Online Access Free HPE7-A04 Practice Test

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. There is a requirement for multicast traffic to be supported across all data center rooms and fabrics. What needs to be done?

• A.Establish a separate data center interconnect fabric for multicast traffic only
• B.Change the design to use one fabric per site
• C.Change the design to extend a single fabric across all rooms and both sites
• D.Use HPE Aruba CX switches' selective split horizon feature

How many SFP28 port-groups do Aruba 8325 CX switches have?

• A.4 port-groups of 8 ports each
• B.One port-group of 48 ports
• C.4 port-groups of 12 ports
• D.12 port-groups of 4 ports each

In a multi-AS underlay design

• A.Either eBGP or iBGP for underlay routing within a leaf and spine topology will work
• B.This is a wrong design for routing protocol for the underlay
• C.You must use iBGP for underlay routing within a leaf and spine topology
• D.You must use eBGP for underlay routing within a leaf and spine topology

In L3 spine and leaf design

• A.You don't need to use spanning tree for loop prevention
• B.You need to use TRILL to prevent loops
• C.Spanning Tree is always needed since Spine and Leaf is only there to improve performance
• D.Since all Spine switches are connected to each other, EVPN is needed in this design

2-Tier L2 Design
* 6400 100G Core Switches
* 8320 48-P 10G RJ45 Access Switches
* 40G DAC connections between Core and AccessCore Switches = VSX Pairs of 6400 switches (each with 2 x 12-port QSFP28 100G modules) Each pair uses:
* 2 x 1M 100G DAC for ISL
* 1 x 1M 100G DAC for Keepalive
* 2 x 5M 40G DAC to each access switch
Each Spine switch has 5 x 100G interfaces available.
This solution could scale to a maximum of:

• A.10 total racks using same subscription rates
• B.7 total racks using same subscription rates
• C.12 total racks using same subscription rates
• D.15 total racks using same subscription rates
