NEW QUESTION # 72
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.
- A. No
- B. Yes
Answer: A
Explanation:
The aggregation layer operates at Layer 2 only, and the core provides Layer 2 and Layer 3 functions is not a use case for implementing Virtual Switching Extension (VSX) at the core for a data center that has a three-tier topology with ArubaOS-CX switches at each layer. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSX can be implemented at any layer of the data center network, but it is more common to implement it at the aggregation or leaf layer, where it can provide Layer 2 and Layer 3 functions. The core layer typically operates at Layer 3 only and does not require VSX2.
NEW QUESTION # 73
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.
- A. No
- B. Yes
Answer: A
Explanation:
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 network1. It uses VXLAN tunnels to encapsulate Ethernet frames in UDP packets and transport them across the underlay network1. The underlay network can use either IPv4 or IPv6 protocol, but it must match the protocol used by the VXLAN tunnels1. The statement is false because it implies that IPv6 protocol can be encapsulated in IPv4 packets, which is not possible.
NEW QUESTION # 74
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
Answer: A
Explanation:
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.
NEW QUESTION # 75
Does this correctly describe routing information advertised by a VXLAN Tunnel Endpomt (VTEP) that uses EVPN?
Solution: MAC/IP advertisement routes advertise the MAC addresses that can be reached through the VTEP.
- A. No
- B. Yes
Answer: A
NEW QUESTION # 76
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?

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
- A. Yes
- B. No
Answer: A
Explanation:
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 VLANs2.
NEW QUESTION # 78
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
- A. Yes
- B. No
Answer: A
Explanation:
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.
NEW QUESTION # 79
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: The IPv6 and IPv4 overlay networks can be encapsulated with VXLAN and transmitted through the underlay network.
- A. No
- B. Yes
Answer: A
NEW QUESTION # 80
Can you attach this type of ArubaOS-CX interface to a VRF?
Solution: a layer 2 VLAN
- A. No
- B. Yes
Answer: A
Explanation:
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.
NEW QUESTION # 81
Is this a use case for disabling split-recovery mode on ArubaOS-CX switches in a Virtual Switching Extension (VSX) fabric?
Solution: In situations in which the primary switch fails and then reboots, you want to make the primary switch wait a period before it takes over as the primary switch.
- A. No
- B. Yes
Answer: A
Explanation:
Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. Split-recovery mode is a feature that prevents traffic loss when the Inter-Switch Link (ISL) goes out-of-sync and keepalive subsequently fails. When split-recovery mode is enabled, the secondary VSX member disables its downstream links until it synchronizes with the primary member. When split-recovery mode is disabled, the secondary VSX member keeps its downstream links up even when it is out-of-sync with the primary member1. Disabling split-recovery mode does not affect how the primary switch waits a period before it takes over as the primary switch after a failure and reboot. The primary switch always takes over as the primary switch immediately when it comes back online, regardless of the split-recovery mode setting. To make the primary switch wait a period before it takes over as the primary switch, you need to configure a preemption delay on both VSX members1. Therefore, this is not a use case for disabling split-recovery mode on ArubaOS-CX switches in a VSX fabric.
NEW QUESTION # 82
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
Answer: A
Explanation:
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)1.

NEW QUESTION # 84
Is this a requirement for implementing Priority Flow Control (PFC) on an ArubaOS-CX switch interface?
Solution: configuring trust of Cos on the interface
- A. Yes
- B. No
Answer: A
Explanation:
Configuring trust of CoS on the interface is a requirement for implementing Priority Flow Control (PFC) on an ArubaOS-CX switch interface. PFC is a feature that allows a switch to pause traffic on a per-class basis using IEEE 802.1Qbb frames. To use PFC, the switch must trust the CoS values in the incoming frames and map them to priority groups and queues1.
NEW QUESTION # 85
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 customer wants to deploy a single control plane for the core fabric.
- A. No
- B. Yes
Answer: A
Explanation:
The Virtual Switching Extension (VSX) is a high availability solution that provides industry-leading performance and simplicity for campus and data center networks1. VSX does not implement a single control plane for the core fabric, but rather a dual control plane that allows independent software upgrades and configuration changes on each switch2. VSX also provides active-active forwarding and load balancing across both switches, eliminating the need for Spanning Tree Protocol (STP) or other loop prevention mechanisms2. Therefore, this is not a use case for implementing VSX at the core. Reference: https://www.arubanetworks.com/assets/tg/TB_VSX.pdf
NEW QUESTION # 86
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
Answer: A
NEW QUESTION # 87
Is this a use case for deploying Ethernet Ring Protection Switching (ERPS)?
Solution: extending Layer 2 communications between data centers that connect over Layer 3 MPLS links
- A. No
- B. Yes
Answer: A
Explanation:
Extending Layer 2 communications between data centers that connect over Layer 3 MPLS links is not a use case for deploying Ethernet Ring Protection Switching (ERPS). ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. ERPS does not support extending Layer 2 communications over Layer 3 networks such as MPLS1.
NEW QUESTION # 88
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. Yes
- B. No
Answer: A
NEW QUESTION # 89
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. Yes
- B. No
Answer: A
Explanation:
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.
NEW QUESTION # 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 force the router to use both links, ensure that active gateway is enabled on LAG 100 on both Switch-1 and Switch-2.
- A. No
- B. Yes
Answer: A
Explanation:
The exhibit shows a network topology where Switch-1 and Switch-2 are part of a Virtual Switching Extension (VSX) fabric, and the router runs OSPF on LAG 100, which is a Layer 3 LAG. The question asks how to control how core-to-access traffic is forwarded, which means how the router chooses between the two links to Switch-1 and Switch-2. To force the router to use both links, ensuring that active gateway is enabled on LAG 100 on both Switch-1 and Switch-2 is not the correct solution. Active gateway is a feature that allows both VSX members to act as the default gateway for downstream devices, using a common virtual MAC address. Active gateway does not affect how upstream devices, such as the router, forward traffic to the VSX members1. To force the router to use both links, the correct solution is to configure equal-cost multi-path (ECMP) in OSPF on the router. ECMP is a feature that allows a router to load balance traffic across multiple paths with the same cost. ECMP can be configured using the maximum-paths command and specifying how many equal-cost paths the router should use2. Therefore, this does not correctly explain how to control how core-to-access traffic is forwarded.
NEW QUESTION # 91
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. Yes
- B. No
Answer: A
Explanation:
Combine multiple links between two data centers into link aggregations (but not multi-chassis ones) is 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. ERPS can support link aggregation groups (LAGs) between two nodes in a ring as long as they are not multi-chassis LAGs (MC-LAGs). MC-LAGs are not supported by ERPS because they can create loops in the ring topology.
NEW QUESTION # 92
