You have configured a content-filtering firewall for traffic leaving a cloud virtual network. To which layer of the OSI model does this type of firewall apply? A. 2 B. 3 C. 4 D. 7

D. 7 --- D. Layer 7 (the application layer) of the OSI model relates to high-level protocols, meaning all packet headers and packet payloads can be examined, as opposed to a layer 4 packet filtering firewall, which can base decisions only on the fields present in packet headers. As a result, layer 7 firewall solutions tend to be more expensive than layer 4 firewall solutions. A, B, and C are incorrect. Layer 2 is the OSI data link layer, which is concerned with how transmissions are placed on the network medium. Layer 3 focuses on IP addressing and routing, and layer 4 is responsible for packet transport and delivery.

Create containers only from anonymous public repositories. D. Create containers only from private repositories.

D. Create containers only from private repositories. --- A containerized application decouples an application or application component (microservice) from other components or operating system dependencies. A container is a runtime version of a container image and consists of application files and configuration settings but not the OS; the underlying host OS that is already running is used instead. Hosting images in a private repository provides the ability to control which images are used to launch containers, thus enhancing security.

Invoked snapshots will have fewer patch updates than the currently running virtual machine.

D. Invoked snapshots will have fewer patch updates than the currently running virtual machine. --- D. Reverting a running virtual machine to an older snapshot could mean going back to a point in time before critical patches or virus scanning updates were applied, thus rendering your virtual machine vulnerable.

You must control network traffic flow to specific Amazon Web Services (AWS) virtual machines. What should you configure? A. Network ACL B. Amazon machine image C. Elastic IP address D. Security group

D. Security group --- An AWS security group contains a list of rules that allow traffic into or out of specific virtual machines (called EC2 instances in AWS).

Which protocol has the data origin authentication and data integrity protection feature? SMTP DNSSEC IMAP FTP

DNSSEC --- DNS attacks can be thwarted by using Domain Name System Security Extensions (DNSSEC). DNSSEC adds additional resource records (these records define the data types being used) and message header information, which can be used to verify that the requested data has not been altered in transmission. DNSSEC essentially adds two important features to the DNS protocol: data origin authentication allows a resolver to verify that the data it received actually came from the zone from which it claims to have originated, and data integrity protection proves the data has not been modified in transit since it was originally signed by the zone owner with the zone's private key.

In an interview, you are provided the following statements regarding secure protocols. Which of the following should you identify as correct? X.500 Lite is an open protocol, so applications don't need to worry about the type of server hosting the directory. POP3 is a remote email storage service responsible for incoming email, while IMAP is a store-and-forward service for incoming email. SNMPv1 uses community strings that support authentication, while SNMPv3 uses community strings that support encryption. Secure FTP (SFTP) uses SSL or TLS to encrypt commands, while FTP Secure (FTPS) is an entire protocol itself.

Which of the following is NOT correct about containers? a. Containers require a full OS whenever APIs cannot be used. b. Containers include components like binary files and libraries. c. Containers reduce the necessary hard drive storage space to function. d. Containers start more quickly.

a. Containers require a full OS whenever APIs cannot be used. --- A container, on the other hand, holds only the necessary OS components (such as binary files and libraries) that are needed for that specific application to run. And in some instances, containers can even share binary files and libraries. This not only reduces the necessary hard drive storage space and random access memory (RAM) needed but also allows for containers to start more quickly because the entire operating system does not have to be started. Containers can be easily moved from one computer to another.

Which of the following will NOT protect a container? a. Eliminate APIs. b. Use reduced-visibility images to limit the risk of a compromise. c. Use a hardened OS. d. Only use containers in a protected cloud environment.
