This is because Best Effort traffic is all other kinds of non-detrimental traffic that are not sensitive to Quality of Service metrics (jitter, packet loss, latency). A typical example would be peer-to-peer and email applications2. Background traffic is a type of traffic that is used for system maintenance or backup purposes and does not affect the performance or availability of the network3.
Therefore, Best Effort traffic has a higher priority than Background traffic in terms of network resources allocation and management.

This is the correct statement about what happens when a client attempts to join the network and the WLAN is configured with OWE (Opportunistic Wireless Encryption). OWE is a standard that provides encryption for open networks without requiring any authentication or credentials from the client or the network. OWE uses a Diffie-Hellman key exchange mechanism to establish a secure session between the client and the AP without exchanging any authentication information. The other options are incorrect because they either describe scenarios that require authentication or encryption methods that are not used by OWE.

These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work.

VSX clustering is a feature that allows two Aruba CX switches to operate as a single logical device, providing high availability, scalability, and simplified management. VSX clustering has several benefits over spanning tree configuration, such as:
✑ Dual control plane provides better resiliency. Unlike stacking, where switches share a single control plane, VSX switches have independent control planes that synchronize their states over an inter-switch link (ISL). This means that if one switch fails or reboots, the other switch can continue to operate without affecting traffic flows or network services.
✑ Active-active forwarding provides better performance. Unlike spanning tree, where some links are blocked to prevent loops, VSX switches use all available links for forwarding traffic, providing load balancing and increased bandwidth utilization.
✑ Multichassis LAG provides better redundancy. Unlike single-chassis LAG, where all member ports belong to one switch, VSX switches can form multichassis LAGs with downstream or upstream devices, where member ports are distributed across both switches. This provides link redundancy and seamless failover in case of switch or port failure.

Wi-Fi calling is a feature that allows you to make or receive voice calls over Wi-Fi instead of cellular network. Wi-Fi calling can provide better voice quality and reliability in areas with poor or no cellular coverage.

This is the appropriate solution for this scenario where wireless 802.1X authentication will be against a RADIUS server in the cloud and the security team is concerned that the traffic between the AP and the RADIUS server will be exposed. RadSec, also known as RADIUS over TLS, is a protocol that provides encryption and authentication for RADIUS traffic over TCP and TLS. RadSec can be configured on both the AP and the RADIUS server to establish a secure tunnel for exchanging RADIUS packets. The other options are incorrect because they either do not provide encryption or authentication for RADIUS traffic or do not involve RadSec. References: https://www.securew2.com/blog/what-is-radsec/ https://www.cloudradius.com/radsec-vs- radius/

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.

To create a new OSPF configuration for a separate routing table, you need to create a new OSPF process ID with vrf name. This will create a new OSPF instance that is associated with the specified VRF and its routing table. The other options are incorrect because they either do not create a new OSPF instance or do not associate it with a VRF. References: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200- 6728/bk01-ch02.html https://www.arubanetworks.com/techdocs/AOS- CX/10.04/HTML/5200-6728/bk01-ch03.html

The correct answer is B. sysops.
The sysops user role is a predefined role that allows users to perform system operations on the switch, such as backup, restore, upgrade, or reboot. The sysops user role also has access to the PUT and POST methods for REST API, which can be used to modify the switch configuration. The sysops user role has a privilege level of 15, which is the highest level of access on the switch1.
The other options are incorrect because:
✑ A. sysadmin: The sysadmin user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The sysadmin user role does not have access to the REST API methods, and cannot perform firmware upgrades1.
✑ C. administrators: 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.
✑ D. config: The config user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The config user role does not have access to the REST API methods, and cannot perform firmware upgrades1.

