Question 1

What protocol is used to provide a common language between virtualized service applications and a network's physical devices?
A)VRRP
B)OpenFlow
C)CommonStack
D)OpenArch

Accepted Answer

The protocol that is used to provide a common language between virtualized service applications and a network's physical devices is OpenFlow. OpenFlow is a widely accepted protocol that enables network administrators to control the flow of traffic in a software-defined network (SDN). It allows communication between the control plane and the data plane of a network, making it easier to manage and control network resources. VRRP is a protocol used to provide redundancy for IP networks. CommonStack and OpenArch are not protocols related to networking.

Question 2

Which of the following describes a router protocol that is used to assign a virtual IP address to a group of routers so that the routers function as a group? 
A)VRRP
B)GBRP
C)HSRP
D)CARP

Accepted Answer

VRRP (Virtual Router Redundancy Protocol) and HSRP (Hot Standby Router Protocol) both allow a group of routers to work together and share one virtual IP address as a virtual gateway. This improves network availability and provides redundancy in case one of the routers fails. GBRP (Group Border Gateway Protocol) and CARP (Common Address Redundancy Protocol) are also routing protocols, but they are not used for virtual IP address assignment in a router group.

Question 11

What two standards below have been developed to replace the Spanning Tree Protocol?
A)TRILL
B)SPB
C)VSRP
D)HSRP

Accepted Answer

TRILL (Transparent Interconnection of Lots of Links) and SPB (Shortest Path Bridging) are two standards that have been developed to replace the Spanning Tree Protocol. TRILL is an IETF standard while SPB is an IEEE standard. Both of these standards aim to provide faster convergence, improved scalability, and greater flexibility compared to the Spanning Tree Protocol. Therefore, A and B are the best choices. VSRP (Virtual Router Redundancy Protocol) and HSRP (Hot Standby Router Protocol) are not related to the replacement of the Spanning Tree Protocol.

Question 12

A CIDR block of /26 is equivalent to what subnet mask below?
A)255.255.192.0
B)255.255.254.0
C)255.255.255.192
D)255.255.0.0

Accepted Answer

A /26 CIDR block represents 64 IP addresses. The subnet mask that can provide 64 IP addresses is 255.255.255.192. Therefore, the correct choice is C. The other options do not provide the appropriate number of IP addresses.

Answer: J
 Virtual Router Redundancy Protocol (VRRP) is a protocol that provides redundancy for IP networks, ensuring that the IP address of a virtual router is always available even if the primary router fails.

Note: The other options (A, B, C, D, and E) are unrelated to the concept of virtualization and server management.

Question 14

The management option that can provide on-site infrastructure access when the network is downor completeremote access in cases of connectivity failures on the network,such as via a cellularsignal,is known as?
A)in-band management
B)out-of-band management
C)open management
D)side channel management

Accepted Answer

Out-of-band management allows for access to network infrastructure when the network is down or when there are connectivity failures, such as via a cellular signal. In-band management, on the other hand, requires connectivity to the network and would not be useful in these situations. Open management and side channel management are not commonly used terms in the context of network management.

Question 15

Which virtual network type allows VMs to communicate with each other on the same host,but disallows communication with other nodes on the network?
A)host-only mode
B)bridged mode
C)NAT mode
D)restricted mode

Accepted Answer

Host-only mode creates a virtual network that allows communication between virtual machines on the same host, but does not allow communication with other nodes on the network. This is ideal for testing or development scenarios where isolated communication is required. Bridged mode and NAT mode allow communication with other nodes on the network, while restricted mode is not a valid virtual network type.

Question 16

Matching
