Question 1

An attacker scans a host with the below command. Which three flags are set? # nmap -sX host.domain.com

Options :

A : This is SYN scan. SYN flag is set.

B : This is Xmas scan. URG, PUSH and FIN are set.

C : This is ACK scan. ACK flag is set.

D : This is Xmas scan. SYN and ACK flags are set.

Answer: B

Question 2

An attacker with access to the inside network of a small company launches a successful STP manipulation attack. What will he do next?

Options :

A : He will create a SPAN entry on the spoofed root bridge and redirect traffic to his computer.

B : He will activate OSPF on the spoofed root bridge.

C : He will repeat this action so that it escalates to a DoS attack.

D : He will repeat the same attack against all L2 switches of the network.

Answer: A

Question 3

Which of the following commands checks for valid users on an SMTP server?

Options :

A : RCPT

B : CHK

C : VRFY

D : EXPN

Answer: C

Question 4

You are the lead cybersecurity analyst at a multinational corporation that uses a hybrid encryption system to secure inter-departmental communications. The system uses RSA encryption for key exchange and AES for data encryption, taking advantage of the strengths of both asymmetric and symmetric encryption. Each RSA key pair has a size of 'n' bits, with larger keys providing more security at the cost of slower performance. Thetime complexity of generating an RSA key pair is O(n*2), and AES encryption has a time complexity of O(n).

An attacker has developed a quantum algorithm with time complexity O((log n)*2) to crack RSA encryption.

Given *n=4000' and variable ‘AES key size’, which scenario is likely to provide the best balance of security

and

performance? which scenario would provide the best balance of security and performance?

Options :

A :

Data encryption with 3DES using a 168-bit key: Offers high security but slower performance due to 3DES-s inherent inefficiencies.

B :

Data encryption with Blowfish using a 448-bit key: Offers high security but potential compatibility issues due to Blowfish-s less widespread use.

C :

Data encryption with AES-128: Provides moderate security and fast encryption, offering a balance between the two.

D :

Data encryption with AES-256: Provides high security with better performance than 3DES, but not as fast as other AES key sizes.

Answer: C

Question 5

Which results will be returned with the following Google search query? site:target.com – site:Marketing.target.com accounting

Options :

A : Results from matches on the site marketing.target.com that are in the domain target.com but do not include the word accounting.

B : Results matching all words in the query.

C : Results for matches on target.com and Marketing.target.com that include the word “accounting”

D : Results matching “accounting” in domain target.com but not on the site Marketing.target.com
