A. Available (Disabled)

B. Offline (Disabled)

C. Offline (Enabled)

D. Available (Enabled)

A. /var/log/tmm

B. /var/log/audit

C. /var/log/ltm

D. /var/log/syslog

Question 4

Clients report that they cannot reach the virtual server vs-production on port 80, but are able to ping the virtual server address. The configuration is shown below:
Plaintext
ltm virtual vs-production {
destination 10.99.20.50:http
ip-protocol tcp
mask 255.255.255.255
profiles {
http {}
tcp {}
}
source 192.168.0.0/16
translate-address enabled
translate-port enabled
vlans {
external
}
vlans-enabled
}
What is the cause?

A. The client comes from an unallowed subnet.

B. The virtual server is disabled.

C. The virtual server does NOT listen on port 80.

D. The client uses an old browser.

Question 5

Refer to the exhibit.

A BIG-IP Administrator configured a virtual server with a pool of 3 members and selected the Round Robin load balancing method to evenly distribute traffic across the pool members. During initial testing, traffic was not evenly distributed and the pool member 172.16.20.3 received more traffic than the other pool members.
Refer to the exhibit and the virtual server configuration provided below:
Plaintext
ltm virtual http.vs {
destination 10.10.1.100:http
ip-protocol tcp
mask 255.255.255.255
persist {
source_addr { default yes }
}
pool http.pool
profiles {
tcp{}
}
serverssl-use-sni disabled
source 0.0.0.0/0
source-address-translation {
type automap
}
translate-address enabled
}
What is the most likely cause of this behavior?

A. Pool members' ratio settings are causing the uneven traffic distribution

B. A persistence profile assigned to the virtual server can cause uneven load balancing

C. Automap source address translation can cause uneven load balancing

D. Round Robin requires an HTTP profile to work efficiently

A BIG-IP Administrator suspects that one of the BIG-IP device power supplies is experiencing power outages. Which log file should the BIG-IP Administrator check to verify the suspicion?

A. /var/log/kern.log

B. /var/log/audit

C. /var/log/daemon.log

D. /var/log/ltm

Correct Answer: D

A. MCPD transactions

B. Configuration utility

C. iControl transactions

D. APM sessions

Question 8

The BIG-IP appliance fails to boot. The BIG-IP Administrator needs to run the End User Diagnostics (EUD) utility to collect data to send to F5 Support. Where can the BIG-IP Administrator access this utility?

A. Console Port

B. External VLAN interface

C. Internal VLAN interface

D. Management Port

Question 9

A BIG-IP Administrator is informed that traffic on Interface 1.1 is expected to increase over the maximum bandwidth capacity on the link. There is a single VLAN on the Interface. What should the BIG-IP Administrator do to increase the total available bandwidth?

A. Increase the MTU on the VLAN using Interface 1.1

B. Create a trunk object with two Interfaces

C. Assign two Interfaces to the VLAN

D. Set the media speed of Interface 1.1 manually
