質問 # 47
Refer to the exhibit. A WLC is deployed at a branch location to facilitate secure client connectivity.
A network engineer configures one WLAN using WPA2 Personal passphrase and activates ASCII format key to align with company security policies. Which configuration enables client authentication for this WLAN?
正解:A
解説:
WPA2-Personal authenticates clients with a preshared key, not with 802.1X. Cisco documents WPA/WPA2 as supporting multiple authentication methods, including 802.1X and PSK, and specifically states that when PSK is selected, a preshared key or passphrase must be configured.
The configuration element that enables client authentication in this scenario is the PSK ASCII key function represented by option D. On Catalyst 9800 IOS XE, the PSK method is enabled with PSK authentication key management, and the passphrase is defined with security wpa psk set- key {ascii | hex} {0 | 8} password; Cisco's example is security wpa psk set-key ascii 0 test.
Option A disables 802.1X AKM, which is appropriate for Personal mode, but it does not by itself authenticate clients. Option B controls DHCP proxy behavior and has no role in WPA authentication. Option C enables AES for WPA2 encryption, which protects traffic confidentiality but does not supply the authentication secret.

Refer to the exhibit.
An engineer must configure wireless guest networking for a deployment at site A, which requires support for guest VLAN assignment and assignment for wlan guest-network 20. The controller will provide network segregation and restrict access to internal resources. Based on the configuration commands, which action meets the requirements?
正解:A
解説:
The exhibit creates WLAN profileguest-networkwith WLAN ID20and enables web authentication, but it does not yet define the client VLAN or bind the WLAN to a deployable policy. On Catalyst 9800 controllers, the WLAN profile defines SSID and wireless/security characteristics, while thepolicy profiledefines client-facing network policy, including VLAN assignment, AAA, ACLs, and switching behavior. Cisco's web authentication configuration guide states that the policy profile specifies client VLAN, AAA, ACLs, timeout settings, and related policy, and the VLAN is assigned under the policy profile.
The second required object is thepolicy tag, because a policy tag maps the WLAN profile to the policy profile.
Cisco also notes that the default policy tag automatically maps only WLAN IDs1 through 16; WLAN ID17 or highercannot use that default mapping. Since this WLAN is ID 20, a custom policy tag mapping is required.
Mesh bridging, STP, AP group naming, or physical-interface isolation do not complete the Catalyst 9800 WLAN-to-VLAN policy model. Reference topics:Wireless Network Implementation - Catalyst 9800 configuration model, WLAN profiles, policy profiles, policy tags, guest VLAN assignment, and web authentication.
質問 # 49
Which wireless connection occurs when there are no physical obstacles between the receiver and transmitter?
正解:A
解説:
The correct answer isline-of-sight. In RF terminology, line-of-sight describes a wireless path where the transmitting antenna and receiving antenna have an unobstructed visual or RF path between them. Cisco's RF power documentation defines this directly: antennas that can see each other without obstacles between them are considered to be in line of sight. This is especially important in outdoor, bridge, mesh, and point-to-point wireless designs, where buildings, terrain, foliage, or other obstructions can degrade or block the RF path.
The other options describe different RF behaviors.Attenuationis signal loss as RF energy travels through free space, cables, walls, or other materials.Reflectionoccurs when RF energy bounces off a surface such as metal, glass, or concrete, often contributing to multipath.Beamformingis an antenna/transmission technique that focuses RF energy toward a client or receiver to improve signal quality; it is not the condition of having no obstacles. Cisco mesh planning guidance also emphasizes verifying whether a wireless link has clear line of sight before deployment, reinforcing that LOS is a path condition, not a modulation or security feature.
Reference topic:RF Fundamentals - RF propagation, path loss, line-of-sight, obstruction effects, and wireless link planning.
質問 # 50
A network administrator at a marketing company is deploying a Cisco Catalyst 9800 Series Wireless Controller running Cisco IOS XE 17.x. The corporate WLAN named XYZ-Guest supports visitor devices. To address intermittent connectivity issues due to client association limits and short session timeouts, the network administrator must optimize the WLAN to allow more client connections and extend session timeouts for the devices. The administrator must set the maximum number of clients for the XYZ-Guest WLAN to 50 and must set a session timeout to prevent frequent device disconnections. Which two commands must be configured on the controller? (Choose two.)
正解:A、C
解説:
The maximum client association limit is configured under the WLAN to control how many clients can connect to that WLAN. The session timeout is configured under the wireless policy profile to extend the allowed client session duration and reduce frequent disconnections.
質問 # 51
A business is deploying Cisco Catalyst 9100 APs managed by Catalyst 9800 WLCs. The IT team needs policies that adapt based on user identity and device posture and also provide visibility into device activity and location. Which configuration meets these requirements?
正解:B
解説:
To enforce adaptive policies based on user identity, device posture, and provide comprehensive visibility into device activity and location, Cisco recommends integrating Cisco Catalyst Center, Cisco ISE, and Cisco Spaces. Cisco ISE provides identity-based access control and posture assessment, allowing dynamic policy enforcement for users and devices. Mobile device management integration further extends posture checks for endpoint compliance. Cisco Catalyst Center enables real-time assurance and monitoring of network performance, device activity, and service health, while Cisco Spaces provides location analytics and visibility of client devices across the wireless environment.
