NEW QUESTION # 18
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 Pending, which means that the ring is configured but not enabled administratively
- A. No
- B. Yes
Answer: A
Explanation:
The status is Pending, which means that the ring is configured but not operational. The ring instance may be in one of the following states: Idle, Initializing, Pending, or Failed1. The Pending state indicates that the ring instance is waiting for a trigger event to become operational, such as a link failure or a manual command1. The status does not depend on whether the ring is enabled administratively or not. https://www.arubanetworks.com/techdocs/AOS-CX/10.08/HTML/high_availability/Content/Chp_ERPS/ERPS_cmds/sho-erp-sta4.htm
NEW QUESTION # 19
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
Answer: A
Explanation:
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.
NEW QUESTION # 20
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. Yes
- B. No
Answer: A
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 # 21
A customer's servers use ISCSI, and they send data and storage traffic on the same pair of I OGbE links. Is this a best practice for supporting the ISCSI requirements?
Solution: Use Virtual Routing and Forwarding (VRF) to tunnel iSCSI traffic through the network spine on the same links that data traffic uses.
- A. No
- B. Yes
Answer: A
Explanation:
ISCSI is a protocol that allows storage devices to communicate over IP networks. ISCSI traffic has different requirements than data traffic, such as low latency, high throughput, and reliability. Therefore, it is not a best practice to send data and storage traffic on the same pair of 10GbE links, as this can cause congestion and performance degradation. It is also not a best practice to use Virtual Routing and Forwarding (VRF) to tunnel ISCSI traffic through the network spine on the same links that data traffic uses. VRF is a technology that creates multiple isolated Layer 3 domains on a physical network, each with its own routing table. VRF does not provide any benefits for ISCSI traffic, as it does not guarantee bandwidth, priority, or quality of service. VRF also adds overhead and complexity to the network configuration1. Therefore, this is not a valid way to support the ISCSI requirements.
NEW QUESTION # 22
Is this a guideline for establishing a Virtual Switching Extension (VSX) Inter-Switch Link (ISL) between two ArubaOS-CX switches?
Solution: Use the same speed on every link In the ISL.
- A. Yes
- B. No
Answer: A
Explanation:
The solution is correct because using the same speed on every link in the ISL is a guideline for establishing a VSX ISL between two ArubaOS-CX switches. Using the same speed on every link in the ISL ensures consistent performance and avoids potential issues with link aggregation. Therefore, using the same speed on every link in the ISL is a good practice for establishing a VSX ISL.

NEW QUESTION # 25
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: Asymmetric IRB requires a third L3 VNI to route packets between ingress and egress VTEPs.
- A. Yes
- B. No
Answer: A
Explanation:
Asymmetric IRB requires a third L3 VNI to route packets between ingress and egress VTEPs is 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. The Layer 3 VNI acts as a transit VNI for inter-VXLAN routing.
NEW QUESTION # 26
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
Answer: A
NEW QUESTION # 27
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 # 28
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. Yes
- B. No
Answer: A
Explanation:
The IPv6 and IPv4 overlay networks can be encapsulated with VXLAN and transmitted through the underlay network is a true statement about EVPN and IPv6 for configuring an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. VXLAN is a feature that provides Layer 2 extension over Layer 3 networks using UDP encapsulation. VXLAN can support both IPv4 and IPv6 overlay networks over an IPv4 or IPv6 underlay network2.
NEW QUESTION # 29
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. Yes
- B. No
Answer: A
Explanation:
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 is 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 MAC and IP addresses of hosts connected to VTEPs. Switch-1 receives a frame with destination MAC address, 00:50:56:15:16:28, which belongs to VM-2 on Switch-3. Switch-1 learns from EVPN that VM-2 is reachable through VTEP 192.168.1.2, which is Switch-3's loopback interface. Switch-1 encapsulates the frame with VXLAN and an IP header destined to 192.168.1.2 and sends it over the underlay network1.
NEW QUESTION # 30
Does this correctly describe Network Analytics Engine (NAE) limitations on ArubaOS-CX switches?

- A. Yes
- B. No
Answer: A
NEW QUESTION # 32
Is this correct positioning of AtubaOS-CX switches in the data center?
Solution: A data center will use a leaf-spine topology and requires 64 leaf switches. Aruba CX 8325 switches can be a good choice for both the leaf and spine switches.
- A. Yes
- B. No
Answer: A
Explanation:
ArubaOS-CX switches are designed for enterprise campus, aggregation, and data center networking use cases1. ArubaOS-CX switches support a leaf-spine topology, which is a two-layer network architecture that provides high performance, scalability, and reliability for data center networks2. Aruba CX 8325 switches are compact 1U switches that offer high density and high speed connectivity for both leaf and spine switches3. Aruba CX 8325 switches can support up to 32 ports of 100GbE or 48 ports of 25GbE and 8 ports of 100GbE3. For a data center that requires 64 leaf switches, Aruba CX 8325 switches can be a good choice for both the leaf and spine switches, as they can provide enough bandwidth and port density for the network traffic3. Therefore, this is a correct positioning of ArubaOS-CX switches in the data center, and the correct answer is yes. For more information on ArubaOS-CX switches and data center solutions, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet and the Aruba CX Switch Series datasheets3 .
NEW QUESTION # 33

Solution: Set up dedicated switches to connect to iSCSl arrays. Connect top of rack (ToR) switches, which will support both data and storage traffic, to those dedicated switches.
- A. Yes
- B. No
Answer: A
NEW QUESTION # 34
Is this part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) solution?
Solution: Create two ERPS instances for the ring and assign different VLANs and different ring protection links (RPL) to each instance.
- A. Yes
- B. No
Answer: A
Explanation:
Creating two ERPS instances for the ring and assigning different VLANs and different RPLs to each instance is part of a valid strategy for load sharing traffic across the links in an ERPS solution1. ERPS is a protocol that provides protection and recovery for Ethernet traffic in a ring topology1. It uses a RPL to block one of the links in the ring and prevent loops1. By creating two ERPS instances with different RPLs, you can use both links in the ring for different VLANs and achieve load sharing1.
NEW QUESTION # 35
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
Answer: A
Explanation:
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.
NEW QUESTION # 36
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
Answer: A
Explanation:
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.
NEW QUESTION # 37
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: omit the device-specific settings from the configuration plan and include them in command scripts instead.
- A. No
- B. Yes
Answer: A
NEW QUESTION # 38
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 # 39

Answer: A
NEW QUESTION # 40
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, light-click any device-specific parameters and modify the parameter per-device.
- A. No
- B. Yes
Answer: A
NEW QUESTION # 41
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
