NEW QUESTION # 26
A Network Operator is investigating a report of intermittent connectivity between a user in the Sales VLAN (VLAN 10, subnet 192.168.10.0/24) and a server in the Finance VLAN (VLAN 20, subnet 192.168.20.0/24). The operator suspects a routing issue on the core switch that handles inter-VLAN routing.
The operator logs into the core switch and runs `show ip route`.
show ip route
Codes: C - Connected, S - Static, R - RIP, O - OSPF, B - BGP > - Selected route, * - FIB route S > 0.0.0.0/0 [1/0] via 172.16.1.1, vlan1 C > 172.16.1.0/30 is directly connected, vlan1 C > 192.168.10.0/24 is directly connected, vlan10 C > 192.168.20.0/24 is directly connected, vlan20 O > 192.168.30.0/24 [110/2] via 172.16.1.1, vlan1 The routing table appears correct. To investigate the *intermittent* nature of the problem, the operator needs to see the real-time, hop-by-hop path the traffic is taking between the user and the server. Which command should the operator use from the core switch's CLI to trace this path?
- A. `traceroute 192.168.20.5 source 192.168.10.1`
- B. `ping 192.168.20.5`
- C. `show arp | include 192.168.20.5`
- D. `debug ip routing`
Answer: A
NEW QUESTION # 27
How many collision domains are shown in the diagram below?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
Each switch port represents a separate collision domain. The diagram shows six individual Ethernet links (four host-to-access-switch links plus two access-switch-to-SVI device links), so there are six collision domains.
NEW QUESTION # 28
How do you configure an IP address for the management interface on a CX 6300?
- A. vrf mgmt
!
interface mgmt
no shutdown
ip static 10.250.136.52/29
default-gateway 10.250.136.49
vrf attach mgmt - B. interface mgmt
no shutdown
ip address 10.250.136.52/29
default-gateway 10.250.136.49
vrf attach mgmt - C. interface mgmt
no shutdown
ip address 10.250.136.52/29
default-gateway 10.250.136.49 - D. interface mgmt
no shutdown
ip static 10.250.136.52/29
default-gateway 10.250.136.49
Answer: A
Explanation:
On a CX 6300, the management interface operates in the dedicated mgmt VRF. The correct configuration uses a static IP address on the mgmt interface and explicitly attaches that interface to the mgmt VRF, ensuring management traffic is properly separated from the data plane.
NEW QUESTION # 29

- A. Broadcast domains are mainly a problem when you use a hub device.
- B. Collisions are quite common in modern network switches.
- C. A switch port defines the edge of a collision domain.
- D. A routing device defines the edge of a broadcast domain.
- E. Collision domains relate to Layer 2 processes, while broadcast domains are a Layer 3 concept.
Answer: B,D

- A. ZTP
- B. Single-mode fiber
- C. Multi-mode fiber
- D. UTP
Answer: B
Explanation:
A 40 Gbps link over a distance of 35 km requires single-mode fiber, which is designed to support high-speed optical transmission over long distances without significant signal loss.
NEW QUESTION # 31
Drag and Drop Question
Match each example to the corresponding security concept.
Answer:
Explanation:
Explanation:
Alice has entered the correct password: Authentication
An auditor is granted read-only access to create a compliance report: Authorization Bob is permitted to run the CLI command "show running-config" only: Role-based Access Control Trudy modified the switch config via CLI on Tuesday the 2nd of July 2024: Accounting Authentication verifies a user's identity by validating credentials. Authorization defines what level of access a verified user is granted. Role-based access control enforces permissions based on assigned roles and allowed commands. Accounting records and tracks user actions for auditing and accountability purposes.
NEW QUESTION # 32
Refer to the diagram below. After a recent network change, the helpdesk reports that some users could not connect to the print server. Server-1, which is in VLAN 20. After further investigation, you find that only devices directly connected to Access-2 are affected. Which part of the network should you investigate?
- A. The configured VLAN on Access-2 port 1/1/4.
- B. The link status of Access-2 port 1/1/28.
- C. Subnet mask on clients connected to Access-2.
- D. Allowed VLANs between access switches.
Answer: D
Explanation:
Only clients connected to Access-2 are affected, while the server is also on Access-2 in VLAN 20.
This points to VLAN 20 not being consistently carried across the inter-switch trunk after the change, so traffic from some Access-2 user ports mapped to VLAN 20 would fail to reach Server-
1. Checking the trunk's allowed VLAN list between the access switches verifies whether VLAN 20 is permitted end-to-end.
NEW QUESTION # 33
A network administrator is designing a network with a redundant path between two distribution switches. To prevent Layer 2 loops while allowing for fast failover, the administrator has enabled Rapid Spanning Tree Protocol (RSTP).
What is the primary advantage of using RSTP (802.1w) over the original Spanning Tree Protocol (STP, 802.1D)?
- A. RSTP supports more VLANs than STP.
- B. RSTP significantly reduces the convergence time after a link failure.
- C. RSTP uses a more secure method for electing the root bridge.
- D. RSTP allows all ports to forward traffic simultaneously by load balancing.
Answer: B

NEW QUESTION # 37
Why would a device perform an ARP request?
- A. To find the source IP address for a specific MAC address.
- B. To find the destination MAC address for a specific IP address.
- C. To find the IP address for a specific MAC address.
- D. To find the source MAC address for a specific IP address.
Answer: B
Explanation:
A device uses ARP to resolve an IP address to its corresponding MAC address so it can correctly deliver Ethernet frames on the local network.
