CCNP - Cisco Certified Network Professional Practice Questions

Master the Advanced Switching Technologies Domain

Test your knowledge in the Advanced Switching Technologies domain with these 10 practice questions. Each question is designed to help you prepare for the CCNP - Cisco Certified Network Professional certification exam with detailed explanations to reinforce your learning.

Question 1

During a network audit, you discover that some VLANs are not propagating across trunk links. Which command could help diagnose the issue?

A) show vlan brief

B) show interfaces trunk

C) show spanning-tree vlan

D) show mac address-table

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: 'show interfaces trunk' displays information about VLANs allowed on a trunk, helping diagnose propagation issues. 'show vlan brief' lists VLANs on a switch but not their trunk status. Correct, it shows VLANs allowed on trunks. 'show spanning-tree vlan' shows STP info, not trunk propagation. 'show mac address-table' displays MAC addresses, not VLAN propagation.

Question 2

Which QoS mechanism is used to ensure that critical traffic is always prioritized over other types of traffic in a congested network?

A) Traffic Shaping

B) Traffic Policing

C) Priority Queuing

D) Weighted Fair Queuing

Show Answer & Explanation

Correct Answer: C

Explanation: CORRECT: Priority Queuing ensures that critical traffic is always prioritized by placing it in the highest priority queue. Traffic Shaping smooths traffic bursts but doesn't prioritize specific traffic types. Traffic Policing limits the rate of traffic but doesn't prioritize it. Weighted Fair Queuing provides fair bandwidth distribution but doesn't prioritize traffic.

Question 3

What is the primary function of 802.1X in a network environment?

A) To provide VLAN trunking

B) To authenticate devices connected to a LAN

C) To prevent switching loops

D) To aggregate multiple links

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: 802.1X is used to authenticate devices connected to a LAN. 802.1Q, not 802.1X, is used for VLAN trunking. Correct, 802.1X provides authentication for devices. STP is used to prevent switching loops, not 802.1X. LACP is used to aggregate multiple links, not 802.1X.

Question 4

You are troubleshooting an OSPF adjacency issue between two routers. Both routers are in the same subnet, but the adjacency is stuck in the INIT state. What could be the cause?

A) Mismatched OSPF Hello intervals

B) Incorrect subnet mask

C) Mismatched OSPF Router IDs

D) Passive interface configured on one router

Show Answer & Explanation

Correct Answer: A

Explanation: CORRECT: Mismatched OSPF Hello intervals can prevent routers from establishing an adjacency, causing them to remain in the INIT state. This is the correct cause of the issue. An incorrect subnet mask would prevent any communication, not keep the state in INIT. Mismatched Router IDs do not prevent adjacency but may cause issues in route selection. A passive interface would prevent OSPF packets from being sent, not keep the adjacency in INIT.

Question 5

An enterprise network requires high availability and load balancing across multiple WAN links. Which technology should be implemented?

A) HSRP

B) VRRP

C) GLBP

D) Static Routing

Show Answer & Explanation

Correct Answer: C

Explanation: CORRECT: GLBP provides both load balancing and high availability across multiple WAN links. HSRP offers high availability but not load balancing. VRRP offers high availability but not load balancing. GLBP is correct for both load balancing and high availability. Static Routing does not inherently provide load balancing or high availability.

Question 6

Your organization requires that only specific MAC addresses can connect to certain switch ports. Which security feature should you configure?

A) DHCP Snooping

B) Dynamic ARP Inspection

C) Port Security

D) 802.1X Authentication

Show Answer & Explanation

Correct Answer: C

Explanation: Port Security allows you to restrict access to specific MAC addresses on switch ports, preventing unauthorized devices from connecting.

Question 7

In a large enterprise with hundreds of VLANs across multiple switches, which spanning tree variant provides the best scalability and fastest convergence?

A) Per-VLAN Spanning Tree Plus (PVST+)

B) Rapid Spanning Tree Protocol (RSTP)

C) Multiple Spanning Tree Protocol (MSTP)

D) Common Spanning Tree (CST)

Show Answer & Explanation

Correct Answer: C

Explanation: MSTP maps multiple VLANs to spanning tree instances, providing better scalability and faster convergence than PVST+ in large environments.

Question 8

Your current topology requires segmentation of multicast traffic to ensure efficient use of bandwidth. Which feature can help achieve this?

A) Multicast VLAN Registration (MVR)

B) IGMP Snooping

C) Static Routing

D) MAC Filtering

Show Answer & Explanation

Correct Answer: A

Explanation: MVR allows multicast traffic to cross VLANs, optimizing bandwidth usage for multicast streams.

Question 9

You need to combine four physical links between two switches to increase bandwidth and provide redundancy. What is the maximum number of active links you can bundle in a single EtherChannel?

A) 4

B) 6

C) 8

D) 16

Show Answer & Explanation

Correct Answer: C

Explanation: EtherChannel supports bundling up to 8 physical links into a single logical channel for increased bandwidth and redundancy.

Question 10

In a network running MST, a new VLAN is added. How does this affect the existing MST instances if not explicitly mapped?

A) It becomes part of the default instance 0.

B) It is automatically mapped to a new instance.

C) It remains inactive until manually assigned.

D) It causes all existing instances to recalculate topology.

Show Answer & Explanation

Correct Answer: A

Explanation: In MST, any VLANs not explicitly mapped to an instance are automatically part of the default instance 0, which handles all unassigned VLANs. Options B and C are incorrect as VLANs are automatically handled by instance 0 unless mapped. Option D is incorrect as topology recalculations only occur if mappings change, not just by adding a VLAN.
