step 1 troubleshooitng
define the problem
step 2 troubleshooitng
hypothesize the probable cause
step 3 troubleshooitng
test hypothesis
step 4 troubleshooitng
create an action plan
step 5 troubleshooting
implement the action plan
step 6 troubleshooitng
verify the problem resolution
step 7 troubleshooitng
create a post-mortem report
which routing protocols supports vlsm
Routing Information Protocol v2 (RIPv2)
Open Shortest Path First (OSPF)
Intermediate System-to-Intermediate System (IS-IS)
Border Gateway Protocol (BGP)
Enhanced Interior Gateway Routing Protocol (EIGRP)
tcp header parts first 4 lines. top left, top right. middle top, middle middle.
source port, destination port.
sequence number, acknowledgement number.(top 4 lines)
tcp header bottom lines left left, left middle, left right lower side. bottom left
tcp right lower side
offset, reserved,tcp flags
checksum. (bottom left)
window, urgent pointer tcp options option.
udp header
source port, destination port
udp length, udp checksum
ipv6 address types
gobal routable= 2000-3999
link-local(APIPA) address= FE80
Multicast address= FF
No broadcast in IPv6
Which of the following answers refer to the layers that can be found in the three-tiered datacenter network architecture model?
the core, the distribution/aggregation layer, and the access/edge.
north-south
east-west
1.trafiic in and out of actual data center
2. traffic moving in between the media in the data center, doesn’t leave the data center.
iSCSi
Internet Small Computer Systems Interface or iSCSI is an Internet Protocol-based storage networking standard for linking data storage facilities.
send scsi commands over an ip network. makes remote disk look and operate like a local disk.
unicast
Single sender and single receiver.
BOTH IPV4 and 6
Broadcast
ONLY IPV4
Single sender, and multiple receivers.
broadcast receivers are connected to the same network as the sender.
IPv4 ONLY
Primarily used with ARP to find permanent physical addresses of devices.
Multicast
BOTH IPV4 AND IPV6
one sender is sending to a single group of devices within the network. For example broadcast is all devices in the network while multicast selects a single group from the broadcast group to send to.
IPv4(Class D) and IPv6 (FF)
Anycast
Ipv4 doesn’t support unless special BGP configurations are enabled.
IPv6 does support anycast.
Same as unicast, can choose nearest receiver.
