By default, syslog and debug messages are stamped by UTC, regardless of the time zone that device
configured. You should append localtime key word to "service timestamp {log | debug} datetime msec" global command to change that behavior.

While working with software images, an engineer observes that Cisco DNA Center cannot upload its software image directly from the device.
Why is the image not uploading?
- A . The device must be resynced to Cisco DNA Center.
- B . The software image for the device is in install mode.
- C . The device has lost connectivity to Cisco DNA Center.
- D . The software image for the device is in bundle mode
B
Explanation:
Upload Software Images for Devices in Install Mode
The Image Repository page might show a software image as being in Install Mode. When a device is in Install Mode, Cisco DNA Center is unable to upload its software image directly from the device. When a device is in install mode, you must first manually upload the software image to the Cisco DNA Center repository before marking the image as golden, as shown in the following steps.
