Cisco Exam 300-610 Topic 1 Question 77 Discussion

Actual exam question for Cisco's 300-610 exam

Question #: 77
Topic #: 1

Refer to the exhibit. A Cisco engineer is configuring a customer scenario with 2 x MDS 9000 switches 24 x UCS B200M6 blade servers. UCS 64S4 Fabric Interconnect in end-host mode and 3 x UCS 5108 server chassis with 2408 Fabric Extenders The engineer installs 6 x SQL Server 2019 on all blades and then notices that there are read and write latencies What is the best way to balance the utilization across the shared ports?

AEnable 'Only dedicate rate mode

BChange the assigned speed to 8 Gbps Auto.

CSet 4 Gbps performance buffers

DDisable restrictions on oversubscription ratios

Show Suggested Answer

Suggested Answer: D

When restrictions on oversubscription ratios are disabled, the bandwidth allocation among the shared ports is proportionate to the configured speed. (If the configured speed is auto, then bandwidth is allocated assuming a speed of 4 Gbps.) For example, if you have three shared ports configured at 1, 2, and 4 Gbps, then the allocated bandwidth ratio is 1:2:4. In Cisco SAN-OS Release 3.0 and later (or when restrictions on oversubscription ratios are enabled), port bandwidths are allocated in equal proportions, regardless of port speed, so, the bandwidth allocation for the same three ports mentioned in the example would be 1:1:1.

Hmm, this question seems pretty tricky. We're dealing with a complex Cisco networking setup with MDS switches, UCS, and SQL Server. Latency issues are always a headache in these kinds of environments.
