Question 70
A portable medical device changes physical switch ports but retains a clinical-network role. Which approach reduces per-port policy edits?
- Static VLAN zoning
- Routed Layer 3 separation
- 802.1X network authentication
- Dynamic Segmentation and roles
Explanation
Correct Answer
D:Role-driven segmentation can decouple policy from attachment point. Identity-driven role assignment can attach network permissions to users and devices instead of fixed physical ports alone.
Incorrect Answers
A:VLANs provide Layer 2 broadcast separation but do not alone prove user identity. But this does not address the case requirement to apply the same authorized role as devices relocate.
B:Routing boundaries connect subnets while restricting broadcast propagation. But this does not address the case requirement to apply the same authorized role as devices relocate.
C:802.1X controls initial port access via supplicant, authenticator and authentication service. But this does not address the case requirement to apply the same authorized role as devices relocate.
Question 71
A campus design shows a RADIUS-backed exchange between a wired client and access port. Which edge process is occurring?
- ACL policy enforcement
- Static VLAN zoning
- Routed Layer 3 separation
- 802.1X network authentication
Explanation
Correct Answer
D:802.1X authenticates the supplicant through an authenticator and backend. 802.1X controls initial port access via supplicant, authenticator and authentication service.
Incorrect Answers
A:ACLs permit or deny matching traffic according to configured direction and precedence. But this does not address the case requirement to validate endpoint identity at admission.
B:VLANs provide Layer 2 broadcast separation but do not alone prove user identity. But this does not address the case requirement to validate endpoint identity at admission.
C:Routing boundaries connect subnets while restricting broadcast propagation. But this does not address the case requirement to validate endpoint identity at admission.
Question 72
Routing works from a guest VLAN into finance, but business rules require denial. What device policy should be evaluated?
- Routed Layer 3 separation
- Static VLAN zoning
- ACL policy enforcement
- MAC authentication fallback
Explanation
Correct Answer
C:Traffic filtering provides enforcement after routing has chosen a path. ACLs permit or deny matching traffic according to configured direction and precedence.
Incorrect Answers
A:Routing boundaries connect subnets while restricting broadcast propagation. But this does not address the case requirement to prevent an unauthorized routed flow.
B:VLANs provide Layer 2 broadcast separation but do not alone prove user identity. But this does not address the case requirement to prevent an unauthorized routed flow.
D:MAC-based methods support some devices lacking 802.1X but require careful weaker-identity controls. But this does not address the case requirement to prevent an unauthorized routed flow.
Question 73
A voice rollout mentions jitter problems but has no traffic map. Which discovery work should precede configuration?
- Port and PoE capacity inventory
- Operational ownership and change windows
- Acceptance and validation criteria
- Traffic and application inventory
Explanation
Correct Answer
D:Application flows and service levels determine bandwidth and QoS needs. Inventorying traffic flows and applications reveals bandwidth, latency, segmentation and critical dependencies.
Incorrect Answers
A:Counting endpoints and power demands identifies the physical switch resources required. But this does not address the case requirement to identify actual application forwarding needs.
B:Roles, maintenance windows and escalation routes reduce rollout risk. But this does not address the case requirement to identify actual application forwarding needs.
C:Objective pass/fail tests define how to confirm the installed network meets requirements. But this does not address the case requirement to identify actual application forwarding needs.
Question 74
An engineer orders switches before measuring endpoint counts and AP power needs. Which pre-work is missing?
- Acceptance and validation criteria
- Security and regulatory requirements
- Operational ownership and change windows
- Port and PoE capacity inventory
Explanation
Correct Answer
D:Port demand and PoE totals must be captured first. Counting endpoints and power demands identifies the physical switch resources required.
Incorrect Answers
A:Objective pass/fail tests define how to confirm the installed network meets requirements. But this does not address the case requirement to size physical ports and powered-device capacity.
B:Identity, encryption, segmentation and audit obligations must shape the wired design. But this does not address the case requirement to size physical ports and powered-device capacity.
C:Roles, maintenance windows and escalation routes reduce rollout risk. But this does not address the case requirement to size physical ports and powered-device capacity.
Question 75
A campus design says highly available without naming which failures may be tolerated. What planning activity is absent?
