Final answer:

To see all passive interfaces on a Cisco device, you use the 'show ip protocols' command, although the 'show running-config' command mentioned in the options can also reveal passive interfaces by listing them under the routing protocol configurations.

Step-by-step explanation:

The command used to see all passive interfaces on a network device, such as a router, is usually device-specific. However, for devices such as Cisco routers that run IOS (Internetwork Operating System), the command is show ip protocols. This command displays the status of all configured IP routing protocols, which includes a list of interfaces that are set as passive. In most cases, passive interfaces are configured under routing protocols like OSPF, EIGRP, or RIP to prevent them from sending or receiving routing updates on those interfaces. To directly answer the given multiple-choice question, there isn't an explicit command named show passive-interfaces, but looking at 'show running-config' can indeed reveal the passive interfaces as they would be listed under the routing protocol configurations.
