A network engineer is configuring a backup floating IPv6 static route on router R1 toward destination prefix $2001:\text{db8}:7410:\text{a1}::/64$. The next-hop router is identified by its link-local address $\text{fe80}::\text{cafe}:1$ over local interface $\text{GigabitEthernet0/0/0}$. The route must be configured with an administrative distance of $140$. Fill in the missing parameters in the command snippet below.

An enterprise router has populated its IPv4 routing table with the following entries:

text
D 10.50.0.0/16 [90/2560512] via 10.1.1.1, 01:12:40, GigabitEthernet0/0
O 10.50.12.0/24 [110/20] via 10.1.1.2, 00:45:12, GigabitEthernet0/1
S 10.50.12.80/28 [1/0] via 10.1.1.3
S 10.50.12.80/29 [250/0] via 10.1.1.4

The router receives a packet with a destination IP address of $10.50.12.85$. Which next-hop IP address will the router select to forward this packet?

A network technician is adding a secondary path on Router-HQ to reach the internal subnet $172.16.40.0/24$. The primary link currently learns this destination via EIGRP with an administrative distance of 90. To ensure the secondary static path through next-hop IP $10.1.1.2$ serves strictly as a backup when the primary link is down, which Cisco IOS command must be configured?

A network administrator is evaluating transport layer requirements for a real-time voice conferencing application and a critical database replication service. Which two operational characteristics accurately describe User Datagram Protocol (UDP) when compared to Transmission Control Protocol (TCP)? (Select two.)

A network administrator needs to establish out-of-band administrative access to a Cisco Wireless LAN Controller (WLC) for system maintenance. The out-of-band management network uses subnet $192.168.100.0/24$, which is completely isolated from production wireless client traffic and general infrastructure VLANs. Which physical interface and configuration method on the WLC should the administrator use to achieve this isolated management connection?

A network administrator is evaluating campus design options for a multi-floor office building with modest bandwidth requirements. The team decides to implement a 2-Tier Collapsed Core topology instead of a traditional 3-Tier Cisco Campus architecture. Which of the following statements accurately describe the structural and operational traits of this Collapsed Core design? (Select two.)

Match each Cisco Lightweight Access Point (AP) operational mode on the left with its corresponding functional behavior and traffic forwarding characteristics on the right.

A network administrator is allocated the IPv6 prefix block $2001:\text{db8}:\text{acad}:4000::/52$ for a corporate branch network. The administrator needs to divide this block into standard $/64$ subnets for local LAN segments. How many $/64$ subnets can be created from this $/52$ prefix block?

An administrator needs to create a new WPA2-Personal WLAN using the Cisco Wireless LAN Controller (WLC) GUI. Place the steps in the correct chronological order to complete this configuration.

A Cisco router receives an IP packet and initiates a route lookup process to select the optimal path. Arrange the router forwarding decision logic steps in the correct sequential order from first to last.

An engineer is attempting to deploy a routed Layer 3 EtherChannel between two distribution switches. The logical interface `Port-channel 1` has been configured with `no switchport` and assigned an IPv4 address. However, executing `show etherchannel summary` reveals the following output:

text
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator

Group Port-channel Protocol Ports
------+-------------+----------+-----------------------------------------------
1 Po1(SD) LACP Gi0/1(I) Gi0/2(I)

Which configuration step is required on the local switch to resolve this issue and bring the EtherChannel to an operational `SU` state?

In a Cisco centralized wireless network deployment, how does a Lightweight Access Point (LAP) operating in default Local mode handle wireless client data traffic?

An administrator is configuring client connectivity for a new wireless network using the Cisco Wireless LAN Controller (WLC) web interface. The WLAN must use WPA2-Personal (PSK) authentication and be mapped to a dedicated dynamic interface. Arrange the GUI configuration steps in the correct sequential order from first to last.

A network engineer is configuring IP address assignments for client workstations within a corporate VLAN allocated the $10.150.32.0/21$ IPv4 block. Which two IP addresses are valid host addresses that can be assigned to devices on this subnet?

An infrastructure analyst is performing a security review of an enterprise management network. The organization requires per-command authorization for administrative CLI access on routers and switches, along with full packet payload encryption between network devices and the central AAA server. Which security protocol satisfies these requirements?

Match each VPN framework element on the left with its primary functional purpose on the right.

During a physical security compliance evaluation of a remote edge facility, an auditor notes three vulnerability findings: unauthorized personnel entering the main telecommunications enclosure by following authorized employees (tailgating), unmonitored physical patch panel connections in public hallways, and employee badges left unattended at desktop terminals. To address these vulnerabilities, the security team must implement controls classified specifically under physical access control mechanisms and administrative security program elements. Which combination of measures correctly pairs a physical access control with an administrative security program element to directly address these findings?

A network administrator is configuring Quality of Service (QoS) classification using Differentiated Services (DiffServ) on an enterprise router. How many bits are allocated to the Differentiated Services Code Point (DSCP) field within the IPv4 Type of Service (ToS) byte?

A network administrator is using Software Image Management (SWIM) within Cisco DNA Center to upgrade a Catalyst switch. Place the steps of the standard SWIM deployment workflow in the correct operational sequence from first to last.

A network administrator is onboarding a brand-new Cisco Catalyst switch into an enterprise network using Cisco Catalyst Center (formerly Cisco DNA Center) Network Plug and Play (PnP). Place the steps of the Day-0 PnP device discovery and provisioning process into the correct operational sequence from first to last.
