HPE6-A86 Exam Questions

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.

The correct answer is C. Lowest administrative distance. When a switch learns multiple possible routes to the same destination, it must select the preferred or best route to install and use for forwarding. HPE Aruba Networking documentation explains that administrative distance is one of the main criteria used to determine the preferred route when multiple paths exist to the same destination. The route with the lower administrative distance takes precedence. This is why connected routes, static routes, and dynamically learned routes can be preferred differently depending on their administrative distance values. Option A is incorrect because a default route is used only when no more specific route exists. Option B is incorrect because a static route is not automatically selected merely because it is static; it is preferred only if its administrative distance and route specificity make it the best candidate. Option D is incorrect because the highest administrative distance is less preferred, not more preferred.

The correct answer is D. SNMPv3. HPE Aruba Networking AOS-CX hardening documentation recommends using SNMPv3 instead of older SNMP versions because older SNMP versions are unauthenticated and unencrypted, with the community string transmitted in plaintext. The same guide states that SNMPv3 supports different users, authentication, and strong encryption. This makes SNMPv3 the secure protocol among the options. HTTP is not the best answer because standard HTTP does not encrypt management or web traffic; HTTPS would be the secure alternative. TFTP is not secure because it does not provide encryption or strong authentication for file transfers. Telnet is also not secure because it sends session traffic, including login information, in clear text; SSH is the secure alternative for CLI management. Therefore, from the listed protocols, only SNMPv3 provides security mechanisms appropriate for secure network management, including authenticated and encrypted communication.

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.

The correct answer is D. VSF stacking is supported within the same switch family members. HPE Aruba Networking AOS-CX VSF documentation states that a VSF stack supports combinations of models only within a supported switch family. For example, supported 6200 family models can stack with other supported 6200 family models, and supported 6300 family models can stack with other supported 6300 family models. The documentation also states that stacking is not supported across switch families. This means a VSF stack cannot mix unrelated platforms, such as chassis and fixed switches, or combine older AOS-S/Provision switches with AOS-CX switches in the same VSF stack. Option A is incorrect because VSF does not use proprietary backplane cabling; it uses supported Ethernet links, and the supported speeds depend on the switch family. Option B is incorrect because chassis and fixed platforms are not mixed in one VSF stack. Option C is incorrect because existing Provision/AOS-S switches cannot simply add CX switches as members in the same VSF stack.
