Answer:
3
Explanation:
Heap sort pick an item from the first or last position in an array and compares it with other items in other positions in the array, swapping position if they meet the condition.

Answer: A VLAN mismatch
Explanation:
The VLAN mismatch is the process when the both ends of the truck line are not connected correctly and properly between the two switches.
- The configuration of the VLAN is done correctly as it is important to connecting the VLAN on either of the ends for avoiding the VLAN mismatch occurrence.
- By default the truck allow the VLAN 2094 for traversing the trunk by using the native VLAN in the form of VLAN 1.
Therefore, VLAN mismatch is the correct answer.
Answer:
Correct answer is option B (The reason for using supertypes is to minimize the number of nulls and to minimize the likelihood of redundant relationships)
Explanation:
Entity supertype
A entity supertype is a generic entity type which is related with one or more subtypes.
Use of entity supertype:
The reason for using entity supertype is to reduce redundant relationships and it is also used to minimize the number of nulls.
DHCP operations fall into four phases: server discovery, IP lease offer, IP lease request, and IP lease acknowledgement. These stages are often abbreviated as DORA for discovery, offer, request, and acknowledgement.
Explanation:
- DHCP provides reliable IP address configuration, while reducing network administration.
- Discovery : The DHCP client broadcasts a DISCOVER message on the network subnet using the destination address or the specific subnet broadcast address. A DHCP client may also request its last known IP address
- Offer :When the server receives a DISCOVER message from a client, which is an IP address lease request, the DHCP server reserves an IP address for the client and makes a lease offer by sending a OFFER message to the client.
- Request : In response to the DHCP offer, the client replies with a REQUEST message, broadcast to the server,[a] requesting the offered address.
- Acknowledge : When the DHCP server receives the REQUEST message from the client, the configuration process enters its final phase. The acknowledgement phase involves sending a ACK packet to the client.
