Question 1

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.

DNATs provide a many-to-one mapping between IP addresses.

Answer : A, C

Question 2

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 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 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 5

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 6

Generally speaking, should the monitor templates be used as production monitors or should they be customized prior to use.

AMost templates, such as http and tcp, are as effective as customized monitors.

BMonitor template customization is only a matter of preference, not an issue of effectiveness or performance.

CMost templates, such as https, should have the receive rule customized to make the monitor more robust.

DWhile some templates, such as ftp, must be customized, those that can be used without modification are not improved by specific changes.

Answer : C

Question 7

The ICMP monitor has been assigned to all nodes. In addition, all pools have been assigned custom monitors. The pool is marked available. If a pool is marked available (green) which situation is sufficient to cause this?

AAll of the pool member nodes are responding to the ICMP monitor as expected.

BLess than 50% of the pool member nodes responded to the ICMP echo request.

CAll of the members of the pool have had their content updated recently and their responses no longer match the monitor.

DOver 25% of the pool members have had their content updated and it no longer matches the receive rule of the custom monitor. The other respond as expected.

Answer : D
