質問 # 43
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.
- A. No
- B. Yes
正解：A
解説：
The Virtual Switching Extension (VSX) fabric is a high availability solution that provides industry-leading performance and simplicity for campus and data center networks1. 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 up2. If the split-recovery mode is disabled, both switches keep their SVIs up and continue to forward traffic2. Therefore, this does not correctly describe how the VSX fabric reacts to various component failure scenarios. Reference: https://www.arubanetworks.com/assets/tg/TB_VSX.pdf

- A. No
- B. Yes
正解：A
質問 # 45
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.
- A. No
- B. Yes
正解：A
質問 # 46
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.
- A. No
- B. Yes
正解：A
解説：
Agents do not collect data every minute and send the data to a centralized SNMP server in SNMP traps. NAE is a feature that provides network operators with distributed analytics for faster troubleshooting and resolution of network-impacting issues1. Agents are scripts that run on ArubaOS-CX switches and collect data from various sources, such as CLI commands, REST APIs, or syslog messages1. Agents can also define conditions and actions based on the collected data1. Agents do not send the data to a centralized SNMP server, but store it locally on the switch1. Agents can also send alerts to external systems, such as email servers or syslog servers, but not in SNMP traps1. The statement is false because it incorrectly describes how NAE agents work.
質問 # 47
Is this a best practice when positioning ArubaOS-CX switches in data center networks?
Solution: Deploy Aruba CX 83xx switches as data center spine switches.
- A. No
- B. Yes
正解：B
質問 # 48
You are configuring Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Is this a guideline for configuring timers?
Solution: The hold off timer causes ERPS switches to delay unblocking a failed link after the link is restored. This can be useful to prevent frequent topology changes.
- A. No
- B. Yes
正解：B
解説：
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 has two timers that control the protection switching mechanism: guard timer and hold off timer1. The guard timer prevents false switching caused by delayed or lost RAPS PDUs1. The hold off timer causes ERPS switches to delay unblocking a failed link after the link is restored1. This can be useful to prevent frequent topology changes due to link flapping or network instability1. Therefore, this is a guideline for configuring timers for ERPS, and the correct answer is yes. For more information on ERPS and timers, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2 and the ERPS Guide for your switch model1.
質問 # 49
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 # 50
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.
- A. No
- B. Yes
正解：A
質問 # 51
You are configuring Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Is this a guideline for configuring timers?
Solution: The guard interval is set in units of seconds and is used to prevent frequent topology changes due to a link going up and down.
- A. No
- B. Yes
正解：A
解説：
The guard interval is set in units of seconds and is used to prevent frequent topology changes due to a link going up and down is not a guideline for configuring timers for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. The guard interval is set in units of milliseconds, not seconds, and it is used to prevent false ring failures due to short link outages or flapping1.
質問 # 52
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 a route with this command: ip route 10.1.20.0/24 vlan20 vrf A
- A. No
- B. Yes
正解：A
解説：
Adding a route with this command: ip route 10.1.20.0/24 vlan20 vrf A is not part of a valid setup for meeting these requirements. This command would add a static route for 10.1.20.0/24 in VRF A, but it would not be able to reach VLAN 20 on Switch-2 because Switch-2 does not have a VLAN interface for VLAN 20 in VRF A. To make the services in VLAN 30 available to devices in 10.1.20.0/24 in VRF B, you need to use inter-VRF routing or route leaking between VRF A and VRF B on Switch-11.
質問 # 53
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.
- A. No
- B. Yes
正解：B
解説：
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.
質問 # 54
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. No
- B. Yes
正解：B
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 # 55
Does this correctly describe Network Analytics Engine (NAE) limitations on ArubaOS-CX switches?
Solution: You can run NAE with VSX, but only the primary VSX member will actually run agents during normal operation.
- A. No
- B. Yes
正解：B
解説：
Network Analytics Engine (NAE) is a built-in analytics framework for network assurance and remediation on ArubaOS-CX switches. NAE allows monitoring, troubleshooting, and proactive network management using scripts and agents. Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. You can run NAE with VSX, but only the primary VSX member will actually run agents during normal operation. The secondary VSX member will only run agents if the primary member fails or is rebooted1. Therefore, this correctly describes NAE limitations on ArubaOS-CX switches.
