the core, the distribution/aggregation layer, and the access/edge.

Question 19

north-south
east-west

Answer 19

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.

Question 20

iSCSi

Answer 20

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.

Question 21

unicast

Answer 21

Single sender and single receiver.
BOTH IPV4 and 6

Question 22

Broadcast

Answer 22

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.

Question 23

Multicast

Answer 23

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)

Question 24

Anycast

Answer 24

Ipv4 doesn’t support unless special BGP configurations are enabled.
IPv6 does support anycast.

Same as unicast, can choose nearest receiver.
