NEW QUESTION # 81
Describe the difference between Class of Service (CoS) and Differentiated Services Code Point (DSCP).
Answer: C
Explanation:
CoS and DSCP are both methods of marking packets for quality of service (QoS) purposes. QoS is a mechanism that allows network devices to prioritize and differentiate traffic based on certain criteria, such as application type, source, destination, etc. CoS stands for Class of Service and is a 3-bit field in the 802.1Q VLAN tag header. CoS can only be used on Ethernet frames that have a VLAN tag, and it can only be preserved within a single VLAN domain. DSCP stands for Differentiated Services Code Point and is a 6-bit field in the IP header. DSCP can be used on any IP packet, regardless of the underlying layer 2 technology, and it can be preserved throughout the IP packet flow, unless it is modified by intermediate devices.

NEW QUESTION # 82
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 subcamers to clients.
Which technology is the best match for this use case?
Answer: C
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.

NEW QUESTION # 83
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2? (Select two.)
Answer: A,C
Explanation:
The correct steps that are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2 are A and D.
A) AP1 will cache the client's information and send it to the Key Management service. This is true because when a client associates and authenticates with AP1, AP1 will generate a pairwise master key (PMK) for the client and store it in its cache. AP1 will also send the PMK and other client information, such as MAC address, VLAN, and SSID, to the Key Management service, which is a centralized service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) devices1. The Key Management service will use this information to facilitate fast roaming for the client.
D) The Key Management service then generates R1 keys for AP2's neighbors. This is true because when the Key Management service receives the client information from AP1, it will use the PMK to derive R0 and R1 keys for the client. R0 keys are used to generate R1 keys, which are used to generate pairwise transient keys (PTKs) for encryption. The Key Management service will distribute the R1 keys to AP2 and its neighboring APs, which are determined by AirMatch based on RF proximity2. This way, when the client roams to AP2 or any of its neighbors, it can skip the 802.1X authentication and use the R1 key to quickly generate a PTK with the new AP3.
B) The Key Management service receives from AirMatch a list of all AP2's neighbors. This is false because the Key Management service does not receive this information from AirMatch directly. AirMatch is a feature that runs on MCs or MM devices and optimizes the RF performance of Aruba devices by using machine learning algorithms. AirMatch periodically sends neighbor reports to all APs, which contain information about their nearby APs based on signal strength and interference. The APs then send these reports to the Key Management service, which uses them to determine which APs should receive R1 keys for a given client2.
C) The Key Management service receives a list of all AP1 s neighbors from AirMatch. This is false for the same reason as B. The Key Management service does not receive this information from AirMatch directly, but from the APs that send their neighbor reports.
E) A client associates and authenticates with the AP2 after roaming from AP1. This is false because a client does not need to authenticate with AP2 after roaming from AP1 if it has already authenticated with AP1 and received R1 keys from the Key Management service. The client only needs to associate with AP2 and perform a four-way handshake using the R1 key to generate a PTK for encryption3. This is called fast roaming or 802.11r roaming, and it reduces the latency and disruption caused by full authentication.

NEW QUESTION # 84
Refer to the exhibit. A company with 1,471 employees 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 the HPE Aruba Networking Central but is not working as expected.
What would be the correct action to fix the issue?
Answer: D
Explanation:
On Aruba APs, WPA3-OWE is referenced as WPA3-Enhanced Open in the SSID security settings. To enable Opportunistic Wireless Encryption (OWE) for the 6 GHz band, configure the SSID as WPA3-Enhanced Open rather than just WPA3 or WPA3-Personal/Enterprise.
NEW QUESTION # 85
Your customer is having connectivity issues with a newly-deployed Microbranch group The access points in this group are online in Aruba Central, but no VPN tunnels are forming.
What is the most likely cause of this issue?
Answer: C
Explanation:
This is the most likely cause of the issue where the access points in a Microbranch group are online in Aruba Central, but no VPN tunnels are forming. A Microbranch group is a group that contains both APs and Gateways and allows them to form VPN tunnels for secure communication. The VPN tunnels use GRE (Generic Routing Encapsulation) as the encapsulation protocol and IPSec as the encryption protocol. If there is a firewall blocking GRE traffic between the AP and the gateway, the VPN tunnels cannot be established.
The other options are incorrect because they either do not affect the VPN tunnel formation or do not apply to a Microbranch group. References: https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help
