HPE Network Switching Associate Exam Sample Questions (Q126-Q131):

NEW QUESTION # 126
A Network Operator is setting up a new switch. A server is connected to port 1/1/1 and a user workstation to port 1/1/2. The switch has just been powered on and its MAC address table is empty. The user workstation (MAC: AAAA.AAAA.AAAA) sends a frame to the server (MAC:
BBBB.BBBB.BBBB).
What two actions will the switch take? (Choose 2.)

Answer: D,E


NEW QUESTION # 127
Refer to the diagram below. After a recent network change, the helpdesk reports that some users could not connect to the print server. Server-1, which is in VLAN 20. After further investigation, you find that only devices directly connected to Access-2 are affected. Which part of the network should you investigate?

Answer: A

Explanation:
Only clients connected to Access-2 are affected, while the server is also on Access-2 in VLAN 20.
This points to VLAN 20 not being consistently carried across the inter-switch trunk after the change, so traffic from some Access-2 user ports mapped to VLAN 20 would fail to reach Server-
1. Checking the trunk's allowed VLAN list between the access switches verifies whether VLAN 20 is permitted end-to-end.


NEW QUESTION # 128
Which command could you use to validate the status of the interfaces on the switch?

Answer: E


NEW QUESTION # 129
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: B


NEW QUESTION # 130
A CX 6200 VSF stack is the Layer 3 gateway for a mid-sized company. Users are divided into three different subnets on VLANs 100, 200, and 300. VLAN 50 contains a management network for access points, switches, and DHCP servers.
How do the access points get an IP address using DHCP?

Answer: C

Explanation:
The correct answer is D. As a response to the broadcast DHCP query. DHCP clients initially do not have an IP address, so they commonly use broadcast DHCP discovery/request traffic to locate a DHCP server on the local network. HPE Aruba Networking documentation for DHCP relay explains that when a DHCP client broadcasts a request, the DHCP relay agent on the switch receives the packets and forwards them to the DHCP server as unicast requests. In this scenario, the access points are in VLAN 50, and VLAN 50 also contains DHCP servers. Because the DHCP server is on the same local management VLAN as the APs, the APs can obtain addresses through the normal DHCP broadcast process within that VLAN. Anycast and multicast are not used for the basic DHCP address request in this scenario. A unicast DHCP relay message can occur between a relay agent and a DHCP server when the server is on another subnet, but the client-side DHCP discovery begins as broadcast traffic.
