CISSP®- Third-Party Acquisitions and Divestiture Security

The video tutorial covers the structure of the Internet, focusing on legacy and modern network connections and protocols. It explains the roles of T1, E1, Frame Relay, X.25, SONET, and MPLS in networking. The tutorial also discusses data link control protocols like SDLC and HDLC, and the use of DNP3 in SCADA systems for automation in utilities.

What is the primary role of Internet Service Providers (ISPs) in the structure of the Internet?

• To manage domain names

• To host websites

• To connect local networks to the global Internet

• To provide email services

Which of the following is a characteristic of Frame Relay?

• It is primarily used for voice communication

• It is a layer 3 protocol

• It uses permanent virtual circuits

• It provides error correction

What is the primary function of DLCIs in Frame Relay?

• To identify virtual connections

• To provide error correction

• To encrypt data

• To manage bandwidth allocation

What is a key advantage of MPLS over traditional IP routing?

• It is limited to fiber optic networks

• It can create end-to-end circuits across different media

• It uses IP addresses for routing

• It requires less configuration than Ethernet

Which of the following is NOT a legacy connection?

• X.25

• MPLS

• E3

• T1

Which protocol is known for its use in SCADA systems for communication?

• Frame Relay

• MPLS

• DNP3

• HDLC

What is the main difference between SDLC and HDLC?

• HDLC is a legacy protocol, SDLC is not

• SDLC supports error correction, HDLC does not

• HDLC supports error correction and flow control, SDLC does not

• SDLC is used for SCADA systems, HDLC is not
