What is a network namespace in Linux?

A method to prioritize network traffic

An isolated network stack with its own interfaces, routes, and firewall rules

A virtual interface that can be used for bonding

A routing table that is used for policy routing

What is the primary purpose of network interface bonding in Linux?

To create a virtual interface that can be used for network isolation

To combine multiple physical interfaces into a single logical interface for redundancy or increased throughput

To prioritize network traffic based on source IP address

To assign multiple IP addresses to a single physical interface

What is the purpose of the tc command in Linux?

To manage network interface bonding

To configure IP addresses on interfaces

To configure traffic control, including queuing disciplines, classes, and filters

A company's web server is experiencing congestion on its 1 Gbps uplink. The administrator wants to prioritize HTTP traffic (port 80) over other traffic, giving HTTP a guaranteed 500 Mbps and limiting other traffic to 200 Mbps. Which tc configuration is appropriate?

Use iptables to mark port 80 packets and then use tc filter to match the mark.

Use a PRIO qdisc with three bands and assign port 80 to band 0.

Create an HTB qdisc with two classes: one for HTTP with rate 500mbit and one for other traffic with rate 200mbit, and add a filter to classify port 80 traffic.

Use a TBF qdisc with a rate of 500mbit and a filter for port 80.

Which command is used to add a second IP address to an existing network interface without creating a separate alias interface?

ip addr change 192.168.1.2/24 dev eth0

ip link set eth0 address 192.168.1.2

ip addr add 192.168.1.2/24 dev eth0

ifconfig eth0:1 192.168.1.2 netmask 255.255.255.0 up
