FDNY Z51 EXAM 3 MOCK TEST 2026 FULL
QUESTION WITH ANSWERS AND DETAILED
EXPLANATIONS STUDY GUIDE
◉ Service Connectivity Monitor.
Answer: Monitors outbound connectivity from nodes on your
network to any external service with an open TCP port, such as web
sites, applications, or databases.
◉ ExpressRoute Monitor.
Answer: Allows you to monitor end-to-end network connectivity
and performance between on-premises and Azure endpoints over
ExpressRoute connections. It can auto-detect ExpressRoute circuits
and your network topology, and track bandwidth utilization, packet
loss and network latency.
◉ Azure Network Watcher.
Answer: Provides a central hub for a wide range of network
monitoring and diagnostic tools.
◉ IP Flow Verify.
Answer: The IP Flow Verify tool provides a quick and easy way to
test whether a given network flow will be allowed into or out of an
,Azure virtual machine. It will report whether the requested traffic is
allowed or blocked, and in the latter case, which NSG rule is blocking
the flow. It is a useful tool for verifying that NSGs are correctly
configured.
◉ Next Hop.
Answer: The Next Hop tool provides a useful way to understand how
a VM's outbound traffic is being directed. For a given outbound flow,
it shows the next hop IP address and type and the route table ID of
any user-defined route in effect
◉ Packet Captures.
Answer: The Packet Capture tool allows you to capture network
packets entering or leaving your virtual machines. It is a powerful
tool for deep network diagnostics. Use WireShark or Microsoft
Message Analyzer to read the file
◉ Network Topology.
Answer: Provides a diagrammatic view of the resources in your
virtual network. It is not a diagnostic or alerting tool. It is a quick
and easy way to review your network resources and manually check
for misconfiguration.
◉ Network Watcher tools.
Answer: 1. IP Flow Verify
, 2. Next Hop
3. VPN Troubleshoot
4. Packet Capture
5. Connection Troubleshoot
6. Effective Security Rules
◉ VPN Troubleshoot Tool.
Answer: Provides automated diagnostics of Azure VPN gateways and
connections. The results provide a detailed report on gateway health
and connection health, providing accurate pointers regarding
common issues that might occur when enabling informed
remediations.
◉ Connection Troubleshoot Tool.
Answer: A Network Watcher feature designed to allow you to test
the connectivity between an Azure VM or an App Gateway and
another endpoint—either another Azure VM, or an arbitrary
Internet or Intranet endpoint.
◉ Hybrid networks.
Answer: Commonly used for Intranet applications, which may be
hosted in Azure but only accessed from the on-premises network.
They are also used by Azure applications that require access to an
on-premises resource, such as a database.
