An LTM device supports two power supplies. The value of the BigDB key "platform.powersupplymonitor" is equal to enable.
Where would the error message be visible if one of the power supplies fails or is NOT plugged in?
A. visible only via the console
B. in the /var/log/ltm log file
C. in the /var/log/kern.log file
D. in the /var/log/tmm log file
An LTM Specialist is troubleshooting a problem on an eCommerce website. The user browses the online store using port 80, adding items to the shopping cart. The user then clicks the "Checkout" button on the site, which redirects the user to port 443 for the checkout process. Suddenly, the user's shopping cart is shown as empty. The shopping cart data is stored in memory on the server, and the default source address persistence profile is used on both virtual servers.
How should the LTM Specialist resolve this issue?
A. Add an HTTP profile to both virtual servers.
B. Enable SNAT Automap on both virtual servers.
C. Create a custom persistence profile and enable "Map Proxies."
D. Create a custom persistence profile and enable "Match Across Services."

What is the issue?
A. The port 80 pool member is deleting the user's session cookie.
B. The port 443 pool member is deleting the user's session cookie.
C. The port 80 and port 443 connections are balanced to the same node.
D. The port 80 and port 443 connections are balanced to different nodes.
An LTM Specialist is troubleshooting an issue with a new virtual server. When connecting through the virtual server, clients receive the message "Unable to connect" in the browser, although connections directly to the pool member show the
application is functioning correctly.
The LTM configuration is:
ltm virtual /Common/vs_https {
destination /Common/10.10.1.110:443
ip-protocol udp
mask 255.255.255.255
pool /Common/pool_https

vlans-disabled
}
ltm pool /Common/pool_https {
members {
/Common/172.16.20.1:443 {
address 172.16.20.1
}
}
}
How should the LTM Specialist resolve this issue?
A. Remove an HTTP monitor from the pool.
B. Add an HTTP profile to the virtual server.
C. Enable the pool member on the correct VLAN.
D. Select the correct protocol for the virtual server.

How should the LTM Specialist resolve this issue?
A. Add '200 OK' to the monitor's receive string.
B. Add 'Connection: close\r\n' to the monitor's send string.
C. Change the interval on the monitor from 5 seconds to 30 seconds.

There are three servers in the pool: 172.16.20.1, 172.16.20.2, and 172.16.20.3, with the virtual IP address 10.0.20.88.
A user CANNOT connect to an HTTP application. To understand the problem and find a solution, the LTM Specialist runs two concurrent traces on the LTM device, with the following results:

D. Configure the virtual server to use SNAT.
An LTM Specialist configured a virtual server to load balance a custom application. The application works when it is tested from within the firewall but it fails when tested externally. The pool member address is 192.168.200.10:80. A capture from an external client shows:
GET /index.jsp HTTP/1.1 Host: 207.206.201.100 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Connection: keep-alive HTTP/1.1 302 Found DatE.

What is the solution to this issue?
A. Assign a SNAT pool to the virtual server.
B. Add a Web Acceleration Profile to the virtual server.
C. Configure redirect rewrite option in the HTTP profile.
D. Configure a content filter on the backend web server.
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. Connection
B. Accept
C. Cache-Control
D. Accept-Encoding
