HPE6-A86 Exam Dumps - HP Aruba Certified Switching Associate (ACSA) V1 Questions and Answers

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 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.

The correct answer is A. Output of show tech. HPE Aruba Networking support and diagnostics documentation commonly uses technical-support command output as a key troubleshooting artifact for TAC analysis. The documentation specifically states to check physical cabling and generate show tech when opening a TAC case. The purpose of show tech output is to collect a broad set of switch operational details, including configuration, system status, interface information, logs, and other diagnostic data that can help TAC understand the condition of the device at the time of the issue. Option B is incorrect because “generated support keys” are not the standard required item from the listed choices for opening a CX switch TAC case. Option C is incorrect because TAC does not normally require open SSH access over the Internet, and exposing management access publicly would be poor security practice. Option D is incorrect because TAC may ask for software version information, but a copy of the running firmware image itself is not the first diagnostic item to prepare. The best initial evidence is the show tech output.

The correct answer is D. It is available as a cloud solution. HPE Aruba Networking Central is described in official Aruba documentation as a cloud-based management platform for managing AOS-CX infrastructure. It provides centralized functions for provisioning, configuring, monitoring, and troubleshooting AOS-CX switches. This means it is not limited to on-premises deployment. Option A is incorrect because AOS-CX support in Aruba Central is not limited only to templates; Central also supports monitoring, troubleshooting, and UI-based workflows depending on the software version, group type, and deployment model. Option B is also incorrect because monitoring-only mode is one supported option, but it is not the only supported mode. HPE Aruba documentation specifically notes that AOS-CX switches can be added in monitoring-only mode, but also separately documents configuration using templates and UI groups. Therefore, the broad and correct description for a customer conversation is that HPE Aruba Networking Central is available as a cloud management solution for AOS-CX switches.

The correct answer is B. TCP port. The Transport Layer, Layer 4 of the OSI model, is responsible for end-to-end transport services between hosts. TCP and UDP operate at this layer, and TCP/UDP port numbers identify application conversations on a host. A TCP port is therefore a Layer 4 item. Option A is incorrect because an IP address belongs to Layer 3, the Network Layer, where logical addressing and routing occur. Option C is incorrect because a MAC address belongs to Layer 2, the Data Link Layer, where Ethernet switching and local delivery are handled. Option D is incorrect because a physical switch port is associated with the Physical Layer interface and Layer 2 switching behavior, not the Transport Layer. In HPE Aruba Networking CX configurations, ACLs also distinguish between IP addressing and Layer 4 protocol fields such as TCP or UDP ports, reinforcing that TCP port information is transport-layer information.

A new firewall rule has been added = Cause

My email is not working = Symptom

My device says “No Internet” = Symptom

One of the DNS servers is offline = Cause

The switch firmware was upgraded = Cause

Websites are not loading = Symptom

The correct classification separates observed user impact from likely reasons for that impact. A symptom is what users or administrators observe, such as “email is not working,” “No Internet,” or “websites are not loading.” These describe the effect of the problem but do not identify why it is happening. A cause is a condition, change, or failure that could explain the symptom. A newly added firewall rule could block traffic, an offline DNS server could prevent name resolution, and a firmware upgrade could introduce a configuration, compatibility, or service-change issue. HPE Aruba Networking troubleshooting documentation commonly separates symptoms from causes and corrective actions; for example, AOS-CX troubleshooting sections describe a visible symptom, then identify the cause and action needed to resolve it. This method helps avoid guessing and keeps troubleshooting structured: first collect symptoms, then identify recent changes and infrastructure failures that could be possible causes. In this question, the user-facing service failures are symptoms, while the firewall, DNS, and firmware items are possible causes.

The correct answer is D. UDP 162. SNMP monitoring commonly uses two different UDP ports depending on direction and purpose. SNMP polling requests and responses use UDP 161, while SNMP traps and notifications are sent to a monitoring or management station on UDP 162. The question specifically asks about sending monitoring alerts using SNMP, which refers to SNMP traps or notifications from the switch to the Network Monitoring System. HPE Aruba Networking AOS-CX SNMP documentation states that the snmp-server host command configures a trap or inform receiver to which the SNMP agent sends SNMP traps or informs. The same documentation identifies the UDP port parameter for notifications and lists the default as 162. Therefore, the required firewall allowance for SNMP alert notifications from CX switches to the NMS is UDP 162. Option A is incorrect because TCP 161 is not the standard SNMP polling transport. Option B and option C use incorrect ports and protocols for SNMP alert delivery.

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.

The correct answer is B. Member 2 becomes Conductor. In the shown VSF stack, member 1 is currently the Conductor, member 2 is the Standby, and member 3 is a regular Member. HPE Aruba Networking VSF documentation explains that the Conductor runs the control plane for the VSF stack, while the Standby keeps a synchronized copy of the Conductor’s configuration database. If the Conductor fails or reboots, the Standby takes over the Conductor role to maintain stack operation. Since the output explicitly shows member 2 as the Standby, member 2 is the member expected to become the new Conductor when member 1 reboots. Option A is incorrect because member 2 is already Standby before the reboot. Option C is incorrect because member 3 is only a normal Member and would not take over while a Standby exists. Option D is not the best answer because the immediate role transition asked by the question is the Standby becoming Conductor.
