Ace the F5 301b Exam: Ultimate Preparation Guide

An LTM Specialist needs to rewrite text within an HTML response from a web server. A client is sending the HTTP request below:

GET / HTTP/1.1

Host: www.f5.com

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/20100101 Firefox/16.0

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Accept-LanguagE. en-US,en;q=0.5

Accept-EncodinG. gzip, deflate

Cache-Control: no-cache

Connection: keep-alive

CookiE. somecookie=1

Although a stream profile has been added to the virtual server, the content within the HTTP response is NOT being matched, and therefore NOT modified.

Which HTTP header should the LTM Specialist remove from the request to ensure the content can be matched and modified?

A failover has just occured on BIG-IP1. BIG-IP2 is now active and manages traffic as expected. Both Bigip's are set with a gateway failsafe to check the reachability of the main border router. Switches have performed as expected.

Where should the LTM Specialist check for potential issues?

An LTM Specialist configures an HTTP monitor as follows:

ltm monitor http stats_http_monitor {

defaults-from http

destination *:*

interval 5

recv "Health check: OK"

send "GET /stats/stats.html HTTP/1.1\\r\\nHost: www.example.com\\r\\nAccept-EncodinG. gzip, deflate\\r\\nConnection: close\\r\\n\\r\\n"

time-until-up 0

timeout 16

}

The monitor is marking all nodes as down. A trace of the HTTP conversation shows the following:

GET /stats/stats.html HTTP/1.1

Host: www.example.com

Accept-EncodinG. gzip, deflate

Connection: close

HTTP/1.1 401 Authorization Required

DatE. Tue, 23 Oct 2012 19:38:56 GMT

Server: Apache/2.2.15 (Unix)

WWW-AuthenticatE. Basic realm="Please enter your credentials"

Content-LengtH. 480

Connection: close

Content-TypE. text/html; charset=iso-8859-1

An LTM Specialist is performing an HTTP trace on the client side of the LTM device and notices there are many undesired headers being sent by the server in the response. The LTM Specialist wants to remove all response headers except "Set-Cookie" and "Location."

How should the LTM Specialist modify the HTTP profile to remove undesired headers from the HTTP response?

Which command should the LTM Specialist use to determine the current system time?

An LTM HTTP pool has an associated monitor that sends a string equal to 'GET /test.html'.

Which two configurations could an LTM Specialist implement to allow server administrators to disable their pool member servers without logging into the LTM device? (Choose two.)

Which command should an LTM Specialist use on the command line interface to show the health of RAID array hard drives?

The virtual server is listening on port 443.

A pair of LTM devices are deployed in a high-availability (HA) pair as the diagram shows. After inserting a new rule on the firewalls, the LTM devices become Standby. The rule drops all outbound sessions to the Internet. Only inbound connections are allowed from the Internet. There are no other changes to the environment.

What triggered the LTM device failover?

An LTM device is load balancing SIP traffic. An LTM Specialist notices that sometimes the SIP request is being load balanced to the same server as the initial connection.

Which setting in the UDP profile will make the LTM device more evenly distribute the SIP traffic?
