New headers from one or more VPN protocols encapsulate the original packets.

How is "tunneling" accomplished in a VPN? -New headers from one or more VPN protocols encapsulate the original packets. -All packets between two hosts are assigned to a single physical medium to ensure that the packets are kept private. -Packets are disguised to look like other types of traffic so that they will be ignored by potential attackers. -A dedicated circuit is established between the source and destination devices for the duration of the connection.

209.165.200.225

Refer to the exhibit. Which source address is being used by router R1 for packets being forwarded to the Internet? -10.6.15.2 -209.165.202.141 -198.51.100.3 -209.165.200.225

clientless SSL

Which VPN solution allows the use of a web browser to establish a secure, remote-access VPN tunnel to the ASA? -client-based SSL -site-to-site using an ACL -clientless SSL -site-to-site using a preshared key

when its employees become distributed across many branch locations

Which circumstance would result in an enterprise deciding to implement a corporate WAN? -when the enterprise decides to secure its corporate LAN -when its employees become distributed across many branch locations -when the number of employees exceeds the capacity of the LAN -when the network will span multiple buildings

It requires a VPN gateway at each end of the tunnel to encrypt and decrypt traffic.

Which is a requirement of a site-to-site VPN? -It requires hosts to use VPN client software to encapsulate traffic. -It requires the placement of a VPN server at the edge of the company network. -It requires a VPN gateway at each end of the tunnel to encrypt and decrypt traffic. -It requires a client/server architecture.

Employees need to connect to the corporate email server through a VPN while traveling.

Which network scenario will require the use of a WAN? -Employees need to connect to the corporate email server through a VPN while traveling. -Employees need to access web pages that are hosted on the corporate web servers in the DMZ within their building. -Employee workstations need to obtain dynamically assigned IP addresses. -Employees in the branch office need to share files with the headquarters office that is located in a separate building on the same campus network.

An employee shares a database file with a co-worker who is located in a branch office on the other side of the city.

Which situation describes data transmissions over a WAN connection? -A network administrator in the office remotely accesses a web server that is located in the data center at the edge of the campus. -A manager sends an email to all employees in the department with offices that are located in several buildings. -An employee prints a file through a networked printer that is located in another building. -An employee shares a database file with a co-worker who is located in a branch office on the other side of the city.

VPNs use virtual connections to create a private network through a public network.

Which statement describes a VPN? -VPNs use open source virtualization software to create the tunnel through the Internet. -VPNs use logical connections to create public networks through the Internet. -VPNs use dedicated physical connections to transfer data between remote users. -VPNs use virtual connections to create a private network through a public network.

It must be statically set up.

Which statement describes an important characteristic of a site-to-site VPN? -It must be statically set up. -It is ideally suited for use by mobile workers. -It requires using a VPN client on the host PC. -After the initial connection is established, it can dynamically change connection information. -It is commonly implemented over dialup and cable modem networks.
