Correction: ~3:30 Timestamp. IPv6 (Internet Protocol version 6) was not designed in 2017. It was actually developed in the mid-1990s to address IPv4 address exhaustion. The initial specification of IPv6 was published in 1998 as RFC 2460.
What is the new Internet Protocol designed in 2017 to deal with the previous versions address exhaustion? (IPv6)
What were the three types of Private IP addresses? (Select 3) (Single Class A, 16 Class B, 256 Class C)
This is a method of assigning Internet Protocol (IP) addresses that improves the efficiency of address distribution and replaces the previous system based on Class A, Class B, and Class C networks. (CIDR (Classless Inter-Domain Routing))
What does TCP stand for? (Transmission Control Protocol)
How many IP addresses would a 192.168.0.0/16 IPv4 address provide? (65,536 IP addresses)
This is a basic unit of information in network transmission. (A packet)
This layer in the OSI model provides services for network applications with the help of protocols to perform user activities. (The application layer)
What type of NAT is where 1 private IP is mapped to 1 public IP in a pool of public addresses and is allocated randomly as needed? (Dynamic NAT)
This is a way to map multiple local private IP addresses to a public IP address before transferring the information. (Network Address Translation (NAT)
This type of NAT is where multiple private IP addresses are translated using a single public IP address and a specific port. (Port Address Translation (PAT)
For Dynamic NAT, the NAT device maps a private IP with a public IP in a NAT table Public IPs are allocated randomly and dynamically from a pool. (True)
Which of the following best describes Port Address Translation(PAT)? (The NAT device records the source IP and source port in a NAT table)
What part of the DNS structure do com, org, net and io fall under? (Top-level domains)
What contains a DNS record that links the name www and the IP address that your laptop or device needs to communicate with the specific website? (A zone file)
Which of the following are the benefits of DNS? (Provides a Domain name structure, Better organization of names, Provides a dynamic system for protocols, services, and methods for storing, updating, and retrieving IP addresses for host computers)
This is a global decentralized distributed database that lets you store IP addresses and other data, and look them up using human-readable names like Google.com to translate them into a language that computers understand which are numeric IP addresses. (Domain Name System (DNS)
Which DNS record is a type of resource record that maps one domain name to another? (CNAME records)
What DNS record identifies which DNS server contains the current records for the domain? (Name Server (NS)
Which DNS record is a resource record that is created for you when you create your managed zone and specifies the authoritative information, including global parameters about a DNS zone? (SOA records)
This DNS record points a domain name to an IP address. (A and AAAA records)
This DNS record is a type of resource record that provides text information to sources outside your domain that can be used for a number of arbitrary purposes. (a TXT record)
What manages the distribution of the hardware resources of the computer efficiently and fairly among all the various processes running on the computer? (The Kernel)
What runs a separate version of the Linux kernel and sees the associated virtual machine as a userspace process on the physical host making it easy to run multiple virtual machines on a single host? (Kernal level virtualization)
What is an approach that enables efficient full virtualization using help from hardware capabilities on the host CPU? (Hardware-assisted Virtualization)
This is the process of running multiple operating systems on a server simultaneously. (Virtualization)
This is a small software layer that enables multiple operating systems to run alongside each other, sharing the same physical computing resources. (A Hypervisor)
What is a collection or stack of layers that are created from sequential instructions on a Docker file so each line in the docker file is run line by line, and a unique read-only layer is written to the image? (Docker Image)
A Read/Write layer is always added on top of the Read-Only layer when a container is created. (True)
These are packages of software that contain all of the necessary elements to run in any environment allowing you to virtualize the operating system and run anywhere, from a private data center to the public cloud or even on a developer's personal laptop. (Containers)
This is a single place for you to store and manage docker images. (a Container Registry)
What type of storage should you use if you're planning to store terabytes of pictures for web applications and you don't want to worry about scaling? (Object Storage)
What is a technology that is used to store data files on storage systems or cloud-based storage environments and is also the fastest available storage type? (Block Storage)
Which of the following are characteristics of Object Storage? (Unstructured data, Infinitely scalable, Not bootable)
This is normally storage that is presented to users and applications as a traditional network file system. (File Storage)
This type of storage is a flat collection of unstructured data. (Object Storage)
This is a metric that stands for Input/Output Operations/second, this value indicates how many different I/O operations a device or group of devices can perform in one second. (IOPS)
