質問 # 73
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.
- A. Yes
- B. No
正解：A
解説：
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.
質問 # 74
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
- A. Yes
- B. No
正解：A
解説：
Priority Flow Control (PFC) is a feature of ArubaOS-CX that eliminates packet loss due to congestion on a network link1. PFC uses IEEE 802.1Qbb standard to pause traffic on a per-priority basis1. PFC can be configured to operate in symmetric or asymmetric mode1. Symmetric mode applies PFC to both the receiving and sending of pause frames1. Asymmetric mode applies PFC to either the receiving or sending of pause frames1. To configure PFC on an interface, you need to enable flow control with a priority value and configure a DCBX application priority on the interface1. A DCBX application priority maps a traffic class to a priority group and enables the switch to negotiate PFC parameters with the peer device1. Therefore, this is a requirement for implementing PFC on an ArubaOS-CX switch interface, and the correct answer is yes. For more information on PFC and DCBX, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2 and the QoS Guide for your switch model1.
質問 # 75
Is this part of the process for using NetEdit to update firmware on ArubaOS-CX switches?
Solution: Upload firmware images to the NetEdit firmware repository.
- A. Yes
- B. No
正解：A
解説：
Uploading firmware images to the NetEdit firmware repository is part of the process for using NetEdit to update firmware on ArubaOS-CX switches1. NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1. It also provides a firmware repository where you can store firmware images for different switch models and versions1. You can use NetEdit to upload firmware images to the repository and then deploy them to the switches1.
質問 # 76
The architect designs a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). The architect needs to select the type of Integrated Routing & Bridging (IRB) for the solution.
Is this statement about the IRB type true?
Solution: In the Asymmetric IRB egress VTEPs bridge the traffic to the destination networks.
- A. No
- B. Yes
正解：A
解説：
In the Asymmetric IRB egress VTEPs bridge the traffic to the destination networks is not a true statement about the IRB type for a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). Asymmetric IRB is a method of routing traffic between different VXLAN segments using a centralized gateway. In this method, ingress VTEPs route the traffic to the gateway VTEP using a Layer 3 VNI, and egress VTEPs route the traffic to the destination networks using a Layer 2 VNI1.
質問 # 77
Is this how you should position switches in the ArubaOS-CX portfolio for data center networks?
Solution: Deploy Aruba 83xx switches as core switches for very large three-tier data center networks.
- A. Yes
- B. No
正解：A
解説：
Deploying Aruba 83xx switches as core switches for very large three-tier data center networks is how you should position switches in the ArubaOS-CX portfolio for data center networks. The Aruba 83xx switches are designed for data center spine or core roles, and they provide high performance, scalability, and resiliency. They can support very large three-tier data center networks with up to 512 leaf switches using VSX2.
質問 # 78
You plan to use multi-protocol BGP to implement dynamic VRF route leaking on an ArubaOS-CX switch.
Is this a rule for the setup?
Solution: You cannot leak multicast routes.
- A. No
- B. Yes
正解：A
質問 # 79
An ArubaOS-CX is \ssmq DCBX on Interface 1/1/1. You enter this command:
show dcbx interface 1/1/1
Is this where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX?
Solution: in the Enhanced Transmission Selection (ETS) Local advertisement section
- A. No
- B. Yes
正解：A
解説：
In the Enhanced Transmission Selection (ETS) Local advertisement section is not where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX on an ArubaOS-CX switch interface. The ETS Local advertisement section shows the priority groups and bandwidth allocation that the switch advertises to the CNA, but it does not show whether the CNA has accepted them or not. To see whether the CNA has accepted the application priorities advertised with DCBX, you need to look at the Application Priority Local advertisement section, which shows the application protocol identifier (APPID) and priority values that the switch advertises to the CNA, and compare them with the Application Priority Remote advertisement section, which shows the APPID and priority values that the CNA advertises to the switch1.
質問 # 80
Does this correctly describe NetEdit's notification capabilities?
Solution: NetEdit notifies admins of errors using Its Internal email server.
