2022 WAN chapter 7 questions well solved

What is an IPsec protocol that provides data confidentiality and authentication for IP packets? IKE RSA ESP AH ESP 2 Refer to the exhibit. A tunnel was implemented between routers R1 and R2. Which two conclusions can be drawn from the R1 command output? (Choose two.) A GRE tunnel is being used. This tunnel mode provides encryption. The data that is sent across this tunnel is not secure. This tunnel mode does not support IP multicast tunneling. This tunnel mode is not the default tunnel interface mode for Cisco IOS software. A GRE tunnel is being used. The data that is sent across this tunnel is not secure. 00:57 01:13 Which two scenarios are examples of remote access VPNs? (Choose two.) A toy manufacturer has a permanent VPN connection to one of its parts suppliers. A mobile sales agent is connecting to the company network via the Internet connection at a hotel. A small branch office with three employees has a Cisco ASA that is used to create a VPN connection to the HQ. An employee who is working from home uses VPN client software on a laptop in order to connect to the company network. All users at a large branch office can access company resources through a single VPN connection. An employee who is working from home uses VPN client software on a laptop in order to connect to the company network. A mobile sales agent is connecting to the company network via the Internet connection at a hotel. Which remote access implementation scenario will support the use of generic routing encapsulation tunneling? a mobile user who connects to a SOHO site a mobile user who connects to a router at a central site a central site that connects to a SOHO site without encryption a branch office that connects securely to a central site a central site that connects to a SOHO site without encryption A network design engineer is planning the implementation of a cost-effective method to interconnect multiple networks securely over the Internet. Which type of technology is required? a leased line a VPN gateway a GRE IP tunnel a dedicated ISP a VPN gateway How is "tunneling" accomplished in a VPN? New headers from one or more VPN protocols encapsulate the original packets. Packets are disguised to look like other types of traffic so that they will be ignored by potential attackers. All packets between two hosts are assigned to a single physical medium to ensure that the packets are kept private. A dedicated circuit is established between the source and destination devices for the duration of the connection. New headers from one or more VPN protocols encapsulate the original packets. What is the purpose of utilizing Diffie-Hellman (DH) algorithms as part of the IPsec standard? DH algorithms allow unlimited parties to establish a shared secret key that is used by encryption and hash algorithms. DH algorithms allow two parties to establish a shared public key that is used by encryption and hash algorithms. DH algorithms allow two parties to establish a shared secret key that is used by encryption and hash algorithms. DH algorithms allow unlimited parties to establish a shared public key that is used by encryption and hash algorithms. DH algorithms allow two parties to establish a shared secret key that is used by encryption and hash algorithms. Which two algorithms use Hash-based Message Authentication Code for message authentication? (Choose two.) SHA 3DES DES MD5 AES SHA MD5 What is an advantage of using the Cisco Secure Mobility Clientless SSL VPN? Any device can connect to the network without authentication. Security is provided by prohibiting network access through a browser. Clients use SSH to access network resources. Clients do not require special software. Clients do not require special software. Two corporations have just completed a merger. The network engineer has been asked to connect the two corporate networks without the expense of leased lines. Which solution would be the most cost effective method of providing a proper and secure connection between the two corporate networks? Frame Relay Cisco Secure Mobility Clientless SSL VPN Cisco AnyConnect Secure Mobility Client with SSL site-to-site VPN remote access VPN using IPsec site-to-site VPN Which algorithm is an asymmetrical key cryptosystem? AES RSA 3DES DES RSA Which service of IPsec verifies that secure connections are formed with the intended sources of data? data integrity authentication encryption confidentiality authentication
