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



Which statement is true concerning SNATs using automap?

  1. Only specified self‐IP addresses are used as automap addresses.
  2. SNATs using automap will translate all client addresses to an automap address.
  3. A SNAT using automap will preferentially use a floating self‐IP over a non‐floating self‐IP.
  4. A SNAT using automap can be used to translate the source address of all outgoing traffic to the same address regardless of which VLAN the traffic is sent through.

Answer(s): C



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

  1. NATs support UDP, TCP, and ICMP traffic.
  2. NATs can be configured with mirroring enabled or disabled.
  3. NATs provide a one‐to‐one mapping between IP addresses.
  4. NATs provide a many‐to‐one mapping between IP addresses.

Answer(s): A,C

  1. iRules can be used to add individual control characters to an HTTP data stream.
  2. iRules can be used to update the timers on monitors as a server load changes.iRules can be used to update the timers on monitors as a server. load changes.
  3. iRules can examine a server response and remove it from a pool if the response is unexpectediRules can examine a server. response and remove it from a pool if the response is unexpected
  4. iRules can be used to look at client requests and server responses to choose a pool member to select for load balancing
