LPIC-3 Exam 304 (Virtualization and High Availability) — Question 9

Which of the following restrictions is true when using KVM with the User Network?

Answer options

• A. Virtual Machines must use a SOCKS proxy to connect to the internet.
• B. Virtual Machines can communicate with the host system and with other virtual machines using User Network.
• C. Virtual Machines can only communicate with other virtual machines but not with the host system.
• D. Virtual Machines cannot use ICMP.
• E. Virtual Machines are restricted to only use IPv6 and not IPv4.

Correct answer: D

Explanation

The correct answer is D because when using User Network in KVM, ICMP packets are not supported, preventing ping and other ICMP-based communications. Options A, B, C, and E are incorrect as they either misrepresent the capabilities of User Network or introduce incorrect restrictions on the communication protocols or host interactions.
