301b Exam Question 131

Internet clients connecting to a virtual server to download a file are experiencing about 150 ms of latency and no packet loss.
Which built-in client-side TCP profile provides the highest throughput?
  • 301b Exam Question 132

    The LTM device is configured to provide load balancing to a set of web servers that implement access control lists (ACL) based on the source IP address of the client. The ACL is at the network level and the web server is configured to send a TCP reset back to the client if it is NOT permitted to connect.
    The virtual server is configured with the default OneConnect profile.
    The ACL is defined on the web server as:
    Permit: 192.168.136.0/24 Deny: 192.168.116.0/24
    The packet capture is taken of two individual client flows to a virtual server with IP address
    192.168.136.100.
