The correct answer is D. By default, all VLAN traffic is tagged to traverse a trunk link except the native VLAN. In HPE Aruba Networking AOS-CX, a trunk interface can carry traffic for multiple VLANs, and VLAN tagging is used to identify traffic from different VLANs across the trunk. However, the native VLAN is the exception. HPE Aruba Networking documentation explains that the native VLAN is the VLAN to which incoming untagged traffic is assigned, and by default VLAN 1 is assigned as the native VLAN for trunk interfaces. This means normal trunk behavior is that VLAN traffic is tagged, while native VLAN traffic can be untagged unless configured otherwise. Option A is incomplete because it ignores native VLAN behavior. Option B is incorrect because the native VLAN concept applies to trunk interfaces generally, not only when a port is part of a LAG. Option C is incorrect because VLAN trunking applies to Layer 2 interfaces, not routed ports. Therefore, the default trunk behavior is tagged VLAN traffic except for the native VLAN.

The correct answer is B. RESTful API is a secure way to monitor CX switches. HPE Aruba Networking AOS-CX supports a REST API as a management and automation interface. The REST API is accessed through HTTPS, which provides encrypted communication for management operations. This makes it a secure monitoring and automation option for a customer using an open-source network management platform that can integrate through APIs. Option A is incorrect because RMON is a monitoring feature, but it is not the best answer for secure modern monitoring access. Option C is not the best answer because using a dedicated out-of-band management port improves management-plane isolation, but it is not itself a monitoring protocol or method. Option D is incorrect because SNMPv2 is not considered secure; HPE Aruba hardening guidance recommends SNMPv3 instead of older SNMP versions because older versions lack authentication and encryption protections. Therefore, from the listed options, RESTful API is the best secure monitoring method for CX switches. ( arubanetworking.hpe.com )

The correct answer is C. In-band management uses the production switching network rather than the dedicated out-of-band management port. For an HPE Aruba Networking CX 4100i switch, HPE Aruba Networking AOS-CX documentation states that configuring the in-band management interface begins by entering interface vlan 1. The guide then shows that the in-band management interface can be configured with DHCP or with a static IP address. Therefore, assigning ip address 10.10.10.10/24 under interface vlan 1 is the correct in-band management configuration from the choices. Option A is incorrect because interface mgmt is the out-of-band management interface, not in-band management. Option D is also out-of-band for the same reason. Option B is not the best answer because routing is not required under the VLAN interface for this in-band management IP configuration. The essential configuration is the VLAN interface with the static IP address

The correct answer is B. LLDP. Link Layer Discovery Protocol, or LLDP, is the most useful feature for building a physical connectivity diagram because it helps identify directly connected neighboring devices and their interface relationships. HPE Aruba Networking Central documentation notes that LLDP is enabled by default on switches and is used to display AOS-CX switches in topology views. Aruba Central’s topology feature provides a graphical representation of the site, including the network layout and device details. This makes LLDP directly relevant to discovering and documenting physical network connections. Option A, MSTP, is a spanning tree protocol used to prevent Layer 2 loops and manage redundant paths, not to document physical connectivity. Option C, ZTP, is used for automated device provisioning, not topology discovery. Option D, L2TP, is a tunneling protocol and is unrelated to creating physical connectivity diagrams. Therefore, LLDP is the best answer because it provides neighbor discovery information that can be used to map how network devices are physically connected.

The correct answer is A. SNMP v3. HPE Aruba Networking AOS-CX hardening documentation recommends using SNMPv3 instead of older SNMP versions. Older SNMP versions are unauthenticated and unencrypted, and the community string is transmitted in plaintext. SNMPv3 supports users, authentication, and strong encryption, including stronger authentication and privacy protocols. This makes SNMPv3 the correct version when the requirement is to monitor switches with encrypted SNMP data. Option B and option C are incorrect because SNMPv2 and SNMPv2c do not provide the same authentication and encryption protections required by the question. Option D is incorrect because SNMPv4 is not a valid SNMP version used for this purpose on HPE Aruba Networking CX switches. Therefore, the secure SNMP monitoring choice is SNMPv3.

