• Question 93:

  How is Dynamic Multicast Optimization (DMO) implemented in an HPE Aruba wireless network?

  A. DMO is configured individually tor each SSID in use in the network.

  B. The AP uses OOS to provide equal air time for multicast traffic,

  C. DMO is configured globally for each SSID in use in the network.

  D. The controller converts multicast streams into unicast streams.

  Correct Answer: A

  The correct answer is A. DMO is configured individually for each SSID in use in the network.

  DMO is a feature that allows the AP to convert multicast streams into unicast streams over the wireless link. This enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. DMO is

  configured individually for each SSID in use in the network, as different SSIDs may have different multicast requirements.

  According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure DMO is:

  Dynamic multicast optimization: Select Enabled to allow IAP to convert multicast streams into unicast streams over the wireless link. Enabling Dynamic Multicast Optimization (DMO) enhances the quality and reliability of streaming video,

  while preserving the bandwidth available to the non-video clients.

  The other options are incorrect because:

  B. The AP does not use QoS to provide equal air time for multicast traffic. QoS is a feature that prioritizes different types of traffic based on their importance and latency sensitivity. QoS does not affect how multicast streams are transmitted over the wireless link.

  C. DMO is not configured globally for each SSID in use in the network. DMO is configured individually for each SSID, as different SSIDs may have different multicast requirements.

  D. The controller does not convert multicast streams into unicast streams. The AP does the conversion, as it is closer to the wireless clients and can optimize the transmission based on the client capabilities and channel conditions.

• Question 94:

  Which statements regarding Aruba NAE agents are true? (Select two ) A. A single NAE script can be used by multiple NAE agents

  B. NAE agents are active at all times

  C. NAE agents will never consume more than 10% of switch processor resources

  D. NAE scripts must be reviewed and signed by Aruba before being used

  E. A single NAE agent can be used by multiple NAE scripts.

  Correct Answer: AC

  Explanation: The statements that are true regarding Aruba NAE agents are A and C. A. A single NAE script can be used by multiple NAE agents. This means that you can create different instances of the same script with different parameters or settings. For example, you can use the same script to monitor different VLANs or interfaces on the switch1.

  C. NAE agents will never consume more than 10% of switch processor resources. This is a built-in safeguard that prevents the agents from affecting the switch performance or stability. If an agent exceeds the 10% limit, it will be automatically

  disabled and an alert will be generated2.

  The other options are incorrect because:

  B. NAE agents are not active at all times. They can be enabled or disabled by the user, either manually or based on a schedule. They can also be disabled automatically if they encounter an error or exceed the resource limit1. D. NAE scripts

  do not need to be reviewed and signed by Aruba before being used. You can create your own custom scripts using Python and upload them to the switch or Aruba Central. You can also use the scripts provided by Aruba or other sources, as

  long as they are compatible with the switch firmware version1. E. A single NAE agent cannot be used by multiple NAE scripts. An agent is an instance of a script that runs on the switch. Each agent can only run one script at a time1.

• Question 96:

  A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.

  What statements are correct regarding the ERSPAN session that needs to be established on an AOS-CX switch'? (Select two )

  A. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected

  B. The encapsulation protocol used is GRE.

  C. The encapsulation protocol used is VXLAN.

  D. The encapsulation protocol is UDP.

  E. On the source AOS-CX switch, the destination specified is the administrators desktop

  Correct Answer: BE

  Explanation: These are the correct statements regarding the ERSPAN session that needs to be established on an AOS-CX switch for a network administrator to examine the packets over a period of time from their desktop. ERSPAN (Encapsulated Remote Switched Port Analyzer) is a feature that allows an AOS-CX switch to mirror traffic from one or more source ports or VLANs to a remote destination IP address over a GRE (Generic Routing Encapsulation) tunnel. The destination IP address must be the IP address of the administrator's desktop, which must have a packet capture tool installed to receive and analyze the mirrored traffic. The encapsulation protocol used for ERSPAN is GRE, which adds a header to the mirrored packets with information such as source and destination IP addresses, session ID, etc. The other statements are incorrect because they either do not specify the correct destination IP address or do not use ERSPAN or GRE.

