Which technology prevents client devices from arbitrarily connecting to the network without state remediation?
The correct answer is B. Option B: 802.1x
Which protocol does an access point use to draw power from a connected switch?
The correct answer is B. Option B: Cisco Discovery Protocol
An administrator must secure the WLC from receiving spoofed association requests. Which steps must be taken to configure the WLC to restrict the requests and force the user to wait 10 ms to retry an association request?
The correct answer is D. Option D: Enable the Protected Management Frame service and set the Comeback timer to 10. This option keeps traffic private / properly secured as required.
Refer to the exhibit. Only four switches are participating in the VLAN spanning-tree process. Branch-1: priority 614440 - Branch-2: priority 39391170 - Branch-3: priority 0 - Branch-4: root primary - Which switch becomes the permanent root bridge for VLAN 5?
The correct answer is C. Option C: Branch-3
An engineer must configure traffic for a VLAN that is untagged by the switch as it crosses a trunk link. Which command should be used?
The correct answer is D. Option D: switchport trunk native vlan 10
Explanation
A trunk carries traffic for multiple VLANs between network devices. Frames in the native VLAN are untagged by default on an 802.1Q trunk. A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure.
What are two benefits of using the PortFast feature? (Choose two.)
The correct answer is C, D. Option C: Enabled interfaces never generate topology change notifications. Option D: Enabled interfaces come up and move to the forwarding state immediately.
What is the benefit of configuring PortFast on an interface?
The correct answer is B. Option B: After the cable is connected, the interface is available faster to send and receive user data.
Why does a switch flood a frame to all ports?
The correct answer is B. Option B: The destination MAC address of the frame is unknown.
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. NAT translates addresses between network domains, commonly conserving public IPv4 addresses.
An engineer configures interface Gi1/0 on the company PE router to connect to an ISP. Neighbor discovery is disabled. Which action is necessary to complete the configuration if the ISP uses third-party network devices?
The correct answer is B. Option B: Enable LLDP globally.
Explanation
LLDP is the vendor-neutral IEEE neighbor discovery protocol.
Which access point mode relies on a centralized controller for management, roaming, and SSID configuration?
The correct answer is A. Option A: lightweight mode
Refer to the exhibit. A network engineer must configure communication between PC A and the File Server. To prevent interruption for any other communications, which command must be configured?
The correct answer is C. Option C: switchport truck allowed vlan add 13
Explanation
A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure.
Refer to the exhibit. What is the result if Gig1/11 receives an STP BPDU?
The correct answer is C. Option C: The port goes into error-disable state.
Which access layer threat-mitigation technique provides security based on identity?
The correct answer is C. Option C: 802.1x This option keeps traffic private / properly secured as required.
Refer to the exhibit. Which action do the switches take on the trunk link?
The correct answer is B. Option B: The trunk forms, but the mismatched native VLANs are merged into a single broadcast domain.
Explanation
A trunk carries traffic for multiple VLANs between network devices. Frames in the native VLAN are untagged by default on an 802.1Q trunk. A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure.
A network engineer must configure two new subnets using the address block 10.70.128.0/19 to meet these requirements: • The first subnet must support 24 hosts. • The second subnet must support 472 hosts. • Both subnets must use the longest subnet mask possible from the address block. Which two configurations must be used to configure the new subnets and meet a requirement to use the first available address in each subnet for the router interfaces? (Choose two.)
The correct answer is A, E. Option A: interface vlan 1148 ip address 10.70.148.1 255.255.254.0 Option E: interface vlan 155 ip address 10.70.155.65 255.255.255.224
Explanation
A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure. OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
Refer to the exhibit. An administrator must configure interfaces Gi1/1 and Gi1/3 on switch SW11. PC-1 and PC-2 must be placed in the Data VLAN, and Phone-1 must be placed in the Voice VLAN. Which configuration meets these requirements?
The correct answer is A. Option A: interface gigabitethernet1/1 switchport mode access switchport access vlan 8 ! interface gigabitethernet1/3 switchport mode access switchport access vlan 8 switchport voice vlan 9
Explanation
A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure.
Refer to the exhibit. Users need to connect to the wireless network with IEEE 802.11r-compatible devices. The connection must be maintained as users travel between floors or to other areas in the building. What must be the configuration of the connection?
The correct answer is C. Option C: Enable Fast Transition and select the FT PSK option.
Refer to the exhibit. An engineer is asked to insert the new VLAN into the existing trunk without modifying anything previously configured. Which command accomplishes this task?
The correct answer is D. Option D: switchport trunk allowed vlan add 104
Explanation
A trunk carries traffic for multiple VLANs between network devices. A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure.
Aside from discarding, which two states does the switch port transition through while using RSTP (802.1w)? (Choose two.)
The correct answer is D, E. Option D: learning Option E: forwarding
Which interface mode must be configured to connect the lightweight APs in a centralized architecture?
The correct answer is C. Option C: access
