Question:
1. Which GLBP load-balancing algorithm is the default method used by the active virtual gateway?
2. In which submodule of the Enterprise Model should DiffServ traffic classification be performed?
3. How many bytes are added to Ethernet frames using the ISL trunking protocol?
4. An interface in DTP "dynamic auto" mode will convert to a trunk link if the neighboring interface is set to which DTP modes?
5. What does the 1f represent in the HSRP virtual MAC address 0x00000c07ac1f?
6. Which authentication protocol uses EAPOL frames between the client and the authenticator (switch)?
7. What is the default time it takes to transition from the STP blocking state to the listening state?
8. Which command should you use to configure a port as eligible for dynamic VLAN access?
9. Which feature, offered on some Catalyst switches, places IP phones into their own VLANs without any end-user intervention?
10. Which VTP modes allow an administrator to create or delete VLANs?
1. Round-Robin load-balancing algorithm
2. Building Access
3. 30
4. "dynamic desirable" or "trunk"
5. The 1f is the HSRP group identifier for standby group 31.
6. 802.1x
7. 20 seconds
8. switchport access vlan dynamic
The 'switchport access vlan dynamic' command configures a port as eligible for dynamic VLAN access. Use the following steps to configure a port for dynamic VLAN assignment:
1. Enter interface configuration mode and the port to be configured.
Switch(config)#interface [interface]
2. Set the port to access mode.
Switch(config-if)#switchport mode access
3. Configure the port as eligible for dynamic VLAN access.
Switch(config-if)#switchport access vlan dynamic
NOTE: You must configure the switch as a VMPS client before the switch port can participate in the dynamic VLAN. This is done using the 'vmps server [ipaddress] primary' and 'vmps server [ipaddress]' global configuration commmands to specify the VMPS primary and secondary servers.
