In a high availability setup where both primary and secondary gateway clusters are present, APs are typically designed to connect to the primary cluster. If the APs are equally split between the primary and secondary, this may indicate that some APs cannot reach the primary cluster due to connectivity issues or reachability constraints, thus falling back to the secondary cluster.

Based on the criteria provided for wireless guest users, the correct user role configuration must allow internet access, only allow access to public DNS servers, deny access to all internal networks except for any DHCP server, and place the Wi-Fi guests on VLAN 555. The ACLs must permit services necessary for basic internet access (such as DNS and DHCP) and block access to internal networks.

Option A satisfies these criteria with the following configurations:

• user-role "WiFi-guest": This defines the role for Wi-Fi guests.
• access-list session dhcp-acl: This applies the access list that likely permits DHCP, which is necessary for guests to obtain an IP address.
• access-list session dns-acl: This applies the DNS access list, which likely restricts guests to using public DNS servers.
• access-list session internal-networks: This applies the internal networks access list, which denies access to internal networks.
• vlan 555: This sets the VLAN for Wi-Fi guests to 555.

Options B, C, and D are incorrect because they includeaccess-list session allowallwhich would permit all traffic, contradicting the requirement to deny access to all internal networks.

The Modulation and Coding Scheme (MCS) used by wireless stations is directly affected by the signal-to-noise ratio (SNR) and the frequency band. Higher SNR can lead to higher MCS values, which means better data rates. The frequency band can affect MCS due to different channel characteristics, such as the presence of interference and propagation properties, which are factors in determining data rates.

Multi-Pre-Shared Key (MPSK) with ClearPass is the recommended solution for a scenario where the IT Helpdesk needs to configure IoT devices to connect to a single SSID using unique PSKs. MPSK allows for the use of different PSKs on the same SSID, and ClearPass enables the management of these unique keys efficiently.
