The network administrator has decided to configure link aggregation in the enterprise network. Which of the following represent advantages of link aggregation?
- A. Improved security.
- B. Improved bandwidth.
- C. Load balancing.
- D. Enhanced reliability.
Answer: B,C,D
Explanation:
* A (Correct) - Load Balancing: Link aggregation distributes traffic across multiple physical links, reducing congestion and improving performance.
* B (Correct) - Improved Bandwidth: Multiple links act as a single logical link, increasing the total available bandwidth.
* C (Correct) - Enhanced Reliability: If one link in an aggregated group fails, traffic is rerouted through the remaining links, improving network resilience.
* D (Incorrect) - Improved Security: Link aggregation does not inherently improve security; it primarily enhances performance and fault tolerance.
Thus, the correct answers are A, B, and C.

- A. The largest IP address of the physical interface of the router will become the Router ID
- B. The IP address of the router's management interface will become the Router ID
- C. The priority of the router will become the Router ID
- D. The smallest IP address of the router's physical interface will become the Router ID
Answer: A
NEW QUESTION # 187
As shown in the figure below, which of the following statements is correct? () (Single-choice question)
- A. B.Only if the masks of host A and host B are set to be the same, host A and host B can communicate
- B. The IP address mask b of host A and host B are different. Therefore, host A and host B cannot communicate

NEW QUESTION # 191
Which of the following statements about link aggregation in manual load balancing mode is correct?
- A. In manual load sharing mode, all active interfaces participate in data forwarding and share load traffic
- B. The number of active ports can be configured in manual load sharing mode
- C. There can only be 4 active ports in manual load sharing mode

NEW QUESTION # 192
In the following figure, all links are Ethernet links, and all interfaces on the routers are running OSPF. Given this, how many DRs will be elected on this network?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
In OSPF networks, a DR (Designated Router) is elected for each broadcast domain, such as each Ethernet segment. Given the topology where there are multiple Ethernet segments, a DR will be elected in each segment, resulting in three DRs based on the configuration and network design.

In the following figure, all links are Ethernet links, and all interfaces on the routers are running OSPF. Given this, how many DRs will be elected on this network?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
Comprehensive Explanation: On a network consisting of multiple broadcast domains (like Ethernet links), OSPF will elect one DR (Designated Router) and one BDR (Backup Designated Router) per broadcast segment. In this topology, two Ethernet segments are formed, so two DRs will be elected
