What is the purpose of router configuration?
To bake cookies
To set up and manage the routing functions of a router
To walk the dog
To watch TV
Explain the difference between static and dynamic routing in router management.
Static routing is more secure than dynamic routing.
Static routing uses wireless connections, while dynamic routing uses wired connections.
Static routing uses manually configured routes, while dynamic routing uses protocols to automatically update and maintain routing tables.
Static routing is used for data transmission, while dynamic routing is used for voice transmission.
How can you secure a router from unauthorized access?
Use a simple and common password
Leave the default password unchanged
Set up strong and unique passwords
Share the password with everyone
What is the role of a routing table in a router?
It stores information about the best paths for forwarding data packets.
It controls the temperature of the router
It stores the router's password
It plays music for the router
Describe the process of updating a routing table using routing protocols.
The routing table is updated by manually entering the information
The routing table is updated by using a GPS system to track the best routes
The routing table is updated by exchanging routing information using routing protocols.
The routing table is updated by sending emails to other routers
What is the function of a routing protocol in a network?
To encrypt data transmission between networks
To block all incoming and outgoing traffic
To determine the best path for data to travel from one network to another.
To automatically update software on network devices
What are the common routing protocols used in router management?
LAN, WAN, MAN, PAN
TCP, UDP, HTTP, FTP
RIP, OSPF, EIGRP, BGP
IPv4, IPv6, MAC, DNS
Explain the concept of distance vector routing.
Distance vector routing is a type of algorithm used by routers to determine the best path for data packets based on distance or hop count.
Distance vector routing is a type of algorithm used by routers to determine the best path for data packets based on IP address.
Distance vector routing is a type of algorithm used by routers to determine the best path for data packets based on signal strength.
Distance vector routing is a type of algorithm used by routers to determine the best path for data packets based on packet size.
What is the significance of link-state routing in routing protocols?
Link-state routing protocols use the complete network topology to make routing decisions.
Link-state routing protocols use distance-vector routing instead of the complete network topology.
Link-state routing protocols do not consider network topology when making routing decisions.
Link-state routing protocols use only a small portion of the network topology to make routing decisions.
Differentiate between interior gateway protocols and exterior gateway protocols.
Interior gateway protocols are used for local area networks, while exterior gateway protocols are used for wide area networks.
Interior gateway protocols are used for data encryption, while exterior gateway protocols are used for data decryption.
Interior gateway protocols are used for wireless communication, while exterior gateway protocols are used for wired communication.
Interior gateway protocols are used within an autonomous system, while exterior gateway protocols are used between different autonomous systems.
What is the main difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses
IPv4 is faster than IPv6
IPv4 is more secure than IPv6
IPv4 and IPv6 have the same addressing format
What is the purpose of IPv6 over IPv4?
IPv6 provides a larger address space compared to IPv4
IPv6 has better backward compatibility with older devices
IPv6 has faster data transmission speed than IPv4
IPv6 has weaker security features compared to IPv4
In the context of the network layer, which of the following best describes the data plane function?
Determines the route taken by packets from source to destination.
Moves packets from input to output ports within a router.
Implements routing algorithms across the network.
Manages end-to-end congestion control.
The difference between forwarding and routing is that:
Forwarding is local, routing is network-wide.
Forwarding uses IP addresses, routing uses MAC addresses.
Forwarding is in software, routing is in hardware.
Forwarding is network-wide, routing is local.
Which switching method copies packets to the router’s main memory under CPU control?
Switching via interconnection network
Switching via memory
Switching via bus
Crossbar switching
In a network using DHCP, a host boots up and sends a DHCP Discover message. What is the next message expected in the process?
DHCP Request
DHCP Offer
DHCP Ack
DHCP Nack
A company uses the private IP range 192.168.10.0/24 for its internal network and implements NAT. An internal host with IP 192.168.10.15 sends a request to an external server. The NAT router translates the source to 203.0.113.5:6000. When the server replies, what will the NAT router do?
Drop the reply because it’s from an external address.
Forward the reply to 192.168.10.15 using the mapping in its NAT table.
Broadcast the reply to all internal hosts.
Send an ICMP redirect to the server.
In a network using DHCP, a host moves to a new subnet and sends a DHCP Request message with the previously used IP address. The DHCP server responds with a DHCP NAK. What does this mean?
The requested IP is no longer available or valid.
The host must use a static IP.
The request was successful.
The server is down.
A company’s internal network uses IPv6, but their ISP only provides IPv4 connectivity to the Internet. They want their IPv6 hosts to reach IPv4 services on the web without replacing their core routers. Which solution allows IPv6 packets to travel across the IPv4 Internet by wrapping them in IPv4 headers?
Dual-stack routers
NAT-PT
6to4 tunneling
BGP for IPv6
A company uses SNMP to monitor router CPU usage. Which SNMP message type would the manager use to retrieve this data?
GET
SET
TRAP
INFORM
