On a campus network, the gateway is usually configured on the aggregation layer. What advantages
does this design have compared with configuring the gateway on the access layer? (Multiple Choice)

• A. Reduce the broadcast domain on the network and the probability of broadcast storms.
• B. Achieve separate convergence of Layer 2 and Layer 3 to increase the convergence speed and network stability.
• C. Properly design the Layer 2 network scale, reduce network segment allocation, and improve network management efficiency.
• D. Allow configuring access devices as Layer 2 devices, reducing network construction costs.
• E. Leverage the STP and VRRP mechanisms to improve network reliability.

Which of the following statements regarding the basic device information check is true?

• A. You can run the display patch-information command to check patch information.
• B. The device time should be consistent with the actual time (time difference < 24 hours) so that a fault can be accurately located based on the occurrence time.
• C. The debugging functions can be enabled when the device is running properly.
• D. You can run the display current-configuration command to check the PCB version and the software version of a card.

Which of the following WAN links are used on a packet switched network? (Multiple Choice)

• A. ATM
• B. ISDN
• C. MSTP
• D. PSTN
• E. X.25

During the migration test, which of the following indicates that the test is completed?

Current enterprise networks usually use OSPF as the routing protocol. What precautions are there
when OSPF is used? (Multiple Choice)

• A. Determine that the backbone area will not split.
• B. Check whether secondary optimal routes exist on the network according to OSPF route selection rules.
• C. Check whether all non-backbone areas are correctly and reliably connected to the backbone area.
• D. Check the OSPF network topology and ensure that no loop exists when OSPF routes are being calculated.
• E. Verify that OSPF costs can correctly demonstrate the actual bandwidth of links at more than 100 Mbit/s.
