You meet with a customer to update the network after the prior network manager has left the company for another role.
Which methods can validate the current network state when the available network documentation is invalid?
Choose two.
正解：C、D
解説：
When existing network documentation is unreliable, the architect must reconstruct and validate the current environment using information obtained directly from network devices and physical infrastructure.
Option B uses network discovery protocols, including LLDP, to identify neighboring devices, connected interfaces, and the relationships between infrastructure components.
These observations can be correlated with MAC address tables, routing information, VLAN configurations, and interface status to reconstruct the logical topology.
Option C provides physical verification by inspecting switches, patch panels, transceivers, fiber connections, and copper cabling.
This is particularly important because automated discovery cannot establish every physical connection, especially where unmanaged equipment, intermediate patch panels, or undocumented links exist.
Option A may help recover historical information, but outdated documents cannot independently establish the current network state.
Option D relies on potentially inaccurate information from personnel who may not have operational responsibility for the infrastructure.
Option E is incorrect because an accurate existing-state assessment is essential for requirements analysis, migration planning, risk management, and rollback procedures.
The architect should produce updated physical and logical topology diagrams, document observed discrepancies, and identify dependencies before designing the replacement network.

'Don't Buy at Us' is a US-based retail company that is expanding Into Europe. They are expanding into EMEA with a regional headquarters called HQ2 inside The Netherlands. Their US- based headquarters HQ1 was refreshed last year based on the Aruba ESP architecture. You have treated the design for HQ? based on the same design as HQ1. a two-tier architecture.
The high level is shown below.
Switch BOM for this project based on Two Tier:
Collapsed Core: 2 x Aruba 8360-16Y2C in VSX (ISL 2x100GbE DAC)
Access Stack: 10 x Stack of 6200F 48G Class4 PoE 4SFP+ 740W (each stack has 4 members, VSF with 10GbE VSF links) (2 x 10GbE uplink per stack) During the presentation of your design to the CTO of "Don't Buy at Us" you were informed about the changes they want you to incorporate into the updated design.
1. HQ2 will include the EMEA regional distribution center (EMEA-OISTR)
next to the HQ2.
2. Only two pairs of OS1 are available between HQ2 and EMEA-DlSTR.
3. The uplinks from all access stacks need to increase to 2 x 25GbE, the fiber in HQ2 and EMEA-DI5TRI is certified for 25GbE.
4. EMEA-DlSTR needs at least 7 x stack of Aruba 48 ports switches (each stack has 4 members).
Which answer based on best practice is presenting the correct Switch BOM tor the updated design?
正解：A
解説：
Based on the requirements provided by "Don't Buy at Us," the updated design needs to accommodate 25GbE uplinks and a minimum of 7 stacks of 48-port Aruba switches for the EMEA-DISTR. Option C is the most suitable based on best practices, as it proposes:
A core configuration consisting of two Aruba 8360-12C in VSX for the collapsed core with ISL of
2x100GbE DAC, which will provide robust core networking with high-speed interconnects, suitable for the demands of a regional distribution center and headquarters. Aggregation with two stacks, each with 2 Aruba 8360-12C in VSX (ISL 2x100GbE DAC), accommodating the uplink capacity requirements.
Access stacks with a total of 17 stacks of Aruba 6300F 48-port 1GbE Class 4 PoE with 4-port SFP56 (each stack has 4 members, VSF with 50GbE VSF links, 2 x 25GbE uplinks per stack), which exceeds the minimum requirement of 7 stacks and provides the necessary uplink bandwidth. This configuration supports the 25GbE uplink speeds, satisfies the required number of switch stacks for the EMEA distribution center, and is compatible with the existing 25GbE- certified fiber infrastructure at HQ2 and EMEA-DISTR.

