Protocol for POP3
The email is downloaded to the client computer
Imap protocol
The client application manages the email while its stored on the server
RDP protocol
The Windows Remote Desktop application utilizes this protocol to provide secure, encrypted transmissions.
SNMP
This protocol can be used to monitor and gather information about network traffic and can alert network administrators about adverse conditions that need attention
SMTP
This protocol is used to send mail messages to a mail server.
The TCP and UDP protocols both exist at what layer of the OSI model?
Transport
At what layer of the OSI model do the IP, ICMP, and IGMP protocols operate?
Network
When using a Windows domain, what is the domain-level account for each user known as?
Global account
The frame header at the Data Link layer includes hardware addresses of the source and destination NICs.
What is another name for this address?
Mac
When creating network diagrams, what icon description typically represents a network router?
An icon that has a hockey-puck shape with two arrows pointing inward and two arrows pointing outward.
When is it appropriate to utilize the NAT network connection type?
Whenever the VM does not need to be access at a known address by other network nodes.
What is assigned to each node on a network, which is then used by the Network layer to uniquely identify the node
Ip addresses
A policy in which all exit doors for a building stay unlocked during a fire is an example of what type of policy?
Fail-open
What is an example of encapsulation?
The addition of a header to the data inherited from the layer above in the OSI model.
HTTP, IMAP4,FTP, and Telnet are all examples of protocols that operate at what layer of the OSI model?
Layer 7
A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?
HTTP, TCP, IP, Ethernet
What accurately reflects what occurs when a message is too large to transport on a network?
The message is divided into smaller messages called segments (for TCP) or datagrams (for UDP).
At what layer of the OSI model does a network switch normally operate?
Layer 2
What type of network traffic requires QOS
Virtual classroom
What is correct about network protocols?
They define how messages are exchanged between the source and the destination.
Which PDU format is used when bits are received from the network medium by the NIC of a host?
Frame
The difference between a switch and a router is that a switch belongs only to its local network and a router belongs to two or more local networks.
True
A Switch (virtual switch) or bridge is a logically defined device that operates at both datalink and physical layer of the OSI model?
False
Servers that have a NOS installed require less memory, processing power, and storage capacity than clients because servers are called on to handle only light processing loads and requests from multiple
False
