Which statements regarding 0SPFv2 route redistribution are true for Aruba OS CX switches? (Select two.)

Correct Answer:AE
These are two correct statements regarding OSPFv2 route redistribution for Aruba OS CX switches. Route redistribution is a process that allows routes from one routing protocol or source to be injected into another routing protocol or destination. OSPFv2 is a link-state routing protocol that supports route redistribution from various sources, such as connected, static, BGP, etc. The ??redistribute connected?? command will redistribute all connected routes for the switch, including local loopback addresses, into OSPFv2. The ??redistribute static route-map connected-routes?? command will redistribute all static routes that have a matching permit statement in the route map named ??connected- routes?? into OSPFv2. The other statements are incorrect because they either do not reflect the correct behavior of route redistribution commands or do not exist as valid commands.

A customer is using stacked Aruba CX 6200 and CX 6300 switches for access and a VSX pair of Aruba CX 8325 as a collapsed core 802 1X is implemented for authentication. Due to the lack of cabling, some unmanaged switches are still in use Sometimes devices behind these switches cause network outages The switch should send a warning to the helpdesk when the problem occurs You have been asked to implement an effective solution to the problem
What is the solution for this?

Correct Answer:C
This is the correct solution to the problem of devices behind unmanaged switches causing network outages due to loops. Loop protection is a feature that allows an Aruba CX switch to detect and prevent loops by sending loop protection packets on each port, LAG, or VLAN on which loop protection is enabled. If a loop protection packet is received by the same switch that sent it, it indicates a loop exists and an action is taken based on the configuration. Loop protection should be configured on all edge ports of the Aruba CX 6200 and CX 6300 switches, which are the ports that connect to end devices or unmanaged switches. The trap-option should be set up to send a warning to the helpdesk when a loop is detected. The other options are incorrect because they either do not configure loop protection or do not set up the trap-option.

With the Aruba CX 6000 24G switch with uplinks of 1/1/25 and what does the switch do when a client port detects a loop and the do-not-disabie parameter is used?

Correct Answer:B
The correct answer is B. An event log message is created.
The do-not-disable parameter is used to prevent the switch from disabling the port when a loop is detected by the loop-protect feature. Instead, the switch will generate an event log message that indicates the port number and the VLAN ID where the loop was detected. The switch will also send a trap to the SNMP manager, if configured1.
The other options are incorrect because:
✑ A. Port status will not be validated once status is cleared. The port will remain enabled even if a loop is detected, unless the loop-protect action is changed to tx- disable or tx-rx-disable1.
✑ C. The network analytics engine will not be triggered by a loop detection. The network analytics engine is a feature that allows users to monitor and troubleshoot network issues using scripts and agents2.
✑ D. Port status LED will not blink in amber with 100Hz. The port status LED will indicate the normal port status, such as link speed and activity, regardless of the loop detection3.

Which feature supported by SNMPv3 provides an advantage over SNMPv2c?

Correct Answer:D
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.

How is Dynamic Multicast Optimization (DMO) implemented in an HPE Aruba wireless network?

Correct Answer:A
The correct answer is A. DMO is configured individually for each SSID in use in the network.
DMO is a feature that allows the AP to convert multicast streams into unicast streams over the wireless link. This enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. DMO is configured individually for each SSID in use in the network, as different SSIDs may have different multicast requirements.
According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure DMO is:
✑ Dynamic multicast optimization: Select Enabled to allow IAP to convert multicast streams into unicast streams over the wireless link. Enabling Dynamic Multicast Optimization (DMO) enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients.
The other options are incorrect because:
✑ B. The AP does not use QoS to provide equal air time for multicast traffic. QoS is a feature that prioritizes different types of traffic based on their importance and latency sensitivity. QoS does not affect how multicast streams are transmitted over the wireless link.
✑ C. DMO is not configured globally for each SSID in use in the network. DMO is configured individually for each SSID, as different SSIDs may have different multicast requirements.
✑ D. The controller does not convert multicast streams into unicast streams. The AP does the conversion, as it is closer to the wireless clients and can optimize the transmission based on the client capabilities and channel conditions.
