D. http, clientssl, persistence

An LTM Specialist has noticed in the audit log that there are numerous attempts to log into the Admin

account. Theses attempts are sourced from a suspicious IP address range to the Configuration Utility of

the LTM device.

How should the LTM Specialist block these attempts?

A. add the permitted source IP addresses to the httpd allow list via tmsh

B. add the suspicious source IP addresses to the httpd deny list via tmsh

C. add the suspicious source IP addresses to the httpd deny list via Configuration Utility

D. add the permitted source IP addresses to the allow list via Configuration Utility

A Web Server Administrator uses a manual process to display a page when the service is down. Which feature on the LTM device should be used to automate the service down page?

A. Enable Request Queueing

B. Action on Service Down

C. Redirect Rewrite

D. Fallback Host

Exhibit.

The LTM devices LTM1 and LTM2 are configured in a Device Group (Sync Failover) with Network Failover configured on both the management and HA and Internal VLANS. and ConfigSync is confined in a Device Group (Sync Failover) with Network Failover and internal are tagged on a single trunk with subnets Connection Mirroring is configured on both the HA interlace directly connected between LTM1 and LTM2, and the management interlace is connected to a management switch. The LTM devices have four Traffic Groups defined, and both LTM devices are healthy and capable of passing traffic for any of the Traffic Groups. An LTM Specialist disconnects the cable for the HA network in an effort to test failover. Which HA functionality works in this case?

A. ConfigSync does NOT work. Connection Mirroring floes NOT work.

B. ConfigSync works Connection Mirroring works

C. ConfigSync works. Connection Mirroring docs NOT work

D. ConfigSync does NOT work; Connection Mirroring works

An HA pair of LTM devices that load balance multiple HTTPS applications utilizes highly customized RAM Cache and compression profiles on each virtual server. The LTM Specialist who is administering the HA pair regularly observes entines in the log similar to the following: tmm tmm I708S1 011e0002.4. sweeper_update: aggressive mode activated (117504/138240 pages) No DoS attacks arc occurring. No user problems have been reported. Which step should the LTM Specialist take to help mitigate the issue?

A. change the Adaptive Reaping High watermark

B. change the Adaptive Reaping Low watermark

C. allocate less memory to the RAM cache feature

D. use a OneConnect profile

An LTM device receives a response string containing "error" Which monitor type and parameter will mark the HTTP server as down?

B. HTTP monitor and Receive String "error'' ... flag is up

C. HTTP monitor. Receive String "down", and set the Reverse option to Yes .... flag is

D. HTTP monitor and Receive Disable String "error'' .... flag is disable

Refer to the exhibit.

The http monitor is applied to a pool. All members are enabled. One server responds as follows.

What is the resulting status of this poo! member?

A. Offline (Disabled)

B. Offline (Enabled)

C. Unavailable (Disabled)

D. Available (Enabled)

An application is expected to maintain more than 100,000 concurrent TCP connections to a single pool

member.

What is an appropriate SNAT configuration in this situation?

A. A SNAT pool with 4 IP addresses

B. SNAT automap enabled

C. A static SNAT

D. A SNAT pool with IP address
