1. 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 underlay routing protocol between each data center room?

6. You want to implement distributed firewall policies that micro-segment VM-to-VM traffic, including within the VLAN and same host. The VMs should be able to send traffic on permitted TCP ports, but other traffic should be dropped (hosts are isolated).

What are two requirements? (Select two.)

7. You are designing an overlay solution for two Data Centers based on the Aruba CX platform. Each Data Center has two rooms and each room is its own fabric.

What is the underlay routing protocol run within each room?

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

10. What resiliency technologies relate to Default Gateway redundancy requirement on CX switches?

11. Loopback addresses are very useful for troubleshooting and for device management.

What is true about the loopback interfaces?

12. In one of the spine and leaf designs, VMware vSphere is used including VMware NSX. OSPF is used for routing protocol across the spine and leaf topology.

What do you need to consider in this design? (Select three)

13. In Aruba CX 8325 switches, what is true about port-groups?

14. What is a use case for a two-tier L2 design for a dedicated data center?

15. You are recommending HPE Aruba CX switches to a service provider for a Metro Ethernet solution.

Which technology is the customer likely to require to allow each customer to stretch multiple VLANs across the Metro Ethernet line?

16. 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?

17. Which management solution for HPE Aruba Networking CX switches integrates tightly with VMware?

18. In VSX, the ISL (InterSwitch Link):

19. You are setting up a single EVPN VXLAN fabric for a data center. A customer has one ESXi cluster in racks 1-3 that uses VLAN 10 for VMs in subnet 10.1.10.0/24. The customer has another ESXi cluster in racks 4-6 that uses VLAN 10 for VMs in subnet 10.2.10.0/24.

Which is correct?

20. In Spine and Leaf Design that involves the following:

• 8360 12-P 100G Spine Switches

• 8360 48-P 10G RJ45 Leaf Switches

• 100G SR4 Optical connections between Spine and Leafs Spine Switches = 8360 12-port 100G QSFP28 (F-B airflow)

Each Spine Switch uses:

• 1 x 100G QSFP28 SR4 Optic to each Leaf switch

Each Leaf Switch uses:

• 1 x 100G QSFP28 SR4 Optic to each Spine switch

• 2 x 100G 1M DAC for ISL

• 1 x 10G RJ45 for Keepalive

Each Spine switch has 4 available 100G QSFP28 interfaces.
