How does the AOS-CX architecture facilitate this high level of availability?

A.By running a backup copy of the operating system in a virtual machine.
B.All software processes are stateless and read their configuration from the startup-config on every action.
C.Each software module is a self-contained process that interacts with a centralized state database, allowing for independent restarts.

A Network Operator is reviewing the routing table of a switch and sees multiple entries for different types of routes.
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 10.100.1.1
O > 192.168.50.0/24 [110/10] via 10.1.1.2
C > 10.1.1.0/24 is directly connected, vlan1
If the switch receives a packet destined for 192.168.50.75, what is the significance of the value `[110/10]` in the OSPF route entry?

A.The administrative distance is 10, and the OSPF metric is 110.
B.The administrative distance is 110, and the OSPF metric (cost) is 10.
C.The route has been active for 110 minutes and has a cost of 10.
D.The next hop is 110 hops away, and the metric is 10.

Question No : 6

A Network Operator is validating the final configuration of a VSF stack of two CX 6300 switches before putting it into production. The operator needs a single command that provides a comprehensive overview of the VSF stack's health, including the roles of each member and the overall status.
The operator needs to quickly verify:
* The VSF Domain ID.
* The overall status of the stack (e.g., Active).
* Which member is the Commander and which is the Standby.
* The model and MAC address of each member.
Which of the following validation commands provides all this critical information in one consolidated output?

A.`show interface brief`
B.`show lldp neighbor-info`
C.`show vsf`
D.`show vsf link`

Question No : 7

A Network Administrator is troubleshooting an intermittent connectivity issue between two subnets, VLAN 20 and VLAN 30. They suspect a routing loop or a duplicate IP address might be the cause. The administrator wants to trace the Layer 3 path from the default gateway of VLAN 20 (SW-1) to a host in VLAN 30.
Which troubleshooting steps are most effective for diagnosing this issue? (Choose 2.)

A.Use `traceroute <vlan30_host_ip>` on SW-1 to identify the routing path and any potential loops.
B.Use `show mac-address-table` on SW-1 to find the IP address of the host.
C.Use `show arp | include <vlan30_host_ip>` on SW-1 to check for a valid ARP entry.
D.Use `show spanning-tree` on SW-1 to check the Layer 3 routing topology.
E.Use `ping <vlan30_host_ip> repeat 100` on SW-1 to confirm the intermittent nature of the problem.

Question No : 8

A network is being designed to support voice, video, and data. A Solutions Architect needs to explain to the customer why simply having a high-bandwidth network (e.g., 10 Gbps links) is not enough to guarantee high-quality voice and video calls.
Which statements accurately describe the significance of QoS in this high-bandwidth converged network? (Select all that apply.)

A.QoS is not needed because the high bandwidth prevents all forms of congestion.
B.Even on high-bandwidth links, microbursts of traffic can cause momentary congestion, leading to jitter and packet loss for real-time applications.
C.QoS ensures that even if the link is not fully saturated, delay-sensitive packets (like VoIP) are always processed and forwarded first by the switch.
D.QoS is primarily for low-bandwidth networks (less than 1 Gbps).
E.QoS allows the network to provide predictable and reliable service for critical applications, regardless of the other traffic on the network.

Question No : 11

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.Configure OSPF, as static routes do not support failover.
C.The switch will automatically prefer the 1Gbps link based on its interface speed.
D.Change the second route to `ip route 0.0.0.0/0 10.200.1.1 secondary`.

A Junior Network Engineer is tasked with increasing the uplink bandwidth and providing redundancy between a new access layer switch (ALS) and a core switch. The engineer decides to configure a Link Aggregation Group (LAG) using two 10Gbps ports (1/1/47 and 1/1/48) on the ALS. The LAG should be configured to use LACP for dynamic negotiation.
Initial State:
* Ports 1/1/47 and 1/1/48 are physically connected to the core switch.
* The core switch is already configured to use LACP on its corresponding ports.
* The required VLANs are already created on the switch.
Required Configuration:
* Create a Link Aggregation Group numbered 2.
* Configure the LAG to operate in active LACP mode.
* Add physical interfaces 1/1/47 and 1/1/48 as members of LAG 2.
* Enable the LAG interface.
Which of the following configuration sets correctly implements the specified LACP LAG?

A.interface 1/1/47-1/1/48 lacp group 2 mode active interface lag 2 no shutdown
B.interface lag 2 no shutdown lacp mode active ports 1/1/47, 1/1/48
C.interface lag 2 no shutdown lacp mode active interface 1/1/47 lag 2 interface 1/1/48 lag 2
