NEW QUESTION # 34
After the administrator of an enterprise deploys a DHCP server, employees complain that their clients cannot obtain IP addresses from the DHCP server. Which of the following may cause this problem?
Answer: B,D
Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* DHCP Configuration Issues:
* Option C: The DHCP function is disabled by default on Huawei devices. If the administrator forgets to enable it, clients cannot receive IP addresses.
* Option D: DHCP uses broadcast messages, which do not traverse routers. If the clients and DHCP server are on different subnets, a DHCP relay agent must be configured.
* Other Options:
* Option A: Multiple DHCP servers can coexist as long as their IP address pools do not overlap.
This is unlikely to cause the problem.
* Option B: STP does not affect DHCP operations unless it delays port activation, which is uncommon in this scenario.

Roaming technology is typically used on a large WLAN to ensure that STA (station) services are not interrupted when STAs move between coverage areas of different APs.
Answer: B
Explanation:
Comprehensive and Detailed In-Depth Explanation:
* Wireless LAN (WLAN) roaming allows mobile devices (STAs) to move seamlessly between different APs without dropping connections.
* Types of WLAN Roaming:
* Layer 2 roaming # STAs move between APs in the same subnet without IP address changes.
* Layer 3 roaming # STAs move across different subnets, requiring IP address reconfiguration (handled via DHCP or tunneling).
* Since roaming prevents service interruption in large WLAN deployments, the statement is true.
