For a Cisco UCS 2208XP with the number of links illustrated in Exhibit 3, which four options are valid in the Chassis/FEX Discovery global policy? (Choose four.)
A. 1 Link
B. 2 Link
C. 3 Link
D. 4 Link
E. 8 Link
F. Platform Min
G. Platform Max
Correct Answer: ABDG
Explanation/Reference:
Explanation: Exhibit 3 is shown below:
Here we see that there are 4 links between the IOM and the fabric interconnects. Cisco UCS Manager cannot discover any chassis that is wired for fewer links than are configured in the chassis/FEX discovery policy. For example, if the chassis/FEX discovery policy is configured for 4 links, Cisco UCS Manager cannot discover any chassis that is wired for 1 link or 2 links.
The following table provides an overview of how the chassis/FEX discovery policy works in a multi-chassis Cisco UCS domain: Table 1 Chassis/FEX Discovery

1link between IOM and fabric interconnects
Chassis is discovered by Cisco UCS Manager and added to the Cisco UCS domain as a chassis wired with 1 link.
Chassis connections and servers cannot be discovered by Cisco UCS Manager and are not added to the Cisco UCS domain.
Chassis connections and servers cannot be discovered by Cisco UCS Manager and are not added to the Cisco UCS domain.
Chassis connections and servers cannot be discovered by Cisco UCS Manager and are not added to the Cisco UCS domain. Chassis connections and servers cannot be discovered by Cisco UCS Manager and are not added to the Cisco UCS domain.
2links between IOM and fabric interconnects
Chassis is discovered by Cisco UCS Manager and added to the Cisco UCS domain as a chassis wired with 1 link.
After initial discovery, reacknowledge the chassis and Cisco UCS Manager recognizes and uses the additional links.

If the IOM has 4 links, the chassis is discovered by Cisco UCS Manager and added to the Cisco UCS domain as a chassis wired with 4 links. If the IOM has 8 links, the chassis is not fully discovered by Cisco UCS Manager.
8 links between IOM and fabric interconnects
Chassis is discovered by Cisco UCS Manager and added to the Cisco UCS domain as a chassis wired with 1 link.
After initial discovery, reacknowledge the chassis and Cisco UCS Manager recognizes and uses the additional links. Chassis is discovered by Cisco UCS
