質問 1：
A BIG-IP has two SNATs, a pool of DNS servers and a virtual server configured to load-balance UDP traffic to the DNS servers. One SNAT's address is 64.100.130.10; this SNAT is defined for all addresses.
The second SNAT's address is 64.100.130.20; this SNAT is
defined for three specific addresses, 172.16.3.54, 172.16.3.55, and 172.16.3.56. The virtual server's destination is
64.100.130.30:53.
The SNATs and virtual server have default VLAN associations. If a client with IP address 172.16.3.55 initiates a request to the virtual server, what is the source IP address of the packet as it reaches the chosen DNS server?
A. 172.16.3.55
B. 64.100.130.20
C. 64.100.130.10
D. 64.100.130.30
正解：B
質問 2：
Which action CANNOT be performed by an iRule?
A. Substitute a server's response with alternate data.
B. Discard a client before connecting to a server.
C. Chang the virtual server's default pool.
D. Direct a client's request to a pool based on the client's browser's language.
E. Limit a given client to a set amount of bandwidth.
F. Direct a connection request to a specific pool.
正解：C

質問 4：
Why would an administrator capture monitor traffic between a BIG-IP and servers?
A. Viewing monitor traffic could help the administrator to define a more robust monitor.
B. Only client traffic may be captured; monitor traffic may not be captured.
C. If client traffic to servers was failing, viewing and analyzing monitor traffic would determine the reason.
D. If a client were having difficulty logging into a load-balanced SSH server, viewing and analyzing the connection process would determine the reason.
正解：A
質問 5：
