質問 # 13
A branch has Direct Internet Access enabled. Users can resolve DNS, but application traffic fails. You find that the internet speed test also fails to fetch the server list. Which two configurations should be checked first?
正解：C
解説：
The correct answer is A . Versa documentation for internet speed tests states that before running an internet speed test, administrators must verify WAN internet connectivity and verify that CGNAT is configured on the provider organization. It also states that administrators should verify that they can retrieve the list of predeployed internet speed-test servers. If an error occurs while fetching the server list, the documentation instructs administrators to check the CGNAT and DNS configurations and then click Fetch Server List again.
This aligns with the scenario because DNS resolution and internet breakout depend on correct DNS reachability, NAT translation, and routing through the internet-facing transport. Even if DNS appears partially functional, CGNAT misconfiguration can still prevent application or HTTP test traffic from completing properly.
OSPF, BGP MED, SNMP, syslog, VRRP, and DHCP may be important in other designs, but they are not the first items Versa identifies for a failed internet speed-test server-list fetch in a DIA context.

You need to quickly check interface administrative status, operational status, tenant ID, VRF, MAC address, and IP address on a VOS device. Which command should you use?
正解：A
解説：
The correct answer is A . Versa's handy CLI command reference lists show interfaces brief as the command used to view a list of interfaces along with their MAC addresses, operational and administrative status, tenant ID, VRF, and IP addresses. This is one of the first commands administrators run when validating device bring- up, staging interface assignment, WAN/LAN mapping, or whether a template applied interface addressing as expected.
For deeper interface troubleshooting, show interfaces detail provides additional information such as interface index, host interface, MTU, speed and duplex settings, RX/TX errors, and bridge information. However, for a quick overview of state and addressing across interfaces, show interfaces brief is the correct choice.
show system package-info identifies the running VOS software package. show system storage reports system storage resources. show coredumps shows generated core files. These are valuable operational commands, but they do not provide the requested interface status and addressing summary.
質問 # 15
Which two methods would be used to upgrade deployed VOS branch devices? (Choose two.)
正解：C、D
解説：
The correct answers are A and C . Versa supports upgrading deployed VOS branch devices either directly on the VOS appliance or centrally through Versa Director. The Director-based method is performed from the Administration > Appliances area: Versa documentation says to select one or more Controller nodes or VOS devices, click the Upgrade Selected Appliances icon, choose the software image package, and proceed with the appliance upgrade. The same upgrade procedure is referenced for remaining VOS branch devices, including the option to upgrade branches individually or all at once.
A CLI-based upgrade using a software .bin package is also a valid operational method when the image is copied to the device and installed locally, particularly for controlled or recovery-style maintenance.
Option B is not the best answer for already deployed branch upgrades because the Preferred Software Version field applies to zero-touch provisioning; Versa states that during ZTP, Director upgrades a branch to the preferred version if applicable. That setting influences onboarding behavior, not the normal upgrade workflow for already deployed branches. Option D is incorrect because System > Director Upgrade is used to upgrade the Versa Director node itself, not VOS branch appliances.
質問 # 16
Which two statements are true about the differences between a stateful firewall and a next-generation firewall (NGFW) in a Versa solution? (Choose two.)
正解：B、C
解説：
The correct answers are A and D . A Versa stateful firewall primarily enforces security by tracking connection state and matching packet/session information such as source, destination, zones, services, protocol, and L3/L4 attributes. Versa's CLI configuration guide shows stateful firewall access-policy match options for source and destination addresses, services, IP version, IP flags, DSCP, TTL, and also optional application and URL-category match fields when enhanced services are available.
A Versa NGFW extends this inspection model by adding deeper Layer 7 and UTM capabilities, such as IDS
/IPS, antivirus, URL filtering, file or data filtering, and application-aware enforcement. Versa's SD-WAN design guide specifically describes internet security using the Versa next-generation firewall with unified threat management features, including IDS/IPS and antivirus inspection for DIA traffic. Licensing is also a valid distinction: Versa's SD-WAN licensing overview describes NGFW features as part of solution tiers, so the availability of advanced security functions depends on the licensed tier or subscription
質問 # 17
You are troubleshooting a branch that cannot form SD-WAN overlay tunnels. The branch has WAN interfaces up, but you suspect remote endpoint objects were not learned. Which VSM command should you use to verify whether remote site objects were learned from BGP or from configuration?
正解：A
解説：
The correct answer is A . Versa data-path troubleshooting documentation gives a specific VSM control-plane workflow for checking SD-WAN tunnel objects. After connecting to the VSM daemon, administrators can use show vsm p2mp local-tunnel-sites 0 to inspect local site objects. To check whether remote site objects were learned from BGP or from configuration , Versa instructs administrators to issue show vsm p2mp tunnel-remote-endpoint tenant < tenant-id > on the VSM control plane.
This command is highly relevant when local WAN interfaces are operational, but overlay tunnel formation is incomplete. It shows remote endpoints such as Controllers, hubs, or branches, along with site type, site name, branch ID, tenant ID, remote WAN link information, and tunnel state-related fields.
show interfaces brief confirms interface state and IP addresses, but it does not show learned remote SD- WAN endpoint objects. CGNAT summary is unrelated to tunnel endpoint learning. System storage is useful for disk checks, but not for SD-WAN overlay endpoint troubleshooting.
