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.
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.
What is the main security benefit of using NAT in a network infrastructure?
- It automatically detects and blocks malicious traffic.
- It hides internal IP addresses from external networks.
- It implements strong access control policies.
- It provides encryption for all transmitted data.
The main security benefit of using NAT is that it hides internal IP addresses from external networks, adding a layer of security by obscuring the internal network structure.
What is the primary function of a router in a network?
- Connecting devices within the same network
- Filtering spam emails
- Forwarding data between different networks
- Managing Wi-Fi connections
The primary function of a router is to forward data between different networks, facilitating communication between them.
In advanced network management, how does SDN (Software-Defined Networking) change the approach to device monitoring?
- Centralized Control
- Decentralized Monitoring
- Static Configuration
- Traditional SNMP Monitoring
SDN changes the approach to device monitoring in advanced network management by introducing centralized control, allowing for dynamic and programmable monitoring strategies.
An organization wants to block all incoming traffic from a specific IP range due to security concerns. Which feature of ACLs would be most effective?
- Dynamic ACL
- Named ACL
- Reflexive ACL
- Standard ACL
Standard ACLs can filter traffic based on source IP addresses, making them effective for blocking specific IP ranges.
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.
