• Question 111:

  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

  Correct Answer: A

  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.

• Question 112:

  Is this a difference between a typical data center network's requirements and a typical campus network's requirements?

  Solution: Data center networks are typically less oversubscribed than campus networks.

  A. Yes

  B. No

  Correct Answer: A

  Data center networks are typically less oversubscribed than campus networks is a difference between a typical data center network's requirements and a typical campus network's requirements. Oversubscription is the ratio of potential maximum demand to available capacity on a network link or device. Data center networks typically have higher bandwidth and lower latency requirements than campus networks, so they need to minimize oversubscription as much as possible1.

• Question 113:

  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

  Correct Answer: A

  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.

• Question 114:

  Your customer is using Nutanix AHV and they need a network orchestration tool to simplify network provisioning. Is this operation supported when Aruba Fabric Composer (AFC) is integrated with Nutanix?

  Solution: Automated provisioning of LAGs Between AHV and VSX

  A. Yes

  B. No

  Correct Answer: A

  Automated provisioning of LAGs between AHV and VSX is an operation supported when Aruba Fabric Composer (AFC) is integrated with Nutanix. AFC is a tool that provides automation and orchestration for managing data center networks composed of ArubaOS-CX switches. AFC can integrate with various data center software such as VMware vSphere, Nutanix AHV, Microsoft Hyper-V, etc. AFC can discover, monitor, and configure Nutanix AHV clusters and hosts using REST APIs. AFC can also automate the provisioning of LAGs between AHV and VSX by creating VSX LAGs or MC-LAGs on the ArubaOS-CX switches and configuring the corresponding LAGs on the AHV hosts1.

• Question 115:

  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. Yes

  B. No

  Correct Answer: B

  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.

• Question 116:

  Refer to the exhibit.

  

  : The company wants AtubaOS-CX switches to provide VXLAN services for several VMs and servers, as shown in the exhibit. Hypervisors will not run VXLAN for this solution. Is this part of a valid configuration to meet the requirements? Solution: Work with the server admins to assign a consistent VLAN for VMs 1 and 4. Assign interface 1/1/2 on Switch-1 to the same VLAN.

  A. Yes

  B. No

  Correct Answer: A

  Work with the server admins to assign a consistent VLAN for VMs 1 and 4. Assign interface 1/1/2 on Switch-1 to the same VLAN is part of a valid configuration to meet the requirements for providing VXLAN services for several VMs and servers using ArubaOS-CX switches. VMs 1 and 4 belong to the same VXLAN segment (VNI 5010), so they should be assigned to the same VLAN on their respective hypervisors. Interface 1/1/2 on Switch-1 should also be assigned to the same VLAN as VMs 1 and 4, so that Switch-1 can act as a VTEP for them1.

• Question 117:

  Refer to the exhibit.

  

  : The company wants AtubaOS-CX switches to provide VXLAN services for several VMs and servers, as shown in the exhibit. Hypervisors will not run VXLAN for this solution. Is this part of a valid configuration to meet the requirements? Solution: Attach VNIs 5010 and 5020 to interface 1/1/3 on Switch-2.

  A. Yes

  B. No

  Correct Answer: B

  Attach VNIs 5010 and 5020 to interface 1/1/3 on Switch-2 is not part of a valid configuration to meet the requirements for providing VXLAN services for several VMs and servers using ArubaOS-CX switches. VNIs are virtual network identifiers that are used to identify VXLAN segments. A VNI can only be attached to a VLAN interface, not a physical interface, on an ArubaOS-CX switch1.

• Question 118:

  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

  Correct Answer: A

  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.

• Question 119:

  You want to use NetEdit to configure an AtubaOS-CX switch.

  Is this a minimum requirement for setting up communications between the switch and NetEdit?

  Solution: Enable the REST interface in read-only mode.

  A. Yes

  B. No

  Correct Answer: B

  The solution is incorrect because enabling the REST interface in read-only mode is not a minimum requirement for setting up communications between the switch and NetEdit. NetEdit uses the REST interface to configure the switch, so it needs write access as well as read access. Therefore, enabling the REST interface in read-write mode is a minimum requirement for setting up communications between the switch and NetEdit.

• Question 120:

  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. Yes

  B. No

  Correct Answer: B

  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.
