Dependable HPE7-A01 Exam Dumps to Become HP Certified

Q26. You are troubleshooting an issue with a pair of Aruba CX 8360 switches configured with VSX Each switch has multiple VRFs. You need to find the IP address of a particular client device with a known MAC address You run the “show arp” command on the primary switch in the pair but do not find a matching entry for the client MAC address.
The client device is connected to an Aruba CX 6100 switch by VSX LAG.
Which action can be used to find the IP address successfully?

Q27. List the WPA 4-Way Handshake functions in the correct order.

Q28. Refer to Exhibit:

With Access-1, What needs to be identically configured With MSTP to load-balance VLANS?

Spanning-tree bpdu-guard setting

Spanning-tree instance vlan mapppjng

spanning-tree Cist mapping

Spanning-tree root-guard setting

Explanation
The correct answer is B. Spanning-tree instance VLAN mapping.
To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.
According to the Cisco document Understand the Multiple Spanning Tree Protocol (802.1s), one of the steps to configure MST is:
* Split your set of VLANs into more instances and configure different MST settings for each of these instances. In order to easily achieve this, elect Bridge D1 to be the root for VLANs 501 through 1000, and Bridge D2 to be the root for VLANs 1 through 500. These statements are true for this configuration:
Switch D1(config)#spanning-tree mst configuration
Switch D1(config-mst)#instance 1 vlan 501-1000
Switch D1(config-mst)#exit
Switch D1(config)#spanning-tree mst 1 priority 0
Switch D2(config)#spanning-tree mst configuration
Switch D2(config-mst)#instance 2 vlan 1-500
Switch D2(config-mst)#exit
Switch D2(config)#spanning-tree mst 2 priority 0
The above commands create two MST instances, 1 and 2, and map VLANs 501-1000 to instance 1 and VLANs 1-500 to instance 2. Then, they make switch D1 the root for instance 1 and switch D2 the root for instance 2.
The other options are incorrect because:
* A. Spanning-tree bpdu-guard setting is a security feature that disables a port if it receives a BPDU from an unauthorized device. It does not affect load balancing with MSTP.
* C. Spanning-tree CIST mapping is not a valid command. CIST stands for Common and Internal Spanning Tree, which is the spanning tree instance that runs within an MST region and interacts with other regions or non-MST switches.
* D. Spanning-tree root-guard setting is another security feature that prevents a port from becoming a root port if it receives superior BPDUs from another switch. It does not affect load balancing with MSTP.

Q29. What is a primary benefit of BSS coloring?

BSS color tags improve performance by allowing clients on the same channel to share airtime.

BSS color tags are applied to client devices and can reduce the threshold for interference

BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference

BSS color tags improve security by identifying rogue APs and removing them from the network.

Q30. How is Multicast Transmission Optimization implemented in an HPE Aruba wireless network?

“The optimal rate for sending multicast frames is based on the highest broadcast rate across all associated clients

When this option is enabled the minimum default rate for multicast traffic is set to 12 Mbps for 5 GHz

The optimal rate for sending multicast frames is based on the lowest broadcast rate across all associated clients.

The optimal rate for sending multicast frames is based on the lowest unicast rate across all associated clients.

Q31. List the firewall role derivation flow in the correct order

Q32. Which feature allows the device to remain operational when a remote link failure occurs between a Gateway cluster and a RADIUS server that is either in the cloud or a datacenter?

MAC caching

MAC Authentication

Authentication survivability

Opportunistic key caching

Q33. With the Aruba CX 6000 24G switch with uplinks of 1/1/25 and what does the switch do when a client port detects a loop and the do-not-disabie parameter is used?

Port status will be validated once status is cleared

An event log message is created.

The network analytics engine is triggered.

Port status led blinks in amber with 100hz.

Q43. What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)

AP1 will cache the client’s information and send it to the Key Management service

The Key Management service receives from AirMatch a list of all AP2’s neighbors

The Key Management service receives a list of all AP1 s neighbors from AirMatch.

The Key Management service then generates R1 keys for AP2’s neighbors.

A client associates and authenticates with the AP2 after roaming from AP1

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.

Configure global loop-protect disable timer.

Configure int 1/1/1-1/1/46 loop-protect re-enable-timer.

Configure global loop-protect re-enable-timer.

Q47. Which statement best describes QoS?

Determining which traffic passes specified quality metrics

Scoring traffic based on the quality of the contents

Identifying specific traffic for special treatment
