Which QoS mechanism is used to prioritize certain types of traffic over others?
- Weighted Fair Queuing (WFQ)
- First-Come, First-Served (FCFS)
- Last-In, First-Out (LIFO)
- Round Robin
Weighted Fair Queuing (WFQ) is a QoS mechanism used to prioritize certain types of traffic over others based on assigned weights.
_________ is a method in QoS that dynamically adjusts the priority of different traffic types based on network conditions.
- Policing
- Shaping
- Queuing
- Classification
In QoS, classification is a method that dynamically adjusts the priority of different traffic types based on network conditions.
In complex network environments, ________ is used to reduce the risk of VLAN hopping attacks.
- VLAN Access Control
- VLAN Pruning
- VLAN Segmentation
- VLAN Trunking
VLAN Access Control is used in complex network environments to reduce the risk of VLAN hopping attacks.
BGP uses the _______ attribute to identify the originating Autonomous System of a route.
- AS Path
- Origin
- Next Hop
- Local Preference
BGP uses the Origin attribute to identify the originating Autonomous System of a route.
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.
What feature should be enabled on network devices to secure access and track changes made by different users?
- VLANs
- Port Security
- SNMP
- AAA (Authentication, Authorization, and Accounting)
AAA (Authentication, Authorization, and Accounting) should be enabled on network devices to secure access and track changes made by different users.
Which WAN technology provides dedicated, high-bandwidth connectivity using fiber-optic cable?
- MPLS
- Frame Relay
- DSL
- SONET/SDH
SONET/SDH (Synchronous Optical Networking/Synchronous Digital Hierarchy) provides dedicated, high-bandwidth connectivity using fiber-optic cable.
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.
