NEW QUESTION 58
Is this a guideline for establishing a Virtual Switching Extension (VSX) Inter-Switch Link (ISL) between two ArubaOS-CX switches?
Solution: Reserve the ISL for control plane traffic only.

Yes

Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. VSX Inter-Switch Link (ISL) is a link between the two VSX switches that is used for both data plane and control plane traffic. It is not recommended to reserve the ISL for control plane traffic only, as this would limit the benefits of VSX and create suboptimal traffic forwarding. Therefore, this is not a valid guideline for establishing a VSX ISL between two ArubaOS-CX switches.

NEW QUESTION 59
Does this correctly describe NetEdit’s notification capabilities?
Solution: NetEdlt can send an error link to admins through ServlceNow.

Yes

NetEdit is a network management tool that allows you to configure, monitor, and troubleshoot ArubaOS-CX switches. NetEdit can send notifications of changes in network conditions to other services, such as ServiceNow, using methods that define the service type and credentials. ServiceNow is a cloud-based platform that provides IT service management and digital workflows. NetEdit can send an error link to admins through ServiceNow, which allows them to view the details of the error and take actions to resolve it1. Therefore, this correctly describes NetEdit’s notification capabilities.

NEW QUESTION 60

Solution: Reserve the ISL for control plane traffic only.

Yes

Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. VSX Inter-Switch Link (ISL) is a link between the two VSX switches that is used for both data plane and control plane traffic. It is not recommended to reserve the ISL for control plane traffic only, as this would limit the benefits of VSX and create suboptimal traffic forwarding1. Therefore, this is not a valid guideline for establishing a VSX ISL between two ArubaOS-CX switches.

NEW QUESTION 61
Is this part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) ring?
Solution: Implement Virtual Switching Extension (VSX) on pairs of ERPS switches at the same site. Then combine multiple links between two data centers into VSX LAGs (M-LAGs).

Yes

Implement Virtual Switching Extension (VSX) on pairs of ERPS switches at the same site. Then combine multiple links between two data centers into VSX LAGs (MC-LAGs) is not part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) ring. ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSX LAGs or MC-LAGs are LAGs that span across two VSX nodes and provide load balancing and resiliency. However, VSX LAGs or MC-LAGs are not supported by ERPS because they can create loops in the ring topology. A better way to load share traffic across the links in an ERPS ring would be to use link aggregation groups (LAGs) between two nodes in a ring as long as they are not multi-chassis LAGs (MC-LAGs).

NEW QUESTION 62
Refer to the exhibit.
Refer to the exhibit.

You are adding a VLAN 30, subnet 10.0.30.0/24 to the network shown in the exhibit. (This network is simplified to just the relevant switches for this item.) This subnet belongs in VRF A, and you have added a Layer 3 VLAN 30 interface attached to this VRF on Switch-1. You want to make the services in this VLAN available to devices in 10.1.20.0/24 in VRF B.
Is this part of a valid setup for meeting these requirements?
Solution: Add VRF B as the secondary VRF on VLAN interface 30.

Yes

The solution is incorrect because adding VRF B as the secondary VRF on VLAN interface 30 is not part of a valid setup for meeting these requirements. Adding VRF B as the secondary VRF on VLAN interface 30 would allow devices in VLAN 30 to communicate with devices in VRF B, but not vice versa. Therefore, adding VRF B as the secondary VRF on VLAN interface 30 is not sufficient for meeting these requirements.: https://www.arubanetworks.com/support-services/training-services/data-center-network-specialist/

NEW QUESTION 63
Is this a rule for configuring schedule profiles on an ArubaOS-CX switch?
Solution: If the profile mixes strict priority scheduling with another scheduling algorithm, the strict priority queue must be the highest numbered queue.

Yes

A schedule profile is a feature of ArubaOS-CX that determines the order and service of queues for transmission. A schedule profile must be configured on every interface at all times. The switch supports three scheduling algorithms: Guaranteed Minimum Bandwidth (GMB), Strict, and Strict EQS. Strict scheduling gives absolute priority to a queue over other queues, regardless of the bandwidth allocation. If the profile mixes strict priority scheduling with another scheduling algorithm, the strict priority queue must be the highest numbered queue. Therefore, this is a rule for configuring schedule profiles on an ArubaOS-CX switch, and the correct answer is yes. For more information on schedule profiles and QoS, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet and the QoS Guide for your switch model.

