An LTM Specialist configures an HTTP monitor as follows:
ltm monitor http stats_http_monitor {
defaults-from http
destination *:*
interval 5
recv "Health check: OK"
send "GET /stats/stats.html HTTP/1.1\\r\\nHost:
www.example.com\\r\\nAccept-Encoding. gzip, deflate\\r\\nConnection:
close\\r\\n\\r\\n"
time-until-up 0
timeout 16
}
The monitor is marking all nodes as down. A trace of the HTTP conversation shows the following:
GET /stats/stats.html HTTP/1.1
Host: www.example.com
Accept-Encoding. gzip, deflate
Connection: close
HTTP/1.1 401 Authorization Required

An LTM Specialist configures two LTM devices in a high-availability pair with trusts established and device groups configured properly using network failover. After several months, the LTM Specialist notices that changes made to one LTM device do NOT cause the synchronization status to update to "changes pending," and this device does NOT synchronize with the device group. Which two steps should the LTM Specialist take to identify the issue? (Choose two.)
정답: A,D

Refer to the exhibit. A pool member fails the monitor checks for about 30 minutes and then starts passing the monitor checks. New traffic is Not being sent to the pool member. What is the likely reason for this problem?
정답: D
Refer to the exhibit. An LTM device is used to load balance web content over a secure channel.
The developers of the web content have done a trace using an HTTP profiler application. They believe that allowing the LTM device to compress traffic to the client will improve performance.
The client can utilize GZIP or deflate compression algorithms.
An LTM Specialist must implement the compression.
The LTM Specialist has completed the following actions:
1. Create the relevant profile.
2. Apply the relevant profile to the virtual server (VS).
After applying the relevant profile, the LTM device is failing to compress the traffic. Instead, the traffic is being served with an error.
