CISSP®- The (ISC)2 Code of Ethics

The video tutorial covers various networking protocols, starting with storage protocols like SAN and FCoE, explaining their use and benefits. It then delves into virtual storage area networks (VSANs) and their similarities to VLANs. The tutorial also discusses Voice over IP (VoIP), highlighting its advantages and the importance of low latency. Finally, it introduces Software Defined Networking (SDN), explaining its dynamic control over network behavior and its benefits.

What is the primary advantage of using Fibre Channel over Ethernet (FCoE) in a data center?

• It allows for routing across different data centers.

• It provides a cost-effective way to connect servers to external storage.

• It uses copper cables for faster data transmission.

• It eliminates the need for network infrastructure.

How do Virtual Storage Area Networks (VSANs) differ from traditional SANs?

• VSANs use copper cables instead of fiber.

• VSANs do not require any network infrastructure.

• VSANs are only used in different data centers.

• VSANs segment network ports like VLANs.

What is a key feature of iSCSI in network storage?

• It is not compatible with existing network infrastructure.

• It requires additional hardware for implementation.

• It uses Logical Unit Numbers (LUNs) for addressing.

• It only works with analog phones.

Why is UDP preferred over TCP for Voice over IP (VoIP) transmissions?

• UDP allows for real-time data transmission.

• UDP is connection-oriented and reliable.

• UDP requires less bandwidth than TCP.

• UDP ensures data packets arrive in order.

What is a major benefit of implementing VoIP in modern organizations?

• It requires no internet connection.

• It is more expensive than traditional phone systems.

• It is easier to manage and implement.

• It eliminates the need for power sources.

Which protocol is commonly associated with initiating VoIP sessions?

• SIP

• FCI

• RTP

• MGCP

What is a defining characteristic of Software Defined Networking (SDN)?

• It requires proprietary hardware.

• It relies solely on hardware for routing decisions.

• It separates the control plane from the data plane.

• It is limited to local area networks.

How does VXLAN enhance traditional VLAN capabilities?

• It reduces the number of available VLANs.

• It restricts VLANs to local entities only.

• It eliminates the need for encapsulation protocols.

• It allows VLANs to span across subnets and distant locations.

What is the role of SD-WAN in a network?

• It eliminates the need for software-defined solutions.

• It restricts network access to local users.

• It provides power to network devices.

• It connects data centers and cloud services over WAN links.

What is a potential risk associated with software-defined solutions like SDN?

• They are more expensive to implement.

• They require specific hardware vendors.

• They may introduce security vulnerabilities.

• They are harder to manage and control.