NEW QUESTION 64
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: 51 protected VLANs: 51-100 Ring 1, Instance 2:
control VLAN: 51 protected VLANs: 101-150 Ring 2, Instance 1: control VLAN: 181 protected VLANs: 181-200 Ring 2, Instance 2: control VLAN: 181 protected VLANs: 201-220

Yes

ERPS is a feature of ArubaOS-CX that prevents loops at layer 2 on ring networks1. ERPS uses a protocol called Ring Auto Protection Switching (RAPS) to detect link failures and perform fast traffic switchover1. ERPS supports multiple rings and multiple instances per ring1. Each instance has a control VLAN and one or more protected VLANs1. The control VLAN carries the RAPS PDUs and must be unique per ring1. The protected VLANs are the user traffic VLANs that are protected by ERPS and must be unique per instance1. Based on the exhibit, the design for the control and protected VLANs on the VSX fabric 1 switches is not valid. The control VLAN 51 is used for both instances 1 and 2 on ring 1, which violates the rule that the control VLAN must be unique per ring1. The protected VLANs 51-100 and 101-150 are also overlapping with the control VLAN 51, which violates the rule that the protected VLANs must be unique per instance1. Therefore, this is not a valid design for the control and protected VLANs on the VSX fabric 1 switches, and the correct answer is no. For more information on ERPS and VLANs, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2 and the ERPS Guide for your switch model1.

NEW QUESTION 65
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 l, instance 1:
control VLAN: 1000 protected VLANs: 51-135 Ring 1, Instance 2:
control VLAN: 1000 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1001 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1001 protected VLANs: 201 -220

Yes

Ring l, instance 1: control VLAN: 1000 protected VLANs: 51-135 Ring l,Instance2: control VLAN:
1001 protected VLANs: 136-220 Ring 2, Instance l: control VLAN: 1002 protected VLANs: l8l -200 Ring 2, Instance2: control VLAN: l003 protected VLANs:201 -220 is a valid design for the control and protected VLANs on the VSX fabric l switches for an Ethernet Ring Protection Switching (ERPS) solution. The control VLANs are unique for each ring instance and do not overlap with any protected VLANs. The protected VLANs are also unique for each ring instance and do not overlap with any control VLANs.

NEW QUESTION 66
Your task is to configure an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. Is this statement about EVPN and IPv6 correct?
Solution: IPv6 protocol can be encapsulated in the underlay network’s IPv4 packets.

Yes

IPv6 protocol cannot be encapsulated in the underlay network’s IPv4 packets. EVPN is a protocol that provides layer 2 and layer 3 services over an IP network. It uses VXLAN tunnels to encapsulate Ethernet frames in UDP packets and transport them across the underlay network.
The underlay network can use either IPv4 or IPv6 protocol, but it must match the protocol used by the VXLAN tunnels. The statement is false because it implies that IPv6 protocol can be encapsulated in IPv4 packets, which is not possible.

NEW QUESTION 67
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

Yes

Enhanced Transmission Selection (ETS) is a network scheduling algorithm that allows the switch to assign different priority and bandwidth values to different traffic classes. 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 devices. 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.

NEW QUESTION 68
Is this a use case for disabling split-recovery mode on ArubaOS-CX switches in a Virtual Switching Extension (VSX) fabric?
Solution: You want to prevent any possibility of a split brain situation from occurring if the keepalive link fails some time after the ISL.

Yes

Split-recovery mode is a feature of ArubaOS-CX that prevents traffic loss when the ISL goes out-of-sync and keepalive subsequently fails12. This can happen if the ISL is restored after a failure but the VSX nodes are not synchronized. Split-recovery mode enables the secondary switch to restore its VSX LAGs after 10 keepalive packets are missed, approximately 10 seconds after keepalive goes down2. This avoids a split brain situation where both switches act as primary and forward traffic independently, causing loops and duplicate packets1. Therefore, disabling split-recovery mode is not a use case for preventing split brain situations, and the correct answer is yes. For more information on split-recovery mode and VSX, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet3 and the Virtual Switching Extension (VSX) Guide for your switch model2.

NEW QUESTION 69
Is this a rule for configuring schedule profiles on an ArubaOS-CX switch?
Solution: With the exception of a single strict priority queue, all queues must use the same scheduling algorithm.

Yes

With the exception of a single strict priority queue, all queues must use the same scheduling algorithm is a rule for configuring schedule profiles on an ArubaOS-CX switch. A schedule profile defines how traffic is scheduled across different queues on an interface. Each queue can have one of three scheduling algorithms: strict priority (SP), weighted round robin (WRR), or weighted fair queuing (WFQ). However, only one queue can have SP, and all other queues must have either WRR or WFQ1.

NEW QUESTION 70
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.

Yes

NEW QUESTION 71
You are using NetEdit to manage AruDaOS-CX switches. You want to deploy a standard config to the switches, but need the config to include a few device-specific settings such as hostname and IP address.
Is this what you should do?
Solution: Inside a configuration plan, right-click any device-specific parameters and modify the parameter per-device.

Yes

Inside a configuration plan, right-click any device-specific parameters and modify the parameter per-device is what you should do if you want to use NetEdit to manage ArubaOS-CX switches and deploy a standard config to the switches, but need the config to include a few device-specific settings such as hostname and IP address. This approach allows you to edit any parameter value for individual devices within a configuration plan without affecting other devices or creating separate plans1.

