F5 Networks BIG IP Local Traffic Manager LTM Specialist Maintain & Troubleshoot 301b LTM Exam Questions

An LTM device is running BIG-IP v10.2.0 software. The LTM Specialist is tasked with upgrading the LTM device to BIG-IP v11.2.0 HF1. The LTM Specialist starts the upgrade process by selecting the uploaded Hotfix and installing to an unused volume. After 10 minutes, the LTM Specialist checks the status of the upgrade process and notices that the process is stalled at 0%.

What should the LTM Specialist verify?

A virtual server for a set of web services is constructed on an LTM device. The LTM Specialist has created an iRule and applied this iRule to the virtual server:

when HTTP_REQUEST {

switch [HTTP::uri] {

"/WS1/ws.jsp" {

log local0. "[HTTP::uri]-Redirected to JSP Pool"

pool JSP

}

default { log local0. "[HTTP::uri]-Redirected to Non-JSP Pool"

pool NonJSP

}

}

}

However, the iRule is NOT behaving as expected. Below is a snapshot of the log:

/WS1/ws.jsp-Redirected to JSP Pool

/WS1/ws.jsp-Redirected to JSP Pool

/WS1/ws.jsp-Redirected to JSP Pool

/WS1/WS.jsp-Redirected to Non-JSP Pool

/ws1/WS.jsp-Redirected to Non-JSP Pool

/WS1/ws.jsp-Redirected to JSP Pool

/ws1/ws.jsp-Redirected to Non-JSP Pool

What is the problem?

An LTM Specialist loads a UCS file generated on a different LTM device and receives the following error message:

"mcpd[2395]: 01070608:0: License is not operational (expired or digital signature does not match contents)"

Which command should the LTM Specialist use to prevent the error?

Given:

Filesystem Size Used Avail Use% Mounted on

/dev/md11 248M 248M 0 100% /

/dev/md13 3.0G 76M 2.8G 3% /config

Which command is used to produce this output?

A web application requires the client to provide the destination server and service identification.

Which HTTP header will supply this information?

-- Exhibit --

-- Exhibit --

Refer to the exhibit.

Which pool can be removed without affecting client traffic?

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

Content-LengtH. 480

Connection: close

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

Which action will resolve the problem?
