Which routing protocol is used to exchange routing information between autonomous systems?
C
Correct answer
Explanation
BGP (Border Gateway Protocol) is used to exchange routing information between autonomous systems, enabling the internet to function as a single, interconnected network.
What is the primary function of a routing table in a network?
-
To store IP addresses
-
To manage network traffic
-
To determine the best path for data packets
-
To assign IP addresses to devices
C
Correct answer
Explanation
The routing table contains information about the available paths to different networks and helps determine the best route for data packets to reach their destination.
Which routing algorithm is known for its simplicity and is commonly used in small networks?
A
Correct answer
Explanation
RIP (Routing Information Protocol) is a simple and widely used routing algorithm that is commonly implemented in small networks due to its ease of configuration and maintenance.
Which routing protocol is designed specifically for large and complex networks?
B
Correct answer
Explanation
OSPF (Open Shortest Path First) is a routing protocol designed for large and complex networks, providing efficient routing and scalability.
What is the primary purpose of subnet masking in IP addressing?
-
To hide IP addresses
-
To improve network performance
-
To divide a network into smaller segments
-
To assign IP addresses to devices
C
Correct answer
Explanation
Subnet masking is used to divide a network into smaller segments, allowing for more efficient IP address management and improved network performance.
Which routing protocol is commonly used in enterprise networks and supports multiple routing metrics?
D
Correct answer
Explanation
EIGRP (Enhanced Interior Gateway Routing Protocol) is commonly used in enterprise networks and supports multiple routing metrics, providing flexibility and optimization in routing decisions.
What is the role of a routing metric in determining the best path for data packets?
-
To measure the distance between networks
-
To calculate the cost of a path
-
To determine the speed of a path
-
To assign IP addresses
B
Correct answer
Explanation
A routing metric is used to calculate the cost of a path, considering factors such as distance, delay, and bandwidth, to determine the best route for data packets.
Which routing protocol is known for its fast convergence time and is commonly used in mission-critical networks?
D
Correct answer
Explanation
EIGRP (Enhanced Interior Gateway Routing Protocol) is known for its fast convergence time, making it suitable for mission-critical networks where rapid adaptation to network changes is essential.
Which routing protocol is commonly used in service provider networks and supports traffic engineering?
D
Correct answer
Explanation
MPLS (Multiprotocol Label Switching) is commonly used in service provider networks and supports traffic engineering, allowing for the optimization of data traffic flow and improved network performance.
What is the role of a routing policy in network routing?
-
To determine the best path for data packets
-
To manage network traffic
-
To assign IP addresses
-
To control how data packets are forwarded
D
Correct answer
Explanation
A routing policy defines the rules and criteria used to control how data packets are forwarded in a network, influencing the path selection and traffic management.
Which routing protocol is commonly used in wireless networks and supports dynamic routing?
D
Correct answer
Explanation
OLSR (Optimized Link State Routing) is commonly used in wireless networks and supports dynamic routing, enabling efficient route discovery and adaptation to changing network conditions.
