The correct answer is A. A public CA signed certificate should be deployed. The browser warning appears because the captive portal is presenting a self-signed certificate that the client device does not trust. For guest access, client devices are usually unmanaged and cannot be expected to already trust an internal or self-signed certificate authority. HPE Aruba Networking documentation for captive portal deployments recommends that production environments obtain and install a certificate issued for the site or domain by a well-known Certificate Authority. This avoids browser trust warnings and gives guest users confidence that they are connecting to the correct portal. Option B is incorrect because disabling HTTPS and using HTTP would reduce security and expose portal traffic. Option C may work only for managed devices where the self-signed or private CA can be pushed into the trust store, but that is not practical for open wired guest access. Option D can be valid for internal managed users, but for guests, a public trusted CA certificate is the best answer.

The correct answer is A. A link between members 1 and 3 needs to be disconnected. The output shows that the current three-member VSF stack is built as a ring: member 1 connects to member 2, member 2 connects to member 3, and member 3 connects back to member 1. To insert an additional member into an existing physical ring, one of the ring links must be opened so the new switch can be cabled between the two existing members. In this case, disconnecting the link between members 1 and 3 allows the new member to be added between those members, preserving the ring topology after the new connections are made. HPE Aruba Networking VSF documentation states that VSF supports 6200F stacks in chain and ring topologies, with ring topology recommended for resiliency because each member has VSF link connectivity to two other members. Option B is incorrect because changing to chain topology is not required or preferred. Option C is incorrect because the existing VSF links are already being used for the ring. Option D is incorrect because the standby role is determined within the stack; the new member is not pre-provisioned as standby.

The correct answer is D. SNMPv3. HPE Aruba Networking AOS-CX hardening documentation recommends using SNMPv3 instead of older SNMP versions because older SNMP versions are unauthenticated and unencrypted, with the community string transmitted in plaintext. The same guide states that SNMPv3 supports different users, authentication, and strong encryption. This makes SNMPv3 the secure protocol among the options. HTTP is not the best answer because standard HTTP does not encrypt management or web traffic; HTTPS would be the secure alternative. TFTP is not secure because it does not provide encryption or strong authentication for file transfers. Telnet is also not secure because it sends session traffic, including login information, in clear text; SSH is the secure alternative for CLI management. Therefore, from the listed protocols, only SNMPv3 provides security mechanisms appropriate for secure network management, including authenticated and encrypted communication.

The correct answer is B. Push-to-talk radio. Half-duplex communication allows transmission in both directions, but not at the same time. A push-to-talk radio is a common example because one person presses the talk button and transmits while the other side listens; then the first person stops transmitting so the other person can reply. This differs from a telephone system, which is normally full-duplex because both parties can speak and hear at the same time. FM radio broadcast is simplex, because communication normally flows in only one direction from the broadcaster to receivers. A fibre-optic pair is commonly used for full-duplex communication because separate fibers or transmit/receive paths can support simultaneous sending and receiving. In HPE Aruba Networking switch documentation, duplex is discussed as a Layer 1/Layer 2 port characteristic, with half-duplex supported for some Ethernet speeds and full-duplex used for modern switched links. Therefore, the option that best represents half-duplex behavior is push-to-talk radio.

The correct answer is B. Switch port. The Physical Layer of the OSI model is concerned with the physical transmission of signals across network media, including electrical or optical signaling, cabling, connectors, transceivers, and physical interfaces. HPE Aruba Networking hardware and transceiver documentation describes switch ports, transceiver slots, copper cabling, fiber-optic cabling, and link LEDs as physical connection components. A switch port is therefore the only option listed that belongs directly to the Physical Layer. Option A, URL, is associated with application-level access to web resources and is not a Physical Layer item. Option C, IP address, belongs to Layer 3 because it is used for logical addressing and routing. Option D, TCP port, belongs to Layer 4 because TCP ports identify transport-layer application sessions. Although a switch port may participate in Layer 2 switching after a link is established, the physical connector/interface itself is part of the Layer 1 network infrastructure. This makes “switch port” the correct answer from the listed options.

The correct answer is D. Peer device native VLAN ID is 1. The LLDP output shows Neighbor Port VLANID : 1, which identifies the VLAN ID advertised by the neighboring device for that port. HPE Aruba Networking AOS-CX documentation for show lldp neighbor-info explains that LLDP neighbor output displays information about neighboring devices and that the details vary based on the TLVs sent by the neighbor. In the Aruba examples, Neighbor Port VLAN ID and Neighbor Port VLAN Name are shown as LLDP fields, so the VLAN ID value in the output can be validated directly. Option A is not the best answer because although the VLAN name field is blank, the stronger validated configuration item is the VLAN ID value. Option B is incorrect because Neighbor MAU type : 10GIGBASER indicates a 10 Gigabit Ethernet BASE-R PHY type, not a 1 Gigabit transceiver. Option C is incorrect because Port: 1/1/25 is the local switch interface where the neighbor was discovered; the peer device’s port is shown separately as Neighbor Port-ID : 1/1/51. Therefore, the validated statement is that the peer device native VLAN ID is 1.

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. Default VLAN 1 is created by default. HPE Aruba Networking AOS-CX documentation states that all switch ports are part of access VLAN 1 by default. This confirms that VLAN 1 exists in the factory-default configuration and is the default VLAN used by switch ports. Option B is incorrect because AOS-CX VSF documentation states that users cannot disable VSF and that a factory-default switch boots as a VSF-enabled device with member ID 1 on supported VSF platforms. Option A is not the best answer because static routing is not described as the defining factory-default setting in the same way VLAN 1 is. Static routes are administrator-created route entries, but the clearly documented default behavior in the listed choices is that VLAN 1 exists by default. Option D is incorrect because multicast routing is not enabled by default as a general factory-default behavior. Therefore, the statement that correctly describes the factory default is that default VLAN 1 is created and switch ports belong to it by default.

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.
