Question 1

Is this correct positioning of AtubaOS-CX switches in the data center?

Solution: Aruba CX 6300 switches are an appropriate choice for leaf switches in a leaf-spine topology that uses Virtual Extensible LAN (VXLAN) with Ethernet VPN (EVPN).

AYes

BNo

Correct answer: A

Aruba CX 6300 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 6300 switches are designed for data center leaf roles, and they support advanced features such as VSX, EVPN, and PFC that enable high performance, scalability, and resiliency for data center networks1

Question 2

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.

AYes

BNo

Correct answer: A

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.

Question 3

Refer to the exhibits.

Is this how the switch handles the traffic?

Solution: A frame with destination MAC address, 00:50:56:00:00:03 arrives with a VLAN 10 tag on 1/1//1 on Switch-1. Switch-1 switches the frame out interface 1/1/2 without VXLAN.

AYes

BNo

Correct answer: B

VXLAN is a tunneling protocol that encapsulates layer 2 traffic over an IP network using VXLAN Network Identifiers (VNIs) to identify different layer 2 segments. VXLAN Tunnel Endpoints (VTEPs) are devices that perform the encapsulation and decapsulation of VXLAN packets. According to the exhibit, Switch-1 and Switch-2 are VTEPs that use VNI 10010 to map VLAN 10 traffic.Therefore, when Switch-1 receives a frame with destination MAC address 00:50:56:00:00:03 and VLAN 10 tag on interface 1/1/1, it should encapsulate the frame with a VXLAN header that contains VNI 10010 and send it as a unicast packet to Switch-2's loopback address (10.1.1.2) over the IP network1. Switch-1 should not switch the frame out interface 1/1/2 without VXLAN, as this would violate the VNI mapping and cause layer 2 loops. Therefore, this is not how the switch handles the traffic. https://networklessons.com/cisco/ccnp-encor-350-401/introduction-to-virtual-extensible-lan-vxlan

Question 4

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.

AYes

BNo

Correct answer: A

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.

Question 5

Does this correctly describe how Network Analytics Engine (NAE) agents work?

Solution: Agents collect data every minute and send the data to a centralized SNMP server in SNMP traps.

AYes

BNo

Correct answer: B

Agents do not collect data every minute and send the data to a centralized SNMP server in SNMP traps.NAE is a feature that provides network operators with distributed analytics for faster troubleshooting and resolution of network-impacting issues1.Agents are scripts that run on ArubaOS-CX switches and collect data from various sources, such as CLI commands, REST APIs, or syslog messages1.Agents can also define conditions and actions based on the collected data1.Agents do not send the data to a centralized SNMP server, but store it locally on the switch1.Agents can also send alerts to external systems, such as email servers or syslog servers, but not in SNMP traps1. The statement is false because it incorrectly describes how NAE agents work.
