True
- B
False

What term names the approved reference state for a device or service, including relevant settings, software versions, and security controls?
An organization is planning separate subnets for staff and voice devices. Which approach best supports reliable addressing as the organization grows?

- B
Choose nonoverlapping subnets sized for each group's purpose and expected growth
- C
Choose subnet ranges without documenting their purpose or gateway
- D
Use only static addresses and leave the allocation method undocumented
A network team wants monitoring that helps it detect and investigate operational problems. Select all practices supported by effective monitoring.
- A
Set thresholds that reflect service requirements
- B
Treat each alert as an isolated incident and avoid reviewing trends
- C
Route alerts to accountable responders
- D
Review trends rather than treating every alert as an isolated incident
- E
Use centralized, time-synchronized logs to help correlate events
What DHCP scope setting documents addresses that should be withheld from dynamic assignment to help prevent conflicts?
Centralized, logs help administrators correlate events across network devices.
The Syslog specification describes support for TLS-based transport.
- A
True
- B
False
Users can reach a website by its IP address but cannot reach it by its name. What should an administrator test first to investigate the likely cause?
- A
Change the site's routing configuration immediately
- B
Replace the firewall rules before testing anything
- C
Test DNS name resolution
- D
Assume the entire network is unavailable
An organization is preparing a plan to restore critical network services after a disruption. Select all elements the plan should specify.

- C
Responsible personnel

After resolving a network incident, what information should an administrator include in the operational record so another administrator can continue the work and the incident can be reviewed later?
A team is planning maintenance on a branch router and needs to identify which systems may be affected. Which inventory information is most useful for determining that impact?
- A
The router's serial number and date of purchase
- B
The services and systems that depend on the router
- C
The list of all users who connect through the router
- D
The router's physical dimensions and rack position
An office uses separate staff and voice subnets, and some devices have static addresses while others use DHCP. Which addressing-plan practice best helps prevent address conflicts?
- A
Use one DHCP scope for both subnets and leave its settings undocumented
- B
Allow overlapping address ranges so devices can use either subnet
- C
Document separate DHCP scopes and their allocation details, including exclusions and reservations
- D
Assign every device a static address and omit gateway information from the plan
An administrator needs to determine the sequence of events across several network devices. Which logging practice best supports that investigation?
- A
Centralize logs and synchronize device clocks
- B
Keep separate logs on each device and compare their file sizes
- C
Store logs only on the device where each event occurred
- D
Disable timestamps so device clock differences do not affect the records
Users can reach a website by its IP address but not by its name. Which service should an administrator test first? Enter the service name.

- B
Update the inventory only if the change causes an outage
- C
Record the change but do not review it after implementation
- D
Document the change and review it afterward, even if the process was accelerated

- B
Apply one relevant change at a time under change procedures and preserve evidence
- C
Replace the affected equipment before checking logs or monitoring data
- D
Change routing and firewall rules together, then wait to see whether the symptom stops
