• Gateway/Next Hop

Multiple Choice

A static route can be described as

• A manually configured route in a network.
• A route that is only used for backup purposes.
• An automatically generated route in a network.
• A route that changes dynamically based on network conditions.

Multiple Choice

Static routes can be problematic if

• they require less configuration than dynamic routes
• they automatically update with new devices
• they are always faster than dynamic routes
• they do not adapt to network changes

Multiple Choice

Explain a local route, in networking

• A local route is used to connect different networks.
• A local route is a route that only applies to external traffic.
• A local route is a type of route used for internet access.
• A local route is a route used to reach destinations within the same local network or subnet.

​Router A:

• The router is directly connected to networks 10.0.1.0/24 (via interface G0) and 10.0.2.0/24 (via interface G1).

• The router has been configured with static routes to 10.0.3.0/24 and 10.0.4.0/24, both of which are reachable via interface G1.

Router B:  

• Configured in the same way as Router A.

• The networks 10.0.2.0/24 and 10.0.3.0/24 are directly connected, and the paths to 10.0.1.0/24 and 10.0.4.0/24 are configured as static entries.

Router C: 

• Configured differently than Routers A and B. 

• It is directly connected to 10.0.3.0/24 and 10.0.4.0/24, but the only static route configured is for 0.0.0.0/0. This is a default route. While the router has no specific knowledge of networks 10.0.1.0/24 and 10.0.2.0/24, it will forward packets for these destinations over its G0 interface.

Multiple Choice

Understanding routing tables is important because

• they are used to store user passwords.
• they provide a graphical interface for network management.
• they determine the best paths for data transmission in a network.
• they are only relevant for wireless networks.

​When forwarding a packet inside a network, it will only need the DATA LINK LAYER (MAC).

If it needs to go OUTSIDE of the network, the MAC address destination will be the ROUTER.

From there, it uses IP addressing to get to the next router.

Multiple Choice

To forward a packet to another network, what layer is the OSI model will be used?

• Network layer (Layer 3)
• Application layer (Layer 7)
• Data Link layer (Layer 2)
• Transport layer (Layer 4)

Multiple Choice

To forward a packet within a subnet, what layer would be used?

• Data Link layer (Layer 2)
• Transport layer (Layer 4)
• Network layer (Layer 3)
• Application layer (Layer 7)

Multiple Choice

According to the image, how many hops did it take for HOST B to reach its destination?

• 1

• 2

• 5

• 9

Multiple Choice

A hop (in routing) is defined as

• A hop is the transfer of data between two network devices.
• A hop is the total number of devices in a network.
• A hop refers to the speed of data transfer.
• A hop is the distance between two routers.

Multiple Choice

Can multiple hops exists when forwarding data?

• Data forwarding requires a direct connection without hops.
• No, data can only be forwarded in a single hop.
• Yes, multiple hops can exist when forwarding data.
• Multiple hops are not possible in any network.

Multiple Choice

A router should not be placed inside a subnet because

• A router should be placed in the center of a subnet.
• A router can improve subnet performance.
• A router is needed to manage devices within a subnet.
• A router connects different networks, not placed inside a subnet.

Multiple Choice

Routers are used to connect what to what?

• Routers connect devices to power sources.
• Routers connect computers to printers.
• Routers connect different networks to each other.
• Routers connect users to the internet directly.

Multiple Choice

What is the purpose of an edge router?

• To provide wireless connectivity to devices
• To serve as a firewall for internal networks
• To connect an internal network to external networks and manage data traffic between them.

• To store data for backup purposes

Multiple Choice

Why use an internal router alongside an edge router?

• An internal router connects to external networks while an edge router manages local traffic.
• Both internal and edge routers serve the same purpose in a network setup.
• An internal router is only used for wireless connections, while an edge router is for wired connections.
• An internal router improves local network efficiency and security, while an edge router connects to external networks.

Multiple Choice

What tool displays the routing table?

• netstat or show route

• ifconfig
• traceroute
• ping

Multiple Choice

What tracks a packets route to its destination?

• ping
• netstat
• ipconfig
• traceroute

Multiple Choice

Dynamic routing is generally better for a network environment because

• Dynamic routing is more adaptable to network changes.
• Dynamic routing is less secure than static routing.
• Dynamic routing requires more manual configuration.
• Dynamic routing is slower than static routing.

Multiple Choice

Dynamic routes uses what to calculate paths to be more efficient?

• Static routes
• Routing algorithms
• Network protocols
• Data packets

Multiple Choice

RIP protocol has a max hop number of

• 20
• 15
• 25
• 10

Multiple Choice

EIGRP is proprietary to what networking company?

• Juniper Networks
• Arista Networks
• Hewlett Packard Enterprise
• Cisco Systems

Multiple Choice

EIGRP uses these metrics to determine its routing path.

• Bandwidth, delay, load, reliability, and MTU
• Throughput, congestion, distance, and power
• Latency, bandwidth, distance, and security
• Cost, speed, distance, and frequency

Multiple Choice

The advantage of OSPF?

• Fast convergence and efficient routing.
• Limited scalability and flexibility.
• Complex configuration and management.
• Slow routing and high latency.

Multiple Choice

BGP is used to scale what?

• The management of user accounts on a network.
• The encryption of data for security purposes.
• The routing of data across the internet.
• The storage of data in cloud services.

Multiple Choice

BGP uses CIDR to do what?

• Use static routing protocols exclusively.
• Aggregate IP address ranges for efficient routing.
• Route IP addresses without aggregation.
• Enhance security through encryption.

Multiple Choice

Multiple Choice

Which routing protocol is the most effective?

• RIP (Routing Information Protocol)
• OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol) are among the most effective routing protocols.
• EIGRP (Enhanced Interior Gateway Routing Protocol)
• IGRP (Interior Gateway Routing Protocol)
