質問 # 60
A network engineer is designing a new wireless network. The network must include these requirements: ?optimized performance ?avoid interference ?availability in high-density areas ?roaming Which two approaches must be taken? (Choose two.)
正解：A、E
解説：
The design requirements -- optimized performance, interference avoidance, high-density support, and roaming capability -- collectively point to a dual-band strategy using narrow channel widths.
For 5 GHz operation (Option A), 20 MHz channels are the correct choice for high-density and campus- scale deployments. The 5 GHz band has significantly more non-overlapping channels compared to 2.4 GHz (up to 24 non-overlapping 20 MHz channels in UNII-1, UNII-2, and UNII-3), enabling a robust channel reuse plan with minimal co-channel interference and excellent roaming cell separation.

An enterprise is using wireless as the main network connectivity for clients. To ensure wireless network availability, two standalone controllers are installed in the head office. APs are connected to the controllers using a round-robin approach to load balance the traffic. After a power cut, the wireless clients disconnect while roaming. An engineer tried eping from the controller but fails. Which protocol needs to be allowed between the networks that the controllers are installed?
正解：A
解説：
When eping (EoIP ping) fails between two Cisco Wireless LAN Controllers, it indicates that the data path of the mobility tunnel is blocked. In Cisco AireOS wireless networks, the mobility data path uses IP Protocol 97 (EtherIP - Ethernet-over-IP encapsulation) for tunneling client traffic between the anchor and foreign controllers. This is distinct from the control path, which uses UDP port 16666. When the mobility data path (IP Protocol 97) is blocked by a firewall or ACL between the two controllers ' networks, eping will fail because eping specifically tests the EoIP data encapsulation path. After a power cut, when clients disconnect and attempt to roam between APs on different controllers, the mobility tunnel must be operational for session continuity. If IP Protocol 97 is blocked, the mobility data plane cannot function, causing client disconnections during inter-controller roaming events. The other IP protocols listed (67, 77, 87) are not used for Cisco WLC mobility tunneling. Reference: WLSD Study Guide - Mobility Tunnel Data Path, IP Protocol 97 (EtherIP), eping Command and Troubleshooting.
質問 # 62
A customer has a centralized wireless deployment with N+1 high availability and few open authentication SSIDs configured. After failover, all APs are broadcasting all SSIDs, but the clients are assigned IP addresses from a different subnet. The WLANs on both WLCs are configured with the same dynamic interfaces. Which feature must be incorporated in the wireless design of the second controller?
正解：A
解説：
VLAN Select is a feature that allows for the dynamic assignment of clients to different VLANs from a pool based on various criteria, such as load balancing or location. In a centralized wireless deployment with N+1 high availability, if clients are receiving IP addresses from a different subnet after failover despite the WLANs being configured with the same dynamic interfaces, the issue is that the second controller ' s WLAN interface mapping resolves to a different VLAN or DHCP scope. VLAN Select ensures that client VLAN assignment is consistent regardless of which controller the client connects to, preventing the subnet change behavior observed during failover. Without VLAN Select, even identically named dynamic interfaces on two WLCs may map to different VLANs if the underlying switch configuration differs. RF Protocol (Option A) controls radio parameters. AP Groups (Option B) control SSID and VLAN assignments per AP cluster. AAA Override (Option D) allows RADIUS servers to assign per-user VLANs, which requires authentication - but these SSIDs use open authentication. Reference: WLSD Study Guide - N+1 High Availability Design, VLAN Select Feature, Consistent Client VLAN Assignment Across Controllers.
質問 # 63
A company is upgrading its wireless infrastructure and is in a state of transition. Some parts of the company's building still run on the legacy WLC. The new WLC is not located at the same site as the legacy WLC. The company requires seamless client inter-controller roaming between the new WLC and the legacy WLC, with no disruptions. Both WLCs are separated by firewalls. Which troubleshooting command validates that the mobility control packets between the WLCs can be sent and received?
正解：D
解説：
The command 'debug mobility handoff enable' is used to validate the mobility control packets between Wireless LAN Controllers (WLCs). This command enables debugging of the handoff process, which is critical for ensuring seamless client roaming between controllers. When WLCs are separated by firewalls, it is essential to confirm that mobility control packets can traverse these firewalls without being dropped or rejected. The 'debug mobility handoff enable' command allows network administrators to monitor the handoff process in real time and identify whether mobility PDUs are being exchanged successfully. If mobility control packets are being blocked by the firewall, this debug output will show failures in the handoff sequence. This command directly validates bidirectional mobility traffic flow, making it the correct troubleshooting tool for the scenario described.
質問 # 64
During a post-deployment site survey, issues are found with non-Wi-Fi interference. What should the engineer use to identify the source of the interference?
正解：D
解説：
Cisco Spectrum Expert is a dedicated spectrum analysis tool designed to identify and analyze non- Wi-Fi interference sources at Layer 1. During a post-deployment site survey, it can detect interference from various devices such as cordless phones, Bluetooth devices, microwave ovens, video cameras, and other unlicensed RF emitters. The tool provides a visual representation of the RF environment across the frequency spectrum, allowing engineers to pinpoint the exact source of interference and characterize it by duty cycle, frequency, and interference pattern. A network analysis module (Option A) operates at Layer 2 and above, unable to detect non-802.11 RF emissions.
