A company with several branches across the country needs a reliable, high-speed connection for data and voice traffic. Which WAN technology should they consider?
- MPLS
- DSL
- Satellite
- Frame Relay
MPLS (Multiprotocol Label Switching) is a reliable and high-speed WAN technology suitable for connecting multiple branches and handling data and voice traffic efficiently.
Which STP component is responsible for preventing loops by blocking redundant paths in a network topology?
- Blocking Port
- Designated Port
- Non-Designated Port
- Root Bridge
The blocking port is responsible for preventing loops by blocking redundant paths in a network topology, as part of the Spanning Tree Protocol (STP).
The _______ layer of the OSI model is responsible for the physical connection between devices.
- Data Link
- Network
- Physical
- Transport
The physical layer of the OSI model is responsible for the physical connection between devices.
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.

- Large
- Medium
- Small
- Variable
A subnet mask of 255.255.255.192 indicates a medium-sized subnet.
What WAN technology is characterized by its ability to provide a scalable and efficient VPN solution?
- MPLS
- Frame Relay
- DSL
- ISDN
MPLS (Multiprotocol Label Switching) is characterized by its ability to provide a scalable and efficient VPN (Virtual Private Network) solution.
GRE tunnels can carry both IPv4 and IPv6 traffic, making them suitable for _______ environments.
- Virtual Private Networks (VPNs)
- Mixed Protocol
- Multiprotocol
- Dual Stack
GRE tunnels can carry both IPv4 and IPv6 traffic, making them suitable for multiprotocol environments.
How does EtherChannel affect the spanning-tree topology in a network?
- It creates a loop-free redundant path
- It eliminates the need for spanning tree
- It improves convergence time
- It introduces network latency
EtherChannel affects the spanning-tree topology by creating a loop-free redundant path, enhancing network redundancy and reliability.
