Refer to the exhibit. A Cisco engineer is configuring a data center design scenario with Cisco MDS 9000 Series Switches. The cut-through routing mode is chosen for improved read operation performance. Each iSCSI host requires access to storage through the IPS module. First, the engineer configures the TCP tuning parameters as enabled SACK, the maximum bandwidth of 1 Gbps, buffer size of 4096, keepalive timeout at 1s, and enables Path MTU. Then, the engineer must set the QoS of the ISCSI link. What is the maximum QoS value that must be set for the ISCSI session?

Question

Accepted Answer

D. 63 On Cisco MDS 9000 Series Switches using an IPS module for iSCSI, the QoS value for an iSCSI session is typically configured using a DSCP (Differentiated Services Code Point) value. DSCP values range from 0 to 63, allowing for granular prioritization; setting the QoS value to 63 corresponds to the highest possible DSCP value, ensuring optimal performance for critical storage traffic.

Answer

A. 1 A QoS value of 1 represents a very low priority and would not be optimal for iSCSI storage traffic.

Answer

B. 3 A QoS value of 3 represents a low priority and would not be optimal for iSCSI storage traffic.

Answer

C. 5 A QoS value of 5, while slightly higher, is still a relatively low priority and not the maximum or typically recommended for critical iSCSI traffic.
