22
Q

The higher the ______________ of 5G, the faster the possible throughput speeds and the shorter the range?

A

23
Q

The first generation DSL providers used a _____________ connection; once the DLS line was running, it was as if you had snapped an Ethernet cable into your NIC?

A

bridged

24
Q

The original idea for MPLS was to give individual ISPs a way to move traffic through their morass of different interconnections and _____________?

A

switches

25
Q

By 1987, the Primary Fiber-Optic Cable carriers settled on a single international standard called _______________ in Europe for handling the interconnections of long-distance Internet routers?

A

Synchronous Digital Hierarchy (SDH)

26
Q

An inexpensive way to connect to the Internet is through the purchase of dedicated connections - leased lines - from telecommunication companies?

True
False

A

False

27
Q

One nice aspect of DSL is that you do not have to run new phone lines?

True
False

A

True

28
Q

The GSM Standard was considered a 5G Technology?

True
False

A

False

29
Q

On the Windows client side of a PPTP VPN connection, where does a client get an IP Address from after it creates a Virtual NIC?

PPP Private Connection
DHCP Server
Default Gateway
WINS Server

A

DHCP Server

30
Q

MPLS-capable Routers avoid running IP Packets through their full routing tables and instead use the header information to route packets quickly?

True
False

A

True

31
Q

SONET remains an important standard for long-distance, high-speed, fiber-optic transmission systems?

True
False

A

True

32
Q

Which standard, developed by Citrix, defined how terminal information was passed between the Server and the Client?

RDP
SIP
RDC
ICA

A

ICA (Independent Computing Architecture)

Explanation:
RDP = Remote Desktop Protocol (Microsoft)
RDC = Remote Desktop Connection (Microsoft)

33
Q

A common early DSL installation consisted of a _______________ connected to a telephone wall jack and to a standard network interface card NIC in the computer?

Router
multiplexer
CSU/DSU
DSL Modem

A

DSL Modem

34
Q

What are the two most common types of SSL VPNs?

SSL Tunnel VPNs and IPsec Tunnel VPNs
TLS Portal VPNs and SSL Tunnel VPNs
IPsec Tunnel VPNs and TLS Portal VPNs
SSL Portal VPNs and SSL Tunnel VPNs

A

SSL Portal VPNs and SSL Tunnel VPNs

35
Q

Which proprietary CISCO Protocol was combined with PPTO to create the Layer 2 Tunneling Protocol (L2TP)?

CGMP
EIGRP
L2F
CDP

A

L2F

36
Q

Describe SSL Portal VPNs?

A

Clients access the VPN and is presented with a Secure Web Page (Portal).
The Client gains access to anything linked on that Portal Page.

37
Q

Describe how a single client might connect to a Cisco L2TP VPN?

A

Free Client software that creates a typical Host-to-Site or Client-to-Site Connection.

38
Q

How does L2TP differ from PPTP in terms of Security?

A

L2TP has no authentication or encryption and uses IPsec for all Security needs.
PPTP creates a Secure Tunnel through the Internet to a Private LAN, where the Client takes on an IP Address of that Network as if your computer is directly connected to the LAN at the Office.

39
Q

Explain the term “Smart Jack”?

A

It’s a NIU (Network Interface Unit) that enables loopback testing so that the ISP can remotely check your line and box.

40
Q

Describe SSL VPNs?

A

SSL VPNs don’t require any special Client Software, known as Clientless VPN, the connection is handled through a standard Web Browser using TLS or SSL Security.

SONET

44
Q

SONET

A

PSTN (Public Switched Telephone Network)

48
Q

In designing PPTP, where does Microsoft place the two endpoints of a VPN?

A

Client and the Server = Point-to-Point

49
Q

Discuss the current status and capability of Long Term Evolution (LTE) technology?

A

They were rolled out around 2010 and now dominate Wireless Services.
Speeds up to 300 Mbps Download and 75 Mbps Upload.

50
Q

Briefly describe a Passive Optical Network (PON) Architecture?

A

Uses a single fiber to the neighborhoods Switch and then individual fiber runs to each final destination.
Uses WDM to enable multiple signals to travel on the same fiber and then Passively splits the signal at the switch to send traffic to its proper recipient.

51
Q

Briefly describe the third-party terminal emulation program called VNC?
