Which of the following network vulnerability scan indicators BEST validates a successful, active scan?

A. The scan job is scheduled to run during off-peak hours.

B. The scan output lists SQL injection attack vectors.

C. The scan data identifies the use of privileged-user credentials.

D. The scan results identify the hostname and IP address.

A

I do not think it is D since host name and IP can be found using passive methods. They are not usually hidden. It is not A, it does not matter when the job is scheduled, it does not indicate a successful scan. It is not C, why would a vulnerability scan indicate a use of privileged user. Unless I do not understand what hat means. So it must be B. Since it is identifying an attack vector.

An analyst wants to implement a more secure wireless authentication for office access points. Which of the following technologies allows for encrypted authentication of wireless clients over TLS?

A. PEAP

B. EAP

C. WPA2

D. RADIUS

A

A. PEAP

EAP by itself is only an authentication framework.
PEAP (Protected Extensible Authentication Protocol) fully encapsulates EAP and is designed to work within a TLS (Transport Layer Security) tunnel that may be encrypted but is authenticated. The primary motivation behind the creation of PEAP was to help correct the deficiencies discovered within EAP since that protocol assumes that the communications channel is protected. As a result, when EAP messages are able to be discovered in the “clear” they do not provide the protection that was assumed when the protocol was originally authored.
PEAP, EAP-TTLS, and EAP-TLS “protect” inner EAP authentication within SSL/TLS sessions.

A database backup schedule consists of weekly full backups performed on Saturday at 12:00 a.m. and daily differential backups also performed at 12:00 a.m. If the database is restored on Tuesday afternoon, which of the following is the number of individual backups that would need to be applied to complete the database recovery?

A. 1

B. 2

C. 3

D. 4

A

B. 2

guys there are 3 kinds of backups a full backup which backs everything up , an incremental backup which backs that have been saved on the pc for that day , and if done again the next day it will again only back up the things that have been saved on the pc for that day. and finally there is the differential backup which will back up all the files that have been modified or saved since the last full back up so if you do a full backup on Sunday , and you do a differential backup on Monday the differential back will backup everything on the computer that was modified(edited, deleted or whatever) in addition to new things that was saved on the computer from sunday to Monday, and if you do another differential backup on Tuesday it will back all the things from Sunday to Tuesday so if you have to restore on Wednesday you will only need two backups the full backup from sunday and the differential backup from tuesday since that backup contains everything that happened from Sunday to tuesday .

Q

Which of the following encryption methods does PKI typically use to securely protect keys?

A. Elliptic curve

B. Digital signatures

C. Asymmetric

D. Obfuscation

A

C. Asymmetric

It is Asymetric. Since in all cases web or email Asymetric encryption is used to send a private (session key). Eliptical curve is a way of generating Asymetric keys. It is a poorly worded question though and hard to really pin point the answer but it is most likely Asymetric.

Public Key Infrastructure (PKI) uses a combination of asymmetric and symmetric processes. An initial “handshake” between communicating parties uses asymmetric encryption to protect the secret key which is exchanged to enable symmetric encryption

B. The portal will function as an identity provider and issue an authentication assertion.

C. The portal will request an authentication ticket from each network that is transitively trusted.

D. The back-end networks will function as an identity provider and issue an authentication assertion.

E. The back-end networks will request authentication tickets from the portal, which will act as the third-party service provider authentication store.

F. The back-end networks will verify the assertion token issued by the portal functioning as the identity provider.

A

C. The portal will request an authentication ticket from each network that is transitively trusted.

D. The back-end networks will function as an identity provider and issue an authentication assertion.

1) The user accesses the remote application using a link on an intranet, a bookmark, or similar and the application loads. 2) The application identifies the user’s origin (by application subdomain, user IP address, or similar) and redirects the user back to the identity provider, asking for authentication. This is the authentication request. 3) The user either has an existing active browser session with the identity provider or establishes one by logging into the identity provider. 4) The identity provider builds the authentication response in the form of an XML-document containing the user’s username or email address, signs it using an X.509 certificate, and posts this information to the service provider. 5) The service provider, which already knows the identity provider and has a certificate fingerprint, retrieves the authentication response and validates it using the certificate fingerprint. 6) The identity of the user is established and the user is provided with app access.

Q

A security analyst wishes to increase the security of an FTP server. Currently, all traffic to the FTP server is unencrypted. Users connecting to the FTP server use a variety of modern FTP client software.
The security analyst wants to keep the same port and protocol, while also still allowing unencrypted connections. Which of the following would BEST accomplish these goals?

A. Require the SFTP protocol to connect to the file server.

B. Use implicit TLS on the FTP server.

C. Use explicit FTPS for connections.

D. Use SSH tunneling to encrypt the FTP traffic.

A

C. Use explicit FTPS for connections.

The key part in this question is: “MODERN FTP client software.” Explicit FTPS is the newer method of FTPS transfer and has generally overtaken implicit FTPS use, with the exception of “legacy” systems. When explicit FTPS is used, a traditional FTP connection is established on the same standard port as FTP. Once the connection is made (before login), a secure SSL connection is established via port 21.
