A mall provides security services to customers with a shared appliance. The mall wants separation of management on the shared appliance. Which ASA deployment mode meets these needs?

Cisco ASA's multiple context mode allows a single physical ASA device to be partitioned into multiple virtual devices, each known as a security context. Each context operates as an independent firewall with its own security policies, interfaces, and administration, fulfilling the requirement for separate management and logical isolation for different customers sharing the appliance.

Transparent mode makes the ASA act as a 'bump in the wire' Layer 2 bridge without requiring IP address changes on protected hosts, but it doesn't provide logical separation or separate management contexts for multiple customers.

Routed mode is the default and most common operating mode where the ASA acts as a Layer 3 router, but it manages the entire device as a single firewall instance, not multiple isolated instances for separate customers.

"Multiple zone mode" is not a standard Cisco ASA deployment mode for customer separation; zones are typically used for logical grouping of interfaces within a single firewall instance.
