Which IP address will the client address be changed to when SNAT automap is specified within a Virtual Server configuration?

  1. The floating self IP address on the VLAN where the packetleaves the system.
  2. The floating self IP address on the VLAN where the packet arrives on the system.
  3. It will alternate between the floating and nonfloating self IP address on the VLAN where the packet leaves the system so that port exhaustion is avoided.
  4. It will alternate between the floating and nonfloating self IP address on the VLAN where the packet arrives on the system so that port exhaustion is avoided.

Answer(s): A



A BIG-IP has a virtual server at 150.150.10.10:80 with SNAT automap configured. This BIGIP also has a SNAT 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 the virtual server, 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): C



Which VLANs must be enabled for a SNAT to perform as desired (translating only desired packets)?

  1. The SNAT must be enabled for all VLANs.
  2. The SNAT must be enabled for the VLANs where desired packets leave the BIG-IP.
  3. The SNAT must be enabled for the VLANs where desired packets arrive on the BIG-IP.
  4. The SNAT must be enabled for the VLANs where desired packets arrive and leave the BIG-IP.

Answer(s): C



A standard virtual server is defined with a pool and a SNAT using automap. All other settings for the virtual server are at defaults. When client traffic is processed by the BIG-IP, what will occur to the IP addresses?

  1. Traffic initiated by the pool members will have the source address translated to a self-IP address but the destination address will not be changed.
  2. Traffic initiated to the virtual server will have the destination address translated to a pool member address and the source address. Traffic initiated to the virtual server will have the destination address translated to a pool member. address and the source address translated to a self-IP address.
  3. Traffic initiated by selected clients, based on their IP address, will have the source address translated to a self-IP address but the destination will only be translated if the traffic is destined to the virtual server.
  4. Traffic initiated to the virtual server will have the destination address translated to a pool member address and the source address. Traffic initiated to the virtual server will have the destination address translated to a pool member. address and the source address translated to a self-IP address. Traffic arriving destined to other destinations will have the source translated to a self-IP address only.

Answer(s): B



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 a client were to initiate traffic to the NAT address, what changes, if any, would take place when the BIG-IP processes such packets?

  1. The source address would not change, but the destination address would be translated to the origin address.
  2. The destination address would not change, but the source address would be translated to
    theorigin address.
  3. The source address would not change, but the destination address would be translated to the NAT's address.
  4. The destination address would not change, but the source address would be translated to the NAT's address.
