Question 1

SSH can even be used as a tool for secure network backups.

Accepted Answer

SSH can be used to create secure backups by transferring data over an encrypted connection between the source and destination servers. This helps to ensure that sensitive data is protected during the backup process.

Question 2

In a ____ VPN, multiple sites can connect to other sites over the Internet.&#10;A) point-to-point&#10;B) person-to-person&#10;C) remote-access&#10;D) site-to-site

Accepted Answer

The described VPN scenario is site-to-site, also known as a LAN-to-LAN VPN. It allows multiple sites (local area networks) to securely connect with each other over the Internet. This type of VPN is commonly used in businesses that have multiple locations and need to share data and resources.

Question 3

____ is a set of protocols developed to support the secure exchange of packets.&#10;A) IPsec&#10;B) UDP&#10;C) HTTP&#10;D) FTP

Accepted Answer

IPsec (Internet Protocol Security) is the set of protocols developed specifically to support the secure exchange of packets. It provides confidentiality, integrity, and authentication to the data exchange between computers. UDP, HTTP, and FTP are protocols, but they do not offer the same level of security as IPsec.

Question 4

The ____ is a protocol used to manage networked equipment.&#10;A) PPTP&#10;B) SNMP&#10;C) FTP&#10;D) L2TP

Accepted Answer

SNMP (Simple Network Management Protocol) is specifically designed to manage and monitor networked devices such as routers, switches, and servers. PPTP (Point-to-Point Tunneling Protocol) and L2TP (Layer 2 Tunneling Protocol) are tunneling protocols for secure communication, and FTP (File Transfer Protocol) is used for transferring files between computers on a network.

Question 5

____ key cryptography uses a single key to both encrypt and decrypt the document.&#10;A) User&#10;B) Private&#10;C) Public&#10;D) Known

Accepted Answer

Private key cryptography, also known as symmetric cryptography, uses a single key for both encryption and decryption.

Question 6

A ____ VPN is a user-to-LAN connection used by remote users.&#10;A) site-to-multipoint&#10;B) site-to-site&#10;C) remote-access&#10;D) multipoint-to-multipoint

Accepted Answer

A remote-access VPN is used by individual users to securely connect to a private network from a remote location. In contrast, a site-to-site VPN connects entire networks, while a site-to-multipoint VPN connects one site to multiple other sites. A multipoint-to-multipoint VPN connects multiple sites together, allowing them to communicate with each other.

Question 7

____ is software that works with a computer's network interface card adapter to simulate a dial-up session and can assign IP addresses as necessary.&#10;A) LCP&#10;B) PPPoE&#10;C) L2TP&#10;D) IPsec

Accepted Answer

PPPoE (Point-to-Point Protocol over Ethernet) is software that can simulate a dial-up session and assign IP addresses as needed. It is commonly used by Internet Service Providers for broadband connections. LCP (Link Control Protocol) is used to establish and configure the PPP connection, but it does not assign IP addresses. L2TP (Layer 2 Tunneling Protocol) is used for creating virtual private networks (VPNs) but does not simulate a dial-up session. IPsec (Internet Protocol Security) is used for securing network traffic and does not simulate a dial-up session or assign IP addresses.

Question 8

L2TP is only supported by Windows 2000 versions and higher.

Accepted Answer

L2TP was first introduced in Windows 2000 and has been supported in all subsequent versions of Windows. It is not supported on Windows 95, 98, or ME.

Question 9

Cisco is probably the best-known hardware-based VPN and many of their routers are designed specifically for VPNs.

Accepted Answer

Cisco is indeed well-known for their hardware-based VPN solutions and many of their routers are built with VPN capabilities in mind.

Question 10

The ____ ensures that a connection is private by using data encryption; it also ensures that the connection is reliable.&#10;A) TLS Record Protocol&#10;B) Secure FTP&#10;C) TLS Handshake Protocol&#10;D) HTTP

Accepted Answer

The TLS Record Protocol is responsible for ensuring that the data exchanged between two systems is private and secure using encryption. It also ensures that the connection remains reliable by performing error detection and correction. The other options listed (Secure FTP, TLS Handshake Protocol, HTTP) do not provide the same level of security and reliability as the TLS Record Protocol.
