1.6.6 Check Your Understanding – Reliable Networks
1. When designers follow accepted standards and protocols, which of the four basic characteristics of network architecture is achieved?
- fault tolerance
- Scalability
- QoS
- Security
Explanation: Scalability happens when designers follow accepted standards and protocols.
2. Confidentiality, integrity, and availability are requirements of which of the four basic characteristics of network architecture?
- fault tolerance
- Scalability
- QoS
- Security
Explanation: Confidentiality, integrity, and availability are requirements of security.
3. With which type of policy, a router can manage the flow of data and voice traffic, giving priority to voice communications if the network experiences congestion?
- fault tolerance
- Scalability
- QoS
- Security
Explanation: QoS means that a router will manage the flow of data and voice traffic, giving priority to voice communications.
4. Having multiple paths to a destination is known as redundancy. This is an example of which characteristic of network architecture?
- fault tolerance
- Scalability
- QoS
- Security
Explanation: Redundancy is an example a fault-tolerant network architecture.