- Operational ownership and change windows
- Acceptance and validation criteria
- Failure-domain analysis
- Traffic and application inventory
Explanation
Correct Answer
C:Failure-domain analysis converts vague availability into concrete redundant paths. Documenting single points of failure and required recovery behavior guides redundancy choices.
Incorrect Answers
A:Roles, maintenance windows and escalation routes reduce rollout risk. But this does not address the case requirement to identify which single failures the network must survive.
B:Objective pass/fail tests define how to confirm the installed network meets requirements. But this does not address the case requirement to identify which single failures the network must survive.
D:Inventorying traffic flows and applications reveals bandwidth, latency, segmentation and critical dependencies. But this does not address the case requirement to identify which single failures the network must survive.
Question 76
A hospital wants badge readers isolated but the network plan includes only bandwidth figures. What must be added?
- Acceptance and validation criteria
- Traffic and application inventory
- Operational ownership and change windows
- Security and regulatory requirements
Explanation
Correct Answer
D:Compliance and access policies are architectural requirements. Identity, encryption, segmentation and audit obligations must shape the wired design.
Incorrect Answers
A:Objective pass/fail tests define how to confirm the installed network meets requirements. But this does not address the case requirement to capture endpoint authorization and regulatory constraints.
B:Inventorying traffic flows and applications reveals bandwidth, latency, segmentation and critical dependencies. But this does not address the case requirement to capture endpoint authorization and regulatory constraints.
C:Roles, maintenance windows and escalation routes reduce rollout risk. But this does not address the case requirement to capture endpoint authorization and regulatory constraints.
Question 77
A change request says the new building should work but names no measurable result. What document should be improved?
- Acceptance and validation criteria
- Operational ownership and change windows
- Failure-domain analysis
- Security and regulatory requirements
Explanation
Correct Answer
A:Testable acceptance criteria enable unambiguous handover. Objective pass/fail tests define how to confirm the installed network meets requirements.
Incorrect Answers
B:Roles, maintenance windows and escalation routes reduce rollout risk. But this does not address the case requirement to prove that the implementation satisfies approved outcomes.
C:Documenting single points of failure and required recovery behavior guides redundancy choices. But this does not address the case requirement to prove that the implementation satisfies approved outcomes.
D:Identity, encryption, segmentation and audit obligations must shape the wired design. But this does not address the case requirement to prove that the implementation satisfies approved outcomes.
Question 78
An upgrade is scheduled during peak trading with nobody accountable for rollback. Which planning issue needs resolution?
- Operational ownership and change windows
- Security and regulatory requirements
- Port and PoE capacity inventory
- Traffic and application inventory
Explanation
Correct Answer
A:Ownership and maintenance scheduling form part of safe execution. Roles, maintenance windows and escalation routes reduce rollout risk.
Incorrect Answers
B:Identity, encryption, segmentation and audit obligations must shape the wired design. But this does not address the case requirement to assign approvers and an approved maintenance window.
C:Counting endpoints and power demands identifies the physical switch resources required. But this does not address the case requirement to assign approvers and an approved maintenance window.
D:Inventorying traffic flows and applications reveals bandwidth, latency, segmentation and critical dependencies. But this does not address the case requirement to assign approvers and an approved maintenance window.
Question 79
Two power feeds exist but the proposed aggregation pair shares a lone uplink. Which analysis reveals the unresolved risk?
- Acceptance and validation criteria
- Port and PoE capacity inventory
- Operational ownership and change windows
- Failure-domain analysis
Explanation
Correct Answer
D:A redundancy analysis should include all network path dependencies. Documenting single points of failure and required recovery behavior guides redundancy choices.
Incorrect Answers
A:Objective pass/fail tests define how to confirm the installed network meets requirements. But this does not address the case requirement to verify protection against a single uplink failure.
B:Counting endpoints and power demands identifies the physical switch resources required. But this does not address the case requirement to verify protection against a single uplink failure.
C:Roles, maintenance windows and escalation routes reduce rollout risk. But this does not address the case requirement to verify protection against a single uplink failure.
Question 80
After a cutover, stakeholders disagree about what counts as a passing latency test. What should have been defined?
- Acceptance and validation criteria
