A customer is having a performance issue on the network and has received complaints about users experiencing intermittent connectivity. After performing a packet capture, it is determined that there is unwanted UDP port 68 traffic being broadcast.
To mitigate this issue, which ArubaOS-CX 6300M switch feature would be best to implement?
To address unwanted UDP port 68 traffic being broadcast, the best feature to implement on an ArubaOS-CX 6300M switch would be DHCPv4-snooping. This feature helps mitigate issues related to DHCP traffic, specifically UDP port 68, by allowing the switch to monitor DHCP messages exchanged between clients and servers. This monitoring helps in preventing malicious or accidental DHCP server replies from misconfigured or rogue devices, thereby improving network performance and reducing unwanted broadcast traffic.
Which MAC address is valid for use as a VSX system-MAC address?
A valid VSX system-MAC address must be a unicast MAC address. Unicast MAC addresses have the least significant bit of the first octet set to 0, indicating that the address is not a multicast address. Additionally, a MAC address should not have all bits set to 1, as this signifies a broadcast address. Option B, AB:00:04:00:FF:00, fits these criteria, making it a valid MAC address for use as a VSX system-MAC address.
A customer would like to utilize some ArubaOS-CX 8325 switches to discard unwanted traffic to the IP address 10.20.30.40.
You enter the following command on the switch:
ip route 10.20.30.40/32 blackhole
What will be the result?
The 'blackhole' option in the 'ip route' command specifies that packets matching the destination route are silently discarded without sending an ICMP error notification to the sender. This means the switch will discard packets to the destined host without any additional notification.
Refer to the exhibit:
Which statement is true?
The configuration in the exhibit defines a Quality of Service (QoS) queue profile (Q1) and a schedule profile (S1). However, for these profiles to take effect and influence traffic handling, they need to be explicitly applied to specific interfaces. This is a common requirement in network devices, where the configuration profiles must be linked to interfaces to become operational.
A customer would like to utilize some ArubaOS-CX 6300M switches to perform OSPF routing.
All ports are routed, and ECMP is enabled, with other default parameters for OSPF. What will be the result of traffic sent from CLIENT-A to CLIENT-B?
In an ECMP (Equal-Cost Multi-Path) scenario with default OSPF parameters, the traffic from CLIENT-A to CLIENT-B will take the path with the highest bandwidth and lowest cost metric. Since SW3 -> SW-1 -> SW-2 and SW3 -> SW-4 -> SW-2 both have sufficient bandwidth, for simplicity and given equal costs, the simplest high-bandwidth path is SW3 -> SW-1 -> SW-2.
