HPE Campus Access Switching Expert Written Exam 認定 HPE7-A06 試験問題 (Q12-Q17):

質問 # 12
The clientwouldlike to automate the process of troubleshooting issues to have better visibility. Which solution would you recommend for your client?

正解：C

解説：
The client wants to automate troubleshooting processes and gain better visibility into their network. We need to identify the recommended Aruba solution.
* Analysis of Options:
* A. HPE Aruba Networking Fabric Composer: A tool primarily for data center fabric provisioning and management, not general campus troubleshooting automation.
* B. HPE Aruba Networking Switch Multi-Edit Software: Likely refers to configuration management features (e.g., in Central or NetEdit) for applying changes to multiple switches, not primarily focused on automated troubleshooting or visibility.
* C. Automate processes with scripting like Python: AOS-CX supports on-box scripting (NAE) and REST APIs, enabling custom automation for monitoring and troubleshooting. While powerful, it requires development effort.
* D. AIOps integrated into HPE Aruba Networking Central: Aruba Central's AIOps capabilities are specifically designed to enhance visibility and automate aspects of troubleshooting. It uses AI
/ML to analyze network data, detect anomalies, provide insights into potential issues, correlate events, and offer prescriptive recommendations, directly addressing the client's need for better visibility and automated assistance with troubleshooting.
* Conclusion:While custom scripting (C) allows automation, Aruba Central AIOps (D) is the platform- integrated solution specifically marketed and designed by HPE Aruba Networking to provide enhanced visibility and automated insights fortroubleshooting campus networks. It is the most direct and recommended solution among the options for achieving these goals within the Aruba ecosystem.
References:Aruba Central documentation (AIOps features), AOS-CX NAE and REST API documentation.
This relates to "Troubleshooting" (10%) and "Performance Optimization" (6%) objectives.


質問 # 13
Refer to the exhibit.



When enabling DHCPv4-snooping on an AOS-CX access switch, which change has to be made to be able to get an IP from the DHCP-servers?

正解：B

解説：
To allow clients in VLAN 120 to obtain IP addresses, the switch must trust the interfaces connected to the upstream DHCP servers. The correct configuration is:
interface 1/1/51-1/1/52
dhcpv4-snooping trust
This ensures DHCP offers and acknowledgments from the servers on those ports are not dropped by DHCP snooping.


質問 # 14
Exhibit.

Acme Corp has VM workload running from ToR-1. and has noticed performancedegradation They suspect ToK-1 uplinks are periodically overutilized. List valid reasons whyToR-1 uplinks 3re being overutilized based on the diagram. (Select two.)

正解：B、D

解説：
The question involves Acme Corp experiencing performance degradation due to overutilized uplinks from ToR-1 to Core-1 and Core-2, with a diagram (not provided) indicating a potential MSTP (Multiple Spanning Tree Protocol) issue. The task is to identify valid reasons for uplink overutilization.
* Analysis of Options:
* Option A:Incorrect. Incorrect root bridge configuration (e.g., Core-2 as root) may cause suboptimal paths but is not directly linked to uplink overutilization without further context.
* Option B:Correct. Inconsistent VLAN-to-instance mappings across switches can cause MSTP to block unexpected ports, funneling traffic through fewer uplinks and causing overutilization.
* Option C:Incorrect. Firmware mismatches may cause compatibility issues but are unlikely to directly cause uplink overutilization.
* Option D:Correct. Using the default MSTP region configuration (e.g., default region name and revision) across switches can lead to all switches forming a single MSTP region, potentially causing suboptimal topology and uplink overuse.
* Option E:Incorrect. Running MSTP with admin-network port-type on uplinks and downlinks is not a standard cause of overutilization; it's a specific port role.
* Why B and D are Correct:MSTP relies on consistent region configurations (region name, revision number, VLAN-to-instance mappings) to create efficient topologies. If VLAN-to-instance mappings differ (Option B), switches treat each other as separate regions, leading to blocked ports and traffic concentration on fewer uplinks, causing overutilization. Similarly, using the default MSTP region configuration (Option D) without customizing the region name or revision can result in all switches forming a single region with suboptimal spanning tree instances, potentially overloading specific uplinks. Both issues disrupt MSTP's ability to balance traffic across redundant paths, aligning with HPE Aruba Networking's MSTP troubleshooting scenarios.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Troubleshooting MSTP for redundancy and fault tolerance.
* Switching (19%):Diagnosing Layer 2 issues, including MSTP misconfigurations.
* Performance Optimization (6%):Remediating uplink utilization issues.

