NEW QUESTION # 28
Which statements are true about VSX LAG? (Select two.)

• A. The total number of configured links may not exceed 8 for the pair or 4 per switch
• B. Outgoing traffic is preferentially switched to local members of the LAG.
• C. Outgoing traffic is switched to a port based on a hashing algorithm which may be either switch in the pair
• D. LAG traffic is passed over VSX ISL links only while upgrading firmware on the switch pair
• E. Up to 255 VSX lags can be configured on all 83xx and 84xx model switches.

Answer: A,B

Explanation:
Explanation
The correct answers are A and D.
According to the web search results, VSX LAG 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. VSX LAGs span both aggregation switches and appear as one device to partner downstream or upstream devices or both when forming a LAG with the VSX pair2.
One of the statements that is true about VSX LAG is that the total number of configured links may not exceed
8 for the pair or 4 per switch1. This means that a VSX LAG across a downstream switch can have at most a total of eight member links, and a switch can have a maximum of four member links. When creating a VSX LAG, it is recommended to select an equal number of member links in each segment for load balancing1.
Another statement that is true about VSX LAG is that outgoing traffic is preferentially switched to local members of the LAG2. This means that when active forwarding and active gateway are enabled, north-south and south-north traffic bypasses the ISL link and uses the local ports on the switch. This optimizes the traffic path and reduces the load on the ISL link2.
The other statements are false or not relevant for VSX LAG. Outgoing traffic is not switched to a port based on a hashing algorithm, which may be either switch in the pair. This is a characteristic of MLAG (Multi-Chassis Link Aggregation), which is a different feature from VSX LAG. LAG traffic is not passed over VSX ISL links only while upgrading firmware on the switch pair. This is a scenario that may occur when performing hitless upgrades, which is a feature that allows software updates without impacting network availability. The number of VSX lags that can be configured on all 83xx and 84xx model switches is not 255, but depends on the switch model and firmware version. For example, the AOS-CX 10.04 supports up to 64 VSX lags for 8320 switches and up to 128 VSX lags for 8325 and 8400 switches.

NEW QUESTION # 29
How is Dynamic Multicast Optimization (DMO) implemented in an HPE Aruba wireless network?

• A. The controller converts multicast streams into unicast streams.
• B. DMO is configured globally for each SSID in use in the network.
• C. The AP uses OOS to provide equal air time for multicast traffic,
• D. DMO is configured individually tor each SSID in use in the network.

Answer: D

Explanation:
Explanation
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.

NEW QUESTION # 30
Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements After the configuration was complete, it was noted that a user assigned with the administrators role did not have the appropriate level of access on the switch.
The user was not limited to viewing nonsensitive configuration information and a level of 1 was not assigned to their role Which default management role should have been assigned for the user?

• A. sysadmin
• B. helpdesk
• C. config
• D. operators

Answer: D

Explanation:
Explanation
The default management role that should have been assigned for the user is B. operators.
The operators user role is a predefined role that allows users to view nonsensitive configuration information on the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The operators user role has a privilege level of 1, which is the lowest level of access on the switch1.
The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires1.

NEW QUESTION # 32
A network engineer recently identified that a wired device connected to a CX Switch is misbehaving on the network To address this issue, a new ClearPass policy has been put in place to prevent this device from connecting to the network again.
Which steps need to be implemented to allow ClearPass to perform a CoA and change the access for this wired device? (Select two.)

• A. Configure dynamic authorization on the switchport
• B. Use Dynamic Segmentation.
• C. Configure dynamic authorization on the switch.
• D. Bounce the switchport
• E. Confirm that NTP is configured on the switch and ClearPass

Answer: C,D

Explanation:
Explanation
CoA (Change of Authorization) is a feature that allows ClearPass to dynamically change the authorization and access privileges of a device after it has been authenticated1. CoA uses RADIUS messages to communicate with the network device and instruct it to perform an action, such as reauthenticating the device, applying a new VLAN or user role, or disconnecting the device2.
To enable CoA on a CX switch, the network engineer needs to configure dynamic authorization on the switch, which is a global command that allows the switch to accept RADIUS messages from ClearPass and execute the requested actions3. The network engineer also needs to specify the IP address and shared secret of ClearPass as a dynamic authorization client on the switch3.
To trigger CoA for a specific wired device, the network engineer needs to bounce the switchport, which is an action that temporarily disables and re-enables the port where the device is connected. This forces the device to reauthenticate and receive the new policy from ClearPass. Bouncing the switchport can be done manually by using the interface shutdown and no shutdown commands, or automatically by using ClearPass as a CoA server and sending a RADIUS message with the Port-Bounce-Host AVP (Attribute-Value Pair).

