Question 3

Matching
Match each correct item with the statement below.
-The interface on a switch used for an end node.Devices connected to access ports are unaware of VLANinformation.

Accepted Answer

An access port is the interface on a switch used for an end node.

Answer: E 
 Devices connected to access ports are unaware of VLAN information, but the native VLAN can be set to carry untagged traffic for devices connecting to access ports.

Answer: G 
 A trunk port carries traffic for multiple VLANs and is used to connect switches together.

Answer: H 
 A virtual server is a software-based emulation of a physical server and can run multiple instances of operating systems on a single physical server.

Answer: I 
 VLAN hopping attack is an attack that allows an attacker to send traffic to destinations in a VLAN other than their own.

Note: The other choices are also networking concepts, but they do not match the statements provided in the question.

Question 4

Matching
Match each correct item with the statement below.
-Cisco's proprietarystandard,similar to VRRP,that assigns a virtual IP address toa group of routers.At first,messages routed to the virtual IPaddress are handled by the active router.If the active routerfails,standby routers stand in line to take over responsibilityfor the virtual IP address.

Accepted Answer

HSRP (Hot Standby Routing Protocol) is a proprietary standard similar to VRRP, that assigns a virtual IP address to a group of routers. At first, messages routed to the virtual IP address are handled by the active router. If the active router fails, standby routers stand in line to take over responsibility for the virtual IP address.

No other choice matches the given statement.

Question 5

Matching
Match each correct item with the statement below.
-In CIDR notation,the forward slash plus thenumber of bits used for the network ID.For example,theCIDR block for 199.34.89.0/22 is /22.

Accepted Answer

The statement is describing CIDR block notation.

Answer: J
 VRRP (Virtual Router Redundancy Protocol) is the only protocol mentioned in the options that fits the description of "Virtual Router Redundancy Protocol".

Answer: E
 "Native VLAN" is the only option that matches the term given.

Answer: G
 "Trunk port" is the only option that describes a port used to carry traffic for multiple VLANs.

Answer: F
 "Software defined networking (SDN)" is the only option that fits the description of a networking approach that separates the control plane from the data plane to enable more centralized, programmable management.

Answer: I
 "VLAN hopping attack" is the only option that describes a security exploit where an attacker sends packets between VLANs on a trunk port in order to gain unauthorized access.

Note: The options A, B, D, and H are not mentioned in the statement so they cannot be matched.

Question 6

Matching
Match each correct item with the statement below.
-The interface on a switch capable of managingtraffic from multiple VLANs.A trunk is a link configuredbetween two switches' trunk ports.

Accepted Answer

A trunk port is a link configured between two switches' trunk ports, capable of managing traffic from multiple VLANs.

Answer: A
 An access port is a port where devices connect to a switch, often assigned to a single VLAN.

Answer: E
 The native VLAN is the default VLAN for an access port, and is used when untagged traffic is sent to a trunk port.

Answer: I
 VLAN hopping is a network attack where a hacker exploits a vulnerability in a switch's configuration to gain access to data on another VLAN.

Answer: F
 Software defined networking (SDN) is a network architecture that separates the control plane from the data plane, allowing for more flexible, centralized management.

Note: The other options were not mentioned in the statements and therefore are not the best match.

Question 9

Matching
Match each correct item with the statement below.
-An untagged VLAN on a switch that will automaticallyreceive all untagged frames.Options for nativeVLANs vary according to the switch manufacturer andmodel.

Accepted Answer

The statement describes the concept of a native VLAN, which is a VLAN configured on a trunk port to carry untagged traffic.

Answer: G
 The statement refers to a trunk port, which is used to carry traffic for multiple VLANs using tagging.

Answer: I
 The statement refers to a security attack known as VLAN hopping, which takes advantage of vulnerabilities in the way VLANs are configured on a switch network.

Note: The other options are not directly related to the statements given.
