HPE Network Switching Associate Exam Sample Questions (Q13-Q18):

NEW QUESTION # 13
A newly connected 500 Series access point is not visible in HPE Aruba Networking Central. You have run the following commands to troubleshoot:
Access-1# show run int vlan 10
interface vlan10
description Infrastructure Management
ip address 10.80.10.1/24
ip helper-address 10.200.10.51
exit
Access-1# show run int 1/1/1
interface 1/1/1
no shutdown
description Access Point
vlan trunk native 10
vlan trunk allowed 10,20,30
exit
Access-1# show lldp neighbor-info 1/1/1
Port : 1/1/1
Neighbor Entries : 1
Neighbor System-Name : b8:37:b2:5f:21:21
Neighbor System-Description : ArubaOS (MODEL: AP-505R), Version Aruba IAP Neighbor Management-Address : 169.254.2.58 Neighbor Port-ID : b8:37:b2:5f:21:21 Neighbor Port-DESC : eth0 Based on the output, what could be the problem?

Answer: A

Explanation:
The correct answer is C. The DHCP server has run out of leases. The key clue is the LLDP neighbor management address of 169.254.2.58. A 169.254.x.x address is a link-local address, which indicates the AP did not successfully receive a usable DHCP address from the intended management VLAN. The switch configuration shows VLAN 10 has an SVI address of 10.80.10.1/24 and an ip helper-address 10.200.10.51, so the DHCP server does not need to be in the same subnet as the AP. HPE Aruba Networking AOS-CX documentation explains that DHCP relay forwards DHCP messages from clients on a subnet without a local DHCP server to DHCP servers on other subnets and relays answers back to clients. Therefore, option B is incorrect. Option A is incorrect because Aruba APs support DHCP for address assignment. Option D is not the best answer because the AP is on the native VLAN of a trunk, which can carry untagged management traffic while also allowing additional VLANs. The likely issue is DHCP service failure, such as no available leases.


NEW QUESTION # 14
Which user group exists by default on an HPE Aruba Networking CX 8400 Series switch?

Answer: B

Explanation:
The correct answer is A. operators. HPE Aruba Networking AOS-CX documentation for the CX 8400 identifies built-in user groups that exist by default on the switch. These include administrators, operators, and auditors. The operators group has limited privileges, such as basic display-only CLI access and the ability to view nonsensitive switch configuration information. It does not have full switch configuration privileges. The other options-helpdesk, servicedesk, and support-are not listed as built-in default user groups for the CX
8400. Those names could be created manually as custom local user groups in some environments, but they are not default AOS-CX groups. Therefore, from the available choices, the default group is operators.


NEW QUESTION # 15
A Network Operator is analyzing a firewall log and sees an entry showing that a connection was denied. The log entry includes the following information: SRC_IP: 10.1.1.50, DST_IP:
172.16.5.100, DST_PORT: 80, PROTOCOL: TCP.
What is the primary function of the destination port number (80) at Layer 4 in this context?

Answer: D


NEW QUESTION # 16
A Network Operator is managing an HPE Aruba Networking CX switch using the command-line interface (CLI). The operator makes several configuration changes to a VLAN and wants to save these changes so they will be reapplied if the switch reboots. Which command saves the current, active `running-config` to the permanent `startup-config`?

Answer: B


NEW QUESTION # 17
A Network Technician is troubleshooting an intermittent connectivity issue on a copper link. The technician suspects the problem might be related to the cable itself. Which of the following represents a physical (Layer 1) problem?

Answer: D
