,Q1. In a network with rapid PVST+ and an uplink to a root bridge, which
configuration ensures that a switch immediately transitions an alternate port to
forwarding upon root port failure?
A. Set the port to PortFast and enable BPDU guard
B. Enable UplinkFast globally
C. Configure the port as an uplinkfast port
D. Use the 'spanning-tree uplinkfast' command on the switch
Correct Answer: D. Use the 'spanning-tree uplinkfast' command on the switch
Rationale: UplinkFast allows an alternate port to transition to forwarding immediately
when the root port fails, without waiting for STP convergence. PortFast and BPDU guard
are for access ports, not uplink recovery.
Why Wrong:
A - PortFast and BPDU guard are for access ports, not for uplink failover.
B - UplinkFast must be enabled globally, not just on the port.
C - There is no such configuration as an 'uplinkfast port'.

Q2. Which technology allows a network administrator to separate a large broadcast
domain into smaller logical segments without changing the physical topology?
A. VLAN trunking
B. Subnetting
C. STP
D. VTP pruning
Correct Answer: A. VLAN trunking
Rationale: VLANs create separate broadcast domains logically, even on the same switch.
Subnetting is a logical IP addressing scheme but does not inherently segment broadcast
domains without VLANs. STP prevents loops, and VTP pruning is for trunk optimization.
Why Wrong:
B - Subnetting alone does not create separate broadcast domains at Layer 2.
C - STP prevents loops but does not segment broadcast domains.
D - VTP pruning reduces unnecessary broadcast traffic but does not create segments.

Q3. A network engineer is designing a wireless network for a dense office
environment. Which configuration minimizes co-channel interference while
maximizing throughput?
A. Use 2.4 GHz with 20 MHz channels
B. Use 5 GHz with 80 MHz channels
Page 3
, C. Enable band steering to push clients to 5 GHz and use 40 MHz channels
D. Use only 2.4 GHz with 40 MHz channels
Correct Answer: C. Enable band steering to push clients to 5 GHz and use 40 MHz
channels
Rationale: Band steering moves dual-band clients to 5 GHz, which has more
non-overlapping channels and less congestion, while 40 MHz channels offer higher
throughput. 80 MHz in dense environments increases interference, and 2.4 GHz is more
crowded.
Why Wrong:
A - 2.4 GHz is more congested and 20 MHz offers lower throughput.
B - 80 MHz channels are prone to interference in dense environments.
D - 2.4 GHz with 40 MHz causes excessive overlap and interference.
Reference: Cisco CCNA 200-301 Official Cert Guide, Odom, Ch. 14
Q4. Which statement accurately describes the behavior of an IPv6 neighbor
solicitation message when a host performs duplicate address detection?
A. It is sent to the solicited-node multicast address of the tentative address
B. It is sent to the all-nodes multicast address
C. It is sent to the unicast address of the target
D. It is sent to the all-routers multicast address
Correct Answer: A. It is sent to the solicited-node multicast address of the tentative
address
Rationale: DAD uses neighbor solicitation messages sent to the solicited-node multicast
address, which is derived from the tentative address. This ensures that only nodes with the
same address respond.
Why Wrong:
B - All-nodes multicast is used for other purposes, not DAD.
C - Unicast is not used because the address is tentative and not assigned.
D - All-routers multicast is used for router discovery, not DAD.
Reference: Cisco CCNA 200-301 Official Cert Guide, Odom, Ch. 12
Q5. Given the following JSON payload from a REST API, which Python code
correctly extracts the 'status' of the second interface and prints it?
A. print(data['interfaces'][1]['status'])
B. print(data['interfaces'][1].get('status'))
C. print(data['interfaces'][2]['status'])
D. print(data['interfaces'][1]['status']['up'])
Correct Answer: B. print(data['interfaces'][1].get('status'))
