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.

In an organization looking to scale its network infrastructure with minimal physical changes, which SDN capability would be most critical?

  • Network Function Virtualization (NFV)
  • Southbound API
  • Northbound API
  • Control Plane Separation
Network Function Virtualization (NFV) in SDN allows scaling the network infrastructure by virtualizing network functions, minimizing the need for physical changes.

In a stacked configuration, individual switches are interconnected using a ________ link.

  • Backbone
  • Mesh
  • Trunk
  • Uplink
In a stacked configuration, individual switches are interconnected using a trunk link to facilitate communication and coordination.

How does GRE tunneling differ from traditional VPN tunneling in terms of encryption and security features?

  • GRE focuses on providing a simple encapsulation method without inherent encryption.
  • GRE offers stronger encryption and security features compared to traditional VPNs.
  • GRE and traditional VPNs have identical encryption and security features.
  • GRE and traditional VPNs do not support encryption.
GRE primarily provides encapsulation and does not inherently offer encryption, unlike traditional VPNs that focus on security features.

________ encryption is commonly used in SSH for securing remote management sessions.

  • Symmetric
  • Asymmetric
  • Public Key
  • Private Key
Asymmetric encryption is commonly used in SSH for securing remote management sessions.

What is the primary purpose of the Spanning Tree Protocol (STP) in a network?

  • Error detection
  • Load balancing
  • Preventing loops
  • Reducing latency
The primary purpose of the Spanning Tree Protocol (STP) is to prevent loops in a network topology, ensuring a loop-free and stable network.

In DHCP, what is the purpose of the lease time?

  • To specify the client's hardware address
  • To determine the subnet mask
  • To define the period a client can use an IP address
  • To assign a default gateway
The lease time in DHCP defines the period during which a client can use the assigned IP address before renewal is required.
