Refer to the exhibit.
An LTM Specialist has created a virtual server to balance connections to a pool of application servers and offload SSL decryption. Clients connect to the application at https://www.example.com/. The virtual server is configured with a clientssl profile but no serverssl profile. The application servers are listening on ports
80 and 443. Users are unable to connect to the application through the virtual server but are able to connect directly to the application server.
What is the root cause of the error?

  • A. The application servers are redirecting users to HTTPS.
  • B. The LTM device is chunking responses.
  • C. The LTM device is redirecting users to HTTPS.
  • D. The pool members are configured with the wrong port.

正解：A


質問 # 78
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
Date Wed, 17 Oct 2012 18:45:52 GMT
Server Apache
Location https://example.com/login.jsp
Content-Encoding gzip
Content-Type text/html;charset=UTF-8
Set-CookiE. JSESSIONID=261EFFBDA8EC3036FBCC22D991AC6835; Path=/app/feed/current?uid=20145 What is the problem?

  • A. The HTTP monitor does NOT support monitoring jsp pages.
  • B. The request does NOT include a User-Agent header.
  • C. The request includes an Accept-Encoding so the server is responding with a gzipped result and LTM monitors CANNOT handle gzipped responses.
  • D. The request does NOT include any cookies and the application is expecting a session cookie.

正解：D

A company uses a complex piece of client software that connects to one or more virtual servers (VS) hosted on an LTM device. The client software is experiencing issues. An LTM Specialist is tasked with finding the cause of the problem.
The LTM Specialist has the tcpdump extract and knows the client software has at least one connection to a VS on port 1990. However, when a tcpdump runs on the internal VLAN, there is no record of port 1990 in the tcpdump.
Why is there no record of port 1990 in the tcpdump?

  • A. The LTM device drops the connection.
  • B. The LTM device performs a Network Address Translation (NAT).
  • C. Port 1990 is a well-known port, so its use is restricted.

How should the LTM Specialist resolve this issue?

  • A. Enable SNAT Automap on both virtual servers.
