A Virtual Server uses an iRule to send traffic to pool members depending on the URI. The BIG-IP Administrator needs to modify the pool member in the iRule.Which event declaration does the BIG-IP Administrator need to change to accomplish this?
Answer(s): C
URI-based traffic steering requires inspection of the HTTP request. BIG-IP processes HTTP headers and URIs in the HTTP_REQUEST event. Pool member selection based on URI must occur before the request is sent to the server, making HTTP_REQUEST the correct event.
A BIG-IP Administrator creates a new Virtual Server to load balance SSH traffic. Users are unable to log on to the servers.What should the BIG-IP Administrator do to resolve the issue?
Answer(s): B
SSH is a TCP Layer 4 protocol. Applying an HTTP profile causes BIG-IP to expect HTTP headers, breaking SSH sessions. Removing the HTTP profile allows raw TCP forwarding.
A BIG-IP Administrator uses backend servers to host multiple services per server. There are multiple virtual servers and pools defined, referencing the same backend servers.Which load balancing algorithm is most appropriate to have an equal number of connections on each backend server?
Least Connections (node) balances connections across the physical server regardless of how many services or pool members exist on that node.
What is the status of a pool member when manual resume is enabled and a health check first fails and then passes?
Answer(s): A
With manual resume enabled, BIG-IP does not automatically return a pool member to service after recovery. The member remains offline until manually re-enabled.
Some users who connect to a busy Virtual Server have connections reset by the BIG-IP system. Pool member resources are NOT a factor.What is a possible cause?
When the connection limit is reached, BIG-IP resets new connections, even if pool members are healthy.
