What is the primary purpose of subnetting in IP networking?
- Enhance network security
- Improve network performance
- Increase the number of available host addresses
- Simplify IP address management
The primary purpose of subnetting is to increase the number of available host addresses within a network.
A network engineer is designing a network for a small company. They need a simple, cost-effective topology that is easy to set up and manage. Which topology should they consider?
- Bus
- Mesh
- Ring
- Star
For a small company with the need for a simple, cost-effective topology that is easy to set up and manage, a star topology is suitable.
In AAA security, what does Authorization specifically control?
- Authentication
- Access
- Accounting
- Addressing
In AAA security, Authorization specifically controls access, determining what resources a user is allowed to access after successful authentication.
What is the first step typically taken in a systematic approach to network troubleshooting?
- Identify the problem
- Implement the solution
- Document the findings
- Verify the solution
The first step in a systematic approach to network troubleshooting is to identify the problem, which involves understanding and defining the issue at hand.
A _________ is a set of rules applied to a router to control network traffic and mitigate security risks.
- Firewall
- Protocol
- Routing Table
- Access Control List (ACL)
An Access Control List (ACL) is a set of rules applied to a router to control network traffic and mitigate security risks.
How does serverless computing differ from traditional cloud computing models?
- Serverless computing abstracts server management entirely, and users only pay for actual usage
- Serverless computing relies on physical servers for resource allocation
- Traditional cloud computing models are event-driven, while serverless models are request-driven
- Serverless computing uses virtualization technology exclusively
Serverless computing differs from traditional cloud computing by abstracting server management entirely, and users only pay for actual usage, eliminating the need for provisioning and managing servers.
In complex network environments, why is it crucial to document and analyze network change logs during troubleshooting?
- Change logs provide a historical record of network configurations and changes
- Change logs are unnecessary and can be ignored during troubleshooting
- Analyzing change logs only helps in identifying minor issues
- Change logs are useful only for auditing purposes
Documenting and analyzing network change logs in complex environments is crucial as they provide a historical record of network configurations and changes, aiding in identifying potential causes of issues.
What is the purpose of subnetting in IPv4 networks?
- To improve network security
- To increase the number of available IP addresses
- To provide a way to group hosts logically and efficiently
- To reduce network congestion
Subnetting in IPv4 networks serves the purpose of logically grouping hosts to optimize network management and improve efficiency.
How does route summarization impact the convergence time in a dynamic routing environment?
- Accelerates convergence
- Delays convergence
- Has no impact on convergence
- Improves route computation
Route summarization can potentially delay convergence in a dynamic routing environment by limiting the exchange of detailed route information between routers.
What is the primary function of Border Gateway Protocol (BGP) in networking?
- Dynamic Routing
- Interior Gateway Protocol (IGP)
- Exterior Gateway Protocol (EGP)
- Link-State Routing
The primary function of Border Gateway Protocol (BGP) is to exchange routing information between different Autonomous Systems (AS) on the Internet, making it an Exterior Gateway Protocol (EGP).
