Answer:

Explanation:
See the step by step complete solution below
Explanation:
To validate routing between networks hosting Workstation A and File Server 2, follow these steps:
Step-by-Step Solution
Review Routing Tables:
Check the routing tables of Router A, Router B, and Router C to identify any missing routes.
Identify Missing Routes:
Ensure that each router has routes to the networks on which Workstation A and File Server 2 are located.
Add Static Routes:
If a route is missing, add a static route to the relevant destination network via the correct interface.

NEW QUESTION # 18
A user connects to a corporate VPN via a web browser and is able to use TLS to access the internal financial system to input a time card. Which of the following best describes how the VPN is being used?

  • A. Full tunnel
  • B. Clientless
  • C. Site-to-site
  • D. Client-to-site

Answer: B

Explanation:
The scenario describes a user connecting to a corporate VPN via a web browser using TLS to access an internal system. This setup is best described as a "clientless" VPN. Clientless VPNs do not require a VPN client to be installed on the user's device; instead, they rely on a standard web browser to establish the connection. This method is particularly useful for providing secure, remote access to applications through a web interface without the need for additional software installations.


NEW QUESTION # 19
A network engineer is designing a secure communication link between two sites. The entire data stream needs to remain confidential. Which of the following will achieve this goal?

  • A. ESP
  • B. AH
  • C. IKE
  • D. GRE

Answer: A

Explanation:
* Definition of ESP (Encapsulating Security Payload):
* ESP is a part of the IPsec protocol suite designed to provide confidentiality, integrity, and authenticity of data by encrypting the payload and optional ESP trailer.
* Ensuring Confidentiality:
* Encryption: ESP encrypts the payload, ensuring that the data remains confidential during transmission. Only authorized parties with the correct decryption keys can access the data.
* Modes of Operation: ESP can operate in transport mode (encrypts only the payload) or tunnel mode (encrypts the entire IP packet), both providing strong encryption to secure data between sites.
* Comparison with Other Protocols:
* GRE (Generic Routing Encapsulation): A tunneling protocol that does not provide encryption or security features.
* IKE (Internet Key Exchange): A protocol used to set up a secure, authenticated communications channel, but it does not encrypt the data itself.
* AH (Authentication Header): Provides integrity and authentication for IP packets but does not encrypt the payload.
* Implementation:
* Use ESP as part of an IPsec VPN configuration to encrypt and secure communication between two sites. This involves setting up IPsec policies and ensuring both endpoints are configured to use ESP for data encryption.

* CompTIA Network+ study materials on IPsec and secure communication protocols.


NEW QUESTION # 20
Which of the following routing protocols is most commonly used to interconnect WANs?

  • A. EIGRP
  • B. IGP
  • C. BGP
  • D. OSPF

Answer: C

Explanation:
Border Gateway Protocol (BGP): BGP is the most commonly used routing protocol for interconnecting WANs, especially across the internet. It is used for exchanging routing information between autonomous systems (AS), making it the backbone protocol for large-scale WANs.


NEW QUESTION # 21
......

We always learned then forget, how to solve this problem, the answer is to have a good memory method, our N10-009 exam question will do well on this point. Our N10-009 real exam materials have their own unique learning method, abandon the traditional rote learning, adopt diversified memory patterns, such as the combination of text and graphics memory method, to distinguish between the memory of knowledge. Our N10-009 learning reference files are so scientific and reasonable that you can buy them safely.
