What does the following iRule do?
when CLIENT_ACCEPTED {
if { [matchclass [IP::client_addr] equals WebClient1-Whitelist1] }{
#log local0. "Valid client IP: [IP::client_addr] - forwarding traffic"
#Pool WebClient1
} else {
log local0. "Invalid client IP: [IP::client_addr] - discarding"
discard
}
}

• A.The iRule compares a client IP to a list. If the client IP is NOT on the list, the client is sent to Pool WebClient1. Otherwise, discard and log the discard.
• B.The iRule compares a client IP to a list. If the client IP is on the list, discard and log the discard.
• C.The iRule compares a client IP to a list. If the client IP is on the list, the client is sent to Pool WebClient1.
  Otherwise, discard and log the discard.
• D.The iRule compares a client IP to a list. If the client IP is NOT on the list, discard and log the discard.

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
Which action will resolve the problem?

• A.Add a backslash before the colon in the receive string.
• B.Add a valid username and password to the monitor.
• C.Add an NTLM profile to the virtual server.
• D.Use an HTTPS monitor with a valid certificate instead.

An LTM Specialist has a OneConnect profile and HTTP profile configured on a virtual server to load balance an HTTP application.
The following HTTP headers are seen in a network trace when a client connects to the virtual server:
Clientside:
GET / HTTP/1.1
Host: 192.168.136.100
User-Agent: Mozilla/5.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-EncodinG. gzip, deflate Connection: keep-alive Serverside:
HTTP/1.1 200 OK
DatE. 5 Jun 1989 17:06:55 GMT
Server: Apache/2.2.14 (Ubuntu)
Vary: Accept-Encoding
Content-EncodinG. gzip
Content-LengtH. 3729
X-Cnection: close
Content-TypE. text/html
The LTM Specialist notices the OneConnect feature is working incorrectly.
Why is OneConnect functioning incorrectly?

• A.Server must support HTTP/0.9.
• B.Client must support HTTP keep-alive.
• C.Server must support HTTP keep-alive.
• D.Client must support HTTP/1.0.

-- Exhibit --
Refer to the exhibit.
A client attempts to connect from a Google Chrome browser to a virtual server on a BIG-IP LTM. The virtual server is SSL Offloaded. When the client connects, the client receives an SSL error. The client receives the same errors when trying Mozilla Firefox and Internet Explorer browsers.
The LTM Specialist does an ssldump on the virtual server and receives the results as per the exhibit.
How should this be resolved?

• A.Upgrade the client to support the appropriate SSL cipher suite.
• B.Adjust the SSL key length in the SSL profile to match the minimum required by the client.
• C.Set the virtual server to listen on port 443 (HTTPS).
• D.Select the appropriate "SSL Profile (Client)" in the virtual server settings.
