質問 # 195
Users cannot access a webserver and after the traffic is captured, the capture tool snows an ICMP packet that reports "time exceeded in-transit". What is the cause of this webserver access issue?

A. A router along the path is misrouting the packets in a wrong direction.
B. A router along the path has the wrong time.
C. The server is overloaded and the connection was not able to be processed in time.
D. The large distance between the server and the users means that the packets require too much time to reach the destination.

正解：A

解説：
If an ICMP packet reports "time exceeded in-transit," the TTL value of the IP packet reached zero. In normal operation, a network should not have a diameter so great that the TTL gets reduced to zero. The most common occurrence of this is when there is a routing loop.

質問 # 198
Which IP service synchronizes the time across devices?

A. NTP
B. SNMP
C. NAT
D. DNS

正解：A

解説：
Network Time Protocol (NTP) is used to synchronize the clocks of network devices to a common reference time. This is crucial for ensuring accurate time stamps in logs, coordinating time-sensitive operations, and maintaining consistent time across all devices in a network.
* NTP: Synchronizes clocks of network devices to ensure they have the same time, which is essential for accurate event logging and coordination.
* Other Protocols:
* DNS: Resolves domain names to IP addresses.
* SNMP: Used for monitoring network devices.
* NAT: Translates private IP addresses to public IP addresses.

Refer to the exhibit.

What does the command marked (2) do when it is run?

A. It does not delete the branch until it is merged.
B. It duplicates the test" branch.
C. It deletes the "test" branch only if a new branch is created.
D. It deletes the "test" branch.

正解：D

解説：
The command git branch -D test forcefully deletes the local branch named test, even if it has unmerged changes.
* Deleting Branches: git branch -D is used to delete a branch forcefully.
* Force Deletion: The -D flag forcefully deletes the branch regardless of its merge status.
Option C correctly describes the action of the command, which is to delete the test branch.

質問 # 204
Refer to the exhibit.

The definition of the YANG module and a RESTCONF query sent to a Cisco IOc XE device is shown. Which statement is correct if the RESTCONF interface responds with a 204 status code?

A. The query failed to set the logging seventy level due to an invalid path.
B. The query updated the logging seventy level or created it if not present on the device.
C. The query failed at retrieving the logging seventy level.
D. The query retrieved the logging seventy level.

正解：B

解説：
Reference: The HTTP status code 204 (No Content) indicates that the server successfully processed the request but is not returning any content. In the context of a RESTCONF PATCH operation, this means that the query updated the logging severity level or created it if it was not present on the device. The 204 No Content response confirms that the request was successfully processed without errors. More details on RESTCONF status codes can be found in the RFC 8040.

質問 # 210
Refer to the exhibit.

An engineer must configure a load balancer server. The engineer prepares a script to automate workflow by using Bash. The script install the nginx package, moves to the /optAtginx directory, and reads the sites M We (or further processing Based on the script workflow, which process is being automated within the loop by using the information mi sites txt?

A. creating a new Me Based on template .conf in the /etc/ngin/sites_enabled directory for each lie in the sites txt file. and then changing the file execution permission.
B. using the content of the file to create the template conf file. creating a Iink from the created file to the
/etc/nginx/files.enabled. and then changing the file execution permissions.
C. creating a Me per each the in sites txt with the information in template conf. creating a link for the previously created file. and then changing the ownership of the created files
D. using the information in the file to create a set of empty files in the /etchginx/sites_enabled directory and then assigning the owner of the file.

正解：C

解説：
The Bash script performs the following steps within the loop:
* Reads each line from sites.txt.
* Copies template.conf to a new file in the /etc/nginx/sites-available directory for each site.
* Creates a symbolic link to the new file in the /etc/nginx/sites-enabled directory.
* Changes the ownership of the new files to www-data.
This process creates a configuration file for each site, creates a link to enable the site, and ensures the correct permissions.
