Exam 350-901 topic 1 question 87 discussion

Correct answers: A & B https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9300-series-switches/white-paper-c87-742415.html https://www.ciscolive.com/c/dam/r/ciscolive/emea/docs/2019/pdf/BRKARC-2035.pdf

A and B are correct [..] applications must reside in one of the external Solid State Drive (SSD) storage options (USB 3.0 or M2 SATA), depending on the specific Cisco Catalyst 9000 platforms. Applications have no access to the internal device flash storage, which is reserved for Cisco IOS XE to protect its integrity. The M2 Sata can be internal or external SSD. https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9300-series-switches/white-paper-c87-742415.html https://www.ciscolive.com/c/dam/r/ciscolive/emea/docs/2019/pdf/BRKARC-2035.pdf

I agree, correct answers are A and B.

From here https://www.cisco.com/c/dam/en/us/td/docs/security/cyber_vision/Cisco_Cyber_Vision_Network_Sensor_Installation_Guide_for_Cisco_IE3400_and_Catalyst_9300_3_1_1.pdf The SD Card is nly supported on the 3400 and for the 9300 it states a SSD to be plugged in. The questions asks on a 9000 series. On a 9400 the storage plugs into the supervisor card. https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9400-series-switches/nb-06-cat9400-ser-sup-eng-data-sheet-cte-en.pdf. on the 9500 it appears external https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9500-series-switches/nb-06-cat9500-ser-data-sheet-cte-en.html. On 9600 its on the supervisor https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9600-series-switches/nb-06-cat9600-series-data-sheet-cte-en.html. Appears those switches that are modular are on the supervisor card itself and those that are stackable are external SSD. Given that it appears A and B is correct.

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/hardware/install/b_c9300_hig/b_c9300_hig_chapter_01010.html "SSD-120G provides an extra 120GB of storage for application hosting."

A & B are the rigth answers here!!

Agree with A & B Applications must reside in one of the external Solid State Drive (SSD) storage options (USB 3.0 or M2 SATA). M2 SATA can be internal or external SSD. https://www.ciscolive.com/c/dam/r/ciscolive/emea/docs/2019/pdf/BRKARC-2035.pdf

It's A and D. "Moreover, applications must reside in one of the external Solid State Drive (SSD) storage options (USB 3.0 or M2 SATA), depending on the specific Cisco Catalyst 9000 platforms.", so only EXTERNAL options are available and Cisco Catalyst 9300 has an SD-CARD slot that can be formatted as EXT4 too: https://www.cisco.com/c/dam/en/us/td/docs/security/cyber_vision/Cisco_Cyber_Vision_Network_Sensor_Installation_Guide_for_Cisco_IE3400_and_Catalyst_9300_3_1_1.pdf

"When using a back-panel USB or an M2 SATA drive for application hosting, the storage medium should be formatted as an ext4 filesystem."

Agree with 'A & B'
