An engineer must register a fixed network on a Cisco Umbrella platform. Which two actions must be performed when adding a new public IP address? (Choose two.)

When adding a fixed network to Cisco Umbrella, entering its public IP address is essential as it allows Umbrella to identify and associate incoming DNS requests with that specific network for policy enforcement.

Installing the Umbrella root certificate is typically required for full SSL inspection or client-side deployments, not as one of the initial steps for merely registering a fixed network for DNS-based protection.

Configuring the DNS security settings is a subsequent step where policies are defined *after* the network is registered and DNS is pointed to Umbrella, not an initial action for adding the network itself.

For Cisco Umbrella to provide DNS-layer security, all devices within the fixed network must be configured to point their DNS settings to Umbrella's globally distributed DNS servers, directing all DNS queries through the platform.

Cisco Umbrella functions as a DNS security service, not a DHCP server; therefore, pointing DHCP to Umbrella platform DHCP servers is an incorrect action.
