IT 341 FINAL GMU QUESTIONS & VERIFIED ANSWERS
Converged Network? - Answers - A network where multiple types of traffic are all under
one network
Saves a lot of money
What is a Cisco Borderless Network? - Answers - Allows organizations to connect
anytime anywhere with any type of secure device easily
Borderless switched networks are what 4 things? - Answers - Hierarchical
Modular
Resilient
Flexible
Converged networks that are part of organization have 3 parts...what are they? -
Answers - Core - The center
Distribution - connection to the core
Access - Switches are used to connect to the distribution and give access to the users
Switched LANS allow for what? - Answers - Flexibility
traffic management
Features like: QoS, security, wireless
Fixed vs modular vs stackable switch form factor? - Answers - Fixed - number of ports
and abilities is set, no changes
modular - extra ports and other things can be added later
stack-able - switches are stacked a connected by cables to operate as one big switch
How does a switch learn what devices are on a network? - Answers - It builds a table
called a MAC address or CAM table
This table saves the device port.
, What does a switch do when it gets a frame that is not in the CAM table? - Answers -
The switch floods all known ports except the one that they got the frame from. The
correct port will accept the frame.
Store and forward vs cut-through? - Answers - - gets the entire frame and finds the
CRC, if valid the frame is forwarded
- forwards the frame before it has been fully received. It at least reads the destination
address
Collision domain? - Answers - all ports belong to the same collision domain
all ports have a collision domain of their own
How doe switches help alleviate network congestion? 3 - Answers - segment the
collision domains by port
provide full duplex communication
buffer large frames
Switch Boot Sequence? (5) - Answers - 1. POST
2. Run boot loader software
3. Boot loader does CPU initialization on a low-level
4. initializes the flash file system
5. Loads the IOS operating system
What are the steps required to find a IOS image? - Answers - - Tries to boot with info
already available in BOOT environment
- if not found, perform a top-to-bottom search through the file system
- IOS initializes the interface using the Cisco IOS commands from NVRAM
Whats NTP protocol - Answers - Network time protocol - uses to synchronize the clocks
of computer systems data networks
Split into a client and server
What is a VLAN? - Answers - Logical partition of layer 2
multiple VLANs can exist
each has its own broadcast
