Question 6 of 50

ZTP can retrieve either an EOS configuration file or a script at boot. How does the switch determine of the file being retrieved in a script or a configuration file?

If the first line of the file ends with a shebang (#!), the file is a configuration file.

If the first line of the file starts with a shebang (#!), the file is a script.

If the last line of the file ends with a shebang (#!), the file is a script.

If the last line of the file starts with a shebang (#!), the file is a configuration file.

Correct Answer: B

If the first line of the file starts with a shebang (#!), the file is a script. A shebang (#!) at the beginning of a file is a convention used in many scripting languages to indicate that the file is a script and specify the interpreter to be used. Therefore, the presence of a shebang indicates the file is a script; otherwise, it is treated as a configuration file.

Question 7 of 50

When an Arista switch boots with no startup-config and ZTP enabled, before ZTP receives an IP address, in what state are the front-panel interfaces?

All interfaces are shut down.

All interfaces are disabled.

All interfaces are routed ports (no switchport).

All interfaces are switch ports (switchport).

Correct Answer: C

When an Arista switch boots with no startup-config and ZTP enabled, it configures all Ethernet and Management interfaces with the no switchport command. This means that all interfaces are routed ports (no switchport) before ZTP receives an IP address.

Question 8 of 50

Which of the following Arista switches support LANZ?

7010

7150

7500E

7048T

Correct Answer: B

The Arista 7150 switch supports LANZ (Latency Analyzer). This information can be confirmed through Arista's official datasheets and product documentation for the 7150 series, which highlight its capability to support LANZ. Other models listed do not have the same clear affirmation in their specifications. Therefore, the correct answer is 7150.

Question 9 of 50

Many Arista switches support reversible air flow. When the fans installed on such a switch have red handles, which of the following statements would be correct?

Cold air will be pulled in from the port side of the switch.

Warm air will be pulled in from the starboard side of the switch.

Hot air will be pulled in from the fan side of the switch.

Hot air will be ejected from the fan side of the switch.

Correct Answer: D

Arista switches use color-coded handles to indicate the direction of airflow. A red handle signifies that the fans will eject hot air from the switch. Therefore, the correct statement is that hot air will be ejected from the fan side of the switch.

Question 10 of 50

Given the following output, what can you determine about Ethernet13?

Ethernet13 has a QSFP interface

Ethernet13 has a QSFP+interface

Ethernet13 is an Agile Port

Ethernet13 has a hardware error that is causing it to misreport its connection speed.

Correct Answer: C

Ethernet13 is an Agile Port. Based on the output, Ethernet13 is operating at 40Gb/s and has auto negotiation turned off, which is characteristic of smooth operation that indicates proper configuration rather than any hardware error. This does not align specifically with QSFP or QSFP+ alone but points towards it being an Agile Port, capable of dynamic configuration suitable for various speeds.
