正解：C
質問 # 32
Which CLI command verifies if high CPU usage is caused by excessive broadcast traffic?
- A. show interface counters broadcast
- B. show qos broadcast
- C. display broadcast statistics
- D. show traffic multicast
正解：A
解説：
The show interface counters broadcast command provides insights into excessive broadcast traffic, helping identify and mitigate network-wide performance degradation.
質問 # 33
Which two CLI commands are used to reset a trunk port to its default settings? (Select two)
- A. no switchport mode trunk
- B. reset trunk settings
- C. default interface
- D. clear trunk configuration
正解：A、C
解説：
The no switchport mode trunk and default interface commands remove trunk settings, restoring the port to its default configuration to fix misconfigurations.
質問 # 34
Which command ensures configuration changes persist after a reboot?
- A. commit apply
- B. copy running-config startup-config
- C. show system
- D. reload
正解：B
解説：
The copy running-config startup-config command saves active configuration changes, ensuring they remain in effect after a switch reboot.
質問 # 35
How would you describe the firmware upgrade process for an HPE Aruba Networking VSX cluster?
- A. During the upgrade, the vsx-syned process will stop synchronization while the software versions are mismatched
- B. During the upgrade, the vsx-syned process will continue synchronization while the software versions are mismatched
- C. After the upgrade, the vsx-syned process will continue synchronization, once vsx-upgrade commit is issued
- D. After the upgrade, the vsx-syned process can resume synchronization even if the switches are in a different firmware version
正解：A
解説：
During a VSX firmware upgrade, the vsx-syned process stops synchronization while the switches have mismatched software versions. Synchronization resumes once both switches run the same software.
VSX synchronization cannot continue while versions mismatch (contrary to options B and D).
Compatibility mode is not required before rebooting secondary switch (Option D incorrect).
This behavior ensures consistency and avoids split-brain during upgrades.

質問 # 45 
You are about to make a change to the HPE Aruba Networking CX switch in HPE Aruba Networking Central and are encountering the condition displayed above. What needs to be done to make a change to the switch with multi-edit?
- A. Override state
- B. Select configuration status and enable edit config
- C. Select the device in multi-edit and enable edit config mode
- D. Enable edit config mode using the gear icon
正解：D
解説：
To make configuration changes using multi-edit in Aruba Central when encountering the shown condition, you must enable edit config mode using the gear icon. This unlocks the configuration for editing and allows you to make batch changes safely.
Selecting configuration status or device in multi-edit alone is not sufficient.
Overriding state is not a standard approach in Aruba Central for editing configs.

質問 # 46 
Refer to the exhibit for an HPE Aruba Networking CX 6300M VSF:
What VSF configuration is required for the stack configuration to work and avoid split-brain?
- A. vsf conductor-member 2
- B. vsf secondary-member 2
- C. vsl split-detect mgrep
- D. vsf start-auto-stacking
正解：C
解説：
To avoid split-brain scenarios in VSF stacks, the VSL split-detect mgrep command is used to enable multicast group detection over the Virtual Switching Link (VSL). This helps detect when the stack links are down or partitioned, triggering appropriate failover or shutdown mechanisms.
Options like vsf start-auto-stacking, vsf secondary-member 2, or vsf conductor-member 2 are related to stack initialization and member roles but do not address split-brain detection directly.
Hence, enabling split-detect with mgrep is the best practice for VSF stack stability.

質問 # 47
You are configuring OSPF between two CX switches but cannot see any neighbors. Based on the output, how would you fix the problem?
- A. Configure no passive-interface vlan182 on the switch.
- B. Configure no ip ospf cost 100 on the VLAN 182 interface.
- C. Configure ip ospf network broadcast on the VLAN 182 interface.
- D. Remove the max-metric router-lsa on-startup to allow faster formation of adjacency.
正解：A
質問 # 48
Which CLI command configures an Aruba CX switch to use Syslog for remote logging?
- A. syslog enable 192.168.1.100
- B. log-server 192.168.1.100
- C. logging host 192.168.1.100
- D. enable remote logging
正解：C
解説：
The logging host command configures a Syslog server, allowing centralized log collection for network event monitoring, security analysis, and troubleshooting.
質問 # 49
Examine the network topology.
The network is configured for OSPF with the following attributes:
* Core1 and Core2 and ABRs
* Area 1 has 20 networks in the 10.1.0.0/16 range
* Area 0 has 10 networks in the 10.0.0.0/16 range
* Area 2 has 50 networks in the 10.2.0.0/16 range
* The ASBR is importing a static route into Area 1
* Core2 has a summary for Area 2: area 0.0.0.2 range 10.2.0.0/16 type inter-area Here is the OSPF configuration performed on Core1:
Based on the above information, what is correct?
- A. Area 1 has 23 routes
- B. Core1 has received one LSA Type 5 from the ASBR
- C. Core1 has no OSPF routes
- D. Area 0 has 13 routes
正解：C
解説：
Because with "passive interface default" you would need a no passive interface on the Vlan 10 and Vlan 100 interfaces for neighborhoods to be established.
質問 # 50
You are troubleshooting a complex routing issue after a recent change. Your customer has just called and reported that the issue now impacts all users. What should you do next?
- A. Collect a show tech and log a case with TAC.
- B. Restore the last-known working configuration.
- C. Ask the customer to send logs from each user.
- D. Explain to the customer what the issue is.
正解：B
解説：
When a recent routing change causes an outage affecting all users, the recommended immediate action is to restore the last-known working configuration to quickly return the network to a stable state. This is critical to minimize downtime and impact.
Asking customers to send logs or explaining the issue takes time and delays remediation.
Collecting show tech and opening TAC cases can be done after restoring service.
Hence, the quickest way to mitigate the impact is to restore the last known good configuration.
