A network administrator needs to convert two physical switch interfaces (GigabitEthernet0/1 and GigabitEthernet0/2) on a Cisco Catalyst switch into a routed (Layer 3) EtherChannel bundle using dynamic LACP active mode. In what sequential order should the Cisco IOS configuration commands be executed to successfully establish the routed port-channel interface and configure its IP addressing?

Match each fully expanded IPv6 address on the left with its standard canonical compressed representation on the right according to RFC 5952 rules.

A network administrator needs to explicitly configure switch interface GigabitEthernet0/3 as a static access port belonging to VLAN 30. Which set of commands must be executed in interface configuration mode to achieve this configuration?

Place the following Cisco IOS configuration commands in the correct order to create VLAN 30, assign it the name 'ENGINEERING', and configure interface GigabitEthernet1/0/15 as a static access port in VLAN 30, starting from privileged EXEC mode (`Switch#`).

A network engineer deploys a Layer 2 switch to connect 24 host workstations within a single IP subnet. The switch connects upstream directly to a single Ethernet interface on a enterprise router. Assuming standard full-duplex switch port configurations and no VLAN segmentation, how do the Layer 2 switch and the router function regarding collision domains and broadcast domains for this segment?

Match each transport layer characteristic or mechanism on the left to its corresponding protocol behavior on the right.

An enterprise network architect is designing a Variable Length Subnet Mask (VLSM) address allocation plan starting at the base private IPv4 block $10.200.16.0/20$. Three internal subnets must be allocated sequentially in contiguous order from the lowest available boundary:

- Subnet A (WLAN Clients): Requires at least $1,000$ usable host IP addresses
- Subnet B (VoIP Phones): Requires at least $450$ usable host IP addresses
- Subnet C (Management): Requires at least $60$ usable host IP addresses

If Subnet A is allocated first, followed immediately by Subnet B, and then Subnet C, what is the valid usable host IPv4 address range for Subnet C?

A network engineer is configuring a point-to-point connection and internal VLANs within an enterprise infrastructure. An interface is assigned the IPv4 address $10.144.67.100/21$. What is the decimal value of the third octet of the broadcast address for the subnet to which this host belongs?

An edge switch port connected directly to an end-host is configured with Cisco STP PortFast. Which operational benefit does PortFast provide when this link transitions to an up state?

An enterprise security audit reveals two critical vulnerabilities in a campus network infrastructure: administrative command entries sent to network switches during remote management sessions are logged in cleartext without granular per-command authorization, and unauthorized rogue devices plugged into active wall jacks in common areas gain immediate access to internal network segments. Which two security mitigations directly resolve these specific vulnerabilities? (Select two.)

A network engineer is analyzing packet captures from a site-to-site IPsec VPN tunnel operating between two enterprise edge routers across an intermediate Internet Service Provider network with Port Address Translation (PAT). The captured traffic shows that Encapsulating Security Payload (ESP) is encapsulated inside UDP port 4500 packets rather than transmitted directly over IP protocol 50. Which statement correctly explains why UDP encapsulation was dynamically negotiated for this IPsec tunnel?

A Cisco router receives an IPv4 packet destined for $10.25.8.12$. The router inspects its routing table and finds the following matching route entries:

text
S 10.25.0.0/16 [1/0] via 172.16.1.1
O 10.25.8.0/23 [110/30] via 172.16.2.1
D 10.25.8.0/27 [90/2170112] via 172.16.3.1
S* 0.0.0.0/0 [1/0] via 172.16.0.1

Which next-hop IP address will the router choose to forward this packet?

A network administrator executes the `show cdp neighbors` command on a Cisco Catalyst switch to inspect connected devices and receives the following output:

Device ID Local Intrfce Holdtme Capability Platform Port ID
SW-ACCESS-02 Gig 0/1 162 R S I WS-C3560 Gig 0/24

Based on this command output, which interface on the local switch directly connects to neighboring switch SW-ACCESS-02?

A network administrator needs to configure an IPv6 static route on a Cisco IOS router to reach the destination prefix $2001:\text{db8}:1:10::/64$. Which of the following commands represent valid IPv6 static route configurations? (Select TWO.)

A network administrator is configuring a Cisco Catalyst switch running Rapid PVST+ to serve as a secondary root bridge for VLAN 20. The administrator intends to set a custom bridge priority using the command `spanning-tree vlan 20 priority <value>`. Which value will Cisco IOS accept for this command?

An administrator examines an IPv4 routing table entry on a Cisco router:

`D 192.168.50.0/24 [90/2170112] via 10.1.1.2, 00:04:12, GigabitEthernet0/1`

Which two statements correctly describe the components of this routing entry? (Select TWO.)

A network administrator needs to configure a static route on a Cisco router to reach destination network $2001:\text{DB8}:\text{ABCD}:10::/64$. The adjacent router's link-local address is $\text{FE80}::2:1$ and the local outbound interface is GigabitEthernet0/0. Which Cisco IOS command correctly configures this IPv6 static route?

A network engineer transitions several Cisco Lightweight Access Points (LAPs) deployed at a branch office from default Local mode to FlexConnect mode with local switching enabled for the corporate employee wireless network. The switch ports connected to these APs are currently configured as Layer 2 access ports assigned to VLAN 10 (Management). Following the transition, AP-to-WLC CAPWAP control connectivity remains healthy, but wireless clients connecting to the employee SSID (mapped to VLAN 20) fail to obtain IP addresses or communicate with local resources. Which configuration change must be applied to the access switch ports to restore client connectivity on the employee WLAN?

A network engineer is interconnecting two legacy network switches via their FastEthernet interfaces. Neither switch interface supports IEEE 802.3ab Auto-MDIX. Which physical cable type and pin mapping must be used on this link to establish Layer 1 connectivity?

Match each VPN implementation type or protocol combination on the left with its corresponding operational characteristic on the right.
