-- Exhibit -- -- Exhibit -- Refer to the exhibit. An LTM Specialist is troubleshooting an HTTP monitor that is marking a pool member as down. Connecting to the pool member directly through a browser shows the application is up and functioning correctly. How should the send string be modified to correct this issue?
-- Exhibit -- -- Exhibit -- Refer to the exhibit. An LTM Specialist is troubleshooting a new HTTP monitor on a pool. The pool member is functioning correctly when accessed directly through a browser, although the monitor is marking the member as down. As part of the troubleshooting, the LTM Specialist has captured the monitor traffic via tcpdump. How should the LTM Specialist resolve this issue?
-- Exhibit -- -- 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?
-- 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?
