Question 36

An LTM Specialist has configured a virtual server for www.example.com, load balancing connections to a pool of application servers that provide a shopping cart application. Cookie persistence is enabled on the virtual server. Users are able to connect to the application, but the user's shopping cart fails to update. A traffic capture shows the following:

  • Question 37

    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 { }

    How should the LTM Specialist resolve this issue?
  • Question 38

    -- 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?
