NEW QUESTION # 32
One of your customers has the following:
2-Tier L2 Design
* 8325 32x100G Core Switches
* 8360 48x10G RJ-45 Access Switches
* 100G 5M DAC connections between Core and Access
Core Switches = VSX Pairs of 8325 32-port 100G switches (F-B airflow).
Access Switches = VSX Pairs of 8360-48xBaseT switches (F-B airflow).
Each Core Switch pair uses the following for VSX:
* 2 x 100G QSFP28 1M DACs for ISL
* 1 x 100G QSFP28 1M DAC for Keepalive
Each Access Switch pair uses the following for VSX:
* 2 x 100G QSFP28 1M DACs for ISL
* 1 x 10G RJ45 cable for Keepalive
Each Core switch has 29 remaining available 100G QSFP28 interfaces for access switch connectivity.
This solution uses 1x100G QSFP28 5M DAC from each access switch to each core switch.
This solution can scale up to a maximum of14racks using the same subscription rates.
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
