The use of ______ routing in a highly dynamic environment can lead to increased administrative overhead and potential network issues.
- Adaptive
- Convergent
- Dynamic
- Static
The use of static routing in a highly dynamic environment can lead to increased administrative overhead and potential network issues.
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.
________ is a common issue in BGP networks caused by incorrect route advertisement.
- Route Flap
- Prefix Deaggregation
- Route Divergence
- Route Oscillation
Route Divergence is a common issue in BGP networks caused by incorrect route advertisement.
