Which QoS feature drops traffic that exceeds the committed access rate?
The correct answer is A. Option A: policing
What does traffic shaping do?
The correct answer is A. Option A: It queues excess traffic
Refer to the exhibit. A Cisco engineer is asked to update the configuration on switch 1 so that the EtherChannel stays up when one of the links fails. Which configuration meets this requirement?
The correct answer is B. Option B: Switch1(config) # interface port-channel 1Switch1(config-if) # port-channel min-links 1
Which two protocols are supported on service-port interfaces? (Choose two.)
The correct answer is A, D. Option A: Telnet Option D: SSH
Explanation
SSH provides encrypted remote CLI administration and should replace insecure Telnet.
What is the benefit of using private IPv4 addressing?
The correct answer is B. Option B: to shield internal network devices from external access This option keeps traffic private / properly secured as required.
Two switches have been implemented and all interfaces are at the default configuration level. A trunk link must be implemented between two switches with these requirements: • using an industry-standard trunking protocol • permitting VLANs 1-10 and denying other VLANs How must the interconnecting ports be configured?
The correct answer is C. Option C: switchport mode trunkswitchport trunk encapsulation dot1qswitchport trunk allowed vlans 1-10
Explanation
A trunk carries traffic for multiple VLANs between network devices. A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure.
Refer to the exhibit. Traffic that is flowing over interface TenGigabitEthemet0/0/0 experiences slow transfer speeds. What is the cause of this issue?
The correct answer is C. Option C: duplex incompatibility
Explanation
PAT distinguishes many inside sessions on one public address by translating transport-layer ports.
Which two host addresses are reserved for private use within an enterprise network? (Choose two.)
The correct answer is A, D. Option A: 10.172.76.200 Option D: 172.31.255.100 This option keeps traffic private / properly secured as required.
Refer to the exhibit. The iPv6 address for the LAN segment on router R2 must be configured using the EUI-64 format. Which address must be used?
The correct answer is A. Option A: ipv6 address 2001:DB8:D8D2:1009:10A0:ABFF:FECC:1 eui-64
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. IPv6 uses 128-bit addresses and relies on Neighbor Discovery rather than ARP.
What are two reasons to configure PortFast on a switch port attached to an end host? (Choose two.)
The correct answer is B, D. Option B: to enable the port to enter the forwarding state immediately when the host boots up Option D: to protect the operation of the port from topology change processes
A network administrator wants the syslog server to filter incoming messages into different files based on their importance. Which filtering criteria must be used?
The correct answer is B. Option B: level
Which interface or port on the WLC is the default for in-band device administration and communications between the controller and access points?
The correct answer is B. Option B: management interface
Refer to the exhibit. A network administrator configures the CPE to provide internet access to the company headquarters. Traffic must be load-balanced via ISP1 and ISP2 to ensure redundancy. Which two command sets must be configured on the CPE router? (Choose two.)
The correct answer is C. Option C: ip route 0.0.0.0 0.0.0.0 198.51.100.1ip route 0.0.0.0 0.0.0.0 203.0.113.1
Refer to the exhibit. A network engineer updates the existing configuration on interface fastethernet1/1 switch SW1. It must establish an EtherChannel by using the same group designation with another vendor switch. Which configuration must be performed to complete the process?
The correct answer is C. Option C: interface fastethernet 1/1channel-group 2 mode active
Which two characteristics are representative of virtual machines (VMs)? (Choose two.)
The correct answer is A, E. Option A: multiple VMs operate on the same underlying hardware Option E: Each VM runs independently of any other VM in the same hypervisor
What is the recommended switch load-balancing mode for Cisco WLCs?
The correct answer is D. Option D: source-destination MAC address
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.
What must be considered when using 802.11a?
The correct answer is D. Option D: It is used in place of 802.11b/g when many nonoverlapping channels are required
Refer to the exhibit. An engineer configures interface fa0/1 on SW1 and SW2 to pass traffic from two different VLANs. For security reasons, company policy requires the native VLAN to be set to a nondefault value. Which configuration meets this requirement?
The correct answer is A. Option A: Switch(config-if)#switchport mode trunkSwitch(config-if)#switchport trunk encapsulation dot1qSwitch(config-if)#switchport trunk allowed vlan 100,105Switch(config-if)#switchport trunk native vlan 3
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. This option keeps traffic private / properly secured as required.
Refer to the exhibit A new VLAN and switch are added to the network. A remote engineer configures OldSwitch and must ensure that the configuration meets these requirements: • accommodates current configured VLANs • expands the range to include VLAN 20 • allows for IEEE standard support for virtual LANs Which configuration on the NewSwitch side of the link meets these requirements?
The correct answer is D. Option D: no switchport trunk encapsulation islswitchport trunk encapsulation dot1qswitchport trunk allowed vlan add 20
Explanation
A trunk carries traffic for multiple VLANs between network devices. A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure.
Refer to the exhibit. A network engineer is adding another physical interface as a new member to the existing Port-Channel1 bundle. Which command set must be configured on the new interface to complete the process?
The correct answer is A. Option A: no switchportchannel group 1 mode active
