Question #21
Which two statements are true about IDS Signatures? (Choose two.)
- A . Users can upload their own IDS signature definitions.
- B . An IDS signature contains data used to identify known exploits and vulnerabilities.
- C . An IDS signature contains data used to identify the creator of known exploits and vulnerabilities.
- D . IDS signatures can be High Risk, Suspicious, Low Risk and Trustworthy.
- E . An IDS signature contains a set of instructions that determine which traffic is analyzed.
Correct Answer: BE
BE
Explanation:
According to the Network Bachelor article1, an IDS signature contains data used to identify an attacker’s attempt to exploit a known vulnerability in both the operating system and applications. This implies that statement B is true. According to the VMware NSX Documentation2, IDS/IPS Profiles are used to group signatures, which can then be applied to select applications and traffic. This implies that statement E is true. Statement A is false because users cannot upload their own IDS signature definitions, they have to use the ones provided by VMware or Trustwave3. Statement C is false because an IDS signature does not contain data used to identify the creator of known exploits and vulnerabilities, only the exploits and vulnerabilities themselves. Statement D is false because IDS signatures are classified into one of the following severity categories: Critical, High, Medium, Low, or Informational1.

Question #24
What can the administrator use to identify overlay segments in an NSX environment if troubleshooting is required?
- A . VNI ID
- B . Segment ID
- C . Geneve ID
- D . VIAN ID
Correct Answer: A
A
Explanation:
According to the VMware NSX Documentation1, a segment is mapped to a unique Geneve segment that is distributed across the ESXi hosts in a transport zone. The Geneve segment uses a virtual network identifier (VNI) as an overlay network identifier. The VNI ID can be used to identify overlay segments in an NSX environment if troubleshooting is required.

Question #25
What are two valid BGP Attributes that can be used to influence the route path traffic will take? (Choose two.)
- A . AS-Path Prepend
- B . BFD
- C . Cost
- D . MED
Correct Answer: AD
AD
Explanation:
AS-Path Prepend: This attribute allows you to prepend one or more AS numbers to the AS path of a route, making it appear longer and less preferable to other BGP routers. You can use this attribute to manipulate the inbound traffic from your BGP peers by advertising a longer AS path for some routes and a shorter AS path for others.
MED: This attribute stands for Multi-Exit Discriminator and allows you to specify a preference value for a route among multiple exit points from an AS. You can use this attribute to manipulate the outbound traffic to your BGP peers by advertising a lower MED value for some routes and a higher MED value for others .

Question #26
Which command is used to display the network configuration of the Tunnel Endpoint (TEP) IP on a bare metal transport node?
- A . tepconfig
- B . ifconfig
- C . tcpdump
- D . debug
Correct Answer: B
B
Explanation:
The command ifconfig is used to display the network configuration of the Tunnel Endpoint (TEP) IP on a bare metal transport node2. The TEP IP is assigned to a network interface on the bare metal server that is used for overlay traffic. The ifconfig command can show the IP address, netmask, broadcast address, and other information of the network interface. For example, the following command shows the network configuration of the TEP IP on a bare metal transport node with interface name ens192:
ifconfig ens192
The output of the command would look something like this:
ens192: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.10.10.10 netmask

Question #29
What needs to be configured on a Tler-0 Gateway lo make NSX Edge Services available to a VM on a VLAN-backed logical switch?
- A . Downlink Interface
- B . VLAN Uplink
- C . Loopback Router Port
- D . Service Interface
Correct Answer: D
D
Explanation:
The service interface is a special-purpose port to enable services for mainly VLAN-based networks. North-south service insertion is another use case that requires a service interface to connect a partner appliance and redirect north-south traffic for partner services. Service interfaces are supported on both active-standby Tier-0 logical routers and Tier-1 routers. Firewall, NAT, and VPNs are supported on this interface. The service interface is also a downlink

Question #30
A company Is deploying NSX micro-segmentation in their vSphere environment to secure a simple application composed of web. app, and database tiers.
The naming convention will be:
• WKS-WEB-SRV-XXX
• WKY-APP-SRR-XXX
• WKI-DB-SRR-XXX
What is the optimal way to group them to enforce security policies from NSX?
- A . Use Edge as a firewall between tiers.
- B . Do a service insertion to accomplish the task.
- C . Group all by means of tags membership.
- D . Create an Ethernet based security policy.
Correct Answer: C
C
Explanation:
The answer is C. Group all by means of tags membership.
Tags are metadata that can be applied to physical servers, virtual machines, logical ports, and logical segments in NSX. Tags can be used for dynamic security group membership, which allows for granular and flexible enforcement of security policies based on various criteria1
In the scenario, the company is deploying NSX micro-segmentation to secure a simple application composed of web, app, and database tiers.
The naming convention will be:
– WKS-WEB-SRV-XXX
– WKY-APP-SRR-XXX
– WKI-DB-SRR-XXX
The optimal way to group them to enforce security policies from NSX is to use tags membership. For
example, the company can create three tags: Web, App, and DB, and assign them to the corresponding VMs based on their names. Then, the company can create three security groups: Web-SG, App-SG, and DB-SG, and use the tags as the membership criteria. Finally, the company can create and apply security policies to the security groups based on the desired rules and actions2
Using tags membership has several advantages over the other options:
– It is more scalable and dynamic than using Edge as a firewall between tiers. Edge firewall is a centralized solution that can create bottlenecks and performance issues when handling large amounts of traffic3
– It is more simple and efficient than doing a service insertion to accomplish the task. Service insertion is a feature that allows for integrating third-party services with NSX, such as antivirus or intrusion prevention systems. Service insertion is not necessary for basic micro-segmentation and can introduce additional complexity and overhead.
– It is more flexible and granular than creating an Ethernet based security policy. Ethernet based security policy is a type of policy that uses MAC addresses as the source or destination criteria. Ethernet based security policy is limited by the scope of layer 2 domains and does not support logical constructs such as segments or groups.
