NEW QUESTION # 113
A small enterprise's switches do not support LACP. Therefore, the administrator manually binds two links between two switches into an Eth-Trunk. Which of the following statements are false about this scenario? (Choose all that apply.)
Answer: A,D
Explanation:
Manually configured Eth-Trunk (static aggregation) does not support dynamic link management features such as automatic link addition or load-based negotiation. If a link fails, it is simply removed from forwarding but not automatically replaced by another link, and the system does not dynamically add new active links.
Also, static Eth-Trunk operates in load-sharing mode, not active/standby mode, so both links forward traffic simultaneously under normal conditions.
NEW QUESTION # 114
Enterprise data center (DC) services are no longer carried by physical machines or provided only for internal users. Instead, cloud platforms integrate resources in a unified manner and provide services for external users. Continuous service innovation requires the DC construction mode to evolve from single-DC to multi-site multi-DC.
Answer: B
Explanation:
Modern enterprise data centers are no longer limited to physical machines or internal-only services. With cloud computing, resources are pooled and abstracted to provide services to both internal and external users. To support scalability, high availability, and continuous service innovation, data center architectures have evolved from single-site deployments to multi-site, multi-data center designs.
NEW QUESTION # 115
Assume that you cannot configure an IP address for GE1/0/1 on a Huawei switch. Which of the following commands can you run in the interface view to resolve this problem?
Answer: D
Explanation:
On Huawei switches, a physical Ethernet interface usually works as a Layer 2 switch port by default. A Layer 2 interface cannot be assigned an IP address directly. If an administrator wants to configure an IP address on such an interface, the interface must first be converted into a Layer 3 interface . The command used for this is undo portswitch , so option B is correct.
After this command is executed, the interface no longer behaves as a Layer 2 switching port and can then support Layer 3 features such as direct IP address configuration. Options A , C , and D are all Layer 2 port- type commands used to configure the interface as a trunk, access, or hybrid port. These commands do not solve the problem because they keep the interface operating at Layer 2. HCIA-Datacom emphasizes the difference between Layer 2 switching interfaces and Layer 3 routed interfaces on switches. Understanding when to use undo portswitch is important in campus network deployment, especially when configuring routed uplinks, management interfaces, or inter-device Layer 3 links on switches.
NEW QUESTION # 116
Which of the following SNMP messages is sent unsolicited to the NMS by a managed device to report some urgent and significant events (such as a restart of the managed device)?
Answer: B
Explanation:
In SNMP, a Trap message is sent asynchronously and unsolicited from a managed device to the NMS to report important or urgent events such as device restart, link failures, or threshold alarms.
It does not require a response from the NMS, unlike Inform messages.
NEW QUESTION # 117
Which of the following phases are required for establishing a connection between an SSH server and an SSH client? (Select all that apply)
Answer: A,B,C,D
Explanation:
The establishment of an SSH connection includes multiple mandatory phases that ensure both secure communication and authenticated access. First, the SSH client and server perform version negotiation to determine a mutually supported SSH protocol version. Then they carry out algorithm negotiation, during which they agree on the encryption algorithm, key exchange algorithm, integrity algorithm, and other security parameters to be used for the session.
After that, the peers perform key exchange, which is used to derive shared session keys securely over an insecure network. This stage is essential because it enables subsequent communication to be encrypted and protected against interception. Finally, once the secure channel has been established, user authentication is performed so that the server can verify the identity of the client user. This can be done using a password, public key, or other supported authentication method.
Therefore, all four options are required phases in the SSH connection establishment process.
HCIA-Datacom emphasizes these steps because SSH is a core secure management protocol used to replace insecure protocols such as Telnet and FTP in modern network operation and maintenance.
