  2. Network optimization

  3. Traffic engineering

  4. Load balancing

  5. All of the above
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

To address network capacity constraints, various strategies can be employed, including network expansion, optimization, traffic engineering, and load balancing, aiming to increase capacity, improve efficiency, and optimize resource utilization.

Multiple choice

Which of the following is NOT a common strategy for achieving network resiliency?

  1. Redundancy

  2. Diversity

  3. Isolation

  4. Centralization
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Centralization involves concentrating network resources and services in a single location, which can increase the risk of a single point of failure. Redundancy, diversity, and isolation are all strategies for distributing and isolating network components to improve resiliency.

Multiple choice

Which of the following is an example of network diversity?

  1. Using different types of network media, such as fiber optic and copper.

  2. Connecting to multiple Internet service providers.

  3. Using different routing protocols.

  4. Implementing network segmentation.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Network diversity involves using different network paths, technologies, or providers to reduce the impact of a single point of failure. Connecting to multiple Internet service providers is an example of diversity because it provides multiple paths for traffic to reach its destination.

Multiple choice

Which of the following is a common metric used to measure network resiliency?

  1. Mean time to failure (MTTF)

  2. Mean time to repair (MTTR)

  3. Availability

  4. Throughput
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Availability is a common metric used to measure network resiliency. It represents the percentage of time that a network is operational and accessible to users.

Multiple choice

What is the concept of graceful degradation in the context of network resiliency?

  1. The ability of a network to continue operating at a reduced capacity in the event of a failure.

  2. The process of gradually shutting down a network to minimize the impact of a failure.

  3. The ability of a network to recover quickly from a failure without data loss.

  4. The ability of a network to prevent failures from occurring in the first place.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Graceful degradation is the ability of a network to continue operating at a reduced capacity in the event of a failure. This allows critical services to remain available even when some parts of the network are experiencing problems.

Multiple choice

Which of the following is an example of a network resiliency technology?

  1. Software-defined networking (SDN)

  2. Network virtualization

  3. Load balancing

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Software-defined networking (SDN), network virtualization, and load balancing are all examples of network resiliency technologies. SDN provides flexibility and programmability, network virtualization allows for the creation of isolated network segments, and load balancing distributes traffic across multiple paths to improve performance and reliability.

Multiple choice

Which networking model is commonly used in multiplayer games to facilitate communication between players?

  1. Client-Server Model

  2. Peer-to-Peer Model

  3. Hybrid Model

  4. Distributed Model
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Client-Server Model is widely used in multiplayer games, where one central server manages the game state and communicates with individual clients (players) to synchronize information and actions.
