[单选题]Refer to the exhibit.
The LTM devices LTM3 and LTM2 have four Traffic Groups defined with approximately the sar of failover objects defined in each group.
- Traffic Groups A and C have Default Device set to LTM1
- Traffic Groups Band D have Default Device set to LTM2.
- Traffic Groups B and C do NOT have Auto Failback enabled. Traffic Groups A and D have Auto Failback
Enabled with a timeout value of 60 seconds.
- Traffic Groups A and D have Auto Fallback enabled with a timeout value of 60 seconds. Both LTM devices are healthy and able to pass traffic for any Traffic Group.
LTM1 loses connectivity on interface 1.4. The LTM Specialists notified 60 seconds after the interface goes down.

D. define active subnets and assign a name to certain subnets
[单选题]An LTM Specialist observes decreased performance and intermittent connection reap LTM system.
Based on the configuration, which action will address these issues?
A. Use an optimized TCP profile.
B. Use a FastL4 profile on the virtual server
C. Use a default caching profile on the virtual server.
D. Use a shorter idle timeout on the TCP profile.
[单选题]An LTM Specialist reports that an application si no longer reachable after it has been upgraded. Nothing has been changed in the configuration on the LTM device.
The logs indicates that health monitors to all servers have failed as shown:
What should the LTM Specialist verify next?
A. That the TCP hand shake with the servers is stall completed using tcpdump
B. That the custom receive string for the HTTP monitor has changed with the upgrade
C. That the can still ping the servers from te BIG_ IP device.
D. That the firewall between the BIG-ip device and servers is still allowing HTTP
Explanation:
The log shows that tcp detection is normal, but http detection is abnormal. So we should pay attention to the detection problem of http level
