62. Frage
What is the purpose of a disaster recovery plan (DRP)?
Antwort: A
Begründung:
A disaster recovery plan (DRP) is a documented set of procedures and strategies designed to guide an organization during the recovery process after a disaster or disruptive event has occurred. It encompasses the recovery of critical systems, applications, and data to ensure continuity of operations.
63. Frage
You are reviewing your company's disaster recovery plan.
Which two daily data backup actions should the plan include? (Choose 2.)
Antwort: C,D
Begründung:
The CCST Cybersecurity Study Guide emphasizes that backups should be stored off-site or in the cloud to ensure recovery even if the primary location is damaged or compromised.
"A comprehensive disaster recovery plan includes performing regular backups and ensuring copies are stored in locations not subject to the same physical risks as the primary site. Off-site storage and cloud-based backups provide resilience against local disasters." (CCST Cybersecurity, Essential Security Principles, Backup and Disaster Recovery section, Cisco Networking Academy) A is correct: Off-site removable media ensures recovery even if the main site is destroyed.
B is incorrect: Local-only backups are vulnerable to the same risks as production systems.
C is correct: Cloud services provide geographically separate storage with automated redundancy.
D is incorrect: RAID is for hardware fault tolerance, not a complete backup solution.
64. Frage
Why is it necessary to update firmware to the latest version?
Antwort: B
Begründung:
According to the CCST Cybersecurity Study Guide, firmware updates are a critical security maintenance task because vulnerabilities in firmware can be exploited by attackers to gain persistent control over hardware.
" Keeping firmware up to date is necessary to patch security vulnerabilities and weaknesses that could be exploited by threat actors. Vendors release firmware updates to correct security flaws, enhance stability, and ensure compatibility with updated security protocols. " (CCST Cybersecurity, Endpoint Security Concepts, System and Firmware Maintenance section, Cisco Networking Academy)
* A is partially true but not the primary security reason for updates.
* B is incorrect because firmware is not part of the OS kernel; it's embedded in the hardware.
* C is correct: patching vulnerabilities in firmware is essential for endpoint protection.
* D may occur as a side benefit, but it's not the main reason from a cybersecurity perspective.
65. Frage
A threat actor sets up a rogue access point (AP) at a local cafe. The rogue AP captures traffic and then forwards the traffic to the cafe AP.
Which type of attack does this scenario describe?
Antwort: A
Begründung:
The CCST Cybersecurity Study Guide describes a man-in-the-middle (MITM) attack as an attack where the adversary secretly intercepts and possibly alters communications between two parties, making them believe they are communicating directly. A rogue AP configured to pass traffic through itself before sending it on is a classic wireless MITM method.
" In a MITM attack, the attacker places themselves between the sender and receiver, intercepting and possibly altering data in transit. Rogue access points can facilitate MITM attacks in wireless environments. " (CCST Cybersecurity, Basic Network Security Concepts, Wireless Threats section, Cisco Networking Academy)
* A is incorrect: Reconnaissance is information gathering, not active interception.
* B is correct: This is a wireless MITM attack.
* C is incorrect: DDoS aims to overwhelm a service, not intercept data.
* D is incorrect: Ransomware encrypts data for extortion.
66. Frage
What does hashing provide for data communication?
Antwort: B
Begründung:
Hashing is a cryptographic technique that converts input data into a fixed-length output called a hash value or message digest.
Cryptographic hash functions are commonly used to verify that information has not been modified during storage or transmission.
For example, a sender calculates a hash value for a file before transferring it. The receiver independently calculates the hash of the received file and compares the two values.
If the hash values match, this provides evidence that the data has not changed, assuming a secure hash function and a trustworthy reference hash.
Key characteristics of cryptographic hashing:
* Deterministic: The same input produces the same hash output.
* Fixed-length output: The hash has a defined size regardless of input length.
* One-way operation: Secure hash functions are designed to make recovering the original input computationally infeasible.
* Collision resistance: It should be computationally infeasible to find two different inputs producing the same hash.
Why the other options are incorrect:
* A. Data non-repudiation: Typically requires digital signatures and supporting identity and key- management mechanisms. Hashing alone does not provide non-repudiation.
* B. Origin authentication: Requires an authentication mechanism such as a message authentication code (MAC) or digital signature. A plain hash cannot establish the sender ' s identity.
* C. Data encryption: Encryption protects confidentiality and can be reversed with the appropriate decryption key. Hashing is not encryption.
* D. Data integrity: Correct because cryptographic hashes can detect changes to data when compared against a trusted reference.
Important distinction: Hashing alone does not protect against an attacker replacing both the data and its hash.
Authenticated hashes, such as HMAC, or digital signatures address this limitation.
