HPE7-A01 Aruba Certified Campus Access Professional Exam Practice Test

Answer : C

This is because option C shows how to create a single group in Central with different configuration methods defined for each device type. For example, you can create a group with the name Group1, and within this group, you can enable template-based configuration method for switches and UI-based configuration method for Instant APs and Gateways. Aruba Central identifies both these groups under a single name (Group1). If a device type in the group is marked for template-based configuration method, the group name is prefixed with TG (TG Group1).You can use Group1 as the group ID for workflows such as user management, monitoring, reports, and audit trail2.

Answer : A

The persona role option that should be selected to deploy a Gateway and take advantage of all the SD-WAN features is A. ArubaOS 10 Branch.

ArubaOS 10 Branch is a persona that enables the Gateway to provide both LAN and WAN functionality for branch networks. The Gateway can act as a wireless controller, a router, a firewall, and an SD-WAN device. The SD-WAN features include route and tunnel orchestration, dynamic path steering, forward error correction, SaaS traffic optimization, SASE orchestration, and more1.

The other options are incorrect because:

B) ArubaOS 10 VPN Concentrator: This is a persona that enables the Gateway to act as a VPN concentrator for remote access or site-to-site VPN connections. It does not provide SD-WAN features2.

C) ArubaOS 10 Wireless: This is a persona that enables the Gateway to act as a wireless controller for campus networks. It does not provide SD-WAN features3.

D) ArubaOS 10 Mobility: This is a persona that enables the Gateway to act as a mobility controller for campus networks. It does not provide SD-WAN features.

Answer : A

The standard that is supported by some Aruba APs and can enable a customer to accurately locate wireless client devices within a few meters is

A) 802.11mc.

802.11mc is an IEEE standard that enables computing devices to measure the distance to nearby Wi-Fi access points using a technique called Fine Timing Measurement (FTM). FTM uses precise timestamps to calculate the round-trip time of Wi-Fi frames between the device and the access point, and then converts it to a distance estimate. By using multiple access points and triangulation methods, the device can determine its location with high accuracy1.

According to the Aruba document 802.11mc Support, this feature is supported on 500 Series, 510 Series, 530 Series, 550 Series, 560 Series and 570 Series access points. These APs act as FTM responders to time measurement queries sent from a client. To configure the AP to send FTM responses, you need to enable the ftm-responder-enable parameter in the WLAN SSID profile1.

Answer : A

The capability that enables plug-and-play provisioning of access points in an HPE Aruba network is the UCC Service. The UCC Service is a cloud-based service that allows the access points to automatically discover and connect to the Aruba Central management platform without any manual intervention. The UCC Service also provides zero-touch configuration, firmware updates, and monitoring for the access points1.

The other options are incorrect because:

B) LLDP-MED: LLDP-MED is a protocol that enhances the interoperability between network devices and IP phones. It does not enable plug-and-play provisioning of access points2.

C) SRTP: SRTP is a protocol that provides encryption and authentication for voice and video traffic. It does not enable plug-and-play provisioning of access points3.

D) CSMA: CSMA is a protocol that regulates how devices share a common medium, such as a wireless channel. It does not enable plug-and-play provisioning of access points.

Answer : B

The correct answer is B. An event log message is created.

The do-not-disable parameter is used to prevent the switch from disabling the port when a loop is detected by the loop-protect feature. Instead, the switch will generate an event log message that indicates the port number and the VLAN ID where the loop was detected. The switch will also send a trap to the SNMP manager, if configured1.

The other options are incorrect because:

A) Port status will not be validated once status is cleared. The port will remain enabled even if a loop is detected, unless the loop-protect action is changed to tx-disable or tx-rx-disable1.

C) The network analytics engine will not be triggered by a loop detection. The network analytics engine is a feature that allows users to monitor and troubleshoot network issues using scripts and agents2.

D) Port status LED will not blink in amber with 100Hz. The port status LED will indicate the normal port status, such as link speed and activity, regardless of the loop detection3.

Answer : C

Authentication survivability is a feature that 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. Authentication survivability enables the Gateway cluster to cache successful authentication requests from the RADIUS server and use them to authenticate clients when the RADIUS server is unreachable. Authentication survivability also allows clients to use MAC caching or MAC authentication bypass (MAB) methods to access the network when the RADIUS server is down.

Answer : B

OSPF (Open Shortest Path First) is a routing protocol that uses link-state information to calculate the best path to each destination in the network.OSPF establishes adjacencies with neighboring routers to exchange routing information and maintain a consistent view of the network topology1.

To establish an OSPF adjacency, the routers need to have some common parameters, such as the area ID, the network type, the hello interval, the dead interval, and the authentication method2.The routers also need to have a matching subnet mask on the interface that connects them3.

In this case, the Aruba CX 6300 VSF stack has an SVI (Switched Virtual Interface) on VLAN 10 with an IP address of 10.1.1.1/24 and a LAG (Link Aggregation Group) on port 1/1/1 and port 2/1/1 that connects to a neighboring device. The SVI is configured with OSPF area 0 and network type broadcast. The LAG is configured with OSPF passive mode, which means that it will not send or receive OSPF hello packets.

The neighboring device has an interface with an IP address of 10.1.1.2/24 and a LAG on port 1/0/1 and port 2/0/1 that connects to the Aruba CX 6300 VSF stack. The interface is configured with OSPF area 0 and network type broadcast.

Since the Aruba CX 6300 VSF stack and the neighboring device have the same area ID, network type, subnet mask, and default hello and dead intervals on their interfaces, they will be able to establish an OSPF adjacency over SVI 10 with LAG 1. The OSPF passive mode on the LAG will not affect the adjacency, because it only applies to the LAG interface, not the SVI interface.
