Important Cisco 100-160 CCST Cybersecurity Exam Questions

Answer: B

Explanation:

According to the CCST Cybersecurity course, NIST guidelines (SP 800-63B) recommend a minimum password length of 8 characters for user-generated passwords, without requiring overly complex composition rules, but encouraging longer passphrases for increased security.

'NIST guidelines specify that user-generated passwords must be at least 8 characters in length, and systems should allow passwords up to at least 64 characters.'

Answer: B

Explanation:

The CCST Cybersecurity material explains that MAC address filtering is a wireless security measure that allows only devices with approved hardware addresses to connect. If the laptop's MAC address is not on the allow list, the connection will be blocked even if the SSID is correct.

'Wireless access points can be configured with MAC address filters to limit network access to authorized devices. If a device's MAC address is not on the permitted list, the connection will fail regardless of credentials.'

(CCST Cybersecurity, Basic Network Security Concepts, Wireless Security section, Cisco Networking Academy)

A is unlikely because non-broadcast SSIDs can still be manually connected to.

B is correct: MAC address filtering would block an unregistered device.

C would cause IP issues after association, not prevent initial connection.

D (open authentication) would allow connection, so it's not the cause here.

Answer: C

Explanation:

The CCST Cybersecurity Study Guide explains that HTTP (port 80) transmits data in cleartext, making it susceptible to interception. Even if data is stored securely in an encrypted database, sensitive information can be compromised during transmission if HTTPS (port 443) is not used.

'When HTTP is used instead of HTTPS, all form inputs and transmitted data are sent in plaintext over the network, where they can be intercepted by attackers.'

Answer: A, D

Explanation:

The CCST Cybersecurity course defines a strong password as one that:

Is at least 8--12 characters long

Uses a mix of uppercase, lowercase, numbers, and symbols

Avoids dictionary words, personal information, and predictable patterns

'Strong passwords combine length, complexity, and unpredictability, making them resistant to brute force and dictionary attacks.'

(CCST Cybersecurity, Essential Security Principles, Authentication and Access Control section, Cisco Networking Academy)

A is correct: It's long, mixed case, includes numbers and symbols, and is not easily guessable.

B is incorrect: It's based on a date, which is predictable.

C is incorrect: Short and based on a dictionary word.

D is correct: Uses complexity and length with leetspeak for added unpredictability.

Answer: D

Explanation:

The CCST Cybersecurity Study Guide highlights that SSH (Secure Shell) provides encrypted communication for secure remote access and file transfer (using SCP or SFTP) over unsecured networks. This ensures confidentiality and integrity of the files in transit.

'SSH encrypts all data exchanged between client and server, protecting credentials and file contents from interception. It is the preferred protocol for secure device management and file transfers across untrusted networks.'

(CCST Cybersecurity, Basic Network Security Concepts, Secure Remote Management section, Cisco Networking Academy)

A (Telnet) transmits data in plaintext.

B (HTTP) is unencrypted web traffic.

C (TFTP) is a simple, insecure file transfer protocol without encryption.

D is correct: SSH secures configuration file transfers across insecure networks.