NEW QUESTION # 34
What is true regarding 802.11k?

• A. It reduces roaming delay by pre-authenticating clients with multiple target APs before a client roams to an AP
• B. It extends radio measurements to define mechanisms for wireless network management of stations
• C. It provides mechanisms for APs and clients to dynamically measure the available radio resources.
• D. It considers several metrics before it determines if a client should be steered to the 5GHz band, including client RSSI

Answer: C

Explanation:
802.11k is a standard that provides mechanisms for APs and clients to dynamically measure the available radio resources in a wireless network. 802.11k defines radio resource management (RRM) functions, such as neighbor reports, link measurement, beacon reports, etc., that allow APs and clients to exchange information about the RF environment and make better roaming decisions. The other options are incorrect because they describe other standards, such as 802.11r, 802.11v, or 802.11ax.

NEW QUESTION # 35
Your manufacturing client is deploying two hundred wireless IP cameras and fifty headless scanners in their warehouse. These new devices do not support 802.1X authentication.
How can HPE Aruba enhance security for these new IP cameras in this environment?

• A. MPSK provides for each device in the WLAN to have its own unique pre-shared Key.
• B. MPSK Local will allow the cameras to share a rey and the scanners to share a different
• C. Use MPSK Local to automatically provide unique pre-shared Keys for devices.
• D. Aruba ClearPass performs the 802.1X authentication and installs a certificate.

Answer: A

Explanation:
The best option to enhance security for the new IP cameras and scanners in this environment is C. MPSK provides for each device in the WLAN to have its own unique pre-shared key.
MPSK stands for Multi Pre-Shared Key, and it is a feature that allows different devices to connect to the same SSID with different pre-shared keys. This improves the security and scalability of the network, as each device can have its own key and role without requiring 802.1X authentication or an external policy engine. MPSK can be configured either locally on the AP or centrally on Aruba Central12.
The other options are incorrect because:
A) MPSK Local is a feature that allows the user to configure 24 PSKs per SSID locally on the device. These local PSKs would serve as an extension of the base MPSK functionality. However, MPSK Local is not suitable for this scenario, as it can only support up to 24 devices per SSID, while the client has 250 devices1.
B) Aruba ClearPass is a network access control solution that can perform 802.1X authentication and install certificates for devices. However, this option is not feasible for this scenario, as the new IP cameras and scanners do not support 802.1X authentication3.
D) MPSK Local will not allow the cameras to share a key and the scanners to share a different key. MPSK Local will assign a different key to each device, regardless of their type. Moreover, MPSK Local can only support up to 24 devices per SSID, while the client has 250 devices1.

Refer to the image.

Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7

• A. The AP is an outdoor access point.
• B. The AP is using a directional antenna.
• C. The AP is a remote access point.
• D. The AP is configured in Mesh mode

Answer: B

Explanation:
Explanation
The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna.
A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

NEW QUESTION # 38
Which component is used by the Aruba Network Analytics Engine (NAE)?

• A. Ruby-based scripts
• B. Lisp-based agents
• C. JSON-based scripts
• D. Current State Database

Answer: D

Explanation:
Explanation
The component that is used by the Aruba Network Analytics Engine (NAE) is D. Current State Database.
The Current State Database is a database that stores the configuration and state information of the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The NAE can access this database through the AOS-CX REST API and monitor the values of any data point using monitors. The NAE can also track the history of the values in a time-series database and correlate them with network events or configuration changes1. The Current State Database provides NAE with direct visibility into the entire current state of the device, which enables intelligent troubleshooting and automation of network tasks1.
The other options are incorrect because:
A: JSON-based scripts: JSON is a data format that is used to exchange information between applications. It is not a scripting language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language1.
B: Lisp-based agents: Lisp is a family of programming languages that are mainly used for artificial intelligence and functional programming. It is not a language that can be used by NAE. NAE agents are instances of scripts that run on the switch and collect relevant network information and trigger alerts or actions1.
C: Ruby-based scripts: Ruby is a general-purpose programming language that is known for its expressiveness and elegance. It is not a language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language1.

