The correct answer is C. Create a new SVI and use attach command.
To create a new SVI for a separate routing table, you need to use the attach command to associate the SVI with a VRF (Virtual Routing and Forwarding) instance. A VRF is a logical entity that allows multiple routing tables to coexist on the same switch. Each VRF has its own set of interfaces, routing protocols, and routes that are isolated from other VRFs.
According to the AOS-CX Virtual Switching Framework (VSF) Guide1, one of the steps to configure VRF-aware VSF is:
Configure the VRFs on each member switch and assign the SVIs to the respective VRFs using the attach command. For example:
switch(config)# vrf red
switch(config-vrf)# exit
switch(config)# interface vlan 10
switch(config-if-vlan)# ip address 10.1.1.1/24
switch(config-if-vlan)# attach vrf red
The above commands create a VRF named red and assign VLAN 10 SVI to it. The SVI has an IP address of 10.1.1.1/24.
The other options are incorrect because:
A) You cannot attach a VRF to a VLAN directly. You need to create an SVI for the VLAN and then attach the VRF to the SVI.
B) You cannot create a new routing table manually. You need to create a VRF and then use routing protocols or static routes to populate the routing table for the VRF.
D) You cannot attach a routing table to a VLAN directly. You need to create an SVI for the VLAN and then attach a VRF that has a routing table associated with it.

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.

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.

The system-mac command is used to configure a fixed MAC address for the VSX system. This MAC address is used as the source MAC address for all routed traffic from the VSX node. The system-mac command is highly recommended for preventing traffic disruptions when the primary VSX switch restores after the secondary VSX switch, such as during a primary switch hardware replacement or a power outage. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID. The system-mac command can be used to change this default MAC address if needed.
