NEW QUESTION # 583
A network administrator is configuring a database server and would like to ensure the database engine is listening on a certain port. Which of the following commands should the administrator use to accomplish this goal?
Answer: D
Explanation:
The "netstat -a" command is a command-line tool that can be used to display the status of all the network connections and listening ports on a server. The "netstat -a" command can show the protocol, local address, foreign address, and state of each connection or port. The network administrator can use this command to ensure the database engine is listening on a certain port by looking for the port number in the local address column and the "LISTENING" state in the state column. The other options are not commands that can be used to accomplish this goal, as they either do not display the listening ports, do not work on a server, or do not relate to the network.

NEW QUESTION # 584
An organization requires that backup media be stored at a location geographically separate from the primary data center. This practice is BEST described as which of the following?
Answer: B
Explanation:
Offsite storage involves keeping backup copies of data at a location physically separate from the primary site, protecting against site-specific disasters (fire, flood, etc.) that could destroy both production data and onsite backups simultaneously.
NEW QUESTION # 585
An organization has implemented a protection strategy to secure the network from unauthorized external access. The new Chief Information Security Officer (CISO) wants to increase security by better protecting the network from unauthorized internal access. Which Network Access Control (NAC) capability BEST meets this objective?
Answer: A
Explanation:
Port security is a technical control that restricts the access to network ports based on the Media Access Control (MAC) address of the device connected to the port. Port security can prevent unauthorized internal access to the network by preventing rogue devices, such as laptops, smartphones, or USB drives, from connecting to the network through an available port. Port security can also prevent unauthorized external access to the network by preventing devices from bypassing the firewall or other perimeter defenses by connecting directly to an internal port. Port security can also prevent network attacks, such as MAC spoofing, MAC flooding, or ARP poisoning, by limiting the number of MAC addresses allowed on a port or by disabling the port if an unauthorized MAC address is detected.
NEW QUESTION # 586
In what type of attack does an attacker try, from several encrypted messages, to figure out the key used in the encryption process?
Answer: D
Explanation:
Explanation/Reference:
Explanation:
In this question, the attacker is trying to obtain the key from several "encrypted messages". When the attacker has only encrypted messages to work from, this is known as a Ciphertext-only attack.
Cryptanalysis is the act of obtaining the plaintext or key from the ciphertext. Cryptanalysis is used to obtain valuable information and to pass on altered or fake messages in order to deceive the original intended recipient. This attempt at "cracking" the cipher is also known as an attack.
The following are example of some common attacks:
Chosen Ciphertext. Portions of the ciphertext are selected for trial decryption while having access to the corresponding decrypted plaintext
Known Plaintext. The attacker has a copy of the plaintext corresponding to the ciphertext Chosen Plaintext. Chosen plaintext is encrypted and the output ciphertext is obtained Ciphertext Only. Only the ciphertext is available
Incorrect Answers:
A: With a Known Plaintext attack, the attacker has a copy of the plaintext corresponding to the ciphertext.
This is not what is described in the question.
C: With a Chosen-Ciphertext attack, the attacker has a copy of the plaintext corresponding to the ciphertext. This is not what is described in the question.
D: With a Plaintext-only attack, the attacker does not have the encrypted messages as stated in the question.
