ISC Practice Test 6 — 10 Questions

Question 1

Which component in a Privileged Access Management (PAM) solution is responsible for 'Credential Rotation'?

Accepted Answer

The PAM Vault/Secret Manager.. The PAM vaulting component (e.g., CyberArk Vault, HashiCorp Vault) is responsible for automatically updating and rotating passwords on target systems based on defined policies.

Answer

The MFA provider.

Answer

The jump server.

Answer

The session recorder.

Question 2

Which THREE features are essential for a robust Privileged Access Management (PAM) architecture that adheres to the principle of least privilege?

Accepted Answer

Granular Role-Based Access Control (RBAC). Credential vaulting, session recording, and granular access delegation are core pillars of PAM.

Answer

Automatic network topology mapping

Answer

Public cloud storage for logs

Question 3

A security architect is designing an authentication flow for a distributed system. Which method provides the best defense against replay attacks?

Accepted Answer

Using short-lived tokens with nonces.. Using a nonce or a short-lived token with a timestamp ensures that each authentication request is unique and can only be processed once.

Answer

Using IP-based restriction.

Answer

Using long-lived API keys.

Answer

Enabling HTTPS for all traffic.

Question 4

You are architecting a solution to mitigate 'Token Theft' in a Zero Trust environment. Which mechanism binds a token to a specific client instance?

Accepted Answer

DPoP (Demonstrating Proof-of-Possession). DPoP (Demonstrating Proof-of-Possession) binds tokens to a private key held by the client, ensuring that even if a token is stolen, it cannot be used without the accompanying private key.

Answer

PKCE (Proof Key for Code Exchange)

Answer

Refresh Token Rotation

Answer

MFA step-up

Question 5

When deploying HashiCorp Vault for secrets management, you need to implement a 'Dynamic Secrets' architecture for database access. Which workflow is correct?

Accepted Answer

Vault requests a new user creation from the DB via a configured engine and returns those credentials to the client.. The dynamic secret workflow involves Vault generating unique, short-lived database credentials on-the-fly for every request, which are automatically revoked upon expiry.

Answer

Clients authenticate to the DB via Vault using LDAP delegation.

Answer

Vault retrieves static credentials from a PKI backend and rotates them.

Answer

Vault hashes existing database passwords and stores them in transit.

Question 6

What is the primary architectural purpose of implementing Just-in-Time (JIT) access?

Accepted Answer

To minimize the window of opportunity for attackers to exploit standing privileges.. JIT access reduces the attack surface by ensuring that high-privilege access is only active when needed, rather than remaining persistent.

Answer

To eliminate the need for an identity provider.

Answer

To increase user productivity by removing MFA requirements.

Answer

To automate user provisioning and deprovisioning.

Question 7

In a SAML 2.0 federation, an Identity Provider (IdP) is failing to authenticate users because the Service Provider (SP) cannot verify the assertion integrity. The SP requires the IdP to sign the assertion. What must be exchanged to solve this?

Accepted Answer

Exchange the IdP's public signing certificate. For the SP to verify the IdP's signature on an assertion, the SP must possess the IdP's public certificate.

Answer

Configure the SP to use the NameID format

Answer

Exchange the SP's private key with the IdP

Answer

Enable encrypted assertions using the SP's public key

Question 8

What is the purpose of 'Claims Transformation' in an Identity Provider?

Accepted Answer

To convert user attributes from one format to another.. Claims transformation allows the IdP to map or modify attributes from a source directory (like AD) into a format expected by the target application (SAML/OIDC).

Answer

To encrypt the entire user session.

Answer

To authenticate users against multiple directories simultaneously.

Answer

To store authentication logs in a central repository.

Question 9

Which THREE mechanisms are commonly used to secure the 'Authorization Code' in an OAuth 2.0 flow?

Accepted Answer

Implementing PKCE (Proof Key for Code Exchange).. HTTPS (transport security), PKCE (binding code to request), and short-lived tokens/codes are standard security measures.

Answer

Storing the code in a public client's local storage.

Answer

Sending the code in the URL fragment of a redirect.

Question 10

A company is migrating legacy workloads to Azure and requires host-based intrusion detection with file integrity monitoring (FIM) across hybrid environments. Which service provides this integrated capability?

Accepted Answer

Microsoft Defender for Servers. Microsoft Defender for Servers (part of Microsoft Defender for Cloud) provides the integrated FIM and endpoint protection features required for hybrid cloud/on-premises machines.

Answer

Azure Monitor

Answer

Network Watcher

Answer

Azure Bastion
