In L3 Spine and Leaf design, which answer is correct?
- A . Leaf switches connect to other leaf switches
- B . Each leaf switch connects to each spine switch
- C . Each spine switch connects to all other spine switches in a full mesh
- D . Leaf switches connect to only one spine switch
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?
- A . 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
- B . 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
- C . 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
- D . 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 your design, you have six racks each with a pair of VSX Leaf switches and two Spine switches.
How many P2P leaf-to-spine addresses are there?
- A . 12
- B . 96
- C . 24
- D . 48
In a Spine and Leaf Design with the following specs:
• 8400 100G Spine Switches
• 8360 48-P 10G RJ45 Leaf Switches
• 100G DAC connections between Spine and Leafs Spine Switches = 8400 with 12 QSFP28 ports (F-B airflow) Each Spine Switch uses:
• 1 x 100G QSFP28 5M DACs to each Leaf switch Each Leaf Switch uses:
• 1 x 100G QSFP28 5M DACs to each Spine switch
• 2 x 100G 1M DAC for ISL
• 1 x 10G RJ45 for Keep alive
Each Spine switch can support up to 48 available 100G QSFP28 interfaces.
What is the scalability for this solution?
- A . Solution can scale to 24 total racks using the same subscription rates.
- B . Solution can scale to 6 total racks using the same subscription rates.
- C . Solution can scale to 12 total racks using the same subscription rates.
- D . Solution can scale to 48 total racks using the same subscription rates.
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?
- A . iBGP
- B . eBGP
- C . OSPF
- D . IS-IS
How many Aruba 100G QSPF28 LC ER4L 40KM SMF Transceivers are allowed on Aruba CX 8325?
- A . Twelve Transceivers
- B . Four Transceivers
- C . None
- D . Eight Transceivers
What is true about clients located in isolated VLAN?
- A . By default, The switch allows ARP traffic between clients in isolated VLAN
- B . Endpoints in an isolated VLAN are not allowed to communicate with each other
- C . Isolated VLAN is always a member of Service VLAN
- D . Isolated VLAN is a VLAN in QinQ
HPE Aruba Networking switch selector is accessible from
- A . Intangi IRIS design tool
- B . Aruba Support Portal
- C . HPE PSNow tools
- D . From NetEdit management tool
Which of these protocols carries commands for reading from/writing to storage over a TCP/IP session?
- A . RDMA
- B . iSCSI
- C . NVMeoF-RDMA
- D . FCoE
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 . Change the design to extend a single fabric across all rooms and both sites
- B . Change the design to use one fabric per site
- C . Use HPE Aruba CX switches’ selective split horizon feature
- D . Establish a separate data center interconnect fabric for multicast traffic only
