HP Aruba Certified Campus Access Professional Exam Sample Questions (Q61-Q66):

NEW QUESTION # 61
What is enabled by LLDP-MED? (Select two.)

Answer: A,E

Explanation:
These are two benefits enabled by LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery).
LLDP-MED is an extension of LLDP that provides additional capabilities for network devices such as VoIP phones and APs. One of the capabilities is to automatically configure voice VLANs for VoIP phones, which allows them to be placed in a separate VLAN from data devices and receive QoS and security policies.
Another capability is to request power as needed from PoE-enabled switch ports, which allows APs to adjust their power consumption and performance based on the available power budget. The other options are incorrect because they are either not enabled by LLDP-MED or not related to LLDP-MED. References:

NEW QUESTION # 62
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?

Answer: D

Explanation:
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 outage. 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 needed.


NEW QUESTION # 63
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)

Answer: C,E

Explanation:
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 # 64
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 # 65
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2? (Select two.)

Answer: B,D

Explanation:
Key Management is a service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) to optimize roaming performance for wireless clients. Key Management works with AirMatch, a service that optimizes radio resource management for Aruba APs, to pre-generate and distribute R1 keys for neighboring APs before a client roams.
When a wireless device is roaming from AP1 to AP2, the following steps are part of the Key Management workflow:
* The client associates and authenticates with AP1 using 802.1X or PSK methods.
* The Key Management service caches the client's information and generates an R0 key for the client.
* The Key Management service receives a list of all AP1's neighbors from AirMatch.
* The Key Management service then generates R1 keys for AP1's neighbors using the R0 key and sends them to the corresponding APs.
* When the client roams to AP2, one of AP1's neighbors, it performs an 802.11r fast transition using the pre-generated R1 key without needing to re-authenticate.
