NEW QUESTION # 73
Which of the following packets are exchanged between STAs and an AP to obtain the AP's SSID before association with the AP?
Answer: A,B,D
Explanation:
Probe Request: Sent by the client to detect nearby APs.
Probe Response: Sent by APs in response to the client's request.
Beacon: Periodically broadcast by APs to announce their presence and SSID. The Discovery packet type does not exist in the 802.11 standard.
NEW QUESTION # 74
The figure shows the simplified topology of an enterprise campus network. On this network, the aging time of dynamic MAC address entries on switches is 300 seconds. The administrator connects PC1 to GE1/0/1 of SW1 and successfully pings the IP address of PC2 from PC1. Then, the administrator disconnects the Ethernet cable of PC1 from GE1/0/1 of SW1, immediately connects the cable to GE1/0/2 of SW1, and pings the IP address of PC2 from PC1. Which of the following operations does SW1 perform after receiving a data frame from PC1 when PC1 is connected to GE1/0/2 of SW1?
Answer: A
Explanation:
An Ethernet switch learns MAC address entries dynamically by examining the source MAC address of incoming frames. When SW1 first receives frames from PC1 on GE1/0/1, it creates a MAC address table entry mapping PC1's MAC address to that port. If PC1 later sends frames that arrive on GE1/0/2, SW1 updates the learned entry to reflect the new incoming interface.
Therefore, option B is correct: SW1 saves the mapping between PC1's MAC address and GE1/0/2 and removes or overwrites the old mapping associated with GE1/0/1.
NEW QUESTION # 75
With the continuous update and development of data center services, the architecture of general-purpose computing data center networks is also evolving. A cloud-based data center uses a cloud platform to centrally integrate resources and deliver compute, storage, and network services. Which of the following network architectures is used by such a data center?
Answer: C
Explanation:
Modern cloud data centers require horizontal scalability, high east-west bandwidth, virtualization support, and flexible tenant network extension. A spine-leaf physical topology provides predictable low-hop connectivity between leaf switches by connecting each leaf to the spine layer. VXLAN provides an overlay that can create large numbers of logical Layer 2 segments over the Layer 3 underlay and is well suited to virtualized and multi-tenant cloud environments. The combination of Spine-Leaf and VXLAN is therefore a standard architecture for cloud-based general-purpose data center networks. M-LAG with Eth-Trunk can provide device and link redundancy but does not by itself provide the scalable overlay architecture expected for a cloud fabric. PFC and ECN are lossless-network and congestion-management technologies rather than a complete general-purpose data center architecture. STP with VRRP represents more traditional Layer 2 redundancy and gateway protection and does not offer the same cloud-fabric scalability. Consequently, the architecture described in the question is Spine-Leaf + VXLAN, making option B correct.
NEW QUESTION # 76
On an STP network, an administrator wants SW2 to be elected as the root bridge. Which of the following methods can be used to achieve this goal?
Answer: B
Explanation:
In STP, the root bridge is elected based on the lowest bridge ID (BID). A BID is composed of the bridge priority and the MAC address of the switch. The device with the smallest BID becomes the root bridge.
Therefore, if an administrator wants SW2 to become the root bridge, the most direct and correct method is to configure a lower system priority on SW2, making option C correct.
Option A is incorrect because port priority affects port-role selection in some tie-breaking scenarios, but it does not determine root-bridge election. Option B is the opposite of what is required, because a higher system priority makes the BID larger and reduces the chance of being elected as root. Option D is also incorrect because root path cost is used by non-root bridges to select the best path to the existing root bridge; it does not determine which switch becomes the root bridge in the first place. HCIA-Datacom stresses that bridge priority tuning is the standard administrative method used to control root bridge placement in campus networks for stable and predictable Layer 2 topology design.
NEW QUESTION # 77
The administrator performs the configuration shown in the figure on SW1. After the network is stable, the administrator pings the IP address of PC2 from PC1. The connectivity is normal. Then, the administrator runs the undo vlan 10 command on SW1. After the network is stable, the administrator pings the IP address of PC2 from PC1 again. Which of the following statements are false about this scenario? (Select all that apply)
Answer: A,C,D
Explanation:
Initially, both PC1 and PC2 belong to VLAN 10 through their access interfaces. They therefore communicate within the same Layer 2 broadcast domain.
When VLAN 10 is deleted, the switch removes its associated VLAN membership, and the affected access interfaces revert to the default VLAN 1. Both PCs consequently remain in the same broadcast domain and can communicate.
Option A is true because PC1 can still reach PC2 after both ports return to VLAN 1.
Option B is false because the switch internally associates received frames with VLAN information during forwarding.
Option C is false because the switch can forward traffic in both directions.
Option D is false because the switch no longer assigns the deleted VLAN 10 to incoming frames.
Therefore, B, C, and D are false statements.
