CCA-AppDS-Gateway sample questions

Question 1

An infrastructure architect is designing a new NetScaler 14.x deployment. The requirement is that the NetScaler must reside on a single subnet, and all traffic from the clients to the backend servers must route through the NetScaler interface, but the backend servers reside on a different subnet entirely. The NetScaler must perform source IP translation to ensure return traffic flows back through it.

Which deployment mode is the architect implementing?

Accepted Answer

One-Arm Mode

Answer

Direct Server Return (DSR) Mode

Answer

Inline Mode

Answer

Two-Arm Mode

Question 2

True or False: When a content switching virtual server is configured with both a backup virtual server and a redirect URL, the redirect URL takes precedence, so clients are redirected as soon as the primary content switching virtual server goes DOWN, even if the backup virtual server is UP.

Accepted Answer

False

Answer

True

Question 3

A systems engineer is configuring a NetScaler 14.x appliance to load balance traffic for a group of internal application servers. The NetScaler needs to communicate with these backend servers over a specific VLAN. Which NetScaler IP address type is specifically designed and required to originate traffic from the NetScaler to the backend servers?

Accepted Answer

SNIP (Subnet IP)

Answer

MIP (Mapped IP)

Answer

NSIP (NetScaler IP)

Answer

VIP (Virtual IP)

Question 4

A financial enterprise is deploying a NetScaler 14.x appliance in a highly segregated network environment. The network security team has mandated the following constraints:

1. The NetScaler management interface (NSIP) must reside on VLAN 10.
2. Client traffic will enter via the DMZ on VLAN 20.
3. Backend database servers reside on a secure internal segment on VLAN 30.
4. The NetScaler must not use regular IP routing lookups to determine the return path for client traffic on VLAN 20, as there are multiple asymmetric routing paths possible in the DMZ. It must return the packet to the exact MAC address of the router that sent it.

Which feature must the network administrator enable globally on the NetScaler to satisfy constraint #4?

Accepted Answer

MAC Based Forwarding (MBF)

Answer

Use Source IP (USIP) mode

Answer

Policy-Based Routing (PBR)

Answer

Layer 2 Mode (L2 Mode)

Question 5

A network administrator is reviewing the Access Control List (ACL) configuration on a NetScaler 14.x appliance. There are multiple ACLs configured with different priorities. The administrator notices that traffic intended to be blocked by 'ACL_Block_Malicious' is still being permitted.

Assuming the ACLs are applied correctly, what is the most likely reason for this behavior?

Accepted Answer

The 'ACL_Block_Malicious' rule has a higher priority number than a conflicting ALLOW rule.

Answer

Extended ACLs always take precedence over Simple ACLs regardless of priority numbering.

Answer

The administrator forgot to reboot the NetScaler after applying the ACL.

Answer

The 'ACL_Block_Malicious' rule has a lower priority number than a conflicting ALLOW rule.

Question 6

When configuring Link Aggregation on a NetScaler 14.x appliance to increase bandwidth and provide redundancy to the core switch, which protocol is recommended to dynamically negotiate the bundled links?

Accepted Answer

LACP (Link Aggregation Control Protocol)

Answer

GARP (Gratuitous Address Resolution Protocol)

Answer

OSPF (Open Shortest Path First)

Answer

VRRP (Virtual Router Redundancy Protocol)
