What’s the first step to diagnose the issue?
a) Reinstall the CRM application on all workstations.
b) Run a traceroute to identify network bottlenecks.
c) Upgrade all workstations’ RAM.
d) Switch to a different CRM provider.
Question 11
Scenario: Your company is adopting a zero-trust security model. You need to ensure that all devices accessing the network are verified before granting access.
What should you implement to enforce device verification?
a) Allow all devices to connect without checks.
b) Deploy a Network Access Control (NAC) solution.
c) Disable multi-factor authentication for simplicity.
d) Use a single password for all devices.
Question 12
Scenario: You’re managing a hybrid cloud environment with on-premises servers and AWS EC2 instances. An EC2 instance is unreachable due to a misconfigured security group.
What should you check to restore access to the EC2 instance?
a) Verify the security group’s inbound rules for allowed ports.
b) Delete and recreate the EC2 instance.
c) Disable the AWS firewall entirely.
d) Reinstall the operating system on the instance.

Explanations
Question 1: Correct Answer: b) Check the Azure AD Connect synchronization status.
Why b? Azure AD Connect synchronizes on-premises AD with Azure AD, and sync issues can prevent users from using domain credentials in cloud apps.
Why not a? Resetting passwords is disruptive and doesn’t address sync issues.
Why not c? Disabling on-premises AD breaks authentication entirely.
Why not d? Reinstalling applications is irrelevant to identity sync problems.
Question 2: Correct Answer: a) Verify the GPO’s link order and enforcement settings.
Why a? GPO link order or enforcement settings (e.g., blocked inheritance) can prevent application, and checking these ensures the GPO is applied correctly.
Why not b? Deleting the OU is destructive and unnecessary.
Why not c? Applying to the entire domain affects unintended users.
Why not d? Restarting computers doesn’t fix GPO configuration issues.
Question 3: Correct Answer: b) Implement account lockout policies and IP-based rate limiting.
Why b? Lockout policies block brute-force attempts, and rate limiting prevents excessive requests, protecting the server while allowing legitimate access.
Why not a? Shutting down the server disrupts all users.
Why not c? Removing the admin panel may break functionality.
Why not d? Allowing all attempts risks further compromise.
Question 4: Correct Answer: a) Edit the GRUB configuration file and update the bootloader.
Why a? Modifying GRUB ensures kernel parameters persist across reboots, a standard Linux practice for performance tuning.
Why not b? Reinstalling the OS is excessive and loses configurations.
Why not c? Manual application is unsustainable.
Why not d? Disabling the boot process renders the server unusable.
Question 5: Correct Answer: a) Upgrade the NAS firmware and enable caching.
Why a? Firmware updates can improve performance, and caching reduces access times during peak usage.
Why not b? Disconnecting the NAS disrupts users.
Why not c? Reducing files doesn’t address performance bottlenecks.
Why not d? Switching to cloud storage is costly and unnecessary.
Question 6: Correct Answer: b) Install and configure a syslog agent or forwarder.
Why b? Syslog agents forward server logs to the SIEM, enabling centralized monitoring and analysis.
Why not a? Disabling firewalls risks security without enabling log forwarding.
Why not c? Rebooting doesn’t configure log forwarding.
Why not d? Manual copying is inefficient and unscalable.
Question 7: Correct Answer: b) Resize the VM’s virtual disk or enable dynamic allocation.
Why b? Resizing or enabling dynamic disks optimizes space usage, freeing resources for other VMs without downtime.
Why not a? Deleting the VM is disruptive and unnecessary.
Why not c? Adding disks requires hardware changes and may not solve the issue.
Why not d? Disabling the network adapter doesn’t address disk usage.
Question 8: Correct Answer: a) Run the script with elevated privileges or a service account.
Why a? Elevated privileges or a service account provide the necessary permissions for the script to execute maintenance tasks.
Why not b? Disabling security policies risks system vulnerability.
Why not c? Rewriting the script is unnecessary if permissions can be fixed.
Why not d? Manual execution defeats the purpose of automation.
Question 9: Correct Answer: b) Configure load balancing or split tunneling.
Why b? Load balancing distributes VPN traffic, and split tunneling reduces server load by routing non-essential traffic directly, improving performance.
Why not a? Increasing bandwidth limits doesn’t address server overload.
Why not c? Disabling encryption reduces security without guaranteed performance gains.
Why not d? Restricting access limits functionality for users.
Question 10: Correct Answer: b) Run a traceroute to identify network bottlenecks.
Why b? Traceroute reveals latency or routing issues between workstations and the cloud, pinpointing network bottlenecks.
Why not a? Reinstalling the CRM doesn’t address network issues.
Why not c? Upgrading RAM is unrelated to network latency.
Why not d? Switching providers is premature without diagnosis.
Question 11: Correct Answer: b) Deploy a Network Access Control (NAC) solution.
Why b? NAC verifies device compliance (e.g., security patches, antivirus) before granting network access, aligning with zero-trust principles.
Why not a? Allowing all devices violates zero-trust security.
Why not c? Disabling MFA weakens authentication security.
Why not d? A single password undermines device-specific verification.
Question 12: Correct Answer: a) Verify the security group’s inbound rules for allowed ports.
Why a? Misconfigured security group rules (e.g., blocked ports) can prevent access to EC2 instances, and checking these restores connectivity.
Why not b? Deleting the instance is destructive and unnecessary.
Why not c? Disabling the firewall exposes the instance to attacks.
Why not d? Reinstalling the OS doesn’t fix network configuration issues.
