質問 # 28
Refer to the exhibit. A network engineer is designing a high availability SSO on a Cisco Catalyst
9800- 40 WLC with multi-LAG network redundancy on two Catalyst 9300 switches. The LAG requirements are: ?Each LAG must be connected to a single switch. ?Different VLANs must be assigned to different LAGs. ?The controller must learn the identity of partners that can support LAG capabilities in each port. ?When any active LAG ports fail, a standby LAG port must provide redundancy. Which protocol must be used for the port channel on the interface to meet the design requirements?
正解：B
解説：
The design requirements specify a multi-LAG configuration where each LAG connects to a single switch, different VLANs are assigned to different LAGs, the controller must dynamically learn partner LAG capabilities per port, and standby ports provide redundancy upon active port failure.
These requirements collectively point to IEEE 802.3ad LACP (Link Aggregation Control Protocol) as the correct protocol. LACP is the industry-standard IEEE protocol that enables dynamic negotiation of LAG membership between endpoints -- the WLC and each Catalyst 9300 switch exchange LACP PDUs (LACPDUs) to discover port capabilities, negotiate bundle membership, and monitor link status. LACP supports active and passive port states where active ports initiate negotiation and passive ports respond, and it provides the standby port mechanism through its hot-standby capability for link redundancy within the bundle. The requirement to 'learn the identity of partners that can support LAG capabilities' is the defining characteristic of LACP's standardized PDU exchange mechanism.

A hospital has a Cisco Catalyst 9800 Series Wireless Controller in an SSO solution deployed in the primary data center. The hospital plans to increase redundancy in the wireless environment.
Management decides to deploy an extra Catalyst 9800 WLC offsite to another data center on a different subnet. A WAN link connects the data centers with a firewall at both ends. Which two design approaches must the engineer take to ensure that the APs can fail over? (Choose two.)
正解：A、D
解説：
For APs to be able to fail over between a primary SSO pair in one data center and a standalone WLC in a remote data center connected via WAN with firewalls, two design requirements must be met. First, a mobility tunnel must be created between the wireless controllers (Option A). The mobility tunnel enables the controllers to exchange mobility control messages, peer information, and eventually AP context when failover occurs. Without the mobility tunnel, the remote WLC is not recognized as a valid failover target by the APs through the mobility domain. Second, UDP ports 16666 and 16667 must be open through the firewalls between the controllers (Option D).
UDP port 16666 is used for mobility control traffic and UDP port 16667 is used for mobility data traffic -- both must be permitted through the firewalls at both data centers for the mobility tunnel to establish and function.
質問 # 30
An engineer is designing a wireless network in a historic building that has large rooms and ornate wall coverings. Which approach must be considered first when placing access points?
正解：B
解説：
When designing a wireless network for any environment, including a historic building with ornate wall coverings and aesthetic constraints, RF coverage must always be considered first when placing access points. RF coverage is the fundamental requirement -- without adequate signal strength throughout the space, no other design objective can be met. The engineer must first determine AP locations that provide the required signal strength and coverage to all areas before addressing aesthetics, overlap calculations, or interference mitigation. In a historic building specifically, the ornate wall coverings and dense construction materials may cause unexpected signal attenuation, making it even more important to model RF coverage before committing to AP positions.
質問 # 31
A network engineer is deploying Cisco 9130I APs on multiple Cisco Catalyst 9800-80 WLCs with Cisco Catalyst Center. The engineer must enable Cisco AI Analytics and location analytics to use the RRM features to automatically manage the WLC RF profiles. Which type of license must be used on Cisco Catalyst Center?
正解：A
解説：
Cisco Catalyst Center's AI-driven network management capabilities -- including AI Analytics, AI- Enhanced RRM (Radio Resource Management), location analytics (DNA Spaces integration), and automated RF profile management -- are exclusively available under the Catalyst Advantage license tier. The Advantage tier builds upon the Essentials tier and adds access to the full suite of AI/ML- powered assurance and optimization features. Specifically, AI-Enhanced RRM leverages machine learning models trained on historical RF telemetry to predict and prevent RF issues, dynamically adjust channel and power assignments, and automate RF profile selection -- capabilities that cannot be activated without the Advantage license. Location analytics through Catalyst Center integrates with Cisco Spaces to provide real-time client location tracking, asset tracking, and spatial analytics.
質問 # 32
A network engineer must design a new wireless solution for a company, but the budget can only stretch to include a single Cisco 9800-40 WLC. The company requires high availability between the WLC and the core switch in the event of a cable failure. The WLC must dynamically manage port redundancy and perform load balancing between APs transparently. Which design approach must the engineer take to meet the requirements?
正解：A
解説：
Link Aggregation Group (LAG) is the correct design approach for a single Cisco 9800-40 WLC that requires high availability between the WLC and the core switch in the event of a cable failure. LAG combines multiple physical ports on the WLC into a single logical channel, providing both redundancy (traffic automatically redistributes across remaining links when one fails) and load balancing (traffic is distributed across all active links). Importantly, LAG operates transparently to AP management - APs see a single logical uplink regardless of which physical port their traffic traverses. With a single WLC, Multi-LAG (Option B) is not applicable - Multi-LAG is a feature of the Catalyst 9800 that allows multiple separate LAG bundles for different network connections, typically used with SSO pairs. LACP (Option C) is the protocol used to negotiate LAG member links - it is the mechanism within LAG, not an independent design approach. PAgP (Option D) is a Cisco proprietary alternative to LACP for port aggregation but the question asks for the design approach, which is LAG.
