Section 2.2 Demonstrate your acquired knowledge about Configuring Switching Technologies & Features. This will demonstrate your proficiency for section 2.2 of the Network+ 10-009 objectives. 1 / 25 What is typically used to assign a Layer 3 IP address to a VLAN interface? IP helper address Switchport VLAN Switch Virtual Interface (SVI) DHCP relay 2 / 25 Which technology allows for high availability and redundancy on a switch uplink? Port mirroring Spanning Tree Protocol VLAN pruning Static NAT 3 / 25 What is the impact of mismatched native VLANs on trunk ports? Trunk negotiation fails completely VLANs will be encrypted incorrectly Unintended VLAN leaks or security issues can occur STP automatically disables the trunk 4 / 25 Which command enables trunking on a Cisco switch port using 802.1Q? switchport mode access vlan trunk enable switchport mode trunk set trunk encapsulation isl 5 / 25 Which VLAN ID range is reserved and cannot be used for standard VLANs? 1-1001 1002-1005 1006-4094 4095-8192 6 / 25 Which of the following is a requirement for jumbo frames to function properly? STP must be enabled All devices in the path must support the larger MTU VLANs must be tagged with 802.1X Native VLAN must be reconfigured 7 / 25 What is the primary benefit of using jumbo frames? Reduces transmission time by allowing larger payloads per frame Encrypts frames on Layer 2 Increases compatibility with legacy devices Prioritizes traffic automatically 8 / 25 What is the default MTU size on Ethernet frames? 1200 bytes 1500 bytes 9000 bytes 512 bytes 9 / 25 Which STP protocol allows for multiple VLANs to share a single STP instance? PVST+ RSTP MST IEEE 802.1D 10 / 25 Which STP enhancement provides faster convergence by allowing ports to bypass listening and learning states? PortFast LACP BPDU Guard Loopback Detection 11 / 25 Which STP role is assigned to a port that will block traffic to prevent loops? Root Designated Blocking Forwarding 12 / 25 Which port type does STP select to forward traffic toward the root bridge? Root port Alternate port Disabled port Passive port 13 / 25 What is the primary function of Spanning Tree Protocol (STP)? To increase switch port speeds To allow VLANs to communicate without a router To prevent switching loops in a Layer 2 topology To encrypt VLAN traffic on trunk ports 14 / 25 Why is it important to match speed settings on both ends of a switch link? To avoid VLAN trunking issues To prevent link aggregation loops To avoid interface errors and connectivity issues To reduce MAC address table flooding 15 / 25 Which duplex setting allows simultaneous transmission and reception of data? Auto Half duplex Full duplex Simplex 16 / 25 If a port is configured with full duplex but the connected device uses half duplex, what might result? Higher speed Duplex mismatch and collisions Increased VLAN priority Trunk negotiation failure 17 / 25 What protocol is commonly used for dynamic link aggregation? STP 802.1X LACP CDP 18 / 25 What does link aggregation accomplish on a switch? It compresses multiple VLANs into a single stream It allows multiple physical links to function as one logical link It mirrors traffic across ports for monitoring It encrypts traffic between switches 19 / 25 802.1Q tagging is used for what purpose in switching? To tag STP packets for loop detection To assign MAC addresses dynamically To identify VLANs on trunk ports To monitor broadcast traffic 20 / 25 What is the purpose of a voice VLAN? To separate VoIP traffic for QoS and performance optimization To provide encryption for voice communications To prioritize video conferencing traffic To allow voice traffic to bypass firewalls 21 / 25 Which VLAN is used by default for untagged traffic on a trunk port? VLAN 0 VLAN 1002 Native VLAN Management VLAN 22 / 25 What is the function of a Switch Virtual Interface (SVI)? It allows physical switches to forward frames to routers It enables routing between VLANs on a Layer 2 switch It provides a physical interface for VLAN traffic It connects trunk ports together 23 / 25 What is the purpose of the VLAN database on a switch? To store MAC addresses of VLAN members To define and manage VLANs before assigning them to ports To configure port speed and duplex settings To store spanning-tree topology data 24 / 25 Which command type is typically used to assign a port to a VLAN on a managed switch? switchport mode trunk interface vlan switchport access vlan [VLAN-ID] vlan routing enable 25 / 25 What is the primary purpose of a VLAN in a switched network? To increase broadcast domains within a switch To reduce the number of switches required To separate traffic into logically isolated broadcast domains To increase the speed of trunk ports Your score is 0% Restart quiz Return to CompTia N+ 10-009 Objectives