A large multinational financial institution has engaged you to design a new full-stack wired and wireless network for its new 6-story regional office building. The facility's bottom two floors will be retail space for a large banking branch. The upper floors will be carpeted corporate office space, with each floor approximately
100,000 sq ft (9290 sq m). Data centers are all offsite and are outside this project's scope. The customer is underserved by its current L2-based network infrastructure and wants to use modern best practices in the new design. The network must be fully resilient and fault-tolerant, with dynamic segmentation at the edge.
The retail space will provide public guest Wi-Fi access. Retail associates will use corporate tablets for customer service, and the retail floors will contain a mixture of wired and wireless devices. Corporate users will primarily connect wirelessly, although several wired clients, printers, and hard VoIP phones will be used.
The customer also plans to renovate the corporate office space to take advantage of 'smart office' technology.
These upgrades will enable blue-dot wayfinding, presence analytics, and other location-based services.
After further discussions with the customer, the team determined that EVPN-VXLAN will provide dynamic segmentation. The customer wants to ensure that a particular VNI is present only when it is used on that switch.
Which solution is valid and meets this technical requirement?
正解：C
解説：
EVPN-VXLAN provides scalable network segmentation by separating the routed IP underlay from the logical overlay used to transport endpoint traffic.
Option A uses CX 6300 VSF stacks as access-layer VXLAN Tunnel Endpoints (VTEPs), with a redundant CX 8325 VSX distribution pair.
The CX 6300 supports EVPN-VXLAN functionality, allowing endpoint traffic to be encapsulated at the access layer rather than relying entirely on centralized overlay termination.
Through the EVPN control plane, VTEPs exchange endpoint reachability information and participate in VXLAN forwarding relationships for the relevant network identifiers.
HPE's EVPN-VXLAN documentation states that VXLAN data-plane tunnels form between VTEPs interested in the same VXLAN Network Identifier.
This supports the customer's objective of avoiding unnecessary VXLAN forwarding relationships for network segments that are not relevant to a particular VTEP.
Option B places VTEP functionality on the CX 8320 distribution switches instead of the CX 6300 access stacks, reducing the distributed edge functionality required by the design.
Option C is invalid because the CX 6100 does not provide the required EVPN-VXLAN VTEP capabilities, and the proposed CX 6300 VSX configuration is unsupported.
Option D incorrectly describes a four-member virtual chassis of CX 8325 switches.
The selected architecture should also validate route-reflector connectivity, overlay VLAN/VNI mappings, and supported software versions.

It has been identified that the client's existing network must retransmit packets because of possible hardware or configuration issues. Hardware configuration and transport reliability will need to be reviewed before completing the new design.
How should this phenomenon be classified?
Original exhibit - Question 47
正解：A
解説：
Packet loss occurs when data packets transmitted across a network fail to reach their intended destination.
The scenario identifies repeated packet retransmissions caused by potential hardware or configuration problems. This behavior is consistent with packet loss affecting transport reliability.
For connection-oriented protocols such as TCP, missing data can be detected through acknowledgment behavior, retransmission timers, and duplicate acknowledgments.
When the sender determines that a packet has not been successfully delivered, it may retransmit the affected information.
Packet loss can result from interface errors, damaged cabling, defective transceivers, congestion, buffer exhaustion, excessive queue drops, or incorrect network configurations.
Option A, jitter, describes variation in the delay experienced by packets. Jitter can negatively affect real-time applications but is not synonymous with missing packets.
Option C, latency, represents transmission delay between endpoints. High latency can affect retransmission timers, but it does not inherently establish packet loss.
To diagnose the stated problem, the architect should inspect interface error counters, dropped packets, CRC errors, optical signal levels, congestion statistics, and end-to-end transport performance.
HPE Aruba Networking AOS-CX supports interface monitoring and diagnostic capabilities that can help identify abnormal packet drops and hardware-related transmission errors.

A global furniture retail company called 'No-Stair Inc.' requests you design their new WLAN infrastructure for a global footprint. Each location of No-Stair Inc.' has a similar layout: three small manager offices, a warehouse, and a 'retail' area. The 'retail' area and the warehouse together amount to 95% of the location. The IT department of the company Is minimally engaged In their LAN refresh so the CTO of the company has shared the information below Current WLAN Infrastructure Is based on the 802.11n "WlFI4Less" access-points series (both model 2013-INT (2.4 only Internal antenna) and model 2019-EXT (dual-band external antenna only)). These AP models are standalone without any centralized management. Last year 'No- Stair InC ran a project called secure. It' ensuring that all needed network security was Implemented to be fully compliant with their security standards. During this project, they also upgraded the AAA infrastructure to handle the Increased AAA requests. No additional Wi-Fi or security requirements are listed for this WLAN refresh, which means that 'No-Stair Inc.' will continue to use bridged SSIDs. with local breakout into different VLANs.
The CTO of No-Stair Inc.' understands the need for you to ask additional questions to deliver the design. The questions may be sent in written form and will be answered within two weeks. What additional question needs to be answered in order to collect needed information for tie WLAN design?
正解：C
解説：
When upgrading a WLAN infrastructure, it's important to ensure that the existing wired network can support the new wireless access points (APs) in terms of connectivity and power (if using Power over Ethernet, PoE). For 'No-Stair Inc.,' which is planning a WLAN refresh without specific changes to the Wi-Fi or security requirements but potentially with new AP models and configurations, verifying the capacity of the wired network is crucial. The question about whether the existing wired network has enough drops (ethernet connections) for the upgraded Wi-Fi network addresses this concern. It's essential to ensure that there are sufficient ethernet ports available in the right locations to connect the new APs, and that these ports can provide the necessary power and data rates required by modern APs. This information will help in planning the deployment of the new APs, avoiding potential bottlenecks and ensuring that the upgraded WLAN can deliver the desired performance and coverage
