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?


A.

The BIG-IP would drop the request since the traffic didnt 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
leftunchanged.


D.

The source address would not change, but the destination address would be changed to a self-
IP of theBIG-IP.





C.
  

The source address would be changed to the NAT address and destination address would be
leftunchanged.



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 beachieved.


C.

For each virtual server, regardless their default load balancing pools, association with SNAT
pools couldvary 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.





A.
  

A SNAT for all addresses could be defined, and then disable the SNAT processing for select
pools.



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


A.

SNATs are enabled on all VLANs, by default.


B.

SNATs can be configured within a Profile definition.


C.

SNATs can be configured within a Virtual Server definition.


D.

SNAT's are enabled only on the VLAN where origin traffic arrives, by default





A.
  

SNATs are enabled on all VLANs, by default.



C.
  

SNATs can be configured within a Virtual Server definition.



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.

200.200.1.1


B.

150.150.10.11


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





B.
  

150.150.10.11



Which statement is true concerning SNATs using automap?


A.

Only specified self-IP addresses are used as automap addresses.


B.

SNATs using automap will translate all client addresses to an automap address.


C.

A SNAT using automap will preferentially use a floating self-IP over a non-floating self-IP.


D.

A SNAT using automap can be used to translate the source address of all outgoing traffic to the
sameaddress regardless of which VLAN the traffic is sent through.





C.
  

A SNAT using automap will preferentially use a floating self-IP over a non-floating self-IP.



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


A.

NATs support UDP, TCP, and ICMP traffic.


B.

NATs can be configured with mirroring enabled or disabled.


C.

NATs provide a one-to-one mapping between IP addresses.


D.

NATs provide a many-to-one mapping between IP addresses





A.
  

NATs support UDP, TCP, and ICMP traffic.



C.
  

NATs provide a one-to-one mapping between IP addresses.



Which statement describes a typical purpose of iRules?


A.

iRules can be used to add individual control characters to an HTTP data stream.


B.

iRules can be used to update the timers on monitors as a server load changes.


C.

iRules can examine a server response and remove it from a pool if the response is unexpected.


D.

iRules can be used to look at client requests and server responses to choose a pool member to
select forload balancing





A.
  

iRules can be used to add individual control characters to an HTTP data stream.



A virtual server is listening at 10.10.1.100:80 and has the following iRule associated with it: when
HTTP_REQUEST { if { [HTTP::header User-Agent] contains "MSIE" } { pool MSIE_pool } else {
pool Mozilla_pool } If a user connects to http://10.10.1.100.html and their browser does not specify
a User-Agent, which pool will receive the request?


A.

MSIE_pool


B.

Mozilla_pool


C.

None. The request will be dropped


D.

Unknown. The pool cannot be determined from the information provided.





B.
  

Mozilla_pool



Which event is always triggered when the client sends data to a virtual server using TCP?


A.

HTTP_DATA


B.

CLIENT_DATA


C.

HTTP_REQUEST


D.

VS_CONNECTED





B.
  

CLIENT_DATA



A virtual server is listening at 10.10.1.100:any and has the following iRule associated with it: when
CLIENT_ACCEPTED { if {[TCP::local_port] equals 21 } { pool ftp pool } else if {[TCP::local_port]
equals 23 } { pool telnet pool } If a user connects to 10.10.1.100 and port 22, which pool will
receive the request?


A.

ftp pool


B.

telnet pool


C.

None. The request will be dropped.


D.

Unknown. The pool cannot be determined from the information provided.





D.
  

Unknown. The pool cannot be determined from the information provided.
