when HTTP_RESPONSE {

if { [HTTP::is_3xx] } {

log local0. "redirecting client ip address [IP::addr [IP::remote_addr]]"

}

when HTTP_REQUEST {

if { [HTTP::is_301] } {

log local0. "redirecting client ip address [IP::addr [IP::remote_addr]]"

}

when HTTP_REQUEST {

if { [HTTP::is_redirect] } {

log local0. "redirecting client ip address [IP::addr [IP::remote_addr]]"

}

when HTTP_RESPONSE {

if { [HTTP::is_redirect] } {

log local0. "redirecting client ip address [IP::addr [IP::remote_addr]]"

}

Question # 54

-- Exhibit --

Refer to the exhibit.

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 must determine the cause of the problem. The LTM Specialist has the tcpdump extract. The client loses connection with the LTM device.

Where is the reset originating?

Options:

the local switch

the application server

the device initiating the connection

the destination device of the initial connection

Questions # 55:

An LTM Specialist is experiencing issues in a failover event. Certain long-lasting FTP event. Certain long-lasting FTP connections using a single node pool are forced to reconnect. The bigip.conf extract isshown:

Question # 55

What does the LTM Specialist need to change in the configuration to avoid this issue?

Options:

snatpool

persistence mirroring

connection mirroring

ftp profile

Questions # 56:

A pool with a default connection limit is configured to use Round Robin as the load balancing method. An LTM Specialist needs to ensure that the LTM device selects a serverwith the fewest number of connections when new clients connect. Another pool is using the same set of backend servers.

Which load balancing-method should the pool be changed to?

Options:

Weighted Least Connections (node]

Weighted Least Connections (member)

Least Connections

Questions # 57:

A design requires the LTM device to become HA standby when the one of the two physical interface on the External trunk is down the Externaltrunk is an interface on the External VLAN

Which TMOS command enables this behavior?

Options:

tmsh modify net van External failsafe enabled

tmsh create sys ha-group External trunks add Externally

tmsh create sys ha-group External trunks add External threshold 2 weight 101)

tmsh create sys ha-group External trunks add ( External( attribute percent up-members 100))

Questions # 58:

There is a fault with an LTM device load balanced trading application that resides on directly connected VLAN vlan-301. The application virtual server is 10.0.0.1:80 with trading application backend servers on subnet 192.168.0.0/25. The LTM Specialist wants to save a packet capture with complete payload for external analysis.

Which command should the LTM Specialist execute on the LTM device command line interface?

Options:

tcpdump -vvv -w /var/tmp/trace.cap 'net 192.168.0.0/25'

tcpdump -vvv -s 0 -w /var/tmp/trace.cap 'net 192.168.0.0/25'

tcpdump -vvv -nni vlan-301 -w /var/tmp/trace.cap 'net 192.168.0.0/25'

Questions # 59:

An LTM Specialist upgrades the switchinginfrastructure and the backend servers on the LAN segments.

The LTM Specialist notices a 20% memory usage increase on the BIG-IP device while handling the same number of concurrent connections.

A comparison of statistics pre-upgrade and post-upgrade showsa significant reduction on the following:

-RTT between the BIG-IP device and the backend servers

-Packet drops in the switch

Time to First Byte (TTFB)

The LTM Specialist is concerned with the scalability of the number of concurrent connections with the newmemory usage.

Which setting should be changed to reduce the memory usage on the BIG-IP device?

Options:

Reduce the proxy buffer high setting on the server-side TCP profile

Increase the receive window of the client-side TCP profile

Increase the proxy buffer high setting on the server-side TCP profile

Reduce the idle of the client-side TCP profile

Questions # 60:

An LTM Specialist needs to deploy a virtual server that will load balance traffic targeting https://register.example.com to a set of three web servers. Persistence needs to be ensured. No persistence mirroring is allowed SSL offloading is required.

A fourth web server with fewer resources will be used to handle requests from engine bots to https://register.example.comvrobots.txt by an iRule. The (Rule will use the HTTP_REQUEST event. .

What are the required profile and persistence settings to implement this
