Question 1

You are delivering a replacement collapsed core network proposal to the customer where the core switches will have the switched virtual interlaces (SVl) configured. The customer is not sure that a USX pair of switches will Be able to act as I tie spanning tree root in their environment.

Which options are true about spanning tiee and VSX that will help assure the customer that a VSX pair of switches are appropriate for a collapsed core? (Select two.)

AThe primary vsx switch ts the spanning tree root and the default behavior is the links on the secondary vsx switch are blocked with sub-millisecond failover assured by vsx active-gateway.

BWhen LAG interfaces are configured on a VSX pair of switches, both switches are 'operational primary' and ensure active-active LAG operation equally.

CBoth VSX switches are configured with the system MAC and then create unique STP bridge-IDs to identify 'operational primary' and 'operational secondary' for proper STP functioning

DAruba VSX switches support either multiple spanning tree (MSTP) or rapid per VLAN spanning tree (RPVST).

EThe ISL between VSX switches is never part of STP domain and doesn't send or receive BPDUs on this link and this ensures the 'operational primary' and 'operational secondary' switches are deterministic to other dual-attached switches.

Answer : D, E

According to Aruba Campus Access documents and learning resources, Aruba VSX (Virtual Switching Extension) technology is designed to provide advanced high availability and redundancy features for campus networks. Specifically, answer D is correct because Aruba VSX supports both Multiple Spanning Tree Protocol (MSTP) and Rapid Per VLAN Spanning Tree (RPVST), ensuring efficient tree structures for VLANs and rapid convergence in case of topology changes. Answer E is also true as the Inter-Switch Link (ISL) used for the VSX pair is not part of the Spanning Tree Protocol (STP) domain, meaning it does not send or receive Bridge Protocol Data Units (BPDUs). This design prevents the ISL from influencing STP calculations, ensuring that the operational roles of the primary and secondary switches in the VSX pair are clear and predictable to the rest of the network. This separation helps maintain deterministic behavior and failover capabilities in the network, aligning with the goals of a collapsed core network design.

Question 5

A global cruise line company needs to refresh its current fleet. They win refresh the insides' of the ship to be cost-effective and increase their sustain ability. They Mill replace the complete WLAN/LAN hardware of the ship. In this refresh, the company will not refresh Us current security requirements. The CIO also wants to limit the number of unused ports in the switches. Future expansion will always mean a refresh of hardware. They start with the smallest ship with a maximum of 800 guests

Each ship has a LAN infrastructure consisting of two core switches, up to 10 redundant distribution switches, and up to 500 access switches (400 cabins. 100 technical rooms). The Core switches are located in the MDF of the ship and the distribution switches are located in the IDFs of the ship. Each cabin and technical room gets one single access switch.

The cabling structure of the ship will not be refreshed. Each IDF is connected to the MDF by SMF. of which two pairs are available for the interconnect between the core and distribution. The length of SM fiber between MDF and IDF is less than 300 meters (930 ft) and the type used is 0S1. Each cabin is connected by a single 0M2 pair to the IDF. the maximum length is 60 meters (200 ft). Each technical room is connected by a single 0M2 pail to the IDF. with lengths between 100 and 150 meters (320 and 500 ft).

For each cabin/technical room the customer is looking to replace their current fan-less 2530/2540 without changing the requirements, except they need to upgrade the uplink to distribution switch to 10GbEto handle the increased network traffic, and the technical rooms need redundant power.

The WLAN infrastructure will be 1:1 refreshed without new cabling or new AP locations. Their WLAN Infrastructure is based on the 200/300 series Indoor and outdoor APs running instantOS (less than 300 APs). the customer has no change in WLAN requirements.

The cruise line company will replace its current Internet connection before the LAN/WLAN refresh. The new Internet connection will provide a 99.8% uptime, which is needed to ensure the paid guest Wi-Fi is always operational. With this new internet connection, the CIO of the cruise line wants to base the design on the ESP architecture from Aruba because Internet connection is guaranteed.
