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?
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 environment is a single HTTP virtual server on the external VLAN with a single pool containing three HTTP pool members on the internal VLAN.
Which two locations are most appropriate to collect additional protocol analyzer data? (Choose two.)
An LTM Specialist has a single HTTPS virtual server doing SSL termination. No server SSL profile is defined. The pool members are on the internal VLAN answering on HTTP port 80. Users with certain browsers are experiencing issues.
Which two locations are most appropriate to gather packets needed to determine the SSL issue? (Choose two.)
A user is having issues with connectivity to an HTTPS virtual server. The virtual server is on the LTM device's external vlan, and the pools associated with the virtual server are on the internal vlan. An LTM Specialist does a tcpdump on the external interface and notices that the host header is incomplete.
In which location should the LTM Specialist put a traffic analyzer to gather the most pertinent data?
An application owner claims an LTM device is delaying delivery of an HTTP application. The LTM device has two VLANs, an internal and an external. The application servers reside on the internal VLAN. The virtual server and clients reside on the external VLAN.
With appropriate filters applied, which solution is most efficient for obtaining packet captures in order to investigate the claim of delayed delivery?
A client (10.10.1.30) connecting to an HTTPS virtual server (10.10.1.100) with a clientssl profile is getting an SSL error.
Which options will trace this issue?
An LTM device is deployed in a one-armed topology. The virtual server, clients, and web servers are connected on the LTM device internal VLAN. A client tries to connect to the virtual server and is unable to establish a connection. A packet capture from the LTM device internal VLAN shows that the HTTP request is being forwarded to the web server.
From which two additional locations should protocol analyzer data be collected? (Choose two.)
An LTM Specialist configures a new HTTP virtual server on an LTM device external VLAN. The web servers are connected to the LTM device internal VLAN. Clients trying to connect to the virtual server are unable to establish a connection. A packet capture shows an HTTP response from a web server to the client and then a reset from the client to the web server.
From which two locations could the packet capture have been collected? (Choose two.)
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:
Request:
GET /app/feed/current?uid=20145 HTTP/1.1
Host www.example.com
Accept-Encoding gzip, deflate
Connection: close
Response:
HTTP/1.1 302 Moved Temporarily

What is the problem?
