質問 1：
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?
A. internal VLAN
B. server
C. client machine
D. external VLAN
正解：C

質問 2：
There are three servers in the pool: 172.16.20.1, 172.16.20.2, and 172.16.20.3, with the virtual IP address 10.0.20.88.
A user CANNOT connect to an HTTP application. To understand the problem and find a solution, the LTM Specialist runs two concurrent traces on the LTM device, with the following results:
Trace on client side:
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

What should the LTM Specialist do to solve the problem?
A. Configure the virtual server to use SNAT.
B. Enable the virtual server.

D. Modify the monitor of the pool.
正解：A

質問 3：
-- Exhibit- -- Exhibit -

Refer to the exhibit.
A server administrator notices that one server is intermittently NOT being sent any HTTP requests. The server logs display no issues. The LTM Specialist notices log entries stating the node (172.16.20.1) status cycling between down and up. The pool associated with the virtual server (10.10.1.100) has a custom HTTP monitor applied.
Which tcpdump filter will help trace the monitor?
A. tcpdump -i external port 80 and host 172.16.20.1
B. tcpdump -i internal port 80 and host 172.16.1.31
C. tcpdump -i external port 80 and host 10.10.1.100
D. tcpdump -i internal port 80 and host 172.16.1.33
正解：B

10.10.10.12:80
{
address 10.10.10.13 }
}
}

A. httpcompression
B. snat automap
C. tcp
D. oneconnect

質問 5：
An LTM Specialist needs to rewrite text within an HTML response from a web server. A client is sending the following HTTP request:
GET / HTTP/1.1 Host: www.example.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/20100101 Firefox/16.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-LanguagE.en-US,en;q=0.5 Accept-EncodinG.gzip, deflate Cache-Control: no-cache Connection: keep-alive CookiE.somecookie=1
HTTP/1.1 200 OK Server: Apache/2.2.15 (Unix) Last-ModifieD.Wed, 12 Aug 2009 00:00:30 GMT Accept-Ranges: bytes Content-LengtH.1063 X-Cnection: close Content-TypE.text/html; charset=UTF-8 Vary: Accept-Encoding Content-EncodinG.gzip Connection: Keep-Alive
Although a stream profile has been added to the virtual server, the content within the HTTP response is NOT being matched and therefore NOT modified.
Which header field is contributing to the issue?
A. User-Agent Value
B. Cookie content
C. HTTP Method
D. Accept-Encoding header
正解：D
