When selecting an ISR1K with 4 GB RAM for branches, which two software features must it support?

For an ISR1K with 4 GB RAM to be effective in a branch office, it must support core security features. Enterprise Firewall is crucial for basic network perimeter protection, controlling traffic flow, and enforcing security policies. URL filtering is essential for preventing access to malicious or unauthorized websites, enhancing security and productivity. Cisco AMP and AMP Threat Grid, while valuable, typically require more resources than a 4GB ISR1K can efficiently provide for a branch. A vSmart Controller is a control plane component of Cisco SD-WAN and runs on dedicated virtual machines or appliances, not on an ISR1K branch router. Cisco Umbrella DNS Security is a cloud-based service, not a software feature directly running on the ISR1K itself, although the router can be configured to use it.
