NEW QUESTION # 48
What is the best practice for using VSX at the core of a 3-tier design?
Answer: D
Explanation:
In a 3-tier network design consisting of core, aggregation, and access layers, the implementation of Virtual Switching Extension (VSX) at the core is considered a best practice when the aggregation layer functions primarily at Layer 3 with routing protocols like OSPF facilitating traffic forwarding between the core and aggregation layers. This design choice, as verified by Aruba Campus Access documents, leverages the high availability and redundancy features of VSX technology while maintaining efficient and scalable routing at the aggregation layer. Implementing VSX at the core in such a scenario ensures seamless failover and redundancy, minimizing the risk of downtime and ensuring consistent performance across the network. The core layer, equipped with VSX, provides a robust and resilient backbone for the network, facilitating efficient traffic management and routing decisions, which is critical for large-scale enterprise networks.
NEW QUESTION # 49
The clients existing network is experiencing trouble with voice occasionally dropping out on phone calls between office locations, it Is determined that no packet loss is occurring and QOS is likely the cause.
With what phenomenon Is the client currently experiencing issues?
Answer: A
Explanation:
The client is experiencing issues with Jitter, as depicted in Option B. Jitter refers to the variation in time between packets arriving, caused by network congestion, timing drift, or route changes. In voice communications, jitter can manifest as the occasional dropping out of voice on phone calls because the variable delay can affect the steady stream of voice packets needed for a clear conversation. Even when there is no packet loss, high levels of jitter can significantly impact the quality of Voice over IP (VoIP) calls. Quality of Service (QoS) settings are essential in managing jitter, as they can prioritize voice traffic over other types of data, ensuring that voice packets are delivered consistently and in the correct order to minimize delays and prevent call quality degradation. Aruba Campus Access solutions would typically include QoS features to manage and mitigate jitter on the network.
NEW QUESTION # 50
'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 2ยป ICOG0E DAC)
Access Slack: 10 x Slack of Aruba 6200F 48G Class4 PoE 4SFP- 740W each stack has A members. VSF with 10GbE VSF links) 12 x 10GbE uplink pet 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 0S1 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).
Whichanswer based on best practice is presenting the correct Switch BOM tor the updated design?
Answer: D
Explanation:
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.
NEW QUESTION # 51
Which alternative source is best suited for site surveys or simul-ations if no floor plans are available?
Answer: D
Explanation:
When floor plans are not available for site surveys or simulations, the best alternative source to use is the fire escape plan (Option D). Fire escape plans are typically available in most buildings and provide a simplified layout of the premises, including walls, doors, and sometimes the location of permanent fixtures. While not as detailed as architectural floor plans, fire escape plans can offer enough information for initial site survey estimations and RF planning. They allow network designers to understand the basic layout and potential RF obstacles or coverage areas, making them a practical tool for preliminary wireless network planning and simulations in the absence of more detailed floor plans.
NEW QUESTION # 52
Which is true when it comes to Aruba Central licensing for gateways? (Select two.)
Answer: A,D
Explanation:
In the context of Aruba Central licensing for gateways, it is true that SD-WAN Gateway functionality requires a specific security licensing (Option B), which is essential for enabling advanced security features and capabilities in an SD-WAN deployment. This includes functionalities like firewall, threat management, and secure VPN connections. Additionally, Aruba SD-Branch Gateway licenses allow for the use of standard WLAN Gateway features within a campus environment (Option C). This means that with an SD-Branch Gateway license, the gateway can handle traditional WLAN management and security tasks, in addition to its SD-WAN capabilities, providing a unified solution for both branch and campus deployments.
