You are involved in a 2-Tier L2 Data Center Design with the following details:
• CX 8325 100G Core Switches
• CX 10000 48-P 25G Access Switches
• 100G SR4 Optical connections between Core and Access
In this design, both the Core Layer and Access Layer consist of pairs of switches configured in VSX for HA.
Core Switches = VSX Pairs of CX 8325 32-port 100G switches (B-F airflow) Each pair uses:
• 2 x 100G QSFP28 1M DACs for ISL
• 1 x 100G QSFP28 1M DAC for Keepalive
• 2 x 100G QSFP28 SR4 Optic to each access switch Each Core switch has 13 available 100G QSFP28 interfaces.
What is the maximum number of racks supported by this design?
- A . Solution can scale to 7 total racks using the same subscription rates.
- B . Solution can scale to 14 total racks using the same subscription rates.
- C . Solution can scale to 8 total racks using varying subscription rates.
- D . Solution can scale to 16 total racks using the same subscription rates.
In a multi-AS underlay design
- A . All spine switches are in the same AS while each leaf (VSX pair if used) are in their own AS
- B . Every spine and every leaf is in their own AS
- C . All spine and leaf switches are in one AS and the border leaf is in separate AS
- D . Every spine is in their own AS while all leaf switches in one AS
Which of the following statements is true about HPE and HPE Aruba Networking breakout cables for high-speed ports?
- A . QSFP56 -> 4x 50 GbE QSFP28
- B . QSFP56 -> 2x 100 GbE QSFP28
- C . QSFP56 -> 8x 10 GbE SFP+
- D . QSFP56 -> 4x 25 GbE SFP28
In MMF OM3 fiber type and SFP28 LC SR transceiver option.
What is the maximum distance supported by this setup?
- A . Up to 50 meters
- B . Up to 70 meters
- C . Up to 500 meters
- D . Up to 700 meters
PVLAN (Private VLAN) defines three types of VLANs under the same SVI
- A . Primary VLAN, Isolated VLAN and Customer VLAN
- B . Secondary VLAN, Isolated VLAN and Provider VLAN
- C . Primary VLAN, Isolated VLAN and Community VLAN
- D . Provider VLAN Service VLAN and QinQ VLAN
In which situation do you need to select switches with a back-front (BF) airflow?
- A . The switches are core switches in a dedicated rack with their ports facing the cold aisle
- B . The switches are ToR switches which will have the port side facing the opposite way as server ports
- C . The switches are middle of the rack switches with their ports facing the cold aisle
- D . The switches are ToR switches which will have the port side facing the same way as server ports
In VSX, the ISL (InterSwitch Link):
- A . Can be indirectly connected
- B . Must be directly connected
- C . Can be used for keep alive communications
- D . They must be routed links
Which of the following are deemed as Post-installation handover tasks
- A . Project budget details
- B . Enable monitoring of new systems
- C . RFP
A customer currently has a three-tier architecture in which aggregation switches are the default gateways. Pairs of aggregation switches use VRRP. You are migrating to an L2 two-tier architecture in which the core switches are the default gateways.
How should you migrate the default gateway functionality?
- A . Use a DHCP server to assign servers new gateway IP addresses, which are configured on the new core switches
- B . Configure VSX active gateway on the new core switches using the current default gateway IP address as the virtual IP and a new virtual MAC address
- C . Add the core switches to the aggregation switches’ VRRP groups and use VRRP to fail over to the new switches
- D . Configure VSX active gateway on the new core switches using a new default gateway IP address as the virtual IP and the existing VRRP MAC for the virtual MAC address
Which CX switch model supports ERPS/VSX DCI?
- A . 5130
- B . 8100
- C . 8325
- D . 2930F
