Huawei HCIA-Datacom V2.0 H12-811_V2.0 Prüfungsfragen mit Lösungen (Q100-Q105):

100. Frage
On the network shown in the figure, GE1/0/1 of SW1 is an access interface and its PVID is VLAN 2. GE1/0/1 and GE1/0/2 of SW2 are access interfaces and their PVIDs are VLAN 3. The interfaces connecting SW1 and SW2 are trunk interfaces that allow packets from VLAN 2 and VLAN 3 to pass through and retain the default PVID.
The administrator finds that PC2 can dynamically obtain an IP address from the DHCP server, but PC1 cannot. The administrator determines that a possible cause is that PC1 and the DHCP server are in different broadcast domains.

Antwort: B

Begründung:
DHCP automatically assigns IP configuration parameters to network clients. During initial address acquisition, a DHCP client broadcasts a DHCPDISCOVER message to locate available DHCP servers.
Ethernet switches normally forward these broadcasts only within the originating VLAN.
In this scenario, PC1 belongs to VLAN 2, while PC2 and the DHCP server belong to VLAN 3. The trunk connection permits traffic from both VLANs but maintains their Layer 2 isolation.
Therefore, DHCP broadcasts generated by PC1 in VLAN 2 cannot directly reach the DHCP server in VLAN
3.
PC2 can obtain an address because it shares the DHCP server ' s broadcast domain.
Communication between these VLANs would require Layer 3 forwarding, and DHCP relay functionality would normally be required to forward DHCP requests across the VLAN boundary.
Consequently, the administrator ' s explanation is correct.


101. Frage
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.)

Antwort: C

Begründung:
The loopback interface has a /32 address, so OSPF must match the exact host route 10.0.1.1 using a wildcard mask of 0.0.0.0. This ensures only that specific interface is enabled for OSPF.
Other options either cover too broad a range or do not precisely match the loopback /32 address.


102. Frage
Drag and Drop Question
When requesting an IPv4 address for the first time, a DHCPv4 client needs to exchange four messages with the DHCPv4 server. Drag and drop the DHCPv4 packets to the correct positions based on the packet interaction sequence.

Antwort:

Begründung:

Explanation:
1 - DHCP DISCOVER
2 - DHCP OFFER
3 - DHCP REQUEST
4 - DHCP ACK
A DHCP client first broadcasts a Discover message to locate a DHCP server. The server responds with an Offer containing an available IP address. The client then sends a Request to confirm the selected address, and finally the server replies with an ACK to complete the allocation process.


103. Frage
You define the following function in Python: def add(a, b, c):
return a + b + c. You then add the following code. To ensure that the code is correctly executed, sort the following statements in sequence.

Antwort:

Begründung:

Explanation:
1) a = 3; 2) b = a + 3; 3) c = a + b; 4) print(add(a, b, c))

The statements must be executed in dependency order. The function add(a, b, c) can be called only after values have been assigned to the variables that are passed as its three arguments. First, a must be set to 3. The next statement, b = a + 3, depends on a already existing, so it must follow the assignment to a. The statement c = a + b depends on both a and b, so it must be executed after b has been calculated. Finally, print(add(a, b, c)) can run only after a, b, and c all have valid values. With this order, a equals 3, b equals 6, and c equals 9.
The function therefore returns 3 + 6 + 9, and print displays 18. Executing the statements in another order would attempt to reference an undefined variable and raise a NameError. The correct sequence is: a = 3, b = a
+ 3, c = a + b, then print(add(a, b, c)).


104. Frage
With the release of Wi-Fi 7, wireless networks are now faster, more stable, and more latency- tolerant than ever. Which of the following frequency bands are supported by Wi-Fi 7? (Select all that apply)

Antwort: A,C,D

Begründung:
Wi-Fi 7 supports operation in the 2.4 GHz, 5 GHz, and 6 GHz frequency bands, so options A, C, and D are correct. These three bands together provide flexible coverage and capacity options.
The 2.4 GHz band offers better propagation and wider coverage, while the 5 GHz and 6 GHz bands provide more channels, higher capacity, and better support for high-speed, low-latency services.
