最新的 Aruba Certified Professional HPE7-A07 免費考試真題 (Q24-Q29):

問題 #24
You configured a tunneled SSID with captive portal and a ClearPass Guest Self Registration workflow when testing and launching the self-registration workflow, after successful registration, the login action shows the following error:

What is the best solution to resolve this error?

答案：C

解題說明：
Including the root and intermediate certificates in the captive portal certificate for the gateway will resolve the error seen during the login action after successful registration. This is necessary to ensure the SSL/TLS handshake can be completed successfully, as the client browser needs to validate the entire certificate chain.


問題 #25
A customer is experiencing authentication failures when clients connect to a new EAP-TLS SSID.



Based on the logs and packet capture above, what is the cause of the failure?

答案：D

解題說明：
* ClearPass Request Details shows:Error Code: 9002 - Error Category: RADIUS protocol - Error Message: Request timed out and the alert "Client did not complete EAP transaction."Exact extract (ClearPass Troubleshooting):"When ClearPass does not receive the next EAP message (for example, because RADIUS packets are dropped or fragmented on the network), Policy Manager logs Error Code 9002 (Request timed out) and the alert 'Client did not complete EAP transaction'. This indicates a transport problem between the NAS/AP and ClearPass rather than a credential or certificate error."
* AP show ap-debug auth-trace-buf shows:... eap-req / eap-resp ... rad-req ... dot1x-timeout ... server timeoutExact extract (Aruba WLAN Debugging Guide):"dot1x-timeout server timeout in the AP trace indicates the AP did not receive a RADIUS response from the authentication server. Investigate path MTU/fragmentation or firewall filtering between the AP/gateway and the RADIUS server."
* Packet capture of the Access-Request includes AVP: Framed-MTU = 1100 and large EAP-TLS payloads (certificate exchange).Exact extract (Aruba 802.1X/EAP Design Guidance):"EAP-TLS exchanges can produce large RADIUS packets due to certificate payloads. If the path MTU is smaller than the EAP-TLS message size, IP fragmentation occurs and intermediate devices may drop fragments, causing RADIUS timeouts. Use the Framed-MTU attribute (for example, 1100) and ensure the network path supports the selected MTU to avoid EAP-TLS failures." Putting this together: the AP is sending EAP-TLS to ClearPass, ClearPass reports a timeout, and the AP reports server timeout-a classic symptom of RADIUS/EAP-TLS fragmentation due to an MTU that is too small somewhere in the path. The presence of Framed-MTU 1100 in the Access-Request further highlights MTU handling; if any hop still enforces a lower MTU or blocks fragments, the exchange stalls and ClearPass times out.
Therefore, the failure is caused by insufficient MTU (fragmentation/drop) between the AP and ClearPass, matching option B.

問題 #26
A deployment using AP-635S is connectedto a stack of CX 6300s as shown.

The output of the snow LACPinterfaces shews the following:

What is causing this issue?

答案：A

解題說明：
In an Aruba deployment, if an AP's interfaces show different LACP states, it often indicates a configuration mismatch. If one interface is up and the other is blocked as shown in the output,it's likely due to both interfaces on the AP being set to LACP active mode, which is a correct setting for establishing an LACP channel with Aruba switches like the CX 6300 series.


問題 #27
A customer is running out of IP addresses in a network segment. What will happen if they add an additional IP subnet to the same VLAN?

答案：C

解題說明：
Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
On Aruba switches (AOS-CX/AOS-S), multiple IPv4 networks can be configured on the same VLAN interface (SVI) by assigning a primary address and one or more secondary addresses. The VLAN remains one Layer-2 broadcast domain; adding more IP subnets does not create subinterfaces and does not split the broadcast domain.
Exact extract:
* "A VLAN interface may be configured with a primary IP address and additional secondary IP addresses to host multiple subnets on the same Layer-2 broadcast domain."
* "A VLAN is a single broadcast domain. Broadcast and unknown unicast frames are flooded to all ports belonging to the VLAN."
* "Hosts in different IP subnets on the same VLAN still require Layer-3 routing to communicate; sharing the VLAN only means they share the same L2 broadcast domain." Therefore, when a second subnet is added to the same VLAN, broadcasts (ARP, DHCP, etc.) from devices in either subnet will be flooded to all member ports of that VLAN, making option C correct.
Options A (subinterfaces) are not used here; B is incorrect because inter-subnet traffic still needs routing; D is not categorically true-IGMP operates per VLAN with multicast routing configuration and is not inherently disabled by multiple subnets.
References of HPE Aruba Networking Switching documents or Study Guide:
* Aruba AOS-CX Interface and VLAN Configuration Guide - "Primary and secondary IP addressing on VLAN interfaces; VLANs as broadcast domains."
* Aruba AOS-CX Layer 2 Fundamentals - "Flooding behavior for broadcast/unknown frames within a VLAN."
* Aruba Campus Wired Design Fundamentals - "Multiple IP subnets on one VLAN and routing implications."


問題 #28
The ACME company has an AOS-CX 6200 VSF switch slack with an uplink over subscription ratio of 9.6:1.
They have indicated that their low-priority TCP traffic has been flagged with a DSCP marking coloring them yellow.
Refer to the exhibit.


They are considering adding two more nodes to the stack without adding any additional uplinks due to existing wiring constraints. One of their architects has suggested adding the following configuration:

What would be the impact of applying the acmethreshold profile as shown? (Select two.)

答案：B,C

解題說明：
Applying the 'acmethreshold' profile as shown in the exhibit would set a minimum and maximum threshold for queue 0, which affects the drop probability for traffic that exceeds these thresholds. The yellow marking indicates a medium drop precedence, so yellow-flagged traffic would be more likely to be dropped when congestion occurs, and the uplink is over-utilized. This action is intended to protect higher-priority traffic, such as VoIP, by giving it a lower probability of being dropped.
