What are 3 Attributes of IPv6?
Consists of 4 groups of 8 hexadecimal values, it is always a /64 subnet mask, and the notation can be shortened in some cases.

DNS is like a contact list for the internet, converting FQDN (ex: www.totalsem.com) into a Public IP address. How does this work?
Your computer stores the IP addresses that it learns in a host file and uploads that file to DNS at 3am every morning.
DNS connects to a server that has a host file, which contains a list of all FQDNs and their associated IP addresses.
The Local DNS server connects with a network of authoritative root and domain servers that store this information.

TCP is a connection-based protocol, and UDP is a connectionless protocol. How would you describe each of these behaviors?
TCP requires a connection to a server and a client, while UDP does not need to connect to a server or client.
TCP requires a connection to the internet, while UDP does not require a connection to the internet.
TCP requires a connection to be established prior to the exchange of data, while UDP allows the transfer of data without an prior connection.

Why is it necessary to use port numbers when data is being transferred between a Client and a Server?
Port numbers enhance the user of IPv4 addressing to allow connections o more servers.
Port numbers separate clients from servers.
Port numbers ensure that data gets to the correct application.

Raphael is asking to help Sonia configure her home router. What are some basic steps that Raphael should advise Sonia to do?
Configure WAN/LAN connections, change default password and SSID, and reserve IPs from the DHCP pool for devices that need static IPs.
Configure the LAN IP to match the local computer IP, change default password and SSID, and consider the DHCP range.
Configure WAN/LAN connections, change default password and SSID, and reserve IPs from the outside the DHCP pool for devices that need static IPs.

From this Routing Table entry, you know that Ports 1 and 2 represent connections to the router's physical ports. What else do you know from these Routing Table Entries? PORT 1 11.12.13.44 Connected LAN 11.12.13.0 PORT 2 192.168.7.1 Connected LAN 192.168.7.0
Port 1 has a Public IP and is likely connected to an ISP; Port 2 has a Private IP and is likely connected to a device on the Local Network.
Port 1 IP address is 11.12.13.44 and is connected to Port 2 via the connected 11.12.13.0 LAN.
Port 1 has a Private IP and is likely connected to a device on the local network; Port 2 has a Public IP and is likely connected to an ISP.
Port 1 IP address is 11.12.13.44 and is connected to Port 2 via the connected 192.168.7.0 LAN.
Port 1 has a Public IP and is likely connected to an ISP; Port 2 has a Private IP and is likely connected to a device on the Local Network.
What is the IP Address of the Device that is Translating website names to and from their Public IP addresses?

Alex is troubleshooting connectivity issues on a wired network and askes you for help. What will you advise him to check out first?
DHCP settings, link lights, and IP addressing.
Cable connections, link lights, and DHCP settings.
Cable connections, link lights, and the routing table.
Cable connections, link lights, and IP addressing.
Cable connections, link lights, and IP addressing.
You are called about a problem and told there are two computers plugged into the same switch, and they cannot see or talk to each other. The first step is to check for the existence of VLANs. Why??
If the computers are plugged into different ports, they must be on different VLANs and therefor different networks.
If the ports the computers are plugged into are configured with the same VLANs, the computers are on different networks.
If the ports the computers are plugged into are configured with different VLANs, the computers are on different networks.
If the computers are configured with different VLANs, they are on different networks.

Quality of Service (QoS) is a tool set that allows you to meter and adjust bandwidth priority for services using a port number, Mac Address, or IP Address. Why would you use this setting?
To ensure that your router receives the best quality of service from your ISP.
To receive the full amount of bandwidth that you are paying for.
To give bandwidth priority to a particular service, such as gaming or video streaming.

Why is Network Address Translation (NAT) so important to networking?
It is critical for the translation of IPv4 to IPv6 now that IPv6 is coming into maturity.
It allows a router to translate a public IP address to private IP addresses on another network.
It reduces the number of necessary public IP addresses by allowing local networks to use Private IP addresses and share a public IP address.
It reduces the number of necessary public IP addresses by allowing local networks to use Private IP addresses and share a public IP address.
How would you describe the difference between Public and Private IP Addresses?
Private IPs are Class A, B, and C, while Public IPs are Class D and E.
Private IPs are used to address devices on a LAN, while public IPs are used to connect one LAN to another with routers.
Private IPs are used for corporate networks, while public IPs are used for home networks.
Private IPs are not available to the public, while public IPs are availble to anyone.
Private IPs are used to address devices on a LAN, while public IPs are used to connect one LAN to another with routers.
What is the Default Gateway?
Your Router.
