Which cloud service model has the provider operate the application while the customer still manages areas such as identities, access, and data settings?
The maximum acceptable amount of data loss, measured in time, is the .
An organization is setting up production, development, and test workloads in the cloud. Which design best follows the recommended approach to environment separation?
- A
Place production, development, and test workloads on one unrestricted network for convenience.
- B
Separate production, development, and test environments and control communication between them.
- C
Allow all test systems to access production data and administrative interfaces by default.
- D
Use separate cloud accounts but permit unrestricted traffic between all workloads.
Fine-grained controls between individual workloads or services that reduce unnecessary east-west communication are called .
True or false: A report showing that backup jobs completed successfully demonstrates that the organization can restore its systems and data.
- A
True
- B
False
What is the name of the measure that sets the target time to restore a service after disruption?
A company hosts a public website and an internal database. Which network design best limits the paths an attacker could use if the web server is compromised?
- A
Place the web server on the database network and allow internet users to connect to both systems.
- B
Place the web server in a DMZ, allow only its required connection to an internal application service, and deny direct internet access to the database.
- C
Allow the web server to reach every internal system so it can support future features.
- D
Place the database in the DMZ and allow the web server and internet users unrestricted access to it.
A remote employee needs one internal application. Which access policy best applies zero-trust principles?
- A
Grant access to the entire internal network whenever a device has a corporate IP address.
- B
Trust any managed device automatically, without verifying its user or security state.
- C
Verify the user and device, consider relevant context, and grant access to the specific application required.
- D
Grant unrestricted access after a user connects through the corporate VPN.
A team is writing inter-zone firewall rules under a least-privilege policy. Select all practices that fit this policy.
- A
Permit only the required source, destination, protocol, and port for a documented purpose.
- B
Allow all traffic between internal zones because the systems are owned by the same organization.
- C
Deny other traffic by default where feasible and review rules to remove obsolete exceptions.
- D
Allow any source to connect to any destination as long as the protocol is approved.
A cloud team is reviewing controls for its management plane. Select all measures that improve security.
- A
Restrict inbound administrative traffic to the sources and services that are required.
- B
Allow all sources to reach administrative ports so administrators can connect from anywhere.
- C
Protect management interfaces and APIs, log their use, and monitor configuration changes.
- D
Assume the cloud provider is responsible for every security setting, including customer access permissions.
A service needs redundant network paths. Which design best reduces the risk that one failure will disable both paths?
- A
Use two network paths that depend on the same power source and router.
- B
Use alternate paths that do not share a single failure point capable of disabling both.
- C
Add a second service instance but connect both instances through the same sole network link.
- D
Duplicate hardware without checking for shared infrastructure dependencies.
A company needs to decide which systems should receive recovery resources first. What is the primary purpose of business-impact analysis in this decision?
- A
It determines which firewall rules can be removed without review.
- B
It proves that completed backup jobs can be restored successfully.
- C
It identifies critical services and helps prioritize recovery requirements.
- D
It replaces the need to define recovery strategies.
A facility needs business IT to exchange specified data with its operational technology (OT) network. A user workstation on business IT is later compromised. Describe an architecture and traffic-control approach that allows the required exchange while limiting the attacker's ability to reach OT systems.
An organization hosts a public website and an internal database. Which design best limits the paths an attacker could use if the web server is compromised?
- A
Place the web server on the database network and allow it to connect to any internal host.
- B
Place the web server in a DMZ, permit only its required connection to an internal application service, and deny direct internet access to the database.
- C
Allow internet users to connect to the database, but require the web server to use a VPN.
- D
Place the web server and database in the DMZ and rely on their separate hostnames to limit access.
An application server needs to query a database, but user workstations do not. Which firewall policy best applies least privilege?
- A
Allow every internal device to reach the database, but block internet hosts.
- B
Allow user workstations to reach the database on any port, but limit application servers to one port.
- C
Allow the application server to reach the database on its required service port, and block direct database connections from user workstations and internet hosts.
- D
Allow all traffic between internal network segments, and rely on VLANs to restrict database access.
A remote employee passes MFA on a managed device that meets security requirements. Which access decision best reflects zero-trust principles?
- A
Verify the user and managed device, then grant access to the specific application required.
- B
Grant access to the entire internal network because the employee passed MFA.
- C
Trust the employee's device because it is organization-owned, and check identity only at login.
- D
Allow unrestricted access to internal resources after the employee connects through the VPN.
A successful backup job by itself demonstrates that the backed-up data can be restored.
- A
True
- B
False
Which recovery measure sets the target time to restore a service? Enter its acronym.
What is the term for applying fine-grained network controls between individual workloads or services to reduce unnecessary east-west communication?