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: https://www.arubanetworks.com/assets/ds/DS_AP510Series.pdf https://www.arubanetworks.com/assets/wp/WP_WiFi6.pdf

Encryption is a feature supported by SNMPv3 that provides an advantage over SNMPv2c. Encryption protects the confidentiality and integrity of SNMP messages by encrypting them with a secret key. SNMPv2c does not support encryption and relies on community strings for authentication and authorization, which are transmitted in clear text and can be easily intercepted or spoofed. Transport mapping, community strings, and GetBulk are features that are common to both SNMPv2c and SNMPv3. References: https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos- solutions/snmp/snmp.htm https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/snmp/snmpv3.htm

Loop protection is a feature that detects and prevents loops in layer 2 networks. Loop protection can be enabled on ports, LAGs, or VLANs. When loop protection is enabled, the switch sends periodic loop protection messages on the interface and expects to receive them back. If a loop protection message is received back on the same interface, it indicates a loop and the switch takes an action to disable the interface or block traffic on it3. The loop-protect re-enable-timer command is used to configure the length of time the switch waits before re-enabling an interface that was disabled due to loop detection. The default value is 0, which means that the interface remains disabled until manually re-enabled3. To automate the process of resuming the port operational state once a loop on a client port is cleared, the loop-protect re-enable-timer command can be used with a non-zero value on the interface range that includes the client ports3. Therefore, answer C is correct. References: 1: Aruba Campus Access documents and learning resources 3: Configuring loop protection - Aruba

MAC Caching is a feature that allows a guest user to bypass the captive portal page after the first authentication based on their MAC address1 MAC Caching can be enabled under the splash page settings in Aruba Cloud Guest2 MAC Caching can improve the user experience and reduce the network overhead by eliminating the need for repeated authentication.

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.

VXLAN is a technology that can be used to meet the requirement of using a legacy application that communicates at layer-2 across a layer-3 network. Static VXLAN is a feature that allows the creation of layer-2 overlay networks over a layer-3 underlay network using VXLAN tunnels. Static VXLAN does not require any control plane protocol or VTEP discovery mechanism, and can be configured manually on the Aruba CX 6200 switches. The other options are incorrect because they either do not support layer-2 communication over layer-3 network or are not supported by Aruba CX 6200 switches. References: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200- 6728/bk01-ch03.html https://www.arubanetworks.com/techdocs/AOS- CX/10.04/HTML/5200-6728/bk01-ch05.html

A session-based ACL is applied to traffic entering or leaving a port or VLAN based on the direction of the session initiation. To allow ping from any wired station to wireless clients but not vice versa, a session-based ACL should be used to deny icmp echo traffic from any source to any destination, and then permit icmp echo-reply traffic from any source to user destination. The user role represents wireless clients in AOS 10. References: https://techhub.hpe.com/eginfolib/Aruba/OS-CX_10.04/5200-6692/GUID- BD3E0A5F-FE4C-4B9B-BE1D-FE7D2B9F8C3A.html

The command loop-protect enables loop protection on each layer 2 interface (port, LAG, or VLAN) for which loop protection is needed. Loop protection can find loops in untagged layer 2 links, as well as on tagged VLANs.

PAPI is the protocol that is used to establish tunnels between the CX switch and the Aruba Gateway for Dynamic Segmentation1. By default, PAPI uses a simple checksum to verify the integrity of the messages, but it does not encrypt the payload2. This could expose the network to spoofing or replay attacks by malicious actors. To address this situation, the administrator must enable Enhanced PAPI security, which uses AES-256 encryption and HMAC-SHA1 authentication to protect the tunnel traffic2. Enhanced PAPI security can be enabled on the CX switch by using the command system papi enhanced- security enable3. This will ensure that the tunnels built between the CX switch and the Aruba Gateway are encrypted and authenticated.

Wi-Fi 6 is an industry certification for products that support the new wireless standard 802.11ax, also known as ??high-efficiency wireless??. Wi-Fi 6 offers increased capacities, improved resource utilization and higher throughput speeds than previous standards.
Option B: ClientMatch
This is because option B shows how to use ClientMatch to optimize the wireless performance of Wi-Fi 6 clients on a UniFi network. ClientMatch is a feature that uses machine learning to analyze the traffic patterns of each client and assign them to the best available AP based on their location, device type, and network conditions2.
Therefore, option B is the best technology to implement for your customer??s issue.

