HPE7-A04 Aruba Certified Data Center Architect Exam Practice Test

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.

What is the upper limit for spine switches with leaf HPE Aruba CX 8360-48Y6C v2 using 100 or 40 GbE Leaf-to-spine port speed (when using 2 uplink ports for VSX)?

You have a customer who wants 3:1 oversubscription and has a CX switch with 24 ports, and each port operates at 25 Gbps edge ports. What is the expected uplink speed?

What is the maximum number of spines (when using 2 uplink ports for VSX) for CX 8325-48Y8C with Leaf-to-spine port speed 40 or 100 Gbps?

You are planning a leaf and spine topology for a data center. The campus is in a different building; the customer wants to connect the campus network directly to the data center network. To which data center switch or switches do you connect the campus core switches?

Aruba CX 6200 are the only switches that support VSF and VSX stacking

In which situation do you need to select switches with a back-front (BF) airflow?
