Network Fundamentals and Monitoring Foundations (Questions 1–10)
Q1. A network engineer is reviewing traffic patterns in a corporate LAN. Users report
intermittent delays when accessing internal applications. Packet captures show
excessive broadcasts originating from multiple departments connected to the same
Layer 2 domain. Which action would most effectively reduce broadcast traffic while
improving network scalability?
A. Increase the Ethernet frame size
B. Configure additional VLANs and implement Layer 3 routing between them
C. Disable Spanning Tree Protocol on access switches
D. Replace all copper links with fiber connections
Correct Answer: 🔴 B. Configure additional VLANs and implement Layer 3 routing
between them
Explanation: 🔹 VLAN segmentation reduces the size of broadcast domains by
separating users into logical networks. Inter-VLAN routing allows communication
between segments while preventing unnecessary broadcast propagation. Increasing
frame size does not address broadcasts, disabling STP introduces switching risks, and
replacing cables does not reduce broadcast volume.
Q2. A network administrator wants continuous visibility into bandwidth utilization,
interface errors, and packet loss trends across enterprise routers. Which monitoring
approach provides the most appropriate solution?
A. Periodically checking router LEDs
B. Using SNMP-based network monitoring software
C. Reviewing user complaints only
D. Performing manual cable inspections
,Correct Answer: 🔴 B. Using SNMP-based network monitoring software
Explanation: 🔹 SNMP enables centralized monitoring systems to collect operational
statistics from network devices, including interface counters, utilization, and errors.
LEDs and manual checks provide limited information, while user complaints identify
symptoms rather than network conditions.
Q3. A company deploys a new network monitoring platform that collects real-time
interface statistics from switches. The administrator notices that one interface
frequently reaches maximum utilization during business hours. Which metric is most
important for confirming a congestion issue?
A. CPU temperature
B. Interface bandwidth utilization percentage
C. Device hostname length
D. MAC address table size
Correct Answer: 🔴 B. Interface bandwidth utilization percentage
Explanation: 🔹 Interface utilization directly indicates whether a link is approaching
capacity. CPU temperature and hostname information are unrelated to traffic
congestion, while MAC table size does not measure link saturation.
Q4. A technician needs to identify whether a connectivity problem occurs at Layer 2
or Layer 3. The technician verifies that a device has learned the correct MAC address
but cannot reach a remote subnet. Which tool would provide the best next
diagnostic step?
A. ping
B. traceroute
C. show vlan
D. show mac address-table
Correct Answer: 🔴 B. traceroute
, Explanation: 🔹 Traceroute identifies the Layer 3 path between devices and helps locate
where routing failures occur. MAC verification already confirms Layer 2 learning. Ping
confirms reachability but provides less path visibility.
Q5. A monitoring engineer observes that several switches are reporting duplicate
MAC addresses appearing on different ports. Which condition is the most likely
cause?
A. Incorrect DNS configuration
B. A Layer 2 loop or switching instability
C. Incorrect subnet mask on a host
D. Excessive DHCP lease duration
Correct Answer: 🔴 B. A Layer 2 loop or switching instability
Explanation: 🔹 Duplicate MAC movement often indicates switching loops, incorrect
cabling, or instability in the Layer 2 topology. DNS, subnet masks, and DHCP timers do
not cause MAC addresses to move between switch ports.
Q6. A network operations team wants to receive immediate alerts when a router
interface fails. Which monitoring mechanism is most appropriate?
A. SNMP traps
B. Static routing
C. ARP inspection
D. VLAN pruning
Correct Answer: 🔴 A. SNMP traps
Explanation: 🔹 SNMP traps allow devices to proactively send event notifications to
monitoring systems. Static routing, ARP inspection, and VLAN pruning perform
network functions but do not provide direct failure alerts.
