NEW QUESTION # 51
On the switched network shown in the figure, STP is enabled on all devices. SW1 is the root bridge. The port costs are shown in the figure. Other parameters retain the default values. After the network is stable, which of the following ports are alternate ports? (Choose all that apply.)
Answer: B,C
Explanation:
To find the alternate ports, we first identify the quickest path to the root bridge, SW1, for every other switch. SW2 reaches the root directly through its top port with a cost of 30. SW3 has the fastest direct path with a cost of 10. SW4 calculates that going through SW3 is cheaper than going directly to the root, giving it a total root cost of 40. SW5 finds its best path by going through SW4, resulting in a total root cost of 50. All of these preferred entry points become Root Ports.
Next, we look at the remaining open links to see which ports must be blocked to prevent loops.
On any connection between two switches, the switch that is further away from the root bridge loses the battle and has to block its port, turning it into an Alternate Port.
When comparing the cross-link between SW1 and SW4, SW1 is the root bridge itself, so SW4 loses this matchup and blocks its GE1/0/3 port. Looking at the link between SW3 and SW5, SW3 is much closer to the root bridge with a cost of 10 compared to SW5's cost of 50, which forces SW5 to block its GE1/0/1 port. On the remaining links, SW2 forces SW4 to block its GE1/0/2 port, and SW3 forces SW2 to block its GE1/0/3 port.
Matching these blocked paths to the given choices leaves us with GE1/0/3 of SW4 and GE1/0/1 of SW5 as the alternate ports.
NEW QUESTION # 52
A router ID uniquely identifies a device in an AS, and must be present before the device can run OSPF. For a device running OSPFv2, if no router ID is manually configured, the system automatically selects one.
Answer: B
Explanation:
In OSPFv2, a router ID is required for OSPF to operate and uniquely identifies each router within an AS. If no manual router ID is configured, the system automatically selects the highest IP address of a loopback interface; if no loopback exists, it selects the highest IP address of a physical interface. Therefore, the statement is correct.
NEW QUESTION # 53
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: B
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 # 54
On the OSPF network shown in the figure, all IP addresses can communicate with each other.
Then the following configurations are added on R1:
[R1] acl 3000
[R1-acl4-advance-3000] rule deny ip source 10.0.1.1 0.0.0.0
[R1-acl4-advance-3000] rule deny ip source 10.1.1.1 0.0.0.0
[R1-acl4-advance-3000] rule permit ip source 10.3.1.1 0.0.0.0
[R1-acl4-advance-3000] rule permit ip
[R1-acl4-advance-3000] quit
[R1] traffic classifier test
[R1-classifier-test] if-match acl 3000
[R1-classifier-test] quit
[R1] traffic behavior test
[R1-behavior-test] permit
[R1-behavior-test] quit
[R1] traffic policy test
[R1-trafficpolicy-test] classifier test behavior test
[R1-trafficpolicy-test] quit
[R1] interface GE 0/0/1
[R1-GE0/0/1] traffic-policy test outbound
[R1-GE0/0/1] quit
Which IP addresses of S1 can successfully ping 10.0.23.3? (Select all that apply)
Answer: A,B,C,D
Explanation:
All four addresses can successfully ping 10.0.23.3, so the correct answer is A, B, C, D.
The key point is that the traffic policy is applied outbound on GE0/0/1 of R1, which is the interface facing S1. When S1 pings 10.0.23.3, the echo request travels from S1 to R1 and then to S2. The return echo reply from 10.0.23.3 comes back to R1 and is then sent outbound on GE0/0/1 toward S1. Therefore, the traffic policy examines the reply packets, not the original ping request packets.
In those reply packets, the source IP address is 10.0.23.3, and the destination is one of S1's loopback addresses. The ACL rules denying 10.0.1.1 and 10.1.1.1 as source addresses do not match these reply packets, because those addresses appear as destination addresses, not source addresses. In addition, the ACL contains rule permit ip, which permits all remaining IP traffic. As a result, replies to all four S1 addresses are forwarded successfully, so every listed address can ping 10.0.23.3.
NEW QUESTION # 55
Which of the following commands can be used to enable OSPF on the loopback interface (10.0.1.1/32) of R1?
(Select all that apply)
Answer: A,B,C,D
Explanation:
In Huawei OSPF configuration, the network command identifies interfaces whose IP addresses match the specified network address and wildcard mask.
A wildcard mask uses zero bits to indicate positions that must match exactly and one bits to indicate positions that can vary.
Option A matches only the specific address 10.0.1.1.
Option B matches all addresses within 10.0.1.0/24, including 10.0.1.1.
Option C matches the larger 10.0.0.0/16 range, which also includes the loopback address.
Option D uses a wildcard mask of 255.255.255.255, meaning that all IPv4 address bits are ignored during matching. Consequently, every eligible IPv4 interface address matches.
All four commands therefore match the loopback interface address and can enable OSPF on that interface when configured in the appropriate OSPF area.
The correct answers are A, B, C, and D.
