Which local DHCP pools that are configured on an autonomous IOS AP will properly work and lease IP addresses to the wireless clients without using the "ip helper-address" command?
Click on the arrows to vote for the correct answerA. B. C. D.
When a wireless client connects to an autonomous IOS AP and requests an IP address from the DHCP server, the AP can act as a DHCP server and provide IP addresses to the clients from its own local DHCP pool. However, there are certain conditions that must be met for this to work properly:
Given these conditions, the answer to the question is B. Only the pool configured for the VLAN assigned to the SSID where the wireless clients are connected will properly work and lease IP addresses to the wireless clients without using the "ip helper-address" command. This is because the AP will only act as a DHCP server for the VLAN(s) where the wireless clients are connected, and each SSID is typically mapped to a specific VLAN. Therefore, if you have multiple SSIDs with different VLAN assignments, you will need to configure a separate DHCP pool for each VLAN/SSID combination.
Answer A is incorrect because the native VLAN is typically used for management traffic and is not usually associated with any SSID or wireless clients. Answer C is incorrect because not all of the configured local DHCP pools may be applicable to the VLAN(s) where the wireless clients are connected. Answer D is also incorrect because static routing has no direct impact on the ability of the AP to act as a DHCP server for its local DHCP pools.
