If an engineer wants to verify changes that she has been making on a router, which commands will allow her to check the routers current configuration before saving?

Group of answer choices.

a. Show flash

b. Show version

c. Show controllers

d. Show running-config

e. Show startup-config

d. Show running-config

Explanation:

A router can be defined as a network device that is designed typically for forwarding data packets between two or more networks based on a well-defined routing protocol.

Basically, it is an electrical device or node that is designed to connect two (2) different networks (in different locations) together and allows them to communicate.

Generally, routers are configured using a standard routing protocol with an IP address as the default gateway.

A routing protocol can be defined as a set of defined rules or algorithms used by routers to determine the communication paths unto which data should be exchanged between the source router and destination or host device.

In order to send packets to a remote destination using a router, these three (3) parameters must also be configured on a host.

I. Default gateway

II. IP address

III. Subnet mask

After a router successfully determines the destination network, the router checks the routing table for the resulting destination network number. If a match is found, the interface associated with the network number receives the packets. Else, the default gateway configured is used. Also, If there is no default gateway, the packet is dropped.

In Computer networking, network devices such as routers and switches are usually configured (programmed) through the use of specific network commands commonly referred to as configs e.g show int description, config terminal (config t), show IP address, etc.

In this scenario, the command which will allow her to check the router's current configuration before saving is Show running-config. It would display all the necessary information such as router name, banner of the day (BOTD), VLans, ports, default gateway, etc., about the router and its current firewall configurations.
