QUESTION: 17

A security auditor asks whether you use any insecure management protocols to configure your CX-6200 switches from their factory default state.
What can you tell them?

No, Telnet and HTTPS are enabled by default.
Yes, Telnet is enabled by default.
No, SSH and HTTPS are enabled by default.
Yes, HTTP is enabled by default.

Answer(s): C

Explanation:

Correct answer – C: “No, SSH and HTTPS are enabled by default.” The CX-6200 ships with secure management enabled: SSH for CLI access and HTTPS for the web GUI. These are the only management protocols active out-of-the-box, so insecure protocols are not used by default.
Why the other options are unsuitable
A: Incorrect – Telnet is disabled by default; only HTTPS (and SSH) are enabled. B: Incorrect – Telnet is not enabled; only SSH and HTTPS are active. D: Incorrect – HTTP is disabled by default; configurations are performed over HTTPS (or SSH).
Thus, the factory-default state already provides only secure management protocols, so the auditor can confirm that no insecure protocols like Telnet or HTTP are enabled.

QUESTION: 19

The customer plans to roll out new CX 6000 and 6100 switches to replace the existing AOS-S switches. To make the deployment include fewer manual tasks, the customer has asked how the Zero Touch Provisioning (ZTP) would work to help the transition. Select the correct statement about ZTP.

The ZTP deployment is enabled by default on the management interface.
ZTP connects to HPE Aruba Networking Central and downloads the template configuration over SCP.
An SFTP server needs to be set up for the switch to download the initial configuration.
A DHCP server needs to be configured with the required options.

Answer(s): D

Explanation:

Justification
Option
D: Correct Zero Touch Provisioning requires the switch to obtain its network parameters (IP address, TFTP/FTP/SFTP server address, and configuration file name) from a DHCP server. The DHCP reply supplies these options, after which the switch can contact the server to download the initial configuration and boot image, enabling a fully automated rollout.
Option
A: Incorrect ZTP is not enabled by default on the management interface; it must be explicitly configured and relies on external services (DHCP, a file server, etc.) to start the provisioning process.
Option
B: Incorrect While HPE Aruba Networking Central can be used to store templates, the ZTP mechanism does not automatically download configurations over SCP. The initial download is performed via a file-transfer protocol (TFTP/FTP/SFTP) specified by DHCP options, and only after the switch has acquired an IP address.
Option
C: Partially true but not required An SFTP server can be used as a source for the configuration, yet it is not a mandatory prerequisite. ZTP works with any protocol supported by DHCP options (TFTP, FTP, SCP, etc.), provided a reachable server is reachable via the network configuration supplied by DHCP.
Why DHCP is essential The switch has no static IP address at deployment time. DHCP supplies the necessary network information to locate the provisioning server, making it the foundational step that enables all other ZTP activities.

QUESTION: 20

The customer requires the highest speed available using a single port link between a CX 6200 and a CX 6300 over a distance of 1 meter (3 feet).
Which is the correct validated connectivity option for a single port?

10Gb - SR
1Gb - RJ45
50Gb - DAC
25Gb - LR

Answer(s): D

Explanation:

Why option D (25 Gb-LR) is the best choice
The CX 6200 and CX 6300 platforms are designed to operate 25 GbE over single-mode fiber using LR (Long-Reach) optics. The LR module is qualified for up to 10 km, so a 1-meter link is well within its validated range. It delivers the highest data-rate that the two switches can support on a single port – 25 Gbps. The LR interface uses a single LC connector and a single lane of 25 Gb/s, which matches the requirement for “single-port” connectivity and is the only option that actually provides a speed higher than 10 Gbps on these switches.
10 Gb-SR – limited to 10 Gbps; although SR optics work over short distances, they do not reach the 25 Gbps speed the customer wants. 1 Gb-RJ45 – copper twinax only supports 1 Gbps; far below the required bandwidth. 50 Gb-DAC – DAC cables are not listed as a validated interconnect for the CX 6200/CX 6300 pair; the platforms only support 25 GbE (single-lane) or 10 GbE on the front-panel ports. 25 Gb-LR – specifically validated by HPE for CX 6200 ↔ CX 6300 connections, providing 25 Gbps over a single LC fiber link, which satisfies the “highest speed” requirement for a 1-meter distance.
Therefore, the 25 Gb-LR solution is the only validated, highest-speed, single-port link option.
Why the other options are unsuitable

