Submit

4. In virtual networking, what is the purpose of a management network or management VLAN?

To provide a dedicated network for hypervisor and infrastructure management

To isolate VM-to-VM traffic from external networks

To encrypt all data transmitted between virtual machines

To assign static IP addresses to all virtual machines

5. What does the term 'uplink' refer to in virtual switching?

A physical network adapter connected to the virtual switch for external connectivity

A virtual connection between two VMs on the same host

The management network of the hypervisor

A backup connection for network redundancy only

6. Which networking mode isolates a VM completely from external networks?

Internal/isolated mode

Bridged mode

NAT mode

Host-only mode with external connectivity

7. What is the primary advantage of using network bonding in virtual environments?

Increased bandwidth and redundancy through multiple physical adapters

Automatic encryption of all network traffic

Elimination of the need for virtual switches

Direct VM access to physical network hardware

8. In virtual networking, what does 'promiscuous mode' on a virtual switch allow?

VMs to receive all network traffic on the switch, not just their own

The host to bypass security policies on the virtual switch

Multiple physical networks to connect to one virtual switch

Automatic failover to backup network connections

9. What is the role of a vNIC (virtual network interface card) in a hypervisor?

To provide a network interface for the hypervisor itself to communicate

To replace the physical NIC of the host completely

To encrypt all traffic between VMs and the host

To manage IP addresses for all virtual machines

10. Which virtual switch feature allows you to monitor and control traffic between VMs?

Traffic shaping and quality of service (QoS) policies

Physical network adapter bonding

Host firewall rules only

DHCP server configuration

11. What is the primary function of a virtual switch in a hypervisor?

To connect virtual machines to physical networks and other VMs

To encrypt all network traffic between VMs

To replace the physical network adapter entirely

To manage CPU resources for network processing

12. In virtual networking, what is the purpose of a virtual port group?

To group virtual network adapters and apply consistent network policies

To increase the number of physical network adapters

To manually configure each VM's MAC address

To bypass security filtering on the virtual switch

13. What is the main difference between a standard switch and a distributed switch?

Distributed switches span multiple hosts; standard switches operate on single hosts

Standard switches are faster than distributed switches

Distributed switches only work with NAT networking

Standard switches support more VMs than distributed switches

14. Which of the following best describes a standard virtual switch?

A switch that operates on individual hosts and connects VMs to networks

A physical switch that connects multiple hypervisors together

A switch that only handles traffic between virtual machines

A switch that replaces the need for physical network adapters

15. What is VLAN tagging used for in virtual switching?

To segment virtual machines into isolated logical networks

To increase the speed of virtual network traffic

To encrypt all data transmitted between VMs

To assign static IP addresses to virtual machines

16. In host-only networking mode, can a virtual machine communicate with external networks?

No, only with the host and other VMs on the same host-only network

Yes, with full access to all external networks

Only if the host is connected to a VPN

Only through bridged adapters configured separately

17. What is Network Address Translation (NAT) in the context of virtual networking?

A technique that allows VMs to access external networks using the host's IP address

A method to physically connect multiple networks together

A security protocol that encrypts all VM traffic

A process that duplicates network packets for redundancy

18. Which virtual switch mode allows a VM to communicate on the same physical network as the host?

Bridged mode

NAT mode

Host-only mode

Isolated mode

19. In virtual networking, what does a virtual network adapter (NIC) do?

Emulates a physical network interface card for the guest OS

Increases the bandwidth of the host physical network

Bypasses the hypervisor to access the network directly

Stores network traffic temporarily for later processing
