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.
Employing _________ during troubleshooting ensures a comprehensive understanding of the problem from higher to lower layers of the network.
- Ping
- Traceroute
- SNMP
- Wireshark
Employing Wireshark during troubleshooting provides a comprehensive understanding of the problem by capturing and analyzing traffic from higher to lower layers of the network.
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.
