Remote Access and VPN Connectivity Flashcards
Which of the following is the standard that was defined by the industry so that users would not have to know the type of ISDN switch they are connected to in order to buy equipment?
ISDN-NI
NI
NI-1
NI-1
The National ISDN 1 (NI-1) standard was defined by the industry so that users would not have to know the type of switch to which they are connected in order to buy equipment and software compatible with it
How many B channels are available in a typical ISDN PRI?
2
20
23
23
PRI is intended for users with greater bandwidth requirements. It requires T1 carriers to facilitate communications. Normally, the channel structure contains 23 B channels plus one 64 Kbps D channel, for a total of 1536 Kbps
Which network-layer protocols can the Serial Line Internet Protocol use during a dial-up session?
TCP/IP
IPX/SPX
PPP
TCP/IP
The Serial Line Internet Protocol, or SLIP, is a communications protocol used for making a TCP/IP connection over a serial interface to a remote network. SLIP was designed for connecting to remote UNIX servers across a standard phone line. This protocol was one of the first of its kind, enabling a remote network connection to be established over a standard phone line
Which remote protocol supports running many different types of network protocols over a serial link?
SLIP
PPP
IPX
PPP
PPP established other standards, including asynchronous and bit-oriented synchronousencapsulation, network protocol multiplexing, session negotiation, and data-compression negotiation. PPP also supports protocols other than TCP/IP, such as IPX/SPX and DECnet
Which components are part of the Point-to-Point Protocol?
Network control protocol
Link Control Protocol
Internet Protocol
Internet Packet Exchange Protocol
Network control protocol
Link Control Protocol
PPP uses the High-Level Data-Link Control (HDLC) protocol as the basis to encapsulate its data during transmission; PPP uses the Link Control Protocol (LCP) to establish, test, and configure the data link connection; various network control protocols (NCPs) are used to configure the different communications protocols. This enables you to use different protocols, such as TCP/IP and IPX, over the same line simultaneously
Which network control protocol is used in PPP to facilitate the transport of TCP/IP?
IPNP
IPCP
IPXCP
IPCP
The Internet Protocol Control Protocol (IPCP) is the NCP used to configure, enable, and disable the IP protocol modules at each end of the link
Which forms of validation can PPP use to authenticate a remote server?
CHAP
Domain account
PAP
KPA
CHAP
PAP
With PPP, each system could be required to authenticate itself. This can be done using an authentication protocol. The most common authentication protocols include the Challenge Handshake Authentication Protocol (CHAP), the Password Authentication Protocol (PAP), and the Microsoft adaptation of CHAP, MS-CHAP
Where is the logging information for a connection appended when modem logging is enabled?
modemlog. txt
ppp. log
modemlog_modemname.txt
modemlog_modemname.txt
When logging has been enabled, you can see the log file after the next attempt to connect to a PPP server. The log file, modemlog_modemname.txt, is stored in the Windows directory by default. It can be viewed by any standard text editor and is appended to each time a new connection is attempted
Which Windows feature can create a dial-up connection in Windows?
Device Manager
Accessories
New Connection Wizard
New Connection Wizard
The New Connection Wizard found in your network connections window allows you to create new connections that connect to a RAS or VPN server
Which application programming interface is used to include features such as call monitoring and multiple localities?
Unimodem
COMM
TAPI
TAPI
TAPI also provides other features, such as multiple calling locations. You can set up different connection profiles for different dial-up access numbers. You can also customize how the number is dialed. For example, if you set up two separate connection profiles, one with call waiting enabled and the second without it, you can manage multiple connections without having to reconfigure your modem setup every time you need a variation
What technology do virtual private networks offer to provide a more secure communications channel?
IP header compression
Tunneling
Multiple network protocol support
Tunneling
PPTP tunneling is used in TCP/IP networks as an alternative to conventional dial-up networking methods. This enables multiprotocol secure communications over a public TCP/IP network such as the Internet. PPTP takes advantage of an additional level of security that is not currently available in other standard implementations
Which of the following are protocols used for VPN solutions?
PPTP
PPP
L2TP
SLIP
PPTP
L2TP
VPNs establish tunnels by using VPN protocols such as PPTP and L2TP
Which of the following is the process for setting up a “tunnel” for PPTP?
PPP connection and communication
PPTP control connection
PPTP data tunneling
PPTP control connection
When the PPP session is established, PPTP creates a control connection between the client and the remote PPTP server. This process is referred to as tunneling
