Q

What command shows you ping response times and also each hop a packet takes as it traverses a network?

A

Tracert.
Traceroute: Traceroute is a utility that records the route (the specific gateway computers at each hop) through the Internet between your computer and a specified destination computer. It also calculates and displays the amount of time each hop took. Traceroute is a handy tool both for understanding where problems are in the Internet network and for getting a detailed sense of the Internet itself.

Example with command prompt: tracert www.whatis.com

Q

Which of the following enables one to utilize a computer as if they were on a corporate network despite being on the internet and not in the office?

A

VPN
Virtual Private Network: is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization’s network. A VPN ensures privacy through security procedures and tunneling protocols such as the Layer Two Tunneling Protocol ( L2TP ). Data is encrypted at the sending end and decrypted at the receiving end.

Q

What type of server is used to translate host names to IPs?

A

DNS
Domain Name System: DNS is an abbreviation for Domain Name System, a system for naming computers and network services that is organized into a hierarchy of domains. DNS naming is used in TCP/IP networks, such as the Internet, to locate computers and services through user-friendly names. When a user enters a DNS name in an application, DNS services can resolve the name to other information associated with the name, such as an IP address.

Q

What is the min category cable used for 100Mbps?

A

CAT5
Short for Category 5, network cabling that consists of four twisted pairs of copper wire terminated by RJ45 connectors. Cat-5 cabling supports frequencies up to 100 MHz and speeds up to 1000 Mbps. It can be used for ATM, token ring, 1000Base-T, 100Base-T, and 10Base-Tnetworking.

Computers hooked up to LANs are connected using Cat-5 cables, so if you’re on a LAN, most likely the cable running out of the back of your PC is Category 5.

Q

What protocol would be appropriate for transferring/hosting video?

A

UDP
User Datagram Protocol: is an alternative communications protocol to Transmission Control Protocol (TCP) used primarily for establishing low-latency and loss tolerating connections between applications on the Internet. Both UDP and TCP run on top of the Internet Protocol (IP) and are sometimes referred to as UDP/IP or TCP/IP. Both protocols send short packets of data, called datagrams.

Q

What routing protocol is most commonly used to determine best routes within a network and also utilizes a distance-vector routing algorithm?

A

RIP (routing information protocol)
Routing Information Protocol: is a widely-used protocol for managing router information within a self-contained network such as a corporate local area network (LAN) or an interconnected group of such LANs. RIP is classified by the Internet Engineering Task Force (IETF) as one of several internal gateway protocols (Interior Gateway Protocol).

Q

What is an advantage of a single-mode fiber?

A

Lower lag time.

In optical fiber technology, single mode fiber is optical fiber that is designed for the transmission of a single ray or mode of light as a carrier and is used for long-distance signal transmission. For short distances, multimode fiber is used.

Single mode fiber has a much smaller core than multimode fiber.