NEW QUESTION # 39
What are two advantages of splitting a larger OSPF area into a number of smaller areas? (Select two )

• A. It reduces processing overhead.
• B. It extends the LSDB
• C. It increases stability
• D. it simplifies the configuration.
• E. It reduces the total number of LSAs

Answer: A,C

Explanation:
Explanation
Splitting a larger OSPF area into a number of smaller areas has several advantages for network scalability and performance. Some of these advantages are:
* It increases stability by limiting the impact of topology changes within an area. When a link or router fails in an area, only routers within that area need to run the SPF algorithm and update their routing tables. Routers in other areas are not affected by the change and do not need to recalculate their routes.
* It reduces processing overhead by reducing the size and frequency of link-state advertisements (LSAs).
LSAs are packets that contain information about the network topology and are flooded within an area.
By dividing a network into smaller areas, each area has fewer LSAs to generate, store, and process,
* which saves CPU and memory resources on routers.
* It reduces bandwidth consumption by reducing the amount of routing information exchanged between areas. Routers that connect different areas, called area border routers (ABRs), summarize the routing information from one area into a single LSA and advertise it to another area. This reduces the number of LSAs that need to be transmitted across area boundaries and saves network bandwidth.

NEW QUESTION # 40
Refer to Exhibit:

A company has deployed 200 AP-635 access points. To take advantage of the 6 GHz band, the administrator has attempted to configure a new WPA3-OWE SSID in Central but is not working as expected.
What would be the correct action to fix the issue?

• A. Change the SSID to WPA3-Enterprise (CNSA).
• B. Change the SSID to WPA3-Enterprise (CCM).
• C. Change the SSID to WPA3-Personal.
• D. Change the SSID to WPA3-Enhanced Open.

Answer: D

Explanation:
Explanation
The correct action to fix the issue is C. Change the SSID to WPA3-Enhanced Open.
WPA3-OWE is not a valid SSID type in Central. OWE stands for Opportunistic Wireless Encryption, and it is a feature that provides encryption for open networks without requiring authentication. OWE is also known as Enhanced Open, and it is one of the options for WPA3 SSIDs in Central1.
According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure a WPA3 SSID is:
* Select the Security Level from the drop-down list. The following options are available:
* WPA3-Personal: This option uses Simultaneous Authentication of Equals (SAE) to provide stronger password-based authentication and key exchange than WPA2-Personal.
* WPA3-Enterprise: This option uses 192-bit cryptographic strength for authentication and encryption, as defined by the Commercial National Security Algorithm (CNSA) suite.
* WPA3-Enterprise (CCM): This option uses 128-bit cryptographic strength for authentication and
* encryption, as defined by the Counter with CBC-MAC (CCM) mode.
* WPA3-Enhanced Open: This option uses Opportunistic Wireless Encryption (OWE) to provide encryption for open networks without requiring authentication.
The other options are incorrect because:
* A. WPA3-Enterprise (CNSA) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.
* B. WPA3-Personal is a valid SSID type, but it requires a passphrase to join the network, which may not be suitable for the company's use case.
* D. WPA3-Enterprise (CCM) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.

NEW QUESTION # 42
When configuring UBT on a switch what will happen when a gateway role is not specified?

• A. The switch will put the client on the access VLAN
• B. The gateway will assign a default role to the client
• C. The switch will assign the default deny role to the client.
• D. The gateway will send back the deny role to the client.

Answer: A

Explanation:
According to the Aruba Documentation Portal1, user-based tunneling (UBT) is a feature that uses GRE to tunnel ingress traffic on a switch interface to a gateway for further processing. UBT enables a switch to provide a centralized security policy, using per-user authentication and access control to ensure consistent access and permissions.
Option A: The switch will put the client on the access VLAN
This is because option A shows how UBT works on an Aruba switch. When a device connects to the network, it is authenticated using either MAC Authentication or 802.1X and triggers an enforcement policy from ClearPass, which contains an enforcement profile with a user role configuration. The user role can be assigned locally on the switch or on ClearPass as part of an enforcement profile. The user role determines the VLAN that the device belongs to and the access policies that apply to it23.
Therefore, option A is correct.