- A. No
- B. Yes
正解：A
質問 # 81
Refer to the exhibits.
Is this how the switch handles the traffic?
Solution: A frame with destination MAC address, 00:50:56:15:16:28, arrives with a VLAN 10 tag on 1/1/1 on Switch-1. Switch-1 encapsulates the frame with VXLAN and an IP header destined to 192.168.1.2.
- A. No
- B. Yes
正解：A
質問 # 82
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.
- A. No
- B. Yes
正解：A
質問 # 83
Is this part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) solution?
Solution: Implement Virtual Switching Extension (VSX) on pairs of ERPS switches at the same site.
- A. Yes
- B. No
正解：A
解説：
Implementing Virtual Switching Extension (VSX) on pairs of ERPS switches at the same site is part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) solution. VSX allows two switches to act as a single logical device and provide active-active forwarding across both switches. This way, traffic can be load balanced across all links in the ERPS ring without creating loops1.
質問 # 84
Refer to the exhibit.
Switch-1, Switch-2, and the router run OSPF on LAG 100, which is a Layer 3 LAG. Does this correctly explain how to control how core-to-access traffic Is forwarded?
Solution: To reduce the amount of traffic sent over the ISL between Switch-1 and Switch-2. enable Equal Cost Multi Path (ECMP) on both Switch-1 and Switch-2.
- A. No
- B. Yes
正解：A
質問 # 85
Refer to the exhibits.
Is this how the switch-1 handles the traffic?
Solution: A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN 10, except the incoming interface. It encapsulates the broadcast with VXIAN and sends it to 192.168.1.3, out not 192.168.1.2.
- A. No
- B. Yes
正解：A
解説：
A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN 10, except the incoming interface. It encapsulates the broadcast with VXLAN and sends it to 192.168.1.3, but not 192.168.1.2 is not a correct explanation of how the switch handles the traffic. Switch-1, Switch-2, and Switch-3 are ArubaOS-CX switches that use VXLAN and EVPN to provide Layer 2 extension over Layer 3 networks. VXLAN is a feature that uses UDP encapsulation to tunnel Layer 2 frames over Layer 3 networks using VNIs. EVPN is a feature that uses BGP to advertise multicast information for VXLAN networks using IMET routes. Switch-1 receives a broadcast in VLAN 10, which belongs to VNI 5010. Switch-1 forwards the frame on all interfaces assigned to VLAN 10, except the incoming interface, as per normal Layer 2 switching behavior. However, Switch-1 does not encapsulate the broadcast with VXLAN and send it only to 192.168.1.3, which is Switch-2's loopback interface, but rather replicates the broadcast, encapsulates each broadcast with VXLAN, and sends the VXLAN traffic to both 192.168.1.2 and 192.168.1.3, which are Switch-3's and Switch-2's loopback interfaces respectively.
質問 # 86
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.
- A. No
- B. Yes
正解：A
解説：
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.
質問 # 87
You ate using NetEdit to manage AruDaOS-CX switches. You want to deploy a standard conflg 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: Instead of using a standard configuration plan to deploy the configuration, create an auto config plan that uses scripts.
- A. Yes
- B. No
正解：A
解説：
Instead of using a standard configuration plan to deploy the configuration, create an auto config plan that uses scripts 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. An auto config plan is a type of plan that allows you to use scripts to customize the configuration for each switch based on variables such as serial number, MAC address, or user-defined parameters1.
質問 # 88

Solution: Automated configuration of Layer 3 MP-BGP protocol on leaf switches
- A. No
- B. Yes
正解：A
質問 # 89
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.
- A. Yes
- B. No
正解：A
解説：
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.
質問 # 90
Refer to the exhibit.
Switch-1, Switch-2, and the router run OSPF on LAG 100, which is a Layer 3 LAG. Does this correctly explain how to control how core-to-access traffic Is forwarded?
Solution: To reduce the amount of traffic sent over the ISI between Switch-1 and Swltch-2. enable active forwarding on LAG 100 on both Switch-1 and Switch-2.
