質問 2：
Refer to the exhibits.

A consultant is trying to test port failover on the node shown in the first exhibit. A continuous ping test is performed to the host. The consultant shuts down one of the links, after which the host ping request times out.

質問 3：
A consultant is attempting to deploy an AHV cluster, but Foundation did not discover any factory-imaged nodes. The consultant then uses the crash cart script to configure all IP addresses manually.
What step is required for the consultant to continue cluster creation?
A. Create a new cluster, bypassing discovery, by using the flag --skip_discovery.
B. Create a new cluster by using the flag --multicast_static-group.
C. Remove the VLAN igmp unknown-mcast-flood option from the switch configuration.
D. Use the cluster -s IP1, IP2, IP3, IPn create command to create the cluster.

質問 8：
An administrator needs to create and start five new VMs for a Data Analytics Project (OLAP). The VM Profile is as follows:
* vCPU:4
* vRAM: 64 GB
* vDisk: 1.5 TB
Each of the four nodes of the Nutanix cluster has the following:
* 24 vCPU. 20% overall usage
* 192 GB RAM, 60% overall usage
* 2xl920GBSSD
* 4x 2 TB HDD
At cluster level, there is a single RF2 container that is 30% utilized and has an extent store capacity of 13.5 TB.
Which component requires administrator attention?
A. Storage, because the capacity is not enough to create VMs.
B. Physical RAM, because it is not enough to power on all of the new VMs.
C. Physical Cores, because they are not enough to power on all of the new VMs.
D. Flash Tier because it is not enough to accommodate the workloads.
正解：B

質問 9：
A consultant has been tasked with increasing security on a Nutanix cluster by disabling password authentication when accessing the CVM and AHV hosts and instead moving to key-based SSH.
What is the easiest way for the consultant to meet these requirements?
A. Restrict access with User Management in Prism.
B. Enable STlGs via command line on SSH to a CVM.
C. Configure LDAP authentication through a secure server.
