السؤال #2
Assume a BIG-IP has no NATs or SNATs configured. Which two scenarios are possible when client traffic arrives on a BIG-IP that is NOT destined to a self-IP? (Choose two.)
A. If the destination of the traffic does not match a virtual server, the traffic will be discarded
B. If the destination of the traffic does not match a virtual server, the traffic will be forwarded based on routing tables
C. If the destination of the traffic matches a virtual server, the traffic will be processed per the virtual server definition
D. If the destination of the traffic matches a virtual server, the traffic will be forwarded, but it cannot be load-balanced since no SNAT has been configured

السؤال #4
Which statement accurately describes the difference between two load-balancing modes specified as "member" and "node"?
A. There is no difference; the two terms are referenced for backward compatibility purposes
B. When the load-balancing choice references "node", priority group activation is unavailable
C. Load-balancing options referencing "nodes" are available only when the pool members are defined for the "any" port
D. When the load-balancing choice references "node", the addresses' parameters are used to make the load-balancing choice rather than the member's parameters

السؤال #7
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?
A. 200
B. 150
C. Floating self IP address on VLAN where the packet leaves the system
D. Floating self IP address on VLAN where the packet arrives on the system

السؤال #8
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
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)
