The correct answer is B. HPE Aruba Networking Central has been manually disabled on the switch. The key line in the output is Central admin state : disabled. HPE Aruba Networking AOS-CX documentation for the show aruba-central command provides an example of a switch when Aruba Central is disabled, showing Central admin state : disabled, Central connection values as N/A, and Central support mode as disabled. This indicates that the switch’s Central administrative state is disabled, so it is not attempting to connect to HPE Aruba Networking Central. Option A is incorrect because the VRF for connection : N/A value is a result of Central being disabled, not proof that the management VRF does not exist. Option C is incorrect because this command output does not report support-contract validity. Option D is incorrect because the factory-default Central behavior is not what is being shown; the output specifically reflects Central being disabled. Therefore, the correct interpretation is that Central has been manually disabled on the switch. ( arubanetworking.hpe.com )

The correct answer is D. If the ZTP operation detects that the switch configuration is different from the factory-default configuration, the ZTP operation ends. HPE Aruba Networking AOS-CX documentation explains that the ZTP process starts when the switch boots with the factory-default configuration. During the ZTP process, if the switch detects that its configuration is different from the factory-default configuration, the ZTP operation ends and the switch must be configured at the installation site. This directly addresses the customer’s concern: ZTP is intended for new or factory-default switches, and it should not overwrite or change switches that have already been manually configured or deployed. Option A is incorrect because the end condition is not based on a TFTP server detecting a serial-number configuration file. Option B is incorrect because being added to Central is not the stated stopping condition. Option C describes force provisioning, which can intentionally start provisioning behavior, but it does not address the concern about protecting already configured switches.

The correct answer is B. There are more than 8 bits in the host portion. The subnet mask 255.255.254.0 converts to a /23 prefix because the first two octets, 255.255, represent 16 network bits, and the third octet value 254 represents seven more network bits. That gives 23 network bits total. IPv4 addresses are 32 bits long, so 32 minus 23 leaves 9 host bits. Since 9 is more than 8, option B is correct. HPE Aruba Networking documentation uses prefix length as CIDR subnet-mask notation and supports IPv4 prefix lengths from 1 to 32, matching the /23 interpretation. Option A is incorrect because “10.64” alone is not the full network portion for a /23 network. The actual network range is 10.64.0.0/23. Option C is incorrect because the broadcast address for 10.64.0.0/23 is 10.64.1.255, not 10.64.0.240. Option D is incorrect because 255.255.254.0 is /23, not /25.

The correct answer is B. 2. The diagram shows two VLANs: VLAN 10 and VLAN 20. In Ethernet switching, each VLAN represents a separate Layer 2 broadcast domain. HPE Aruba Networking documentation defines a VLAN as a single Layer 2 network that can be partitioned to create multiple distinct broadcast domains, isolated from each other unless traffic passes through a router or Layer 3 interface. In this diagram, PCs A and B are in VLAN 10, so they share one broadcast domain. PCs C and D are in VLAN 20, so they share a second broadcast domain. The Layer 3 switch has SVIs for VLAN 10 and VLAN 20, which allow routing between the two VLANs, but the SVIs do not merge the broadcast domains. They provide Layer 3 gateways for each VLAN. Therefore, the number of broadcast domains is based on the number of VLANs shown, not the number of PCs, switch links, or SVIs. Since there are two VLANs, there are two broadcast domains.

The correct answer is B. PoE is disabled on the interface. If there are no lights on the access point, the first issue to investigate is whether the AP is receiving power. HPE Aruba Networking 550 Series installation documentation identifies Power over Ethernet as a supported power source for the AP, including IEEE 802.3bt or 802.3at PoE. HPE Aruba Networking AOS-CX documentation for the CX 6000/6100 PoE command shows that per-interface power distribution can be enabled with power-over-ethernet and disabled with no power-over-ethernet. If PoE is disabled on the switch interface, the AP will not receive power from the Ethernet cable and therefore may show no LEDs. Option A is incorrect because a missing STP configuration would not prevent the AP from powering on. Option C is incorrect because failure to reach HPE Aruba Networking Central would occur after the AP is powered and network-connected. Option D is also incorrect because a wrong VLAN can prevent management or provisioning, but it would not normally stop the AP LEDs from turning on.

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.

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 )

The correct answer is D. show system. HPE Aruba Networking AOS-CX documentation describes the show system command as displaying general status information about the system. The official command example includes fields such as Vendor, Product Name, and Chassis Serial Nbr. These fields provide the switch make, model/product name, and serial number directly in the CLI session. Option A is not the best answer because show support-information is intended for collecting broader support and diagnostic information, not the most direct command for viewing the switch identity. Option B is not the normal user command for displaying switch make, model, and serial number. Option C is incorrect because configuration output shows switch configuration, not necessarily the hardware identity information requested. Therefore, the direct command to display make, model, and serial number is show system.

The correct answer is C. No, SSH and HTTPS are enabled by default. HPE Aruba Networking AOS-CX hardening documentation states that, in the factory-default state, AOS-CX switches have SSH enabled on TCP port 22 and Web UI/read-write REST API enabled on TCP port 443. For the CX 6200 switch series, these services are enabled on both the default and management VRFs. These are secure management protocols because SSH encrypts CLI sessions and HTTPS encrypts web-management sessions. The same HPE Aruba guidance also notes that connections to TCP port 80 are automatically redirected to TCP port 443, which means HTTP is not used as the insecure management method. Option A is incorrect because Telnet is insecure and is not the correct default secure management protocol. Option B is incorrect because Telnet is not the default management method. Option D is incorrect because HTTP connections are redirected to HTTPS. ( arubanetworking.hpe.com )
