Remote users are granted access to the network through the core.
Routing should be configured without traffic filtering, address translation, or other packet manipulation at the core
The core, which acts as the front door to a network, is designed to prevent unauthorized users from gaining entry.
The core provides an optimized and reliable transport structure by using a combination of route summaries, distribution lists, and route maps

Interfaces Fa0/1 through Fa0/6 are trunk ports.
Switch DLS1 is not the root bridge for VLAN 1.
The Cost column in the lower part of the exhibit is not the cumulative root path cost.
The default spanning-tree timers have been adjusted.
That Fa0/12 is displaying the alternate port role indicates that PVRST+ is enabled.
The QoS requirements should accommodate the best effort delivery for voice traffic
The QoS requirements should accommodate the bursty nature of voice traffic.
The QoS requirements should accommodate the intensive demand on bandwidth for voice traffic
The QoS requirements should accommodate the smooth demand on bandwidth, low latency, and delay for voice traffic.
Use HSRP instead of GLBP
Adjust the GLBP timers.
Configure spanning tree so that the spanning-tree topology adjusts with the GLBP active virtual forwarder (AVF).
Disable GLBP preemption on all route processors.
UDLD stops trying to establish a connection with the neighbor.
UDLD changes the port state to err-disable.
UDLD changes the port to loop-inconsistent blocking state.
UDLD sends hello messages to its neighbor at a rate of one per second to attempt to recover the connection.
As a trunk port
As a routed port
As an access port
As a switched virtual interface
Keep voice and data traffic in the same VLAN and mark the traffic for high priority treatment.
Create voice VLANs to keep voice traffic separate from other data to ensure special handling of the traffic.
Configure traffic shaping QoS policy to guarantee minimum delay for the voice traffic.
Configure QoS policy to classify the voice traffic in the priority queue to guarantee reserved bandwidth allocation for the traffic.
Configure the Weighted Random Early Detection (WRED) congestion avoidance mechanism to guarantee that the voice traffic will be placed in the priority queue.
Wrong IP address or subnet mask
Ports in the wrong VLAN
Mismatch between SVI and VLAN numbering
Disabled VTP pruning
ACL on wrong interface
Weighted round robin (WRR) queuing
Native VLAN mismatch
Switchport mode mismatch
Local username and password
RADIUS server and, if that fails, local username and password
TACACS+ server and, if that fails, local username and password
RADIUS server and, if that fails, TACACS+ server
Root guard should be implemented on the Layer 2 ports between the distribution switches.
PortFast should be implemented on the uplink ports from the access switches to the distribution switches.
Loop guard should be implemented on the Layer 2 ports between DSW1 and DSW2 and on the uplink ports from the access switches to the distribution switches.
BPDU guard should be implemented on the Layer 2 ports between DSW1 and DSW2 and on the uplink ports from the access switches to the distribution switches.
Replying to ARP requests that are intended for other recipients
Sending malicious dynamic trunking protocol (DTP) frames
Replying to DHCP requests that are intended for a DHCP server
Sending a unicast flood of Ethernet frames with distinct source MAC addresses
Sending frames with two 802.1Q headers
All interfaces on links 5 and 6
All interfaces on links 1, 2, 3, and 4
All interfaces on links 1, 2, 3, 4, 5, and 6
All interfaces between the distribution and the access switches
BPDU guard is enabled
Cisco Discovery Protocol (CDP) is disabled.
VLAN trunking protocol (VTP) is disabled.
PortFast is enabled.
Trunking is disabled.
Channel group is disabled.
A routed port behaves like a regular router interface and supports VLAN subinterfaces.
A routed port is a physical switch port with Layer 2 capability.
A routed port is not associated with a particular VLAN.
To create a routed port requires removal of Layer 2 port functionality with the no switchport interface configuration command.
The interface vlan global configuration command is used to create a routed port.
Spanning-tree load balancing is in effect.
All VLANs are mapped to MST instance 2.
PVRST+ is still operating on switch DLS1.
PVST+ is still operating on switch DLS1.
MST will require fewer resources than PVST+ or PVRST+.
Applying the standby 32 timers 10 30 command on the Gi0/2 interfaces of each switch would decrease the failover time
If the DSw1 and DSw2 switches have been configured to preempt, then DSw2 will be the active router.
If the DSw1 switch is configured with the standby preempt command and DSw2 is not, then DSw1 will be the active router.
The HSRP group number in this HSRP configuration is HSRP group number 50.
The standby track command is useful for tracking interfaces that are not configured for HSRP.
When host A sends an ARP request for 10.10.10.1, Virtual Router replies with the MAC address of the active router.
