MAC Caching is a feature that allows a guest user to bypass the captive portal page after the first authentication based on their MAC address 1  MAC Caching can be enabled under the splash page settings in Aruba Cloud Guest 2  MAC Caching can improve the user experience and reduce the network overhead by eliminating the need for repeated authentication.

The Inter-Switch Link (ISL) is a fundamental component of an AOS-CX Virtual Switching Extension (VSX) pair. It serves both as a Layer 2 forwarding path between the VSX peers and as the principal control-path channel used to synchronize operational state between the two switches.

HPE Aruba Networking explicitly identifies the MAC table as one of the data structures synchronized across the VSX ISL. Other synchronized information includes the ARP table, LACP state for VSX LAGs, and MSTP state . This synchronization enables both independent VSX switches to maintain consistent forwarding information and support resilient multi-chassis LAG operation. Aruba Networking

The architecture is important because VSX does not merge both switches into a single control plane. Each peer retains its own control plane, while selected operational databases and protocol states are synchronized through the ISL. HPE ' s Campus Design guidance similarly states that VSX peers synchronize MAC, ARP, STP, and other state tables across the ISL. Aruba Networking

An SVI is configuration rather than the requested synchronized forwarding-table information. UDLD is a link-detection protocol, and RPVST+ is not the answer identified in Aruba ' s ISL synchronization list.

The best option to enhance security for the new IP cameras and scanners in this environment is C. MPSK provides for each device in the WLAN to have its own unique pre-shared key.

MPSK stands for Multi Pre-Shared Key, and it is a feature that allows different devices to connect to the same SSID with different pre-shared keys. This improves the security and scalability of the network, as each device can have its own key and role without requiring 802.1X authentication or an external policy engine. MPSK can be configured either locally on the AP or centrally on Aruba Central 1 2 .

The other options are incorrect because:

A. MPSK Local is a feature that allows the user to configure 24 PSKs per SSID locally on the device. These local PSKs would serve as an extension of the base MPSK functionality. However, MPSK Local is not suitable for this scenario, as it can only support up to 24 devices per SSID, while the client has 250 devices 1 .

B. Aruba ClearPass is a network access control solution that can perform 802.1X authentication and install certificates for devices. However, this option is not feasible for this scenario, as the new IP cameras and scanners do not support 802.1X authentication 3 .

D. MPSK Local will not allow the cameras to share a key and the scanners to share a different key. MPSK Local will assign a different key to each device, regardless of their type. Moreover, MPSK Local can only support up to 24 devices per SSID, while the client has 250 devices 1 .

These are the correct statements regarding the ERSPAN session that needs to be established on an AOS-CX switch for a network administrator to examine the packets over a period of time from their desktop. ERSPAN (Encapsulated Remote Switched Port Analyzer) is a feature that allows an AOS-CX switch to mirror traffic from one or more source ports or VLANs to a remote destination IP address over a GRE (Generic Routing Encapsulation) tunnel. The destination IP address must be the IP address of the administrator’s desktop, which must have a packet capture tool installed to receive and analyze the mirrored traffic. The encapsulation protocol used for ERSPAN is GRE, which adds a header to the mirrored packets with information such as source and destination IP addresses, session ID, etc. The other statements are incorrect because they either do not specify the correct destination IP address or do not use ERSPAN or GRE.

Encryption is a feature supported by SNMPv3 that provides an advantage over SNMPv2c. Encryption protects the confidentiality and integrity of SNMP messages by encrypting them with a secret key. SNMPv2c does not support encryption and relies on community strings for authentication and authorization, which are transmitted in clear text and can be easily intercepted or spoofed. Transport mapping, community strings, and GetBulk are features that are common to both SNMPv2c and SNMPv3.

This is because Best Effort traffic is all other kinds of non-detrimental traffic that are not sensitive to Quality of Service metrics (jitter, packet loss, latency).  A typical example would be peer-to-peer and email applications 2 .  Background traffic is a type of traffic that is used for system maintenance or backup purposes and does not affect the performance or availability of the network 3 .

Therefore, Best Effort traffic has a higher priority than Background traffic in terms of network resources allocation and management.

According to the Aruba Documentation Portal 1 , PAPI (Port Aggregation Protocol) is a protocol that allows multiple physical ports to be aggregated into a single logical port for increased bandwidth and performance. PAPI can be used between AOS-CX switches and gateways, or between AOS-CX switches and other devices.

Option A: Implement an IPSec tunnel to protect PAPI between the AOS-CX switches and the gateway

This is because option A shows how to implement an IPSec tunnel between two devices using the interface command and the ipsec command.  An IPSec tunnel can provide encryption and authentication for PAPI traffic between two devices, such as an AOS-CX switch and a gateway 2 .

Therefore, option A is a feasible option to protect this traffic.