  A company recently upgraded its campus switching infrastructure with Aruba 6300 CX switches. They have implemented 802.1X authentication on edge ports where laptop and loT devices typically connect An administrator has noticed that

  for PoE devices the pons are delivering the maximum wattage instead of what the device actually needs Upon connecting the loT devices, the devices request their specific required wattage through information exchange.

  Concerned about this waste of electricity, what should the administrator implement to solve this problem?

  A. Enable AAA authentication to exempt LLDP and/or CDP information

  B. Globally enable the QoS trust setting for LLDP and/or CDP

  C. Create device profiles with the correct power definitions.

  D. Implement a classifier policy with the correct power definitions.

  Correct Answer: D

  According to the Aruba Documentation Portal1, the Aruba 6300 CX switches support various features to control the PoE devices on specific ports, such as device profiles and classifier policies. These features can help reduce the power consumption and improve the performance of the PoE devices.

• Question 99:

  A customer is looking Tor a wireless authentication solution for all of their loT devices that meet the following requirements

  - The wireless traffic between the IoT devices and the Access Points must be encrypted

  -Unique passphrase per device

  -Use fingerprint information to perform role-based access

  Which solutions will address the customer's requirements? (Select two.)

  A. MPSK and an internal RADIUS server

  B. MPSK Local with MAC Authentication

  C. ClearPass Policy Manager

  D. MPSK Local with EAP-TLS

  E. Local User Derivation Rules

  Correct Answer: CD

  Explanation: The correct answers are C and D. MPSK (Multi Pre-Shared Key) is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless IoT devices1. MPSK requires MAC authentication against a ClearPass Policy Manager server, which returns the encrypted passphrase for the device in a RADIUS VSA2. ClearPass Policy Manager is a platform that provides role- and device-based network access control for any user across any wired, wireless and VPN infrastructure3. ClearPass Policy Manager can also use device profiling and posture assessment to assign roles based on device fingerprint information4. MPSK Local is a variant of MPSK that allows the user to configure up to 24 PSKs per SSID locally on the device, without requiring ClearPass Policy Manager5. MPSK Local can be combined with EAP-TLS (Extensible Authentication Protocol-Transport Layer Security), which is a secure authentication method that uses certificates to encrypt the wireless traffic between the IoT devices and the access points6. EAP-TLS can also use device certificates to perform role-based access control6. Therefore, both ClearPass Policy Manager and MPSK Local with EAP-TLS can meet the customer's requirements for wireless authentication, encryption, unique passphrase, and role-based access for their IoT devices. MPSK and an internal RADIUS server is not a valid solution, because MPSK does not support internal RADIUS servers and requires ClearPass Policy Manager789. MPSK Local with MAC Authentication is not a valid solution, because MAC Authentication does not encrypt the wireless traffic or use fingerprint information for role-based access2. Local User Derivation Rules are not a valid solution, because they do not provide unique passphrase per device or use fingerprint information for role-based access101112.

• Question 100:

  Your customer currently has Iwo (2) 5406 modular switches with MSTP configured as their core switches. You are proposing a new solution. What would you explain regarding the Aruba CX VSX switch pair when the Primary VSX node is replaced and the system MAC is replaced?

  A. VSX will select the MAC address from a node that is the lower ID.

  B. Configure vMAC on the Primary VSX node under VSX to retain MAC after hardware replacement.

  C. VSX will select the MAC address from a node that is a higher ID.

  D. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.

  Correct Answer: D

  The system-mac command is used to configure a fixed MAC address for the VSX system. This MAC address is used as the source MAC address for all routed traffic from the VSX node. The system-mac command is highly recommended for preventing traffic disruptions when the primary VSX switch restores after the secondary VSX switch, such as during a primary switch hardware replacement or a power outage2. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID. The system- mac command can be used to change this default MAC address if needed2. Therefore, answer D is correct. References: 1: Aruba Campus Access documents and learning resources 2: system-mac - Aruba
