HP Aruba Certified Campus Access Professional Exam 認定 HPE7-A01 試験問題 (Q37-Q42):

質問 # 37
You are helping an onsite network technician bring up an HPE Aruba Networking 9004 gateway with ZTP for a branch office. The technician was told to plug in any port for the ZTP process to start.
Thirty minutes after the gateway was plugged in, new users started to complain they were no longer able to get to the internet. One user who reported the issue stated their IP address is
172.16.0.81. However, the branch office network is supposed to be on 10.231.81.0/24.
What should the technician do to alleviate the issue and get the ZTP process started correctly?

A. Move the cable on the gateway to G0/0/1, and add the device's MAC and Serial number in Central
B. Turn off the DHCP scope on the gateway, and set DNS correctly on the gateway to reach Aruba Activate
C. Move the cable on the gateway from port G0/0/1 to port G0/0/0.
D. Factory default and reboot the gateway to restart the process.

正解：C

解説：
Aruba 9004 gateway supports ZTP on port G0/0/0 by default. If the gateway is connected to a different port, such as G0/0/1, it will not be able to communicate with Aruba Activate and Aruba Central, which are required for ZTP. Moreover, port G0/0/1 is configured as a DHCP server by default, which can cause IP address conflicts with the existing network. Therefore, the technician should move the cable on the gateway to port G0/0/0, which will allow the gateway to obtain an IP address from the network DHCP server and start the ZTP process.

質問 # 38
Your customer is having connectivity issues with a newly-deployed Microbranch group The access points in this group are online in Aruba Central, but no VPN tunnels are forming.
What is the most likely cause of this issue?

A. There is a time difference between the AP and the gateways The gateways should have NTP added
B. There may be a firewall blocking GRE tunneling between the AP and the gateway
C. The gateway group is running in automatic cluster mode and should be in manual cluster mode
D. The SSL certificate on the gateway used to encrypt the connection has not been added to the APs trust list

正解：B

解説：
This is the most likely cause of the issue where the access points in a Microbranch group are online in Aruba Central, but no VPN tunnels are forming. A Microbranch group is a group that contains both APs and Gateways and allows them to form VPN tunnels for secure communication. The VPN tunnels use GRE (Generic Routing Encapsulation) as the encapsulation protocol and IPSec as the encryption protocol. If there is a firewall blocking GRE traffic between the AP and the gateway, the VPN tunnels cannot be established.
The other options are incorrect because they either do not affect the VPN tunnel formation or do not apply to a Microbranch group. References: https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help

質問 # 39
A customer is using stacked Aruba CX 6200 and CX 6300 switches for access and a VSX pair of Aruba CX 8325 as a collapsed core 802 1X is implemented for authentication. Due to the lack of cabling, some unmanaged switches are still in use Sometimes devices behind these switches cause network outages The switch should send a warning to the helpdesk when the problem occurs You have been asked to implement an effective solution to the problem What is the solution for this?

A. Configure spanning tree on the Aruba CX 6200 and CX 6300 switches No trap option is needed
B. Configure loop protection on all edge ports of the Aruba CX 6200 and CX 6300 switches Set up the trap-option
C. Configure loop protection on all edge ports of the Aruba CX 6200 and CX 6300 switches No trap option is needed
D. Configure spanning tree on the Aruba CX 8325 switches Set the trap-option

正解：B

解説：
This is the correct solution to the problem of devices behind unmanaged switches causing network outages due to loops. Loop protection is a feature that allows an Aruba CX switch to detect and prevent loops by sending loop protection packets on each port, LAG, or VLAN on which loop protection is enabled. If a loop protection packet is received by the same switch that sent it, it indicates a loop exists and an action is taken based on the configuration. Loop protection should be configured on all edge ports of the Aruba CX 6200 and CX 6300 switches, which are the ports that connect to end devices or unmanaged switches. The trap-option should be set up to send a warning to the helpdesk when a loop is detected. The other options are incorrect because they either do not configure loop protection or do not set up the trap-option.

質問 # 40
Your manufacturing client is having installers deploy seventy headless scanners and fifty IP cameras in their warehouse These new devices do not support 802 1X authentication.
How can HPE Aruba reduce the IT administration overhead associated with this deployment while maintaining a secure environment using MPSK?

A. MPSK Local will allow the cameras to share a key and the scanners to share a different key
B. Use MPSK Local to automatically provide unique pre-shared keys for devices.
C. Have the MPSK gateway derive the unique pre-shared keys based on the MAC OUI.
D. Have the installers generate keys with ClearPass Self Service Registration.

正解：B

解説：
MPSK Local is a feature that can reduce the IT administration overhead associated with deploying devices that do not support 802.1X authentication while maintaining a secure environment. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require manual intervention by the installers or the MPSK gateway, or they do not provide unique pre-shared keys for devices. References:

質問 # 41
Which Aruba AP mode is sending captured RF data to Aruba Central for waterfall plot?

A. Hybrid Mode
B. Air Monitor
C. Dual Mode
D. Spectrum Monitor

正解：D

解説：
Spectrum Monitor is an Aruba AP mode that is sending captured RF data to Aruba Central for waterfall plot.
Spectrum Monitor is a mode that allows an AP to scan all channels in both 2.4 GHz and 5 GHz bands and collect information about the RF environment, such as interference sources, noise floor, channel utilization, etc. The AP then sends this data to Aruba Central, which is a cloud-based network management platform that can display the data in various formats, including waterfall plot. Waterfall plot is a graphical representation of the RF spectrum over time, showing the frequency, amplitude, and duration of RF signals. The other options are incorrect because they are either not AP modes or not sending RF data to Aruba Central.
