HTTP profile with X-Forwarded-For

HTTP Transparent profile

SNAT pool using client IP

10. 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 (member)

Least Connections (node)

Predictive (member)

Predictive (node)

11. An organization reports slow performance accessing an Intranet website. All employees use a single proxy IP.

What should the BIG-IP Administrator do?

Change Source Address to proxy IP

Change Load Balancing to Least Connections

Change Fallback Persistence to source_addr

Change Default Persistence to cookie

12. All pool members are online. All other virtual server settings are at default.

What might alter the load balancing behavior? (Choose one answer)

Adding a OneConnect profile

Enabling SNAT automap

Enabling a fallback host in the HTTP profile

Adding a persistence profile

13. The BIG-IP Administrator is investigating whether better TCP performance is possible for a virtual server.

Which built-in profile should be tried first? (Choose one answer)

f5-tcp-legacy

f5-tcp-progressive

f5-tcp-mobile

No option

14. Due to a change in application requirements, a BIG-IP Administrator needs to modify the configuration of a Virtual Server to include a Fallback Persistence Profile.

Which persistence profile type should the BIG-IP Administrator use?

SSL

Hash

Universal

Source Address Affinity

HTTP, HTTPS, FTP, and ICMP with the Availability Requirement of at least one health monitor

HTTPS, HTTP, FTP, and SSH with the Availability Requirement of at least one health monitor

HTTPS, HTTP, FTP, and SSH with the Availability Requirement of all health monitors

18. A Standard Virtual Server is configured with SNAT Automap. Backend servers must see the original client IP.

What should be configured?

Performance (HTTP) VS

Set Protocol to UDP

Set HTTP Profile to None

Set Source Address to 10.1.1.2

Set Destination Address/Mask to 0.0.0.0/0

20. 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? (Choose one answer)

192.168.10.100

192.168.10.200

and target:

192.168.2.150
