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 B. You need to specify the mgmt VRF at the end of the ping command. On HPE Aruba Networking CX switches, the out-of-band management interface uses the management VRF. If you issue a normal ping 10.1.50.11 command without specifying the management VRF, the switch attempts to send the ping using the default routing context rather than the out-of-band management interface. HPE Aruba Networking AOS-CX documentation for the ping command shows that the command supports the optional vrf < vrfname > parameter. The AOS-CX diagnostics documentation also specifically lists this as a cause of ping failure: the user intended to ping through the management VRF but forgot to add vrf mgmt to the command. The correct command would therefore be similar to ping 10.1.50.11 vrf mgmt. Option A is incorrect because the management interface can reach routed destinations if the management VRF has the proper route. Option C is incorrect because the management VRF already exists. Option D is incorrect because ping is supported.

Built-in stateful firewall = D

400Gb port speeds = C

7–12U chassis form factor = A

8U chassis form factor = B

The correct matches are CX 10000 for built-in stateful firewall, CX 9300 for 400Gb port speeds, CX 6400 for the 7–12U chassis form factor, and CX 8400 for the 8U chassis form factor. HPE Aruba Networking documentation describes the CX 10000 Distributed Services Switch as including stateful firewall capabilities through its distributed services architecture, making it the correct match for built-in stateful firewall. The CX 9300 is identified by HPE Aruba Networking as a high-density 100G/400G switch platform, so it matches the 400Gb port-speed feature. The CX 6400 is a modular chassis family available in 5-slot and 10-slot models; HPE QuickSpecs describe these as compact 7 RU and 12 RU chassis models, matching the 7–12U chassis form factor. The CX 8400 is a modular campus core and aggregation switch described by HPE as a compact 8-slot, 8U chassis, which matches the 8U chassis form factor. These four features are product-line differentiators and should not be interchanged.

The correct answer is D. A DHCP server must be configured with the required options. HPE Aruba Networking AOS-CX documentation explains that ZTP is used to automatically load a switch configuration from a server when the switch boots from a factory-default configuration. The AOS-CX Fundamentals Guide for the 4100i, 6000, and 6100 switch series states that ZTP supports DHCP standards and DHCP options, and that support is limited to the listed DHCP options for ZTP on AOS-CX. The same guide describes setting up ZTP on a trusted network by preparing the configuration, setting up a TFTP server, and configuring DHCP-related information. Option B is incorrect because the guide references TFTP, not SFTP, for the ZTP server workflow. Option C is incorrect because the listed process does not use SCP for the initial template download. Option A is misleading because ZTP is enabled only when the switch is in factory-default configuration; the key requirement is the DHCP-based provisioning environment with the proper options.

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 A. Change the hash algorithm. In a LAG, traffic is not normally split packet-by-packet across every member link. Instead, the switch uses a hashing method to choose which physical interface in the aggregate should transmit each flow. The output shows that the current hash is l3-src-dst, which means the load-balancing calculation uses Layer 3 source and destination IP information. If many flows share the same source and destination IP pair, traffic can be unevenly distributed, causing one link to become congested while another link is lightly used. HPE Aruba Networking AOS-CX documentation states that the lacp hash command controls the selection of an interface in an aggregate group and supports Layer 2, Layer 3, and Layer 4 source/destination hash options. Changing the hash algorithm, for example to include Layer 4 source and destination TCP/UDP ports, can improve distribution when Layer 3 values alone are not diverse enough. Changing LACP mode, configuring static LAG, or changing LACP heartbeat rate would not directly fix uneven traffic distribution.

The correct answer is C. Automates root cause analytics. HPE Aruba Networking AOS-CX documentation describes the Network Analytics Engine, or NAE, as a framework within AOS-CX switches that automates the detection of issues and automates root cause analysis. NAE agents monitor switch resources, events, configuration, protocol states, and other operational data to help identify issues faster. This helps administrators move from manual troubleshooting to analytics-driven troubleshooting directly on the switch. Option A is not the best answer because NAE is not simply a feature that automatically creates tech-support diagnostic files. Option B is incorrect because automated configuration backups are not the main purpose of NAE. Option D is incorrect because NAE does not primarily create support events in the HPE Aruba Networking Support Portal. Its purpose is local switch analytics, issue detection, and root cause analysis. Therefore, the best description is that NAE automates root cause analytics.

The correct answer is A. operators. HPE Aruba Networking AOS-CX documentation for the CX 8400 identifies built-in user groups that exist by default on the switch. These include administrators, operators, and auditors. The operators group has limited privileges, such as basic display-only CLI access and the ability to view nonsensitive switch configuration information. It does not have full switch configuration privileges. The other options—helpdesk, servicedesk, and support—are not listed as built-in default user groups for the CX 8400. Those names could be created manually as custom local user groups in some environments, but they are not default AOS-CX groups. Therefore, from the available choices, the default group is operators.

The correct answer is D. QoS. Poor call quality during network congestion is commonly caused by delay, jitter, or packet loss affecting real-time voice and video traffic. HPE Aruba Networking AOS-CX Quality of Service documentation explains that QoS allows administrators to customize how different traffic types are serviced based on their characteristics and importance. QoS helps keep important traffic moving at an acceptable speed regardless of current bandwidth usage. HPE Aruba documentation also states that VoIP traffic is delay and jitter sensitive and should receive priority service for optimum transmission. Microsoft Teams voice and video traffic is latency-sensitive, so configuring QoS is the correct approach to prioritize this traffic when the network is busy. Option A, CoS, is a specific Layer 2 priority marking method that can be part of a QoS design, but the broader feature to configure is QoS. Option B, ZIP, is not relevant. Option C, IGMP, is used for multicast group management and does not solve general Teams call-quality issues.

The correct answer is D. 6. In a switched Ethernet network, each individual switch link or switch port represents a separate collision domain. The diagram shows four end-user device links: PC-A to the VLAN 10 access switch, PC-B to the VLAN 10 access switch, PC-C to the VLAN 20 access switch, and PC-D to the VLAN 20 access switch. It also shows two uplinks from the access switches to the Layer 3 switch or routing switch that contains the SVIs for VLAN 10 and VLAN 20. That gives a total of six physical Ethernet links, and therefore six collision domains. The VLANs do not reduce this count to two; VLANs define Layer 2 broadcast domains, not collision domains. The SVIs also do not create one collision domain; they are Layer 3 gateway interfaces used for routing between VLANs. HPE Aruba Networking campus design documentation describes Layer 2 and Layer 3 switching technologies used in campus topologies, while HPE Aruba switch documentation treats physical switch ports as individual Ethernet interfaces. For this diagram, the collision-domain count is based on the physical switched links, so the answer is 6.
