Question 145

-- 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?

The incorrect compression algorithm is applied to the compression profile.

The LTM device CANNOT SSL offload the traffic in order to read and compress it.

The Protocol Profile (Client) option of "Allow Compression" needs to be enabled.

The Protocol Profile (Server) option of "Allow Compression" needs to be enabled.

Correct Answer: B

The compression of traffic by an LTM (Local Traffic Manager) device requires the ability to inspect and manipulate the content of the traffic. However, in this scenario, SSL (Secure Sockets Layer) traffic is being load balanced, as indicated by the port number 443, which is used for HTTPS. To compress the traffic, the device must be able to decrypt it first. Since the LTM device is not set up to perform SSL offloading (decrypting the secure traffic), it cannot read the traffic to apply compression algorithms. Therefore, the appropriate step is to configure SSL offloading on the LTM device.