- A. Yes
- B. No
正解：A
解説：
To reduce the amount of traffic sent over the ISL between Switch-1 and Switch-2, enable active forwarding on LAG 100 on both Switch-1 and Switch-2 is a correct explanation of how to control how core-to-access traffic is forwarded. Switch-1, Switch-2, and the router run OSPF on LAG 100, which is a Layer 3 LAG. Active forwarding is a feature that allows a switch to select one link as active and one link as standby for each direction of traffic in a LAG. Enabling active forwarding on LAG 100 on both Switch-1 and Switch-2 would reduce the amount of traffic sent over the ISL by sending traffic over only one link instead of both1.
質問 # 91
Can you attach this type of ArubaOS-CX interface to a VRF?
Solution: a layer 2 VLAN
- A. No
- B. Yes
正解：A
解説：
A layer 2 VLAN is a single broadcast domain that works on the data link layer1. It cannot be assigned an IP address or attached to a VRF. A VRF requires a layer 3 interface that works on the network layer and can perform routing between different VLANs2. A layer 2 VLAN can only communicate within itself, not with other VLANs or routing domains1.
質問 # 92
Refer to the exhibit.
You need to set up an ArubaOS-CX switch to implement Virtual Extensible LAN (VXLAN) WITHOUT Ethernet VPN (EVPN). The exhibit Indicates which servers should be part of the same VXLANs and the desired VNls for the VXLANs. Assume that the network is already configured to permit each ArubaOS-CX switch to reach each other switch's loopback interface.
Is this part of the process for setting up VXLAN to meet the requirements?
Solution: On Switch-1, set 192.168.1.3 as a peer IP address in the VNI 5020 context.
- A. Yes
- B. No
正解：A
解説：
On Switch-1, set 192.168.1.3 as a peer IP address in the VNI 5020 context is part of the process for setting up VXLAN to meet the requirements of enabling servers to be part of the same VXLANs and VNIs as shown in the exhibit. Switch-1, Switch-2, and Switch-3 are ArubaOS-CX switches that use VXLAN to provide Layer 2 extension over Layer 3 networks without EVPN. VXLAN is a feature that uses UDP encapsulation to tunnel Layer 2 frames over Layer 3 networks using VNIs. To set up VXLAN without EVPN on Switch-1, you need to do the following steps:
Configure loopback interfaces with IP addresses on each switch
Configure VLAN interfaces with IP addresses on each switch
Configure VXLAN interfaces with VNIs on each switch
Configure peer IP addresses for each VNI on each switch
Configure static routes or dynamic routing protocols to enable reachability between loopback interfaces On Switch-1, setting 192.168.1.3 as a peer IP address in the VNI 5020 context means that Switch-1 can send and receive VXLAN traffic for VNI 5020 to and from Switch-2, which has the loopback interface with IP address 192.168.1.3.
質問 # 93
Is this part of the process for using NetEdit to update firmware on ArubaOS-CX switches?
Solution: Create a conformance test to check that the firmware matches the desired version.
- A. Yes
- B. No
正解：A
解説：
Creating a conformance test to check that the firmware matches the desired version is part of the process for using NetEdit to update firmware on ArubaOS-CX switches1. NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1. It also provides a conformance feature that lets you create tests to verify that the switches comply with your desired configuration and firmware settings1. You can use NetEdit to create a conformance test to check that the firmware matches the desired version and then run it on the switches1.

質問 # 94
You enter this command on an ArubaOS-CX switch:
Switch# show erps status ring 1
Is this what the specified status means?
Solution: The status is Idle, which means that the ring is up and fully connected with the RPL port blocked.
- A. No
- B. Yes
正解：A
解説：
The status is Idle, which means that the ring is up and fully connected with the RPL port blocked is not what the specified status means for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Idle is one of the possible statuses for an ERPS ring instance, but it indicates that the ring is not operational and no port is blocked. This can happen when the ring is not configured properly or when there is a miscommunication between the nodes1.
