dress with port and discovers that HTTPS access works to three servers of a network farm with IP 172.16.50.1 .2 and .4. but HTTPS access to the server with IP 172.16.50.3 does : work. Which problem type must be addressed as the cause for the case?
Answer : C
The issue described indicates that HTTPS (port 443) access is not working for one specific server (172.16.50.3) in the network farm, while it works for the others. This suggests that the transport port (port 443) might be blocked or filtered for this particular server.
Transport Port Blocking: Network firewalls or security groups might block specific ports for certain IP addresses.
Server Configuration: The server might not have the necessary configuration to accept HTTPS connections on port 443.
Troubleshooting: Verifying firewall rules, security group settings, and server configurations can help identify and resolve the issue.

A network engineer must improve the fabric discovery process in a data center. The engineer wants to check current ACI scripts in the myproject repository and clone them to a folder named aci. The engineer will optimize the scripts from the new folder. Which command performs this task on the Git repository?
A)
B)
C)
D)
Answer : D
To clone the 'myproject' repository from GitHub into a new folder named 'aci' for optimization, the correct command is:
git clone git@github.com:myproject aci
This command specifies the SSH URL of the repository (git@github.com
) and sets the target directory to 'aci.' The git clone command copies the repository to the local machine, creating a new directory named 'aci' where the repository's contents will be placed.
Refer to the exhibit.

The diff command is used to compare the contents of two files and display the differences. The -u option stands for 'unified' and shows the differences in a unified format, which includes the lines that differ between the two files along with a few lines of context.
When running the command diff -u file1.txt file2.txt, it compares the two files and shows the differences between them.
