HP HPE7-A08 Exam Syllabus Topics:

TopicDetails
Topic 1
  • Install and Configure the Wired Network Solution: This domain evaluates the abilities of Network Engineers to provision and configure HPE Aruba Networking switches both via Aruba Networking Central and command-line interface. It covers physical switch setup, Layer 2 and Layer 3 configuration and validation, multicast features, security implementations, quality of service (QoS) settings, and integration of Aruba Networking solutions into existing environments.
Topic 2
  • Create the Implementation Plan for the Wired Network Solution: This section measures the skills of Network Designers who focus on understanding the HPE switching portfolio and selecting the right products to match various customer requirements. Candidates must also demonstrate the ability to create detailed and effective implementation plans based on given designs or customer scenarios to ensure successful wired network deployments.
Topic 3
  • Manage, Maintain, Optimize, and Monitor the Wired Network Solution: This part measures the skills of Network Operations Engineers in managing and maintaining wired network infrastructures. It includes developing configuration management strategies, interpreting network operational data to make informed decisions, and programmatically auditing or configuring Aruba Networking switches to optimize performance and reliability.
Topic 4
  • Troubleshoot the Wired Network Solution: Candidates in this section, typically Network Support Specialists, are tested on identifying common wired network failures such as IP or VLAN mismatches, hardware issues, or port misconfigurations. It also involves analyzing performance problems caused by QoS or configuration errors and formulating effective remediation plans to restore correct network operations.

HPE Aruba Networking Switching Professional Exam Sample Questions (Q112-Q117):

NEW QUESTION # 112
How does PIM build the IP multicast routing table to route traffic between a multicast source and one or more receivers?

Answer: A

Explanation:
PIM also relies on the unicast routing tables to identify the path back to a multicast source. This routing method is known as reverse path forwarding (RPF). The unicast routing protocols create the unicast routing tables. With this information, PIM sets up the distribution tree for the multicast traffic.


NEW QUESTION # 113
Refer to the exhibit:

The interface is configured on an HPE Aruba Networking CX 8320 for a VMware server NIC, and the server admin reports that VMware vMotion traffic on VLAN 3903 fails, but the server can ping other ports with default settings.
What must be done to correct the issue based on the provided interface status and configuration?

Answer: D

Explanation:
The issue is VMware vMotion traffic on VLAN 3903 failing, while other VLANs work normally. vMotion traffic requires support for larger frame sizes (jumbo frames) because vMotion packets are large and benefit from increased MTU to improve performance and reduce fragmentation.
Configuring jumbo frames on VLAN 3903 ensures that frames on this VLAN can use an MTU larger than the default 1500 bytes.
Configuring jumbo on the interface alone may not be sufficient if the VLAN itself is not set to support jumbo frames.
Setting MTU on VLAN or interface might not work unless jumbo frames are enabled.

NEW QUESTION # 114
An Aruba CX B100 VSX has the following state for LACP:
2024-06-08T19:48:34.713434+03:00 VSX1 lacpd[837]: Event|1321|LOG_INFO|AMM|1/1|LAG

06T19:48:34.675496+03:00 VSX1 lacpd[837]: Event|1308|LOG_INFO|AMM|1/1|LACP rate set to slow for LAG 253 What can be observed based on the output?

Answer: A


NEW QUESTION # 115
Which statement is valid when enabling ARP protection features on HPE Aruba Networking CX switches?

Answer: A

Explanation:
When enabling ARP protection, it is best practice to wait at least a week after enabling DHCP snooping before enabling ARP protection in a live network. This allows the DHCP snooping binding table to stabilize, ensuring ARP protection has accurate IP-MAC bindings, reducing false positives.
Immediate ARP protection may cause legitimate traffic to be dropped.
Lease times and DHCP server utilization are less critical.
This staged approach minimizes disruption.

NEW QUESTION # 116
After enabling 802.1X authentication on all switch ports connected to AOS10 access points, users joining SSIDs in bridge mode no longer receive an IP address. Users of tunnel mode SSIDs are unaffected. What should be done to resolve the issue?

Answer: C

Explanation:
This scenario highlights a common conflict between Port Access Control and WLAN architectures in AOS10.
* Tunnel Mode vs. Bridge Mode: * In Tunnel Mode , client traffic is encapsulated (GRE/IPsec) from the AP to the Gateway. The switch port only sees the MAC address of the AP itself. Once the AP authenticates via 802.1X, all tunneled client traffic passes through the authenticated " tunnel " unnoticed by the switch ' s port security.
* In Bridge Mode , the AP bridges wireless client traffic directly onto the local VLAN. The switch port now sees the MAC addresses of the wireless clients.
* The Conflict: By default, an 802.1X port expects only one authenticated device. When the AP authenticates, the port is " open " for the AP ' s MAC. However, when a wireless client's bridged MAC appears on the same port, the switch treats it as an unauthenticated intruder and drops its DHCP requests.
* The Solution (Device Mode): You must configure the User Role assigned to the AP (after it authenticates) with device-mode (often referred to as dev-conf-mode or device auth-mode in exam contexts). This tells the switch: " The device that just authenticated is a trusted infrastructure device (an AP). Please allow all subsequent MAC addresses seen on this port to pass without requiring individual authentication. "