The correct answer is D. The VSF stack remains fully operational. The output shows the VSF topology is a ring. In a ring topology, each member has an alternate VSF path through another member. If only the VSF link between members 1 and 2 is disconnected, members 1 and 2 can still communicate through member 3: member 1 connects to member 3, and member 3 connects to member 2. This changes the physical topology from a ring to a chain, but it does not split the stack. HPE Aruba Networking VSF documentation states that a ring topology provides resiliency against link and member hardware failures because any single failure does not isolate the remaining stack members from each other, and Aruba strongly recommends ring topology where possible. Options A, B, and C are incorrect because a single link failure in this three-member ring does not isolate the conductor, standby, or member. Split detection using the management interface would become relevant only if the stack actually split into separate fragments.

The correct answer is A. The VSF ports automatically forward the traffic for configured VLANs. In HPE Aruba Networking CX VSF, the VSF link ports are dedicated stack-fabric interfaces between VSF members. They are not configured like normal access or trunk ports for user VLAN forwarding. HPE Aruba Networking Central documentation for AOS-CX ports and LAGs notes that VLAN mode options such as access or trunk are not visible for VSF ports, which confirms that VSF ports are not manually configured as normal VLAN trunks. Once the VSF stack is formed, the stack operates as one logical switch, and the VSF links carry the necessary internal stack traffic automatically, including traffic associated with configured VLANs. Option B is incorrect because you do not configure VSF ports as trunk ports with vlan trunk allowed all. Option C is incorrect because vsf-sync is not required for VLAN forwarding across VSF links. Option D is incorrect because VLAN 4095 is not manually configured on VSF links for this purpose.

The correct answer is A. CX 6400. The requirement calls for a chassis-based core switch that can scale to a 12U chassis and support 100G speeds toward the aggregation layer. HPE Aruba Networking CX 6400 QuickSpecs identify the CX 6400 as a modular switch family and include the larger CX 6410 chassis option, which is a 10-slot chassis platform. HPE also lists CX 6400 40/100GbE QSFP28 line modules, which provide the required 100G connectivity. This makes CX 6400 the correct fit for a chassis solution that can scale to the requested physical size and provide 100G uplinks. The CX 10000, CX 9300, and CX 8325 are fixed-form-factor platforms, not modular chassis solutions, so they do not match the stated chassis requirement. Therefore, the best initial proposal is the HPE Aruba Networking CX 6400.

The correct answer is C. Commands - show interface error-statistics. Because the users and the document management server are in the same subnet, traffic is switched locally rather than routed across multiple Layer 3 hops. If packet loss is suspected during file uploads, the most useful verification is to inspect interface error counters on the switch ports involved. HPE Aruba Networking AOS-CX documentation includes the show interface < IFNAME > error-statistics command, which displays interface error statistics such as receive and transmit errors, CRC/FCS errors, drops, runts, giants, and related counters. HPE Aruba Networking Central documentation states that the Commands tab can run troubleshooting commands on managed devices and show the output in the Device Output section. A cable test may help detect physical cabling faults, but it does not directly confirm packet loss counters. Traceroute is less useful within the same subnet. Ping can show reachability loss, but interface error statistics provide better evidence of switch-port packet errors causing performance problems.

The correct matches are based on the high-availability technologies supported by each CX switch family in the answer list. HPE Aruba Networking AOS-CX VSF documentation states that VSF supports up to 8-member stacks for CX 6200F devices and up to 10-member stacks for CX 6300 devices. That makes CX 6200 match “VSF - 8 members” and CX 6300 match “VSF - 10 members.” HPE Aruba Networking documentation for VSX support lists the CX 8100 as a VSX-supported switch series, so CX 8100 matches “VSX.” The CX 6100 and CX 4100i do not match the listed VSF 8-member, VSF 10-member, or VSX choices. Although AOS-CX VSF documentation lists other VSF limits for some platforms, the choices provided only include VSF-8, VSF-10, VSX, and None; therefore, CX 6100 and CX 4100i map to “None” in this drag-and-drop question.
