?
An engineer is configuring a switch port that is connected to a VoIP handset. Which command must the engineer configure to enable port security with a manually assigned MAC address of abcd.abcd.abcd on voice VLAN 4?
To enable port security with a manually assigned MAC address on a voice VLAN, the correct command is switchport port-security mac-address abcd.abcd.abcd vlan voice. This command specifies the MAC address allowed on the port and identifies that it should be associated with a voice VLAN. The other options either lack the correct VLAN specification or include incorrect syntax for this configuration.
C. switchport port-security mac-address abcd.abcd.abcd To enable port security with a manually assigned MAC address, the engineer would use the "switchport port-security mac-address abcd.abcd.abcd" command. This command sets the allowed MAC address for the port. The VLAN assignment for the VoIP handset is separate and not included in the port-security command.
final question yay!
not for us ... :)

B switchport port-security [mac-address mac-address [vlan {vlan-id | {access | voice}}] Example: Switch(config-if)# switchport port-security mac-address 00:A0:C7:12:C9:25 vlan 3 voice https://www.cisco.com/en/US/docs/switches/lan/catalyst3850/software/release/3.2_0_se/multibook/configuration_guide/b_consolidated_config_guide_3850_chapter_011111.html
this is correct. I tested A in an actual device and the port must be in trunk mode for it to function. I don't think C works as intended as well, and B is just wrong for this
(Optional) Use the switchport port-security mac-address -mac-address- interface subcommand to predefine any allowed source MAC addresses for this interface. Use the command multiple times to define more than one MAC address.
A is correct the command is switchport port-security [mac-address mac-address [vlan {vlan-id | {access | voice}}] Example: Switch(config-if)# switchport port-security mac-address 00:A0:C7:12:C9:25 vlan 3 voice https://www.cisco.com/en/US/docs/switches/lan/catalyst3850/software/release/3.2_0_se/multibook/configuration_guide/b_consolidated_config_guide_3850_chapter_011111.html#ID437 and since in the questionit stated vlan 4 and you can have multiple Voice Vlans , A is more accurate than B
The "switchport port-security vlan vlan-id" command is applied on trunk ports. So it cannot be applied in this situation, due to the switchport must be configured as an access-port.

We can do this!
It´s C - port is an access port, so no vlan command
'switchport port-security mac-address abcd.abcd.abcd vlan 4' is possible. However, it is possible when it is a 'trunk' port. The problem is that it is an access port and vlan cannot be configured because it is connected to handset.
Enter one of these options after you enter the vlan keyword: vlan-id—On a trunk port, you can specify the VLAN ID and the MAC address. If you do not specify a VLAN ID, the native VLAN is used. access—On an access port, specifies the VLAN as an access VLAN. voice—On an access port, specifies the VLAN as a voice VLAN. It's more likely that it's access conncection becuase of the Voip, so we need to specify vlan voice as it stated here. *Check the link in 10th step: https://www.cisco.com/en/US/docs/switches/lan/catalyst3850/software/release/3.2_0_se/multibook/configuration_guide/b_consolidated_config_guide_3850_chapter_011111.html#ID437
B is correct, tested with a lab. C is for data vlan,
Answer is C

C is correct
A , can work if you used trunk mode in interface
C. Error, only MAC address specified without VLAN or port security enabled
