Question No. 1

Refer to the exhibit.

which shows the topology tot an Ethernet Ring Protection Switching (ERPS) solution.

Is this a valid design for the control and protected VLANs on the VSX fabric 1 switches?

Solution: Ring 1, instance 1:

control VLAN: 1000protected VLANs: 51-135 Ring l,Instance2:

control VLAN: 1001 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1000 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1003 protected VLANs: 201 -220

AYes

BNo

Show Answer

Correct Answer: B

Ring 1, instance 1: control VLAN: 1000protected VLANs: 51-135 Ring l,Instance2: control VLAN: 1001 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1000 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1003 protected VLANs: 201 -220 is not a valid design for the control and protected VLANs on the VSX fabric 1 switches for an Ethernet Ring Protection Switching (ERPS) solution. The control VLANs must be unique for each ring instance and must not overlap with any protected VLANs. In this design, the control VLAN 1000 is used for both ring 1 instance 1 and ring 2 instance 1, which can cause conflicts and errors.Also, the protected VLANs 181-220 are used for both ring instances on ring 2, which can cause loops and traffic duplication2.

Question No. 2

AtubaOS-CX switches are acting as Virtual Extensible LAN (VXLAN) Tunnel Endpoints (VTEPs) WITHOUT Ethernet VPN (EVPN).

Does this correctly describe how the VTEPs handle VXLAN traffic forwarding?

Solution: VTEPs that use headend replication forward unicasts with unknown destination MAC addresses as unicast packets to each VTEP in the same VNl.

AYes

BNo

Show Answer

Correct Answer: A

VTEPs that use headend replication forward unicasts with unknown destination MAC addresses as unicast packets to each VTEP in the same VNI is a correct description of how the VTEPs handle VXLAN traffic forwarding. Headend replication is a method of replicating VXLAN packets at the ingress VTEP instead of using multicast routing.The ingress VTEP sends a copy of the VXLAN packet to each egress VTEP that belongs to the same VNI using unicast tunnels1.

Question No. 3

Is this a use case for implementing Enhanced Transmission Selection (ETS) on an ArubaOS-CX switch?

Solution: to enable the switch to assign the correct priority and bandwidth to traffic that it transmits to servers

AYes

BNo

Show Answer

Correct Answer: A

Enhanced Transmission Selection (ETS) is a network scheduling algorithm that allows the switch to assign different priority and bandwidth values to different traffic classes1. This can be useful for transmitting traffic to servers that have different requirements for latency, jitter, or throughput. For example, ETS can prioritize voice or video traffic over data traffic, or allocate more bandwidth to backup or replication traffic.ETS is configured using the Data Center Bridging Exchange (DCBx) protocol, which advertises the configuration to peer devices2. Therefore, implementing ETS on an ArubaOS-CX switch is a valid use case for enabling the switch to assign the correct priority and bandwidth to traffic that it transmits to servers.

Question No. 4

Can you attach this type of ArubaOS-CX interface to a VRF?

Solution: a GRE tunnel interface

AYes

BNo

Show Answer

Correct Answer: A

A GRE tunnel interface is a virtual interface that can encapsulate different network layer protocols inside point-to-point or point-to-multipoint links over an IP network1. It can be assigned an IP address and attached to a VRF.A VRF allows multiple instances of a routing table to co-exist within the same router2.By attaching a GRE tunnel interface to a VRF, you can isolate the traffic of that tunnel from other tunnels and routing domains2.

Question No. 5

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.

AYes

BNo

Show Answer

Correct Answer: B

Virtual Extensible LAN (VXLAN) enables multiple isolated Layer 3 domains, each with its own routing table, to share a physical network is not a way that a data center technology can help meet requirements for multi-tenancy. Multi-tenancy is the ability to provide logical separation and isolation of network resources for different tenants or customers on a shared physical infrastructure. VXLAN is a feature that provides Layer 2 extension over Layer 3 networks using UDP encapsulation.VXLAN does not enable multiple isolated Layer 3 domains, but rather multiple isolated Layer 2 domains, each with its own VNI1.
