NEW QUESTION 93
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
}
}
}

/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 should the LTM Specialist do to resolve this?
- A. Use the followinG.switch -lc [HTTP::uri]
- B. Use the followinG.switch [string tolower [HTTP::uri]]
- C. Select the "Process Case-Insensitivity" option for the virtual server.
- D. Set the "Case Sensitivity" option of each member to "None".
Answer: B

An LTM Specialist is troubleshooting an application configured on an LTM device on a one-armed configuration. The application is NOT working through the LTM device but does work when accessed directly via the application servers. The virtual server 192.168.1.211:443 is configured to SNAT using the address 192.168.1.144 and references a pool with the member 192.168.10.80:443. No Client or Server SSL profiles are associated.

What is the problem with the configuration on the LTM device?
- A. Pool member is configured for SSL off-loading.
- B. Virtual server is configured without SSL Profiles.
- C. Pool member is configured to use wrong port.
- D. Virtual server is configured to use wrong port.

An LTM Specialist is troubleshooting an issue with a new virtual server. When connecting through the virtual server, clients receive the message "The connection was reset" in the browser, although connections directly to the pool member show the application is functioning correctly.
ltm pool srv1_https_pool { members { 192.168.2.1:https{ address 192.168.2.1 } } } ltm virtual https_example_vs { destination 192.168.1.155:https ip-protocol tcp mask 255.255.255.255 pool srv1_https_pool profiles { http { } tcp { } } snat automap vlans-disabled }

NEW QUESTION 103
-- Exhibit- -- Exhibit -Refer to the exhibit.
An LTM device is used to load balance web content over a secure channel.
The developers of the web content have done a trace using an HTTP profiler application.
They believe that allowing the LTM device to compress traffic to the client will improve
performance. The client can utilize GZIP or deflate compression algorithms.
An LTM Specialist must implement the compression.
The LTM Specialist has completed the following actions:
1.Create the relevant profile.
2.Apply the relevant profile to the virtual server (VS).
After applying the relevant profile, the LTM device is failing to compress the traffic. Instead,
the traffic is being served with an error.
What is the problem?
- A. The LTM device CANNOT SSL offload the traffic in order to read and compress it.
- B. The Protocol Profile (Server) option of "Allow Compression" needs to be enabled.
- C. The incorrect compression algorithm is applied to the compression profile.
- D. The Protocol Profile (Client) option of "Allow Compression" needs to be enabled.
Answer: A
