A company runs a legacy application that does not support cookies and does not use SSL. Clients connect from a NAT device, so many users share the same public IP address. The application requires that a user's session be maintained on the same server. Which persistence profile would be the most appropriate?

Universal persistence with an iRule that uses a custom header value as the persistence key.

An administrator is planning to change the persistence profile on a virtual server from source address to cookie persistence. The change must be implemented with minimal disruption to existing sessions. The administrator has created a new cookie persistence profile. What is the best way to apply the change?

Delete the source address profile first, then assign the cookie profile.

Assign the new cookie persistence profile to the virtual server, replacing the source address profile.

Change the source address profile's type to cookie.

Apply the cookie profile to the pool instead of the virtual server.

An administrator is configuring a new virtual server for a web application that requires session stickiness. The application uses a custom header 'X-User-ID' to identify users. The administrator wants to use universal persistence to maintain stickiness based on this header. What must the administrator do to configure this?

Create an SSL session ID persistence profile and set the session ID to the header value.

Create a source address persistence profile and set the source address to the header value.

Create a universal persistence profile and write an iRule that uses the 'persist' command with the header value.

Create a cookie persistence profile and set the cookie name to 'X-User-ID'.

An administrator needs to change the persistence profile on a production virtual server from source address to cookie persistence to better handle users who share the same public IP address. The change must be applied without disrupting existing sessions. What is the correct approach?

Create a new cookie persistence profile and assign it to the virtual server, replacing the source address profile.

Edit the existing persistence profile and change its type from source address to cookie.

Delete the source address persistence profile and then create a cookie persistence profile with the same name.

Modify the virtual server's load balancing method to use cookies.

A company runs an e-commerce application on a pair of BIG-IP load-balanced web servers. The application stores the user's shopping cart in memory on the web server that handled the initial request. Users frequently abandon carts when they are redirected to a different server during a session. The application does not use cookies and the client IP addresses are stable for the duration of a user's session. Which persistence profile should the administrator apply to the virtual server to maintain session stickiness?
