Question 1,648 of 2,015

Network Function Virtualization →mediumMatchingObjective-mapped

Quick Answer

The answer is KVM, which is a Linux-based Type 1 hypervisor that is integrated directly into the kernel. This is correct because Type 1 hypervisors, also known as bare-metal hypervisors, run directly on the host hardware without an underlying operating system, making them efficient for data center environments; KVM leverages the Linux kernel to perform this function, effectively turning Linux into a hypervisor. On the ENCOR 350-401 exam, hypervisor types matching questions test your ability to distinguish between Type 1 and Type 2 hypervisors, often presenting KVM alongside VMware ESXi or Microsoft Hyper-V as Type 1 examples, while Type 2 options like VirtualBox or VMware Workstation run on a host OS. A common trap is confusing KVM as a Type 2 hypervisor because it runs on Linux, but remember: since it is part of the kernel, it has direct hardware access. For a quick memory tip, think “KVM = Kernel Virtual Machine, Type 1 because the kernel is the hardware interface.”

Correct answer & explanation

✓

Type 1 hypervisor: Runs directly on physical hardware without a host OS

Type 1 hypervisors run directly on hardware and are common in data centers; Type 2 run on a host OS and are used for desktop virtualization.

Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Common exam traps

Common exam trap: ACLs stop at the first match

ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.

Detailed technical explanation

How to think about this question

ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.

KKey Concepts to Remember

Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.

TExam Day Tips

Check inbound versus outbound direction.
Read the ACL from top to bottom.
Look for a broader permit or deny above the intended line.

Key takeaway

ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Real-world example

How this comes up in practice

A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.

What to study next

Got this wrong? Here's your next step.

Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related 350-401 ACL questions on filtering logic and placement.
