How does Dynamic ARP Inspection (DAI) work in conjunction with DHCP Snooping to enhance network security?
- Enforcing DHCP lease time
- Filtering broadcast ARP requests
- Inspecting DHCP transactions
- Validating ARP packets
Dynamic ARP Inspection (DAI) works by inspecting DHCP transactions, validating ARP packets, and ensuring that only valid ARP responses are forwarded, enhancing network security.
A company is expanding its network and needs to create multiple subnets for different departments without wasting IP addresses. Which subnetting strategy should they use?
- CIDR (Classless Inter-Domain Routing)
- Classful Subnetting
- Supernetting
- Variable Length Subnet Masking (VLSM)
Variable Length Subnet Masking (VLSM) allows the creation of multiple subnets with different sizes, efficiently using IP addresses for different departments.
Which scripting language is commonly used for basic network automation tasks due to its simplicity and readability?
- Java
- Python
- C++
- Ruby
Python is commonly used for basic network automation tasks due to its simplicity and readability.
_____ routing can lead to suboptimal routing decisions if the network topology changes and the routes are not updated manually.
- Default
- Dynamic
- Hybrid
- Static
Static routing can lead to suboptimal routing decisions if the network topology changes and the routes are not updated manually.
In a scenario where specific types of traffic must be monitored and controlled, a network administrator would implement ________ ACLs.
- Dynamic
- Extended
- Named
- Standard
In scenarios where specific types of traffic must be monitored and controlled, network administrators would implement Extended ACLs, which are more specific and versatile.
How does Infrastructure as Code (IaC) contribute to network automation?
- It provides a graphical user interface for network configuration
- It enables manual configuration of devices
- It allows defining and managing network infrastructure through code
- It automates network monitoring tasks
Infrastructure as Code (IaC) allows the definition and management of network infrastructure through code, contributing to automation by eliminating manual configuration and ensuring consistency.
What is a common method used in QoS to manage network congestion and maintain data quality?
- Network encryption
- Traffic filtering
- Congestion avoidance
- Device authentication
Congestion avoidance is a common method used in QoS to manage network congestion and maintain data quality.
In a network transitioning from a legacy protocol to a more advanced routing protocol, the network engineer must ensure seamless communication between different parts of the network. What strategy should they employ?
- Quality of Service (QoS)
- Route Redistribution
- Route Summarization
- Virtual LANs (VLANs)
Route redistribution is the strategy to employ when transitioning from a legacy protocol to a more advanced routing protocol, ensuring seamless communication between different parts of the network by redistributing routes between routing protocols.
Which routing method is typically used in larger, more complex networks where frequently changing network information requires dynamic adjustments?
- Default Routing
- Dynamic Routing
- Hybrid Routing
- Static Routing
Dynamic routing is typically used in larger, more complex networks where frequently changing network information requires dynamic adjustments to routing tables.
_________ is crucial in large networks to prevent routing loops during the redistribution process.
- Route Authentication
- Route Encryption
- Route Filtering
- Route Tagging
Route filtering is crucial in large networks to prevent routing loops during the redistribution process. It involves controlling which routes are allowed or denied during the redistribution process.
