- B. Yes
Answer: A
NEW QUESTION # 23
Is this a difference between a typical data center network's requirements and a typical campus network's requirements?
Solution: Data center network traffic flows are typically east-west whereas while campus networks experience more north-south traffic.
- A. No
- B. Yes
Answer: B
Explanation:
A data center network is a network that connects servers, storage devices, and other devices within a data center. A campus network is a network that connects buildings and users within a campus area, such as a university or an enterprise. Data center network traffic flows are typically east-west, which means they are between servers or devices within the data center. This is because data center applications often require high-speed communication and data exchange between servers for processing, analysis, or backup. Campus network traffic flows are typically north-south, which means they are between users or devices and external networks, such as the Internet or a wide area network (WAN). This is because campus users often access online services or resources that are hosted outside the campus network12. Therefore, this is a valid difference between a typical data center network's requirements and a typical campus network's requirements.
NEW QUESTION # 24
Is this a use case for disabling split-recovery mode on ArubaOS-CX switches in a Virtual Switching Extension (VSX) fabric?
Solution: You are not concerned about split Drain Issues in your environment, so you want the secondary member to keep its links up if the ISL falls.
- A. No
- B. Yes
Answer: B

NEW QUESTION # 26
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 Application Priority Map Local advertisement section
- A. No
- B. Yes
Answer: B
Explanation:
The show dcbx interface command shows the current DCBx status and the configuration of PFC, ETS, and application priority applied on the interface and the status of the TLVs received from the peer1. The Application Priority Map section shows the protocol, port/type and priority for both local and remote advertisements. Therefore, this is where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX.

NEW QUESTION # 27
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. No
- B. Yes
Answer: B
Explanation:
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.

Solution: In situations in which the primary switch fails and then reboots, you want to make the primary switch take over again as the primary switch.
- A. No
- B. Yes
Answer: A
NEW QUESTION # 30
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
- A. No
- B. Yes
Answer: A
NEW QUESTION # 31
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.
- A. No
- B. Yes
Answer: A
Explanation:
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 # 32
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
Answer: B
Explanation:
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.
NEW QUESTION # 33
Refer to the exhibit.
Switch-1 and Switch-2 ate ArubaOS-CX switches that implement VXLAN WITHOUT Ethernet VPN (EVPN). Switch-2 uses the same VNI-to-VLAN mappings as Switch-1. Is this how the specified servers communicate?
Solution: The first time that Server I communicates with Server 3, It sends an ARP request to resolve Server 3's MAC address.
- A. No
- B. Yes
Answer: A
Explanation:
The solution is incorrect because Switch-1 and Switch-2 implement VXLAN without EVPN, which means they do not have a control plane to exchange MAC addresses. Therefore, the first time that Server 1 communicates with Server 3, it sends an ARP request to resolve Server 3's IP address, not MAC address. The ARP request is encapsulated in a VXLAN header and sent to the VTEP of Switch-2, which decapsulates it and forwards it to Server 3.
NEW QUESTION # 34
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
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. 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 # 35
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 # 36
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
- A. No
- B. Yes
Answer: B
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 # 37
Does this correctly describe NetEdit's notification capabilities?
Solution: NetEdit notifies admins of errors using Its Internal email server.
- A. No
- B. Yes
Answer: A
NEW QUESTION # 38
Does this correctly describe routing information advertised by a VXLAN Tunnel Endpoint (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: B
Explanation:
MAC/IP advertisement routes advertise the MAC addresses that can be reached through the VTEP is a correct description of routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN. EVPN is a feature that provides control plane learning and signaling for VXLAN networks. MAC/IP advertisement routes are one of the types of routes that EVPN uses to advertise MAC and IP addresses of hosts connected to VTEPs2.
NEW QUESTION # 39
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
Answer: A
Explanation:
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.
NEW QUESTION # 40
Does this correctly describe how the Virtual Switching Extension (VSX) fabric reacts to various component failure scenarios?
Solution: The keepalive goes down, ISL link remains up. Switch-1 and Switch-2 remains up. The Split-recovery mode is disabled. In this case the secondary switch shutdowns Svls.
- A. No
- B. Yes
Answer: A
Explanation:
The keepalive goes down, ISL link remains up. Switch-1 and Switch-2 remains up. The Split-recovery mode is disabled. In this case the secondary switch shutdowns SVIs is not a correct description of how the Virtual Switching Extension (VSX) fabric reacts to various component failure scenarios. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. The ISL is the inter-switch link that connects two VSX nodes and carries data traffic. The keepalive link is a separate link that carries control traffic between two VSX nodes. The split-recovery mode is a feature that prevents split-brain scenarios when both VSX nodes lose connectivity with each other but remain up. When the keepalive goes down, but the ISL link remains up, both VSX nodes continue to forward traffic normally and do not shut down their SVIs because they can still exchange synchronization messages over the ISL link1.
NEW QUESTION # 41
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
Answer: A
NEW QUESTION # 42
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 broadcasts as unicast packets to each VTEP in the same VNI.
- A. No
- B. Yes
Answer: B
Explanation:
Headend replication is a method of handling BUM traffic in VXLAN networks without EVPN, where the ingress VTEP replicates every BUM packet and sends them as a separate unicast to the remote egress VTEPs in the same VNI1. This avoids the need for multicast routing in the underlay network, but it can increase the load on the ingress VTEP. Therefore, this correctly describes how the VTEPs handle VXLAN traffic forwarding without EVPN.
