ERPS (Ethernet Ring Protection Switching):

• Is not supported on CX 6400 switch series
• Prevents broadcast storms and implements fast-traffic switchover on a network where there are loops
• Does not prevent broadcast storms but implements fast-traffic switchover on a network where there are loops
• Is not supported on CX 8400 switch series

Which stacking technology is a dual control plane stacking that is supported by CX switches?

• Back Plane Stacking
• IRF
• Front Plane Stacking
• VSX

You are designing overlay solutions 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 routing protocol used for EVPN advertisement within each room?

• OSPF
• iBGP
• eBGP
• EIGRP

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

• Can have transceivers that operate at 100 Gbps
• Each port-group can have different speed transceivers
• All port-groups transceivers need to be of the same speed
• Must have the same speed transceivers within a port-group

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?

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

Which switch model is able to perform microsegmentation?

• CX 10000
• CX 8325
• CX 8400
• CX 8360
• CX 6400

What is the solution scalability?

• Solution can scale to 6 total racks using the same subscription rates.
• Solution can scale to 10 total racks using the same subscription rates.
• Solution can scale to 4 total racks using the same subscription rates.
• Solution can scale to 12 total racks using the same subscription rates.

You created a formal proposal and quote for a customer's data center network refresh. What is some other support information that you should include? (Select two)

• A list of IP addresses that you plan to configure on the switches
• No need to include any of these as the proposal is not the place to educate the customer on them
• HPE Aruba networking recommends including a block diagram with proposals
• A list of VLANs that you plan to configure on the switches

You want to configure your border leaf switches to leak routes between an overlay VRF named “dc1” and a VRF named “campus,” which connects to the campus core. You also want to leak routes between an overlay VRF named “dc2” and the campus VRF. “dc1” should not be able to communicate with “dc2.” Which is a valid design for the VRFs’ IPv4 route-targets?

• vrf dc1, import = 1:1, export = 1:99; vrf dc2, import = 1:2, export = 1:99; vrf campus, import = 1:99, export = 1:1, 1:2
• vrf dc1, import = 1:1, export = 1:1; vrf dc2, import = 1:2, export = 1:2; vrf campus, import = 1:1, 1:2, 1:99, export = 1:99
• vrf dc1, import = 1:99, export = 1:1; vrf dc2, import = 1:99, export = 1:2; vrf campus, import = 1:1, 1:2 export = 1:99
• vrf dc1, import = 1:1, export = 1:1; vrf dc2, import = 1:1, export = 1:1; vrf campus, import = 1:1, export = 1:99

In defining availability requirements for applications and services, the applications that directly impact health and safety are called

• Mission-Critical Applications
• Team-Critical Applications
• Business-Critical Applications
• Life-Critical Applications
