In troubleshooting, what is the significance of establishing a baseline performance measure?
- It helps to identify the root cause of the issue
- It provides a reference point for normal network behavior
- It speeds up the troubleshooting process
- It is not relevant in troubleshooting
Establishing a baseline performance measure is significant because it provides a reference point for normal network behavior, making it easier to identify deviations and potential issues.
In a QoS-enabled network, what is the purpose of implementing Traffic Shaping?
- Traffic Shaping is used to limit the rate of outgoing traffic to prevent network congestion and maintain a steady flow of data.
- Traffic Shaping increases the priority of critical traffic, ensuring faster delivery.
- Traffic Shaping is primarily used to block unwanted traffic from entering the network.
- In a QoS-enabled network, Traffic Shaping is not a relevant concept.
Traffic Shaping is implemented to control the rate of outgoing traffic, preventing network congestion and maintaining a steady flow of data.
How does BGP prevent routing loops in inter-domain routing?
- Split Horizon
- Route Poisoning
- Route Aggregation
- AS_PATH
In BGP, the AS_PATH attribute is used to prevent routing loops in inter-domain routing by tracking the path that the route has traversed.
In what scenario would static routing be more secure compared to dynamic routing?
- Dynamic routing is always more secure than static routing.
- In a scenario where the network topology is stable and predictable, static routing can be more secure than dynamic routing.
- Security is not a consideration in routing protocols.
- Static routing is always more secure than dynamic routing.
In scenarios with a stable and predictable network topology, static routing can be more secure as it reduces the attack surface by not dynamically exchanging routing information.
The process of modifying the characteristics of a traffic flow is known as _________ in QoS.
- Queuing
- Dropping
- Shaping
- Policing
Shaping in QoS refers to the process of modifying the characteristics of a traffic flow.
What is a major advantage of using automated configuration management tools like Ansible or Puppet in network device management?
- Faster Deployment
- Increased Security
- Enhanced Scalability
- Improved Troubleshooting
Automated configuration management tools like Ansible or Puppet enable faster deployment of configurations, reducing manual errors and ensuring consistency.
Which NAT configuration allows incoming connections initiated from the outside network to specific internal hosts?
- Dynamic NAT
- NAPT (Network Address Port Translation)
- Port Forwarding
- Static NAT
Static NAT allows incoming connections initiated from the outside network to specific internal hosts by mapping a public IP address to a private IP address.
A network administrator needs to configure a router to allow multiple devices in the internal network to access the internet using a single public IP address. Which technology should be used?
- Dynamic NAT
- NAT Overload
- PAT
- Static NAT
PAT (Port Address Translation) should be used when a router needs to allow multiple devices in the internal network to access the internet using a single public IP address.
The ________ header in IPv6 is used to ensure efficient routing and handling of packets.
- Fragment
- Hop-by-Hop Options
- Routing
- Extension
The Hop-by-Hop Options header in IPv6 is used to ensure efficient routing and handling of packets.
How does a VLAN Trunking Protocol (VTP) assist in managing VLANs across multiple switches?
- It allows switches to negotiate VLAN information
- It assigns VLANs dynamically
- It encrypts VLAN information
- It limits the number of VLANs per switch
VTP assists in managing VLANs across multiple switches by allowing switches to negotiate VLAN information automatically.
