Network Operations

Match each network logging and auditing protocol or concept on the left with its corresponding primary characteristic or function on the right.

A network administrator needs to apply a firmware update to several enterprise network switches following standard operational procedures. In which sequential order should the administrator perform the steps of the patch management lifecycle?

A network technician needs to upgrade the firmware on a campus access switch following standard IT service management practices. In what chronological order should the technician execute the steps of the change management lifecycle from first to last?

A network administrator is preparing to perform a routine firmware update on enterprise network switches during a scheduled maintenance window. Which TWO of the following tasks should be completed prior to deploying the patch to the production environment? (Select TWO.)

During a scheduled maintenance window, a network engineer deploys a critical configuration update to an edge router to enable new BGP routing policies. Immediately following the change, internal monitoring alerts show severe packet loss across multiple subnets, and remote sites lose connectivity to the primary datacenter. The engineer suspects a misconfigured route map but realizes that testing during the window ran out of time. According to standard change management procedures, which of the following is the MOST appropriate immediate action for the engineer to take?

A network administrator is upgrading device monitoring and logging protocols across the enterprise network to enforce strict encryption and data integrity standards during auditing. Which of the following configuration options fulfill these secure logging requirements? (Select TWO.)

A network administrator deploys two Layer 3 switches (Switch-Alpha and Switch-Beta) using Hot Standby Router Protocol (HSRP) to provide default gateway redundancy for a server subnet ($10.50.10.0/24$). Switch-Alpha is designated as the primary gateway with an HSRP priority of 120, while Switch-Beta is configured with the default priority of 100. Interface tracking is enabled on Switch-Alpha to decrement its priority by 30 if its uplink interface fails. During a simulated link failure on Switch-Alpha's uplink, its priority drops to 90, allowing Switch-Beta (priority 100) to assume the active gateway role. However, after the uplink link on Switch-Alpha is fully restored and its priority returns to 120, Switch-Beta remains the active gateway while Switch-Alpha stays in standby mode. Which of the following root causes best explains why Switch-Alpha failed to reclaim the active gateway role upon uplink restoration?

Match each remote access or out-of-band management technology on the left with the enterprise scenario on the right for which it is the most appropriate management solution.

A network technician is setting up SNMPv3 on a managed switch to send performance monitoring data securely to a network management server using the authPriv security level. Which TWO of the following algorithms or features must be enabled to satisfy the requirements of this specific security level? (Select TWO.)

A network administrator needs to establish a remote management connection to a core router located at an unstaffed branch office. The solution must grant low-level command-line interface (CLI) access for emergency troubleshooting even if the router's primary operating system network interfaces or main WAN links experience a complete failure. Which of the following solutions best satisfies these requirements?

A network administrator receives a critical security update for an enterprise core router's operating system. Which of the following actions should the administrator take first to ensure network stability before deploying the patch to production?

A network security auditor is reviewing an enterprise organization's network logging and monitoring infrastructure to meet stringent compliance regulations. The audit reveals two major vulnerabilities: (1) SNMP management traffic captures reveal cleartext interface statistics and OID payloads despite network administrators requiring password access to the monitoring console, and (2) during periodic core switch link saturation, critical Syslog alerts from edge devices are consistently dropped before reaching the centralized SIEM. Which combination of configuration updates will resolve both compliance findings by ensuring cryptographic privacy of network management payloads and reliable, tamper-resistant log delivery?

Match each network documentation type to its primary operational purpose.

A network technician is documenting a newly commissioned telecommunications room to assist on-site staff with pinouts, cable runs, wall outlet terminations, and patch panel port locations. The documentation must detail exact physical conductor connections and jack numbers without detailing IP addressing schemes or device rack unit placements. Which document type should the technician prepare?

A principal network architect is designing a high-availability out-of-band (OOB) management framework for a remote enterprise data center. The solution must guarantee secure administrative access to core network appliances and power controls even during a complete collapse of the primary WAN infrastructure and internal LAN control planes. Which TWO of the following deployment strategies directly satisfy these out-of-band access and security requirements? (Select TWO.)

During a physical fiber cut, an enterprise branch site experiences complete loss of its primary and secondary WAN transport links. Network engineers must urgently perform low-level command-line reconfiguration on the core switches and execute a hard power cycle on an unresponsive edge router at the location. Which of the following infrastructure deployment models provides secure emergency administrative access to these hardware assets without depending on the production transport network?

A network administrator configures an active/passive firewall cluster to ensure high availability for an enterprise network. During a failover test, the passive firewall successfully assumes the active role, and newly initiated web traffic flows normally. However, all established, long-lived TCP sessions (such as SSH connections and database transactions) are immediately dropped, forcing users to reconnect. Which of the following is the most likely cause of this issue?

A network administrator needs to monitor performance metrics on core switches while ensuring that all polling traffic is authenticated and payload data is encrypted across the network. Which of the following SNMP configurations should the administrator deploy?

Match each remote management protocol or access method on the left to its correct primary characteristic on the right.

A network operations team is updating telemetry rules and syslog configurations for enterprise core routers and firewalls. Match each network logging mechanism or Syslog severity level on the left with its corresponding operational description on the right.
