A network administrator is transitioning a company's internal services to an IPv6 infrastructure and verifying host configuration parameters and DNS record deployments. Which of the following statements regarding IPv6 addressing syntax rules and deployment mechanisms are correct? (Select TWO.)

An enterprise network administrator notices that wireless clients in a branch office are repeatedly disconnected from the secure corporate Wi-Fi network. Subsequent packet analysis reveals a stream of spoofed 802.11 management frames instructing host devices to sever their existing wireless associations, followed immediately by hosts connecting to an unauthorized access point operating on a higher-power channel while broadcasting the identical corporate Service Set Identifier (SSID). Which network attack vector is being executed?

A network administrator is deploying a $2.4\text{ GHz}$ wireless network across three adjacent zones in an office building. To achieve higher throughput, the administrator originally configured all three access points to use $40\text{ MHz}$ channel bonding. However, client devices in the overlap areas experience frequent packet loss and degraded performance due to adjacent-channel interference. Which configuration change should the administrator implement to resolve the interference while preserving continuous wireless coverage?

A network technician is troubleshooting a complete link failure across a 500-meter single-mode fiber-optic run that connects two building distribution switches through an underground conduit. The technician needs to determine whether the fiber core has suffered a physical break and measure the exact distance to the fault location from the patch panel. Which diagnostic tool should the technician use?

An enterprise network operations center manages a critical financial application server. The server's disaster recovery policy dictates a full system image backup every Sunday at 01:00 AM, along with cumulative differential backups executed each night from Monday through Saturday at 11:00 PM. On Friday at 10:00 AM, a storage controller failure permanently corrupts the primary volume. What is the minimum and correct sequence of backup restoration operations required to bring the system back to its most recent consistent operational state?

A network administrator is investigating two distinct issues following an office expansion: several new workstation copper cabling drops are experiencing intermittent physical link loss, while other hosts on the subnet are intermittently failing to obtain valid IP configuration settings due to suspected rogue server activity on the local VLAN. Which of the following tools and diagnostic approaches should the technician utilize to isolate these issues? (Select TWO)

A network administrator is investigating connectivity and performance problems on an 802.1Q trunk link connecting a distribution switch to a newly provisioned access switch. Syslog entries on the distribution switch repeatedly record %CDP-4-NATIVE_VLAN_MISMATCH alerts. Furthermore, interface status reports on the trunk link display a high count of late collisions and frame check sequence (FCS) errors on one side, alongside significant packet drops. Which TWO of the following root causes are responsible for these symptoms? (Select TWO.)

A network technician is troubleshooting an issue where a dual-stack client workstation fails to connect to an internal host named `app-server.corp.local` over IPv6. The technician runs `nslookup -type=AAAA app-server.corp.local` and receives a response stating that the domain name does not exist. However, executing `nslookup app-server.corp.local` successfully returns the IPv4 address $10.1.10.45$. Which of the following is the most likely cause of this issue?

Following an office wall installation project, a workstation loses network access. A network technician suspects that a 120-meter Category 6 unshielded twisted-pair (UTP) cable running through the wall cavity has been physically severed by a drywall fastener. Which diagnostic tool should the technician use to determine the exact distance along the cable run to the location of the break?

A desktop technician is systematically troubleshooting a workstation on a newly configured subnet ($10.80.12.0/24$) that cannot access network resources. The workstation failed to acquire a lease from the enterprise DHCP server located on a separate server subnet ($10.10.2.0/24$). Following standard troubleshooting methodology from the local client to the centralized infrastructure, in what order should the technician perform these diagnostic and verification steps?

A network administrator receives alerts that newly deployed IP security cameras in a logistics facility are unable to communicate with the central surveillance management server. Examination of a affected camera's network configuration reveals an IP address of $192.168.1.105$ with a default gateway of $192.168.1.1$. However, the camera VLAN is defined as $10.120.45.0/24$ with leases managed by a central enterprise DHCP server at $10.100.10.50$. Which of the following is the most likely cause of this issue?

A network engineer is deploying wireless access points equipped with directional patch antennas along high-ceiling inventory aisles in a logistics warehouse. The objective is to provide clear coverage along narrow aisle corridors while minimizing co-channel interference and signal leakage into adjacent parallel aisles. Which of the following deployment parameters and configuration settings should the engineer implement? (Select TWO.)

An organization is updating its disaster recovery plan for a mission-critical e-commerce application. The business continuity policy mandates a Recovery Time Objective (RTO) of less than 15 minutes and a Recovery Point Objective (RPO) of near zero (under 1 minute). Which TWO of the following deployment and recovery strategies will meet both requirements?

A network engineer is deploying new point-of-sale (POS) terminals on VLAN 105 ($192.168.105.0/24$). The enterprise central DHCP server resides on VLAN 10 ($10.10.10.2$). During initial testing, the POS terminals fail to obtain leased IP addresses and continuously self-assign IP addresses in the range of $169.254.1.1$ through $169.254.254.254$. Which of the following potential root causes or diagnostic actions should the engineer investigate to resolve this connectivity issue? (Select TWO.)

A system administrator is restoring an enterprise Network Management System (NMS) server after a storage volume corruption on Friday at 09:00. The established backup strategy executes a full backup every Sunday at 00:00 and differential backups every evening at 23:00 from Monday through Thursday. To achieve complete recovery to the latest available state with minimal restoration steps, which backup restoration sequence must be executed?

Match each physical layer cabling fault or task scenario with the diagnostic tool or equipment best suited to identify or resolve it.

A network engineer is configuring a newly installed multi-floor wireless deployment for a medical clinic. The deployment must support high-density client access on both the $2.4\text{ GHz}$ and $5\text{ GHz}$ bands while minimizing co-channel and adjacent-channel interference between adjacent access points (APs). Which of the following design and configuration strategies should the engineer implement to fulfill these requirements? (Select TWO.)