The Aruba CX 6400 switch is a modular switch that supports high- performance and high-density Ethernet switching for campus and data center networks. One of the features that distinguishes the Aruba CX 6400 switch from most typical campus switches is virtual output queueing (VOQ). VOQ is a technique that implements large ingress packet buffers on each port to prevent head-of-line blocking and packet loss due to congestion2. VOQ allows each port to have multiple queues for different output ports and prioritize packets based on their destination and QoS class2. VOQ enables the Aruba CX 6400 switch to achieve high throughput and low latency for various traffic types and
scenarios. References: 2 https://www.arubanetworks.com/assets/ds/DS_CX6400Series.pdf

These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios that are not possible or not relevant to the question. References: https://www.arubanetworks.com/techdocs/AOS- CX/10.04/HTML/5200-6728/bk01-

Option A: MTU size must be increased beyond the default
This is because option A shows how to configure the MTU size for VXLAN tunnels on Aruba switches using the interface command and the vxlan command. The MTU size must be increased beyond the default value of 1500 bytes to accommodate the VXLAN header and payload2.
Therefore, option A is true regarding a VXLAN implementation on Aruba switches. Option B: VNIs encapsulate and decapsulate VXLAN traffic
This is also true regarding a VXLAN implementation on Aruba switches. VNIs are used to encapsulate and decapsulate VXLAN traffic between two devices, such as a switch and a server. VNIs are also used to map VXLAN tunnels to overlay networks3.
Therefore, option B is also true regarding a VXLAN implementation on Aruba switches. VXLAN is a Layer 2 encapsulation technology that substitutes the usage of VLAN numbers to label Ethernet broadcast domains with VXLAN numbers. VXLAN supports 224 Ethernet broadcast domains or VXLAN numbers. A VXLAN number ID is referred to as VNI. There is a one-to-one relationship between an Ethernet broadcast domain and a VNI. A single Ethernet broadcast domain can??t have more than one VNI.

The reason is that the Inter-Switch Link Protocol (ISLP) is a protocol that enables VSX stack join and synchronization between two VSX peer switches. ISLP uses a hello interval to exchange control messages between the switches.
The hello interval is a parameter that specifies the time interval between sending hello messages. The default value of the hello interval is 1 second. The hello interval can be configured from 1 second to 10 seconds. https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/index.html

Spectrum Monitor is an Aruba AP mode that is sending captured RF data to Aruba Central for waterfall plot. Spectrum Monitor is a mode that allows an AP to scan all channels in both 2.4 GHz and 5 GHz bands and collect information about the RF environment, such as interference sources, noise floor, channel utilization, etc. The AP then sends this data to Aruba Central, which is a cloud-based network management platform that can display the data in various formats, including waterfall plot. Waterfall plot is a graphical representation of the RF spectrum over time, showing the frequency, amplitude, and duration of RF signals. The other options are incorrect because they are either not AP modes or not sending RF data to Aruba Central.

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.

802.11mc is a standard that uses Round Trip Time (RTT) and Fine Time Measurements (FTM) to calculate the distance a client is from an AP. 802.11mc defines a protocol for exchanging FTM frames between an AP and a client, which contain timestamps that indicate when the frames were transmitted and received. By measuring the RTT of these frames, the AP or the client can estimate their distance based on the speed of light. The other options are incorrect because they either do not use RTT or FTM or do not exist as standards.

To establish a keepalive connection between two Aruba CX 8325 switches for VSX configuration, you need to use a routed port in custom VRF. A routed port is a physical port that acts as a layer 3 interface and does not belong to any VLAN. A custom VRF is a virtual routing and forwarding instance that provides logical separation of routing tables. By using a routed port in custom VRF, you can isolate the keepalive traffic from other traffic and prevent routing loops or conflicts. The other options are incorrect because they either do not use a routed port or do not use a custom VRF.

The Equivalent Isotropic Radiated Power (EIRP) is the measured radiated power of an antenna in a specific direction. It is also called Equivalent Isotropic Radiated Power. It is the output power when a signal is concentrated into a smaller area by the Antenna. The EIRP can take into account the losses in transmission line, connectors and includes the gain of the antenna. It is represented in dB2. The formula for EIRP is:
EIRP=PTLc+Ga where PT is the output power of the transmitter in dBm, Lc is the cable and connector loss in dB, and Ga is the antenna gain in dBi.
For AP1, the EIRP can be calculated as: EIRP=164+8=20 dBm
Therefore, the answer B is correct.
