ACE can check the health of servers and server farms by configuring health probes (sometimes referred to as keepalives). There are several types of probes. Which three options are valid ACE probes? (Choose three.)
A. TCP
B. ICMP
C. HTTP
D. IPsec
Correct Answer: ABC
Explanation/Reference:
Explanation:
When a server fails in response to the probe, the ACE can check for network problems that prevent a client from accessing that server. The ACE can place the server out of service.
A probe can be any of several types, including HTTP, HTTPS, ICMP, TCP, Telnet, and UDP. You can also configure scripted probes using the TCL scripting language.
