The reason is that the linkup delay timer is a feature that delays bringing downstream VSX links up, following a VSX device reboot or an ISL flap. The linkup delay timer has two phases: initial synchronization phase and link-up delay phase.

The initial synchronization phase is the download phase where the rebooted node learns all the LACP+MAC+ARP+STP database entries from its VSX peer through ISLP. The initial synchronization timer, which is not configurable, is the required time to download the database information from the peer.

The link-up delay phase is the duration for installing the downloaded entries to the ASIC, establishing router adjacencies with core nodes and learning upstream routes. The link-up delay timer default value is 180 seconds. Depending on the network size, ARP/routing tables size, you might be required to set the timer to a higher value (maximum 600 seconds).

When both VSX devices reboot, the link-up delay timer is not used.

Therefore, by configuring the linkup delay timer to include LAGs 101 and 102, which are part of the same VSX device as LAG 201, you can ensure that both devices have enough time to synchronize their databases and form routing adjacencies before bringing down their downstream links.

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.

According to the Aruba Documentation Portal1, user-based tunneling (UBT) is a feature that uses GRE to tunnel ingress traffic on a switch interface to a gateway for further processing. UBT enables a switch to provide a centralized security policy, using per-user authentication and access control to ensure consistent access and permissions.

Option A: The switch will put the client on the access VLAN

This is because option A shows how UBT works on an Aruba switch. When a device connects to the network, it is authenticated using either MAC Authentication or 802.1X and triggers an enforcement policy from ClearPass, which contains an enforcement profile with a user role configuration. The user role can be assigned locally on the switch or on ClearPass as part of an enforcement profile. The user role determines the VLAN that the device belongs to and the access policies that apply to it23.

Therefore, option A is correct.
