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

Agree with 'A & 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 only supported on the 3400 and for the 9300 it says an SSD has to be plugged in. The question asks about 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 looks 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. It seems those switches that are modular are on the supervisor card itself and those that are stackable are external SSD. Given that, A and B is correct.

I agree, the correct answers are A and B.

Selected Answer: AB The correct answers are 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

"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. Applications have no access to the internal device flash storage, which is reserved for Cisco IOS XE to protect its integrity"

"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 Applications must stay 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

A & B are the rigth answers here!!

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."

Selected Answer: AB A and B are right [..] applications must live 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
