F5 Networks 201 Exam Practice Test Instant Access

Question 1

Assume a client's traffic is being processed only by a NAT; no SNAT or virtual server processing takes place. Also assume that the NAT definition specifies a NAT address and an origin address while all other settings are left at their defaults. If the origin server were to initiate traffic via the BIG-IP,

What changes, if any, would take place when the BIG-IP processes such packets?

AThe BIG-IP would drop the request since the traffic didn't arrive destined to the NAT address.

BThe source address would not change, but the destination address would be changed to the NAT address.

CThe source address would be changed to the NAT address and destination address would be left unchanged.

DThe source address would not change, but the destination address would be changed to a self-IP of the BIG-IP.

Answer : C

Question 2

Which two statements are true about SNATs? (Choose two.)

ASNATs are enabled on all VLANs, by default.

BSNATs can be configured within a Profile definition.

CSNATs can be configured within a Virtual Server definition.

DSNAT's are enabled only on the VLAN where origin traffic arrives, by default.

Answer : A, C

Question 3

A BIG-IP has two load balancing virtual servers at 150.150.10.10:80 and 150.150.10.10:443. The port 80 virtual server has SNAT automap configured. There is also a SNAT configured at 150.150.10.11 set for a source address range of 200.200.1.0 / 255.255.255.0. All other settings are at their default states. If a client with the IP address 200.200.1.1 sends a request to https://150.150.10.10,

What is the source IP address when the associated packet is sent to the pool member?

A200.200.1.1

B150.150.10.11

CFloating self IP address on VLAN where the packet leaves the system

DFloating self IP address on VLAN where the packet arrives on the system

Answer : B

Question 4

Which statement is true concerning SNATs using automap?

AOnly specified self-IP addresses are used as automap addresses.

BSNATs using automap will translate all client addresses to an automap address.

CA SNAT using automap will preferentially use a floating self-IP over a nonfloating self-IP.

DA SNAT using automap can be used to translate the source address of all outgoing traffic to the same address regardless of which VLAN the traffic is sent through.

Answer : C

Question 5

Which two statements are true about NATs? (Choose two.)

ANATs support UDP, TCP, and ICMP traffic.

BNATs can be configured with mirroring enabled or disabled.

CNATs provide a one-to-one mapping between IP addresses.
