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.

Suggested answer: A

Explanation:

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.

Explanation:

Aruba CX 8325 switches are an appropriate choice for leaf switches in a leaf-spine topology that uses Virtual Extensible LAN (VXLAN) with Ethernet VPN (EVPN) is a correct positioning of ArubaOS-CX switches in the data center. The Aruba CX 8325 switches are designed for data center spine or core roles, but they can also be used as leaf switches in a VXLAN with EVPN scenario. They support advanced features such as VSX, EVPN, and PFC that enable high performance, scalability, and resiliency for data center networks1.

The control VLANs must be unique for each ring instance and must not overlap with any protected VLANs. In this design, the control VLAN 1000 is used for both ring 1 instance 1 and ring 2 instance 1, which can cause conflicts and errors. Also, the protected VLANs 181-220 are used for both ring instances on ring 2, which can cause loops and traffic duplication2.

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 Protection, which means that the ring is up and fully connected with the RPL port blocked.

Answers
Suggested answer: A

Explanation:

The status is Protection, which means that the ring is up and fully connected with the RPL port blocked is what the specified status means for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Protection is one of the possible statuses for an ERPS ring instance, and it indicates that the ring is operating normally with one port blocked to prevent loops. The RPL port is the port that connects to the RPL node, which is responsible for blocking and unblocking traffic on the ring2

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.

Suggested answer: B

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.

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.

Explanation:

In the Asymmetric IRB egress VTEPs bridge the traffic to the destination networks is not 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.

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.

Answers
Suggested 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.
