Question 1 answer A is perhaps:
switchport voice vlan 10
https://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/113260-voice-vlan-00.html
The answer for Q1 should be switchport voice vlan #(from 1 to 4094 whatever option you will get), see the explanation below:
Configuring Ports to Carry Voice Traffic in 802.1P Priority Tagged Frames
Beginning in privileged EXEC mode, follow these steps to configure a port to instruct the IP phone to
give voice traffic a higher priority and to forward all traffic through the native VLAN.
To return the port to its default setting, use the no switchport voice vlan interface configuration
command.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id Specify the interface connected to the IP phone, and enter interface
configuration mode.
Step 3 switchport voice vlan vlan-id Instruct the Cisco IP phone to forward all voice traffic through the specified
VLAN. By default, the Cisco IP phone forwards the voice traffic with an
802.1Q priority of 5.
Valid VLAN IDs are from 1 to 4094 when the enhanced software image (EI)
is installed and 1 to 1001 when the standard software image is installed. Do
not enter leading zeros.
Step 4 end Return to privileged EXEC mode.

I was thinking same thing exactly
RM1-C3560-0(config-if)#switchport ?
access Set access mode characteristics of the interface
autostate Include or exclude this port from vlan link up calculation
backup Set backup for the interface
block Disable forwarding of unknown uni/multi cast addresses
host Set port host
mode Set trunking mode of the interface
nonegotiate Device will not engage in negotiation protocol on this interface
port-security Security related command
priority Set appliance 802.1p priority
private-vlan Set the private VLAN configuration
protected Configure an interface to be a protected port
trunk Set trunking characteristics of the interface
voice Voice appliance attributes
RM1-C3560-0(config-if)#switchport voice vlan
