NET-07-P1 IPv4 & IPv6 Static Routing

Question 1

How does a Router Operate?

Answer 1

One of the router’s main jobs is to select the best path for a packet. The decision is based on its destination address

Question 2

In the first step, the router decides whether to process a packet or ignore it. Routers will ignore packets with errors or packets they don’t know how to process

Answer 2

Packet Forwarding Review: Examiniation

Question 3

In the second step, The router examines the Layer 2 address to decide if the packet was intended for itself (the default gateway), and verifies the integrity of the frame using the FCS (Layer 2 trailer)

Answer 3

Packet Forwarding Review: Decapsulation

Question 4

In the third step, the router decides where to forward the packet to, based on its destination IP address and the routing table

Answer 4

Packet Forwarding Review: Decision-Making

Question 5

In the fourth step, the router re-encapsulates the packet with new Layer 2 headers for the next hop (MAC address of the next hop), according tot eh decision made in step 3

Answer 5

Packet Forwarding Review: Encapsulation

Question 6

In the fifth step, after a decision is made, the router forwards the packet to the interface from which the packet must exit

Answer 6

Packet Forwarding Review: Forwarding

Question 7

Any network that is note connected locally to the router

Answer 7

Remote Network

Question 8

User enters every network manually in the routing table

Answer 8

Static method

Question 9

the router automatically learns the remote network from the routing tables of adjacent routers, by using various protocols

Answer 9

Dynamic Method

Question 10

When to Use static routing

Answer 10

Network administrators decide if and when to use Static Routing, based on network requirements

Question 11

is a better choice when routing to and from stub networks. consist of a single router that sends and receives non-local traffic via a single path

Answer 11

Stub Networks

Question 12

is simple and secure and saves resources, it does not provide a sufficient level of scalability in larger networks

Answer 12

Small networks

Question 13

Manually configured route that forwards traffic to a specific network

Answer 13

Standard Static Route

Question 14

Typically used as a Gateway of Last Resort, which is used for any packet that does not have a destination route in the routing table

Answer 14

Default Static Route
