In a mesh topology, what method is typically used to ensure data reaches its destination via the most efficient route?
- Broadcasting
- Multicasting
- Routing
- Switching
In a mesh topology, routing is typically used to ensure data reaches its destination via the most efficient route. Routing algorithms determine the optimal path for data transmission.
What mechanism does BGP use to ensure that route updates are received and processed correctly?
- TCP
- MD5 Authentication
- TTL Security
- Prefix Lists
BGP uses the TCP (Transmission Control Protocol) to ensure that route updates are received and processed correctly.
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.
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.
