What is a dedicated WAN?
Dedicated connections. Dedicated connections are point-to-point serial connections that offer fixed, permanent connections to remote networks. Dedicated links can provide up to T3 (44.736 Mbps) speeds over a public carrier’s network.

What are the WAN services?
A wide area network (WAN) is a telecommunications network that extends over a large geographic area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits.
What technology does WAN use?
Wired WANs usually consist of broadband internet services and multiprotocol label switching (MPLS), which is a form of data-forwarding technology used to control traffic flow and speed up connection, while wireless WANs normally include 4G/5G and Long-Term Evolution (LTE) networks.
Which technology provides security for data that is transmitted over the Internet?
Secure Sockets Layer (SSL) Protocol
SSL is supported by all currently available Web servers and Web browsers. It is also gaining acceptance for other protocols, including LDAP and IMAP. The SSL protocol provides authentication, data encryption, and data integrity, in a public key infrastructure (PKI).
Which WAN connectivity option is based on Ethernet LAN technology?
Ethernet Private Line – EPL
Like Metro Ethernet, Ethernet over Synchronous Optical Network (SONET) is the type of WAN technology used.
Which communication method is used in all WAN connections?
Communication medium used by WAN are PSTN or Satellite links. WAN operates on low data rates.
Which WAN technology uses a fixed payload of 48 bytes and is transported across both switched and permanent virtual circuits?
Which WAN technology uses a fixed payload of 48 bytes and is transported across both switched and permanent virtual circuits? Asynchronous Transfer Mode (ATM) cells are always a fixed length of 53 bytes that contain 48 bytes of ATM payload and a 5-byte ATM header.
Which technology should be implemented to ensure data confidentiality as data is transmitted?
Encryption is an important technology used to protect confidentiality.
What are the types of Internet security?
Types of Network Security Protections
- Firewall. Firewalls control incoming and outgoing traffic on networks, with predetermined security rules. …
- Network Segmentation. …
- Remote Access VPN. …
- Email Security. …
- Data Loss Prevention (DLP) …
- Intrusion Prevention Systems (IPS) …
- Sandboxing. …
- Hyperscale Network Security.
Which WAN infrastructure service is example of private connection?
Private WAN technologies include leased lines, dialup, ISDN, Frame Relay, ATM, Ethernet WAN (an example is MetroE), MPLS, and VSAT.
Which WAN technology is cell based and well suited to carry voice and video traffic?
ATM is cell-based architecture. The small and fixed cells are well-suited for carrying voice and video traffic because this traffic is intolerant of delay. Video and voice traffic do not have to wait for larger data packets to be transmitted. ISDN is circuit-switched.
Which two devices are commonly used as data communications equipment?
Typically, data communications equipment (DCE) refers to modems, Channel Service Unit/Data Service Units (CSU/DSUs), multiplexers, and similar devices. The purpose of a DCE is to provide termination for the telecommunications link and an interface for connecting data terminal equipment (DTE) to the link.
Which two WAN infrastructure services are examples of?
Which two WAN infrastructure services are examples of private connections? (Choose two.) Explanation: Private WANs can use T1/E1, T3/E3, PSTN, ISDN, Metro Ethernet, MPLS, Frame Relay, ATM, or VSAT technology.
Which of the following is an example of a public WAN?
A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive. The Internet is an example of a worldwide public WAN.
Which WAN term defines the point where the subscriber connects to the service providers network?
Demarcation Point – This is a point established in a building or complex to separate customer equipment from service provider equipment. Physically, the demarcation point is the cabling junction box, located on the customer premises, that connects the CPE wiring to the local loop.
What is a disadvantage of leased lines?
Disadvantages of using a leased line
Although pricing has decreased over time, the cost of installation, combined with the ongoing monthly rental fees of a leased line, remain significantly higher than that of other connection alternatives, such as ADSL or FTTC. It can be an expensive form of data connectivity.
What are the key WAN technology concepts?
A WAN is a network that uses various links—private lines, Multiprotocol Label Switching (MPLS), virtual private networks (VPNs), wireless (cellular), the Internet—to connect smaller metropolitan and campus networks in diverse locations into a single, distributed network.
Which technologies are suitable for WAN connections over 50 Mbps?
SDH also provides 50 Mbps bandwidth at STM – 0. DWDM: DWDM stands for Dense Wavelength and Division Multiplexing and is a type of optical technology which is majorly introduced to further increase the bandwidth over fiber optic to overcome the requirements.
