In a high-traffic network environment, a network engineer is tasked with improving bandwidth and redundancy. Which approach would they most likely consider?
- Load Balancing
- Quality of Service (QoS)
- Subnetting
- VLAN Segmentation
The network engineer would most likely consider implementing load balancing to improve bandwidth and redundancy in a high-traffic environment. Load balancing distributes network traffic across multiple paths, optimizing resource utilization.
What protocol is used by switches to prevent loops in a network with redundant paths?
- BGP (Border Gateway Protocol)
- OSPF (Open Shortest Path First)
- RIP (Routing Information Protocol)
- STP (Spanning Tree Protocol)
Switches use the Spanning Tree Protocol (STP) to prevent loops in a network with redundant paths. STP helps in blocking redundant paths and ensuring a loop-free topology.
In switch configuration, what is the purpose of setting up VLANs?
- To enhance switch security
- To increase network speed
- To segment a network into smaller, isolated broadcast domains
- To simplify network management
Setting up VLANs in switch configuration allows for the segmentation of a network into smaller, isolated broadcast domains. This enhances network performance and security by controlling broadcast traffic.
In STP, what is the role of the designated port in each network segment?
- Blocking Port
- Forwarding Port
- Learning Port
- Listening Port
The designated port in each network segment is the one that is in the Forwarding state, responsible for actively passing data frames in the segment.
What is a key advantage of using chassis aggregation in terms of network management?
- Faster data transfer
- Improved scalability
- Lower cost
- Reduced power consumption
Chassis aggregation provides improved scalability in terms of adding more ports or capacity, enhancing network management capabilities.
What is the purpose of the STP port states like blocking, listening, learning, and forwarding?
- Enhance Security
- Prevent Loops
- Prioritize Voice Traffic
- Speed Up Data Transmission
STP port states serve to prevent loops in the network. Blocking, listening, learning, and forwarding are stages in the convergence process to ensure a loop-free topology.
What is the significance of configuring zone-based firewalls in complex network environments?
- Zone-based firewalls provide a flexible and granular approach to defining security policies between network zones
- Zone-based firewalls are only suitable for small-scale networks and may not be effective in complex environments
- Configuring zone-based firewalls is unnecessary in complex network environments
- Zone-based firewalls only support stateless packet filtering, limiting their effectiveness
Configuring zone-based firewalls in complex network environments is significant because it provides a flexible and granular approach to defining security policies between different network zones.
To enhance security, Port Security settings can be made persistent across reboots by saving them in the ________.
- Flash Memory
- NVRAM
- Running Configuration
- Startup Configuration
Port Security settings can be saved in the startup configuration to make them persistent across reboots.
For dynamic EtherChannel configuration, _______ is typically used in a Cisco environment, while _______ is a standard protocol supported by multiple vendors.
- GLBP, HSRP
- HSRP, GLBP
- LACP, PAgP
- PAgP, LACP
For dynamic EtherChannel configuration, LACP (Link Aggregation Control Protocol) is typically used in a Cisco environment, while PAgP (Port Aggregation Protocol) is a standard protocol supported by multiple vendors.
A subnet mask of 255.255.255.192 indicates a ________ subnet size.
- Large
- Medium
- Small
- Variable
A subnet mask of 255.255.255.192 indicates a medium-sized subnet.
