SY0-701 Exam Dumps and Practice Questions

The Online Certificate Status Protocol (OCSP) is a technology designed to check the revocation status of digital certificates in real-time without requiring the client to download entire revocation lists. Unlike Certificate Revocation Lists (CRLs), which are periodically updated and can be large, OCSP queries an OCSP responder to receive the status of a specific certificate.

OCSP is considered passive verification because it allows clients to check a certificate's current validity status on-demand without maintaining local copies of revocation data. The OCSP responder returns whether the certificate is valid, revoked, or expired.

Trusted Platform Module (TPM) is hardware for secure key storage, and Certificate Signing Request (CSR) is a request for certificate issuance; neither is used for verifying certificate expiration status.

The differences and roles of OCSP and CRLs are thoroughly covered in the Cryptography and PKI chapter of the SY0-701, where OCSP is highlighted as the more efficient and real-time method to verify certificate status passively6:Chapter 7CompTIA Security+ Study Guide.

The best answer is B. It replaces the original data with reference values that do not hold exploitable meaning.

Tokenization protects sensitive data by substituting the original value with a token, which is a non-sensitive reference value. The token has no meaningful value to an attacker if it is intercepted or exposed. The real sensitive data is stored separately in a protected system, often called a token vault.

This is commonly used for:

payment card data

personally identifiable information

sensitive customer records

Why the other options are incorrect:

A . It permanently deletes sensitive information from production systems.Tokenization does not necessarily delete the original data permanently. It replaces exposed operational use with tokens while the real data is retained securely elsewhere.

C . It stores sensitive data across multiple cloud environments to prevent data loss.This is unrelated to tokenization.

D . It conceals data by converting it into unreadable ciphertext using symmetric encryption.This describes encryption, not tokenization.

From a SY0-701 perspective, tokenization reduces exposure by replacing real sensitive values with non-exploitable substitutes, so B is correct.

The best answer is B. Updating default credentials and applying network segmentation.

IoT devices often present increased security risk because they may have weak default settings, limited security features, and persistent network connectivity. Two of the most effective ways to reduce this risk are:

Updating default credentialsMany IoT devices come with default usernames and passwords that are widely known or easy to guess. Leaving default credentials unchanged creates a major security weakness.

Applying network segmentationSegmenting IoT devices onto a separate network or VLAN limits their ability to interact with critical corporate systems. If one device is compromised, segmentation helps contain the threat and reduces lateral movement.

Why the other options are incorrect:

A . Assigning static IP addresses to the devicesStatic IP addresses may help with management and inventory, but they do not significantly reduce the core security risk.

C . Connecting the devices to the guest Wi-Fi to prevent interactions with corporate ITThis may seem helpful, but guest Wi-Fi is typically designed for temporary user access, not secured management of business IoT systems. It is not the best practice compared with a properly segmented and controlled IoT network.

D . Allowing the vendor to have remote access for day-to-day managementRoutine vendor remote access can increase risk if not tightly controlled. Third-party access should be limited, monitored, and secured, not broadly allowed as a default control.

From the SY0-701 perspective, IoT security commonly emphasizes changing insecure defaults, restricting access, segmentation, and reducing exposure. Therefore, B is the strongest and most complete answer.

The first stage in the incident response process is Detection (also called Identification).

The incident response process typically follows these stages:

1. Detection/Identification: Recognizing that an incident has occurred through alerts, logs, user reports, or monitoring systems
2. Containment: Stopping the attack and preventing further damage (short-term and long-term)
3. Eradication: Removing the attacker's presence from systems
4. Recovery: Restoring systems to normal operations
5. Post-Incident Activities: Learning from the incident and improving security

Detection stage activities include:

• Monitoring security tools (SIEM, IDS/IPS, antivirus)
• Analyzing alerts and anomalies
• Receiving and triaging incident reports
• Determining the scope and severity of the incident
• Activating the incident response team

Without proper detection, organizations cannot respond to incidents. Therefore, detection is the critical first step that triggers the entire incident response process.

Counterfeit hardware is hardware that is built or modified without the authorization of the original equipment manufacturer (OEM).It can pose serious risks to network quality, performance, safety, and reliability12.Counterfeit hardware can also contain malicious components that can compromise the security of the network and the data that flows through it3. To address the risks associated with procuring counterfeit hardware, a company should conduct a thorough analysis of the supply chain, which is the network of entities involved in the production, distribution, and delivery of the hardware. By analyzing the supply chain, the company can verify the origin, authenticity, and integrity of the hardware, and identify any potential sources of counterfeit or tampered products. A thorough analysis of the supply chain can include the following steps:

Establishing a trusted relationship with the OEM and authorized resellers

Requesting documentation and certification of the hardware from the OEM or authorized resellers

Inspecting the hardware for any signs of tampering, such as mismatched labels, serial numbers, or components

Testing the hardware for functionality, performance, and security

Implementing a tracking system to monitor the hardware throughout its lifecycle