質問 # 15
Two CX 8325 switches are configured as a cluster using VSX for the coreroleand two CX 6300M in VSF for theaggregation role. When a minor software upgrade is issued on the switches, what isthe method to achieve a hitlessupgrade with the aggregation switches?

正解：D

解説：
The question involves a minor software upgrade on a VSF (Virtual Switching Framework) stack of CX
6300M switches in the aggregation role, with CX 8325 switches in a VSX cluster as the core. The task is to identify the method for a hitless upgrade on the aggregation switches.
* Analysis of Options:
* Option A:Correct. VSF upgrades start with the secondary switch, followed by the primary, to ensure continuous operation without traffic disruption.
* Option B:Incorrect. In-Service Software Upgrade (ISSU) is used for VSX, not VSF, and follows a different process.
* Option C:Incorrect. Upgrading the primary switch first in VSF risks disrupting control plane operations.
* Option D:Incorrect. ISSU is not applicable to VSF upgrades.
* Why Option A is Correct:In a VSF stack, the update-software command initiates a rolling upgrade, starting with the secondary (standby) switch to ensure the primary (commander) continues handling traffic. Once the secondary is upgraded and rejoins the stack, the primary is upgraded, maintaining hitless operation. This process leverages VSF's ability to keep member switches active during upgrades, minimizing downtime. The CX 6300M's VSF implementation supports this hitless upgrade mechanism, as per HPE Aruba Networking documentation.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Designing and troubleshooting VSF for high availability and hitless upgrades.
* Troubleshooting (10%):Ensuring minimal disruption during software upgrades in campus networks.

質問 # 16
The user's device is failing 802.1 Xwith EAP-TLS authentication. We know that theclient-side certificate is valid. What is the likely cause of this issue? (Select two.)

正解：B、E

解説：
The user's device fails 802.1X EAP-TLS authentication, but the client-side certificate is known to be valid.
We need two likely causes.
* EAP-TLS Process:Involves mutual certificate validation and TLS handshake between client and RADIUS server (proxied by NAD).
* Causes (Client Cert OK):
* Server Certificate Issues: Client doesn't trust server cert (Untrusted CA, name mismatch, expired).
* EAP Type Mismatch:Client supplicant configured for different EAP type than RADIUS server policy.
* RADIUS Server Issues:Policy misconfiguration, user not found, internal errors.
* NAD <-> RADIUS Communication Failure:Switch cannot reach RADIUS server (IP connectivity, firewall, routing), incorrect shared secret.
* Client Supplicant Misconfiguration:Incorrect identity, settings other than the certificate itself.
* Network packet loss.
* Analysis of Options (Select Two):
* A: Wrong gateway affects L3 post-authentication.
* B: ACL blocking EAPoL/RADIUS is possible but less common than config errors.
* C:EAP-type mismatch:A very common configuration error leading to failure.
* D: Wrong MAC address is irrelevant for EAP-TLS failure itself.
* E: NAD not able to communicate with DNS servers: DNS isn't directly involved in EAP-TLS.
However, if interpreted more broadly asNAD not able to communicate with the RADIUS server(due to IP routing, firewall, or incorrect server address), this is a very common cause of failure.
* Conclusion:An EAP-type mismatch (C) is a prime suspect when basic certificate validity is assumed.
Failure of the Network Access Device (NAD - the switch) to communicate with the RADIUS server (E, interpreted broadly as RADIUS reachability) is another major category of failure causes.
