In a data center, the network team is implementing EtherChannel to enhance throughput and redundancy. What configuration aspects are critical to ensure optimal performance and reliability?
- DHCP configuration, broadcast storm control, and OSPF areas
- Duplex settings, access control lists, and SNMP versions
- Link aggregation mode, spanning-tree protocol parameters, and interface MTU
- NAT settings, VLAN pruning, and HSRP priorities
Configuring link aggregation mode, spanning-tree protocol parameters, and interface MTU are critical aspects for ensuring optimal performance and reliability when implementing EtherChannel in a data center.
Which protocol is commonly used for communication between the SDN controller and network devices?
- SNMP
- OSPF
- OpenFlow
- BGP
OpenFlow is a widely used protocol for communication between the SDN controller and network devices, enabling centralized control.
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.
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.
