Q69. Is this a requirement for implementing Priority Flow Control (PFC) on an ArubaOS-CX switch interface?
Solution: configuring a DCBX application priority on the interface

Q70. Is this a guideline for establishing a Virtual Switching Extension (VSX) Inter-Switch Link (ISL) between two ArubaOS-CX switches?
Solution: Use the same speed on every link In the ISL.

Q71. Is this correct positioning of AtubaOS-CX switches in the data center?
Solution: Aruba CX 6300 switches are an appropriate choice for leaf switches in a leaf-spine topology that uses Virtual Extensible LAN (VXLAN) with Ethernet VPN (EVPN).

Q72. Does this correctly describe NetEdit’s notification capabilities?
Solution: NetEdlt can send an error link to admins through ServlceNow.

Q73. Is this a way that a data center technology can help meet requirements for multi-tenancy?
Solution: Virtual Extensible LAN (VXLAN) enables multiple isolated Layer 3 domains, each with its own routing table, to share a physical network.

Q74. Can you attach this type of ArubaOS-CX interface to a VRF?
Solution: A physical interface using Layer 2 mode

Q75. Does this correctly describe the ArubaOS-CX architecture?
Solution: The Aruba0S-CX Network Analytics Engine (NAE) helps admins to manage multiple Aruba0S-CX switches together using familiar CLI commands.

Q76. Does this correctly describe the ArubaOS-CX architecture?
Solution: The ArubaOS-CX time-series database helps to support network analytics and troubleshooting.

Q77. A data center has a three-tier topology with ArubaOS-CX switches at each layer, is this a use case for implementing Virtual Switching Extension (VSX) at the core?
Solution: The aggregation layer operates at Layer 2 only, and the core provides Layer 2 and Layer 3 functions.

Q78. A customer’s servers use ISCSI, and they send data and storage traffic on the same pair of I OGbE links. Is this a best practice for supporting the ISCSI requirements?
Solution: Set up dedicated switches to connect to iSCSl arrays. Connect top of rack (ToR) switches, which will support both data and storage traffic, to those dedicated switches.

Q79. You want to use NetEdit to configure an AtubaOS-CX switch.
Is this a minimum requirement for setting up communications between the switch and NetEdit?
Solution: Make sure that the SSH server is enabled.

Q80. Does this correctly describe routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN?
Solution: IMET routes advertise the MAC addresses that the VTEP has learned locally in a VXLAN.

Q81. Does this correctly describe how Network Analytics Engine (NAE) agents work?
Solution: Agents collect data every minute and send the data to a centralized SNMP server in SNMP traps.

Q82. Is this a requirement for implementing Priority Flow Control (PFC) on an ArubaOS-CX switch interface?
Solution: configuring trust of Cos on the interface

Q83. Switch-1 and Switch-2 are AruDaOS-CX switches, which are part of a Virtual Switching Extension (VSX) fabric. Switch-2 is the primary member. Switch-2 experiences a power failure while Switch-1 remains up. Switch-2’s power recovers, and Switch-2 reboots.
Is this one of the things that happens when Switch-2 finishes booting?
Solution: Switch-1 downloads its MAC forwarding table from Switch-2.

Q84. You are configuring Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Is this a guideline for configuring timers?
Solution: The wait to restore timer (WTR) Is set in units of minutes; you can set it to prevent frequent topology changes due to a link going up and down.

Q85. Does this correctly describe how the Virtual Switching Extension (VSX) fabric reacts to various component failure scenarios?
Solution: The keepalive goes down, ISL link remains up. Switch-1 and Switch-2 remains up. The Split-recovery mode is disabled. In this case the secondary switch shutdowns Svls.
