HPE7-A01 Practice Test

Explanation:

An inbound ACL is applied to traffic entering a port or VLAN. An outbound ACL is applied to traffic leaving a port or VLAN4. To deny ping sourcing from the user VLAN to the IT management VLAN, an inbound ACL on the user VLAN should be used to filter icmp echo traffic toward the IT management VLAN. Icmp echo-reply traffic is not needed to be allowed because it is already permitted by default5.

Explanation:

Encryption is a feature supported by SNMPv3 that provides an advantage over SNMPv2c. Encryption protects the confidentiality and integrity of SNMP messages by encrypting them with a secret key. SNMPv2c does not support encryption and relies on community strings for authentication and authorization, which are transmitted in clear text and can be easily intercepted or spoofed. Transport mapping, community strings, and GetBulk are features that are common to both SNMPv2c and SNMPv3.

Explanation:

To configure an IP address for an interface in default state for interface 1/1/1 on Aruba CX 6300 switch, you need to disable switching on the interface first with the command no switching. Then you can assign an IP address with the command ip address. The other options are incorrect because they either do not disable switching or use invalid keywords such as switching or routing.

Explanation:

The correct answer is A. SNMPv3.

SNMPv3 is a protocol that is used to retrieve data stored in a Management Information Base (MIB), which is a database of managed objects in a network. SNMPv3 provides security and access control features that are not available in earlier versions of SNMP. SNMPv3 can also use encryption to protect the data from unauthorized access or modification.

According to the Aruba Certified Professional – Campus Access document1, one of the skills that this certification validates is:

• Implement and Analyze the output from common network monitoring tools The document also mentions that the candidate should have a distinguished understanding of different protocols across vendors, which implies that they should be familiar with SNMPv3 and how it can be used to access MIB data.

Explanation:

The active gateway feature is used to provide active-active layer 3 default gateway for hosts on the same subnet. It allows the switch to convert multicast streams into unicast streams over the wireless link, which improves the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. The active gateway feature is unique to VSX configuration because it eliminates the need for VRRP and avoids traffic being pushed over the ISL link, which can cause latency in the network12.

The correct answer to the question is C. Sixteen different VMACs are supported for each IPv4 and IPv6 stack simultaneously. This means that you can have a maximum of eight VMACs for IPv4, and a maximum of eight VMACs for IPv6, on a VSX pair. Only 15 VMACs are supported on 6400 switch series2.

The other options are incorrect because:

• A. Sixteen different VMACs are not supported total as shared. They are supported for each IPv4 and IPv6 stack separately.

• B. Active gateway can be used without MSTP instances. MSTP is a protocol that allows multiple spanning tree instances to coexist on the same switch, but it does not affect how active gateway works.

• D. Active gateway does not copy traffic over the ISL link for an optimized path. It avoids using the ISL link for routed traffic and uses the local switch interface MAC instead of the virtual MAC address (VMAC) for source address1.
