Secure Shell (SSH) Right Ans - 22 TCP
Telnet Right Ans - 23 TCP
SMTP - Simple Mail Transfer Protocol is used to send email over the
internet Right Ans - 25 TCP
DNS - Domain Name Service is used to resolve hostnames to IPs and
IPs to hostnames Right Ans - 53 TCP/UDP
DHCP - Dynamic Host Configuration Protocol. Auto config. of IP
address, subnet mask & other options. Requires a DHCP server, and
appliance integrated into a SOHO router.
Server to Client - Sends Message Right Ans - 67 UDP
,DHCP - Dynamic Host Configuration Protocol. Auto config. of IP
address, subnet mask & other options. Requires a DHCP server, and
appliance integrated into a SOHO router.
Client to Server - Receives Message Right Ans - 68 UDP
TFTP - Trivial FTP is used as a simplified version of FTP to put a file
on a remote host, or get a file from a remote host Right Ans - 69
UDP
Finger protocol (user information) Right Ans - 79 TCP
HyperText Transfer Protocol (HTTP) (browsing websites) Right
Ans - 80 TCP
Kerberos Right Ans - 88 UDP
POP3 - Post Office Protocol v3 is used to receive email from a mail
server Right Ans - 110 TCP
IMAP - Internet Message Access Protocol is used to receive email
from a mail server with more features than POP3 Right Ans - 143
TCP
,Hypertext Transfer Protocol Secure (HTTPS) Right Ans - 443 TCP
Lightweight Directory Access Protocol (LDAP) Right Ans - 389
TCP/UDP
Lightweight Directory Access Protocol Secure (LDAPS) Right Ans
- 636 TCP/UDP
Remote Desktop Protocol (RDP) Right Ans - 3389 TCP/UDP
How are analog transmissions waves measured which is the number
of cycles per second that's measured? Right Ans - Frequency
(also called hertz)
A Physical Layer device that converts an Ethernet signal from, for
example, fiber optic to copper transmission media Right Ans -
Media converter
1-green/white, 2-green, 3-orange/white, 6-orange Right Ans -
TIA-568A Wiring Pin Colors
, 1- orange/white, 2-orange, 3-green/white, 6-green Right Ans -
TIA-568B Wiring Pin Colors
Backbone that's more restrictive because they must rely on physical
device location to isolate departmental LANs from one another
Right Ans - Flat backbone
Minimizes traffic flowing between departmental LANs by replacing a
bus with one or more central switches Right Ans - Collapsed
backbone
When an IP receives a packet from a higher layer and adds
additional data in a new IP header to the packet Right Ans -
Encapsulation
What is this drawbacks of?
Fiber optic cabling is required to connect each departmental LAN to
the central switch
The central switch represents a single point of failure. If the switch
fails, no traffic can travel between departmental LANs Right Ans -
Drawbacks of a Collapsed backbone
