Choose the most suitable technology for the DCI (Data Center Interconnect) when Data Centers are geographically not in the same building:
- A . VSX
- B . ERPS + VRRP
- C . STP
- D . VSF
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.
What is the solution scalability?
- A . Solution can scale to 6 total racks using the same subscription rates.
- B . Solution can scale to 10 total racks using the same subscription rates.
- C . Solution can scale to 4 total racks using the same subscription rates.
- D . Solution can scale to 12 total racks using the same subscription rates.
What is recommended for the routing protocol setup on leaf VSX pairs?
- A . Configure the leaf VSX members to establish neighbor relationships with each other over one of the server subnets
- B . Have the VSX members connect to each spine switch on an L3 VSX LAG and become neighbors with each other and the spine on its subnet
- C . Add a dedicated VLAN to the VSX ISL, assign it a /31 subnet, and run the routing protocol on it
- D . Do not configure the routing protocol to run directly between the leaf VSX members
Which switch model is able to perform microsegmentation?
- A . CX 10000
- B . CX 8325
- C . CX 8400
- D . CX 8360
- E . CX 6400
Aruba CX 6200 are the only switches that support VSF and VSX stacking
- A . True
- B . False
What can be used to encrypt data in flight between untrusted locations?
- A . OSPF authentication
- B . MACSec
- C . GRE tunnels
- D . MD5 encryption
What is one difference between a QSFP28 LC BiDi transceiver and a QSFP28 MPO SR4 transceiver?
- A . The BiDi transceiver uses fewer fiber strands than the SR4 transceiver
- B . The BiDi transceiver supports splitting the bandwidth into multiple lower bandwidth links
- C . The BiDi transceiver requires single-mode fiber, while the SR4 transceiver supports multi-mode
- D . The BiDi transceiver supports lower bandwidth than the SR4 transceiver
Which stacking technology is a dual control plane stacking that is supported by CX switches?
- A . Back Plane Stacking
- B . IRF
- C . Front Plane Stacking
- D . VSX
When collecting information about the Power in your Data Center design you need to take into account (Select two)
- A . The fiber strands that are needed to support the TOR switches
- B . The direction of the airflow
- C . The type of the voltage DC or AC
- D . What voltage is used
Which of the following switches support both Front-to-Back and Back-to-Front airflow? (Select two)
- A . 8400
- B . 8360
- C . 8325
- D . 8320
