JNCIA-DevOps: Juniper Networks Certified Associate – Automation (2021) — Question 10

What is an example of correct XML syntax?

Answer options

• A. <Devices><hostname>vMX1<Devices/>
• B. <Devices><hostname>vMX1</hostname><Devices/>
• C. <Devices><hostname>vMX1</hostname></Devices>
• D. <Devices><hostname>vMX1<Devices/></hostname>

Correct answer: B

Explanation

Option B is correct because it properly closes the <hostname> tag before closing the <Devices> tag. Option A is incorrect due to the unclosed <hostname> tag and improperly nested elements. Option C, while it has correct syntax, contains an extra closing tag that does not match the opening tag structure. Option D also has an unclosed <Devices/> tag within the <hostname> element, which is incorrect.