NEW QUESTION 72
Is this part of the process for using NetEdit to update firmware on ArubaOS-CX switches?
Solution: Use a firmware update plan to manage both updating the Image on selected devices and reboot.

Yes

Use a firmware update plan to manage both updating the Image on selected devices and reboot is part of the process for using NetEdit to update firmware on ArubaOS-CX switches. NetEdit is a tool that provides automation and analytics for managing ArubaOS-CX switches. A firmware update plan is a type of plan that allows you to update the firmware image on one or more switches and reboot them as needed.

NEW QUESTION 73
Refer to the exhibits. Is this how the switch handles the traffic?

Solution: A broadcast arrives with a VLAN 10 tag on 1/1/1 on Switch-1. Switch 1 drops the frame.

Yes

Based on the exhibits, Switch-1 has a trunk port on 1/1/1 that allows VLANs 10 and 20. Switch-2 has an access port on 1/1/2 that belongs to VLAN 10. Switch-3 has an access port on 1/1/3 that belongs to VLAN 20. If a broadcast arrives with a VLAN 10 tag on 1/1/1 on Switch-1, Switch-1 does not drop the frame. Instead, Switch-1 forwards the frame to all ports that belong to VLAN
10, which includes the trunk port 1/1/2 and the access port 1/1/4. Switch-2 receives the frame on its access port 1/1/2 and forwards it to all ports in VLAN 10, which includes the access port 1/1/5.
Switch-3 does not receive the frame because it is not in VLAN 10. Therefore, this is not how the switch handles the traffic, and the correct answer is no.

NEW QUESTION 74
Does this correctly describe how the Virtual Switching Extension (VSX) fabric reacts to various component failure scenarios?
Solution: The ISL goes down, and after a few seconds, the keepalive link goes down too. Switch-
1 and Switch-2 remains up.
The Split-recovery mode is enabled. In this case the secondary switch first shutdowns and then enables SVis.

Yes

The Virtual Switching Extension (VSX) fabric is a high availability solution that provides industry- leading performance and simplicity for campus and data center networks. When the ISL goes down, and after a few seconds, the keepalive link goes down too, the VSX fabric reacts differently depending on the split-recovery mode setting. If the split-recovery mode is enabled, the secondary switch shuts down all its SVIs and waits for the ISL to come back up. If the split- recovery mode is disabled, both switches keep their SVIs up and continue to forward traffic.
Therefore, this does not correctly describe how the VSX fabric reacts to various component failure scenarios.

NEW QUESTION 75
Is this something that NetEdit 2.0 does after it discovers a switch?
Solution: It enables the switch REST API Interface, if disabled.

Yes

It enables the switch REST API interface, if disabled is not something that NetEdit 2.0 does after it discovers a switch. NetEdit 2.0 is a tool that provides configuration management and validation for ArubaOS-CX and ArubaOS-Switch devices. NetEdit 2.0 can discover switches using various methods such as IP range scan, LLDP scan, CSV import, etc. However, NetEdit 2.0 cannot discover or communicate with switches that have their REST API interface disabled because NetEdit 2.0 relies on REST API calls to interact with switches.

NEW QUESTION 76
Does this correctly describe Network Analytics Engine (NAE) limitations on ArubaOS-CX switches?
Solution: Different switches have different limitations for the number of NAE scripts, monitors, and agents supported.

Yes

Different switches have different limitations for the number of NAE scripts, monitors, and agents supported is a correct description of Network Analytics Engine (NAE) limitations on ArubaOS-CX switches. NAE is a feature that provides automation and analytics for managing ArubaOS-CX switches. NAE scripts are scripts that run on switches and collect data from various sources. NAE monitors are rules that define conditions and actions for NAE agents. NAE agents are instances of NAE scripts and monitors that run on switches. Different switches have different limitations for the number of NAE scripts, monitors, and agents supported depending on their hardware resources1.

NEW QUESTION 77
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).

Yes

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) is a correct positioning of ArubaOS-CX switches in the data center. The Aruba CX 6300 switches are designed for data center leaf roles, and they support advanced features such as VSX, EVPN, and PFC that enable high performance, scalability, and resiliency for data center networks.

NEW QUESTION 78
Does this correctly describe NetEdit’s notification capabilities?
Solution: NetEdit notifies admins of errors using Its Internal email server.

Yes

NetEdit is a network management tool that allows you to configure, monitor, and troubleshoot ArubaOS-CX switches. NetEdit can send notifications of changes in network conditions to other services, such as email, using methods that define the service type and credentials. However, NetEdit does not use its internal email server to send notifications. NetEdit requires an external SMTP server to send email notifications, and the SMTP server address, port, username, and password must be configured in the email method. Therefore, this does not correctly describe NetEdit’s notification capabilities.
