   Which option is an example of a North-South traffic flow?

   • ALateral movement within a cloud or data center
   • BAn internal three-tier application
   • CClient-server interactions that cross the edge perimeter
   • DTraffic between an internal server and internal user

   Show answer

   Answer: C

   Explanation

   pg.208 North-south refers to data packets that move in and out of the virtualized environment from the host network or a corresponding traditional data center. North-south traffic is secured by one or more physical form factor perimeter edge firewalls.

   • DMirai

   Show answer

   Answer: A

   Explanation

   Should be A, as per study guide, page 62: "The main problem with this approach is that it requires a potential victim to stumble on the access point and connect. The attacker can’t easily target a specific victim, because the attack depends on the victim initiating the connection."

   Which option describes the `selective network security virtualization` phase of incrementally transforming data centers?

   • Aduring the selective network security virtualization phase, all intra-host communication paths are strictly controlled
   • Bduring the selective network security virtualization phase, all intra-host traffic is forwarded to a Web proxy server
   • Cduring the selective network security virtualization phase, all intra-host traffic is encapsulated and encrypted using the IPSEC protocol
   • Dduring the selective network security virtualization phase, all intra-host traffic is load balanced

   Show answer

   Answer: A

   Explanation

   pg.212 Selective network security virtualization: Intra-host communications and live migrations are architected at this phase. All intra-host communication paths are strictly controlled to ensure that traffic between VMs at different trust levels is intermediated either by an on-box, virtual security appliance or by an off-box, physical security appliance.

   Which TCP/IP sub-protocol operates at the Layer7 of the OSI model?

   • AUDP
   • BMAC
   • CSNMP
   • DNFS

   Show answer

   Answer: C

   Explanation

   ● Network (Layer 3 or L3): This layer provides routing and related functions that enable data to be transported between systems on the same network or on interconnected networks. Routing protocols are defined at this layer. Logical addressing of devices on the network is accomplished at this layer using routed protocols such as Internet Protocol (IP). Routers operate at the Network layer of the OSI model. ● Data Link (Layer 2): This layer ensures that messages are delivered to the proper device across a physical network link. ● Physical (Layer 1 or L1): This layer sends and receives bits across the network medium (cabling or wireless links) from one device to another. It specifies the electrical, mechanical, and functional requirements of the network, including network topology, cabling and connectors, and interface types, and the process for converting bits to electrical (or light) signals that can be transmitted across the physical medium.
