As a part of the Setup Utility, the administrator sets the host name for the BIG IP. What would be the result if the two systems in a redundant pair were set to the same host name.

The correct answer is C. The first time the systems are synchronized the receiving system will be assigned the same selfIP addresses. Setting two BIG-IP systems in a redundant pair to the same hostname can lead to critical configuration conflicts when synchronization occurs.

Question

As a part of the Setup Utility, the administrator sets the host name for the BIG IP. What would be the result if the two systems in a redundant pair were set to the same host name.

Options

  • AHost names do not matter in redundant pair communication.
  • BIn a redundant pair, the two systems will always have the same host name. The parameter is synchronized
  • CThe first time the systems are synchronized the receiving system will be assigned the same selfIP addresses
  • DWhen the administrator attempts to access the configuration utility using the host name, they will always

Why each option

Setting two BIG-IP systems in a redundant pair to the same hostname can lead to critical configuration conflicts when synchronization occurs.

AHost names do not matter in redundant pair communication.

Hostnames are crucial for unique identification and proper management within a BIG-IP redundant pair.

BIn a redundant pair, the two systems will always have the same host name. The parameter is synchronized

Hostnames are typically unique to each device and are not synchronized between BIG-IP systems in a redundant pair.

CThe first time the systems are synchronized the receiving system will be assigned the same selfIP addressesCorrect

If both BIG-IP systems in a redundant pair have the same hostname, during the initial synchronization process, the receiving system may incorrectly adopt configuration parameters, such as Self-IP addresses, from the sending system, leading to duplicate IP addresses and network conflicts. This is because the unique hostname is crucial for distinct identification during configuration and synchronization operations.

DWhen the administrator attempts to access the configuration utility using the host name, they will always

The statement is incomplete and does not describe a full technical result, making it difficult to assess.
