Each question shows the correct answer and an explanation of why it is right
What describes the use of the Network Analytics Engine?
The correct answer is C. Automates root cause analytics. HPE Aruba Networking AOS-CX documentation describes the Network Analytics Engine, or NAE, as a framework within AOS-CX switches that automates the detection of issues and automates root cause analysis. NAE agents monitor switch resources, events, configuration, protocol states, and other operational data to help identify issues faster. This helps administrators move from manual troubleshooting to analytics-driven troubleshooting directly on the switch. Option A is not the best answer because NAE is not simply a feature that automatically creates tech-support diagnostic files. Option B is incorrect because automated configuration backups are not the main purpose of NAE. Option D is incorrect because NAE does not primarily create support events in the HPE Aruba Networking Support Portal. Its purpose is local switch analytics, issue detection, and root cause analysis. Therefore, the best description is that NAE automates root cause analytics.
Which statement describes static routing?
The correct answer is B. Suitable for basic Layer 3 networks. HPE Aruba Networking AOS-CX IP Routing documentation describes static routing as a method that can be used when the network topology is simple enough. Static routes are manually configured routes that tell the switch how to reach specific destination networks or where to send default traffic. This makes static routing useful for smaller, stable, or basic Layer 3 environments where the number of routes is limited and the topology does not change frequently. Option A is incorrect because static routing is normally predictable; the administrator explicitly defines the path. Option C is incorrect because static routing does not scale well to large or complex networks, since every required route must be manually maintained. Option D is incorrect because static routing does not automatically adapt to network failures across the whole network like a dynamic routing protocol can. Therefore, static routing is best described as suitable for basic Layer 3 networks.
How do you configure an in-band management IP address for the HPE Aruba Networking CX 4100i switch?
The correct answer is C. In-band management uses the production switching network rather than the dedicated out-of-band management port. For an HPE Aruba Networking CX 4100i switch, HPE Aruba Networking AOS-CX documentation states that configuring the in-band management interface begins by entering interface vlan 1. The guide then shows that the in-band management interface can be configured with DHCP or with a static IP address. Therefore, assigning ip address 10.10.10.10/24 under interface vlan 1 is the correct in-band management configuration from the choices. Option A is incorrect because interface mgmt is the out-of-band management interface, not in-band management. Option D is also out-of-band for the same reason. Option B is not the best answer because routing is not required under the VLAN interface for this in-band management IP configuration. The essential configuration is the VLAN interface with the static IP address
Which user group exists by default on an HPE Aruba Networking CX 8400 Series switch?
The correct answer is A. operators. HPE Aruba Networking AOS-CX documentation for the CX 8400 identifies built-in user groups that exist by default on the switch. These include administrators, operators, and auditors. The operators group has limited privileges, such as basic display-only CLI access and the ability to view nonsensitive switch configuration information. It does not have full switch configuration privileges. The other options---helpdesk, servicedesk, and support---are not listed as built-in default user groups for the CX 8400. Those names could be created manually as custom local user groups in some environments, but they are not default AOS-CX groups. Therefore, from the available choices, the default group is operators.
The customer plans to roll out new HPE Aruba Networking CX 6000 and CX 6100 switches to replace existing AOS-S switches. To make the deployment include fewer manual tasks, the customer has asked how Zero Touch Provisioning, or ZTP, would help with the transition.
Which statement about ZTP is correct?
The correct answer is D. A DHCP server must be configured with the required options. HPE Aruba Networking AOS-CX documentation explains that ZTP is used to automatically load a switch configuration from a server when the switch boots from a factory-default configuration. The AOS-CX Fundamentals Guide for the 4100i, 6000, and 6100 switch series states that ZTP supports DHCP standards and DHCP options, and that support is limited to the listed DHCP options for ZTP on AOS-CX. The same guide describes setting up ZTP on a trusted network by preparing the configuration, setting up a TFTP server, and configuring DHCP-related information. Option B is incorrect because the guide references TFTP, not SFTP, for the ZTP server workflow. Option C is incorrect because the listed process does not use SCP for the initial template download. Option A is misleading because ZTP is enabled only when the switch is in factory-default configuration; the key requirement is the DHCP-based provisioning environment with the proper options.
New IoT devices cannot obtain an IP address from a DHCP server at 10.200.1.51. Based on the output below, what should you configure to resolve the issue?
interface vlan100
description IoT
ip address 10.100.1.1/24
exit
interface 1/1/16
no shutdown
description Thermostat
vlan access 100
spanning-tree port-type admin-edge
exit
The correct answer is B. Configure an IP helper for the DHCP server. The IoT device is connected to VLAN 100, whose Layer 3 SVI is 10.100.1.1/24. The DHCP server is 10.200.1.51, which is in a different subnet. DHCP clients initially use broadcast messages to discover a DHCP server, and those broadcasts do not cross Layer 3 boundaries by default. HPE Aruba Networking AOS-CX documentation explains that DHCP relay forwards DHCP client requests to configured DHCP servers, and that the ip helper-address command defines the address of a remote DHCP server or relay agent. The documentation also states that IP helper addresses can be configured on Layer 3 interfaces, Layer 3 VLAN interfaces, and LAG interfaces. Therefore, the correct fix is to configure ip helper-address 10.200.1.51 under interface vlan100. Disabling STP is not appropriate and could create Layer 2 loop risk. A static route may be needed for reachability in some designs, but it does not relay DHCP broadcasts. Broadcast-to-unicast conversion is not the required AOS-CX DHCP relay configuration.
Which customer use case would be ideal for an HPE Aruba Networking Central On-Premises deployment?
The correct answer is C. Customers that do not allow cloud connectivity. HPE Aruba Networking Central On-Premises is intended for organizations that need Aruba Central-style management capabilities but cannot or do not want to place management data in the public cloud. Official HPE Aruba Networking Central On-Premises documentation describes it as a variant of HPE Aruba Networking Central that is deployed in the customer's own environment, while the Validated Solution Guide states that Central On-Premises is appropriate when security requirements disallow Internet connectivity. This makes it suitable for organizations with strict regulatory, security, data sovereignty, or internal policy requirements that prevent cloud-managed network infrastructure. Option A is incorrect because using hyperscaler-hosted server resources does not, by itself, require Central On-Premises. Option B is incorrect because a SaaS-maintained management platform describes the cloud version of HPE Aruba Networking Central, not the on-premises deployment. Option D is not the best answer because geographical redundancy is not the primary use case described for choosing Central On-Premises.
