The correct answer is A. 10G-DAC. The limiting device in this connection is the CX 6200. HPE Aruba Networking CX 6200 models use built-in high-speed uplinks, and the CX 6200 product listings identify models with 4SFP+ uplinks. SFP+ uplinks support 10G, not 25G, 50G, or 100G single-port connectivity. HPE Aruba Networking transceiver guidance also notes that CX 6200 switches support split-side SFP connections only in available 10G-capable SFP ports, and that 50G transceivers can only be used in ports capable of 50G speeds, such as SFP56-capable ports. Therefore, even though the CX 8100 supports higher-speed connectivity options, the shared validated single-port option between the two switch families is 10G over DAC for a short 3-meter connection. Option B is incorrect because the CX 6200 does not have 100G ports. Option C is incorrect because 25G-LR is not the best validated 3-meter option and exceeds the CX 6200 SFP+ port capability. Option D is incorrect because 50G-DAC requires 50G-capable ports.

The correct answer is C. Application Layer. HTTP, or Hypertext Transfer Protocol, is identified in HPE Aruba Networking documentation as an application protocol used to transfer data over the web. The same HPE Aruba Central documentation explains that HTTP defines how messages are formatted and transmitted and how web servers and browsers respond to commands. This places HTTP at the application layer because it directly supports user-facing web communication rather than packet forwarding, addressing, framing, or physical transmission. HPE Aruba documentation also describes Deep Packet Inspection and AppRF as Layer 7 or Application Layer features that classify applications and web traffic, further supporting that HTTP is treated as application-layer traffic. Option A is incorrect because the Session Layer manages sessions between systems, but HTTP itself is not categorized there in this context. Option B is incorrect because the Network Layer handles IP addressing and routing. Option D is incorrect because the Data Link Layer handles local network framing, MAC addressing, and switching behavior.

The correct answer is B. Transport Layer. Data segmentation is a Transport Layer function. At Layer 4, protocols such as TCP divide application data into smaller pieces called segments so that data can be transported between endpoints. The Transport Layer also uses TCP and UDP port numbers to identify application conversations between hosts. HPE Aruba Networking AOS-CX ACL documentation references TCP/UDP ports as Layer 4 ports, which aligns transport-layer port usage with the Transport Layer. The Application Layer provides user-facing application services, but it does not perform transport segmentation. The Network Layer handles logical IP addressing and routing. The Data Link Layer handles Ethernet framing, MAC addressing, and local delivery on a network segment. Therefore, when the question asks where data segmentation occurs in the OSI model, the correct answer is the Transport Layer. ( arubanetworking.hpe.com )

The correct answer is A. The VSF feature is enabled by default. The key difference is between the older AOS-Switch VSF behavior used by the 2930F and the AOS-CX VSF behavior used by the CX 6200. In AOS-Switch 2930F manual VSF configuration, each switch must be configured individually for VSF before joining the stack. In contrast, HPE Aruba Networking AOS-CX VSF documentation for CX switches states that users cannot disable VSF and that a factory-default switch boots as a VSF-enabled device with member ID 1. Therefore, when replacing 2930F switches with CX 6200 switches, the important stacking difference is that VSF is inherently enabled on the CX 6200 platform. Option B is incorrect because VSF MAD is not automatically enabled on each LAG simply because LACP active mode is configured. Option C is incorrect because it states the opposite of the CX 6200 behavior. Option D is not the key difference for CX 6200; it more closely resembles manual AOS-Switch VSF setup behavior where switches are individually prepared for VSF participation.

The correct answer is B. Light. Multi-mode cable refers to multi-mode fiber-optic cabling. In fiber-optic transmission, data is carried using light through the fiber core. HPE Aruba Networking’s transceiver documentation explains that multimode fibers have thicker fiber cores and can transport light in multiple modes. The same HPE Aruba Networking transceiver guidance discusses optical transceivers transmitting light pulses and managing light loss across fiber-optic cabling. Therefore, in the context of multi-mode fiber, the signal being modulated to represent data is light. Option A is incorrect because radio is used in wireless transmission, not fiber-optic cabling. Option C is incorrect because voltage is associated with electrical copper cabling, such as twisted-pair Ethernet, rather than optical fiber. Option D is incorrect because pressure is not used as the signaling method for standard Ethernet fiber links. This question is focused on Layer 1 media behavior, and multi-mode fiber is a Physical Layer medium that transports optical signals between network transceivers.

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 answers are B and E. On HPE Aruba Networking AOS-CX switches, configuration changes are made to the running configuration. To ensure those changes persist after a reboot, the running configuration must be saved to the startup configuration. HPE Aruba Networking documentation states that write memory saves the running configuration to the startup configuration and is an alias of copy running-config startup-config. The copy running-config startup-config command copies the current running configuration into the startup configuration, overwriting the existing startup configuration if one is already present. Option A, commit confirm, is not the AOS-CX command used to save the current running configuration for reboot persistence. Option C, save force, is not the correct AOS-CX command for this task. Option D is the reverse operation; copy startup-config running-config would copy the saved startup configuration into the active running configuration rather than saving current changes for the next reboot. Therefore, the two valid commands are write memory and copy running-config startup-config.

The correct answer is C. The contents of Flash survive when a device reboots or powers down. In HPE Aruba switch operation, the active configuration used by the device while it is running is the running configuration. The startup configuration is the saved configuration that is preserved and used after reboot. HPE Aruba documentation explains that saving the running configuration writes it to the startup configuration file in Flash memory, allowing the configuration to remain after the switch reboots. This confirms that Flash is nonvolatile storage. HPE Aruba AOS-CX documentation also describes eMMC or SSD switch storage as nonvolatile memory used for persistent storage of configurations, files, databases, and scripts. Option A is incorrect because switch Flash storage is not normally expanded by adding extra Flash for configuration storage. Option B is incorrect because the running configuration is held as the active operating configuration, not simply “Flash.” Option D is incorrect because show running-config displays the current running configuration, not the saved startup configuration stored in Flash.

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.