Which statements are true about VSX LAG? (Select two.)

• A. Outgoing traffic is preferentially switched to local members of the LAG.
• B. The total number of configured links may not exceed 8 for the pair or 4 per switch
• C. LAG traffic is passed over VSX ISL links only while upgrading firmware on the switch pair
• D. Outgoing traffic is switched to a port based on a hashing algorithm which may be either switch in the pair
• E. Up to 255 VSX lags can be configured on all 83xx and 84xx model switches.

Answer: A,D

Explanation:
Explanation
VSX LAG is a feature that allows a pair of Aruba CX switches to form a multichassis LAG with a downstream or upstream device. VSX LAG provides link redundancy and load balancing across the two switches. Outgoing traffic from the VSX pair to the peer device is switched to a port based on a hashing algorithm that considers various parameters such as source and destination MAC addresses, IP addresses, ports, etc. The hashing algorithm may select a port that belongs to either switch in the pair, depending on the traffic characteristics1. However, outgoing traffic is preferentially switched to local members of the LAG, meaning that each switch tries to use its own ports first before using the ISL link to send traffic to the other switch's ports2. This reduces the ISL utilization and improves performance. References: 1

NEW QUESTION # 45
When setting up an Aruba CX VSX pair, which information does the Inter-Switch Link Protocol configuration use in the configuration created?

• A. MAC tables
• B. QSVI
• C. RPVST+
• D. UDLD

Answer: A

Explanation:
Explanation
The information that the Inter-Switch Link Protocol configuration uses in the configuration created is B. MAC tables.
The Inter-Switch Link Protocol (ISL) is a protocol that enables the synchronization of data and state information between two VSX peer switches. The ISL uses a version control mechanism and provides backward compatibility regarding VSX synchronization capabilities. The ISL can span long distances (transceiver dependent) and supports different speeds, such as 10G, 25G, 40G, or 100G1.
One of the data components that the ISL synchronizes is the MAC table, which is a database that stores the MAC addresses of the devices connected to the switch and the corresponding ports or VLANs. The ISL ensures that both VSX peers have the same MAC table entries and can forward traffic to the correct destination2. The ISL also synchronizes other data components, such as ARP table, LACP states for VSX LAGs, and MSTP states2.

AOS 10 Gateways can have the following personas: Mobility, Branch, and VPN Concentrator1 However, the Mobility persona is only available when configuring a Gateway-only group, which is a group that contains only one gateway device2 The Mobility persona provides Overlay WLAN and (or) wired LAN functionalities for campus networks1 The Branch persona provides the Aruba Instant OS and SD-Branch (LAN + WAN) functionality for branch and microbranch networks1 The VPN Concentrator persona provides VPN termination and routing functionality for remote access networks3 The Edge persona is not a valid option, as it is not a supported device persona for AOS 10 Gateways.

NEW QUESTION # 50
A new network design is being considered to minimize client latency in a high-density environment. The design needs to do this by eliminating contention overhead by dedicating subcarriers to clients.
Which technology is the best match for this use case?

• A. OFDMA
• B. MU-MIMO
• C. QWMM
• D. Channel Bonding

Answer: A

Explanation:
Explanation
OFDMA (Orthogonal Frequency Division Multiple Access) is a technology that can minimize client latency in a high-density environment by eliminating contention overhead by dedicating subcarriers to clients. OFDMA allows multiple clients to transmit simultaneously on different subcarriers within the same channel, reducing contention and increasing efficiency. MU-MIMO (Multi-User Multiple Input Multiple Output) is a technology that allows multiple clients to transmit simultaneously on different spatial streams within the same channel, but it does not eliminate contention overhead. QWMM (Quality of Service Wireless Multimedia) is a technology that prioritizes traffic based on four access categories, but it does not eliminate contention overhead. Channel Bonding is a technology that combines two adjacent channels into one wider channel, increasing bandwidth but not eliminating contention overhead. References:
