8.1.9 Corporate and Datacenter Networks
Which of the following BEST defines a SAN?
A block-level storage network A storage attached network (SAN) is a block-level storage solution built for speed and ease of sharing.
What are the three layers of an SDN?
Application, Control, and Infrastructure
Run the iSCSI Initiator to connect to an iSCSI target defined somewhere on the SAN fabric. You can also use this utility to define iSCSI security settings, including CHAP and IPsec.
Controllers Controllers are what operate at the control plane and run an SDN.
Brett has been tasked with creating a new SAN. The company currently has Gigabit internet, and his CTO wants to use Fibre Channel over Ethernet (FCoE) in the SAN. Brett tells the CTO that this will not work. Which of the following BEST describes the problem?
Fibre Channel over Ethernet requires 10 Gigabit internet. The problem is that FCoE requires 10 Gigabit internet.
What BEST describes the designed purpose of InfiniBand?
High-performance supercomputers InfiniBand was designed for high-performance supercomputers.
Which of the following are the components of a SAN?
Hosts, storage, and SAN fabric EXPLANATION Storage attached networks have hosts (hypervisors), storage on the target servers, and SAN fabric that consists of the cabling.
Which option BEST describes the third layer in the SDN architecture?
Infrastructure The third layer of SDN is the Infrastructure, or Physical, layer. This is where the network hardware is located.
You manage a network with three dedicated storage devices, as shown in the diagram. Users on the network see only a single file server. Which network-based storage technology is being used?
NAS with clustering Explanation: A NAS device is an appliance that's dedicated to file storage. With clustering, multiple NAS devices are grouped together to provide a degree of fault tolerance. To users on the network, the cluster appears as a single file server. Without clustering, the NAS devices would appear as three separate file servers.
Arrange the Fibre Channel (FC) SAN implementation tasks in the order they should be performed to build a redundant FC SAN.
Step 1 Install two Fiber Channel host bus adapters in each server that will access the shared storage on the SAN. Step 2 Deploy two FC switches. Step 3 Using fiber optic cables, connect each server to each FC switch by connecting one FC HBA to one FC switch and the other FC HBA to the other FC switch. Step 4 Deploy the shared storage devices, such as an external RAID device containing multiple hard disk drives and two FC HBAs. Step 5 Using fiber optic cables, connect each storage device to each FC switch by connecting one FC HBA to one FC switch and the other FC HBA to the other FC switch.
You are in the process of configuring an iSCSI storage area network (SAN) for your network. You want to configure a Windows Server system to connect to an iSCSI target defined on a different server system. You also need to define iSCSI security settings, including CHAP and IPsec. Which tool should you use?
iSCSI Initiator Run the iSCSI Initiator to connect to an iSCSI target defined somewhere on the SAN fabric. You can also use this utility to define iSCSI security settings, including CHAP and IPsec.
