Question 42
An engineer is trying to copy an IOS file from one router to another router by using TFTP. Which two actions are needed to allow the file to copy? (Choose two.)
Copy the file to the destination router with the copy tftp: flash: command
Enable the TFTP server on the source router with the tftp-server flash: <filename> command
TFTP is not supported in recent IOS versions, so an alternative method must be used
Configure a user on the source router with the username tftp password tftp command
Configure the TFTP authentication on the source router with the tftp-server authentication local command
Question 43
Refer to the exhibit.
Users report that IP addresses cannot be acquired from the DHCP server. The DHCP server is configured as shown. About 300 total nonconcurrent users are using this DHCP server, but none of them are active for more than two hours per day. Which action fixes the issue within the current resources?
Modify the subnet mask to the network 192.168.1.0 255.255.254.0 command in the DHCP pool
Configure the DHCP lease time to a smaller value
Configure the DHCP lease time to a bigger value
Add the network 192.168.2.0 255.255.255.0 command to the DHCP pool
Question 44
Refer to the exhibit.
ISP 1 and ISP 2 directly connect to the Internet. A customer is tracking both ISP links to achieve redundancy and cannot see the Cisco IOS IP SLA tracking output on the router console.
Which command is missing from the IP SLA configuration?
Start-time 00:00
Start-time 0
Start-time immediately
Start-time now

Question 45
Refer to the exhibit.
An administrator noticed that after a change was made on R1, the timestamps on the system logs did not match the clock. What is the reason for this error?
An authentication error with the NTP server results in an incorrect timestamp.
The keyword localtime is not defined on the timestamp service command.
The NTP server is in a different time zone.
The system clock is set incorrectly to summer-time hours.
Question 46
A network engineer is investigating a flapping (up/down) interface issue on a core switch that is synchronized to an NTP server. Log output currently does not show the time of the flap. Which command allows the logging on the switch to show the time of the flap according to the clock on the device?
service timestamps log uptime
clock summer-time mst recurring 2 Sunday mar 2:00 1 Sunday nov 2:00
service timestamps log datetime localtime show-timezone
clock calendar-valid
By default, Catalyst switches add a simple uptime timestamp to logging messages. This is a cumulative counter that shows the hours, minutes, and seconds since the switch has been booted up
Question 47
When provisioning a device in Cisco DNA Center, the engineer sees the error message "Cannot select the device. Not compatible with template".
What is the reason for the error?
The template has an incorrect configuration.
The software version of the template is different from the software version of the device.
The changes to the template were not committed.
The tag that was used to filter the templates does not match the device tag.
If you use tags to filter the templates, you must apply the same tags to the device to which you want to apply the templates. Otherwise, you get the following error during provisioning: ?Cannot select the device. Not compatible with template.?

Question 48
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?
The device must be resynced to Cisco DNA Center.
The software image for the device is in install mode.
The device has lost connectivity to Cisco DNA Center.
The software image for the device is in bundle mode
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.

Question 49
An engineer configured the wrong default gateway for the Cisco DNA Center enterprise interface during the install. Which command must the engineer run to correct the configuration?
sudo maglev-config update
sudo maglev install config update
sudo maglev reinstall
sudo update config install
Question 50
Refer to the exhibit.
An administrator that is connected to the console does not see debug messages when remote users log in. Which action ensures that debug messages are displayed for remote logins?
