Which step should an LTM Specialist take to utilize AVR?

An LTM device has a virtual server configured as a Performance Layer 4 virtual listening on 0.0.0.0:0 to perform routing of packets to an upstream router. The client machine at IP address 192.168.0.4 is attempting to contact a host upstream of the LTM device on IP address 10.0.0.99.

The network flow is asymmetrical, and the following TCP capture displays:

# tcpdump -nnni 0.0 'host 192.168.0.4 and host 10.0.0.99'

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

listening on 0.0, link-type EN10MB (Ethernet), capture size 96 bytes

05:07:55.499954 IP 192.168.0.4.35345 > 10.0.0.99.443: S 3205656213:3205656213(0) ack 3267995082 win 1480

05:07:55.499983 IP 10.0.0.99.443 > 192.168.0.4.35345: R 1:1(0) ack 1 win 0

05:07:56.499960 IP 192.168.0.4.35345 > 10.0.0.99.443: S 3205656213:3205656213(0) ack 3267995082 win 1480

05:07:56.499990 IP 10.0.0.99.443 > 192.168.0.4.35345: R 1:1(0) ack 1 win 0

4 packets captured

Which option within the fastL4 profile needs to be enabled by the LTM Specialist to prevent the LTM device from rejecting the flow?

Which two servers are missing two frequently used URLs? (Choose two.)

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 has set up a custom SNMP alert.

Which command line tool should the LTM Specialist use to test the alert?

The virtual server is listening on port 443.

What is the solution to the problem?

The pool members are serving up simple static web content.

The current virtual server configuration is given as follows:

tmsh list ltm virtual simple

ltm virtual simple {

destination 10.10.10.10:80

ip-protocol tcp

mask 255.255.255.255

profiles {

http { }

httpcompression { }

oneconnect { }

tcp { }

}

snat automap

vlans-disabled

}

tmsh list ltm pool simple_pool

ltm pool simple_pool {

members {

10.10.10.11:80 {

address 10.10.10.11 }

10.10.10.12:80 {

address 10.10.10.12 }

10.10.10.12:80 {

address 10.10.10.13 }

}

}

Which three objects in the virtual server configuration can be removed without disrupting functionality of the virtual server? (Choose three.)

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?

While investigating the cause of a device failover, an LTM Specialist discovers the following events in /var/log/ltm:

01010029:5: Clock advanced by 518 ticks

01010029:5: Clock advanced by 505 ticks

01010029:5: Clock advanced by 590 ticks

01010029:5: Clock advanced by 568 ticks

01010029:5: Clock advanced by 1681 ticks

01010029:5: Clock advanced by 6584 ticks

01140029:5: HA daemon_heartbeat tmm fails action is failover and restart.

010c0026:5: Failover condition, active attempting to go standby.

Which issue caused the failover?

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?
