Question 6

Click the Exhibit button.

The exhibit shows a Windows 2019 server with two FC HBAs using ALUA.

How many paths to LUN1 are active/optimized? (Choose the best answer.)

    Correct Answer: B

    In a configuration with a Windows 2019 server using ALUA (Asymmetric Logical Unit Access) and two Fibre Channel HBAs connected through dual FC switches to a dual-controller setup (Nodes N1 and N2), the number of active/optimized paths to a LUN is determined by the controller that owns the LUN. In the given diagram, the LUN is hosted on N1, and each HBA from the host can reach N1 through one of the FC switches. This creates two active/optimized paths directly from the host to N1. Therefore, the correct answer is 2.

Discussion
pwnzalolOption: B

https://youtu.be/tKeMF7LlfAQ At 06:25 he explains the active/opt paths and non-opt. paths. According to this video it should be 2 Optimized Paths. From the host to FC Switch 1 plus FC cabeling to the Node is the first Optimized Path. The second to Fibre Channel Switch B to the Node.

TorusOption: B

For this topology, the answer should be B (2 optimized paths), as the Window host is directly connected to each FC Switch and each switch is connected to Node 1 that hosts the LUN.

Agree, B is the answer

Metasploit

B. 2 ALUA optimized paths would terminate on the node that owns the LUN. From the diagram I assume it is node1. Optimized paths: Host-->FC1-->Node1(LUN owner) Host-->FC2-->Node1(LUN owner)

PatrickBOption: D

answer is D

safodzOption: C

I thin k 1 is correct answer it says Optimized Active only 01 coud have this condition

slizlaOption: B

There are two active paths from host to node1 LIFs who owns the LUN so there are two optimized paths to the LUN and two non optimized paths from node2 LIFs. Answer is B https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-concepts%2FGUID-9D007B6F-979F-4A75-A744-5F54C136AD6C.html

Sorry, the answer is D. You must count paths through HA between nodes as well.

skeef7Option: C

I think answer is C. Because we have 2 paths optimized and nonoptimized

VindiOption: B

I think this is 2 as there are 4 all together 2 optimised and 2 non optimised