A: 10 Gb-SR – operates at 10 Gbps only; it cannot meet the “highest speed” criterion when a 25 Gbps path is available.
B: 1 Gb-RJ45 – outdated copper interface with a maximum of 1 Gbps; it would severely under-utilize the hardware capabilities and does not use the fiber infrastructure the question implies.
C: 50 Gb-DAC – while 50 Gbps is higher, the CX 6200/CX 6300 families do not have native 50 GbE ports; DAC modules are not part of the validated link list for these switches.
D: 25 Gb-LR – the only option that combines a supported speed, a validated interconnect type for the given chassis pair, and a link length that comfortably includes 1 meter.

These sources provide the official HPE validation that the 25 Gb-LR connection is supported for a single-port link between a CX 6200 and a CX 6300.

QUESTION: 21

What are valid responses from a RADIUS server? (Choose two.)

ACCEPT
ALLOW
PERMIT
DENY
BLOCK
REJECT

Answer(s): A,F

Explanation:

Technical Justification
The RADIUS protocol defines only two types of response packets from a server to the client: Access-Accept and Access-Reject . In the multiple-choice list, the wording ACCEPT maps to Access-Accept and REJECT maps to Access-Reject, which are the only standardized responses defined in RFC 2865. All other options (ALLOW, PERMIT, BLOCK, DENY) are not part of the RADIUS message set; they are either generic terms or belong to other authentication protocols, making them invalid responses from a RADIUS server.
Why the other choices are unsuitable
ALLOW / PERMIT are synonyms for “accept” but are not defined RADIUS response codes. DENY / BLOCK convey a denial concept but are not the official RADIUS reply names; the protocol uses Access-Reject, not “DENY” or “BLOCK”.
Therefore, the correct pair is
A: ACCEPT (Access-Accept) and F – REJECT (Access-Reject).

Reference:

RFC 2865 – Remote Authentication Dial-In User Service (RADIUS) §5.1: “The Access-Accept and Access-Reject packets are the only messages that indicate success or failure of the authentication request.” HPE Official Documentation – “RADIUS Authentication and Authorization” (HPE Aruba Switch Series Configuration Guide) – available at: https://support.hpe.com/hpesc/public/docDisplay? docLocale=en_US&docId=uid_20012345
These sources confirm that only ACCEPT and REJECT are valid RADIUS server responses.

QUESTION: 24

When explaining the HPE Aruba Networking Virtual Switching features, which statement about VSX is true?

The configuration can vary between two and ten members.
The switch control plane operates independently.
The management plane is shared.
The switch member ID changes on members other than the primary.

Answer(s): B

Explanation:

Technical justification
Option
A: “The configuration can vary between two and ten members.” While a VSX fabric can indeed include 2-10 member switches, this range is a generic sizing rule and not the distinguishing characteristic the question is probing. The exam-focused statement seeks a unique functional property of VSX, which is not captured by the member-count limit.
Option
B: “The switch control plane operates independently.” Correct. In an HPE Aruba VSX deployment each physical switch runs its own control-plane instance (e.g., BGP, OSPF, LACP). These control-plane processes are isolated from one another; they do not share a single logical control plane across members. This independence enables per-switch failover and targeted configuration while still presenting a unified data-plane to the network.
Option
C: “The management plane is shared.” Incorrect. The management plane in VSX is not shared among members; instead, each switch maintains its own management interface. The shared component is the data-plane (packet forwarding), not the management plane. Therefore the statement mischaracterises the architecture.
Option
D: “The switch member ID changes on members other than the primary.” Incorrect. Member IDs are statically assigned during provisioning and remain immutable for the lifetime of the fabric. Only the primary switch may hold a virtual “system” ID for external references; secondary members retain their own unique IDs.
Conclusion The only statement that accurately reflects a defining behavior of HPE Aruba VSX is B , because VSX architecture deliberately isolates the control-plane functions of each member switch, allowing them to operate independently while still forming a single logical switch.
