NEW QUESTION # 22
A solutions architect is designing a resilient routing solution for a campus network. A critical requirement is that if a primary link to the internet fails, traffic must automatically re-route through a secondary link with minimal packet loss. The primary link has a bandwidth of 1Gbps and the secondary link is 100Mbps.
The administrator is considering using static routes.
Review the following proposed configuration on the core switch:
ip route 0.0.0.0/0 10.100.1.1
ip route 0.0.0.0/0 10.200.1.1
How can the administrator ensure the 1Gbps link (via 10.100.1.1) is the primary path and the
100Mbps link (via 10.200.1.1) is only used for failover?
- A. Add the metric `200` to the static route pointing to `10.200.1.1`.
- B. Change the second route to `ip route 0.0.0.0/0 10.200.1.1 secondary`.
- C. The switch will automatically prefer the 1Gbps link based on its interface speed.
- D. Configure OSPF, as static routes do not support failover.
Answer: A
NEW QUESTION # 23
You are trying to configure VSF on a pair of CX 8325 series switches. What would cause the following error?
Switch-1(config)# vsf member 2
Invalid input: vsf
Switch-1(config)#
- A. CX 8325 series switches do not support VSF.
- B. Both of the switches require a firmware update.
- C. VSF must be enabled globally on both switches first.
- D. VSF ports must be physically connected first.
Answer: A
Explanation:
The CX 8325 series does not support Virtual Switching Framework (VSF). VSF is supported on access and aggregation CX platforms such as the CX 6200, 6300, and 6400, but not on data center-focused models like the CX 8325, which instead support technologies such as VSX.

NEW QUESTION # 29
A junior network engineer is studying for a certification and needs to understand how a router makes a forwarding decision when it has multiple routes to the same destination network.
Consider the following entries in a routing table:
S > 0.0.0.0/0 [1/0] via 10.1.1.1
O > 172.16.0.0/16 [110/20] via 10.2.2.2
S > 172.16.10.0/24 [1/0] via 10.3.3.3
If the router receives a packet with a destination IP address of 172.16.10.5, which route will it use?
- A. The OSPF route to 172.16.0.0/16 because OSPF is a dynamic protocol.
- B. The router will load balance the traffic between the OSPF and the static route.
- C. The static route to 172.16.10.0/24 because it is the most specific match.
- D. The default route to 0.0.0.0/0 because it has the lowest administrative distance.
Answer: C

NEW QUESTION # 38
How can an administrator verify that an Aruba switch is forwarding traffic correctly?
- A. show running-config
- B. show interfaces
- C. show ip route
- D. show vlan
Answer: B
Explanation:
The show interfaces command is the most appropriate tool to verify if an Aruba switch is forwarding traffic correctly. It provides detailed statistics about each interface, including:
Interface status (whether the port is up or down)
Traffic statistics (input/output bytes, packets, errors, discards, etc.) Link status (e.g., whether the link is physically operational) Traffic flow (whether data is being transmitted or received on the port) This allows the administrator to check if traffic is being forwarded on the interfaces and identify any issues, such as errors or drops, that might indicate a problem with forwarding traffic.

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.
