Question 1 of 138
Which method is a TCP/IP-based protocol for establishing and managing connections between IP-based storage devices, hosts, and clients?
Correct Answer: C

iSCSI (Internet Small Computer Systems Interface) is a TCP/IP-based protocol used for establishing and managing connections between IP-based storage devices, hosts, and clients. iSCSI allows data transfer over intranets and can be used to manage storage over long distances. Unlike other protocols like FCIP (Fibre Channel over IP), iFCP (Internet Fibre Channel Protocol), and FCoE (Fibre Channel over Ethernet), iSCSI specifically leverages TCP/IP for these connections and management, making it the correct answer.

Question 2 of 138
Which method does FCIP use to enable connectivity of geographically distributed Fibre Channel SANs over IP?
Correct Answer: B

FCIP (Fibre Channel over IP) utilizes tunneling to enable connectivity of geographically distributed Fibre Channel SANs over IP networks. Tunneling allows encapsulating Fibre Channel frames within IP packets, permitting the Fibre Channel traffic to be transmitted across standard IP networks seamlessly.

Question 3 of 138
Which important feature on the front end is provided to the clients by multiple servers that access the same storage devices across the SAN?
Correct Answer: B

When multiple servers access the same storage devices across a Storage Area Network (SAN), the key feature provided is redundancy. This means that if one server fails, another can take over without loss of access to data, ensuring continuous operation and reliability for the clients.

Question 4 of 138
The Ethernet specification details several different fiber optic media types. What is the wire transmission speed for 100BASE-FX Ethernet?
Correct Answer: B

The Ethernet specification for 100BASE-FX refers to Fast Ethernet over fiber optic cables, which has a wire transmission speed of 100 Mb/s. This is consistent with the naming convention where '100' refers to the speed in megabits per second and 'BASE-FX' indicates baseband signaling over fiber optic media.

Question 5 of 138
Which fiber optic cable type is used most often with a Subscriber connector?
Correct Answer: D

The most common fiber optic cable type used with a Subscriber connector (SC) is multi-mode. Multi-mode fibers have a larger core allowing multiple modes of light to propagate, making them well-suited for short distance communications often required in network connections using SC connectors.
