QUESTION 1 Assume a client's traffic is being processed only by a NAT; no SNAT or virtual server processing takes place. Also assume that the NAT definition specifies a NAT address and an origin address while all other settings are left at their defaults. If the origin server were to initiate traffic via the BIGIP, what changes, if any, would take place when the BIG-IP processes such packets. A. The BIG-IP would drop the request since the traffic didn arrive destined to the NAT address. B. The source address would not change, but the destination address would be changed to the NAT address. C. The source address would be changed to the NAT address and destination address would be left unchanged. D. The source address would not change, but the destination address would be changed to a self-IP of the BIG-IP. Answer: C

QUESTION 2 A site wishes to perform source address translation on packets arriving from the Internet for clients using some pools but not others. The determination is not based on the client's IP address, but on the pool they are load balanced to. What could best accomplish this goal. A. A SNAT for all addresses could be defined, and then disable the SNAT processing for select pools. B. The decision to perform source address translation is always based on VLAN. Thus, the goal cannot be achieved. C. For each virtual server, regardless their default load balancing pools, association with SNAT pools could vary dependent upon need. D. The decision to perform source address translation is always based on a client's address (or network). Thus, this goal cannot be achieved. Answer: A

to define an address that grants administrative access to either system at any time to define an address that allows either system to initiate communication at any time to define an address that allows network devices to route traffic via a single IP address to define an address that gives network devices greater flexibility in choosing a path to forward traffic

When network failover is enabled, which of the following is true. A. B. C. D.

The failover cable status is ignored. Failover is determined by the network status only. Either a network failure or loss of voltage across the failover cable will cause a failover. A network failure will not cause a failover as long as there is a voltage across the failover cable. The presence or absence of voltage over the failover cable takes precedence over network failover.

Answer: C

Specify the desired MAC address for each self-IP address for which you want this feature enabled. C. Specify the desired MAC address for each VLAN on the active system and synchronize the systems. D. Specify the desired MAC address for each floating self-IP address for which you want this feature enabled. Answer: A

QUESTION 64 Which action will take place when a failover trigger is detected by the active system. A. B. C. D.

The active device will take the action specified for the failure. The standby device also detects the failure and assumes the active role. The active device will wait for all connections to terminate and then failover. The standby device will begin processing virtual servers that have failed, but the active device will continue servicing the functional virtual servers.

Answer: A

QUESTION 65 Assuming that systems are synchronized, which action could take place if the failover cable is connected correctly and working properly, but the systems cannot communicate over the network due to external network problems. A. B. C. D.

If network failover is enabled, the standby system will assume the active mode. Whether or not network failover is enabled, the standby system will stay in standby mode. Whether or not network failover is enabled, the standby system will assume the active mode. If network failover is enabled, the standby system will go into active mode but only until the network recovers.
