In Routing design for a two-tier topology between the data center and other parts of the network, select the best option from below
- A . You should not use VSX LAGs for these connections
- B . Don’t use Layer 3 links
- C . Establish point-to-point links using individual /29 subnets
- D . Set up each link as an L3 interface or routed-only port (ROP)
Depending on a switch’s role in the topology, the demands on various tables differ. Several HPE Aruba CX switch models support different profiles, each of which optimizes the correct table for a switch with the corresponding role:
- A . L3 Aggregates profile allocates more space to the support more overlay host entries table compared to leaf switches
- B . L3 Aggregates profile allocates more space to the routing table compared to L3 core profile
- C . L3 Aggregates profile allocates more space to the ARP/ND table compared to L3 core profile
- D . L3 Aggregates profile allocates more space to the routing table compared to Spine switch
In L3 spine and leaf design
- A . Spanning Tree is always needed since Spine and Leaf is only there to improve performance
- B . You need to use TRILL to prevent loops
- C . You don’t need to use spanning tree for loop prevention
- D . Since all Spine switches are connected to each other, EVPN is needed in this design
In L3 Spine and Leaf design OSPF routing, which switches can be ABRs and connect your network to a WAN provider?
- A . Leaf switches that act as centralized routers for the overlay
- B . Leaf switches that act as distributed routers for the overlay
- C . Spine switches
- D . Border leaf switches
If you need to demo the proposed solution you should only use certified Aruba demo portal only
- A . True
- B . False
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.
- A . 12
- B . 14
- C . 16
- D . 18
In a multi-tenant Data Center
- A . VRF offers Layer 3 isolation for the tenants
- B . MSTP offers Layer 2 isolation along with loop prevention
- C . VRF offers Layer 2 isolation for the tenants
- D . VLANs offer Layer 3 isolation for the tenants
You need to design a network that supports transmitting RDMA traffic over multiple IP hops.
Which protocols must the switches support? (Select all that apply.)
- A . ETS
- B . IP ECN
- C . PFC
- D . QCN
Mention two disadvantages of the End-of-Row or Middle-of-Row switches in Data Center design
- A . More equipment
- B . Higher latency for rack-to-rack traffic within the row
- C . Longer, more complex cabling within the row
- D . Lower port density and less scalable
You have a data center with 99.9% availability requirements.
How many hours of downtime (unplanned) is allowed to meet this availability requirement?
- A . 6.8 hours
- B . 3.4 hours
- C . 8.6 hours
- D . 8.8 hours
