• Question 51:

  Is this how you should position switches in the ArubaOS-CX portfolio for data center networks?

  Solution: Deploy Aruba 8400 switches as data center leaf switches.

  A. Yes

  B. No

  Correct Answer: B

  The ArubaOS-CX portfolio for data center networks consists of different switches for different roles. The Aruba 8400 switches are designed for the core and aggregation layers, while the Aruba CX 6300 and CX 6400 switches are designed for the leaf layer1. Therefore, deploying Aruba 8400 switches as data center leaf switches is not how you should position switches in the ArubaOS-CX portfolio for data center networks.

• Question 52:

  Does this correctly describe NetEdit's notification capabilities?

  Solution: NetEdit notifies admins of errors using Its Internal email server.

  A. Yes

  B. No

  Correct Answer: B

  NetEdit is a network management tool that allows you to configure, monitor, and troubleshoot ArubaOS-CX switches. NetEdit can send notifications of changes in network conditions to other services, such as email, using methods that define the service type and credentials. However, NetEdit does not use its internal email server to send notifications. NetEdit requires an external SMTP server to send email notifications, and the SMTP server address, port, username, and password must be configured in the email method1. Therefore, this does not correctly describe NetEdit's notification capabilities.

• Question 53:

  Does this correctly describe Network Analytics Engine (NAE) limitations on ArubaOS-CX switches?

  Solution: Different switches have different limitations for the number of NAE scripts, monitors, and agents supported.

  A. Yes

  B. No

  Correct Answer: A

  Different switches have different limitations for the number of NAE scripts, monitors, and agents supported is a correct description of Network Analytics Engine (NAE) limitations on ArubaOS-CX switches. NAE is a feature that provides automation and analytics for managing ArubaOS-CX switches. NAE scripts are scripts that run on switches and collect data from various sources. NAE monitors are rules that define conditions and actions for NAE agents. NAE agents are instances of NAE scripts and monitors that run on switches. Different switches have different limitations for the number of NAE scripts, monitors, and agents supported depending on their hardware resources1.

• Question 54:

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

  Solution: Agents write data to the switch's current state database.

  A. Yes

  B. No

  Correct Answer: A

  Agents write data to the switch's current state database is a correct description of how Network Analytics Engine (NAE) agents work. NAE agents are scripts that run on ArubaOS-CX switches and collect data from various sources such as CLI commands, REST APIs, SNMP queries, etc. The agents write the collected data to the switch's current state database (CSDB), which stores information about the switch's configuration, status, and performance1.

• Question 55:

  Does this correctly describe NetEdit's notification capabilities?

  Solution: NetEdlt can send an error link to admins through ServlceNow.

  A. Yes

  B. No

  Correct Answer: A

  NetEdit is a network management tool that allows you to configure, monitor, and troubleshoot ArubaOS-CX switches. NetEdit can send notifications of changes in network conditions to other services, such as ServiceNow, using methods that define the service type and credentials. ServiceNow is a cloud-based platform that provides IT service management and digital workflows. NetEdit can send an error link to admins through ServiceNow, which allows them to view the details of the error and take actions to resolve it

  1. Therefore, this correctly describes NetEdit's notification capabilities.

• Question 56:

  Is this a use case for deploying Ethernet Ring Protection Switching (ERPS)?

  Solution: connecting multiple data centers at Layer 2 while minimizing the number of dark fiber connections required

  A. Yes

  B. No

  Correct Answer: A

  Connecting multiple data centers at Layer 2 while minimizing the number of dark fiber connections required is a use case for deploying Ethernet Ring Protection Switching (ERPS). ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. ERPS can be used to connect multiple data centers at Layer 2 using fewer fiber connections than traditional mesh topologies1.

• Question 57:

  Is this a guideline for establishing a Virtual Switching Extension (VSX) Inter-Switch Link (ISL) between two ArubaOS-CX switches?

  Solution: Use a link aggregation with multiple 40GbE links or multiple 100GbE links.

  A. Yes

  B. No

  Correct Answer: A

  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 recommended that the ISL link is a link aggregation with multiple 40GbE links or multiple 100GbE links to provide redundancy and bandwidth1. Therefore, this is a valid guideline for establishing a VSX ISL between two ArubaOS-CX switches.

• Question 58:

  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 take over again as the primary switch.

  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. Split-recovery mode is a feature that prevents traffic loss when the Inter-Switch Link (ISL) goes outof-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 takes over again as the primary switch after a failure and reboot. The primary switch always takes over as the primary switch when it comes back online, regardless of the split-recovery mode setting. Therefore, this is not a use case for disabling split-recovery mode on ArubaOS-CX switches in a VSX fabric.

• Question 59:

  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. Yes

  B. No

  Correct Answer: A

  You cannot leak multicast routes is a rule for the setup of multi-protocol BGP to implement dynamic VRF route leaking on an ArubaOS-CX switch. Multi-protocol BGP only supports unicast routes for route leaking, and multicast routes are not leaked between VRFs1.

• Question 60:

  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.

  A. Yes

  B. No

  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- virtualextensible-lan-vxlan
