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 BIG-IP, what changes, if any, would take place when the BIG-IP processes such packets?

  1. The BIG-IP would drop the request since the traffic didn arrive destined to the NAT address.The BIG-IP would drop the request since the traffic didn? arrive destined to the NAT address.
  2. The source address would not change, but the destination address would be changed to the NAT address.
  3. The source address would be changed to the NAT address and destination address would be left unchanged.
  4. The source address would not change, but the destination address would be changed to a self-IP of the BIG-IP.

Answer(s): C



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?

  1. A SNAT for all addresses could be defined, and then disable the SNAT processing for select pools.
  2. The decision to perform source address translation is always based on VLAN. Thus, the goal cannot be achieved.
  3. For each virtual server, regardless their default load balancing pools, association with SNAT pools could vary dependent upon need.
  4. The decision to perform source address translation is always based on a client's address (or network). Thus, this goal cannot be achieved.

Answer(s): A



Which two statements are true about SNATs? (Choose two.)

  1. SNATs are enabled on all VLANs, by default.
  2. SNATs can be configured within a Profile definition.
  3. SNATs can be configured within a Virtual Server definition.
  4. SNAT's are enabled only on the VLAN where origin traffic arrives, by default

Answer(s): A,C



A BIG-IP has two load balancing virtual servers at 150.150.10.10:80 and 150.150.10.10:443. The port 80 virtual server has SNAT automap configured. There is also a SNAT configured at 150.150.10.11 set for a source address range of 200.200.1.0 / 255.255.255.0. All other settings are at their default states. If a client with the IP address 200.200.1.1 sends a request to https://150.150.10.10, what is the source IP address when the associated packet is sent to the pool member?

  1. 200.200.1.1
  2. 150.150.10.11
  3. Floating self IP address on VLAN where the packet leaves the system
  4. Floating self IP address on VLAN where the packet arrives on the system

Answer(s): B
