NO.89 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”

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

Explanation/Reference:

NO.100 — Exhibit –

— Exhibit —
Refer to the exhibit.
An LTM Specialist has created a virtual server to load balance traffic to a pool of HTTPS servers. The servers use client certificates for user authentication. The virtual server has clientssl, serverssl, and http profiles enabled. Clients are unable to connect to the application through the virtual server. Clients are able to connect to the application servers directly.
What is the root cause of the problem?

The application server does NOT support 2048-bit keys.

The clientssl profile is NOT set to require a client certificate.

The LTM device does NOT trust the issuing CA of the client certificate.

The application server does NOT see the client certificate due to SSL offload.

NO.101 An FTP monitor is NOT working correctly.
Which three pieces of information does the LTM Specialist need to provide to ensure a properly working FTP monitor? (Choose three.)

alias

File path

username

password

FTP server port

FTP server IP address

NO.102 An LTM Specialist must perform a packet capture on a virtual server with an applied standard FastL4 profile.
The virtual server 10.0.0.1:443 resides on vlan301.
Which steps should the LTM Specialist take to capture the data payload successfully while ensuring no other virtual servers are affected?

The standard FastL4 profile should have PVA acceleration disabled. Then the packet capture tcpdump -ni vlan301 should be executed on the command line interface.

The packet capture tcpdump -ni vlan301 should be executed on the command line interface. There is no need to change profiles or PVA acceleration.

A new FastL4 profile should be created and applied to the virtual server with PVA acceleration disabled.
Then the packet capture tcpdump -ni vlan301 should be executed on the command line interface.

The LTM device is under light load. The traffic should be mirrored to a dedicated sniffing device. On the sniffing device, the packet capture tcpdump -ni vlan301 should be executed.

NO.103 — Exhibit- — Exhibit –

Refer to the exhibit.
Which URL should be reported to the server/application team as getting user-visible errors?

/env.cgi

/page14.cgi

/reflector.php

NO.104 What is the effect of an iRule error such as referencing an undefined variable?

The iRule execution will continue with the next statement.

The execution of the current event within the iRule will be terminated.

The iRule execution will be terminated, and both the client and server side connections will be reset.

The connection will continue, but the iRule will NOT be executed again for the lifetime of the connection.

NO.105 An LTM device has been configured to log the reasons for generating TCP RST packets.
The following log entry occurs:
“01230140:3: RST sent from 192.168.1.100:80 to 192.168.1.124:39272, [0x112d82a:1721] {peer} TCP RST from remote system.”
Which condition will trigger this log entry?

A virtual server connection limit has been reached.

The host at the other end terminated the TCP connection.

The LTM device reset the connection because no pool members are available.

The LTM device has reached the maximum number of allowed attempts to send the data segment to the affected TCP connection.