質問 # 56
Switch-1 and Switch-2 are AruDaOS-CX switches, which ate part of a Virtual Switching Extension (VSX) fabric. Switch-2 is the primary member. Switch-2 experiences a power failure while Switch-l remains up. Switch-2's power recovers, and Switch-2 reboots.
Solution: Switch-2 wails a period called the link-up delay before it enables Switched Virtual Interfaces (SVls) on its VSX LAGs.
- A. No
- B. Yes
正解：B
質問 # 57
Refer to the exhibit.
You want to enable devices in VRF B and VRF C to reach shared resources in VRFA. is this a valid strategy for meeting this goal?
Solution: Create a separate OSPF process for each VRF on Switch-1. Then redistribute each process into the other VRFs' processes.
- A. No
- B. Yes
正解：A
解説：
Create a separate OSPF process for each VRF on Switch-1. Then redistribute each process into the other VRFs' processes is not a valid strategy for meeting this goal of enabling devices in VRF B and VRF C to reach shared resources in VRF A. This strategy would create unnecessary complexity and overhead on Switch-1, and it would not guarantee optimal routing between the VRFs. A better strategy would be to use inter-VRF routing or route leaking on Switch-1, which allows direct communication between different VRFs without requiring redistribution1.
質問 # 58
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: Create two configuration plans, one with the standard config and one with the device-specific settings.
- A. No
- B. Yes
正解：A
解説：
Creating two configuration plans, one with the standard config and one with the device-specific settings, is not what you should do. NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1. It also provides a plan feature that lets you create containers to group devices and execute operations on them, such as deploying, committing, or rolling back device configuration or firmware1. However, you do not need to create two configuration plans for your scenario. You can create one configuration plan with the standard config and use variables to define the device-specific settings1. Variables are placeholders that can be replaced with different values for different devices1. This way, you can deploy a standard config with device-specific settings using one configuration plan1.
質問 # 59
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: Different virtual MAC must be used for IPv4 and IPv6 Active Gateway.
- A. No
- B. Yes
正解：A
解説：
Different virtual MAC must be used for IPv4 and IPv6 Active Gateway is not a true statement about EVPN and IPv6 for configuring an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. Active Gateway is a feature that provides first-hop redundancy for hosts connected to VTEPs using anycast gateway addresses. Active Gateway can use the same virtual MAC address for both IPv4 and IPv6 protocols on the same VNI2.
質問 # 60
Is this part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) ring?
Solution: Combine multiple links between two data centers into link aggregations (but not multi-chassis ones).
- A. No
- B. Yes
正解：A
質問 # 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).
- A. No
- B. Yes
正解：B
質問 # 62
Two ArubaOS-CX switches ate part of a Virtual Switching Extension (V5X) fabric. Is this a guideline for configuring the switches' link-up delay settings?
Solution: Set the link-up delay timer based on the number of MAC forwarding, ARP, and routing table entries.
- A. No
- B. Yes
正解：B
解説：
Set the link-up delay timer based on the number of MAC forwarding, ARP, and routing table entries is a guideline for configuring the switches' link-up delay settings for Virtual Switching Extension (VSX) fabric. The link-up delay timer defines how long a VSX node waits before advertising link state changes to its peer node. This allows the node to synchronize its MAC forwarding, ARP, and routing tables with its peer node before sending or receiving traffic on the newly activated link1.
質問 # 63
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 VLAN10. except the incoming interface. It replicates the broadcast, encapsulates each broadcast with VXLAN. and sends the VXLAN traffic to 192.168.1.2 and 192.168.1.3.
- A. No
- B. Yes
正解：A
質問 # 64
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.
- A. No
- B. Yes
正解：A
解説：
ArubaOS-CX is a modern operating system for Aruba switches that provides automation, programmability, and analytics capabilities. The ArubaOS-CX Network Analytics Engine (NAE) is a built-in analytics framework for network assurance and remediation, that allows monitoring, troubleshooting, and proactive network management using scripts and agents1. The NAE does not help admins to manage multiple ArubaOS-CX switches together using familiar CLI commands. That is the function of the ArubaOS-CX Fabric Composer (AFC), which is a software-defined orchestration tool that simplifies data center fabric management. Therefore, this does not correctly describe the ArubaOS-CX architecture.
