HPE Network Switching Associate Exam Sample Questions (Q87-Q92):

NEW QUESTION # 87
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: A

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.

Explanation:


NEW QUESTION # 89
Your colleague is installing a new HPE Aruba Networking CX 8100 switch in a data center in the default configuration. You monitor the peer switch port 1/1/1 status, connected with a 10Gb 3m DAC cable to the new switch, and validate that the cable is attached. The port remains down.
What should you suggest your colleague do so the port can come online?

Answer: B

Explanation:
The correct answer is B. Request to issue the command no shutdown on the port the DAC cable is connected to. On HPE Aruba Networking CX 8100 and similar data center switch platforms, interfaces are Layer 3 and disabled by default. HPE Aruba Networking AOS-CX IP Services documentation states that, by default, all interfaces on these platforms are Layer 3 and disabled, and its examples explicitly enable the interface with no shutdown. Therefore, even if a supported 10Gb DAC cable is physically attached and the peer switch port is monitored, the link will remain down until the CX 8100 interface is administratively enabled. Option A is not the best answer because the symptom is not that the DAC is in the wrong port; the default shutdown state explains the link-down condition. Option C is incorrect because switching enable is not the AOS-CX command used to bring the port online. Option D is incorrect because DAC cables do not require manual Tx
/Rx polarity swapping like separate fiber strands might. ( arubanetworking.hpe.com )


NEW QUESTION # 90
You are checking the interface details for an Access Point that cannot reach HPE Aruba Networking Central. After reviewing the following output, which statement is true?

Answer: A

Explanation:
The output shows the admin state is up, but the interface state and link state are down and it is
"Waiting for link," which indicates the physical link is not established on interface 1/1/16.


NEW QUESTION # 91
Based on the given output:

Which HPE Aruba Networking CX switch can be used to create this configuration?

Answer: A

Explanation:
The configuration shown enables VSX, which is supported only on CX switch platforms that provide VSX capabilities. Among the listed models, the CX 8100 series supports VSX and can be used to build this type of dual-switch configuration with an inter-switch link, keepalive, and VSX synchronization.
