NEW QUESTION # 89
The figure below shows the partial topology of a campus network and the corresponding data plan. The interconnected physical interfaces only allow traffic from the interconnection VLAN, and the corresponding VLANIF interfaces have been created. Across the entire campus network, OSPF is deployed to implement Layer 3 connectivity, and STP is enabled. Given this, which of the following statements are true?
Answer: C,D
Explanation:
The topology contains three Layer 3 interconnection VLANs: VLAN 12 between Core1 and ACC1, VLAN
13 between Core1 and ACC2, and VLAN 23 between ACC1 and ACC2. OSPF is enabled across the campus, while STP still controls Layer 2 forwarding on the VLAN links. If ACC2 GE1/0/3 is an alternate port, STP blocks service forwarding on the ACC1-ACC2 path. As a result, OSPF Hello packets cannot be exchanged across that blocked Layer 2 path and ACC1 and ACC2 cannot establish an OSPF neighbor relationship on VLAN 23, so C is true. Core1 still has routes for all three interconnection networks: VLAN 12 and VLAN 13 are directly connected, and information for VLAN 23 can be learned through OSPF from the access devices, making B true. Statement A is incorrect because ACC1 already has VLANIF 23 as a directly connected network rather than needing to learn that same connected segment through OSPF. Statement D is also false:
STP can still be relevant on Layer 2 VLAN links even in a campus using Layer 3 routing.
NEW QUESTION # 90
The administrator performs the configuration shown in the figure on SW1 and SW2. Initially, PC1 is connected to GE1/0/1 of SW1. After the network is stable, the administrator pings the IP addresses of PC2 and PC3 from PC1. Later, the administrator connects PC1 to GE1/0/2 of SW1. After the network is stable, the administrator pings the IP addresses of PC2 and PC3 from PC1. Which of the following statements is false about this scenario?
Answer: B
Explanation:
The exhibit assigns SW1 GE1/0/1 to VLAN 10 and GE1/0/2 to VLAN 20, while the trunk between SW1 and SW2 carries the required VLANs. When PC1 is connected to GE1/0/1, its untagged frames are classified into VLAN 10. PC2 is also in VLAN 10, so PC1 can communicate with PC2 at Layer 2, whereas PC3 is in VLAN
20 and is separated by the VLAN boundary. SW1 learns PC1 ' s source MAC address together with VLAN 10 and ingress interface GE1/0/1. When PC1 is moved to GE1/0/2, its untagged frames are now placed in VLAN
20. After MAC relearning occurs, PC1 can communicate with PC3, which is also in VLAN 20, but not directly with PC2 in VLAN 10 unless Layer 3 inter-VLAN routing is provided. Consequently, statement A is false because PC1 is not isolated from both hosts after the move; it can communicate with PC3.
NEW QUESTION # 91
A Layer 2 switch works at the data link layer. As such, it can identify MAC addresses in data frames, forward data based on MAC addresses, and record mappings between MAC addresses and interface numbers in its MAC address table.
Answer: A
Explanation:
Layer 2 switches operate at the data link layer, handling frames based on MAC addresses. They maintain a MAC address table to record mappings between MAC addresses and interfaces, allowing efficient frame forwarding within the local network.
NEW QUESTION # 92
The traditional Fat AP networking usually applies to WLANs of small and micro stores. For a large-scale WLAN, the WAC + Fit AP networking is typically used. Which of the following statements are true about the WAC + Fit AP networking architecture? (Select all that apply)
Answer: A,B
Explanation:
In a WAC + Fit AP architecture, the WAC (Wireless Access Controller) centrally manages and controls the Fit APs, so option A is correct. Service configurations such as SSIDs, security policies, radio parameters, and access control are generally delivered from the WAC to the APs. The Fit AP mainly forwards wireless user traffic and executes the configuration issued by the controller.
Option D is also correct because a Fit AP provides 802.11 wireless access for stations (STAs) and serves as a bridge between the wireless side and the wired network. This is one of its basic roles in enterprise WLAN deployment. Option B is incorrect because users or administrators do not normally need to log in to each Fit AP individually to configure wireless services; centralized management by the WAC is the whole advantage of this architecture. Option C is incorrect because CAPWAP communication between the WAC and AP does not require Layer 2 adjacency ; the WAC and AP can communicate over Layer 3 as long as IP connectivity exists. HCIA-Datacom emphasizes centralized configuration, simplified operations, and scalable deployment as key benefits of WAC + Fit AP networking.
NEW QUESTION # 93
The following command output is displayed on R1:
[R1] display aaa configuration
Domain Name Delimiter : @
Domainname parse direction : Left to right
Domainname location : After-delimiter
Administrator user default domain : default_admin
Normal user default domain : default
Domain : total: 256 used: 3
Authentication-scheme : total: 32 used: 2
Accounting-scheme : total: 32 used: 1
Authorization-scheme : total: 32 used: 2
Service-scheme : total: 256 used: 0
Recording-scheme : total: 32 used: 0
Local-user : total: 512 used: 2
Remote-admin-user block retry-interval : 5 Min(s)
Remote-admin-user block retry-time : 3
Remote-admin-user block time : 5 Min(s)
Session timeout invalid enable : No
Which of the following statements is false?
Answer: B
Explanation:
The false statement is B. From the AAA configuration output, the value of Remote-admin-user block time is clearly shown as 5 Min(s), which means the account lockout duration is 5 minutes, not 30 minutes.
