PC1 and PC2 are connected to the same switch, but they cannot learn each other’s ARP information.
This may be caused by incorrect VLAN configuration on the switch.
- A . TRUE
- B . FALSE
In a wireless communication system, information is first converted into digital signals for easy circuit calculation and processing by the transmitter through source coding, and then converted into radio waves through channel coding and modulation.
Which of the following parameters of a carrier are modified during the modulation process based on signal changes? (Select all that apply)
- A . Frequency
- B . Phase
- C . Channel
- D . Amplitude
During WLAN deployment, a Fit AP fails to go online on the WAC.
Which of the following commands can you run on the WAC to locate the fault? (Choose all that apply.)
- A . display ap all
- B . display ap online-fail-record all
- C . display vap all
- D . display ssid-profile all
Which of the following commands can be used to enable OSPF on the loopback interface (10.0.1.1/32) of R1? (Choose all that apply.)
- A . network 0.0.0.0 255.255.255.255
- B . network 10.0.0.0 0.0.255.255
- C . network 10.0.1.1 0.0.0.0
- D . network 10.0.1.0 0.0.0.255
Unlike distance-vector routing protocols, link-state routing protocols advertise link states instead of route information. Typical link-state routing protocols include RIP, OSPF, and IS-IS.
- A . TRUE
- B . FALSE
On the campus network shown in the figure below, the core switch Core1 functions as a Layer 3 gateway and as a DHCP server to dynamically assign IP addresses to AP1, PC1, PC2, and PC3. The network below Core1 is a Layer 2 network. WAC1 and R1 are connected to Core1 at Layer 3. AP1 goes online through VLAN 100. The wireless service VLAN is VLAN 101, and the wired service VLANs for PC2 and PC3 are VLAN 102 and VLAN 103, respectively.
Additionally, the direct forwarding mode is used for wireless traffic forwarding. If no additional VLANs are allowed on device interfaces, which of the following VLANs must be allowed on GE1/0/1 of ACC1? (Select all that apply)
- A . VLAN 100
- B . VLAN 101
- C . VLAN 102
- D . VLAN 200
With the development of data centers, a large number of services are deployed on virtual machines (VMs). The original VLAN isolation solution cannot achieve isolation between so many VMs. VXLAN uses VXLAN Network Identifiers (VNIs) to provide a larger range than VLAN IDs, so that a larger number of VMs can be isolated.
- A . TRUE
- B . FALSE
In the WAC + Fit AP networking, an AP fails to go online.
The output of the display ap all command run on the WAC is shown below.
According to the command output, which of the following is the possible cause of the AP’s failure to go online?
- A . The AP is in the blacklist.
- B . The AP fails the authentication.
- C . The AP’s software version does not match the WAC’s software version.
- D . The AP fails to initialize the configuration.
DRAG DROP
On a general-purpose computing data center network, network administrators need to use various network technologies or architectures to ensure high network stability and efficiency. Match the following network technologies or architectures with the requirements they meet.
A Huawei network device functioning as an AAA server is referred to as a local AAA server. Compared with a remote AAA server, a local AAA server reduces operation costs.
However, the amount of information that can be stored on a local AAA server is limited by the hardware performance of the device.
- A . TRUE
- B . FALSE
