Question 61

Report Export Collapse

An LTM Specialist has been asked to configure a virtual server to distribute connections between a pool of two application servers with addresses 172.16.20.1 and 172.16.20.2. The application servers are listening on TCP ports 80 and 443. The application administrators have asked that clients be directed to the same node for both HTTP and HTTPS requests within the same session.

Virtual servers vs_http and vs_https have been created, listening on 1.2.3.100:80 and 1.2.3.100:443, respectively.

Which configuration option will result in the desired behavior?

Create pool app_pool with members 172.16.20.1:any and 172.16.20.2:any Assign app_pool as the default pool for both vs_http and vs_https Disable port translation for vs_http and vs_https

An LTM Specialist is investigating reports from users that SSH connections are being terminated unexpectedly. SSH connections are load balanced through a virtual server. The users experiencing this problem are running SQL queries that take upwards of 15 minutes to return with no screen output. The virtual server is standard with a pool associated and no other customizations.

What is causing the SSH connections to terminate?

Users in a branch office are reporting a website is always slow. No other users are experiencing the problem. The LTM Specialist tests the website from the external VLAN along with testing the servers directly. All tests indicate normal behavior.

The LTM Specialist is writing a custom HTTP monitor for a web application and has viewed the content by accessing the site directly via their browser. The monitor continually fails. The monitor configuration is:

ltm monitor http /Common/exampleComMonitor {

defaults-from /Common/http

destination *:*

interval 5

recv 'Recent Searches'

send 'GET /app/feed/current\?uid=20145 HTTP/1.1\\r\\nHost: www.example.com\\r\\nAccept-EncodinG. gzip, deflate\\r\\nConnection: close\\r\\n\\r\\n'

time-until-up 0

timeout 16

}

A trace shows the following request and response:

Accept-Encoding gzip, deflate

Connection: close

Response:
