A BIG-IP Administrator is checking the BIG-IP device for known vulnerabilities. What should the 8IG-IP Administrator upload to BIG-IP iHealth for further analysis?

Which log file should the BIG-IP Administrator check to determine if a specific user tried to log in to the 8IG-IP Configuration by utility?

A BIG-IP Administrator reviews the log files to determine the cause of a recent problem and finds the

following entry.

Mar 27.07.58.48 local/BIG-IP notice mcpd {5140} 010707275 Pool member 172.16.20.1.10029 monitor

status down.

What is the cause of this log message?

A BIG-IP Administrator adds new Pool Members into an existing, highly utilized pool. Soon after, there are reports that the application is failing to load for some users. What pool level setting should the BIG-IP Administrator check?

Which statement is true regarding failover?

The ICMP monitor has been assigned to all nodes. In addition, all pools have been assigned custom monitors. The pool is marked available. If a pool is marked available (green) which situation is sufficient to cause this?

Refer to the exhibit.

During a planned upgrade lo a BIG-IP HA pair running Active/Standby, an outage to application traffic is reported shortly after the Active unit is forced to Standby Reverting the flower resolves the outage. What should the BIG-IP Administrator modify to avoid an outage during the next for over event?

Assume a client's traffic is being processed only by a NAT; no SNAT or virtual server processing takes place. Also assume that the NAT definition specifies a NAT address and an origin address while all other settings are left at their defaults. If a client were to initiate traffic to the NAT address, what changes, if any, would take place when the BIG-IP processes such packets?

A site wishes to perform source address translation on packets from some clients but not others. The determination is not based on the client's IP address, but on the virtual servers their packets arrive on. What could best accomplish this goal?

Refer to the exhibit.

How are new connections load balanced?

A BIG-IP Administrator needs to configure the BIG-IP system to perform load balancing for FTP servers

running passive mode FTP.

How should the administrator configure the Virtual Server to perform this load balancing?

All pool members are online. All other virtual server settings are at default What might after the load balancing behavior?

A VLAN has the following objects configured:

Self-IP 10.10.10.100 with port lockdown set to Allow default

Virtual server 10.10.10.0/24 port forwarding virtual server

Global destination NAT forwarding 10.10.10.100 to internal server 172.168.10.100

Which object will process this request when https://10.10.10.100 is entered into a browser?

A pool of four servers has been partially upgraded for two new servers with more memory and CPU capacity. The BIG-IP Administrator must change the load balance method to consider more connections for the two new servers. Which load balancing method considers pool member CPU and memory load?

A virtual server is defined per the charts. The last five client connections were to members C, D, A, B, B. Given the conditions shown in the above graphic, if a client with IP address 205.12.45.52 opens a connection to the virtual server, which member will be used for the connection.

Active connections to pool members are unevenly distributed. The load balancing method is Least Connections (member) Priority Group Activation is disabled. What is a potential cause of the event distribution?
