HP HPE7-A07 Exam Practice Test Instant Access

Question 1

Your customer added third-party USB dongles to the USB ports of their AOS 10 access points. The customer uses AP-615 and AP-635 Each AP is connected with a Cat 6A cable to a CX 6300F Class 4 PoE switch All APs are in the same group in HPE Aruba Networking Central and share the same configuration However, many of the dongles do not come up.

Which option will solve this issue?

AReplace the Class a PoE switches with Class 6 PoE switches.

BCreate two separate service profiles in the loT tab of the Central configuration settings.

CPerform a 'poe disable' followed by a 'poe enable' for the switch ports which connect to the APs so that the APs reboot.

DMove the AP-635 access points to a different group in Central to configure the dongles separately from the AP-615.

Answer : A

USB dongles often require additional power, which may exceed the power delivery capabilities of Class 4 PoE switches. Aruba AP-615 and AP-635 are designed to work with USB dongles that require additional power for proper operation. Since the Cat 6A cable can support higher power levels, replacing the Class 4 PoE switches with Class 6 PoE switches, which can deliver higher power, should resolve the issue with the dongles not powering up.

Question 2

Exhibit.

A customer is reporting mat connectivity is Tailing for some wireless client Devices. What are your conclusions from the capture? (Select two.)

AThe client does not have an ARP entry for me default gateway.

BThe network is using WPA2-PSK key management.

CThe network is using WPA3-SAE key management.

DThe client is not receiving an IP address.

EThe client does not support beamforming.

Answer : B, D

The capture shows messages related to WPA key management, indicating WPA2-PSK is being used. Also, the capture includes a DHCP request from the client but no corresponding DHCP ACK, suggesting the client is not receiving an IP address, which could explain the connectivity failure.

Question 3

A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile cased on best practices. Why do they have an equal split of their 120 APs across the primary and secondary gateway clusters?

AThe primary gateway cluster is a heterogeneous cluster with six nodes.

BThe primary and secondary gateway clusters are up. and the cluster preemption is enabled

CThe secondary gateway cluster is a homogeneous cluster with six nodes.

DThe primary and secondary gateway clusters are up. but the cluster preemption Is not enabled

Answer : D

When cluster preemption is not enabled, access points (APs) will not automatically fail back to the primary gateway cluster once it is up again after having failed over to the secondary. This would result in an equal split of APs across primary and secondary clusters if both clusters are operational. Without preemption, there's no automatic rebalancing of APs back to the primary cluster, leading to the current distribution.

Question 4

A customer has recently deployed a wireless system using AP-535S to provide connectivity for their employees who are responsible tor uploading large video files for review. The customer wants to use features that provide throughput gains for large data uploads.

Which feature can be enabled to meet the requirement and simultaneously allow spatially separated clients access to the channel?

AUl-TXBF

BOFOMA

CDL MU-MIMO

DUL MU-MIMO

Answer : D

UL MU-MIMO, or Uplink Multi-User Multiple Input Multiple Output, is a technology that allows multiple clients to transmit data to the access point simultaneously, increasing overall throughput and efficiency, especially for upload-heavy scenarios like video file uploads. This technology enables spatially separated clients to access the channel at the same time, which can improve performance for clients when uploading large files.

Question 5

A network administrator wants to configure an 802 1X supplicant for a wireless network that includes the following:

1. AES encryption

2. EAP-MSCHAPv2-based user and machine authentication

3. validation of server certificate in Microsoft Windows 10

The network administrator creates a WLAN profile and selects the change connection settings option Then the network administrator changes the security type to Microsoft Protected EAP (PEAP) and enables user and machine authentication under Additional Settings.

What must the network administrator do next to accomplish the task?

AEnable user authentication

BChange the security type to Microsoft: Smart Card or other certificate.

CChange default RC4 encryption for AES

DEnable server certificate validation

Answer : D

When configuring an 802.1X supplicant for wireless network access with Microsoft Windows 10, enabling server certificate validation is a critical step to ensure the security of the authentication process. Server certificate validation helps prevent man-in-the-middle attacks by ensuring the RADIUS server presenting the certificate is the correct server that the client expects to communicate with.

Question 6

Which command would allow you to verity receipt of a CoA message on an AOS 10 GW?

Apacket-capture datapath udp 3799

Bpacket-capture controipath udp 3799

Cpacket-capture interprocess udp 3799

Dtcpdump host-port 3799

Answer : B

The Change of Authorization (CoA) messages are used in network access control scenarios and are typically received by the network access server, in this case, an Aruba AOS 10 Gateway. The correct command to verify the receipt of a CoA message is related to the control path traffic because CoA is a control plane function.

Option B, packet-capture controlpath udp 3799, is the correct answer because it specifies capturing control plane traffic on UDP port 3799, which is the standard port for CoA messages.

Options A, C, and D are incorrect because:

Option A captures data plane traffic, not control plane traffic.

Option C's packet-capture interprocess udp 3799 does not refer to a standard command for capturing CoA messages.

Option D, tcpdump host-port 3799, does not specify the correct syntax for capturing traffic on Aruba devices.

Question 7

Your customer asked for help to apply an ACL for wireless guest users with the following criteria:

* Wi-Fi guests are on VLAN 555

* allow internet access

* only allow access to public DNS servers

* deny access to all internal networks except for any DHCP server

These session ACLs are already present in the CLI of the mobility gateway group:

You have access to the CLl. Which user role meets all the criteria?

AOption A

BOption B

COption C

DOption D

Answer : A

Based on the criteria provided for wireless guest users, the correct user role configuration must allow internet access, only allow access to public DNS servers, deny access to all internal networks except for any DHCP server, and place the Wi-Fi guests on VLAN 555. The ACLs must permit services necessary for basic internet access (such as DNS and DHCP) and block access to internal networks.

Option A satisfies these criteria with the following configurations:

user-role 'WiFi-guest': This defines the role for Wi-Fi guests.

access-list session dhcp-acl: This applies the access list that likely permits DHCP, which is necessary for guests to obtain an IP address.

access-list session dns-acl: This applies the DNS access list, which likely restricts guests to using public DNS servers.

access-list session internal-networks: This applies the internal networks access list, which denies access to internal networks.

vlan 555: This sets the VLAN for Wi-Fi guests to 555.

Options B, C, and D are incorrect because they include access-list session allowall which would permit all traffic, contradicting the requirement to deny access to all internal networks.
