HPE7-A04 Exam - Topic 4 Question 8 Discussion

Actual exam question for HP's HPE7-A04 exam
Question #: 8
Topic #: 4
[All HPE7-A04 Questions]

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 of 14 racks using the same subscription rates.

I disagree, I think it could go beyond 14 with the right setup.

I’m leaning towards 14 as well, but I wish I had reviewed the details on how the VSX pairs impact the total number of racks.

I feel like the answer could be 16, but I can't quite remember the specifics of how the connections limit the scalability.

I think we practiced a similar question where the scaling was based on the number of DAC connections. If I recall correctly, it was around 14 racks.

I remember something about the maximum scalability being tied to the number of available interfaces, but I'm not entirely sure how that translates to the number of racks.

Okay, let's see. The key information I need to focus on is the number of available 100G QSFP28 interfaces on the core switches and the maximum number of racks this solution can scale up to. I think I can figure this out.
