Question 112

Sarah, an ethical hacker at a San Francisco-based financial firm, is testing the security of their customer database after a recent data exposure incident. Her analysis reveals that the sensitive client information is safeguarded using a symmetric encryption algorithm. She observes that the algorithm processes data in 64-bit blocks and supports a variable key size from 32 to 448 bits. During her penetration test, Sarah intercepts a ciphertext transmission and notes that the encryption was developed as a replacement for DES, an older algorithm. She aims to determine if the algorithm’s flexible key size could be susceptible to brute-force attacks. The algorithm is also noted for its use in secure storage, a critical application for the firm’s data protection.

Which symmetric encryption algorithm should Sarah identify as the one used by the firm?

Options:

A.

RC4

B.

Twofish

C.

AES

D.

Blowfish

Question 113

During enumeration, a tool sends requests to UDP port 161 and retrieves a large list of installed software due to a publicly known community string. What enabled this technique to work so effectively?

Options:

A.

Unencrypted FTP services storing software data

B.

The SNMP agent allowed anonymous bulk data queries due to default settings

C.

Remote access to encrypted Windows registry keys

D.

SNMP trap messages logged in plain text

Question 114

During a covert red team engagement, a penetration tester is tasked with identifying live hosts in a target organization’s internal subnet (10.0.0.0/24) without triggering intrusion detection systems (IDS). To remain undetected, the tester opts to use the command nmap -sn -PE 10.0.0.0/24, which results in several " Host is up " responses, even though the organization’s IDS is tuned to detect high-volume scans. After the engagement, the client reviews the logs and is surprised that the scan was not flagged. What allowed the scan to complete without triggering alerts?

Options:

A.

It used TCP ACK packets that were allowed through.

B.

It used UDP packets that bypassed ICMP inspection.

C.

It scanned only the ports open in the firewall whitelist.

D.

It performed an ICMP Echo ping sweep without port probing.

I used Cramkey Dumps to prepare for my recent exam and I have to say, they were a huge help.
Corey Mar 16, 2026
Really? How did they help you? I know these are the same questions appears in exam. I will give my try. But tell me if they also help in some training?
Kingsley
Do anyone guide my how these dumps would be helpful for new students like me?
Haris Mar 23, 2026
Absolutely! They are highly recommended for anyone looking to pass their certification exam. The dumps are easy to understand and follow, making it easier for you to study and retain the information.
Yusra
I passed my exam. Cramkey Dumps provides detailed explanations for each question and answer, so you can understand the concepts better.
Alisha Mar 6, 2026
I recently used their dumps for the certification exam I took and I have to say, I was really impressed.
Cecilia
Yes, I passed my certification exam using Cramkey Dumps.
Helena Mar 9, 2026
Great. Yes they are really effective
Reeva
Wow what a success I achieved today. Thank you so much Cramkey for amazing Dumps. All students must try it.
Amari Mar 7, 2026
Wow, that's impressive. I'll definitely keep Cramkey in mind for my next exam.
Question 115

During a red team operation on a segmented enterprise network, the testers discover that the organization’s perimeter devices deeply inspect only connection-initiation packets (such as TCP SYN and HTTP requests). Response packets and ACK packets within established sessions, however, are minimally inspected. The red team needs to covertly transmit payloads to an internal compromised host by blending into normal session traffic. Which approach should they take to bypass these defensive mechanisms?

Options:

A.

Port knocking

B.

SYN scanning

C.

ICMP flooding

D.

ACK tunneling
