What term is used to describe a NetScreen device sending a request to an OCSP server?

Client Caller Initiator Responder Requesting agent

2.

What three (3) items do you need to download and install on your NetScreen device for IKE gateways to be able to use digital certificates without OCSP?

The CRL list The SCEP list A local Certificate The CA public key certificate The CA private key Certificate

3.

What does an NSRP device send to a network-connected device when a failover occurs and a new master takes over?

Pings Gratuitous ARP Heartbeat Messages Nothing, it uses one MAC for both interfaces so no change is apparent to the connecting device

4.

How would you configure priority for an Active/Active configuration, where you want Device 1 to be master for the first VSD and Device 2 FOR THE SECOND vsd?

Device 1 Device 2
VSD 1: priority 50 VSD 1: Priority 100
VSD 2: priority 50 VSD 2: Priority 100 Device 1 Device 2VSD 1: priority 50 VSD 1: Priority 100
VSD 2: priority 100 VSD 2: Priority 50 Device 1 Device 2VSD 1: priority 100 VSD 1: Priority 50
VSD 2: priority 50 VSD 2: Priority 100 Device 1 Device 2VSD 1: priority 100 VSD 1: Priority 50
VSD 2: priority 100 VSD 2: Priority 50

5.

How many devices can be added to an NSRP cluster configured in Active/Active mode?

1 2 3 4 7

6.

What is the best description of an Active/Active configuration?

Both NetScreen devices are passing traffic. If one device fails, or If a monitored interface fails, all traffic will fail over to the other device. Both Netscreen devices are operational. NSRP provides for a virtual device mac address. If one device orport fails the other device continues the traffic flow immediately. Both NetScreen devices are turned on a but only one carries traffic. The Second device listens to traffic andbuilds all session tables, VPN,SA, and ARP table entries to take over in event of a failure. Both NetScreen devices are passing traffic. If one device fails completely the other one will carry traffic forboth devices. If a monitored interface fails the other device will carry the traffic just for that interface.

7.

You are concerned about the security of HA traffic between NetScreen devices located in different building. What can you do to secure the traffic?

You can encrypt and authenticate the traffic. You can encrypt but not authenticate the traffic. You can authenticate but not encrypt the traffic. You don't need to do anything. All traffic is encrypted and authenticated by default.

8.

As a member of a VSD group, a device may be in which two (2) of the following states?

Init Main Booting Backup Inactive

9.

You want to make sure that the NSRP cluster members keep themselves up to date with session table entries, arp cache entries, DHCP leases etc.. What command do you need to perform to insure this process occurs on a real time basis?

exec rto sync set nsrp rto sync exec nsrp rto sync set nsrp sync global save exec nsrp sycn global-config check-sum

10.

Which three (3) steps comprise the basic NSRP configuration?

Adjust VSD Settings Configure interfaces Establish the HA link Activate NSRP protocol Configure cluster settings
