NEW QUESTION 13
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

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.

What would cause this behavior?
- A. A device group is configured with Auto Failback, and Unit 1 is the default device.
- B. A traffic group is configured with Auto Failback, and Unit 1 is the default device.
- C. Unit 1 is set with the redundancy state preference of active in high availability.

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.
