A set of servers is used for an FTP application as well as an HTTP website via separate BIG-IP Pools. The server support team reports that some servers are receiving a lot more traffic than others. Which Load Balancing Method should the BIG-IP Administrator apply to even out the connection count?

Refer to the exhibit. Due to a change in application requirements, a BIG-IP Administrator needs to modify the configuration of a Virtual Server to include a Fallback Persistence Profile. Which persistence profile type should the BIG-IP Administrator use for this purpose?

A BIG-IP Administrator makes a configuration change to a Virtual Server on the Standby device of an HA pair. The HA pair is currently configured with Auto-Sync Enabled. What effect will the change have on the HA pair configuration?

-- Exhibit – -- Exhibit -- Refer to the exhibit. A virtual server is set up on an LTM device as follows: Virtual server address 78.24.213.79 Default Persistence ProfilE. source_addr, 600s. Pool NamE. Pool1 Pool Members: 10.72.250.52:80 and 10.72.250.60:80 (both on Internal Vlan) There are several current connections to the virtual server, and pool member 10.72.250.52:80 has been set to a "Disabled" state. A tcpdump on the Internal Vlan shows traffic going to 10.72.250.52:80. How soon after the persistence table query was run can existing connections be refreshed/renewed to ensure that no requests are sent to 10.72.250.52?

-- Exhibit – -- Exhibit -- Refer to the exhibits. How should the LTM Specialist minimize the configuration?

A device group is made up of four members: LTM-A, LTM-B, LTM-C, and LTM-D. An LTM Specialist makes a configuration change on LTM-B. Later, a different LTM Specialist notices a "changes pending" message on all devices. When logged into LTM-D, the LTM Specialist attempts to config- sync to the device group. The sync operation fails. Why is the LTM Specialist on LTM-D unable to synchronize the configuration to the group?

Refer to the exhibit. An organization is reporting slow performance accessing their Intranet website, hosted in a public cloud. All employees use a single Proxy Server with the public IP of 104.219.110.168 to connect to the Internet. What should the BIG-IP Administrator of the Intranet website do to fix this issue?

A high-availability (HA) pair configuration uses only the hardwire serial cable connection to determine device state. A power outage occurs to the PDU powering the active unit. The standby unit takes over the active role as expected. How is the peer unit able to determine the active unit is unavailable?

-- Exhibit – Which two items can be consolidated to simplify the LTM configuration? (Choose two.)
