1. Question 1

   Which tool simulates a network that runs Cisco equipment?

   ACisco Prime Infrastructure
   

   BVMware
   

   CDocker
   

   DCML
   

   Correct answer: D

   Cisco Modeling Labs (CML) is a network simulation tool that allows users to create, configure, and simulate networks with Cisco devices and topologies.

   Cisco Modeling Labs (CML): CML provides a virtual environment where users can simulate network topologies and devices, including routers, switches, and other network components.

   Simulation and Testing: CML allows users to test configurations, troubleshoot network issues, and study network behavior in a controlled environment.

2. Question 2

   What is the difference between YAML and JSON data structure?

   AYAML uses spaces; JSON uses parentheses
   

   BYAML uses indentation; JSON uses brackets and braces
   

   CYAML uses brackets and braces; JSON uses indentation
   

   DYAML uses parentheses; JSON uses spaces
   

   Correct answer: B

   The difference between YAML and JSON in terms of data structure representation is that YAML uses indentation to indicate structure, while JSON uses brackets and braces.

   A . YAML uses spaces; JSON uses parentheses - Incorrect. JSON does not use parentheses. B. YAML uses indentation; JSON uses brackets and braces - Correct. YAML relies on indentation for structure, whereas JSON uses brackets and braces. C. YAML uses brackets and braces; JSON uses indentation - Incorrect. This is the opposite of the correct statement. D. YAML uses parentheses; JSON uses spaces - Incorrect. Neither format uses these exclusively.

3. Question 3

   Which detail is included in a routing table?

   AIP protocol
   

   BBroadcast address
   

   CTCP or UDP port number
   

   DDestination next hop or outgoing interface
   

   Correct answer: D

   A routing table contains critical information used by routers to determine the best path for forwarding packets. The essential details included in a routing table are:

   Destination network: The IP address of the destination network.

   Next hop: The IP address of the next hop router or the outgoing interface to reach the destination network.

   Metric: The cost associated with the path to the destination network, used to select the best route.

   Route type: The type of route (e.g., directly connected, static, dynamic).

   
   

4. Question 4

   A developer pushes an application to production. The application receives a webhook over HTTPS without a secret. The webhook information contains credentials to service in cleartext. When the information is received, it is stored in the database with an SHA-256 hash. Credentials to the database are accessed at runtime through the use of a vault service. While troubleshooting, the developer sets the logging to debug to view the message from the webhook. What is the security issue in this scenario?

   ADatabase credentials should be accessed by using environment variables defined at runtime.
   

   BDuring the transport of webhook messages, the credentials could be unencrypted and leaked.
   

   CDuring logging, debugging should be disabled for the webhook message.
   

   DHashing the credentials in the database is not secure enough; the credentials should be encrypted.
   

   Correct answer: B

   The main security issue in this scenario is the transmission of credentials in cleartext over HTTPS. Even though HTTPS provides a secure transport layer, the credentials should still be protected, such as by using secrets or encryption. Additionally, setting logging to debug and potentially exposing these credentials in logs is also a security concern.

   Cleartext Credentials: Sending credentials in cleartext within the webhook payload can expose them if HTTPS is not configured correctly or if intercepted by an attacker.

   Debug Logging: Enabling debug logging can expose sensitive information, including credentials, in logs.

   Option B highlights the risk of transmitting credentials unencrypted over HTTPS, which can lead to credential leakage.

5. Question 5

   Refer to the exhibit.

   

   A network engineer must copy the ''config.txt'' file from directory TEST to directory PROD. The copied file must also be renamed into ''current.txt''. Which command must be used to accomplish these tasks?

   Acp ./PROD/current.txt ./TEST/config.txt
   

   Bcp ./TESTi/current.txt ./PROD/config.txt
   

   Ccp ./PROD/config.txt ./TEST/current.txt
   

   Dcp ./TEST/config.txt ./PROD/current.txt
   

   Correct answer: D

   To copy a file from one directory to another and rename it in the process, the cp (copy) command in Linux can be used with the appropriate source and destination paths:

   Command Breakdown:

   cp: The copy command.

   ./TEST/config.txt: The source file path.

   ./PROD/current.txt: The destination file path with the new name.

   Thus, the correct command to achieve this task is: cp ./TEST/config.txt ./PROD/current.txt
