Answer:

D. Maintain a count of queue items.

Explanation:

For checking the full condition of a queue you have to check whether the number of elements in the array are equal to the size of the array.If they are equal then we can that the queue is full.

Checking frontindex equal to backindex is for checking if the queue is empty.

In option C we have to check for arrayFullException but it will not be a good approach.

So we conclude by saying that the answer is option D.

ValentinkaMS [17]

The SOA is the specific record type found in every zone and contains information that identifies the sever primarily responsible for the zone as well as some operational properties for the zone.

Explanation:

The Start of Authority Records (SOA) has the following information they are

Serial Number: This number is used to find when zonal information should be replicated.

Responsible person: The Email address of a person is responsible for managing the zone.

Refresh Interval: It specifies how often a secondary DNS server tries to renew its zone information.

Retry Interval: It specifies the amount of time a secondary server waits before retrying the zone information has failed.

Expires After: IT specifies the amount of time before a secondary server considers its zone data if it can't contact with the primary server.

Minimum TTL: It specifies the default TTL value for a zone data when a TTL is not supplied.

Describe and list advantages and disadvantages of each of the following backup types:

crimeas [40]

Answer:

Full back up

It creates complete copy of the source of data. This feature made it to the best back up with good speed of recovery of the data and simplicity.However, because it is needed for backing up of a lot of data, it is time consuming process,Besides it also disturbs the routine application of the technologist infrastructure. In addition large capacity storage is needed for the storage of the large volume of back up with each new creation.

Incremental back up: back up work at high speed thus saves time, Little storage capacity is needed. This type of back up can be run as many time as wished.

However, the restoration of data takes time, due to the time spent for restoration of initial back up and the incremental.

Differential Back up has very fast back up operation, because it only requires two pieces of back up.This is however slower compare to the Incremental.

The selective back up enable selection of certain type of file or folders for back up.

it can only be used to back up folders only when important data are needed only.Thus the storage capacity is low.

CPD eliminates back up window and reduces the recovery point objective.However, it has issue of compatibility with the resources to back up.,it is also expensive because its solutions are disk based.

Cloud based is affordable and save cost,It is easier to access. it is efficient,it can be access remotely for convenience.

However, Internet sources and some bandwidth must be available for access., always depends on third party providers,There is also problems encountered when switching providers.
