質問 # 78
Which security option should be implemented to ensure that all intra-cluster communication is secured?
正解：A
解説：
Network Encryption is the security control directed at protecting data while it traverses the network between Nutanix cluster components. It provides cryptographic confidentiality and integrity for supported intra-cluster traffic, preventing captured traffic from being interpreted or modified without detection. In AOS 7.5, the documented intra-cluster data-in-transit encryption capability specifically covers Stargate storage traffic.
Accordingly, the examination wording should be interpreted as asking which option cryptographically secures intra-cluster communications, for which Network Encryption is the only valid choice.
Network Segmentation serves a different purpose. It isolates traffic categories-such as management, backplane, or replication traffic-onto separate networks. Segmentation can reduce exposure and limit broadcast or failure domains, but isolated traffic is not necessarily encrypted. Cluster Lockdown restricts administrative access, particularly access paths involving hosts and Controller VMs; it does not encrypt packets moving between cluster services. "vSwitch Lockdown" is not the relevant Nutanix data-in-transit security mechanism.
The decisive distinction is therefore encryption versus isolation or access restriction. If the requirement is that intercepted traffic must remain unreadable, an encryption capability is required. Segmentation may complement that control, but cannot replace it.

Which protocols does the Network Visualizer leverage to discover and display network connections and statistics?
正解：A
解説：
Nutanix Network Visualizer uses Link Layer Discovery Protocol or Cisco Discovery Protocol to determine the relationship between an AHV host interface and the corresponding first-hop physical-switch port. It can then use configured SNMP access to retrieve additional switch, port and operational statistics. The combined protocol set in option C therefore enables both topology discovery and the display of useful physical-network information.
LLDP is vendor-neutral, while CDP is primarily associated with Cisco networking equipment. Either protocol can advertise the local port identity needed to construct the topology mapping. SNMP supplements that discovery by providing management-plane information obtained from supported switches. Nutanix documentation notes that when LLDP or CDP information is unavailable, SNMP data may be used to assist mapping, although complete and accurate visualization depends on supported devices and appropriate configuration.
BGP and OSPF exchange routing information; they are not the protocol set used by Network Visualizer for host-to-switch discovery. DHCP and PXE provide address allocation and network boot services. STP prevents Layer 2 loops, while VTP distributes VLAN information in certain Cisco environments.

What is the default time that a Nutanix cluster will run an LCM auto inventory and auto update?
正解：D
解説：
The default scheduled time for LCM automatic inventory and automatic update activity is 3:00 AM. This setting is used when Auto Inventory and Auto Update are enabled for a connected site. Administrators can modify the schedule when 3:00 AM does not align with the organization's operational or maintenance requirements.
Automatic inventory refreshes LCM's knowledge of installed software and firmware components and retrieves current update metadata from the configured Nutanix source. Nutanix also specifies that if an inventory operation has already completed within the preceding 12 hours, LCM can skip the scheduled auto- inventory because its component information remains sufficiently current. Automatic update in this setting applies to the supported automatically managed component-particularly Nutanix Cluster Check-rather than authorizing every available AOS, AHV, or firmware upgrade without administrator review.
The other answer choices do not represent the documented default. However, administrators should treat 3:00 AM as a configurable platform default rather than an assumed maintenance window. They must verify the configured schedule, time context, Internet connectivity, and update policy for the specific environment.

質問 # 81
LCM provides which two features for firmware and software updates? (Choose two.)
正解：A、C
解説：
Life Cycle Manager provides automatic dependency management and a one-click update workflow for supported Nutanix software and hardware firmware. LCM inventories the environment, identifies installed component versions, retrieves compatible update metadata, and evaluates dependencies between components before permitting an upgrade. This prevents administrators from manually determining the correct order for related AOS, AHV, NCC, Foundation, firmware, and platform updates.
Nutanix describes the LCM workflow as a one-click update because administrators can select eligible components and initiate an orchestrated upgrade through Prism. LCM then performs prechecks, stages packages, applies updates in the necessary sequence, and coordinates node maintenance while preserving cluster availability where supported.
A general rollback to the previous software or firmware version is not an LCM feature. Upgrades should therefore be treated as forward-moving maintenance operations that require validated backups, health checks, and compatibility review. Although LCM supports numerous qualified hardware platforms, option C is not the core feature being tested. Platform support depends on the hardware vendor, model, firmware bundle, and Nutanix compatibility requirements; it is not an unrestricted multi-platform update function.

質問 # 82
On an AHV host, what is the factory-configured default native Linux bridge?
正解：D
解説：
The factory configuration of an AHV host includes a native Linux bridge named virbr0. This bridge is separate from the Open vSwitch components used for normal AHV workload and infrastructure networking.
Administrators should preserve the factory-defined bridge unless a specific Nutanix procedure instructs otherwise.
The similarly named components in the other options serve different purposes. br0 is the factory-configured default Open vSwitch bridge. It contains the physical uplink interfaces and internal ports used by the AHV networking architecture. vs0 is the default AHV virtual-switch configuration associated with br0; it is a logical virtual-switch object rather than a native Linux bridge. ovsbr0 is not the factory-default bridge name in the documented AHV configuration.
This distinction is operationally important when interpreting commands such as ovs-vsctl, Linux bridge utilities, interface listings, or network-troubleshooting output. Confusing virbr0 with br0 can lead an administrator to modify the wrong networking component and potentially disrupt host, CVM, or guest connectivity. Nutanix documentation explicitly identifies the native Linux bridge as virbr0. Reference: AHV
