Which of the following policies are you most likely to implement to ensure that all three UCS devices are discovered?

Most likely, you will implement a 1-Link Chassis Discovery Policy to ensure that all three Cisco Unified Computing System (UCS) devices are discovered in this scenario. The link chassis discovery policy that is configured on Cisco UCS Manager specifies the minimum number of links that a UCS chassis must have to the fabric interconnect in order to be automatically discovered and added to the UCS domain. If a UCS chassis has fewer than the minimum number of links specified by the policy, the chassis will be neither discovered nor added to the UCS domain by Cisco UCS Manager. The two Cisco fabric interconnects in this scenario, FEX 1 and FEX 2, are connected together. UCS 1 has a one-link connection to FEX 1. UCS 2 has a two-link connection to FEX 1. UCS 3 has a one-link connection to FEX 2. A 1-Link Chassis Discovery Policy in this scenario would cause Cisco UCS Manager to discover and add UCS 1, UCS 2, and UCS 3 to the UCS domain because each of those devices has at least one link to the fabric interconnect.
There are five link chassis discovery policies that are supported by Cisco UCS Manager: 1-Link Chassis Discovery Policy, 2-Link Chassis Discovery Policy, 4-Link Chassis Discovery Policy, 8-Link Chassis Discovery Policy, and Platform-Max Discovery Policy. A 2-Link Chassis Discovery Policy in this scenario would cause Cisco UCS Manager to discover and add UCS 2 to the UCS domain because UCS 2 is the only device that has at least two links to the fabric interconnect. However, a 1-Link Chassis Discovery Policy will cause UCS 2 to be discovered and added as a chassis with only one link. In order to have Cisco UCS Manager recognize and use the other link between UCS 2 and the fabric interconnect, you would need to reacknowledge the chassis in Cisco UCS Manager after the initial discovery has been completed.
A 4-Link Chassis Discovery Policy would not cause Cisco UCS Manager to discover the UCS devices in this scenario. For a 4-Link Chassis Discovery Policy to discover any of the UCS devices in this scenario, at least one of those devices would need to have a minimum of four links to the fabric interconnect. For example, if UCS 3 had four or more links to the fabric interconnect in this scenario and Cisco UCS Manager was configured with a 4-Link Chassis Discovery Policy, only UCS 3 would be discovered and added to the UCS domain.
An 8-Link Chassis Discovery Policy would not cause Cisco UCS Manager to discover the UCS devices in this scenario. For an 8-Link Chassis Discovery Policy to discover any of the UCS devices in this scenario, at least one of those devices would need to have a minimum of eight links to the fabric interconnect. None of the UCS devices in this scenario are connected with more than two links to the FEX devices.
