The Cisco Switch Selector is an interactive web-based tool designed to help customers choose the appropriate Cisco switch based on specific use cases, deployment needs, or feature sets. It allows users to filter and compare across multiple Catalyst and Meraki switch models based on parameters like PoE support, port count, form factor, and stackability. Hence, option A accurately describes its purpose.

Cisco Meraki licensing includes several benefits, one of which is full access to firmware updates and cloud-managed security features. These updates are continuously deployed and available as part of the active license, ensuring customers always run the most secure and updated version of their software without additional cost. Thus, option D is correct.

A typical small branch office, usually with fewer than 25 users, often requires simplified, efficient networking solutions. One of the common needs is to reduce infrastructure complexity while still supporting essential services such as routing, firewalling, switching, and voice.

Cisco documents related to branch infrastructure design state that for small branches, integrated services routers (like ISR 1000/4000 series) are recommended because they combine multiple services—such as WAN connectivity, security (firewall/IPS), VPN, wireless LAN controller functionality, and voice support—into a single platform. This reduces hardware footprint, simplifies management, and ensures better performance at the edge.

Therefore, integrating multiple network functions into a single device fulfills a typical requirement of a small branch, making option A the most accurate.

Physical stacking in Meraki MS switches is only supported within the same model family and series. The MS350-48 and MS350-24X belong to the same MS350 series and are explicitly listed as stack-compatible in Cisco Meraki documentation. Stacking between different series (e.g., MS225 and MS350 or MS225 and MS425) is not supported. MS120 switches do not support physical stacking at all. Therefore, option B is the correct and only valid choice.

Cisco Meraki's architecture uses an out-of-band control plane. If a device loses connection to the Meraki Cloud, client data traffic continues to flow locally and normally, while management and monitoring features are paused until connectivity is restored. This behavior is explicitly confirmed by Cisco documentation stating that during cloud disconnect, user traffic is unaffected and only configuration/monitoring stops.

Cisco DNA Assurance is a foundational service in Cisco DNA Center that provides real-time analytics, insights, and guided remediation. It focuses on the performance and reliability of the network, aligning closely with the concept of SLAs (Service Level Agreements). DNA Assurance ensures the infrastructure is functioning as designed and enables IT to verify that network services meet user and application requirements. Hence, the correct answer is A.
