BASIC ROUTER CONFIGURATION

To enter the privileged mode on a Cisco router, the most commonly used command is:

Enable

Configure

Setup

Access

What interface on a router typically connects to a switch or another router?

Console port

Ethernet port

USB port

Serial port

What is the purpose of the default gateway setting on a device connected to a network?

To define the device's own IP address

To specify the subnet mask for the network

To identify the router for outbound traffic

To assign a unique identifier to the device

What command is used to display the current configuration of a Cisco router?

Show running-config

Display configuration

View startup-config

Print settings

What is the difference between the running configuration and startup configuration on a router?

The running configuration is volatile and lost on reboot, while the startup configuration is permanent.

The running configuration is for basic settings, while the startup configuration is for advanced options.

The running configuration is stored in RAM, while the startup configuration is stored in flash memory.

There is no difference; they are the same configuration.

What is the purpose of a static route on a router?

To automatically learn the best path to destinations

To manually define a specific route for traffic

To improve the security of communication between networks

To increase the bandwidth available for a specific connection

What does the command "show ip route" display on a Cisco router?

The current IP address configuration of the router interfaces

The routing table containing paths to different networks

The active connections established by the router

The MAC address table for connected devices

What is the function of Access Control Lists (ACLs) on a router?

To manage the routing table entries on the router

To filter and control traffic flow based on specific criteria

To improve the performance of data transfer across the network

To assign IP addresses to devices on the network

Which command is used to configure inter-VLAN routing on a Cisco router?

Show vlan

Configure interface Vlan

Set ip routing

Enable ip forwarding

What is the difference between RIP (Routing Information Protocol) and OSPF (Open Shortest Path First) for routing protocols?

RIP uses distance vector routing, while OSPF uses link-state routing.

RIP is more complex to configure than OSPF.

RIP is faster than OSPF for convergence after network topology changes.

OSPF requires a central server for route advertisement, while RIP is distributed.

What is the purpose of using NAT (Network Address Translation) on a router?

To improve the overall network performance by reducing traffic

To provide a layer of security by hiding internal network IP addresses.

To simplify network management for large and complex networks.

To increase the available pool of public IP addresses for a limited number of devices.

What is the difference between static NAT and dynamic NAT configurations?

Static NAT maps a single private IP address to a single public IP address, while dynamic NAT uses a pool of public IP addresses.

Static NAT is more secure than dynamic NAT.

Dynamic NAT requires more configuration than static NAT.

Static NAT is only used for internal network communication, while dynamic NAT is used for internet access.

How can Virtual Routing and Forwarding Instances (VRF) be used on a router?

To create separate and independent routing tables for different network segments.

To increase the maximum number of static routes that can be configured.

To simplify the process of managing ACLs on a router.

To provide redundancy and failover capabilities for routing protocols.

What is the function of Port Security on a router interface?

To configure the speed and duplex mode of the interface

To limit the number of MAC addresses allowed on the interface

To define the VLAN membership for the interface

To prioritize specific types of traffic on the interface

What is the purpose of using SSH (Secure Shell) for router access compared to Telnet?

SSH provides a graphical user interface for router configuration.

SSH encrypts communication for secure access to the router.

SSH offers faster connection speeds than Telnet.

SSH is a more complex protocol to configure than Telnet.

What does the command "copy running-config startup-config" achieve on a Cisco router?

It displays the current router configuration.

It saves the running configuration to the startup configuration, making it permanent after a reboot.

It resets the router to its factory default settings.

It copies the startup configuration to the running configuration.

What is the role of DHCP Snooping on a router?

To improve the performance of DHCP server operation

To prevent unauthorized devices from obtaining IP addresses from a DHCP server.

To automatically configure static routes on the router

To manage the assignment of VLAN memberships to devices

What is the main benefit of using Password Policies for router access?

Password policies simplify password management for multiple users.

Password policies enforce stronger password complexity for increased security.

Password policies automatically expire router passwords after a set period.

Password policies limit the number of login attempts to prevent brute-force attacks.

Which command is used to configure an IP address and subnet mask on a router interface?

Show ip interface

configure ip address <IP address> <subnet mask>

set interface ip <IP address>

route <IP address> <subnet mask>

Which basic verification command can be used to test connectivity between a router and another device?

Show ip interface

Ping

Traceroute

Telnet
