NEW QUESTION 11

You are configuring a 4-node AFF A400 ONTAP 9.8 cluster. The data center switches have limited ports, and you are given one 10-Gigabit Ethernet port per node for external access.
In this scenario, which three protocols share the same physical port? (Choose three)

• A. NVMe/FC
• B. ISCSI
• C. FCoE
• D. Snapmirror
• E. FC

Answer: BCD

Explanation:
If we have only ethernet switches available, we can only enable protocols over ethernet such as FCoE, ISCSI and Snapmirror.
NVMe/FC and FC need a SAN Fabric switch to work.

NEW QUESTION 12

scenario, what should be identical within the HA pair?

• A. FCP port MTU size
• B. FCP Port
• C. FCP port names
• D. FCP port LIF WWNN-based zoning

NEW QUESTION 13

You have deployed an AFF 400 systems for ISCSI workloads and want to ensure maximum performance to the hosts.
In this scenario, which two steps should be configured? (Choose two)

• A. Enable Jumbo frames on the network switch
• B. Enable Jumbo frames on the LIF
• C. Enable Jumbo frames on the broadcast domain
• D. Enable Jumbo frames on the IPspace

Answer: AC

Explanation:
Changing the Network port settings at the broadcast domain level will change all ports in that broadcast domain sequentially, or one at the time. This will only cause a disruption if the port is a single point of
failure.
Enable jumbo frames (typically MTU of 9000).All devices in the data path, including initiators, targets, and switches, must support jumbo frames. Otherwise, enabling jumbo frames actually reduces network
performance substantially.

NEW QUESTION 18

You have a 100GB volume with the space guarantee set to volume, This volume contains two space reserved 20 GB LUNs. Both LUNs are at 50% use. You then create a snapshot copy of the volume. No
modifications were performed since the snapshot copy was completed, and all actions were performed using the CLI. In this scenario, how much free space does the volume have?

• A. 60 GB
• B. 20 GB
• C. 40 GB
• D. 80 GB

Answer: A

Explanation:
Both LUN created are inheriting the space reserved parameter from its volume parent, so both LUNs are thick provisioned using 20 GB each one of them and the snapshots have not increased because
there has not been any changes since their creation 100GB - 20 GB - 20GB
