Answer:

Alice's public key

Explanation:A Public key is a key that can be used for verifying digital signatures generated using a corresponding private key which must have been sent to the user by the owner of the digital signature.

Public keys are made available to everyone required and they made up of long random numbers.

A digital signature signed with a person's private key can only be verified using the person's private key.

IPSec Tunnel mode and IPSec Transport mode so here we are using IPsec transport mode which is used for end to end communications between a client and a server in this original IP header is remain intact except the IP protocol field is changed and the original protocol field value is saved in the IPSec trailer to be restored when the packet is decrypted on the other side due to this arrangement you need to use application based firewall because there are certain specific rules that can address the particular field (explained above-change in IP protocol field) which at the other end need to be same so at the type of decryption, original IP protocol field can be matched.

For an external usb hard drive attached to a computer, which is more suitable: a writethrough cache or a block cache
Charra [1.4K]

Disk access is way slower than memory access. Caching is a technique to improve the disk access time.  Block cache is a caching technique which reduces disk accesses time.  Here a portion of disk is bought to cache for reading and a modified blocks are first changed in cache but reflected in the disk at one go.  On the other hand with write through caching each modified block is written to cache and at the same time it is written to the disk.  Write- through caching requires more disk I/O so they can have a negative effect on the performance.

Which file contains full and incremental back-up information for use with the dump/restore utility?
Ivahew [28]

The file that contains full and incremental back-up information for use with the dump/restore utility is <u>/etc/dumpdates.</u>

<u></u>

<h3>What is dump/restore utility ?</h3>

Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. Subsequent incremental backups can then be layered on top of the full backup.

The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Single files and directory subtrees may also be restored from full or partial backups in interactive mode.

Which of the following is true about binary search. A. It uses binary numbers in its algorithm B. It is slower than sequential s
trapecia [35]

Answer:

<u> A. It uses binary numbers in its algorithm</u>

Explanation:

A Binary search is a type of algorithm designed to look through <em>only </em>a sorted array of data for a particular item.

It is<em> more efficient (faster) </em>than sequential search since the algorithm doesn't have to look up the entire array of data, but simply repeatedly divide in half the section of the array that could contain the searched item.
