You want to set the default router for your VSYS called corp to be the shared untrust virtual router. How would you do this?

From the corp VSYS as the VSYS admin enter the CLI command set vr untrust-vr default-vrouter From the corp VSYS as the VSYS admin enter the CLI command set VSYS corp vr untrust-vr default-vrouter From the root VSYS as a root level administrator enter the CLI command set VSYS corp vr untrust-vrdefault-vr From the root VSYS as the corp VSYS administrator enter the CLI command set VSYS corp vr untrust-vrdefault-vr

2.

VLAN tagging within a NetScreen device is based on which industry standard?

802.1d 802.1q 802.11q 802.2 802.3

3.

You have created a virtual router called VSYSA-vr and made it sharable. You then create the VSYS using the WebUi, telling it to use an existing VR and selecting the VR called VSYSA-vr. What is the status of the virtual router after you create the VSYS?

The router will be the default router but will no longer be shared. The router will be the default router and will still have a sharable status. The system will not let you use a shared virtual router when you create a new VSYS.The initial virtual router must be private. The system will not create a private vr for the VSYS but will assign the Untrust-vr as the default router. Theshared Virtual router will not be the default router.

4.

What is the valid range of VLAN tag numbers that are usable on a NetScreen device?

0 thru 500 1 thru 500 0thru 2048 1 thru 4094 0 thru 4095

5.

You are logged in as a read-only VSYS administrator and are trying to run snoop from within the virtual system but the command does not appear to be working. Why?

You cannot run snoop from within a VSYS. You must be logged in as a read/write VSYS admin to run snoop in the VSYS. You must be logged in as least a read only root level admin to run snoop in the VSYS. You need to be logged in as at least a read/write root level admin to run snoop in the VSYS.

6.

Which three (3) VSYS features can only be created by the root administrator?

VSYS read/write Admin Policies Sub interfaces Dedicated interfaces Address book entries

7.

You are creating a sub-interface to support VLANs. What must be done to insure the system will insert the VLAN tags?

Turn on VLAN support for the NetScreen device through the admin function. Nothing needs to be done. Create the sub-interface and the system automatically applies the proper tags tothe appropriate frames. Create a cross-reference table entry after you create the sub-interface to map the VLAN tag to the traffic passing through the interface. Sub-interfaces do not support VLAN tags. You need to create logical interfaces off the VLAN1 interface tohave VLANs work on a NetScreen device.

8.

Which two of the following combinations are NOT valid policy options for a system with multiple VSYS?

From within VSYS A: Private VSYS A zone to shared root zone From within VSYS B: private VSYS B zone to private VSYS A zone From within root VSYS: Shared root zone to a Private VSYS A zone From within root VSYS: Shared root VSYS zone to private root VSYS zone

9.

Which item in a virtual system is shared by default?

Trust zone in the Trust-vr Trust zone in the Untrust-vr Untrust zone in the Trust-vr Untrust zone in the Untrust-vr

10.

Which three (3) interface types are supported by Virtual Systems?

Sub interfaces Dedicated interfaces VLAN interfaces Shared interfaces Limited interfaces
